...tables, porcine movie producers discuss deals over an aperitivo, sad-eyed young English poets finger their last published articles, handsomely tailored young men while away their time, expertly assess the jewels on neighboring matrons and debate whether to offer their services as escorts. Sauntering by in an endless stream are pretty, dark girls with swelling bosoms and swelling hopes of catching a producer's eye, gawking tourists from Germany, Switzerland or the U.S., or uninhibited Italian families who stop to stare, and sometimes guffaw...
...powerful and presumably loudest jet engine, the Pratt & Whitney J-57, is working on ways to reduce its roar to a tolerable level. One method worked out by Engineers John M. Tyler and George B. Towle utilizes the fact that the frequency (pitch) of the noise generated by a stream of gas varies with the stream's diameter. The big stream that shoots from the tailpipe of a jet engine stirs up a lot of low-frequency sound that carries for miles as a thunderous roar. Small gas streams, e.g., air escaping from a compressor hose, give high-frequency...
Tyler and Towle first tried shooting the engine's stream of hot gas through a sheet-metal plate perforated with small holes close together. This did not work very well. The wakes of the little jets of gas acted upon each other and caused violent turbulence that made too much noise of its own. Next they added to the tail pipe a metal cylinder with holes all around and closed at the rear end with a metal cone. It worked well in reducing noise level, but since the gas jets pointed every which way, the engine lost nearly...
...flight. For actual installation in airliners, it will be made of several telescoping cylinders fitting around the tail pipe, and a segmented cone that can be closed or opened. When the airplane takes off within earshot of neighbors, the cylinders will be extended and the cone closed. The mighty stream of hot gases will be broken into small and comparatively quiet jets. After the aircraft is high in the air, the cylinders will be drawn back into the engine's nacelle and the cone will be opened. Then the engine will have full thrust for economical cruising...
Gypsy Blessing. But as dedication day approached, excitement steadily mounted in Ronchamp. A steady stream of famous visitors had replaced the villagers' early doubts with growing pride. Said Dominican Father Regamey, whose order sponsored Matisse's chapel at Vence: "Le Corbusier's modulated chapel in reinforced concrete is hard and soft at the same time, like the Gospels." Swiss Architect Hermann Bauer praised it as "more like sculpture than a work of architecture." A band of gypsies, adept at mind reading, decided they liked the new chapel "because of its pure form and white color." Even...
