They then tried the vapor on eleven cases of infected amputation stumps. Freshly ground onion (potency is lost in about 15 minutes) was applied to the patient so that the onions did not touch the wound. The vapor was held in by layers of gauze. Healing was complete in a month or so, in all but one case...
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...
...from England again last week laced the multiple vapor trails of Eighth Air Force bombers and fighters bound "for Germany. For the Thunderbolts and Lightnings, it was their longest mission yet (over 400 miles out) and a new high in U.S. fighter-bomber relations...
...Greenback ticket, he got 82,000 votes. But he was one of the most wonderful grandfathers who ever lived. His prosperous glue (and gelatin) factory, at Madison Avenue and sist Street in Manhattan, would have made him a fortune even if he had not invented the mercury vapor lamp, built the first American steam locomotive, or helped finance the Atlantic cable. His long white hair reached almost to his shoulders. He shaved himself with a razor used by George Washington. He wore a black frock coat, a black stock about his neck and, when he went visiting...
...Forgery. Cooper Hewitt's favorite discovery was the transformation of polyphase alternating current to direct current through the mercury vapor transformer. He decided suddenly, circa 1910, that "if a path of electric current were established across a tube which had a single negative electrode and multiple positive electrodes, and the positive electrodes were each connected with a different phase of the alternating current, the positive impulses would be conducted successively to the negative electrode which was already in operation with its surface resistance broken down, but the negative impulse could not be transferred to the positive electrode because here...
