  • Optical fiber dispenser
    Patent number: 4326657
    Abstract: A dispenser for feeding an optical glass fiber from a missile to provide a ommunication link from the missile to the ground; the dispenser includes a supply of optical fiber and a source of pressurized gas mounted in a housing having an orifice through which the optical fiber is fed and the gas exhausted during the feeding of the optical fiber from the missile.
    Type: Grant
    Filed: May 19, 1980
    Date of Patent: April 27, 1982
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: John B. Arpin, Sam Di Vita
  • Method of maintaining the strength of optical fibers
    Patent number: 4118211
    Abstract: The mechanical strength of an optical fiber is maintained by coating the er with an inorganic ceramic material that is impervious to both moisture and chemically corrosive environments. The ceramic coating is applied immediately after the fiber is drawn.
    Type: Grant
    Filed: June 22, 1977
    Date of Patent: October 3, 1978
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Thomas R. Au Coin, Sam Di Vita, Melvin J. Wade
  • Method of treating optical waveguide fibers
    Patent number: 4028080
    Abstract: Optical waveguide fibers are cleaned by a dry method involving irradiating the fibers in an oxygen-containing environment with shortwave ultraviolet light.
    Type: Grant
    Filed: June 23, 1976
    Date of Patent: June 7, 1977
    Assignee: The United States of America as represented by the Secretary of the Army
    Inventors: Sam Di Vita, John R. Vig
  • Method and apparatus for optical fiber transmission in a utility conduit containing a hostile fluid
    Patent number: H704
    Abstract: Optical fibers are used in a utility piping system containing oil, water or as by coating the fibers after drawing with an inorganic hermetic coating which is impervious to both moisture and whatever fluid is contained in the system. The hermetic coating permits the fibers to undergo the mechanical stresses encountered during insertion in the piping system without causing degradation of either the mechanical or optical performance of the fibers.
