...Sweeney, who now lives in the U. S. Brother Robert helped the group lay hands on 100 Thompson submachine guns and some Winchester automatics. British authorities let them have ten heavily armored cars, six motorcycles, a quantity of heavy automatic arms and ammunition, radio equipment and a special wavelength. They train with the Scots Guards every weekend, attend evening lectures thrice a week. Strictly outside U. S. law, the new unit was nicknamed "The Gangsters...
There will be no change in wavelength, which will remain at 800, because WHDH is the only interfering station, and goes off the air at eight o'clock...
...sign of woe, fortelling that unemployment will again exceed its "normal" quota of 10,000,000. When the market is down the New Deal begins to look for new brands of unemployment reducers and market restorers. Last week, it was obviously twirling the dial in search of the right wavelength on which to broadcast a new offensive against renewed depression...
Pure science gave way to practical technology when one of Dr. Langmuir's coworkers, Dr. Katharine Burr Blodgett, found that a layer of transparent liquid soap, with a thickness of one-quarter the average wavelength of white light (about 4/1,000,000 in.), made the glass to all intents and purposes invisible. Reason: glass is visible because of the light reflected from its surface; with a soap film there are two reflections, one from the glass and one from the soap; by spacing the two surfaces properly it is possible to get the "crest" of a light wave bouncing...
...bring U. S. television out of the laboratory, engineers have several tough nuts to crack. DuMont's head man, Allen B. DuMont, boasts that he holds the broken shells of three of the toughest. Hitherto each television station has been using six megacycles, almost six times the total wavelength space filled by 745 licensed stations in the U. S. broadcast band. The DuMont transmitter has been reduced to a relatively modest three-mega-cycle sprawl. The DuMont transmitting system is said to throw its pictures well beyond television's paltry 50-mile effective range. This it has done...
