Cable Rubberized In Situ Comprising A Rubberizing Composition Comprising A Corrosion Inhibitor
A cord rubberized in situ (C) comprising: an internal layer of the cord (CT1), an external layer of the cord (CT3), a rubber composition (20) positioned between the internal layer of the cord and the external layer of the cord. The rubber composition (20) comprises a compound of formula (I):
##STR00001##
in which X and Y represent, independently of each other, an alkali metal or alkaline earth metal cation.
Cable Gummed In Situ And Containing A Gumming Composition That Contains A Corrosion Inhibitor
A cord rubberized in situ (C). Internal layer of the cord (CT1) comprises N1 internal thread(s). External layer of the cord (CT3) comprises N3 external threads wound helically around the internal layer of the cord. Rubber composition (20) is positioned between the internal layer of the cord and the external layer of the cord, and comprises a compound of formula (I) or a salt of this compound:
##STR00001##
in which: each R1, R2 and R3 group represents, independently of one another, an alkylene, arylene, arylalkylene, alkylarylene or cycloalkylene group, each X.sub.1 and X.sub.2 group represents, independently of each other, COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) with R and R representing, independently of each other, hydrogen or an alkyl group, and X.sub.3 comprises at least one COOH, CONHOH, SOOH, PO(OR)(R) or PO(OR)(OR) group with R and R representing, independently of each other, hydrogen or an alkyl group.
Two-layered metal cord rubberized in situ by an unsaturated thermoplastic elastomer
A metal cord has an M+N construction with two concentric layers. An internal first layer or core includes M wire(s) of diameter d.sub.1, M having a value from 1 to 4. An external second layer includes N wires of diameter d.sub.2 and is positioned around the core, the N wires being wound in a helix. Between the wires of the two layers are gaps, some or all of which include a filling rubber based on an unsaturated thermoplastic elastomer. The filling rubber may be, for example, based on an SBS or an SIS block copolymer. When used in a molten state, the thermoplastic elastomer presents no problem due to unwanted stickiness if the filling rubber overspills outside the cord after manufacture. The unsaturated and therefore (co)vulcanizable nature of the thermoplastic elastomer makes it compatible with diene rubber matrices used as calendering rubber in metal fabrics intended for reinforcing tires.
Method of manufacturing a two-layer metal cord rubberized in situ using an unsaturated thermoplastic elastomer
A method of manufacturing a metal cord with two concentric layers of wires is provided. The cord includes an internal layer of M wires, M having a value from 1 to 4, and an external layer of N wires. The cord is rubberized from within in situ. That is, during manufacture of the cord, the cord is rubberized from inside. According to the method, the internal layer is sheathed with rubber or a rubber compound by passing the internal layer through an extrusion head, and the N wires of the external layer are assembled around the sheathed internal layer to form a two-layer cord rubberized from the inside. The rubber is an unsaturated thermoplastic elastomer that is extruded in a molten state, and preferably is a thermoplastic styrene (TPS) type of thermoplastic elastomer, such as an SBS or an SIS block copolymer, for example.
Method and apparatus for curing of pre impregnated synthetic components in situ
A cable, which may be produced by the method described herein, comprises a cable with a core jacket comprising a predetermined cable length where the core jacket comprises a thermoplastic material comprising a memory characteristic which changes based on temperature, a set of core components, disposed within the core jacket, which comprise the predetermined length, and a strength member disposed within the core jacket intermediate the core components and the core jacket. The strength member comprises a selectively activated pre-impregnated uncured synthetic material adapted to be cured while in production, the strength member comprising a length substantially equal to the predetermined length.
Hybrid compensation member
A compensation and tie-down member for an elevator system includes one or more lightweight compensation tension elements having a first tensile strength/unit mass/unit length, and one or more heavier weight compensation tension elements having a second tensile strength/unit mass/unit length less than the first tensile strength/unit mass/unit length.
Elongate body with exoskeleton
An elongate body adapted to bend in a single plane, comprises a rope extending within a succession of individual tubular elements closely spaced along the rope. Each element has on two opposite sides of the plane an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in said plane. The tubular elements thus form an exoskeleton around the rope which must be breached before the rope can be cut. The geometry of the tubular elements can be such that notwithstanding gaps, the rope cannot be readily accessed unless the exoskeleton is broken.
