摘要： Extruded plastics (preferably heat-shrinkable) tubing having at least one internal dividing wall formed by heat-flowable (preferably hot-melt) adhesive material co-extruded with the tubing to provide at least two lumens extending longitudinally within the tubing. The adhesive preferably melts and flows under conditions used to heat-shrink the tubing.

摘要： A 15kv cable joint is enclosed within two half shells filled with sealant material (46). A Faraday Cage (28C) is disposed within the sealant material (46) around the jointed conductors. In order to maintain the Faraday Cage (28C) in position, an insulating support (150) is located in the sealant material (46) and fixed to the half shells.

摘要： A 15kv cable joint is enclosed within two half shells (38, 40) filled with sealant material (46). Displacement or thermal expansion of the sealant (46) is accommodated by various configurations of stress cones (34C) that have apertures (70) or surfaces that are flexible and arranged to maintain pressure on the sealant (46) for example during thermal cycling of the joint.

摘要： Replacing silicone paper release sheet of known adhesive-backed roll-feed 50 micron polyester curable marker product with 90+ (pref. 100) micron plastics release sheet (12) enables A4 sheets to be printed in sheet-fed printers with reduced curling or multi-sheet feeding and enables release sheet to be made from economically desirable non-stress-relieved plastics, whereas thinner plastics release sheets (and the polyester marker backing (10)) need stress relief to survive heat-curing of the printed material without unacceptable distortion. Preferred versions have spacing means (14), preferably a strip of adhesive tape, projecting from the surface of the release sheet (12) facing away from the printable marker (10) to facilitate separation of sheets from a stack thereof by maintaining air gaps between adjacent sheets in the stack.

摘要： Tubular layer of sealant (32) (preferably gel) on flexible (preferably tubular) carrier (30) provides advantageous sealing member, which can conveniently be compressed, e.g. in a tongue-and-groove joint (34, 36), to provide a sealed joint in items such as cable splice enclosures, car head lamp housings, gas meter casings, and domestic appliances. Styrene-alkylene or alkylmethacrylate-alkylene block copolymer gels coated (preferably co-extruded) on thermoplastic elastomer carriers are described. Gasket rings cut from such tubular articles, and provision of projecting fixing lugs for anchoring the articles to an object which is to carry them in use are also described.

摘要： Mica-wrapped wires for fire-resistant cables have an unusually low degree of overlap in the mica tape wraps, which unexpectably produces a smoother external profile while retaining an acceptable degree of fire protection. Two layers of glass-cloth-backed mica tape, preferably with a polymer film overlying the cloth, are preferably applied with their respective (low) overlaps staggered. This smoother wrapping is especially effective when thin (less than 0.8 mm) polymer coatings are to be extruded over the wrapped wire.
