Readers'

INDUSTRY

NEWS

NOTES

THERE

IS

a good deal of news about companies in

the

computer field,

and

several of our readers have told

us

in vigorous language

that

we

should publish

the

news.

So,

in this issue we publish

the

first instalment

of "Industry News Notes."

As

usual,

we

invite our readers to send

us

information

for publication when it

is

of general interest,

and

to

send

us

corrections, revisions, and additions.

FRONT

COVER:

SPACISTOR

THE

FRONT

COVER

picture

is

a photo of an

assembly of an experimental spa

cis

tor (see

the

story in

this issue) made

at

Raytheon Mfg. Co., photographed

together with an ordinary pin (at

the

left)

to

show the

miniature scale.

The

leads of

the

spacistor are: upper left, injector,

with

point

contact; upper right, modulator, with fused

contact; bottom, collector, a thick broad contact;

slanting crossbar at left, base with fused contact.

The

spacistor in

the

picture

is

attached to a small transistor

mount

shaped something like a boat.

A voltage, applied to

the

injector, causes electrons to

enter

the

region of high electric field (caused by voltage

applied between

the

base and

the

collector in such a

way

as

to produce a high electric field

but

virtually no

current).

The

electrons

flow

extremely rapidly to the

collector contact. This current (flow of electrons)

is

modulated by applying a signal to

the

modulator.

The

modulator draws only a negligible current,

but

causes

the current between

the

injector and collector to vary

greatly. Thus

the

spacistor

is

an amplifier.

SCIENCE

FICTION

ABOUT

COMPUTERS

WE

HAVE

just about decided not to publish any

more science fiction about computers in

the

regular

issues of Computers

and

Automation.

The

reasons are

these. First,

the

readers who do not wish to have science

fiction in

the

magazine apparently outnumber those

who like it. Second, some prospective advertisers or their

agencies appear to feel

that

they do

not

wish their

ad-

vertising to appear in a magazine which publishes

science fiction, no matter how worth while

it

may be.

Finally, and much

the

most important, more and more

nonfiction of undeniable importance to computer

people

is

pressing for publication upon

the

space avail-

able in

the

magazine.

Nevertheless, sound scientific speculation about future

possibilities of computers, expressed in

the

medium of

science fiction,

is

important and useful to many com-

And

we hope

that

we may

be

able to

about computers.

us

what you think.

PREPRINTS

AND

PUBLICATION

I.

From

Eric

A.

Weiss,

Chainnan, Computer Committee, Sun Oil Co.

Philadelphia

3,

Pa.

AS

CHAIRMAN

of

the

Preprints Committee of

the

Thirteenth National Meeting of

the

Association for

Computing 1tIachinery, I have

the

duty of assembling

and distributing preprints of

the

papers

to

be presented

there (Urbana, Ill., June

11-13,

1958).

In

doing this, I

will be asked by some speakers whether or

not

a paper

which appears

as

a preprint will

be

barred on this

account from publication in your journal.

In

order to

clarify

the

matter, I should like to have a brief state-

ment of your policy in this regard.

The

following details concerning

the

preprints may

have some bearing on

the

matter:

The

preprints will not include all papers to be given,

since speakers are under no compulsion to submit their

papers for preprinting.

The

preprints will be distributed to those who

register for

the

meeting, either free or

at

a small fee.

The

preprints will be available for a limited time

after

the

meeting to anyone for a fee.

II:

From

the

Editor

THE

FACT

that

a preprint of a paper has been dis-

tributed

at

a meeting makes no difference whatever to

publication

in

our magazine.

If

the

paper

is

one suit-

able for publication in Computers

and

Automation,

we

shall be glad to consider it for publication, irrespective,

of

the

preprint.

The

existence of preprints, however,

will make it easier for

us

to seek

out

a paper

that

we

would like to publish, provided

the

author does

not

prefer to have

it

published elsewhere.

In

addition,

the

availability of

the

preprints will

be

very helpful to many

people in

the

computer field.

THE SPACISTOR-A

NEW

KIND

OF

SEMICONDUCTOR AMPLIFIER

Neil

D.

M3cdonald

New York, N.

Y.

I.

Computing A

Hundred

Times Faster?

ON July

16

in Boulder, Colorado, Dr. Herman

Statz, Dr. Robert Pucel, and Mr. Conrad Lanza

of Raytheon Manufacturing Co. gave a paper

at

the

session on semiconductors of

the

Institute of Radio

Engineers

and

the

American Institute of Electrical

Engineers.

The

paper announced a device which they

called

the

"spacistor". This name denotes a semicon-

ductor amplifying

and

switching device which makes

good use of a new effect,

the

creation of a high elec-

trical space charge in what

was

previously a transistor.

The

word "spacistor"

is

not a proprietary name

but

a

proposed scientific term.

About eight to ten laboratory models of spacistors

have been constructed,

and

they work; and

the

evidence

is

good

that

spacistors will work in many kinds of new

applications, giving new powers

t~

electronic equipment

including computers.

Although

the

existing models have been tested only

up to about

800

kilocycles, there

is

excellent evidence

that

spacistors will work

at

frequencies up to

100

to

10,000 megacycles.

The

device itself and

the

theory of

the

device together suggest

that

the

speed of pulses in

computers for calculating purposes may

be

raised from

a million pulses per second to

1000

million pulses per

second.

If

even a part of this promise

is

realized,

it

means

that

a dramatic new gain in -speed for computers

is

about to be seized.

The

spacistor

is

almost certainly a step forward in

the

art of amplifying electronic energy. It

is

expected to

combine many of the best features of

the

properties of

the transistor

and

the

vacuum tube.

It

is

as

tiny

as

a

transistor, and operates on

the

same miniature power

requirements, far less than those of vacuum tubes. It

is

predicted

that

the

spacistor will amplify

at

frequencies

up to 10,000 megacycles, considerably higher than will

transistors.

Also, spacistors can be made of materials unsuited for

transistors, and are expected to operate

at

temperatures

as

high

at

500

degrees centigrade, or more than double

the

operating temperatures of today's germanium and

silicon transistors.

The

spacistor

is

the

outcome of two years of intensive

research, and may take three to

five

years more research

and development before

it

is

commercially available.

II.

Comparison

of

the

Vacuum

Tube,

the

Transistor

and

the

Spacistor

In

a vacuum tube (see

the

diagram),

the

cathode

is

heated by a filament heater. A large number of electrons

boil off

the

negative cathode and are attracted to

the

positive plate.

The

small fluctuating signal, to

be

am-

plified,

is

applied

to

the

negative grid

as

shown. This

TUBE

causes

the

negative grid voltage to fluctuate accordingly.

The

more negative

the

grid

the

smaller

the

current

(flow of electrons) between cathode and plate.

The

more positive

the

voltage on

the

grid,

the

larger

the

current between cathode and plate.

Thus

the

grid acts

as

a valve or shutter, a very small

signal controlling a relatively large current.

The

large

output

signal (shown under plate)

is

the

amplified

counterpart of

the

small input signal. In some vacuum

tubes,

the

choice of voltages and other factors may

yield a signal gain of several thousand.

In a typical transistor of

the

type called n-p-n

grounded base (see

the

diagram), a steady negative

TRANSISTOR

voltage

is

applied in a circuit from

the

emitter to

the

base contact, and a greater steady negative voltage

is

applied in a circuit from

the

base contact to

the

col-

lector. This causes significant currents (flows of elec-

trons) from

the

emitter into

the

base region and from

the

base region into

the

collector, because of

spatial proximity of

the

emitter

and

the

collector;

but

the

current from

the

base contact to

the

collector

is

negligible.

A small negative voltage

as

a fluctuating or switching

signal may now be applied in

the

circuit from the

emitter to

the

base contact; this signal produces a

greatly multiplied fluctuating or switching signal from

the

base contact to

the

collector. Because

the

input

current from

the

emitter into

the

base region

is

just

about

the

same

as

the

current from

the

base region into

the

collector, yet

the

resistance from

the

emitter to

the

base region

is

only a fraction of

the

resistance

(say

1/30

to 1/100) of

the

resistance from

the

base region to

the

collector, a power gain of

30

to

100

times results.

In

this

way

the

transistor amplifies.

In

a typical spacist?r (see

the

diagram), a high steady

SPACISTOR

~COLLECTOR

negative voltage

is

applied in a circuit through

the

load

from

the

base to

the

collector, in such a

way

as

to

produce a high electric field

but

almost no current.

Then

a steady negative voltage

is

applied in a circuit

from

the

injector to

the

space-charge region. This causes

electrons to enter

the

region of

the

high electric field,

and flow extremely rapidly to

the

collector. This current

(flow of electrons)

is

modulated by

the

application of a

negative voltage

as

a fluctuating or switching signal in a

circuit from

the

modulator to

the

space-charge region.

The

choice of voltages may make

the

greater current

from

the

in jector to

the

collector

3000

times

the

smaller

current from

the

modulator to

the

collector; and

the

gain factor may rise considerably. In this

way,

a

spacistor amplifies.

III.

Technical Description

The

purpose of

the

design of

the

spacistor

was

to

overcome

the

frequen~y

limitations of

the

transistor by

avoiding

the

slow diffusion of charge carriers (electrons

or "holes") through

the

base region. Carrier motion

accross

the

base region of a transistor

is

slow because

this region

is

essentially free of an electric field.

It

is

true

that

the

base region of a diffused transistor has a

built-in field,

but

its strength

is

severely limited. Very

much higher field strengths, however, are found in space-

charge regions in reverse-biased junctions; in fact,

the

strength of an electric field

is

limited only by

the

break-

down voltage of

the

semiconductor body.

The

spa

cis

tor

8

makes use of these high fields to accelerate

the

charge

carriers

so

that

their transit time

is

greatly shortened.

A typical experimental spacistor

is

shown schematical-

ly

in Fig.

The

p-n junction with a space-charge region sc. Injector I

,2,:),

battery no. one, two, three.

