Francis R. Sherliker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dispersions of siliceous solids in liquid organic media
    Patent number: 4374937
    Abstract: Dispersions of colloidal siliceous particles, preferably silica, may be prepared in organic liquids by means of a synergistic mixture of dispersing agents comprising a phosphorus oxy-acid derivatives and a long-chain amine. Dispersions containing a high weight fraction of siliceous solids are possible having a lower viscosity than is normally achieved.
    Type: Grant
    Filed: July 1, 1981
    Date of Patent: February 22, 1983
    Assignee: Imperial Chemical Industries Limited
    Inventors: Jozef Nemcek, Thomas A. Roberts, Francis R. Sherliker
  • Process for electrolytically preparing a semiconducting film on a flexible substrate
    Patent number: 4225408
    Abstract: Electrophoresis of a colloidal suspension of a semiconducting sulphide, sulphoselenide, selenide or telluride in an aqueous medium produces a thin pin-hole-free film on a surface of a substrate. The film may be employed in solar cells.
    Type: Grant
    Filed: April 18, 1979
    Date of Patent: September 30, 1980
    Assignee: Imperial Chemical Industries Limited
    Inventors: William A. Barlow, Maurice Rhodes, Francis R. Sherliker, Edward W. Williams
  • Electrocoating process for producing a semiconducting film
    Patent number: 4204933
    Abstract: Application of heat preferentially to one surface of a film of a semiconducting sulphide, sulphoselenide, selenide or telluride to establish a temperature differential between the surfaces of the film improves the electrical and photochemical properties of the film. The film may be employed in solar cells. Preferably the film is prepared by electrophoresis of a colloidal suspension of the semiconductor in an aqueous medium.
