Supervising the Pilot. In Manhattan, American Airlines disclosed that Astrolog recorders would soon be installed on 20 of its BAC-111 jets. Converting electrical impulses from transducers at tached to the plane's instruments and equipment into 0-to 5-volt signals, Astrolog will record them on a tape that will be fed into a computer. From the data, the computer will define such indi cations of pilot performance as bank angles, speed in turbulence, sink rate and even use of the public-address sys tem. It will also spot any unsafe maneuvers or actions and print out "exception...
...reduce X-ray emissions of high voltage tubes to safe levels, manufacturers equip the tubes with metallic shields that absorb most of the radiation. But because of a manufacturing error, the shields inside many of the 24,500-volt G.E. tubes were misaligned. As a result, part of the X rays emitted by the anode could leak through the bottom of the tube. The radiation from the tube, according to the Public Health Service, ranged from ten to 100,000 times more than the rate considered safe...
...failure crippled nearly one-third of the 48,000-sq.-mi. area served by the Pennsylvania-New Jersey-Maryland Interconnection, a power grid serving those three states plus Delaware, Virginia and Washington, D.C. It began in southeastern Pennsylvania, when a 230,000-volt power line abruptly surged with 606,000 kilowatts. The overloaded line heated up and cross-circuited with a low-voltage line. The Philadelphia Electric Co. had twice warned system dispatchers to anticipate a heavy load and split it between two lines, but the orders, for some reason, were disregarded. The short circuit automatically shut down Philadelphia Electric...
Distant Music. The 64,000-volt question about the use of light as a medium is, of course, whether it can produce great works of art or will remain merely intriguing decoration. Certainly luminal art is dazzling, far more mysterious than the jeeringly antisocial comment of pop, far more alive and sprightly than two dimensional op. Yet, like op, it often seems to be all surface and no content. In part, the problem lies in the novelty of the art and the difficulty its practitioners find in rising above the welter of technological gimmickry. But, unless some way is found...
Called the Markette, Westinghouse's boxy little (1,730 Ibs.) electric car will carry two passengers at speeds up to 25 m.p.h. Its twelve conventional six-volt lead-acid batteries will drive it for 50 miles at a cost of about 10 a mile, can be recharged in eight hours through a cord plugged into ordinary house current. Many motorists may balk at joining the Westinghouse rebellion, since the car, which will sell for "under $2,-000," will need $300 worth of new batteries every two years. Still Westinghouse claims that it already has orders in hand...
