  • Method and apparatus for installing anodes at underwater locations on offshore platforms
    Patent number: 4484838
    Abstract: Method and apparatus whereby an anode may be mounted on a subsea propulsion vehicle, transported to a selected portion of a platform substructure and then remotely and operatively connected to the substructure, as by explosively-actuated bolts.
    Type: Grant
    Filed: April 9, 1982
    Date of Patent: November 27, 1984
    Assignee: Shell Oil Company
    Inventor: James W. Stevens
  • Method of forming articles by plating
    Patent number: 4409070
    Abstract: A method of forming an article having a rough surface for being adhesively bonded to a further member includes pressing a discontinuously surfaced layer 12 of electrically conducting material (for example copper powder) onto the surface of an electrically conducting substrate 11 (for example uncured synthetic rubber loaded with carbon black), so that portions of the layer 12 are embedded in the surface. The exposed parts of the layer 12 are then electro-plated with a metal and the substrate is then removed to provide said formed article.

  • Mechanical damage resistant members and electro-plating rubber or rubber-like material
    Patent number: 4314892
    Abstract: A mechanical damage resistant member, e.g. a leading edge sheath for a propeller blade, comprises a substrate made of electrically conductive rubber or rubber-like material which has had an electrically conductive material layer, e.g. a layer of metal powder, pressed into its surface while the rubber is cured, the substrate then being electro-plated over the conductive layer. This method of electro-plating rubber and rubber-like material has general application, i.e. not just in relation to the described damage resistant member.
