...capsule of cobalt-60 (cost: $50) will cast its X-ray beam through metal welding, will easily show up every flaw. This inspection process, too expensive with old-style X-ray machines, increases the welding safety factor, reduces the thickness of metal that need be used. Example: if all welds are inspected with CO-60, a 50 ft. "Horton sphere" for storing high-pressure gases can be built safely with 12% less steel at a saving...
...conference of the International Council of Scientific Unions in London, Sterling P. Newberry of the General Electric Co. last week told about the invention of an instrument that scientists have coveted for years. It is a new X-ray microscope, developed by Newberry and Selby E. Summers at the G.E. laboratory in Schenectady...
Scientists have never been able to get a magnified X-ray look at internal structures through ordinary optical microscopes, since X rays cannot be focused by optical lenses like ordinary light. The best X rays can do is to cast shadows of the objects that they have passed through...
Usually, the shadows are ill-defined because the source of the X rays is comparatively large (e.g. as in an X-ray chest plate). As the source grows smaller, the sharpness of the shadows increases...
Ever since the Republicans gained a majority on the National Labor Relations Board, they have taken small steps to limit their jurisdictional boundaries. The board, said Commissioner Philip Ray Rogers, should not poke into labor squabbles involving hot-dog stands, service stations, apartment houses.
