Abstract

516,898. Cleaning by electrolysis. SIEMENS & HALSKE AKT.-GES. July 12, 1938, No. 20688. Convention date, July 21, 1937. Addition to 508,075. [Class 41] In a process for cleansing the surface of etched electrodes, particularly electrodes for electrolytic condensers, as claimed in the parent Specification, the electrode to be cleansed, preferably in the form of a continuous strip 1 is passed through the cleansing bath while completely surrounded by an osmosis diaphragm, such as a tubular diaphragm 4 stretched on a frame of hard rubber, wood or artificial resin. Anodes 3 are mounted close to the diaphragm on either side, the strip 1 being connected as cathode.
