In a paste type lubrication between a steel wire rope and a rope groove of a pulley, is applied a paste lubricant which contains oil and small solid particles. Solid particles could be of a wide variety sizes and they are small enough to at least partly fit into the valleys between the peaks of surface roughness of the ropes or the rope groove.

A structural cable of a construction work. The structural cable including a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, a housing located within the sheath and fixed relative to the sheath, said housing defining a cavity, the bundle of tendons being at a distance from the housing and the cavity, the bundle of tendons being located outside the housing and the cavity, said cavity extending longitudinally relative to the sheath.

A manipulation rope having an excellent torque transmittability is provided. A manipulation rope 2 is a rope 2 that is advantageously used as a manipulation rope for a medical instrument, and includes a side wire 6 or a side strand which is an outermost layer, the side wire 6 or the side strand having a spiral shape in which a flatness that is an aspect ratio obtained by a major axis being divided by a minor axis is greater than 1.00 and not greater than 1.10. An elongation of the rope at a time when a tensile load that is 1.0% of a breaking load is applied, is preferably not less than 0.04% and preferably not greater than 0.10%.

Described herein are devices and methods for guide elements configured with variable stiffness, with one or more flexible portions and one or more stiff portions. The flexible portion is be used as a tensioning element of a cinchable implant to tighten or compress tissues while the stiff portion is used to facilitate the insertion or withdrawal of portions of the implant or instruments acting on the implant. The guide element is further configured to be separated or severed between the flexible and stiff portions so that a flexible portion is left within the body as part of the implant, while the stiff portion is withdrawn from the body after implantation is completed.

A pre-stressed concrete structure comprises a steel wire or a steel strand. The steel wire or steel strand has been pre-tensioned before curing of the concrete or grout. The steel wire or steel strand is provided with a zinc coating. The zinc coating has a weight ranging between 70 g/m.sup.2 and 950 g/m.sup.2. The steel wire or steel strand has an outer surface that is provided with indentions to provide mechanical anchorage points in the concrete structure. The steel wire or steel strand is further provided with a passivation layer in the form of a metal oxide layer.

A bicycle control cable is provided with a central wire and at least one resin string. The at least one string made of resin is spirally wound onto the radially outermost surface in a direction intersecting with a center longitudinal axis of the central wire with a pitch less than or equal to 1 millimeter. The at least one resin string defines a spiral gap between adjacent windings of the at least one resin string. The at least one resin string defines an outer sliding surface for reducing a sliding resistance of the central wire. The central wire and the at least one resin string define an inner wire configured to slidably move in an axial direction with respect to the center longitudinal axis of the central wire within an outer case to operate a bicycle component.

A string, rope, or strap with repetitively spaced openings/flexible eyelets from bifurcated braiding or weaving, or from cutting and sealing. The bifurcated openings are preferably created from a single rope or strap that is subsequently braided or weaved into two strings, ropes, or straps and then back into one. The frequent and periodic placement of these eyelets on the string, rope, or strap, allows the user to easily tie down items. The rope or strap is flexible enough to pull it in on its self, through its eyelets. The ends of the string, rope, or strap are finished into a hard tip.

A lift unit for supporting a subject includes a lift body configured to travel along an overhead rail and a lift strap having a payout length extending from the lift body. The payout length retracts and extends relative to the lift body. The lift strap includes a woven fiber construction having a pattern integrated into the woven fiber construction. The pattern includes a plurality of markings indicative of the payout length.

A tungsten wire according one aspect of the present disclosure includes: a metal wire containing one of tungsten and a tungsten alloy; and a plating layer which covers a surface of the metal wire. The plating layer contains copper.

A method of manufacturing a dog toy, the dog toy including a rope, at least a segment of which is non-linear and a thermoplastic rubber coating surrounding some but not all of the rope. The dog toy is characterized as having exposed rope and rope covered by the thermoplastic rubber along its length such that a dog using the dog toy has access to the rope for chewing but the rope is resistant to degradation due to the thermoplastic rubber coating. The method includes bending the rope for a sufficient period of time such that the rope maintains its non-linear configuration, thereupon the rope is applied together with a pre-molded thermoplastic round core to a mold and the thermoplastic rubber is bonded to the rope to create the shape of the toy and to surround some, but not all of the rope with the thermoplastic rubber coating.
