...open-hearth process. These furnaces, lined with dolomite (lime and magnesia oxide), are primed with plate scrap and limestone, then charged with pig iron, scrap and ore, and heated. Gas expelled from the limestone stirs the mixture, helps form the slag. A furnaceman spoons out samples, cools them to test quality, then adjusts the heat to get just the quality he wants. After about twelve hours the furnace is tapped, the steel ladled off. The Bessemer process is three times faster than the open-hearth, and correspondingly cheaper; but since the quality of the steel in a Bessemer "heat" must...
Designer Davis' wing, flush-riveted and smooth of contour, had justified his prediction that it would be 20% more efficient than any in the air today. The product of ten years of work, it had been tried in Caltech's aeronautical laboratories and in test rigs of its designer's own devising. Whether he had achieved a smooth flow of air over virtually its entire surface as National Advisory Committee for Aeronautics has done with its new wing curve (TIME, May 15), David Davis modestly declined...
Last week, while 120 of New York's bookies gloomily set up their stools for the opening of what may be their last Belmont Park meeting, the measure met its crucial test, passed the State Senate a second time-in spite of an alleged $100,000 greasing fund put up by bookmakers. Now expected to be passed by the Assembly and approved at the polls next November, pari-mutuels may appear at New York tracks next spring, and an extra $5,000,000 to $10,000,000 revenue is counted on for the State...
...hunch that the immature hearts and blood vessels of epileptics did not supply enough oxygen to their brains. Hence the convulsions. This theory fitted in with the general fact that many epileptics do not have any brain abnormalities which might be considered responsible for the seizures. To test their hunch, the doctors placed 14 epileptic children under the care of a coach, who helped them develop "athlete's heart" through a strenuous program of rowing, running, basketball, football. At the same time the patients were placed on the traditional low-water diet, to dehydrate their brains and allow...
Reason for the small number was given as the fact that it was the second, or intermediate, in a series of increasing difficulty. All of the eleven men had taken the first examination at some time, and a great many of the rest of those who took the primary test dropped out before the prospect of another test and more outside reading...
