Abstract: A reinforcement assembly to be impregnated with a plastic or rubber material for reinforcing an article, such as a pneumatic tire, the assembly having three layers of cords: a core layer, an intermediate layer and an outer layer. The intermediate layer and the outer layer have the same direction of winding and the same pitch. When the core layer is wound in the same direction as the intermediate layer, the pitches of these layers differ in such a manner that the ratio between the difference in the values of these two pitches and the larger value of these two pitches is at least equal to 0.30. In the intermediate layer the axis of each cord is arranged along a helix such that the ratio between the radius of curvature of said helix and the diameter of said cord is less than 75.

Abstract: A reinforcement assembly comprises from one to three layers of threads, one of which is a central layer having one or more shaped threads, i.e., threads having a center of gravity and a contour in an intersecting plane perpendicular to the longitudinal direction of the thread, the distance from any point on the contour to the center of gravity depending on the position of the point on the contour. The twist pitch of each shaped thread is different from the winding pitch of the shaped thread in the layer in which it is located and if the element comprises three layers, the winding pitch of the outer layer is different from the winding pitch of the subjacent layer. Reinforced articles include such assemblies impregnated with a material, in particular pneumatic tires.

Abstract: A novel construction of a trailing wire antenna radiating element using conductive material in the central core wound in a direction opposite to the conductive material on the outer layer in the skin effect area to reduce AC impedance. To compensate for the strength lost with the conductive material in the core area, high tensile strength and non-magnetic material such as stainless steel or beryllium copper is used in the outer layer. For a given diameter wire cable, the present device has much lower impedance and much higher strength while remaining more flexible.

Abstract: Small diameter wire rope having a relatively ductile and preferably solid core is found to be strong yet better resists shearing forces than similar rope having a high strength core strand.

Abstract: A wire rope is provided having a central core strand about which are wound outer strands. Non-linear spacer wires are present in the gaps between outer strands to assure the uniformity of such gaps and provide passageways from the interior to the exterior of the wire rope. A coating, usually of a suitable thermoplastic, is extruded into such rope to extend continuously from the core and between adjacent outer strands and through the passageways.

Abstract: A submarine power cable conductor consisting of at least one layer of stranded metal wires, all of said wires being laid in the same direction and at a periodically varied angle.

Abstract: Described is a novel marker for wire ropes, in the form of a polymer, e.g., polyester film carrying a highly abrasion-resistant impression. This polyester film is wound around a support element in spirally overlapping manner and is worked into a gap between the bundles of strands, at the same twisting angle as the latter.

Abstract: A rotation resistant rope comprising a central multi-wire strand of Seale's construction, an intermediate layer comprising a plurality of multi-wire strands closed in one operation around the central strand, and a covering layer of 10 multi-wire strands closed around the intermediate layer. Each intermediate and covering layer of strands has a direction of lay opposite to that of the other layer of strands. The outside strands and core are always laid opposite each other, but the wires within each of these strands may be Lang lay, although Regular lay is preferred, particularly for the outside strands. The 10 outside strands may comprise from 7 to 26 wires and all of the strands are identical. However, in a preferred construction each of the outside strands consists of 19 wires.

Abstract: The coaxial sub-marine telephone cable employs a central conductor which is formed by a compound twisted core of high tensile steel wires and of aluminum-based wires which are encased in a longitudinally welded copper tube that is applied tightly around the twisted core. The aluminum-based wire has high tensile strength, high breaking elongation and good electrical conductivity. The crushing of the aluminum based wires by the steel wires under the effect of radial pressures exerting on the core through sizing dyes while being manufactured is minimized and avoided by arranging the steel wires in contact with each other under radial compression so that they interact as an arch or vault.

Abstract: A metal cord having a core comprising one or more filaments for the reinforcement of rubber articles comprising a plurality of bundles of grouped filaments wherein the direction of lay of the filaments in the bundles is the same as the direction of lay of the bundles in the cord, each of the filaments having been subjected to plastic torsional deformation, and the average length of lay of each bundle in the cord being substantially equal to the average length of lay of each filament in the bundles, and wherein at any cross-section of the cord the filament or filaments which comprise the core of the cord differ along the length of the cord and belong to the same or different bundles.
