Abstract

496,864. Electrodeposition of gold; electric discharge tubes. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.-GES. May 16, 1938, No. 14538. Convention date, May 15, 1937. [Class 41] [Also in Group XL] The grid of an electric discharge tube is electroplated with several thin layers of gold, the grid being heated to about 1000‹ C. in an inert gas after application of each layer to expel gas.
