These signals find the way (Jan, 1953)

These signals find the way

When you dial a telephone Dumber, high-speed switching mechanisms select your party and connect you. Through a new development of Bell Telephone Laboratories, similar mechanisms are doing the same kind of job in private wire teletypewriter systems which America’s great businesses lease from the telephone company.
Company X, for example, operates an air transportation business with scores of offices all over the country. At one of these offices, a teletypewriter operator wishes to send a message, let us say, to Kansas City. Ahead of the message, she types the code letters “KC”. The letters become electric signals which guide the message to its destination.
Any or all stations in a network, or any combination of stations, can be selected. Switching centers may handle 50 or more messages a minute . . . some users send 30,000 messages a day. Delivery time is a few minutes.
Defense manufacturers, automobile makers, airlines and many other American businesses are benefiting by the speed and accuracy of the new equipment — another example of how techniques developed by the Laboratories for telephone use contribute to other Bell System services as well.

Just hearing a pin drop is easy… (Apr, 1954)

I think these guys should sue Sprint for stealing their catch-phrase.

Just hearing a pin drop is easy…

Bruel & Kjaer instruments analyze sound and put it in writing for you
Since Bruel & Kjaer instruments present essential data so easily, they greatly simplify the analysis and control of sound, vibration, and noise.

For example, the Spectrum Recorder automatically “scans” any sounds from 35 to 18,000 cycles per second in third-octave steps. Chart records, produced immediately, indicate both frequency spectrum and signal amplitude. The instrument saves hours of engineering time in analysis of sounds and vibrations, and in studies of strains, pressure variations, complex electrical voltages, and magnetic tape recordings.

Developed for laboratory use, the line of Bruel & Kjaer instruments is finding ever-broader use in industry. For information on acoustical and electro-acoustical measurements that can be made easily with these instruments, write Brush Electronics Company, Dept. B-4, 3405 Perkins Avenue, Cleveland 14, Ohio.

2 Computers? No-Just One (Sep, 1952)

2 Computers? No-Just One

IDA!

Integro-Differential Analyzer
Leading design and research engineers have found that one IDA computer does the work of 2 ordinary computers — because of such ahead-of-the-field features as those outlined below:

Interchangeable Set-up Boards: permit problem change-over in minutes; thus IDA is always at work, there’s no lost set-up time!
20 Uncommitted Amplifiers: perform any computing function; and any required scale factor may be used for any number of inputs to any amplifier.
Hold Control: usually found only in most expensive computers, permits introduction of gross non-linearities.
8 Initial Conditions: once fixed, are automatically restored after each solution.
New Extra-Convenient Compactness: with the IDA you can actually sit at your desk while you compute!

Read for yourself the complete story on the truly advanced IDA computer. See how its twofold greater efficiency boosts your owa Just write for Catalog SA. Includes theory, set-up, typical examples.

Promise of a golden future (Mar, 1953)

Promise of a golden future
Yellow uranium ore from the Colorado Plateau is helping to bring atomic wonders to you

Long ago, Indian braves made their war paint from the colorful sandstones of the Colorado Plateau.

THEY USED URANIUM-Their brilliant yellows came from carnotite, the important uranium-bearing mineral. Early in this century, this ore supplied radium for the famous scientists, Marie and Pierre Curie, and later vanadium for special alloys and steels.
Today, this Plateau—stretching over parts of Colorado, Utah, New Mexico, and Arizona —is our chief domestic source of uranium. Here, new communities thrive; jeeps and airplanes replace the burro; Geiger counters supplant the divining rod and miner’s hunch.

What’s it like to be a Boeing engineer? (Sep, 1952)

My favorite part is the caption: “Solving a dynamics problem with the Boeing Computer”. THE Boeing computer? What just the one? Do they all have to share?


What’s it like to be a Boeing engineer?

Boeing engineers enjoy many advantages — among them the finest re-search facilities in the industry. These include such advanced aids as the Boeing-designed, Boeing-built Electronic Analog Computer shown above.
This is part of the stimulating background that helps Boeing men maintain the leadership and prestige of an
Engineering Division that’s been growing steadily for 35 years.

MARVEL Mystery Oil (Feb, 1952)

I’m not really sure what they’re trying to say in this ad… I think it’s either: “Marvel Oil will blow up your car”, or “Marvel oil is made of atomic bombs”.

FOR POWER
AND PERFORMANCE!
MARVEL Mystery Oil

More than 30 years of scientific research have gone into Marvel Mystery Oil, to meet the lubrication demands of today’s high – compression engines. Use in crankcase, gas tank, or top cylinder oiler… the ideal cure for hydraulic valve trouble.

“REPORT FROM ROTTERDAM” (Apr, 1944)

I think this is the only time i have ever seen the word rape used in an advertisement.


“REPORT FROM ROTTERDAM”

Secret underground broadcasters still send out news of what the brave Dutch are doing to upset the Nazi “new Disorder”. Radio furnishes the ONE link between conquered countries and the outside world. In war, as in peace, The Radio Shack continues to play its part in the field of communications . . . now supplying vital equipment to help hasten the day of victory, and revenge for the rape of Rotterdam.

Digital Graph Plotter (Sep, 1952)

THE NEW LOGRING
Digital Graph Plotter

THE LOGRING DIGITAL GRAPH PLOTTER automatic-
ally plots one variable against another algebraically in incremental steps, in response to electrical impulses. It is ideally adapted for use as a read-out device for electronic digital computers, especially digital differential analyzers, and for use in connection with such problems as aircraft tracking and automatic data reduction.
• plots at speeds up to 20 steps per second, in incremental steps of 1/64 of an inch.
• simultaneous movement on both axes in either direction.
• can be controlled electronically or by external or remote switches or relays.
• will make several carbon copies or duplicating stencil.
• instant manual positioning of pen and drum.
• takes 12″ x 18″ paper or continuous 12″ strip.
Mechanical simplicity ..high reliability ..digital accuracy ..quick pen cartridge change..self-contained power supply.
