Abstract
501,892. Carrying conductors through partitions. BERGHAUS, B. July 11, 1938, No. 20547. Convention date, July 9, 1937. [Class 36] [Also in Groups XI, XXXV, and XL] An electrode 9 is mounted through the wall 1 of a metal chamber by a clamping ring 34 which compresses a rubber seal 32 between insulators 31, 33. The electrode is hollow to receive a cooling fluid and is surrounded by a metal sleeve 38 screwed into the wall.
