Abstract: Curable fabric comprising first and second curing reactants, at least one of which is in the form of a fabric member, and comprising heat-recoverable fabric members.

Abstract: Pipe couplings are formed by consolidation of a polymer into braided fibre reinforcement by recovery of a heat-recoverable driver thereover. A liner, e.g. of non-cross-linked polyvinylidene fluoride, may be used, preferably with three layers of polymer/braid, to achieve a Freon-tight seal for coupling loosely swaged or butt-jointed refrigerator pipes. Braids carrying a consolidatable polymer which allows the braid crossover points to slip freely during recovery of the driver are preferred for optimum performance.

Abstract: A recoverable fabric for example a weave having a conductive metal warp and a recoverable polymeric weft may be provided with solder to provide an article for screening electrical components.

Abstract: A heat recoverable article comprises a recoverable fabric and a polymeric layer of at least 0.03 mm thickness, and preferably unstressed. Such an article can be recovered by means of a torch to provide an environmental seal around substrates such as cables and pipes.

Abstract: A recoverable article comprising a recoverable fabric having a recovery of at least 40% may be used for providing environmental protection.

Abstract: An article comprises two areas of heat-recoverable woven fabric which are joined together along a line by means of a mechanical joining arrangement, such as stitches, staples or a stitched or stapled zip, which penetrates the fabric. The direction of crimp of the area penetrated is substantially perpendicular to the line of the join, or the two areas have substantially parallel directions of crimp.

Abstract: A wrap-around device for enclosing at least part of an elongate substrate such as a pipe comprises a dimensionally-recoverable cover, preferably a dimensionally heat-recoverable cover, having an adhesive closure arrangement comprising two closure portions which can be brought into abutment to form an adhesive bond but which, when pulled in a direction away from each other after the adhesive bond has been formed, will change in configuration to form a lap joint.The device according to the invention enables an adhesive wrap-around device to be installed about a substrate in a simple manner without the possibility of misalignment of the closure portions.

Abstract: A device for enclosing at least part of an elongate object, for example a pipe line, comprises a dimensionally recoverable cover 21 one surface of which is partly or wholely coated with a closure adhesive 22 and covered by a layer of sealant.The cover is preferably in the form of a continuous sheet which may be cut to the appropriate length. The device may be wrapped around the object and the overlying sealant may then be peeled back or peeled away to expose the closure adhesive. The cover is bonded to itself or to the object to be enclosed by means of the exposed closure adhesive, and the device is then recovered by heating.

Abstract: The invention relates to a novel thermoplastic monoorganopolysiloxane resin comprising units of the formula RSiO.sub.1.5 and R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 wherein R,R.sub.1,R.sub.2 and R.sub.3 are hydrogen, or organic groups which may be the same or different, at least 85% of the R groups in the RSiO.sub.1.5 being organic groups, and at least two of the groups R.sub.1, R.sub.2 and R.sub.3 in each R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 unit being organic groups, and in which the ratio RSiO.sub.1.5 units to R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 units is from 1:0.005 to 1:0.03 on a molar basis. Such resins are useful as electrical insulation material and as hold out agents for heat recoverable materials.

Abstract: The invention relates to a novel process for the production of a thermoplastic, high softening point polysiloxane resin which comprises reacting a solvent-soluble partially condensed organosiloxane with a silane capping agent. The resins so produced are useful as electrical insulator material and also as hold out agents for heat recoverable articles.

Abstract: An Electrolytic cell having a separator positioned between a positive electrode and a negative electrode is disclosed in which the separator is a moulding of polymer material derived from a particulate polymer material having a polar graft-copolymerized surface. The separator may be deposited as a coherent film of the surface of an electrode by sintering the particulate material into a coating around the electrode using heat and/or pressure. Alternatively a shaped article such as a case, envelope, sheet film or the like may be prepared and used to wrap around or encase an electrode.
