...item which Jahco thinks has turned the trick is a two-cylinder, 30-h.p., air-cooled engine for light cars. Designed by Vice President Ralph Heintz, the cylinders, cylinder head and crankshaft are die-cast from aluminum alloy. The engine weighs 175 pounds less than similar engines, yet produces the same power. Jahco expects to make four-and six-cylinder models for planes and boats...
...Caribbean last week was the first of a new class of monster aircraft carriers, the Midway - the U.S. Navy's and the world's mightiest warship. As a fighting machine, the Midway seemed to have everything: her flight deck was armored; thousands of tons of alloy steel encased her vitals; she had 200,000 h.p. to drive her 45,000 tons (60,000 or more at full load) at better than 33 knots; in her new, long-barreled 5-inch guns there was fire power to keep an enemy away while 120 planes operated from her roomy...
...beam, becomes dangerously radioactive. The rays knock neutrons out of silver atoms, turning them into an unstable silver isotope, which breaks down into cadmium, giving off powerful streams of electrons. Some silver, too, is turned into palladium, while some of the copper in the coin's alloy is turned into atoms of nickel.* The betatron is controlled from a neighboring room...

...brand-new and radically different Superfortresses. Gradually, sometimes by means mystifying to zealous ground crews, the bugs began to come out. Sample exterminations: ¶ The B-29's big engines were exploding when they caught fire. Dr. William J. Crozier, a Harvard physiologist, suspected that the magnesium-alloy parts blew up when they were doused by the carbon dioxide in the automatic fire extinguishers. Tests proved him right, and combat crews were immediately instructed to use their extinguishers at the first slight hint of fire, or not at all. Later, aluminum alloys were substituted for the magnesium-alloy parts...
