  • Apparatus for the precise adjustment of the anode plane of an electrolysis cell used in the production of aluminum
    Patent number: 4465578
    Abstract: An apparatus for the precise adjustment of the anode plane of a cell for the production of aluminum by electrolysis of alumina dissolved in the molten cryolite of which the anodic system comprises a plurality of prebaked anodes arranged in two parallel lines and provided with suspension rods connected electrically to an anode bus bar which permits the positive intake of current.
    Type: Grant
    Filed: November 17, 1982
    Date of Patent: August 14, 1984
    Assignee: Aluminium Pechiney
    Inventors: Daniel Duclaux, Roger Boinet, Jean-Louis Gerphagnon, Jean Baghe
  • Process and apparatus for collecting the fumes given off during the production of aluminium in an electrolysis cell with a continuous anode
    Patent number: 4051224
    Abstract: The invention relates to a process and an apparatus for collecting the fumes given off during the production of aluminium in an electrolysis cell with a continuous anode.In the process, the surface of the electrolysis bath is closed, on the one hand along the long sides of the cell, by a longitudinal panel which is applied in fluid-tight manner to the anode tube, leaving an air intake free at its base, and on the other hand along the short sides of the cell by a fixed hooding closed laterally by the longitudinal panel.The invention is applicable to cells for the igneous electrolysis of alumina comprising a continuous anode.
