Utilizing Ferramic Magnetic Memories resulted in important increases in
reliability, speed and accuracy in actual operation. In addition, designers found
space requirem~nts sharply reduced. Lower power consumption, lighter weight,
elimination of heat dissipating devices and greatly reduced maintenance were
other significant improvements.
General Ceramics Magnetic Memories offer a solution to similar problems
in automatic control systems for conveyors, elevators, telephony, production
machines, processing equipment and signalling. For further details, write General

EDITOR'S

PRINTING BY LETTERPRESS
AND OTHER CHANGES
Beginning with July, regular issues of "Computers and Automation" will be printed by letterpre ss and will no longer be printed by photooffset.
We now have over 2600 subscribers allover the
world, and have reached the place where letterpress printing of regular monthly issues makes
sense. We think there will be a considerable improvement in appearance and legibility, which we
hope our readers and our advertisers will both
like. We expect that there will be an increase of
the amount of information published in each issu~,
although because of the condensation possible with
printing type there may be fewer pages. (Note:
Unusually large issues may still be photooffset.)
We shall as always keep trying to improve
"Computers and Automation" so that we may continue to serve loyally the be st intere sts of computer people. All suggestions from our readers are
always welcome.
In fact, another change we are considering

is changing the name of the magazine. Perhaps
the name "Computers and Data Processing" or
"Computers and Data Automation" would be more
suitable. If you have comments, please let us hear
from you.

THE COMPUTER DffiECTORY
AND BUYERS' GUIDE, 1957
The third edition of "The Computer Directory", the June issue of "Computers and Automation", is here presented; 104 pages long~ with the
hope that it will prove essential to the work of
people in the computer field.

NOTES

This Roster is, as we have mentioned before,
the reason for our existence as a magazine, since
our first issue, Vol. 1 No. 1 in September 1951,
consisted only of a purple ditto, list of organizations
in the computer field.
"Part 2, Buyers' Guide for the Computer
Field: Products and Services for Sale or Rent",
contains about 1370 entries on 39 pages. This is
larger than last year's, which contained slightly over
700 entries on 35 pages.
The main reason for the rather large increases
in these figures is that this year we have made rather a careful search through many publications for
new organizations, new products, and new services
that might be listed in our rosters. The inclusions
have been more on the wide and unselective side
than on the narrow and selective side - because a
user of information will always find it easier to exclude a suggested name from a list than to rack his
brains to include additions missing from a list.
"Part 3, A Pictorial Introduction to Computer s", included in the directory this year, is an
effort to show a little more visually than by words
alone what some of the kinds of products in the
computer field look like.
A revised and up-to-date "Roster of Automatic Computers", which was included in the directory last year, is not included this year, but will
be published in an early issue of "Computers and
Automation" •
As usual, we ask our readers to be kind enough
to tell us of additions, corrections, and revisions, so
that we can continue to make the reference information that we publish useful and reliable.

"Part 1, Roster of Organizations in the Computer Field", contains about 795 entries on 30 pages.
This is larger than last year's; which contained
about 370 entries on 18 pages.

Many of these entries have been based on information provided by the organization itself, and
have been improved from time to tim e as change s
have been reported. Many other entries are new;
and some perhaps are borderline entries, as for
example organizations making magnetic recording tape, who may be much more in the acoustic
field than in the computer field.

The purpose of this list) '~he Buyers'

it covers abou t 39 pages and contains over l:J>O

Ouestionnaire. Many of the entries in
this list have been derived from answers to
questionnaires which we sent outin February,
March, and April to over 300 suppliers in the
computer field. The form of this questionnaire, called the "Product Entry Form", is
shown on page 43.
For a new or changed entry. the information we want is asked for on this form; the
answers may be written on the form or on any
piece of paper. Customary sales literature
is difficult for us to use, and need not be
sent.

There are two classes of entries in this

Class One entries are those for which·THE
NAME OF THE SUPPLIER IS ALL IN CAPITALS., Class
One entries are likely to be complete and ... reliable; the supplier. has either sent us his
entry in response tOI~ur questionnaire or approved the proposed entry which we sent to him;
he has thought enough ·.of'.~~he value. of' the entry to pay the requested nominal charge of $10
per entry, to help defray the cost of preparing and printing this part of the directory;
and we have edited the entry, though usually
in a minor way. An index to Class One entries
by name of supplier has been provided.

fIELI):

Style of Entry. The full entry for a
product or service in the list consists of:
name of supplier, address / name or identification of product or service / DESCR: a brief
description of the product, in about 20 to 50
words -- see examples in the list / USE: how
it is used / price range, and whether for sale
or rent. Every entry is subject to editing.

