Abstract

220,498. Edison Swan Electric Co., Ltd., and Black, T. C. Oct. 10, 1923. Vacuum tubes.-A valve of the plug-in type is arranged so that the filaments cannot be connected even momentarily across the fixed high-tension terminals. For this purpose the filament terminals 1, 2 are of different length, and both are shorter than the anode and grid terminals 3, 4.
