...aluminum disc of earlier experiments. It was a sheet of nickel 1/2000 of an inch thin and three inches in diameter, supported against the 100-pound suction of the vacuum tube by skeleton struts of molybdenum. The molecular structure of nickel is such that molecules of air (oxygen, nitrogen) cannot pass through it, though it offers a minimum of resistance to those billionth parts of molecules, electrons...
...find a combination that did not give them "caisson disease" or "the bends," as divers call the dangerous condition produced when they are brought too swiftly out of high-pressure depths. The basis of this dangerous condition is the formation of bubbles in the blood stream, bubbles of nitrogen that has not escaped fast enough from solution in the blood...
Helium, which goes out of solution far more swiftly than nitrogen, and is just as inert chemically, promises to serve as an efficient substitute for nitrogen as the 79% inert diluent of oxygen in a diver's breathing atmosphere, and to permit longer work at greater depths...
...payment of $136,330,000 on the present dam No. 2 during the 50-year lease, or of $181,348,000 if dam No. 3 is also built. It allows the Government to take over the equipment in time of war. It guarantees 10,000 tons a year of nitrogen fertilizer in three years, 20,000 tons annually in six years and 40,000 annually in eight years. The last 20,000 tons of this production is predicated on the previous sale of the smaller output. Profits on the fertilizer are not to exceed 8%, and a farmers' board...
...Miethe of Berlin and Professor Nagoaka of Tokyo have claimed they obtained gold from mercury. Mercury was bombarded with streams of electrons from an X-ray tube at 140,000 volts, but not so much as one part of gold in a hundred billion of mercury was afterwards detected. Nitrogen bombarded with helium atoms going 12,000 miles an hour was built up into fluorine atoms, which then disintegrated into atoms of hydrogen and oxygen...
