    Abstract: Provided are a rubber article reinforcing steel wire that is superior in bending fatigue properties to the related art and has a flat cross-sectional shape, and a rubber article using the wire. In a rubber article reinforcing steel wire 10, a major diameter and a minor diameter are substantially perpendicular to each other. Assuming that the major diameter is W, the minor diameter is T, a straight line that passes through a center of the major diameter in a width direction and is parallel to a minor diameter direction is L1, a straight line that passes through a center of the minor diameter in a width direction and is parallel to a major diameter direction is L2, an intersection point of the L1 and the L2 is a center point C, a region within a half of a distance from the center point C to a surface is a central region Rc, and a region outside the central region Rc is a surface layer region Rs, a Vickers hardness Hvc of the central region Rc is more than a Vickers hardness Hvs of the surface layer region Rs; and assuming that a Vickers hardness on the L1 in the surface layer region Rs is Hv1, and a Vickers hardness on the L2 in the surface layer region Rs is Hv2, relationships represented by Hvc−Hv1≦150, Hvc−Hv2≦150, Hv1/Hvc×100≧85.11, and Hv2/Hvc×100≧79.84 are satisfied.

    Abstract: The present invention pertains to a UHMWPE film having a tensile strength of at least 2.0 GPa, a tensile energy to break of at least 30 J/g, an Mw of at least 500 000 gram/mole, and a Mw/Mn ratio of at most 6. The film may be manufactured via a process which comprises subjecting a starting UHMWPE with a weight average molecular weight of at least 500 000 gram/mole, an elastic shear modulus determined directly after melting at 160° C. of at most 0.9 MPa, and a Mw/Mn ratio of at most 6 to a compacting step and a stretching step under such conditions that at no point during the processing of the polymer its temperature is raised to a value above its melting point. The film may be used as starting material in any applications where high tensile strength and high energy to break are important. Suitable applications include ballistic applications, ropes, cables, nets, fabrics, and protective applications.

    Abstract: A rope including polyethylene elongate elements oriented in the length direction of the rope, where for at least part of the elongate elements the distance of the element to a central longitudinal rope axis varies over the length of the rope. The polyethylene elongate elements including tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt. %. The distance of at least part of the elements to the central longitudinal rope axis varies over the length of the rope between a longitudinal line which is at most 30% from the outside of the rope and a longitudinal line which is at most 30% from the central longitudinal axis of the rope. Such a rope shows a high strength-strength ratio (the ratio between the strength under use conditions and the fresh strength of the rope).

    Abstract: An elastic link for adjusting the distance between two members, at least one of which is mobile, is characterised in that it includes at least two elastic yarns each attached through one of the opposite ends thereof to two points distant from each other of an intermediate portion of a strap located between the extreme portions of the latter, under conditions such that when a tensile force is applied on said strap, the first elastic yarn is stretched first, the second elastic yarn being then stretched based on the magnitude of the applied tensile force.