Class Two entries are those for which the
name of the supplier is not all in capitals.
Such entries are derived from other information reaching us. In some cases answers to
questionnaires have been received where the
supplier has not believed it desirable to make
any payment; many of these entries have been
condensed. In many cases, we have had no information at all from the supplier enabling
us to verify what we have said about his product or service. In general, Class Two entries
are less likely to be complete and reliable.
- 40 -

Abbreviations. The abbreviations used
include: DESCR -... description; *a -... address
above (where several products made by one supplier are listed in succession).
Corrections. We have tried to make each
entry correct to the extent of information in
our possession. But it is inevitable that at
least some errors have occurred, and we shall
be glad to publish corrections. There will
be no charge of course where the incorrectness
of information is attributable to our error;
in other cases there will be a requested nominal charge of $10 an entry to be paid at the
time when the new entry is sent in to us.

PICTORIAL

INTRODUCTION

TO

COMPUTERS

Most of the time computers are not photogenic - not "suitable for being photographed for artistic
purposes", as the dictionary defines "photogenic". Why not?
Because taking a picture of a computer to show how it is processing information is like taking a
picture of a man's forehead to show how he is t1)inking: it shows almost nothing. In other words, if you
would like to "see how a computer works", you need to look at circuit diagrams and trace pulses of information through them. And since a computer's speed is fantastic, you also need to use instruments (an oscilloscope for example) which will picture the pulses slowed down to human speeds.
But we have now collected some computer pictures which can answer some questions, such as:
What does a computer look like? What does a magnetic drum look like? and more besides.
Some of
these pictures we have included here in "A Pictorial Introduction to Computers". We plan to publish
more in subsequent issues of "Computers and Automation". If any of our readers have good pictures
answering questions of the type "What does a ....•. look like? It, we shall be very glad to consider them
for publication.

WHAT DOES A COMPUTING CENTER LOOK UKE?

Here is a picture of a computing center at the Ramo-Wooldridge Corporation in Los Angeles. Its
main purpose is the reduction of data received by telemetering from experiments with flying aircraft, rockets, missiles, etc.

This view shows a part of a circular array of electronic equipment, which has been assembled into a system for converting telemetered data rapidly into forms suitable for further analysis and study in detail.

- 49-

WHAT DOES A COMPUTER LOOK LIKE?

Here is a picture of a computer - an electronic analog computer known as "Computer Group
16-13IR", made by Electronic Associates, Long Branch, N. J. This is a general purpose computer for
mathematical and engineering problems to be solved by analog methods and using electronic signals. The
capacity of the machine may be increased by cables connecting it to more equipment. Also, the machine
may receive input translated automatically from digital into analog form, so that nume~ical coefficients
may be given easily to the machine and mathematical functions may be easily generated .

WHAT DOES AN INPUT DEVICE LOOK LIKE?

Here is a picture of an example of an input device - a fast photoelectric reader of punched paper
tape, made by Potter Instrument Co., Great Neck, N. Y. It is modeled on the fast magnetic tape reader
made by the same company. Note the small arm-like mechanisms for taking up slack in the tape, which
provide for very much faster starting and stopping than if the tape reels alone had to be accelerated or
decelerated.

WHAT DOES A LITTLE MAGNETIC DRUM LOOK LIKE?
A magnetic drum stores information, in the
form of yeses and noes (binary digits) represented
by magnetically polarizeq spots. Here is a picture
of a miniature magnetic drum, which can store over
12, 000 binary digits of information. It was developed
by BJ Electronics, Borg-Warner Corp., 3300 Newport
Blvd., Santa Ana, Calif.
The aluminum drum with magnetic surface
measures 3-1/2 inches diameter and contains 12
information channels plus clock and checking channels. Each channel is seven hundredths of an inch
in width, and can store 1024 bits.
The drum is driven by a belt at speeds varying up to 15, 000 rpm. Access time is apprOximately
1. 25 milliseconds. The outside case is 6 inches diameter.

