Ultrasound, as the practitioners of a new and arcane art call it, refers to vibrations above the limit of human hearing (about 20,000 cycles per second*) In industry ultrasound waves are used to precipitate carbon and sulphur from chimney exhausts, abating the smoke nuisance and recapturing useful materials, and for testing big metal components such as locomotive axles for flaws. In dentistry there is the ultrasonic drill. In medicine a few enthusiasts have reported good results with ultrasound in arthritis, neuritis, muscle spasm and athletic injuries. It will break up gallstones or kidney stones in an animal...
Most people think of fuel as something that gives off heat when the carbon in it combines with oxygen from the air. Chemists have wider horizons. A fuel means any combination of substances that reacts chemically with a release of energy. The ingredient that "burns" may be a metal or a compound containing a metal. The "oxydizer" may be oxygen-rich, or it may have no oxygen at all. The test is the yield of propulsive energy, which scientists measure as "specific impulse...
...high-energy hydrogen in easy-to-handle form. Modern boron fuels are stable, reliable and have high (classified) specific impulses. One of them is now being manufactured in considerable quantity by Olin Mathieson Chemical Corp. at Niagara Falls. Gallery Chemical Co., near Pittsburgh, is making its HiCal, a boron-carbon-hydrogen combination...
...Pretty, smartly gowned Mrs. Robert North, 37, now secretary of the American Chamber of Commerce in Thailand, who went there as the wife of a Hollywood screen writer in 1950.

...Style Water. Workers and scientists in protective clothing played streams of carbon dioxide into the cooling channels, but the fire in the uranium did not go out. Police were alerted to evacuate the area, as scientists debated whether it would be safe to put out the strange, new-style fire with old-style water. The decision was made to go ahead, and hoses poked into the reactor soon put out the fire. The alert was canceled, and the single casualty, Worker Stan Ritson, who got unpleasantly radioactive, was scrubbed over and over and sent home with all his body hair...
