...Because the large currents that flow in superconductors generate the intense magnetic fields needed in atom smashers and in controlled fusion experiments, superconductors will eventually replace bulky elecromagnets in these areas. A 1-lb. superconducting magnet cooled by a 200-lb. refrigerating system and powered by a 6-volt battery can produce as intense a magnetic field as an iron-core electromagnet weighing several tons and requiring 50 kilowatts of power. Entire trains could be suspended above their roadbeds in strong magnetic fields produced by superconducting magnets, enabling them to travel more smoothly and with less friction at speeds over...
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...
