...waves can be used to dry artificial silk as it is spun out of cellulose and reeled into hollow spools. Dried formerly with heat, the outer fibers would dry first and contract upon the inner ones, causing nonuniform drying and shrinkage. But high-frequency radio waves emanating from an antenna in the center of the reel dry the fibers uniformly, avoid shrinkage...
...torpedo had struck fair on the starboard side. No. 5 Hold filled at once. The Lehigh began to settle fast. The main topmast came down, carrying away the main radio antenna, so that Sparks thought his SOS was not transmitted. All hands manned the boats and pulled away while she sank. All four of the lifeboats were picked up by British vessels within 50 hours...
...building in a scrub-pine clearing 40 miles away. There with the aid of a wafer of quartz crystal vibrating at a constant frequency of perhaps 11,830,000 cycles per second, and boosted by thousands of watts of electric power, the vibrations ripple from a great antenna outward in waves 26 meters long. In no time at all (for their speed is that of light], they reach a point in the darkness 3,000 miles away. A man there has a receiving set in his cellar tuned to the right wave length. He is risking prison or maybe death...
Plunked down in the midst of medieval Andorra, the gleaming steel & stone station is unusual. Because of the technical difficulties of transmitting from the mineral-veined peaks, the 400-ft. pylons supporting the antenna rest not on native rock but upon special copper-bound, earth-filled piers sunk into mountaintop Lake Engolaster, 4,900 feet above sea level. Twenty-three hundred feet below, overlooking the valley, is a modernistic, three-story granite building which houses the control panels and living quarters of the operators. From its dizzy perch Radio Andorra has the strength to make itself easily heard in England...