Injector I

is

connected to base B through battery

B~

which biases I negatively with respect to

the

underlying

space-charge region

sc.

(Note

that

the

potential of point

I

is

still positive with respect to

point

B.) Electrons are

emitted from I

int~

sc,

and

the

emission

is

space-

charge-limited.

Modulator M

is

connected to

the

space-charge region

sc

at

a

point

between injector I

and

the

n region of

the

semiconductor body. Since M

is

biased negatively with

respect to

sc

by means of battery

B2,

holes cannot

flow

from

the

p region of

the

semiconductor body

to

sc;

therefore M draws practically

no

current. (Note

that

the

potential

at

M

is

still positive with respect to B

and I.)

Modulator M has two functions. First,

it

varies

the

emission of injector I by superimposing an a.c. voltage

on

the

d.c. bias.

The

field produced by M penetrates

throughout

the

space-charge region to its boundaries.

Second, modulator M makes

the

bias of injector I

practically independent of

the

voltage applied across

the

base B and

the

collector C

so

as

to keep

the

output

impedance desirably high -in excess of

30

megohms,

for an injected current of 0.3 milliamperes.

Transconductance

(gm)

of present experimental

spacistors

is

considerably below

that

of good vacuum

tubes but, with further development,

it

is

expected

that

comparable values will

be

attained.

A low-frequency power gain of 70 db has already been

achieved with experimental spacistors

at

low frequencies.

higher frequencies

as

well.

When

the

present

input

of

30

megohms

is

improved, power gain

is

expected to become

so

great

that

it

will

be

more

appropriate to talk

about

voltage gain,

as

in

the

case of

a vacuum tube. A voltage gain of

3000

has already been

achieved.

Output

capacitance

is

exceedingly small because of

the

wide space-charge region, and values smaller

than

1

micromicrofarad appear entirely feasible. Even with

the

relatively low transconductance values obtained in

present spacistors,

it

is

expected

that

tuned amplifiers

can be built which will operate

at

frequencies corre-

sponding to approximately

the

inverse transit time

through

the

space-charge regions, i.e., frequencies in

excess of

1000

megacycles_

Input

and

output

are decoupled to a high degree

as

in a vacuum

tube

- a useful property in

the

design of

multi-stage circuitry.

Another important advantage of

the

spacistor

is

that

its operation

is

practically independent of the "lifetime"

of

the

charge-carrier.

It

should therefore

be

feasible

to

employ

not

only germanium

and

silicon

but

also other

semiconductor materials whose short "lifetime" makes

them unsuitable for transistors. Silicon carbide and other

materials with large energy gaps are promising possi-

bilities for high-temperature spacistors.

COMPUTER APPLICATIONS

TO

POULTRY

FEED

Wilbur E. Clark

AM

JUST

back from a three-day poultry conference

at

Penn

State University where one day

at

lunch

I

talked with

the

executive secretary

of

a millers and

feed dealers association.

He

told

me

that

at

least two

major feed companies are now using

the

services of

these large computers in this

way:

Each day they telephone to

the

computer service

(which

is

retained on an hourly service basis)

the

closing

prices

at

Chicago on

the

various feed grains

and

ingre-

dients such

as

corn, oats, barley, soybean oil meal, etc.

The

computer has already stored

up

the

various kinds

of ingredients

that

may

be

substituted for each other,

depending on current prices, kind of feed formula being

manufactured, etc. (It's a very involved business, manu-

facturing a certain poultry feed with definite percent-

ages of protein, fat, fiber, ash, vitamins, antibiotics,

and

all

the

other additives

that

make up a modern feed

formula.)

The

data are fed into

the

computer,

and

about

10

minutes later the machine types

out

the

exact infor-

mation telling which ingredients are

the

best buys of

the

day to make a particular formula feed.

This information

was

formerly arrived

at

by a corps

of some

25

skilled office workers

an-d

nutritionists.

As

a

result of

the

change,

one

feed company estimates a

saving of over $100,000 a year and, besides, gets

the

information much faster

so

that

it

can take advantage

of a price situation before

it

changes.

AIRLINE AUTOMATION: A MAJOR STEP

c.

E. Ammann

Director, Advanced Process Research

American Airlines

New York, N.

Y.

T

HE

airlines present an excellent example of a fast

growing industry.

As

is

often

the

case in such

industries, some parts of

the

business took great

strides while others remained practically dormant.

Im~'

provements in aircraft over

the

years reduced

the

flying

time across

the

country from a matter of days to a

matter of hours, yet only

the

simplest of tools were

available to process

the

passenger's reservation.

For example, in

1931

it took three days to

fly

from

New York to Los Angeles in

the

Fokker FlO.

In

1934,

by

a combination of the DC-2 and Curtiss Condor, it

was

possible to make this trip in

21

hours. Today, you

fly

it in eight hours.

In

another year or two, something

less

than

five

hours will

be

routine.

To

do these things better -

at

less cost -and to make

the

eventual product more attractive to

the

buyer

is

the

constant aim of every form of business enterprise. Air

transportation

is

no exception.

Our

customer,

the

passenger, must be provided with what

he

wants -when

he

wants it.

We

have to display our full product -

we

have to make it attractive -

we

have to make

the

buying

process easy.

Looking

at

our product in

1940,

we

recognized

that

although

we

had made it attractive by providing new

aircraft

and

better in-flight service, there

was

little in the

offing to improve our reservations system.

Three-Part Problem

It

was

recognized

that

the

solution to

the

reservations

problem lay in something substantially different, or at

least more advanced, than anything which had served

the

industry through its early years of growth. After

reaching this conclusion

the

next step

was

to analyze

the

situation and define

the

problem. This

was

done

and

it

was

shortly concluded

that

making a reservation in-

volved three distinct actions or parts:

First, determining

the

availability of space; second,

modifying

the

inventory,

and

third,

the

recording of a

name.

It

was

further decided

that

Availability

and

In-

ventory Control were of

the

most immediate concern.

Availability

as

we use

the

term refers

to

the

status of

space on a particular flight. It answers

the

question:

Is

there space available, or on what flights

is

space avail-

able? Since our product

is

highly perishable

and

the

number of items we sell are almost infinite in number,

availability

is

highly dependent on an accurate

and

cur-

rent inventory control system.

Our

product

is

perishable because an empty seat on

a plane

that

has departed can never

be

reclaimed.

The

items we sell are infinite in number because each

boarding

point

on a trip on

the

fifth of

the

month

bears

little relation to

that

boarding

point

on a similar trip

on

the

sixth of

the

month, and

so

on.

The

seats cannot

be

used for identical purposes or substituted for one

10

another except in rare instances. Although hardly

the

rule,

it

is

not

unusual to receive bookings for a particular

trip years in

the

future.

Upon examination we found

that

there were two

general means of presenting availability information:

1.

The

Availability Book.

2.

The

Visual Display Board.

The

Availability Book,

as

the

name implies,

is

a book

or index in which

the

status of space on each leg of each

flight on each day

is

recorded. A leg,

as

we use

the

term,

refers to

that

portion of a flight between a scheduled

take-off and

the

next scheduled landing.

One

book can

be made physically accessible to a maximum of four

agents and

it

is

still used in small offices. J\1ultiple books

for use in larger offices had been tried and found want-

ing due to errors developing through delays or negligence

in posting from book to book.

This problem outweighed

the

advantage of having

the

information close to

the

agent and easily read,

as

well

as

the

advantage of being able to quickly insert new

pages to

give

effect to a revised order of departure caused

by

a schedule change.

Display Boards Tried

Poor experience in keeping several books in agreement

led to

the

use of a blackboard or visual display board so

that many agents might look

at

the

same source of in-

formation. This method likewise had limitations in

the

number of people

it

could conveniently serve. Clear

space to seat agents with a full view of

the

board

was

limited by

the

distance between columns in most build-

ings, usually about

22

feet by

22

feet.

The

use of multiple boards to overcome this difficulty

had

the

same disadvantage

as

multiple books.

In

addi-

tion, common visible displays presented serious growth

problems.

As

demand for services increased and

it

was

necessary

for more people to provide

service

to

the

customer,

the

.

size of each character displayed on

the

board had to be

increased so everyone could see it.

As

space became hard to obtain due to demand,

people who might otherwise

go

to

the

airport

and

take

the

first flight available began to make reservations. This

increased

the

calls to Reservations and required more

people to answer

the

telephones.

This same demand caused

the

manufacturer, in this

case

the

airline, to provide more planes to handle

the

pressure, thus increasing

the

amount of information to

be displayed. Even with

both

the

Availability Book and

the Visual Board, agents in ticket offices had to call

Reservations for information. And because of

the

limited

amount

of information

that

could be displayed

and seen in a large office, even

the

reservations agent

had to call a second party for some data.

COMPUTERS

and

AUTOMATION

August,

1957

Located in a room adjacent

to

American Airlines new reservations quarters, largest in

the

world,

at

Manhattan's

West

Side Airlines Terminal

is

the Magnetronic Reservisor, an improved version of an earlier model introduced

to industry by American in 1952. Built

to

the

airline's speCifications by Teleregister Corp., a subsidiary of Ogden

Corp."

the

new Reservisor provides

the

same instantaneous reservations information

as

its predecessor

but

in greater

detail and faster.

at

room and

the

racks surrounding the console

at

which

the

maintenance technician

is

seated, stores and releases information

to

the

inquiring reservations agent

at

the flick

of

a switch.

Naturally there has been a great deal of experimen-

tation with visual display boards.

There

are probably

as

many approaches

as

there are stations

that

use

the

boards.

Although slate and chalk are

the

most common ma-

terials used,

one

will see variations made of plastic,

ceramic coated steel, painted wood and

so

forth. Pre-

printed plaques using

both

colors and symbols are used

on some boards in an

attempt

to increase readability.

Many boards are made

to

raise and lower or to turn on

a central axis, all with a view toward making it easier

to

post information. .

