...December Ying perfected a method of determining the temperature distribution of vortexes. Since the flame wiggles, a simple thermometer was of no use, so Ying and Emmons swung a long tungsten live wire through the flame. In this way they obtained data which could be plugged into a computer program to give the temperature distribution. Ying discovered the highest temperature, 3200 degrees Farenheit, several inches from the center of the whirl...
...engine tested in a 30-minute, 3,200-mile flight over the Pacific got its thrust by passing vaporized cesium metal through a hot tungsten filter. This action strips electrons from the cesium, speeds the positively charged ions out the rear of the engine. The great advantage of this process is that it requires remarkably little fuel-only one-tenth of that for a conventional chemical rocket. Even the smallest ion engine could keep a satellite on its right course for more than ten years by giving it gradual nudges. On a 300-day trip to Mars, a full-scale...
...high-temperature nuclear reactor designed to melt its way into rock. The reactor is 2 ft. to 3 ft. in diameter, and its active material (uranium oxide) is enclosed in a cylinder of beryllium oxide, which serves as a heat insulator. The lower point, mostly tungsten, is heavy, while the upper point, mostly beryllium, is light...
...pioneered the use of micropaleontology (the study of fossils) for finding oil with the 1918 strike at the Desdemona field in Texas, later in Washington spearheaded the wartime campaign to make the U.S. self-sufficient in vital materials that led to the discovery of substantial domestic deposits of vanadium, tungsten, manganese and other valuable ores; of a stroke; in Washington...
...squash team, is studying ways to reduce underwater boundary-layer drag on submarines, for example. Others are pondering modern Argentine history, the future use of lasers in naval gunnery, the effect of radiation on transistors, the accuracy of navigational methods, and a potential heteropoly acid combining gallium and tungsten. The young scholars range far off base, from the Bell Telephone labs to a nuclear sub cruise...
