  • Laser - optical fiber tuning and control system
    Patent number: 5463710
    Abstract: A laser-optical fiber tuning and control system which optimizes coupling of a laser output into an optical fiber by minimizing the amount of light scattered into the fiber cladding, which provides a realtime indication of whether the radiation reaches the output end of the fiber to an emergency shut-down switch, and which provides a communications system for control of the laser from the output end of the optical fiber.
    Type: Grant
    Filed: September 9, 1992
    Date of Patent: October 31, 1995
    Assignee: Hobart Laser Products, Inc.
    Inventors: David M. Filgas, Gordon M. McFadden, Jeffrey Broome, James F. York
  • High power laser - optical fiber connection system
    Patent number: 5291570
    Abstract: A system for coupling laser radiation at a high power to an optical fiber while dissipating heat from scattered laser and optical pump radiation, including an optical fiber, a protective ferrule surrounding a portion of the optical fiber extending from the input face of the optical fiber and welded to the fiber in the region of the input face and otherwise separated from the fiber by an air space, and a holder surrounding the ferrule to absorb scattered radiation and dissipate heat.

    Inventors: David M. Filgas, Gordon M. McFadden, Jeffery Broome, James F. York, R. Scott Wofford
  • Process for preparing bis(dialkylphenyl) pentaerythritol diphosphites
    Patent number: 4665211
    Abstract: An improved transesterification process for preparing bis-(2,4-dialkylphenyl) pentaerythritol phosphates using n-alkanes or cycloalkanes as solvents to provide high spiro/cage isomer ratios.
    Type: Grant
    Filed: December 3, 1985
    Date of Patent: May 12, 1987
    Assignee: Borg-Warner Chemicals, Inc.
    Inventors: Gary V. Marlin, James F. York
  • Polyolefins stabilized with cyclic diphosphites
    Patent number: 4305866
    Abstract: A process for the preparation of mixed aromatic-aliphatic phosphites. The process involves the reaction of an alkylphenol with diphenyl-(or a lower dialkyl-) pentaerythritol diphosphite. The process is simple and inexpensive, and produces a relatively pure product.
    Type: Grant
    Filed: August 30, 1979

  • Stabilizer for polymers
    Patent number: 4116926
    Abstract: An improved phosphite stabilizer for polymers, especially vinyl chloride polymers and olefin polymers. The phosphite is either a dialkylpentaerythritol diphosphite or a polyalkyl bisphenol-A polyphosphite; the improvement comprises the presence in such phosphite composition of a small proportion of triisopropanolamine.
