Abstract:
This invention relates to a steel cord adapted for the reinforcement of rubber product. The steel cord (30) comprising a core strand (32) and three or more outer strands (34) twisted around said core strand (32). The outer strands (34) are multi- layer strands comprising multiple steel filaments arranged in an outer strand core (36) and at least one outer strand layer (38, 40), the steel filaments in the outer strands have a round or substantially round cross-section. At least one outer strand (34) comprises flattened portions (52) and non-flattened portions (54) along its length. The flattened portions create spacing S between adjacent outer strands (34) and gaps G between adjacent filaments in the outer strand (34), which improves rubber penetration and elongation of the steel cord (30), and finally improves the impact resistance of the steel cord (30). Besides, the flattened portions (52) limit the flare of the steel cord.

Abstract:
Die Erfindung betrifft ein Seil aus textilem Fasermaterial für Anwendungen, in denen Schrägzug auftreten kann, dadurch gekennzeichnet, dass das Seil ein Kern/Mantel-Seil ist, dessen Kern (1) und dessen Mantel im wesentlichen aus textilem Fasermaterial bestehen, dessen Kern (1) verseilt ist und welches zwischen Kern (1) und Mantel eine kraftschlüssige Umwindung mit einem Zugelement (2, 2', 2'') aufweist.
Abstract:
A steel cord (20, 30) has two ends and comprises steel filaments (32). At least some of the steel filaments (32) are twisted along the length of the steel cord (20, 30) - except for a local region (26, I) at at least one of the two ends - with a cord lay length L c . The steel cord (20, 30) is additionally cold twisted in said local region (26, I) so that locally the at least some of the steel filaments (32) have a lay length that is less than 60% of the cord lay length L c in order to avoid flare / fraying and to facilitate further processing. A corresponding method is disclosed, too.
Abstract:
A method of manufacturing an assembled conductor (202) includes: arranging (S2) a plurality of peripheral wires (110) having anisotropic cross-sectional shapes around a central wire (130); bundling the central wire and the peripheral wires that have been arranged, to form a conducting wire bundle (200); and rolling the conducting wire bundle to form the assembled conductor (202). The arranging (S2) includes a bending process (S21, S22, S23) for bending the plurality of peripheral wires in directions along imaginary lines that extend radially relative to an axis of the central wire on an imaginary plane intersecting the axis of the central wire.
Abstract:
Various subsystems for a submerged or waterborne system used to generate power derived from fast-moving water currents using an induction-type generator system equipped with one or more fin-ring propellers are disclosed. Many of the systems and subsystems shown and described herein are individually suitable for use in systems using conventional generator drive systems and other means of power creation. Means for transmission of power generated by such systems, tethering and mooring systems, and methods for improving system transportation, installation and maintenance are also disclosed.
Abstract:
There is disclosed a method of forming an eye end termination on a rope having a core comprising a plurality of multi-strand subropes, and a rope having a core comprising a plurality of multi-strand subropes and at least one eye end termination. In one embodiment, a method of forming an eye end termination (16) on a rope (10) having a core (12) is disclosed. The rope comprises a plurality of multi-strand subropes (14) each of a first strength, and the method comprising the steps of: coupling a pair of subropes ( 14) in the rope core ( 12) together using a multi-strand coupling rope ( 18) of a second strength which is greater than said first strength, to thereby form at least part of the eye end termination (16). The step of coupling the pair of subropes (14) together comprises splicing a first portion of a coupling rope (18) to one of the subropes in the pair of subropes, and splicing a second portion of the coupling rope to the other one of the subropes in the pair of subropes.