Some attempts have been made to electrify these

boards

but

all

to

no avail because of

the

prohibitive cost.

Basic Requirements

After satisfying ourselves

that

reservations would

be

with

us

for some years in

the

future, and determining

COMPUTERS

and

AUTOMATION

for

August,

1957

the areas we would tackle first, namely Availability

and

Inventory Control, we

attempted

to outline

the

basic

requirements- of a system.

1.

We

felt

that

the

system should make our product

immediately available to

the

sales agent without

causing

undue

eyestrain or fatigue.

2.

It should enable

us

to record sales

and

cancella-

tions

as

they occur and keep an accurate running

inventory.

3.

It

should reduce our dependence on large, audi-

torium-like areas for future reservations offices,

and

by using regular communication facilities

make available to ticket offices, satellite offices or

to any point such

as

any room, all

the

informational

advantages one would have if seated in

the

reser-

vations office.

4.

The

input-output device, which we later called an

Agent Set, should retain a record of

the

last

11

operation until manually cleared or another trans-

action

was

entered.

It

should be easily operated by

right-handed or left-handed people and so simple

in operation

that

an agent could be trained in its

use in a matter of an hour or less.

5.

It

should automatically advise other stations, when

necessary, each time a given flight

is

sold out.

6.

It

should do all of

the

above economically, accur-

ately, and

be

capable of expansion.

Our

first approach naturally

was

to go

to

large

manufacturers and see whether thev had a device which

would meet our requirements, or

it"

they were interested

in

the

development of such a system. Interestingly

enough,

we

found

that

we

were in a field where little

had been done, that

is

the field of inventory control.

Any

number of organizations manufactured accounting

systems

but

there

was

a basic difference between these

systems and what we needed for inventory control.

In accounting, one person would have access to

hundreds or even thousands of accounts or records,

whereas in inventory control

the

situation

is

reversed

and ideally any or all salesmen should be able

to

get

at

the inventory for a specific item.

As

you can see, with

a perishable item like a seat on today's

five

o'clock flight

for

New York, it

is

necessary to handle the sale

as

quickly

as

possible. Conversely, upon receiving a can-

cellation it

is

necessary to return it to inventory im-

mediately so

that

it

may

be

resold.

Designed

Own

Equipment

It

soon became obvious

that

we

could

not

obtain a

piece of equipment off

the

shelf so to speak and manu-

facturers were

not

particularly interested in developing

new equipment to do

the

job.

We

did receive nuisance

quotations to develop such a system,

but

actually even

then there

was

little interest. Since

the

problem

was

not

likely to

be

solved unless we did something about it, we

decided to

attempt

the

design ourselves.

In

this case we

had

the

three advantages -knowing

the

problem,

not

knowing how it could

not

be solved, and a limited group

of

one person working on it.

We

were willing to listen

to any idea and examine its possibilities with an open

mind.

Some of our approaches were novel to

say

the

least.

One

early

attempt

was

as

much mechanical

as

electrical,

and its main purpose

was

to help visualize

the

problem.

In this solution we

~sed

vertical metal tubes to hold

marbles. Each tube representing a flight on a particular

day and each marble a seat. By means of an electric trip

at

the

bottom of each tube, marbles could be released

representing seats sold. Marbles could, be returned from

the

top to represent seats cancelled.

The

height of

In

a setting designed for comfort, speed and service, two American Airlines reservations agents

at

the

airline's

new reservations office

at

l\1anhattan's

West

Side Terminal provide

the

answers to

AA

customers. An agent's key

set, which

is

linked

to

the

Magnetronic Reservisor,

is

placed conveniently between

them

and other useful infor-

mation

is

quickly available on glass-enclosed charts

at

eye level.

12

COMPUTERS

and

AUTOMATION

for

August,

1957

marbles in

the

tube represented

the

number of seats

in inventory. Admittedly, this

was

not

the

machine

we

wanted

but

it

would work

and

it

served to give

us

a

better understanding of

the

problem.

Another idea

that

seemed

at

first to show promise

was

to use a bridge network with fixed value resistors repre-

senting each seat. You could

then

interpret

the

number

of seats by reading

the

voltage drop across

the

resistors.

This

was

all right

but

when we calculated

the

power

requirements we found

that

such system would con-

sume over

100

kilowatts. This

was

obviously

out

of line.

We

finally arrived

at

what may

be

called a cross-bar

system using relays. A matrix

was

designed which had

some similarity to the core memories of today, only in-

stead of cores

we

had jacks into which plugs were

manually inserted

~o

indicate open or closed. Across

the

top indicating each vertical column were

the

dates, and

along

the

side indicating

the

horizontal rows were the

trip legs.

Then

using

the

simplest of equipment

we

could check for continuity between vertical

and

hori-

lontal

lines which would indicate

that

a shorting plug

had been inserted meaning

that

the

flight

had

been

sold out.

A working model

was

built using parts immediately

at hand;

as

a matter of fact, much of

it

was

done in a

basement workshop. Upon completion,

the

model

was

operated before members of top management who

ap-

proved of

the

approach and set

up

a fund to further

explore

the

idea.

Our

luck seemed to change

at

this juncture.

The

Teleregister Corporation,

then

a subsidiary of

\\'

estern

Union,

was

contacted

and

after examining

the

operat-

ing model became interested

and

agreed to build a pilot

model for what

we

considered a reasonable price.

Pilot Model in 1946

This pilot model

was

installed in February,

1946,

at

Boston

and

was

used until

we

moved into our new

office last year. Although

the

equipment

was

designed

for use in

New

York, a last-minute change in plans made

it necessary to place

the

equipment in Boston. This

created a problem because

the

physical dimensions of

halls, doorways, etc., of

the

New York office were con-

sidered in fabricating equipment, and in Boston it

was

found

that

we

<;ould

not fit

the

equipment through the

stair well or in

the

elevator. It

was

necessary to obtain

a crane, remove an outside window on

the

third floor

of

the

building, and bring

the

equipment through this

opening. .

This first installation

was

designed strictly for avail-

ability.

It

had

no frills

but

was

sound from an engi-

neering

and

electrical standpoint. After

the

first year's

operation

we

evaluated results and found

that

the

station

was

carrying about

200

more passengers per day

with some

20

less people in

the

office. Unfortunately,

other changes had taken place in

the

office

at

the

same

time

and

we could

not

attribute all improvement to

the

Reservisor,

but

we

were able to prove conclusively

that

equipment of this type

was

economical and it had a

definite effect on revenue.

The

reception by

the

agents

was

just terrific,

In

a

very short time they had nicknamed

the

equipment

"Girly" because

it

told all.

COMPUTERS

and

A

UTOMA

TION

for

August,

1957

Shortly after

the

installation in

the

reservations office

we

placed remote connecting equipment in our Hotel

Statler ticket office, where its sales aspects were really

evident. .

It

(1946)

was

a war year - a time of priorities and

tight space.

\Ve

were continually accused of keeping

seats up our sleeve.

With

the

advent of

the

Reservisor,

where requests for space were made

and

answered by a

machine, this feeling completely disappeared. This, in

itself,

is

a very important contribution of machine

techniques.

With

the

availability problem well on

the

way

to

solution in Boston, our next problem

was

to handle

the

inventory. This problem

was

as

much economic

as

technical. An example of a technical approach

that

never paid off

was

an English-made system which

was

loaned to one airline in New York some years ago. This

system used rotary switches to do

the

counting. It

worked well enough

but

it

was

both

clumsy and costly.

Rotary Switch

Not

Practical

~he

ro~ry

switch, in its class,

is

basically a high speed

de,vIce

desIgn~d

for

m~ny

revolutions per second. Ap-

plIed to keepmg

the

mventory

on

a flight leg for a

month, this rotary switch would make less than one

revolution a

month

-a most uneconomic use of

the

device.

One

idea

that

was

pursued

was

to build a rotary

counter

out

of a screw and nut. A ratchet on

the

bottom

?f

the

scr~

would cause

it

to turn, thus moving

the

nut

m a vertIcal plane.

By

reading

the

height of

the

nut

electrically or manually, one could tell

the

number of

seats

on

the

plane. This approach like many others

was

\~orkab~e,

but

proved expensive from a manufacturing

viewpomt.

All of these proposals required systems

that

would

cost dollars per seat leg day, while our evaluation of the

project indicated

that

storage cost should be measured

in terms of about three cents per seat leg day.

About this time, considerable publicity

was

released

on

the

work of Dr. Howard

H.

Aiken of Harvard Uni-

versity. His progress with

the

magnetic drum

was

proving successful, and I believe

it

was

his work

as

much

as

any which spurred

the

engineers to explore

the

area

o~

a special purpose computer for

both

storing

and

countmg.

Magnetronic Reservisor Evolved

Subsequently, an unused

gri~ding

wheel

was

fitted

with a round aluminum billet and sprayed with an oxide

coating. A read/record head

was

mounted

next to this

improvised drum and connected to suitable electronic

circuitry which enabled

the

engineers to check

the

feasibility of this approach. It proved highly successful

and step by step

the

Magnetronic- Reservisor,

as

we

know

it

today, came into being.

Now, we cannot exactly compare this work with other

comput~r

",,:ork

of

t~e

time because our

intent

to apply

these pnncII?les to mventory control slightly changed

the

compleXIOn

of

the

problem.

We

required absolute

accuracy

and

22-hour-a-day operation, which

is

a tall

order even today. These requirements indicated a

slightly different design from

that

of

the

normal com-

puter.

13

For

example, although packing factors of

80

or more

to

the

inch were common

at

the

time, we packed

20

to

the

inch.

We

used dual drums -for

that

matter, dual

equipment throughout -and each transaction

was

completed in duplicate

and

compared throughout its

cycle

so

that

in the event an error

was

in

the

making

the

machine would throw

out

the

entire transaction

before

it

affected

the

inventory.

Each time a transaction

was

discarded

the

inventory

was

left in its original state and a red lamp signal sent

to

the

Agent Set originating

the

call

so

that

he might

reinstate his call.

