...detection system for the Sidewinder missile, which seeks out the enemy aircraft by homing in on the heat from its engines. The company also provided the detection equipment for the surveillance satellite Midas. On the commercial market Infrared Industries offers a toy walkie-talkie that uses an infra-red beam to transmit up to i.ooo ft. in the daytime...
...volt electrons of ordinary microscopes are not powerful enough to penetrate the two layers of film and the plump, water-filled bodies of healthy bacteria. So the upper part of Dupouy's sphere is filled with a powerful accelerator that delivers a beam of million-volt electrons. They are tricky and dangerous to handle, but carefully measured bursts of them pass through living bacteria and make meaningful shadow pictures of their insides, magnified 25,000 times. The bacteria are little the worse for their experience. Dupouy testified almost affectionately that when they are taken out of the formidable microscope...
Tilting a 100-kw. high-frequency radar transmitter 71° into the night sky near Washington, D.C. last April 22, Gallet aimed a radar beam at what he believed to be a pipe that would carry the signal to a point in the South Pacific Ocean just off the southern tip of South America. Two-tenths of a second later, an echo came bounding back-after a round trip of 37,000 miles...
Last week, with three months' worth of successful beam-bending to back them up, Gallet and Professor Booker were considering the practical applications of their theory. In time, they believe, the bent beam may provide: 1) a new tool for studying the effect of solar eruptions on the earth's magnetic field; 2) a new method for long-range surveillance of missile activity behind the Iron Curtain; 3) jam-proof long-distance communications...
...eyes in bookstalls across Latin America are engaging editions of Spanish-language stories about happiness in Red China. Grownups can read more sophisticated magazines and drop in at 16 Red China-run "binational centers" set up in nine South American nations. They can tune to the powerful beam of Radio Peking, which recently jumped its broadcasts to 31½ hours a day in Spanish and Portuguese. Or they can simply turn to their daily papers, spotted with news from the New China News Agency, which often operates alongside Fidel Castro's mouthpiece Prensa Latina...
