Cruising endlessly under water, the Navy's subs have a private atmosphere all their own in which a single supply of air is breathed again and again. Whenever the oxygen level gets low, huge high-pressure cylinders of oxygen refresh the air, and there is also an electrolytic cell that turns sea water into oxygen and hydrogen, shooting the latter out of the submarine. For emergencies, the Naval Research Laboratory has provided ingenious "candles" made of sodium chlorate and powdered iron. When they are ignited, they emit oxygen, not the carbon dioxide that is given off by ordinary candles...
...Dust. Oxygen alone is not enough. As the crew breathes, it contaminates the air with exhaled carbon dioxide. In older subs the way to get rid of it was to absorb most of it in a caustic such as lithium hydroxide. The nuclear subs must have a far more elaborate system: secondhand air is passed through a liquid containing monoethanolamine, which absorbs carbon dioxide at room temperature, is then heated, and releases the gas so that it can be piped...
...such giants as General Dynamics Corp.'s Convair, North American Aviation, Inc. and General Electric Co., Acoustica won a contract to develop and produce a crucial system for the Air Force's Atlas ICBMs. Acoustica devised a series of ultrasonic sensors to measure the level of liquid oxygen and kerosene in the Atlas...
...government that had so long scorned Boris Pasternak, now gave grudgingly of its best to save him. An oxygen tent was rushed to rambling, weatherbeaten Dacha No. 6 in Peredelkino, 15 miles from Moscow. Professor Nikolai Petrov, a cancer specialist from the Kremlin clinic, strove desperately to win a few more hours from eternity with another blood transfusion. Pasternak asked wearily: "Is it necessary...
...Violent Instrument. Essentially, a shock tube is a strong-walled metal pipe, a few inches in diameter, from which the air can be pumped. At one end, a section is walled off by a copper diaphragm: that section is filled with an explosive mixture of oxygen and hydrogen. At the other end is a vacuum tank, and just ahead of it is a tiny nose-cone test model. When an electric spark explodes the oxygen-hydrogen, it bursts through the diaphragm and into the vacuum. Ahead of it rushes a hot shock wave that hits the test model at actual...
