Morse's group solved this problem by making large, high-powered versions of a diffusion pump invented by General Electric's Physicist Irving Langmuir. The diffusion pump works by blowing a strong jet of mercury or oil vapor into the neck of the vessel to be emptied. The vapor stream traps air molecules and sweeps them out through a series of locks. With this equipment, Morse got down to a working vacuum of one micron (a thousandth of a millimeter...
...perhaps the calmest burst of amazing prophecy on record, General Electric's famed Physicist-Chemist Irving Langmuir recently predicted that man would some day speed up to 5,000 miles an hour in a vacuum tube. He thought it would be perfectly possible to build an airtight vehicle, magnetically suspended in the tube and electronically controlled, in which travelers might zip from New York to San Francisco in an hour...
First Sergt. Morris Isacowitz, who served as master of ceremonies and was described by Sergt. Seigle as "the best ` first sergeant in the army," introduce Lieut. Nelson T. Headley and member of the faculty, who were guests, include Dean Fox and Professors Pratt, Estor Langmuir, and R. H. Matthewson...
...Irving Langmuir (1932), General Electric chemist, dour, hard-working student of high vacuums and surface tensions, largely responsible for modern electric lights...
...first ventured only a gingerly toe into the unknown water of industrial research. When he found that he really had a free hand, he took on the G. E. experiment as a full-time job. Things began to hum. The basic experiments of William Coolidge on tungsten, of Irving Langmuir on gas-filled (instead of evacuated) bulbs led to modern electric lamps. The Coolidge and Langmuir experiments also produced high-power X-ray tubes, portable X-ray sets, high-capacity electronic tubes...
