(USA) Since the oxide bond of usual glass-to-metal seals is deteriorated when exposed to alkali-metal vapours at high temperatures, direct glass-to-metal seals have been developed for use in vacuum tubes containing alkali vapours. The report describes the techniques used to construct such seals. The metals used were tungsten, molybdenum, kovar, Chromallized molybdenum and Kovar and chromium plated molybdenum. The glasses were Coming 7740,7720,3320,1720,7052 and 7056. The report describes the cleaning techniques of the wires (0.040 in. diameter) the beading techniques of the wires, and the manufacturing technique of nine-pin presses.
