Abstract: An arrangement of busbars leads the direct electric current from a transverse electrolytic cell in particular such a cell for producing aluminum, to the anode beam of the next cell. The self consistent magnetic field of the cell is almost completely compensated if, at the upstream cathode bar ends, at least two individual or groups of cathode busbars and connecting busbars lead to a busbar connected to the downstream cathode bar ends or to a riser. A part of the connecting busbar runs completely under the cell at the middle; the other part likewise runs under the cell until it is in the region of the longitudinal axis (L) where it follows this axis until it projects out beyond the end wall of the cell, and finally runs along the cell.

Abstract: The present invention relates to an anode support system for supplying electric current to a molten salt electrolytic cell wherein a pronounced reduction or suppression of the metal wave in the cell can be achieved without increasing the interpolar distance between the metal wave and the above lying anode.The anode support system, which may comprise two horizontal anode beams which are joined together at the ends by conductor plates, is separated at least at two places and joined up again in a mechanically stable manner by means of an electrically insulating material. If the anode support system is made of a single piece then it is separated at least at one place over its whole cross section and joined up again by an insulating joint.The electrically insulated sites can be bridged in parallel by switches.

Abstract: The electric current leaving an electrolytic aluminum reduction cell leaves the long sides of the cell via cathode bars connected to at least four asymmetrical busbars which lead to the anode beam of the next cell. These busbars which lead the current off in opposite directions are arranged on both sides of the cell at various distances, whereby however, the distances of two diametrically positioned busbars from the central axis of the cell are equal.

Abstract: Method of protection of electrically conducting parts in fluoride melts through which direct current flows in the electrolysis of aluminum oxide, comprising applying such an electrical potential to said parts that the direct current flowing through the fluoride melt cannot emerge from the parts at any place within the fluoride melt.
