...Composers in both Europe and the U.S. soon learned that in Boston, if nowhere else, their music could get a sympathetic hearing. Nearly every program Koussy scheduled included pieces by such contemporary foreign composers as Sibelius, Stravinsky, Prokofiev and Shostakovich, and such Americans as Aaron Copland, Roy Harris, Walter Piston, Howard Hanson, William Schuman and Samuel Barber...
...Tires & Pistons. Wallard's victory, like most, was won before the race began. Owner Murrell Belanger, a wealthy Crown Point, Ind. auto dealer (Chrysler-Plymouth) and ex-racer who dabbles in the sport for the fun of it, knew that the new "beefed up" (i.e., fatter) tires would produce more speed, particularly on the turns. Belanger also figured that a light, rear-drive car, though it gives a rougher ride, would require fewer fuel stops, that a simple, four-cylinder power plant would require fewer pit stops. As a result, Belanger's aluminum-shelled special turned...
Theoretically a piston worked by a hydraulic press could exert "any desired pressure." However 20,000 atmospheres was formerly the limit, even when using heavy cylinders of heat-treated steel. Strengthening methods can raise this to 30,000 atmospheres, but the piston also reaches its limit at this pressure...
...reach higher pressures, Bridgman made "a radical change in design." To increase the strength of the vessel he made it conical on the outside and pushed it into a conical supporting sleeve; to increase the strength of the piston he made it of Carboloy, which has "a compressive strength of more than twice that of steel." This extended the pressure range to 50,000 atmospheres...
...experimenting with jets; it did not want anything to interfere with engine & plane output. Instead, the Government got the plans of some British jets, turned them over to General Electric and Westinghouse for further development. Result: in the early postwar years, United again was the unquestioned leader in piston engines, but it was years behind in jets...