At

the

same time, a teletype printer

printed

out

a record of

the

transaction which had been

discarded

so

that

the

maintenance group could analyze

the

situation.

The

fact

that

these and other safeguards

worked

is

evidenced by

the

99.8% up-time experienced

with

the

equipment.

One

problem

that

may be of particular interest

is

the

design of

the

Agent Set.

We

worried over this problem

for a considerable period of

time

examining every con-

ceivable approach.

Our

problem revolved about how to

put

in requests for information.

The

passenger can tell

the

sales agent where he wants to

go

and when he

wants to leave

but

he

can seldom give you

the

flight

number.

Secondly,

the

whole advantage of a reservations

system to American Airlines' lies in

the

ability

to

ac-

commodate a passenger on an earlier or later flight if

the

one of his choice

is

full. Expressed in terms of Agent

Set requirements, this means

that

the

equipment should

always offer an alternate or

at

least offer one if

the

specific . flight requested

is

not

available.

Using keys, buttons, dials and

so

forth to

put

in all

of

the

information needed

was

too time-consuming for

the

agent and tended to increase

the

physical size of

the

equipment.

We

tried mechanized versions of the desk

telephone index, drums with

the

information printed

on a removable paper roll, endless loops of

35

millimeter

film

and

slides of

the

same material which, of course,

necessitated having a projector

as

part of

the

Agent Set.

Each of these methods satisfied some problems

and

created others;

Destination Plate

Lastly, we thought of

the

Destination Plate which, in

effect,

was

an automatic encoding

and

decoding device,

eliminating

the

need for

the

agent to translate

the

passenger's request into machine or airline language.

To

reduce

the

number of destination plates needed

we

evolved .the scheme of a shutter switch which

al-

lowed

us

to view either of two lines of information on

the

plate by

the

flick of a switch.

The

system

was

finally agreed upon

and

in July,

1952,

the

first Magnetronic Reservisor went into operation in

New .York.

It

has proved to

be

an excellent, reliable

tooL Early fears of tube failure have proved unwar-

ranted."

When

we'installed

the

new, larger equipment

in

1956,

there were still many of

the

original comple-

ment

of tubes operating effectively in

the

old equipment

after more than four years of 24-hour-a-day service. I

should state here

that

two hours a 'day are given to pre-

ventive maintenance.

14

Coincident with

the

work

on

the

Reservisor we were

requested to look into

the

problem of disseminating

arnval

and

departure information. I

don't

know why

we

did

not

see

the

similarity to

the

availability problem

immediately,

but

our first approach

was

to mechanize

the

function

as

it

was

then

performed. This consisted

of remotely controlled indicators which would take

the

place of

the

blackboard or other means of presenting

the

information. A brief look

at

the

final design indi-

cated

that

it

would do

the

job,

but

at

a cost

that

we

could

not

-justify.

We

dropped

the

project temporarily,

but

kept

it

in

the

back of our minds.

One

balmy summer day it

occurred

to

us

that

we

could store

the

information in

the

Reservisor and read it from a fixed display by means

of

the

leg-indicating lights.

Today, in addition to availability and inventory con-

trol,

the

Reservisor also dispenses flight information.

One

Vast Network

American Airlines now has advanced models of

the

original Availability Reservisor located in Chicago,

Boston

and

Washington.

The

New

York counting

Reservisor handles

the

entire metropolitan area and

is

remotely connected with Buffalo. Gradually, all

the

large stations will

be

joined together into one vast net-

work.

We

will retain Availability equipment in large

cities

and

route calls from Agent Sets

to

these local

units for availability and information. Sell and cancel

calls will be routed to one or more central inventory

control units which will, in turn, update

the

local Avail-

ability units.

This seems to be

the

general pattern

that

is

shaping

up

with all

the

airlines, and

it

is

only a question of time

when

we

will interconnect our services.

As

I stated

at

the

beginning, we found three major

areas: Availability of

the

product, inventory of

the

product,

and

handling of

the

name record or

the

physical record of

the

transaction. I have outlined how

we approached and solved

the

first two. During

the

last few years

we

have been working on

the

solution of

the

latter problem,

that

is

the

handling of

the

name

record. A pilot model of

the

equipment to handle this

situation

was

developed jointly with

IBM

and

is

presently in use in Buffalo.

It

is

known

as

a Data

Organizing Translator.

It

reads

the

keypunched reservations record, decides

whether one or more messages need be sent to other

stations, if messages should

be

sent,

it

decides whether

the

stations are on American Airlines or another airline,

and, based upon this decision,

it

determines

the

Code

Directing Characters

that

should prefix each message

in order to reach its destination.

Foresees Many Uses

It

then

prepares

the

message organizing

the

text for

each addressee depending on

that

city's position in

the

itinerary. A local electric typewriter can produce a copy

of each message sent. An additional local typewriter can

produce a list of all transactions in any desired category,

such

as

sales on other airlines, sales on flights ending or

beginning in

2,

etc. A punched 5 level tape

is

produced

THE

ROLE OF 'COMPUTERS

IN

HIGH

SCHOOL SCIENCE EDUCATION

I:

THE

ASSOCIATION

FOR

COMPUTING

MACHINERY

and

HIGH

SCHOOL

SCIENCE

EDUCATION

George E. Forsythe

Numerical Analysis Research,

University of California

at

Los Angeles

(A

memorandum from

the

chairman of

the

Education Committee of

the

Association for Computing

Machinery, addressed

to

"approximately

100

persons who have expressed an interest

in

the

subject")

T

HE

Association for Computing Machinery

is

an

international society of scientists interested in

the

design, manufacture,

and

use of automatic com-

puting machinery.

The

author

is

chairman of

the

Education

Committee

of this Association.

The

purpose

of this memorandum

is

to

let

you know of my interest,

and

that

of

the

Education Committee, in

the

problems

of high school mathematics and science education.

The

opinions expressed here are those of

the

author and

not

necessarily those of

the

Association's Education

Committee. Your comments will be appreciated.

At

the

national meeting of

the

Association in

Houston, Texas, June

19-21,

1957,

the

Council of

the

Association passed

the

following resolution:

"The

Council of

the

Association for Computing Machinery

notes that bettcr education in science and mathematics in the

pnmary and secondary schools cannot be expccted without higher

salaries for teachers of science and mathematics, at least.

The

Council urges members of

the

Association, if they see fit, to work

for such higher salaries in their own communities.

The

Council

also urges members of the Association, if they see fit, to make

their time and talents available to the schools of their com-

munities for collateral educational activities."

This resolution speaks for itself.

The

phrase "collateral

.....

activities" expresses my feeling

that

people in

industry are rarely equipped to take up classroom teach-

ing,

but

that

they can make a contribution if they will

volunteer for mathematics clubs, assembly programs,

computer visits, or for any number of useful extra-

curricular activities to promote interest in careers in

science and engineering.

Several of

us

in

the

Association have had experience

in speaking

to

school groups and teachers.

We

are

aware of

the

interesting, important, and reasonably well

paid positions in science

and

engineering, and are

anxious to let high school and junior high school stu-

dents

and

their teachers know about these careers.

We

know

that

the

number of large scale digital computing

machines

is

going to

be

enormous. (Over

700

had

been

installed by December

1956,

with over

2200

on order

at

that

time.

Within

five

years, I estimate

that

around

5000

computers will

be

installed.)

Each of these machines can be expected to require

at

least

10

mathematically trained persons

at

some level

to assist in its use. This total of

50,000

jobs compares

with today's total of less

than

12,000

members in all of

our mathematical societies combined. Obviously many

more people will

be

needed.

The

basic source can only

COMPUTERS

and

AUTOMATION

for

August, 1957

be mathematically educated high school students.

In

addition to positions dealing directly with computers,

an even larger number of related positions in engineer-

ing and business will be affected materially by contact

with

the

computing centers.

Apparently most high school students -even bright

ones -are pretty cold to careers in science. (See Ben-

jamin Fine's article, "New York Times", 9 September

1956,

section I, p.

76).

Surely part of

the

cure

is

for

enthusiastic speakers and teachers to get young students

fired up with

the

inherent fascination and just plain

FUN

of science.

Automatic computers are exceptionally well suited for

this purpose, because of their ultimate simplicity. Digital

computers can only add, subtract, multiply,

and

divide,

and

the

junior high school

student

already knows these

operations. Many of

the

further problems which arise

in practical computation can

be

understood and appre-

ciated by a bright

ninth

grader. I know of no other field

of mathematical science where a high school

stuaent

can thus come to grips with important and live problems

on the. borders of knowledge.

Of

course,

the

staffing of computer laboratories

is

only

one aspect of

the

broad national problem of science

~nd

engineering education. ,

.'

, i

Much

routine clerical work can be done by

machin~

right now, and many clerical positions will gradually

cease to exist,

as

computers take over these roles. I con-

sider this to be a Computer Revolution comparable to

the

Industrial Revolution, and therefore feel

that

ordinary school students -

and

not

just future scientists

and machine operators -must be made aware of

the

general nature of these machines.

The

success of our impact on education will mainly

depend on

the

supply of teaching materials which

we

can make available to

the

schools.

It

is

therefore very

important for qualified people to design computer kits

and

other materials suitable for classroom

and

after-

hours use. This

is

the

conclusion of Richard

W.

Mel-

ville, chairman of

the

Committee on High School

Science Education of

the

Joint

Computer

Committee,

as

expressed in his informative report in "Education

and

Computers", Part

2,

of

the

January,

1957,

issue of

Computers

and

Automation.

I believe

that

our schools cannot possibly obtain

enough good science teachers at--the prevailing salary

scales, in

the

face of

the

current competition for

scientists. However, many teachers are encouraged to

15

remain in teaching by interesting and remunerative

summer work.

Our

committee therefore hopes

to

give

publicity to such plans for sharing personnel by industry

and schools

as

have been inaugurated by

the

Hughes

Aircraft Co. (Culver City, Calif.) and Arthur

D.

