...mouth when people chew, drink or swallow, Dr. Samuel Adams II, 28, and his associates at Rochester, N.Y.'s Eastman Dental Dispensary, have been bugging the bridgework of volunteers with tiny radio transmitters fitted into dummy teeth. Crammed inside each electronic tooth are a transistor, an induction coil, two capacitors, a resistor and a hearing-aid battery- all miniaturized items developed by the Air Force. Once the radio denture is in place, the subject enters a Faraday cage, a metal-mesh enclosure that blocks out most outside electrical disturbances. As the subject chews and drinks in his static-free...
...Tool and Manufacturing Engineers, engineers from General Dynamics' General Atomics Division demonstrated how the principle works in practice. Magneform - a tool little larger than a home washing machine and using no more current than an electric range - has no moving parts at all. Its essential part is a coil of heavy wire that can take var ious shapes, including a cylinder, a doughnut or a flat disk. When a massive electric current from a capacitor is shot suddenly through a coil, it creates an intense magnetic field in the space around it. If a piece of metal is near...
...different coils do different jobs. When the end of a metal tube is inserted into the doughnut-shaped coil, it can be shrunk tightly around any insert such as a plug or a threaded fitting. To expand a metal tube, a cylindrical coil is pushed inside it. A flick of the switch, and the tube expands to bind itself solidly to whatever surrounds it. To stamp a flat piece of metal with a pattern, a trademark of elaborate lettering, the metal is placed between a flat coil and a die. When the coil is activated, the opposing magnetic field...
...hush-hush, rush-rush affair, for which they secretly flew up from Toronto-where Dick is doing Hamlet-in a chartered Viscount. By 2:20 that afternoon, here came the bride, all dressed in yellow chiffon, topped by a nuptial hairdo that featured a 34-in., hyacinth-entwined coil of hair. Then, slipping a circlet of diamonds on Liz's finger, he she wed. That night, said Liz, "we sat and talked and giggled and cried until 7 in the morning...
...induction coil, two inches long and three-quarters of an inch in diameter, that can be set beside the wire to tap a telephone...
