  • Patent number: 4380493
    Abstract: A lead anode for electrowinning cells in which the anode is in the form of rods reinforced with a core of titanium or other strengthening material.
    Type: Grant
    Filed: November 10, 1981
    Date of Patent: April 19, 1983
    Assignee: IMI Kynoch Limited
    Inventors: John P. A. Wortley, John Woolner
  • Patent number: 4319977
    Abstract: Electrode, particularly an anode, for use in electrometallurgical cells in which the electrode is formed of two very thin sheets of titanium which are corrugated and arranged in a mirror image position, being spot welded where they touch each other and being spot welded to a titanium sheathed hanger bar. The electrode, which is particularly suitable as an anode, can be formed from very thin titanium and has enhanced stiffness resulting from the corrugations which strengthen the overall construction.
    Type: Grant
    Filed: April 23, 1980
    Date of Patent: March 16, 1982
    Assignee: IMI Kynoch Limited
    Inventor: John P. A. Wortley
  • Patent number: 4129492
    Abstract: An electrolytic cell, particularly one for use in the production of foil, in which the cathode comprises a rotating drum having a conforming anode spaced therefrom with a melded fibre interlayer. The interlayer remains stationary while the drum rotates over the fibrous surface, thereby breaking up the depleted barrier layer adjacent the cathode, avoiding arcing and reducing the tendency for the cathode deposit to grow in a modular manner.