Little,

Inc. (Cambridge, Mass.)

II. A

THREE-PART

APPROACH

TO

SOLVING

THE

PROBLEM

w.

Eugene Ferguson

Head, Mathematics Department

Newton High School, Newtonville, Mass.

(Read during a panel discussion on

"The

Role of Computers in High School Science Education",

at

the

meeting of

the

Association for Computing Machinery in Houston, Texas, June 20, 1957.)

T

HE

role of computers in high school science

education

is

still an unknown quantity. I hope

that

during this discussion today some of

the

most

promising ideas for

the

introduction of computer edu-

cation in

the

high school will be brought out.

As

one reads

the

"help wanted" columns today (at

least in the Boston area), he

is

struck by

the

heavy

demand for computer personnel, from

the

design engi-

neer on down to

the

programmer, coder, and computer

operator.

If

the

supply

is

to catch up with

the

demand,

I believe there must be some computer education

de-

veloped for

the

high school. I have singled

out

the

computing field,

but

I would hasten to add

that

this

is

only one small area in

the

larger field of

the

sciences.

I shall attack this problem from three angles:

First: Teacher shortage, and its relation to programs in

high school mathematics and science, and the

shortage of well-trained scientists.

Second:

The

high school curriculum in relation to needs

for scientific personnel and computer people.

Third: How industry can help in high school science

education.

It

is

probably a safe assumption

that

we

need more

and better trained scientists, engineers, and computer

personnel.

To

insure an adequate supply of scientists

the

first thing

that

must happen

is

that

the

high schools

must

be

adequately staffed with qualified people in

their mathematics and science departments. I

say

high

schools,

but

I would like to repeat

the

same statement

for junior high school mathematics and science depart-

ments, and even on down to

the

elementary schools.

The

junior and senior high school

is

where

the

initial

stages of excitement in science start, and young people

when excited need adequately trained teacbers guiding

them.

Inadequate Salaries

The

major difficulty in getting adequately qualified

and competent teaching personnel in the mathematics

and science classes today can be summed up in two

words, inadequate salaries. How can

we

hope to keep

a staff of adequately trained teachers if their salary

range

is

so

low

that

it

is

impossible for them to make

a living without having a second job after school hours?

These conditions exist today almost everywhere, even

among some of

the

recognized top public schools in the

natioh~

---;

'-I

,-

-

16

The

developments in science and mathematics today

are moving

at

such a pace

that

the

training received by

teachers a few years ago

is

woefully inadequate for

to day's modern classroom in mathematics and science.

I am head of

the

mathematics department in a large

high school; and in order for my teachers to keep pace

with modern developments, they have to go back to

school from time to time or

at

least spend their sum-

mers studying, and

not

do odd jobs to eke

out

a living.

The

grants by

the

National Science Foundation for

attending summer institutes are a great help. I also

believe industry could employ some teachers for sum-

mer jobs in their computing and science sections, and

bring them up to date with needs in mathematics and

science. I believe it

is

still true that teachers have a

tremendous influence on

the

likes and dislikes of

students for various subjects. Many potential careers in

mathematics and science are killed by inadequately

prepared, unhappy, and underpaid school teachers.

Up

until now we have been able to staff our own classrooms

with dedicated teachers who have a missionary zeal and

are willing to make the monetary sacrifice.

But

the

question asked by many teachers today

is:

"Why

should

I sacrifice money for a college education for my children

by going into

the

teaching profession?"

How would increasing salaries alleviate

the

teacher

shortage?

If

I can believe some of

the

things I hear,

there are literally thousands of people qualified

to

teach

mathematics and science who are doing fringe engi-

neering jobs, and who would love

to

be

back in

the

mathematics and science classroom, if they could only

make a living at it! (I

say

back into

the

classroom, for

many were former teachers. Many others, though, would

be teaching for

the

first time.) Teachers have been

fighting for better salaries for years. Many of

us

quit

the field for a while,

but

now we are back again battling

for education. I am chairman of

the

salary policies

committee of our Teachers Federation, and I am con-

vinced that the parents and public

in

general must come

to our rescue.

I would like to suggest

that

the Association for

Computing Machinery go on record

as

favoring sub-

stantially increased salaries for teachers and

that

each

member do something about it

in

his own school com-

munity. I believe your voices will

be

heard and heeded.

An

adequately trained and adequately paid teaching

staff can turn

out

the

potential scientists we need.

COMPUTERS

and

A

UTOMA

TION

for

August,

1957

In

1954

some of my senior girls

at

Connecticut Col-

lege for

Women

with an

AB

degree, with major in

mathematics or science, took jobs in

the

computing

field

at

about $4000 (several dollars more than I

was

making). Today, three years later, they are

at

about

$6000. I have teachers with master's degrees on my staff

making much less than $6000 after more than

12

year's

experience!

Why

should smart mathematics students

go

into teaching when such low salaries are now being

paid to teachers?

You may feel

that

I have dwelt on salaries too long,

but

what I have to

say

in a

moment

about an adequate

curriculum for the high school

goes

right back to money

to buy teachers and give them free time to think

and

devise new programs in

the

light of present day

de-

velopments. 1\1uch of this free time

is

to be found only

during

the

summer months. Teaching, well done today,

is

a full-time, year-long job.

It has been suggested by many people

that

we

raise

salaries of mathematics and science teachers above

the

regular salary schedule,

say,

$1000

or more depending

on

the

salary schedule. I have not supported

that

sort

of thing

so

far because teachers need all salaries raised.

Dr. Forsythe has pointed

out

to me

that

in order

to

keep qualified mathematics and science teachers in

the

classrooms maybe

we

must have a crash program like

this and gradually bring

the

other teachers' salaries

up

to it, since to make large jumps in all salaries would

make

the

cost prohibitive.

This argument has merit,

but

I am still worried about

teacher morale. Yet, private schools and colleges do this

sort of thing all

the

time, paying' attention to

the

law

of supply and demand and maybe this needs to

be

ex-

amined more carefully

as

a distinct possibility.

But

I

am also afraid this would be used

as

an excuse to keep

other salaries too low.

We

need well paid teachers in

all fields.

Strong Curriculmn Needed

On

to my second point of attack:

The

high school

curriculum in relation to scientific personnel and com-

puter needs.

I feel

that

a strong mathematics and science curricu-

lum in high school

is

basic to

the

training of future

scientists. I also believe

that

good high school science

courses must

be

available, too. I

don't

want to debate

which one

is

more basic,

but

please

let

me outline

the

high school mathematics curriculum

that

I believe

is

absol,utely necessary

if

we

are to meet

the

challenge of

modern society

and

the

shortage of well-trained per-

sonnel in all fields -

not

just science alone.

For

we need

social scientists

and

people in

the

humanities

that

really

know

and

appreciate mathematics and science.

As

you

might suspect, I will be outlining

the

mathematics

program

at

Newton High School. It consists of four

levels:

First level:

There

must

be

an advanced track, an ad-

vanced placement program for those students who are

the top thinkers in mathematics.

The

program

is

the

one outlined in

the

Advanced Placement Bulletin of

the

College Entrance Examination Board.

It

covers

elementary, intermediate,

and

advanced algebra, plane

and solid geometry

and

elements of analytic geometry;

COMPUTERS

and

AUTOMATION

for

August,

1957

and it

is

topped off in

the

senior year by a first year

college course in differential and integral calculus.

Teachers of

the

caliber required to teach these stu-

dents are not available in many schools today because

the

school committees and school boards will

not

pay

the

price to get them. This

is

not

necessarily

the

school

board's fault, because

the

townspeople

m~v

not

have

convinced

the

board

that

they want a first class school

system.

Second level:

There

must be a second track, a

se-

quence of four years of standard college preparatory

mathematics. It covers:

9th

grade spent

on

elementary

algebra; 10th and 11th grades spent in studying plane

and solid geometry, and intermediate algebra; in

the

12th grade or senior year, advanced algebra, trigo-

nometry, introduction to analytic geometry, and some

calculus _ of polynomials.

Third

level:

There

must be another track for slower

students of mathematics, late bloomers

so

to speak. It

covers:

9th

grade, elementary algebra; 10th grade,

geometry;

lIth

grade, intermediate algebra;

and

in

the

12th grade, review of arithmetic, algebra,

and

geometry,

and one-half year of trigonometry. This course

is

for

boys and girls going to technical institutes

and

also to

some of

the

less

demanding colleges.

Fourth level:

There

must

be

a general mathematics

sequence of three years study for those boys

and

girls

(and there are some) who find or will find

that

all of

the

above three tracks are more

than

they can handle.

To

keep a qualified staff of

16

to ] 8 people to handle

this program for a high school of 2000 students costs

money

and

is

going to cost more money.

One

needs a

master's degree in mathematics to handle

the

advanced

program

as

outlined above.

This program looks good,

but

it

still isn't good enough

for this modern day world.

At

the

invitation of Prof.

Max Beberman, project director of

the

University of

Illinois

Committee

on School Mathematics, Newton

is

entering their program of Secondary School Mathe-

matics in four classes in two of Newton's

five

junior high

schools.

The

Project Staff has completely rewritten high

school mathematics, putting in

as

much modern mathe-

matics,

as

can

be

made understandable to high school

students. Revisions of

the

text materials are constantly

going on in

the

light of experience gained in teaching

the

materials.

I think this

is

one of

the

most. promising develop-

ments in secondary school mathematics under

way

at

the

present time.

The

old traditional high school

mathematics

is

not

nearly

as

exciting

as

this new pro-

gram. Also it does

not

get to

the

so-called modern

mathematical concepts

that

are useful in

the

computing

field nearly

so

quickly. Here again we need money to

pay

the

salaries of

the

people who have obtained or

will obtain such training in modern mathematics.

Industry Assistance

Now for my third angle of attack: How can industry

help in high school science education?

