Claim 1
Independent Claim
139 words
IN A SERIES OF ELECTROLYTIC CELLS SUITABLE FOR USE IN THE PRODUCTION OF ALUMINUM BY THE ELECTROLYSIS OF A BATH OF MOLTEN CRYOLITE HAVING ALUMINA DISSOLVED THEREIN, IN WHICH EACH CELL IS PROVIDED WITH A RECTANGULAR CATHODE AND WITH A DOWNWARDLY FEEDING, SELF-BAKING, RECTANGULAR ANODE, AND IN WHICH SAID CELLS ARE DIPOSED IN A FOURCORNER FEED, SIDE BY SIDE ARRANGEMENT, THE IMPROVEMENT IN CONNECTING A PAIR OF PHYSICALLY ADJACENT CELLS ELECTRICALLY IN SERIES WHICH COMPRISES FOUR ISOLATED ELECTRICAL LEADS INTERCONNECTING THE FOUR CORNERS OF THE CATHODE OF THE MORE POSITIVE OF THE PAIR OF CELLS WITH THE CORRESPONDING INGLY DISPOSED FOUR CORNERS OF THE ANODE OF THE MORE NEGATIVE OF THE PAIR OF CELLS, EACH SAID LEAD INTERCONNECTING A DIFFERENT SINGLE CATHODE CORNER AND A DIFFERENT SINGLE ANODE CORNER, WHEREBY EACH CORNER OF SAID ELECTRODES IS FED CURRENT INDEPENDENTLY.
