ON HIS birthday, Rear Admiral Frank E. Beatty was given a crosscut saw by officers, bluejackets and civilian scientists of the Naval Ordnance Laboratory in Washington, D. C. "What's this for?" he asked. "A professional joke," said a spokesman. "We figured that you'd need something to help cut up those knotty problems we're going to run into at White Oak." White Oak—938 acres of rolling Maryland countryside 12 miles north of Washington, D. C.—is one of the Navy Bureau of Ordnance's newest research centers.

At the Traffic institute, veteran officers â€”finest in the countryâ€”are pumped full of facts on how accidents happen and how to help motorists behave By Clifford B. Hicks SEVENTEEN HUNDRED police officers from every section of the country have been learning the finer points of traffic enforcement at Northwestern University's Traffic Institute since 1936. It's not entirely coincidence that the national death rate per 100,000,000 vehicle miles has been cut more than halfâ€”since 1936. Even faculty members don't suggest that the institute is solely responsible for this startling reduction in fatalities. Yet during the past 12 years those 1700 officers, crammed with knowledge of how accidents happen and what to do to prevent them, have taken over key positions on traffic police forces throughout the country. And the institute's sister organization, the Traffic Division of the International Association of Chiefs of Police, has probed traffic enforcement in 60 cities, counties and states and made recommendations that invariably have brought surprising slashes in the accident rate.
RADIO receivers, tinier than a penny matchbox have been developed by Paramount sound men in Hollywood. These replace the megaphones that directors used in the days of silent pictures to shout instructions to their stars. The resulting confusion on crowded sets was nerve racking to both the director and members of the cast. When sound was added, the megaphone had to go. It was then replaced by intricate signaling systems and many necessary interruptions and expensive retakes. Now this tiny inductive-type receiver, that uses no batteries or tubes, is concealed on the actor's person. It is claimed that it can pick up signals as far as 300 feet away from the transmitter which is placed near the movie studio stage.
Trial by “Sound Jury” After Bell Laboratories engineers have designed a new talking circuit, they measure its characteristics by oscilloscopes and meters. But a talker and a listener are part of every telephone call, and to satisfy them is the primary Bell System aim. So, before the circuit is put into operation, a “sound jury” […]

By Andrew Hamilton THE OLD INDIAN rope trick has amazed and mystified people for generations. A fakir throws a rope above the stage where it stands without apparent support, as stiff as a rod. The trick is simply this: an unnoticed four-pronged hook at the end catches a taut piano wire in the dim light above the stage. This vaudeville stunt is not half as amazing as the miracle of rope itselfâ€”one of mankind's most useful tools.
Pocket-Size Exposure Suit Exposure, one of the biggest trials of airmen downed at sea, is curbed by an inflatable rubber suit small enough to be rolled into a pocket in the collar of a Mae West jacket. It weighs less than three ounces and provides air insulation against cold and damp. The suit is being […]
Metal Rotors Help Helicopter Fight Ice All-metal rotor blades and a cabin floor hatch are novel features of a Sikorsky helicopter being tested by the Navy for use on carriers, battleships and cruisers. The blades are more easily adapted to de-icing equipment than the wooden ones now used and are less likely to be damaged. […]
