...successfully demonstrated it for the first time this June. Subsequent experiments uncovered a few problems, though none seem impossible of solving in the construction of a full-scale sub. Electric current passing through the water between the electrodes produces some electrolysis; molecules of water break down into hydrogen and oxygen, which rises to the surface in the form of gas bubbles that could signal the sub's presence below. Swimmers who guided the sub felt a tingling but harmless sensation caused by the electric current. "It is almost exhilarating," explains...
...merely to broaden markets, but to replace costly old plants with automated new ones, or introduce some of the refinements of the research and development on which business spends $24 billion annually. The steel industry will lay out $2 billion this year, much of it for basic oxygen furnaces, continuous casting mills and other new technology rather than to increase capacity...
...trick is the same used by air travelers and skin divers to clear their ears on descent. It also has much the same result as a dose of nitroglycerin or amyl nitrite. Both drugs are rapid dilators of the coronary arteries, and thus quickly increase blood flow within the oxygen-deprived heart muscle; the technique of blowing hard against resistance may work similarly, but, according to the Journal authors, the mechanism is not clear. The Valsalva maneuver should only be used in emergencies. It can be harmful in heart patients with acute attacks, severe high blood pressure, or a history...
Died. Nicholas Piantanida, 33, U.S. parachutist, who tried last May to make a free-fall jump from 125,000 ft., was injured when his oxygen system failed during the balloon ascent 57,000 ft. above Minnesota and emergency efforts to get him down did not prevent 31 minutes of oxygen starvation, causing brain damage and a coma from which he never awakened; of cardiorespiratory failure; in Philadelphia...
...undertake the financing of the memorial, and only two years ago was St. Louis-born Sculptor Walker Hancock taken on to finally finish the grandiose project. There is not likely to be any further delay. Today drillers, directed by walkie-talkies, are using jet torches that burn a kerosene-oxygen mix at 3,500° F. and can slice away as much granite in a day as Borglum's stone chippers could accomplish in three weeks...
