...Juice. Dehydrated like blood plasma (which is frozen, dried under vacuum), a new powdered orange juice preserves both the orange flavor and the valuable vitamin C (ascorbic acid). Reported one sampler of the powdered juice mixed with water: "The color is the same, the texture is the same as strained orange juice-even to the tiny particles clinging to the side of the glass." Developed by California Food Research Institute, the process is approaching the commercial stage...
...Ford, dolomite is powdered, calcined (burned in a kiln) and mixed with ferrosilicon-an electric-furnace product of silicon and iron long used in steelmaking. The mixture is pressed into briquettes and charged into furnaces. When these are heated under vacuum, magnesium vapor is given off, and it crystallizes as on removable steel sleeves...
...commission be appointed by Cordell Hull, Herbert Hoover and Congress. But it was significant for a broader reason: it was a definite break from the isolationist ranks. Said the man who once opposed any foreign intervention: "Neither our foreign policy nor our domestic economy can operate in a vacuum after the war. . . . We must make neither the mistake of fashioning international programs without regard to our American destiny, nor the error of focusing attention upon American problems without regard to their workability in the world in which we live...
...Jack McCullough puts it now, "We didn't know what couldn't be done when we went into the business so we went ahead and did it." He is also modest about Bill Eitel's and his first experience with making vacuum tubes (when Heintz & Kaufman turned them loose on an order for some from an R.C.A. competitor). "Bill burned his fingers a little and broke a lot of glass," says Jack, "but he finally came out of the basement with a vacuum tube...
...time Bill and Jack got through experimenting in their meat market they had come out with something the engineers said was impossible: a tube in which a high vacuum is created, without the aid of special chemicals and maintained by the tube elements themselves. Though radio engineers in 1934 thought 3,000-4,000 watts was the top power for vacuum tubes, "Eimac" tubes are now capable of power peaks up to 1,000,000 watts-yet their cost is extraordinarily low. Even at the beginning Jack and Bill sold 2,500-watt tubes to incredulous airline ground stations...
