After declining steadily for a week, livestock prices hit their lowest point in more than four months. The cave-in loosened the prop under retail prices. Most Eastern food chains promptly slashed as much as 19% off some pork prices, 35% off beef. Stores in Cleveland, Detroit, Chicago and points west followed suit, in some cases with even bigger slashes. Dun & Bradstreet's wholesale food price index dropped to its lowest point in 14 months...
Cotton Crutch. Cotton prices, which had been slipping at the prospect of the biggest crop (15,219,000 bales) since 1937, got a prop from the Department of Agriculture. The department agreed to make loans on cotton stored on farms (formerly it made them only on cotton stored in approved warehouses), thus made it possible for farmers to keep their cotton off the market and keep prices...
This is mostly because the "propulsive efficiency" of the jets at ordinary speeds is low compared with conventional airplanes. Propeller-driven planes are pushed forward by the reaction from the blast of air forced backward by the prop. When the plane is standing still on the ground with its propeller roaring, all the engine's effort is wasted on merely moving air. None goes into forward motion; the propulsive efficiency is zero. When the plane is in the air, the propulsive efficiency is high. Propellers are designed in such a way that when the plane is flying at full...
...With his partner, Walter Sharp, he struck oil in the Goose Creek field, but the two-edged "fishtail" bits used in those days broke on subterranean rock. Thereupon Hughes designed a conical bit with 166 cutting edges. That tool is the original source and still the main prop of the Hughes fortune, which now amounts to about $145,000,000. The bit is leased, not sold, and accounts for some 75% of the rock bits used in drillings all over the world. The present Hughes enterprises include Hughes Aircraft at Culver City, Calif.; Hughes Productions (movies); a controlling interest...
Dismayed Her Crew . . . That night at Chicago Stadium he spoke before 20,000 Swedish-Americans who were celebrating the 100th anniversary of Swedish immigration to the Midwest. He pulled out that surefire issue-Communism-and used it as a sort of moral prop for his civil-liberties program, for slum clearance, old-age pensions, and higher minimum wages. The audience was friendly but calm...