We,

in

the

secondary schools, need some elementary

units on computers which

we

as

mathematics teachers

can understand

and

bring in

at

the

proper

moment

during

the

various high school mathematics courses.

17

There

are qualified.'>Icdii1pu'ter

p~rsonnel

that

could

write these units, if they would take

the

time to do it.

You people could invite a science and a mathematics

teacher in your own community to have a look

at

some

of

the

things going on in your industry and gently get

them excited about it. This

is

a delicate problem I

know,

but

it

can be done if you

don't

make

the

teacher

feel uncomfortable

and

inferior because he doesn't

know about these things. Here

is

where a summer job

with an industry would payoff.

In

Newton, our mathematics curriculum

is

pretty full,

but

school

is

out

at

2:30;

so

I am thinking seriously of

.a

seminar

at

2:45

sponsored by

the

Mathematics Club

featuring a person from

the

computing field armed with

suitable text materials mimeographed for each member

of

the

seminar, and also any hardware

that

can

be

easily

transported, and finally a tour of some computer in-

stallation. For this program to

be

successful, I will need

at

least a key math teacher who

is

willing to learn some-

thing of

the

computer field. I will expect to be in on the

show

at

first,

but

it

can't

be

a one-man show over the

years.

The

proposal

that

industry supply an engineer to take

over mathematics or science classes to alleviate the

teacher shortage problem can work very well

at

the

college level,

but

I have serious doubts about

its

feasi-

bility

at

the

high school level.

For

there

is

much more

to teaching in high school than just going in and

meeting a class.

The

administrative details would have

to double up on regular teachers' shoulders;

then

we

are in real trouble.

The

general feeling

that

I have found to this proposal

has been very negative. I still believe

the

best

way

for

industry to win

the

confidence of

the

teacher and really

help

him

is

through summer employment. Part of

the

expense could surely be written off by

the

company

as

expense attributable to public relations and community

education.

In

talking this problem over with Dr. Navez, head of

our Science Department,

he

suggested

that

we

needed

simple computer kits with complete drawings

and

in-

structions for building a simple computing machine.

Could

it

be

that

industry has discarded hardware

that

could be given to

the

high school science department,

maybe for a small

fee?

Schools have been reluctant to set aside money for

teachers to attend professional conferences.

The

problem of substitute teachers and their pay

is

also part

of

the

picture. Industry could

be

of great help here by

offering to pick up

the

tab for part of

the

expenses

and

furnishing an engineer to substitute for

the

teacher.

This has been done in several areas already.

As

an

example, Arthur D. Little, Inc., Cambridge, Mass., paid

my travel expenses to this conference and

the

Newton

Public School system

is

paying

the

other expenses.

Questions

I have had my say now and would like to ask some

questions.

Will

someone please outline briefly for me

some of

the

teaching units in

the

computing field

that

they think should be taught to high school students?

By

a teaching unit I mean a body of knowledge, facts,

material, etc.,

that

is

organized in a unit for teaching

purposes. '

I have a feeling

that

we on

the

high school level have

a responsibility for

the

general education of students

about

the

computing industry. I

don't

think

-we

can

discharge this responsibility effectively unless

the

com-

puting industry supplies

us

with

the

proper materials

and teaching units for our own education

as

well

as

the

students'. I personally am mostly interested in teaching

units suitable for mathematics classes,

but

if vou have

ideas about science units, I would like to

p~ss

them

along.

Another question: During August I will

be

thinking

and trying to develop some teaching materials in mathe-

matics

that

can

be

used with large groups of

100

or

more, using a 12xl2 screen, projectors, overhead pro-

jectors, overlays, etc. Could a

unit

lasting one or more

50

minute periods be developed for general education

about computers

that

would be worth

the

time

and

effort involved?

My

friends know

me

as

an eternal optimist,

but

my

experience during

the

last two years trying to find

qualified teachers

to

teach mathematics for sub-pro-

fessional salaries has

me

deeply concerned about our

future supply of well-qualified scientists.

(A

summary of a talk presented

as

part of a panel discussion

on

"The

Role of Computers in High School Science

Education"

at

the

meeting of

the

Association for

Computing

Machinery, Houston, Texas, June

20,

1957.)

T

HE

topic of this panel discussion

is

indeed provo-

cative! Because of

the

newness of computer tech-

nology, we suspect a paucity of computer material

in high school science education. Yet, because of

the

dearth of time now available for fundamental science

18

education we suspect little desire to further overload

the

curriculum. From another viewpoint, however, we

recognize

the

impact of this new technology

as

a tool

in science, in business,

and

as

an important part of our

scientific culture

"to

know about." Postulating, then,

COMPUTERS

and

AUTOMATION

for

August,

1957

that

computer technology will have a role to play in

high school education, let

us

examine how it might

be

played.

To

be

of inspirational or technical help to the student,

the

teacher must himself have some appreciation

and

u~derstanding

of computers. This means

that

years after

hIs

formal college preparation for science or mathematics

teaching

the

teacher must knuckle down

to

master

the

new knowledge of computers. This

is

but

indicative of

the

practice of life-long learning

that

high school

teache~s

must engage in merely to keep abreast.

The

followmg paragraphs briefly indicate examples of indus-

try-school personnel exchanges

as

a mechanism for such

cont~mporization,

and they dwell more fully on a

speCIfic

Hughes computer seminar experience with high

school teachers.

Personnel Exchanges Between

School

and

Industry

The

number of summer jobs in industry for high

school teachers of science

and

mathematics

is

increasing

each year.

To

serve

the

needs mentioned earlier such

job~

should really

be

positions, professional

positi~ns

in

w~Ich

th~

teacher has an opportunity to participate in

~IS

techmcal field.

~ne

example of this kind of activity

IS

~he

Arthur

D.

LIttle program near Boston, which

is

akm

to

certain cooperative work-study programs for col-

lege students. Two teachers hold one job in

the

Arthur

D.

Little plant in sequence, each teaching one semester

of

the

year.

In

Los Angeles industry, chiefly aeronautical

and

elec-

tronic research and development, about

100

professional

positions in some

15

companies are available this sum-

mer for teachers to engage in their technical specialty.

At Hughes,

19

teachers, nine back for

the

second sum-

mer, will

be

assigned to professional positions in

re-

search and development. Examples of technical areas

are ferrite physics, gaseous electron tubes, digital com-

puters, analog computation, network theory. Com-

petencies embrace mathematics, physics and chemistry.

T.he teachers are paid

at

their school system rate and are

hIred

fo~

the

summer only; additionally they receive

salary pomts toward upgrading from their school system.

The

teachers, their supervisors and

both

school svstem

and Hughes

o~cia.ls

attest to

the

value of the exper'ience,

and

the

practIce

IS

spreading to other companies

and

school districts in

the

Los Angeles area.

Other

personnel exchanges include summer work in

~ndustry

for students

and

visiting lecturers from industry

m

the

school classroom. A high school

student

tea~

successfully tackled a Washington, D. C., civil defense

problem last summer

at

the

Operations Research Office

of John

H~pkins

University; and

the

project will

be

repeated

thIS

summer. Hughes has initiated a similar.

st~dent

project this summer, selecting in cooperation

WIth

several adjoining school districts a dozen outstand-

ing

s~u?ents

having

a.t

least

one

semester of high school

remammg.

One

ant!cipated outcome

is

the

catalytic

efIe~t

of

the

enthUSIasm of

the

students returning to

theIr schools and classmates in

the

fall. '

Scientists and engineers from industry have been

called on for some

time

and

in many locales to speak

to

COMPUTERS

and

AUTOMATION

for

August, 1957

science clubs, assemblies, career days,

and

Parent

Teacher Association meetings; they have given guest

lectures on technical topics in

the

classroom. A program

having considerable educational

depth

has now been

conducted by Hughes for a calendar year.

It

consists of

an organized team of four or

five

Hughes technical per-

sonnel to give a series of contemporary lecture-demon-

strations stemming from

the

professional experiences

of

the

panel and integrated with

the

course text and

syllabus. This last year some

22

technical staff members

comprised

five

lecture teams in Phvsics I and

II

Chem-

.

,,'

Istry I and

II

and

mathematics, participating in four

high schools.

The

very favorable results justify continuation of this

program and its expansion to

other

companies

and

schools. Needless-to-say some of

the

application ma-

terial of these lecture-demonstrations can include com-

puter technology -although such

is

not

the sole prime

objective.

Experience with a

Computer

Seminar for Teachers

During summer 1956,

the

10

teachers in the Hughes

program devoted

about

20

percent of their

time

to

orientation lectures and

to

get-togethers of their own

group to relate their work experiences to their subse-

quent

teaching activities.

Near

the

close of

the

summer

it

was

decided to reassemble

the

group occasionall;

throughout

the

fall to provide follow-through into

the

classes. This follow-through took

the

form of a series

of

five

8-hour Saturdays, September to December, and was

a seminar or workshop devoted to "arithmetic com-

puters." This topic resulted from interest in an earlier

orientation talk on computers

and

from the fact

that

seven of

the

teachers were in mathematics.

Of

interest at this

point

is

the

concentration on digital

rather

than

analog computers because of

the

dearth

of

appreciation of calculus! Brief background talks

and

demonstrations were given on

the

REAC

mechanical

Differential Analyzer,

and

EASE, while

~ore

serious

attention

was

given to

IBM

computers,

the

SW

AC

computer, and a successor to

the

"Geniac" computer kit.

Considerable time

was

spent

on

coding a problem

for

the

SW

AC

and

then

on running through

the

solu-

tion so

that

the

teachers would

be

forced

to

think

hard

about

the

meaning of arithmetic operations -all in

trying to understand

what

the

machine would do.

The

modified "Geniac"

was

a plugboard with toggles and

multiple-deck, multiple-position switches (and lights)r

such

that

a number of

the

classical logic games could

be

implemented.

Of

great interest to

the

teachers

was

the

~eth~dology

for expressing symbolically

the

logic of a

SItuatIOn, such

as

the

automobile turning indicator,

the

translation of this into a diagram, and finally implemen-

tation by simple circuitry.

