  • Tube furnace
    Patent number: 4748307
    Abstract: The evolution of particulate material from the inner surface of a tubular zirconia susceptor while fibre is drawn from preform is inhibited by providing that surface with a glassy finish by laser-beam fusion.
    Type: Grant
    Filed: May 1, 1986
    Date of Patent: May 31, 1988
    Assignee: STC PLC
    Inventor: John G. Lamb
  • Manufacturing optical fibre
    Patent number: 4608276
    Abstract: On line coating of optical fibre (20) adopts silicon nitride or oxynitride to provide an hermetic seal using chemical vapor deposition. Non-contacting gas seals (3,4) at the top and bottom of the reaction chamber are so constructed that fibre vibration is avoided, (6) surface flaws are minimized and the coating minimizes stress corrosion.
    Type: Grant

    Date of Patent: August 26, 1986
    Assignee: Standard Telephones and Cables Public Limited Company
    Inventors: John G. Lamb, Terence M. McHugh
  • Method of and apparatus for coating optical fiber with plastics material
    Patent number: 4455159
    Abstract: The rate at which glass optical fiber can satisfactorily be coated with a primary plastics coating by a liquid application method is enhanced by causing the fiber to enter the liquid contained in a coating vessel via a suction tube in which a partial vacuum is maintained by an air induction device. Optionally a funnel is used to deflect the exhaust away from the incoming uncoated fiber.
