Kaleidoscope Console. John Seery, 28, disdainfully tilted a 17-in. color set on its back and imprisoned it in a quartz-like block of plastic. "When the TV stops functioning," explains Seery, "the work is complete." Earl Reiback, 33, an M.I.T.-trained nuclear physicist, stripped the phosphor coating from the glass screens on three sets, allowing the viewer to see electrons gleaming eerily inside the colorfully painted picture tube...
Gabo's sculptures are frequently made from translucent plastic, phosphor bronze or glass; the shape is usually a swooping arc, strung with taut wire or string, like a harp, that forms a delicate open-sided cage for space. Their construction has been likened to architecture, their humming strings to music, their balance to mathematics...
...bouncing off targets, is focused on a semitransparent screen at the front end of an extremely sensitive electron tube. The screen is photoemissive-it gives off electrons when struck by the faintest light. These photoelectrons are then speeded up by high electrical charges so that when they hit a phosphor (luminescent) screen in the tube, they make a much brighter image. The process is repeated three times, until it produces a picture thousands of times brighter than the starlit target viewed by an unaided...
...sixth U.S. maker to manufacture its own color tubes when its new $12 million factory is finished. National Video, the supplier of Motorola's 23-inch color tubes, is spending $4,000,000 to double its capacity. Sylvania has developed a new color tube with a rare earth phosphor that makes it 40% brighter than others on the market. Last week Zenith introduced its new 25-inch rectangular color tube, which shows more of the transmitted picture, and Philco began pilot production of 21-inch color tubes...
