Radioactive isotopes are taking jobs in peacetime industry. Last week the California Research Corp. (a subsidiary of Standard Oil Co. of California) and the Atomic Energy Commission told now radioactive piston rings are being used to test the performance of lubricating...
Last week the Air Force announced that it has developed and tested two rockets that are really guided. One, the NATIV (North American Test Instrument Vehicle), is a small contraption 13 feet long, designed for high-speed aerodynamic studies. The other, the 774, looks like a formidable weapon (see cut). It is 32 feet long (the V-2 was 45 feet long), and, says the Air Force, "is potentially capable of attaining altitudes of more than 100 miles...
When a labman wants one of the dangerous rings, he takes it out of the cave on the end of a three-foot stick. Working carefully, with special tools, skilled mechanics fit the ring onto the piston of a test engine. After the engine has run for a few hours, its lubricating oil becomes radioactive because of "hot" iron rubbed off the ring...
...leveling-off process, noted across the land, showed signs last week of also slowing down new wage raises. In the year's first major test of fourth-round demands, the C.I.O. Textile Workers Union lost its fight for a 10? increase in the New England cotton and rayon industry...
...workings of the machine are fairly shuple. A stencil is placed over the test paper which covers all spaces except those where correct answers are supposed to be marked. Both the test paper and the stencil are then placed in a slot up against a panel of thick copper pins. When the machine is turned on, the pins pick up all pencil marks that show through the spaces in the stencil, because pencil marks made with special pencils, conduct electricity. The rest is simple. The machine just "counts" the number of electrical impulses and then stamps it on the exam...
