Scientific Tricks of Master Spies
By Donald Gray
Amazing beyond belief are the scientific tricks employed by modern spies to help them carry out their dangerous work without detection. All the resources of chemistry and mechanics, ranging from secret inks to marvelous enciphering machines, are made to serve the master spy, as set forth in this startling article.
Maybe No Noise in Future Wars
EXCEPT for the bursting of high explosive shells, wars of the future may be comparatively silent affairs, thanks to a new silencer just perfected by Ronald Chapman, of Caterham, England.
The silencer, which comprises a small cylinder about two inches in diameter and six inches long, fits onto the end of the gun barrel as demonstrated in the accompanying photo. The sound muffling mechanism which the inventor has not made known, absorbs more than four-fifths of the noise, and all flash and smoke.
With these qualities, the device becomes ideal for snipers and machine gunners in war time, and maybe use for it can be found in the gangster empire, where an “on the spot” job could be achieved with a minimum of disturbance to peaceful non-combatants.

MYSTERY RAYS “SEE” Enemy Aircraft
AMERICAN and German War Departments announce simultaneously new rays capable of “seeing” enemy aircraft through fog, clouds, or dark, at distances of up to fifty miles. First tests in this country are being held at the Lighthouse Station near Highlands, N. J., by the War Department, the details of the invention being closely guarded by military police.
No larger than a penny match box is the German mystery ray machine, a highly-perfected ultra-short wave radio transmitter.
Groups of these transmitters, mounted along the border of a country and adjusted to send their “feeler” beams into the sky at a fixed angle, could be used for air defense. The 5 to 15 centimeter long beams act much like invisible light rays, and are reflected back to earth by aircraft.
Groups of ultra-short wave receivers stationed some distance from the transmitters would pick up one or more of the beams reflected. With each transmitter sending out a different type of signal, something like the interrupted signal produced by a dial telephone, and each receiver connected to the central switchboard, the distance and height of the plane could be calculated automatically and almost instantly by a machine built to interpret optical and trigonometrical formulas. With this data, air defense guns could be aimed accurately at the unseen targets.
Dependable performance is a quarter-century tradition at Motorolaâ€” the world’s largest exclusive manufacturer of electronic equipment. Under subcontract to Convair, Motorola engineered for reliability, and is now producing the guidance equipment for the Navy’s new all-weather anti-aircraft missile, the “Terrier”.

Details on the NX2 – Our Atomic Plane
When will our “hottest” bomber take to the skies? How will it perform? What about the radiation danger? Here are the answers
By JAMES JOSEPH
OUR long-awaited atomic-powered airplane – Convair’s Model NX2 – is finally on the drawing boards, its components in various stages of construction and testing.
After 14 years’ research and an investment of close to 1 billion dollars, the plane’s reactor is under test and two different engine systems, both slated for early flight testing, are in advanced development.
I, for one, sleep soundly at night knowing that should we be attacked with chemical weapons, our brave typists will still be able to do their duty to their country.
Gas Mask Designed for Typists
ANEW type of gas mask, which slips over the head of an office typist in the event of an air attack, has just been developed in Rome, Italy. The face of the mask is transparent so that the typist can see what she is doing.
It looks like you should be able to wind up that key in his back and make him march.
Portable Army Radio Tested
A PORTABLE field radio transmitting and receiving set that operates while strapped to a soldier’s back was satisfactorily tested by the Royal Corps of Signals at Alder-shot, England. The device features a special loop-type antenna, standard earphones and a hand microphone. The power supply unit is self-contained.
This guy doesn’t look camouflaged, he looks trapped.
Snipers in Camouflage Nets Difficult for Invaders to Spot
England’s army includes a trained corps of snipers to help impede the progress of attackers. Besides being an expert marksman, a sniper must know many tricks of camouflage, one of which involves covering himself completely with a large-mesh net that effectively conceals him under certain conditions.
