...Reaction Motors, which has concentrated heavily on research since its founding in 1941, is just getting into mass production. Reaction made the first 350-lb. thrust engine for World War II's experimental Gorgon flying bomb, built the liquid fuel engines for Bell's X-1 series rocket planes. Currently, Reaction is at work on a rocket booster for a U.S. Air Force plane, has a contract to produce rockets with 500,000 Ibs. of thrust for supersonic Air Force test sleds. Another project: the rocket engine for North American's piloted X-15 rocket plane, which...
...Liquid v. Solid. Watching the figures soar, dozens of big companies are hurrying into the field to share the bonanza. General Electric, after a start in small rockets, is now producing the big (100,000-lb. thrust) first-stage rocket for the Vanguard earth satellite. Curtiss-Wright is producing small antitank rockets for the Army, is working on a throttle-equipped" rocket engine for planes and missiles. Bell Aircraft, Hercules Powder, Phillips Petroleum, General Motors and many others are developing new engines and materials to fuel them...
...fast the rocketmen fly depends on how soon they learn to produce better fuels to power their engines. The great debate in the industry today, much like the old argument over air-cooled v. liquid-cooled engines, is over solid rocket propellants v. liquid rocket propellants. Most big rockets, including both Intercontinental and two of the three Intermediate-Range missiles, now use liquid fuels with an oxidizer such as nitric acid or hydrogen peroxide. Liquid systems have produced the highest thrust-weight ratio (80 Ibs. for each i Ib. of weight), but they require an enormously complex system of tanks...
...green peas keep their shape but become as light as miniature ping-pong balls. Freeze-dried chicken breasts look like balsa wood. For gourmets, freeze-dried foods offer some interesting possibilities. Chicken or fish could be made to soak up several times their weight of wine or other flavorsome liquid...
Chemical Memory. Some of these applications promise to grow into important businesses, but the Cash research men have long since taken off into wilder blue yonders of capsule science. Most interesting capsules produced so far are filled with a liquid photochromic dye that turns blue when exposed to light of a certain wave length and loses its color when light of another wave length hits it. The Cash men are hard at work building these talented capsules into a "chemical memory" for computing machines. A transparent film impregnated with photochromic capsules can be written upon in coded dots of color...
