  • US Patent:
    4426413, Jan 17, 1984
  • Filed:
    May 7, 1982
  • Appl. No.:
    6/376073
  • Inventors:
    Vernon A. Fentress - Foster City CA
  • Assignee:
    Raychem Corporation - Menlo Park CA
  • International Classification:
    H02G 1306
    H01R 300
  • US Classification:
    428 36
  • Abstract:
    A heat-recoverable closure assembly for enclosing e. g. cable splices comprising a heat-recoverable outer sleeve surrounding a body to be enclosed thereby, a support member surrounding the body and within the sleeve which support member has slotted end portions arranged to be capable of forming a tapering transition from the support member to the body, and a flexible barrier layer bridging the slots of the slotted portions. The barrier may act to seal the slots against ingress of moisture ior heat, and the barrier layer preferably covers substantially all of one surface of the support. Foamed polymer layers are particularly suitable as heat barriers, and metallic layers carried on a flexible carrier are particularly suitable as moisture barriers. The barrier may be inside or outside the support member, to suit end use requirements. A heat barrier will normally be placed outside the support member when the latter is made of thermoplastic material.

  • US Patent:
    4498732, Feb 12, 1985
  • Filed:
    May 25, 1982
  • Appl. No.:
    6/381825
  • Inventors:
    Bruce D. Campbell - Portola Valley CA
    Vernon A. Fentress - Castro Valley CA
  • Assignee:
    Raychem Corporation - Menlo Park CA
  • International Classification:
    G02B 726
  • US Classification:
    350 9620
  • Abstract:
    A method and device for organizing a bight of an optical fiber and the like at a splice or slack point is provided. The method comprises wrapping the bight about a cylindrical core to form a helix or a pair of helices of opposite handedness, thereby both minimizing the diameter of a container necessary to enclose that bight and maximizing the bend radius of the fiber. The bight may be laid on a sheet for convenient wrapping, and a plurality of fibers per sheet, sheets per core, or cores per splice may be used if the number of fibers to be organized is large. A ready means of encapsulation is also provided.

  • US Patent:
    4478486, Oct 23, 1984
  • Filed:
    Aug 12, 1982
  • Appl. No.:
    6/407670
  • Inventors:
    Vernon A. Fentress - Castro Valley CA
    Francois Comet - Belmont CA
  • Assignee:
    Raychem Corporation - Menlo Park CA
  • International Classification:
    G02B 514
  • US Classification:
    350 9620
  • Abstract:
    A method and device for organizing the bight of an optical fiber and the like at a splice or slack point is provided. The method comprises laying the bight on a sheet in such a fashion that, when the sheet is wrapped about itself (and, generally, about a cylindrical core) in a spiral fashion, the radius of any bend in the fiber is greater than the minimum bending radius; and wrapping the sheet about itself (and the core). The method is suitable for both in-line and butt splices between fiber optic cables, and a ready means of encapsulation is also provided.

  • US Patent:
    4711517, Dec 8, 1987
  • Filed:
    Oct 25, 1985
  • Appl. No.:
    6/791437
  • Inventors:
    Vernon A. Fentress - Castro Valley CA
    Darryl A. Dawson - San Francisco CA
  • International Classification:
    G02B 636
    G02B 726
  • US Classification:
    350 9620
  • Abstract:
    A new and improved apparatus and method for use in installing fiber optic cable, which utilizes a novel connector-coupling nut assembly, is disclosed herein. The apparatus largely comprises an elongated connector body with means disposed about the body's circumference for receiving and retaining a coupling nut which has a similar internal configuration for mating with the elongated connector body. When received by the connector body, the novel coupling nut is held in a securely captive position along the elongated connector body by suitable retaining means configured about the exterior surface of the connector body and the interior surface of the coupling nut, which means interact with each other.
