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

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
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.

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.

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.

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.
