Transistorized Computer. Bell Telephone Laboratories told last week about a large-capacity electronic computer whose essential works occupy only three cubic feet of space instead of a good-sized room. The reduction of size is due to the replacement of bulky vacuum tubes by 800 tiny transistors and 11,000 germanium diodes. All of them together need only 100 watts ) of current, less than one-twentieth of the power required by a comparable vacuum-tube computer...
...Bell TRADIC (TRAnsistor-DIgital-Computer), developed for the Air Force, is intended for use on airplanes, taking over much of the electronic thinking now done by vacuum-tube equipment. Besides being small and light, it generates almost no heat, an important consideraion in the hot, cramped innards of a modern jet plane...
...even more radical flat tube under development by General Electric Co. gets rid of the vacuum, and it has no electron beam either. It consists of a sheet of "electroluminescent" phosphor that glows when it is excited by an electrical voltage. The phosphor is sandwiched between a matrix of horizontal and vertical wires. If there are 500 running in each direction there will be 250,000 points at which wires cross. These intersections can be made to glow by impressing the proper voltage on the wires. If the voltages are changed rapidly, the spot of light scans the screen, forming...
Golden Leaves. Manhattan's Imperial Crown Inc. put on sale gold pins and earrings made by putting trees and plant-grown leaves in a vacuum chamber and forcing 24-carat gold into the pores. The jewelry retains the shape and details of the original leaf, and the company expects to put gold broccoli, parsley, pea pods and strawberries on the market in the next two months. Price for earrings: $4 to $6; pins...
Since bait advertisers calculate that one housewife in three will buy the high-priced model, the pattern is repeated daily in thousands of U.S. homes. In Seattle, vacuum cleaners are popular bait. Radio station KOL advertised a rebuilt vacuum cleaner for $8.95, but a demonstration showed that it lacked the suction to extinguish a match, and the salesman switched to a $120 cleaner...
