...Field in a 1929 Curtiss-Robin monoplane with an old Wright J-6 motor that could turn up only 95 miles an hour. By modern standards the ship was a crate, but in it, with nothing to fly by but a compass, a bit of a map and the beam in his eye, 31-year-old Douglas P. Corrigan of Los Angeles had flown the 2,700 miles to New York nonstop. A vacation trip, he said, and a fairly pleasant one, from his job at the Northrop Corp. aircraft works at Inglewood, Calif...
...Hughes plane's KHBRC signal thundered down the ship's wake into Ground Radio Chief Charles Perrine's receivers at Flushing, L. I. In the plane, Radio Engineer Richard R. Stoddart adjusted the length of the trailing antenna, controlled at will the direction of the radio beam he was transmitting. He had achieved in the design of his transmitter an efficiency formerly impossible in airplane radio...
...expected to sell for its exclusive coverage from 30 to 75 minutes of air time on its Red and Blue networks, had mustered 146 stations from Boston to Honolulu, had a beam open for Portuguese short waving to Brazil, another for Spanish reporting to other South and Central American listeners, a third to carry the German account to Challenger Schmeling's homeland. It was to be the biggest sport broadcast ever...
...which Robert Williams Wood is now doing is the manufacture of diffraction gratings. A diffraction grating is a plate of glass, metal or metal-on-glass on which a series of very fine, parallel lines are ruled close together. In combination with lenses, such a grating breaks up a beam of mixed light, such as the light from a star, into its component wave lengths-that is, it furnishes, as a prism does, a spectrum of bright and dark lines which identify the fundamental elements of matter. The iridescence of mother-of-pearl is a diffraction effect, caused by numerous...
...heart of "Johnny" Green's invention is his use of a tiny beam of light and a photo-electric cell. Whether in the transmitter or in the linotype activator, the light is focused on the coded dot combinations and reflected into the photocell. The varying combinations cause correspondingly varying pulsations in the photocell. These pulsations actuate the appropriate mechanisms in the telegraph printer and in the linotype (or Intertype). Its inventor claims that the speed of the Semagraph is limited only by the speed of the linotype. The number of teletype printers that can receive Semagraph copy from...
