Abstract

193,628. Preston, L. G., and Hodgson, B. Jan. 24, 1922. Vacuum tubes.-The leading- in wires and metallic supports for the electrodes are shielded from the discharge so that conduction takes place wholly or almost entirely between the electrodes. The supports B and lead A for the ancde C are mounted in tubes T extending nearly up to the anode. The filament leads D are protected in a similar manner, and a tensioning support E may be enclosed in a tube T'. Insulating petticoats P may be provided on the tubes.