WHAT DOES A BIG MAGNETIC DRUM LOOK LIKE?
Here is a picture of a magnetic drum which will store millions of binary digits of information.
This drum is part of a system of reporting inventory quantity (on hand and on order) of boots and shoes for 3000 styles and colors, with an average of 10 sizes per style, and up to 4 decimal digits of inventory
information for each combination of style and size. The drum is 20 inches in diameter, 30 inches long, and
spins at 1300 revolutions per minute. It is partially hidden beneath wires which lead to the magnetic heads
that "read" and ''write'' information on the drum. It is the heart of an inventory control system manufactured by the Teleregister Co. for the B. F. Goodrich and Hood Rubber Company in Watertown, Mass.

- 52 -

WHAT DOES PROGRAMMING LOOK LIKE?

Most of the time it is not possible to see programming, since it consists of a long series of instructions stored inside the machine, quite often in the form of invisible polarized spots on a magnetic surface.
But in the case of the E10l "desk size" automatic computer (made py ElectroData Division of Burroughs
Corporation, Pasadena, Calif.), the programming is given to the machine in the form of arrays of pins in
a plugboard. The pattern of pins in the plugboard is a good picture of the selection among many possibilities
which a program conveys to a computer.

- 53 -

WHAT DOES A VISUAL OUTPUT LOOK LIKE?
A "visual output" is a device which displays answers or results visually before human eyes.
One kind which is new, important, interesting, and inexpensive is a glow tube called Nixie,
made by Burroughs Electronic Tube Division, Plainfield, N. J. It converts anyone of ten electric signals
directly into anyone of ten digits 0 to 9. As the first picture shows, a wire frame inside the tube outlines
the possible digits; then when an electric potential is put on anyone of the wires a' glow (like a neon tube
glow) results, brightly illuminating the space around the wire. In the second picture, a 5 is glowing. The
top of the tube is about the size of a quarter.

View from the Side, not glowing

View from the top, glowing

Another kind of visual output is called an X-Y plotter. Above is a machine which automatically
plots a curve on graph paper with two rectangular coordinate axes, the X-axis and the Y-axis. Pictured
above is an example of such a machine, a Type "A" X-Y Plotter, made by Librascope, Glendale, Calif. It
can graph a curve swiftly and automatically, taking in information in decimal or binary notation through a
converter from punched cards or punched tape.

-54-

WHAT DOES A SEMICONDUCTOR LOOK LIKE?

Here is a picture of a great number of semiconductors, mounted together one after another in a
long strip, like bullets in a belt for a machine gun. The special "machine gun" shown here "staples" the
semiconductors into printed circuit assemblies, thus eliminating the hand assembly formerly required,
and greatly speeding the process. The semiconductors are made by Hughes.-Aircraft, Culver City, Calif.,
and the machine for inserting them was adapted by engineers of Hughes Aircraft.

- 55 -

WHAT DOES A MAGNETIC TAPE REEL LOOK LIKE?

Here is a picture of a reel for
holding magnetic tape, with a curved
groove or "C" slot in the hub for
easy threading of tape and self locking. It is made by Audio Devices,
Inc., New York, N. Y.

WHAT DOES A MAGNETIC TAPE FILE LOOK LIKE?

Here is a picture of a small
mobile cabinet made by Remington
Rand, New York, which will store
many reels of magnetic tape and
move them from place to place
easily.

The mall:-made "moon" which is to be launched
during the International Geophysical Year will whirl
through space at 18,000 miles per hour, actually
circling the earth once every 96 minutes.
To help scientists track the speeding sphere, a
small radio receiver-transmitter-activated by impulses from earth~will periodically send out radio
signals to ground receiving stations. These signals
will be recorded on magnetic tape for immediate and
subsequent analysis.
The tape chosen for this unusual and significant
recording assignment was Type EP Audiotape.
The "extra-precision" which qualifies EP Audiotape, for important jobs like this one is achi~ved
through a rigid program of quality control. Every
facet of the manufacturing process, from the selection of raw materials to the final packaging operations, is scientifically supervised. Tpe result is an
instrumentation tape which will meet the most exacting standards of uniformity and freedom from
microscopic imp'erfections.
In telemetry, electronic computers, or any other
magnetic data recording work, Type EP Audiotape
consistently delivers top performance.

