  • Wire connect and disconnect indicator
    Patent number: 4911655
    Abstract: The invention provides for an electrical connection device wherein the portion of the device making the electrical contact is part of but spaced from the point of mechanical retention of the wire to which an electrical contact is made. The invention also provides for an electrical connection/wire insulation disconnect indicator to enable the installer to know when an electrical contact is formed or an insulated wire can be withdrawn from the apparatus without stripping the electrical insulation therefrom.

  • Wraparound fabric article and method of making the same
    Patent number: 4900596
    Abstract: A method of making wraparound fabric article comprises positioning a closure member(s) at an edge portion of a sheet of fabric (1), and welding or bonding (a) fibres of the fabric adjacent to the closure member so as to trap the closure member by preventing of reducing relative movement of fibres at the edge portion (2). Preferably, the method involves attaching two closure members to the fabric, by which the article can be held in a wrapped around configuration.

  • Splice case
    Patent number: 4885432
    Abstract: A splice case for telecommunications cables is provided which is completely wraparound. Two rigid half shells (6) surround a wraparound impermeable sheet (4) to cover the central part of the splice. The impermeable sheet (4) provides sealing, and the half-shells (6) mechanical restraint. Wraparound end parts (12) are also provided and a sealing material (10) seals the impermeable sheet (4) to the half shells (6) and/or end-parts (12), so that the seal thus formed in not put into peel when the splice is pressurized.

  • Re-enterable closure assembly
    Patent number: 4885194
    Abstract: A re-enterable closure assembly for enclosing an elongate substrate such as a telephone or power cable, has an outer sleeve, preferably heat recoverable, and an inner liner to protect the cable against heat and mechanical damage. The liner has two major parts, a support and a disposable layer, thus allowing the outer sleeve to be removed, for repair etc, without damaging the liner. This could not easily be acheived in a one piece liner since a bond generally must be formed between the liner and the outer sleeve to prevent wicking of moisture vapour.

  • Heat-recoverable article
    Patent number: 4879799
    Abstract: An article comprising a heat-recoverable conduit is provided with a plug or cap within or around said conduit to prevent the ingress of contaminants. The plug or cap comprises two principal parts; the first part, which is hollow, sits inside or around the conduit and the second part, which is attached to or in engagement with the first part, blocks the conduit. The second part can be detached or disengaged before recovery so that, for example, a supply line can be passed through the conduit and the first part can then be removed, destroyed or deformed prior to or during recovery. The plug or cap may also act to prevent premature recovery of the conduit.

  • Closure for wraparound sleeve
    Patent number: 4860799
    Abstract: A wraparound sleeve has closure members, typically in the form of upstanding rails, at its longitudinal edges. A channel having a discontinuity along its length is positioned over the closure members to hold the sleeve in a closed configuration. A clip is positioned between the closure members and the channel to bridge the discontinuity in the channel.The discontinuity in the channel preferably extends through the channel entirely, so that the channel is in two or more parts, which can be installed end to end.The discontinuity in the channel aids installation, particularly where the closure to be formed is of long length.This application is a continuation of application Ser. No. 920,493, filed Oct. 17, 1986, now abandoned, which is a continuation of application Ser. No. 071,536, filed July 9, 1987, now abandoned.

  • Optical fiber jaw connector
    Patent number: 4848870
    Abstract: An optical fiber connector includes fiber end aligning jaws which have pyramid shaped entrances which are keyed to pyramid shaped collets for keeping the jaws in an expanding attitude to allow for easy fiber insertion into the jaws. Subsequent to fiber insertion, a fiber contact is locked to the connector so as to simultaneously release its corresponding collet an amount sufficient so that the jaws are urged into aligning contact with the fiber.
