摘要： An improved method of manufacture for electrolytic cathode devices that include a copper hanger-bar with a rounded underside that ensures the automatic vertical positioning of the cathode's blank starter sheet with respect to horizontal supporting bus-bars irrespective of warpage or construction defects. The mechanical connection between the hanger bar and the starter sheet is achieved by inserting the latter's upper edge into a receiving groove in the underside of the hanger bar and by welding the entire length of connection, thereby establishing a large boundary surface for good electrical conductance. One embodiment of the invention also features notched lateral edges that increase the rigidity of the starter sheet and allow the ready installation and removal of conforming insulating strips.

摘要： An electrolytic cathode consists of a solid copper hanger bar and a stainless-steel mother plate attached to a receiving groove in the underside of the hanger bar. In the preferred embodiment of the invention, the entire length of connection is welded, thereby establishing a large boundary surface for good electrical conductance. The solid hanger bar further includes a cladding of stainless steel wrapped over the copper bar and the upper portion of the mother plate, leaving only the ends of the copper bar exposed for electrical connection with conventional bus-bars. The lower edges of the cover are attached to the mother plate by a steel-to-steel weld that produces a strong and durable connection. The lateral edges of the cover are also connected to the copper bar by a conventional copper weld that completely seals the cover over the copper bar, thereby preventing contamination from the electrolytic solution. The cover is then welded to the mother plate and sealed around the copper bar. The heat produced by the welding process, which causes the steel cladding material to expand during welding, is used to improve the tightness of the fit between the cover and the copper bar as a result of the cover's shrinkage occurring during cooling.
