Abstract:
A mooring member comprises a rope (1) configured for extending between a vessel (9) floating in a body of water (W) and an anchoring device (10). The mooring member comprises a plurality of functional elements (4), wherein a first functional element (4) is wound onto at least a portion of the rope (1), a second functional element (42) is wound onto the first functional element (4), and so on, until the outermost functional element (4) is wound onto the second-to-outermost functional element (44). The functional elements are wound in a helical configuration, and comprise one or more of the means in the group comprising: damage protection means, buoyancy means, optical detection means, sonar detection means, stiffness control means, anti-fouling means.
Abstract:
A line (1A) to form a fly line to tippet connector comprises three tubular braids (2, 3 and 4) co-axial with each other, the innermost braid (2) terminating short of an end (5) of the intermediate braid (3), and that end (5) of the braid (3) terminating short of an end (5) of the outermost braid (4), so providing a tapered line with the ends (5) of the braids (2) and (3) at the reductions (8 and 7) being hidden and protected against unravelling.
Abstract:
A reinforcement rope to be used in production of prestressed reinforced concrete constructions has a variable diameter (D1 and D2) along its length and its sections (2) of large diameter (D2) alternate periodically with the sections (3) of the small diameter (D1), smoothly blending one with the other. The proposed rope is produced either by use of a core with periodically changing diameter or by use, for the outside layers, of a wire with periodically changing diameter.
Abstract:
The invention concerns an elongate, flexible line (16) for providing a linkage between a first structure (10) and a second structure (14). The line may be a mooring line. It has an elongate tubular sheath (18) of braided material, the sheath being able to change reversibly and repeatedly in length and its braided structure being such that an increase in length of the sheath is accompanied by a decrease in its lateral dimension. Within the sheath is an impervious flexible bladder (28). The bladder defines a fluid-containing internal chamber (36) which is acted on by the sheath so that the volume of the chamber varies with the length of the sheath. A pressure source (42) is arranged to pressurise the chamber. A passage (40) communicates with the chamber and incorporates a restriction (44). In operation the pressurised bladder urges the sheath to expand laterally and so to contract in length. An increase in extension of the sheath causes fluid to be exhausted from the chamber through the restriction, increasing chamber pressure and providing a damping force opposed to the sheath's extension.
Abstract:
A tapered rope structure (20) comprises a first rope region (24), a second rope region (26), and a splice region (22). The splice region (22) is between the first and the second rope regions (24, 26) and comprises a taper portion (32), a finish portion (34), and an overlap portion (30). The finish portion (34) is arranged between the taper portion (32) and the first rope region (24). The overlap portion (30) is arranged between the taper portion (32) and the second rope region (26). A diameter of the first rope region is smaller than a diameter of the second rope region (26). A diameter of the overlap portion (30) is greater than the diameter of the second rope region (26). A diameter of the splice region (22) generally decreases from the overlap portion (30) to the first rope region (24).
Abstract:
A belt used as a rope which as a strength higher than that of a rope of the same mass and a substantially circular cross section, and which is provided at both sides thereof with belt portions. This belt consists of a narrow woven material (10) composed of warp and weft yarn (6, 7) of synthetic fiber filaments, and has a belt body (2) extending in the lengthwise direction of the belt, a belt portion (4), and a joint portion (3) for connecting the belt body (2) and belt portion (4) together. The belt body (2) is formed by weaving core strings (5) into a hollow weave texture, and the warp yarn density factor of a hollow weave member (22) is set to not more than 0.700. The belt portion (4) has a woven structure in which the warp yarn (6) in the hollow weave member of the belt body (2) and a part or the whole of the core strings (5) in the belt body (2) are interlaced with the weft yarn. The belt portion has a width W not less than 2.0 times as large as that W &cir& _ of the belt body (2). The joint portion (3) is formed so that it transmutes to a woven structure of the belt body (2) or that of the belt portion (4) in a plurality of steps with its weaving width gradually decreasing or increasing.