ELECTRONIC COMPUTER CHARTS
GAME - TEACHES BUSINESS
EXECUTIVES HOW TO MAKE
DECISIONS

-FERRANTI
HIGH SPEED 'APE READER

A new "game" simulating the world
of business has been introduced by the American Management Association. .. which
uses an electronic computer to keep score.
Five teams of business executives, given
an equal start in a multi-million dollar
"Monoply-like" market for Widgets, compete to amass the most assets. The decisions of each team on what to do with
available cash, plant capacity, priCing,
are fed each 20 minutes into the computer
. .. which then calculates what share of the
market each team has captured. The game,
utilizing an IBM computer, is to be the core
of a course in "how to make decisions". By
next year some 4000 game-playing top-executives will have been exposed in this way
to one small facet of the fantastic capacity
of computers.

SUMMER COMPUTER COURSES
Ann Arbor. A group of six courses
"in Digital Computers will be given at the University of Michigan College of Engineering
from August 19 to August 30 of this year.
The emphasis in these courses is on modern
computational techniques. They are designed primarily for persons already experienced in some aspects of computer technology. For information, write to Engineering Summer Conference, 2038 East Engineering Building, Ann Arbor, Wlichigan.

Detroit. - The Fifth Summer Computer Program of Wayne State University ( Detroit) is being given at the Computation Laboratory in two parts this year. The first
half, "Introduction to Computers and Their
Application, and Data Processing in Business and Industry" was offered early in June.
The second half of the program, "Industrial,
Management, and Scientific Applications of
Computers" will be offered September 9 to
14. This course is planned to follow directly a three-day Conference on Matrix Computations also at the Computation Laboratory.
For information, WI'ite to A. W. Jacobson,
Special Summer Program, Wayne State
University Computation Laboratory, Detroit

The Ferranti High Speed Tape Reader accelerates
to full speed within 5 milliseconds and stops within,
3 milliseconds. It has been in use at leading computer
installations for over two years and has achieved a sound
reputation for simplicity and reliability in regular operation.

-IJi' (

1) Mark II model reads at speeds up to 200 characters per
second, and stops the tape from full speed within a character positionwithin .03 inch. The tape is accelerated to full speed again in 5 milliseconds
and the following character is ready for reading within 6 milliseconds of
rest position.
(2) Mark IIA model reads at speeds up to 400 characters per second,
and stops within .1 inch.
VERSATILE Both models read either 5 level, 6 level or 7 level tape
by simple adjustment of an external lever.

WiMf4'W The tape is easily inserted without complicated threading.
Lap or butt splices are taken without any difficulty. The same tape may be
passed thousands of times without appreciable tape wear. The optical
system has no lenses or mirrors to get out of alignment. Friction drive is
independent of sprocket hole spacing.
LARGE OUTPUT Amplifiers are included for each channel, including
a special squaring circuit for the sprocket hole signal. Output swing
between hole and blank is greater than 20 volts.
Dimensions: 9'( x 11 %" x 11 1/.&"
Weight: 371bs.
For use with long lengths of tape up to 1000 feet, spooling

equipment operating up to 40 inches per second for take-up
or supply is available separately.

ROBOT MACmNIST
The Air Force has just accepted delivery on the
first electronically controlled device to turn out titanium blades for jet engines. This special-purpose machine tool, made by the Douglas Tool Company of Detroit, cuts out the intricate twisted airfoil section of
a blade, ready for final polishing, at the rate of one
every 11 minutes - some 4 to 5 times as fast as the
machines it is designed to replace.

SELF.REJUVENATING
CLARE RELAY

*****
50 TON MILLING MACIllNE
CONTROLLED BY CODING TAPE
To increase speed of production of preci'sion
parts by a 50 ton milling machine, the Glenn L. Martin
Company has purchased a Bendix built autpmatic tapefed control system~ . The. controller senses the program punched into the tape, and actuates the massive
machine tool which £urns out parts automatically for
Matador missiles and SeaMaster airplanes.

