Abstract: A composite envelope composed of a heat-shrinkable foil with a reinforcing layer containing tear-resistant fibers. The reinforcing layer is formed of a material which will melt below or at the temperature to which the heat-shrinkable foil is heated to stretch the foil and cause it to shrink back to its original condition so that the tear-resistant fibers are free to move in the melted material. Preferably, the composite is formed by providing carrier elements either having the fibers wrapped thereon or contained therein and assembling them with the shrinkable foil, heating to a stretching temperature to cause a melting of the carrier elements and stretching the foil at that temperature to create the memory and then holding the stretching forces until the foil has cooled to solidify the material of the carrier elements to form the reinforcing layer.

Abstract: The invention relates to a heat-shrinkable article that is at least partially coated with a temperature indicator. This temperature indicator is composed of an organic polymer having a suitable bonding agent, whereby the organic polymer is contained therein in a finely ground condition. As a result of this condition, the appearance of the agent is opaque and has a color corresponding to the degree of granulation and material constituent. When the melting point of the composition is reached, the material melts and becomes transparent or at least translucent. The color of the article shows through, so that this color change can be interpreted as a temperature indication.

Abstract: The invention is directed to a method for manufacturing heat-activatable articles from a synthetic thermoplastic material on which a shape memory is impressed by introducing molecular orientations and molecular structures. These articles, after the impressing of the shape memory, are subsequently subject to a further change in shape, at least in sub-regions thereof. The shape memory is influenced by this further change in shape.

Abstract: A longitudinally divided cable sleeve is composed of a flexible foil envelope having longitudinal closure elements along each longitudinal edge and has structural elements or support members for supporting the envelope as it is wrapped around a cable splice or region. Preferably, the flexible foil is composed of a plurality of layers including a plastic layer, a reinforcing layer and at least metal foil layer, which all adhere to one another by adhering layers.

Abstract: A heat-shrinkable, wrap around sleeve is formed of a cross-linked corrugated layer of polyolefin extending between two cross-linked layers of homogeneous plastic material with an elongation at least equal to that of the corrugated polyolefin layer. Preferably, the corrugations extend at an angle, which is preferably a right angle, to the longitudinal edges of the sleeve and in the direction of stretching of the sleeve prior to it being heat-shrunk onto the joint.

Abstract: A cable splice enclosure sleeve including a longitudinally slit substantially tubular sleeve made of a flexible material, preferably a multi-layer foil; reinforcing strips attached along edges of the slit, a locking strip engaging both edges of the slit in sealing relationship; and suspension devices attached along the locking strip to suspend the sleeve from an object such as a suspended cable.

Abstract: A heat-shrinkable sleeve consisting of at least one heat-shrinkable component and a mechanical reinforcing component secured thereto, characterized by the reinforcing component being permanently secured to the heat-shrinkable component after completion of the heat-shrinking process. The mechanical reinforcing component, preferably, consists of a carrier foil on which mechanical reinforcing elements are arranged and the reinforcing elements are preferably arranged to extend in two directions so that tearing of the sleeve is extremely limited.

Abstract: A heat-shrinkable sleeve which has a shrinkable component and comprises a cross-linked polymer in the form of an open grid, said shrinkable component being embedded into a non-shrinkable component. The individual elements forming the open grid create a plurality of grid cells and are undetachably connected to one another at the point of intersection of the elements.

Abstract: A wrap-around cable sleeve liner is formed from a blank consisting of a smooth covering sheet and a corrugated sheet, which are secured together and have a line of indentations extending at an angle to the corrugations of the corrugated sheet adjacent each end of the sheet to form a bend line for the adaptation portions. The cable sleeve liner blank is preferably cut from a large area panel and has the indentations formed after cutting the blank so that blanks for different sizes can be formed as needed.

Abstract: A shrinkable cable sleeve which is composed of a shrinkable envelope having a meltable inside layer and an inner cable insert. The inner cable insert is composed of a plurality of layers, wherein one layer is activatable by the application of heat, and the plurality of layers includes a basic foil layer and reinforcing elements which may be in a separate layer or embedded in the activatable layer. During assembly, a pressure tight cable sleeve will be produced by fusing the two activatable layers together.

Abstract: A terminal assembly or part for closing a conduit opening in a fitting, conduit socket or conduit includes a shrink tube having one end shrunk onto the conduit opening and the opposite end closed by an end part which may include a supporting element. In one embodiment, additional supporting elements are provided besides the supporting element of the end part. If an elongated object is to be inserted into the opening, at least a portion of the end part is removed to enable insertion of the elongated object such as a cable with the removal being accomplished without damaging any of the shrink tube so that a subsequent heat-shrinking of the tube onto the inserted elongated object will form a sealing closure with the object as the remains of the end part are expelled from the assembly.

Abstract: The invention involves a heat-shrinkable connection comprising a longitudinal channel and a cooperating element thickened at its end. The channel is composed of lateral leg parts which are dimensionally stable under the application of heat, and of at least one shrink region adaptable to the cooperating element in positively locking fashion under the application of heat. The shrink region in the connecting region thereby facilitates the joining of the connecting elements along the formed parts to be connected or along the longitudinal edges of an envelope.
