...keep the radio spectrum clear of outmoded but garrulous space vehicles, the National Aeronautics and Space Administration is turning to the small electronic timekeepers that Bulova Watch Co. developed for its Accutron wrist watches. To measure time, these timers use a transistor-controlled tuning fork that runs indefinitely on a tiny trickle ( eight-millionths of a watt) of electric power; a battery the size of a dime will keep one of them humming for a year. The whole apparatus weighs less than three ounces, and it can easily be set to turn off a satellite's transmitter after...
...PIANO. An electronic portable piano built into a case about the size of a two-suiter has been put on the market by the Wurlitzer Co., De Kalb, Ill. Like the Micro-TV, it operates on house current or a battery pack. With a 64-note keyboard, the all-transistor piano can be played via built-in loudspeaker or earphones (for silent practicing), has controls to vary the tone from Hawaiian guitar to vibraphone to glockenspiel. With case, bench, battery pack and earphones, approximate price...
...missionaries in eastern Assam began to pull out, turning over mission schools and hospitals to Indian assistants. Some imported food was in short supply, and India's banyas (village shopkeepers) took advantage of the situation to boost prices. The evidence of the Chinese advance came, oddly enough, from transistor radios. At first it was possible to tune in on Indian army short-wave transmitters and hear orders and messages in Urdu. From midweek on, Indians listened to the messages of the advancing Chinese. An added source of information was the sibilant voice of a young Indian woman, who reads...
There are two types of transistorized systems. The simplest send only a small current through the breaker points, thus saving wear. The small pulsating current from the points triggers a transistor system that in turn controls the high current needed by the coil. Manufacturers claim that such systems save fuel, give more fire power, make both points and plugs work indefinitely at top efficiency at any speed. An even more rewarding system produced by New Jersey's Motion Inc. includes a capacitor that is charged by the high-tension current that is normally fed directly from coil to spark...
Dropping his regular research to investigate, Dr. Rindner led a Raytheon task force in painstakingly devising a tiny bit of metal shaped like a thumb tack and mounting it so that its stem pressed on a transistor's sensitive spot. This device, smaller than a pinhead, performed as an excellent microphone. It can be made to transmit music faithfully, and can even pick up ultrasonic sounds to which the human ear does not respond...