Ponce de Leon failed in his quest for a "fountain of youth," but modern design engineers
find rejuvenation an accomplished fact in
CLARE Mercury-wetted Contact Relays ...
capable of billions of operations.
Contacts of these relays are constantly renewed. By capillary action~ like that of a
lamp wick, a new film of mercury coats the
contacts with every make and break.
The magnetic switch is sealed in a highpressure hydrogen atmosphere in a glass capsule. Surrounded by the operating coil, the
capsule is enclosed in a vacuum-tube-type steel
envelope.
Unlike ordinary relay contacts, these contacts never wear out; never get dirty;
never lock or weld; never get out of
adjustment; never bounce.

*****
ANALOG TO DIGITAL CONVERTER
FLASHES ACTUAL TmCKNESS OF STEEL STRIP
Faster, more accurate reading of finished strip
steel thickness is reported by the 80-inch strip mill
of U. S. Steel Fairless Works, Fairless Hills, Bucks
Co., Pa. The method uses a device which converts
passage of X-rays through the mOving strip into an
actual thickness readout. The varying intensities of
the X-rays are recorded by a scintillation detector;
the meter readings are then converted into electrical
voltages by a computer device; the electrical voltages
are then summed, and applied to an analog-to-digital
converter, which displays the actual thickness in
thousandths of an inch in a row of 3 illuminated figures. ~tRead-outs" at several points are also printed
through a printing cycle controller.

Drawings (left) from stroboscopic photographs show the cycle. (a) Filament of mercury forms between the contacts as they
separate. (b) This becomes narrower in
cross section and (c) finally parts at two
points, allowing a globule of mercury to fall
out. Mercury flows up the capillary path
to replace the amount lost and restore the
equilibrium. (d) The momentary bridging
of the parting contacts-and the extremely
fast break that ends it-minimizes the arc
and adds greatly to contact load capacity.
Contact closure between the two liquid surfaces bridges mechanical bounce and prevents any chatter from appearing in the
electrical circuit.

We are interested in articles, papers. ref.erence
information. and discussion relating to computers
and automation. To be considered for any particular issue, the manuscript should be in our hands
by the fifth of the preceding month. Ordinarily,
the length should be 1000 to 4000 words.

Articles. We desire to publish articles that are
factual, useful, under~tandable. and interesting
to many kinds of people engaged in one part or another of the field of computers and automation.
In this audience are many people who have expert
knowledge of some part of the field, but who are
laymen in other parts of it. ·C~nsequently a writer should seek to explain his subject, and show
its context and significance. He should define
unfamiliar terms, or use them in a way that makes
their meaning unmistakable. He should identify'
unfamiliar persons with a few words. He should
use examples. details, comparisons, analogies.
etc., whenever they may help readers to understand a difficult point. He should give data
supporting 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. A suggestion
for an article should be submitted to us before
too much work is done.

a quick check of indent-depth tells you
this elect1~ical connectiol1/ is safe!
There's no way to check a soldered connection-without destroying
that connection! The modern Burndy crimping method affords
a quick check for electrical and mechanical safety-simply by
measurement of this depth of indent. The cross-section view (right) shows
how this indent is designed to coin conductor and connector
into intimate contact. .. for a strong connection, as electrically sound
as the conductor itself. And the depth of indent is controlled
by the installation tool! Unlike solder which can weaken at high
temperatures frequently encountered by modern equipment, the Burndy
crimped connection with its wide tolerance endures in all environments.
Too-Burndy electrical connections get rid of human error-no skill or
training is required. The control is engineered into the connector and
the tool! Put a crimp on rising production costs !-send for the full story
on Burndy crimp-type connections, today!

ANOTHER FIRST FOR EAI
AN ELECTRONIC DIGITAL VOLTMETER
The new electronic Digita l Voltmeter, Model 26-26B from Electronic Associates, Inc ., enables readouts at speeds formerly thought impossible.
A unique transistoriz ed digital comparator converts analog inputs to the
binary coded d ecimal sys tem in an average time of 0.05 seconds. Delays in
r eadout time are reduced by a factor of 100. Readout accuracy is maintained
at 0.01 Volts.
'These adv a nces are made possible because of this Digital Voltmeter's compl et ely electronic and transistorized design. The progressive measuring and
digitizing circuitry r equir es no moving parts at all. This results in extreme speeds, noisel ess operation, and the greatest reliability.
The Digital Voltmeter is a nother first in EAI's Program of PACE. For complete details on this , and on any of the Computation Centers maintained by
Electronic Associates, Inc. in Princeton, N. J ., Los Angeles, California, or
