Abstract

471,636. Obtaining high vacua. GENERAL ELECTRIC CO., Ltd., BENJAMIN, M., and WRIGHT, D. A. Sept. 11, 1936, No. 24828. [Class 8 (i)] [Also in Group XL] For the removal of residual gases from a vacuum vessel, e.g. a thermionic valve having an external anode, barium is dispersed by heating within the vessel to a temperature of 1200‹ C. a tungsten wire coated with an equimolecular mixture of barium and strontium oxides.
