The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

Provided are a CNT forest having favorable spinning properties, and as a method for producing such a CNT forest, a production method in which CNT forest 45 is formed by applying, as deposition base surface 44, a surface including at least one part of inner surface 43 in opening substrate 40 having interior space 42 communicating with an outside through open portion 41, and CNT forest 45 has spinnable portion 47 at end 46 on a side of open portion 41.

The present invention discloses a fiber surface treatment composition, characterized in that the composition is comprised of a silane coupling agent, a polymer and a water repellent agent, wherein the polymer is a copolymer of a polyurethane/acrylic acid polymer, wherein the acrylic polymer is selected from the group consisting of polyacrylic acid, polyacrylates or acrylic acid-acrylic acid ester copolymers. The invention also discloses an insulating fiber having the composition on its surface, the preparation method for it, and an insulating yarn and an insulated cord. The insulated fibers, yarns and ropes of the invention have the advantages of moisture resistance, washing resistance, ultraviolet aging resistance and the like. Particularly, the insulated ropes can be applied to the charging work of transmission lines, especially the UHV transmission lines.

The proposed sheath is for a structural cable (10) having a path between an upper anchorage (16) and a lower anchorage (17). It comprises sheath segments (21) assembled along the path of the structural cable, at least one supporting rope (30) extending along the sheath segments and having an upper end connected to the construction work adjacent to the upper anchorage, and connectors (32) for connecting the sheath segments to the at least one supporting rope. The connectors (32) are configured to block relative upward movement of the supporting rope (30) with respect to the sheath segments (21) and to allow relative downward movement of the supporting rope with respect to the sheath segments.

A rope is described including a first terminus, a first end, and a bulk portion. The first end portion consists of a predetermined length of the rope from the first terminus, and the bulk portion is connected to the first end portion. At least one of an external coloring and an external patterning of the first end portion is different from that of the bulk portion. The marked end of the rope allows a climber or other user to easily recognize that he or she is nearing the end of the rope.

Aspects of the disclosure relate to a pulling device for pulling wire, cable, and/or duct products through an opening (e.g., bore, conduit, duct, etc.). The pulling device includes a gripping sleeve having a first end and a second end, the first end of the gripping sleeve configured to receive the product. The second end of the gripping sleeve is coupled with an eye, the eye configured to guide the pulling device through the opening. The pulling device further includes a cord configured to remove a protective material that can at least partially enclose the gripping sleeve and/or the product. The cord can be coupled to at least one of the gripping sleeve or the eye, and extend distally beyond the first end of the gripping sleeve.

A wire rope having improved durability and that can be used in a medical device to be inserted into a patient's body. The wire rope includes a core wire and side wires. The core wire is a special metal element wire that has a hardness at an outer periphery in a cross-section thereof that is higher than that at a center in the cross-section thereof. The wire rope does not include grease.

A yarn in which slipping of filler materials from a tubular member can be reduced while suppressing the manufacturing cost is provided. The yarn has a tubular member, and a plurality of filler materials that are formed into a strip-like shape, and is configured by loading the filler materials into the tubular member in a state where the longitudinal directions of the filler materials are made extending along the axial direction of the tubular member. In the yarn, the tubular member is configured by using wire material that is knitted so as to produce stitches. The wire material has arcuate loop portions that define parts of external shapes of the stitches. In a state where the tubular member is developed, the loop portions are expanded in a direction that is inclined with respect to a straight line that extends in the axial direction of the tubular member.

A tow cable for a decoy on a fast jet aircraft is described. The tow cable has a composite structure with a high friction fibre outer containment braiding, and low friction fibre internal strength members. Additional to these internal fibres may be electrical conductors and optical fibres. The whole composite providing a tow cable with high towing endurance and reliable in-flight performance, for flight profiles including high performance manoeuvres and in-flight refuelling.

A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt, each tension member including a plurality of load carrying fibers, the plurality of load carrying fibers including a plurality of aromatic polyester based fibers. A jacket material at least partially encapsulates the plurality of tension members.
