  • Patent number: 6152767
    Abstract: A cable closure is provided with at least two housing parts which, in use, are brought together, and when brought together provide a cavity for containing sealing material, through which one or more cables may extend into the closure. The cable closure also includes a sealing material which is contained in the cavity upon bringing the housing parts together, and, which seals between the cable (s) and the housing part(s); and at least one resilient member which, in use, is contained in the cavity. When the housing parts are brought together, in use, the resilient member is compressed, and thus causes the resilient member, by its resilience, to apply a compressive force to the sealing material.

  • Patent number: 6150608
    Abstract: A seal for sealing an aperture in an object, through which aperture one or more elongate article(s) extend(s). The seal includes at least two pressure members; at least two seal members to seal the aperture, at least part of at least one of which is situated, in use, between the at least two pressure members; and a compression device to compress the seal members in use by moving the pressure members closer together. The seal is arranged such that each elongate article extends in between at least two seal members, the seal members being situated adjacent to each other in a lateral direction with respect to the direction in which the elongate article(s) extend(s), and being arranged to form a sealing contact with each other and with each elongate article when they are compressed by the compression device.

  • Patent number: 6107571
    Abstract: A seal for sealing between a cable and a casing enclosing part of the cable includes a wall member having a plurality of substantially concentric removable portions which may selectively removed to provide a cable aperture of required diameter through the wall member. The seal also includes sealing material retained by the wall member, which seals, in use, around a cable extending through the cable aperture in the wall member. When a removable portion of the wall member is removed, a corresponding portion of the sealing material is also removed, thereby providing a cable aperture of the required diameter through the sealing material.

  • Patent number: 5952071
    Abstract: Two-component curable adhesive for blocking automotive wiring bundles, the respective components preferably amine-terminated polyamide Part A, and acrylate, anhydride or epoxy Part B, being contained in separate sheets which are inter-leaved with one another. The concentration of the reactive components in the sheets is chosen to cause the adhesive to flow on initial heating and then to cure to resist further flow at elevated temperatures in service. Apparatus, kits and method for blocking cables or wire bundles using the adhesive are also claimed.

  • Patent number: 5948218
    Abstract: An elongate electrode, usually an anode, is provided, suitable for use in an impressed current corrosion protection system. The electrode comprises a central elongate core, usually a metal such as copper, an optional conductive polymeric composition surrounding the metal core and having a higher electrical resistivity than the core, but being in electrical contact with the core, a flexible jacket, for example, a fabric braid containing within it particulate coke, and tensioning wraps positioned around the flexible jacket. The purpose of the tensioning wraps is to compact the coke particles relative to their compaction in the absence of the tensioning wraps.

  • Patent number: 5922990
    Abstract: A device for forming a seal around an elongate member, such as a wire, is provided. A device includes a first housing part and a second housing part movably connected to the first part. Sealing material such as a gel is positioned in the first housing part and provides a surface onto which the elongate member may be placed. A first member is positioned in the second housing part so as to displace the elongate member substantially laterally into the sealing material on movement of the second housing part relative to the first housing part. A device for applying a force to the sealing material on relative movement of the housing parts is also provided.

  • Patent number: 5883333
    Abstract: A cable splice closure is disclosed, which includes a casing which, in use, is closed around a cable splice; and at least one cable gripper comprising a strip which, in use, is wound around at least one cable extending into the casing. Closing the casing, in use, automatically causes the or each strip to tighten around the or each cable around which it is wound, thereby gripping the cable. The cable gripper strip may have the ability to decrease in length when wound and compressed around a cable, thereby allowing it to contract, and therefore tighten, around the cable.
