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.

Abstract: A sealing member is provided which can be spirally wrapped around an elongate article (e.g., a cable) comprises a strip of sealing material (e.g., gel sealing material), and at least one series of gripping elements situated adjacent to the strip of sealing material and extending beside a longitudinal edge of the sealing material. In use, the gripping elements cause the sealing member to grip an elongate article around which it is spirally wrapped. The sealing member may also include a support strip to which the strip of sealing material and each series of gripping elements are attached.

Abstract: The present description pertains to a duct seal, or splice case seal, or other sealing member which is an inflatable envelope having an opening directly through a wall of the envelope or between walls thereof through which a probe is inserted to introduce a pressurizing medium. A means is provided for sealing of the sealing member upon withdrawal of the probe. Preferably the pressurizing medium is air. Preferably the walls of the envelope are substantially non-stretchable. An internal flap may be provided across the opening through which the probe is inserted, where the internal flap seals in response to pressure from within the sealing member. The flap preferably comprises a flexible polymeric sheet fixed to a wall of the sealing member such that the probe can pass through the hole and displace the flap, with the probe preferably passing between the flap and the wall substantially in the plane of the wall and at an angle of less than about 45.degree. to the plane of the wall.

Abstract: A flexible hollow sealing member that can be inflated to seal a gap between first and second articles and that has: a hole directly through a wall or between walls thereof through which hole a probe can be inserted to introduce pressurizing medium into the member, and by which the hole is automatically sealed on withdrawal of the probe.

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.

Abstract: An environmentally sealed cable splice includes (a) a butt cable splice between at least two substantially side-by-side cables, (b) an enclosure sealed around said cables, the enclosure including (i) a first part through which the cable extends, and (ii) a second part which is hollow and together with the first part forms a closed space, the first and second parts having internal and external cross-sections such that one can be slid upon the other so as to give an overlap between the first and second parts, and (c) an inflated sealing member carrying sealing material, the sealing member being within the enclosure and in contact with the cables and the overlap.

Abstract: A device capable of co-operating with an outer pressure member to form a sealing block between two or more elongate substrates and a hollow housing within which the substrates extend, the device comprisingi) an elongate support member andii) two or more elongate flexible leaves each of which comprises a sealing material that (a) is not heat fusible, (b) is secured relative to the support member, and (c) extends laterally of the elongate support member,the device being positioned, in use, between the elongate substrates, so that a first of the flexible leaves extends at least part of the way around the periphery of a first of the elongate substrates, and a second of the flexible leaves extends at least part of the way around the periphery of a second of the elongate substrates, so that in co-operation with the action of the outer pressure member acting inwardly on the substrates and the device, and outwardly onto the housing, a sealing block is made between the elongate substrates and the housing.

Abstract: A kit of parts for closing an end of a duct having a polygonal internal cross-section comprises: (a) a sealing member that can be inserted into the duct to form a seal therewith; and (b) a device that can be inserted into the duct to provide sealing material therein, comprising a support and sealing material located on the support. The device is shaped such that at least some of the sealing material of the device is located at the corners of a polygon, to form a seal, in use, between the sealing member and an internal surface of the duct at each corner of the polygonal internal cross-section thereof.

Abstract: A flexible hollow sealing member that can be inflated through a hole in a wall thereof to seal to a first article, the member having: a first sealing material at an inwardly-facing surface of the wall, which first sealing material can be deformed to block the hole by pressure within the member when inflated; and a device for maintaining, during deformation of the first sealing material, separation between the article and an outwardly-facing surface of the wall immediately adjacent the hole.

Abstract: A method of sealing a duct having a non-uniform cross-section which comprises:(i) positioning within the duct a device for locating a sealing material at a localized portion of an inner surface of the duct, at the non-uniformity; and(ii) positioning within the duct a sealing member than can at least partially block a cross-section of the duct such that the sealing material forms a seal between a portion of the duct and a portion of the sealing member.

Abstract: A method of enclosing a substrate within a heat-shrinkable sleeve, which comprises the steps of:a) attaching to the substrate a slideway;b) attaching to the slideway a clip having at least two legs;c) positioning a heat-shrinkable sleeve around the substrate;d) sliding the clip by means of the slideway and with respect to the substrate such that at least one portion of the sleeve becomes positioned between the legs of the clip, ande) causing heat-shrinkage of the sleeve.

Abstract: An assembly capable of sealing an elongate substrate that is curved or angled along its length, which has a heat-shrinkable wraparound sleeve (1) having closure rails (3) adjacent opposing longitudinal edges thereof which can be held together by positioning a closure member thereover to maintain the sleeve in the wrapped-around configuration during heat-shrinkage and the closure member, which comprises an elongate channel (7) of sheet material substantially C-shaped in transverse cross-section having transverse first and second slits (9, 10) therein that extend substantially entirely across its width, respective first and second slits extending through each longitudinal edge, and giving the channel flexibility in two mutually perpendicular planes.
