Ultrafax, by RCA out of Eastman Kodak Co., is a hybrid variety of facsimile transmission. It combines features of both television and photography. The material to be sent (text, writing, pictures, diagrams) must first be photographed on a strip of movie film. Using a kind of modified television technique, the film is "scanned" by a "flying spot" of light. At the receiving station another flying spot reproduces the material on another strip of film. When Ultrafax is really rolling, said Sarnoff, it can transmit 1,000,000 words a minute...
...other big manufacturer of piston engines, Curtiss-Wright Corp., is making a hybrid (for the Navy) on a different plan. Its Turbo-Cyclone 18 is a regular, 18-cylinder piston engine whose exhaust drives three turbines geared directly to the crankshaft. The energy recovered gives the engine more horsepower with over 15% more fuel economy...
This week the Air Force released a rather sketchy description of a sort of hybrid of the old & new: Pratt & Whitney's Wasp Major-VDT. Basically, it is the 28-cylinder, 3,500-h.p. Wasp Major used in the Air Force's B50 bombers. Combined with a "variable discharge" turbosupercharger manufactured by General Electric Co., it turns into a new engine with greatly increased power and flexibility...
...discharge opening can be varied in size to get the best division of exhaust energy between supercharging and jet thrust. The result is an engine with 4,000 (instead of 3,500) h.p., without proportionate increase in weight. The Air Force intends to use the hybrid in its newest heavy bomber...
Today, after false starts and heavy going, Rockefeller has four projects (besides the mechanization company) that can argue for themselves. On an 867-acre hilltop farm near Jacarezinho, a mixedcapital company has completed its 32nd cross of Brazilian seed corn, has harvested 32 tons of high-yielding hybrid, and sold the lot to Parana and São Paulo farmers. For the world's third largest corn producer, the possibilities of hybrid were scarcely less revolutionary than they had proved for Iowa...