Assimilating this new knowledge

was

rough for

the

teachers

but

they "sweat

it

out"

and, in addition, pro-

duced an excellent manuscript for

the

benefit of

their

fellow teachers.

Under

title of

"An

title, organization, address, main interests, year of birth,

college or last school, year of entry into

The

remaining entries were brief entries containing only

name and address (sometimes also organization).

BOOKS and OTHER PUBLICATIONS

(List published in "Computers and Automation", Vol. 6,

No.8,

August, 1957)

WE publish here citations and brief reviews of books,

articles, papers, and other publications which have

a significant relation to computers, data processing, and

automation, and which have come to our attention.

We

shall be glad to report other information in future lists

if a review copy

is

sent to

us.

The

plan of each entry

is:

author or editor / title / publisher or issuer / date,

publication process, number of pages, price or its equiva-

lent / comments.

If

you write to a publisher or issuer,

we

would appreciate your mentioning Computers and

Automation. In the case of a review with a by-line,

the

opinions expressed are those of the reviewer and not

necessarily the

views

of Computers

and

Automation.

The

following

reviews

are by Ned Chapin, Menlo Park, Calif.

Rubinoff, l\tlorris, and Ralph

H.

Nov. 1956/l\tlcGraw-Hill Publishing Co. Inc., 330

W.

42

St., New York 36, N. Y./1956, printed, $4.00 per year.

The

authors classify input and output equipment for automatic

computers in terms of the

use

made of the computer. Delayed-

time use, real-time use, and computer-control-and-maintenance

use

are the three computer-use situations contemplated.

In

delayed-

time

use,

equipment capable of handling alphameric symbols

is

most widely used. Two examples are punched card equipment

and line printers.

In

real-time

use,

high speed

is

necessary and communication

must be established between the thing controlled and the auto-

matic computer. Analog-to-digital converters, digital-to-analog

converters, control devices, 'and visual displays, such

as

on CRT's,

are

common.

The

input and output equipment used with auto-

matic computers in real-time

uses

broadly overlaps those used

in

delayed-ti~e

uses.

In control and maintenance by means of automatic computer,

the input and output equipment

is

subject to qualitatively and

quantitatively different requirements than in either real-time or

delayed-time

uses.

Terse, rapid, "high entropy" communication

devices are needed.

The

authors

feel

that present input and

output equipment in this area of use

lags

further behind needs

than

it

lags in the other two areas.

The

authors devote much of the article to a discussion of thc

logical dcsign of magnetic tape-handling equipment.

Berkeley, Edmund C., and Lawrence Wainwright/"Computers:

Their Operation and Applications," 366 pp./Reinhold Publish-

ing Corp., New York, N. Y./1956, printed, $8.00.

The

contents of this readable book lists rather well what the

book covers.

The

book

is

divided into seven sections whose titles

are: 1 - Machines that Handle Information; 2 - Automatic

Digital Computer Machines; 3 - Automatic Analog' Computing

Machines; 4 - Other Types of Automatic Computing Machines;

5 - Miniature Computers and Their Use

in

Training; 6 - Some

Large Scale Digital Computers; and 7 - Applications of Auto-

matic Computing Machines.

The

first two sections consisting of 74 pages are introductory

in

nature and introduce the basic vocabulary of the field. Included

in

these sections are some reprints of reference material from

"Computers and Automation."

Section three of the book

is

primarily the work of Lawrence

Wainwright. This section introduces analog computers

by

means

of mechanical analogies. This section

is

85

pages long and con-

tains a number of illustrations and diagrams.

Section four

is

very brief and consists of only eight pages

which are primarily devoted to listings of equipment, type, and

components.

24

Section

five

(40 pages in length) dealing with miniature com-

puters

is

primarily devoted to "Simon."

Section

six

on Large Scale Digital Computers discusses in some

detail the following machines: the UNIVAC I and II; IBM

701,

702, 704, 705; and ERA

1103

(UNIVAC Scientific).

On

page

216,

the author describes the speed of

UNIVAC

I in terms of

"the

average number of three-address operations." This

gives

the

impression that the UNIVAC

is

a three-address machine, which

it

is

not.

The

UNIVAC

is

a one-address machine with two

instructions per word.

To

be consistent, the author should have

quoted the speeds for the other machines in comparable terms

but

he did not.

It

is

also noteworthy that over half of the discussion of this

section

six

is

devoted to UNIVAC I and II and that the other

machines combined are relegated to less than

50

percent of

the

space.

The

discussion on each point of the other machines is

much

less

thorough and complete than in the

case

of UNIVAC

I and II.

Section seven, devoted to applications, covers

58

pages. This

section which

is

the work of both Berkeley and Wainwright dis-

r cusses briefly the following topics:

"Whose

work can automatic

computers

do?

what people may buy automatic computers?

the

attitudes of prospective buyers toward automatic computing ma-

chines; applications of automatic computing machines in business;

military applications of analog computers; applications of auto-

matic computing machines to other fields; recognizing areas for

automatic computing machine applications."

From page

305

to the end of the book, will be found reference

information such

as

a list of organizations in the automatic com-

puter .and automatic instruments field, lists of publications, lists

of books, a good

glossary

reprinted from Computers and Auto-

mation, and an index to the book.

This

is

a glossary of electronic terms published

by

the Elec-

tronics Department of the Atvidabergs Industries in Stockholm.

All

definitions of terms are in Swedish,

but

both the German

and English translations of the terms themselves are provided.

The

glossary

is

good; it indicates the progress in interest and

use

of electronics in Sweden -the interest certainly appears

similar to our own in this country, and fully

as

advanced.

The

introduction states the names of members of Atvidabergs

Industries and coworkers in other companies such

as

Svenska

Aeroplan who have helped compile the glossary; it

also

gives

credit for certain definitions, etc., to the January and October,

1956,

issues

of Computers and Automation and the September,

1956, Proceedings of the IRE. Pages

23

and 24 contain a trans-

lation of English digital computer terms into their Swedish

equivalents, arranged in the alphabetic order of the English terms.

INDUSTRY NEWS NOTES

Ed

Burnett

New York, N.

Y.

RAMO-WOOLDRIDGE

CORP.,

Los Angeles, Calif.,

has announced development of a new, compact ad-

vanced digital control computer to provide fully auto-

matic control for industrial process plants.

The

new

computer, known

as

the

RW-300, can automatically

read process instruments, perform

the

computations

necessary to relate these readings to process objectives,

determine control actions

that

will result in best

plant

operation, and actuate process mechanisms or adjust set

points on supervised control loops.

PHOTRONIX,

Columbus, Ohio,

is

a new organi-

zation formed

to

apply electronic computing methods

in

the

interpretation of aerial photographs for engi-

neering purposes.

The

processes used reportedly save

up

to

60

percent of

the

time required

to

produce high-

way plans, and eliminate sub-professional drudgery by

integrating

the

sciences of aerial survey, photogram-

metry,

and

electronic computing.

ELECTRO-DATA

division of Burroughs Corporation,

Pasadena, Calif., in cooperation with

the

atomic energy

division of

AMERICAN-STANDARD

CORP.,

is

pre-

senting a new mathematical approach

to

the

design of

nuclear reactors. Known

as

DMl\1 (Diffusion Multi-

group Multiregion), this complex code involves

the

utilization of a computer

to

predict

the

point

at

which

a reactor will generate enough controlled power to sus-

tain itself. By utilizing

the

40,800 digit capacity of

the

computer's memory drum,

DMM

is

reportedly able

to

permit prediction of operation

at

various energy levels

involving elastic and inelastic scattering of atomic forces

in planar, cylindrical, and spherical reactors. Among

the

organizations using

the

DMM

code are

the

Nuclear

Development Corp., American Machine & Foundry

Co., and Babcock & Wilcox.

METROPOLITAN-VICKERS

ELECTRICAL,

Ltd.,

London, England, has developed a computer system

to

test strains undergone by aircraft components under

high temperature created by extremely high speeds.

The

computer equipment provides a coordinated system for

carrying

out

simulated tests while retaining

the

flexibility

required

to

meet

varying requirements of different users.

PACKARD-BELL

ELECTRONICS

CORP.,

Los An-

geles, Calif., has received a research

and

development

contract from

the

Army for a high speed digital com-

puter.

The

new equipment, when completed,

is

to

be

installed

at

the

U.

S.

Army

Computation

Center, Red-

stone Arsenal, Huntsville, Ala.

GOODYEAR

AIRCRAFT

CORP.,

Akron, Ohio, has

added a new analog computer,

the

GEDA

A-14,

which

is

expected

to

have far-reaching applications, ranging

26

from small problems

to

very large problems reqUInng

hundreds of

d-c

computing amplifiers and any

number

of nonlinear elements. This new computer automatically

checks

the

problem setup and

the

operation of each

computing element through a built-in program analyzer,

and records

the

result on a read-out printer. Goodyear

believes

the

concentration of parts and wiring in

the

patch bay area of analog computers generally results in

poor accessibility.

In

the

A-14,

the

resistor cards plug

into

the

back of

the

patchbay board, with connections

to

the

cards being made by taper pins. This eliminates

soldering,

and

makes possible easy replacement.

RECORDAK,

New York,

N.

Y., a subsidiary

of

EAST-

l\1AN KODAK, has opened a new product planning

department

to

investigate and develop new, improved

applications of microfilming including electronics auto-

mation. Studies will include a wide field of applications

where microfilming

is

used in electronic storage

and

retrieval of business

and

government information.

CLARY

CORP.,

San Gabriel, Calif., now produces a

self-contained scanning digital printer.

The

machine

converts a parallel set of decimal contact closures into a

printed digital record. Maximum printing capacity

is

12

digits per line, with a minimum printing rate of three

lines per second.

INTERNATIONAL

BUSINESS

MACHINES

CORP.,

New

York,

N.

Y., has announced two new

optional features -file search,

and

additional magnetic

core storage -to increase

the

capacity

and

flexibility

of

the

IBM

774

Tape

Data

Selector.

The

774 serves

as

a

basic translator between magnetic tape units

and

card-

operated machines by providing a punched-card "image"

of data recorded on

the

tape.

With

the

new file search

feature, users of

the

774 can rapidly locate any individual

record or class of records within a

file

of magnetic tapes,

at

a speed of 15,000 characters per second.

The

expanded

magnetic core storage permits up

to

33% more capacity

than

previously available.

The

same company has installed what

is

said

to

be

first tape-operated computer (an

IBM

Tape

650) in

the

investment

and

banking field,

at

Hornblower·&

Weeks

in

New

York.

Most

of

the

500

IBM

650 computers in-

stalled throughout

the

world have been punch-card

operated. Only a few

IBM

Tape

650's are in use.

One

reel of tape replaces 27,000 punch cards.

On

CBS-TV's program,

"Game

of

the

Week," a Saturday afternoon weekly televised baseball

game, three of these miniature indicators are used to

show

the

"up-to-the-minute" batting average of

the

player concerned. This figure along with

the

batter's

name

is

superimposed on

the

screen

as

each batter comes

to

the

plate. CBS-TV has also ordered additioI?-al units

to be used in

the

projection room to designate to

the

projection room staff, which camera

is

"shooting"

at

any

specific time.

POTTER

AERONAUTICAL

CORP.,

Union,

N.

J.,

has introduced a new digital

flow

indicator

and

totalizer

which can

be

adjusted to give a direct reading in gallons

or pounds per minute,

as

well

as

direct readings of speed

in revolutions per unit time. Used with two meters made

by

Potter,

the

new instrument will indicate

the

ratio

between two

flows.

The

indicator

is

suitable for many

types of flow rate measurement, and can

be

used

as

a

short-time totalizer, by means of four-digit readout in

%-inch-high figures on Burroughs Corp., Nixie tubes.

BENSON-LEHNER

CORP.,

West

Los Angeles Calif.,

has announced

OSCAR

Model N-2. This

is

a reading

machine with a 20" by 20" reading area to analyze data

recorded

as

images or traces on film or paper. Automatic

read-out of positions to various

output

units

is

instituted

by pressing a switch.

Anyone

of several standard pro-

jection systems may be incorporated where original

data

is

less

than

89

mm

in width.

Output

sequence con-

trol includes digits, sign position, typewriter control

signals such

as

tab or return,

fixed

digits, repetitive

subroutines, and generation of special codes for later

use

as

computer instructions.

The

accuracy of

the

de-

vice

is

stated to

be

I part in 5000. About

50

points per

minute maximum can be read, if

the

machine operator

is

skilled.

The

same company's new

ELECTRO

PLOTTER

Model S provides additional dimensions to

the

straight-

forward two-dimensional graphic displays of conven-

tional automatic plotting equipment.

The

new equip-

ment

can

be

used significantly in fields requiring multi-

dimensional plotting such

as

magnetic and gravimetric

mapping, topographical surveying, stress mapping in

structures, geophysical sub-section mapping, trajectory

flight tracing of ballistic and powered missiles, tabula-

tion of data for production control, automatic drafting

and lofting,

and

the

plotting of aerodynamics pressures

and stresses on solid sections.

The

equipment

is

par-

ticularly useful when plots are made

at

randomly-spaced

positions;

it

is

able to display simultaneously basic

values, elevation corrections, and second derivatives,

which can

then

be contoured by hand.

AMERICAN

ELECTRONICS,

INC., Los Angeles,

Calif., has introduced a new multi-channel magnetic

tape recording system

that

has a

300

kilocycle band

width, accommodates reels up to

14

inches in diameter,

and can record

16

GEORGE

A.

PHILBRICK

RESEARCHES,

INC.,

Boston, Mass., has introduced a new "Universal Sta-

bilized Amplifier" with printed circuit construction. It

is

an operational amplifier useful in assembling elec-

tronic analog computer circuits. (See picture above.)

BJ

ELECTRONICS,

division of Borg-Warner, Santa

Ana, Calif.,

is

marketing a series of standard 6" x

8"

plug-in etched circuit component cards.

The

cards,

de-

signed for use in

BT's

digital data system, are expected

to save time

and

effort in developing data processing

systems.

The

circuit card group comprises: flip-flops,

inverters, decimal counters, read-write amplifiers, cath-

ode followers, blocking oscillators, diode logic cards,

and

general purpose blank panels.

SPERRY

GYROSCOPE

has demonstrated a "true

tracking" radar, which presents in essence a continuous

picture of objects within range. This new system per-

mits an observer to tell

the

difference immediately be-

tween moving

and

fixed objects. For

the

first time in

American radar (Decca has had similar units installed

in European ships for

the

past year) only objects in

motion, instead of all objects on

the

scope, show in

motion.

The

new device also permits off-center posi-

tioning, to scan a larger area without changing

the

range scale.

FERRANTI,

LTD., London, England, in cooperation

with

the

British Oxygen Co., Ltd., has developed a

computer-controlled flame-cutting machine for cutting

steel plate.

The

new machine

is

said to include fully

automatic operation of

the

profiling process,

as

well

as

automatic controls for

the

blow pipes

that

cut,

the

ignition,

the

nozzle height sensing, and

the

cutter head

rotation.

ARTICLES:

\"Ve

desire

to

publish

articles

that

are

factual,

useful,

understandable,

and

interesting

to

many

kinds

of

people

engaged

in

one

part

or

another

of

the

field

of

computers

and

automation.

In

thh

audience

are

many

people

who

have

expert

knowledge

of

some

part

of

the

field,

but

who

are

laymen

in

other

parts

of

it.

Consequently,

a

writer

should

seek

to

explain

his

subject,

and

show

its

context

and

significance.

He

should

defi.ne

un·

familiar

terms,

or

use

them

in

a

way

that

makes

their

meaning

unmistakable.

He

!ihould

identify

unfamiliar

persons

with

a

few

words.

He

should

use

examples,

de·

tails"

~omparisons,

analogies,

etc.,

when·

ever

they

may

help

readers

to

understand

a difficult

point.

He

should

give

data

sup·

porting

his

argument

and

evidence

for

his

assertions.

We

look

particularly

for

articles

that

explore

ideas

in

the

field

of

computers

and

automation,

and

their

applications

and

implications.

An

article

may

certainly

be

controversial

if

the

subject

is

discussed

reasonably.

Ordinarily,

the

TECHNICAL

PAPERS:

Many

of

the

not

necessarily

apply

to

etc.,

may

be

COMPUTERS

and

AUTOMATION

for

August,

1957

11·S

To

one looking beyond the four walls

of

his offlce,

environment

might

be

deflned as the sum

of

(1)

work responsibilities

and

(2)

colleague personalities.

The

computer programmer

we

presently

seek

could not fail

to

be

stimulated by

(1)

work involving the construction

of

broad mathematical models

of

complex situations for simulation

purposes

on

a

704

digital computer, and by

(2)

colleagues

with considerable attainments not only in mathematics

but

in systems engineering, psychology, cybernetics, and sociology.

THE

ELEMENT

OF

ENVIRONMENT

To

qualify, at least one year's solid experience in high-speed

digital-computer programming is required,

plus conceptual and logical capacities

of

a high level.

A degree in mathematics or science is necessary.

The

Role

of

Computers Conclusion

[Continued

from

page

191

Computing Elements, Analog and Digital Computers,

the

SWAC.

Such a workshop experience will reach

the

students

in some

way,

some time. Already a junior high student

has helped edit

the

report manuscript, to turn up several

errors

not

caught by his teacher!

Computers will

~ave

a role to play in high school

science or mathematics education, and

the

success of

the

role will revolve about

the

teacher.

The

teacher can

acquire first-hand knowledge only by hard study and

first-hand participation. Industry can thus aid materially

by providing

the

proper opportunities for teachers (and

students too).

School-Industry Organization

In Los Angeles

Organization of

the

resources of

the

Los Angeles

co'mmunity

was

effected

by

a joint central committee

of

the

Superintendent of Schools, Los Angeles. Leaders

at

the

management level of

both

industry and education

agreed upon a plan of action.

The

widespread availability

of professional positions for teachers this summer

is

indicative of

the

success so far enjoyed. Planning for the

broader Southern California area will proceed

at

a

week-

long conference

at

Lake Arrowhead, July

7-13.

This

is

under

the

joint sponsorship of the National Academy

of

Sciences and Hughes Aircraft Company, with

co-

operation of the University of California, Los Angeles.

The

conference will review and evaluate pilot pro-

grams across

the

nation and dwell pointedly on

the

Southern California situation. It

is

hoped

that

both

of

these planning-action approaches will serve

as

incentive

and

example for community-school cooperation across

the

nation.

Solderless splice solves problem

STANDARDS

/

trouble-free

coil

windings

Solderless

splice

ends

failures

two

ways

The

two

chief causes

of

relay

coil

windings going open

in

service are:

(1) electrolysis,

and

(2)

breaking

at

the

terminal.

Automatic

Elec-

tric

prevents

these

difficulties

with

a winding

termination

technique

that

is

vitally

different.

We

do

not

attach

coil endings

of

fine wire directly

to

the

terminals.

Instead,

we carefully

strip

the

insu-

lating

enamel from several inches

of

the

coil ,endings

and

tightly

twist

this

length

of

wire

with

strands

of

bare

tinned

copper wire.

This

strong

solderless splice is

then

insulated

with

a special film sheet.

Because we

make

terminal

con-

nections

over

a long section

of

stranded

wire, electrolysis

has

no

single

point

to

attack.

And

this

flexible connection will never

snap

under

temperature

extremes

or

other

stress-producing factors.

In

every

step

of

relay

design

and

manufacture,

we

take

extra

pains

to

prevent

trouble

before

it

starts.
