    Abstract: To identify the need for replacement of stranded synthetic fiber ropes, preferably ropes of aramide fiber, a torsionally neutral rope construction of load-bearing fiber strands is obtained by having at least two layers of strands laid together in opposite directions so that the torsional forces in the layers of strands compensate each other. If the layers of the strands become weakened by unequal amounts due to wear or external influences, when the rope is under load and running operationally it begins to twist about its longitudinal axis. The twisting of the rope can be made visible by a colored mark or strip extending along the length of the rope to indicate twisting of the rope thereby providing visual identification of the need for replacement of the rope.

    Abstract: A steel cord having a three-layer twisted construction consisting of an innermost layer, an intermediate layer, an outermost layer, and a spiral warp and being capable of achieving an improvement in the adhesion force to rubber while reducing the number of processing steps used. In the steel cord, the innermost layer consists of 3 filaments twisted in one of left or right twist directions while having a twist pitch length of 5 to 18 mm; the intermediate layer consists of 8 filaments twisted in the same twist direction as that of the innermost layer while having a twist pitch length of 5 to 18 mm, namely, the same twist pitch length as that of the innermost layer; the outermost layer consists of 13 filaments twisted in a left or right twist direction opposite to those of the innermost and intermediate layers while having a twist pitch length of 10 to 25 mm equal to or more than those of the innermost and intermediate layers; and the spiral wrap consists of a single filament adapted to be wrapped around the outermost layer, thereby preventing the steel cord from being unwound, the filament being twisted in a twisted direction opposite to that of the outermost layer while having a twist pitch length of 3 to 10 mm. Gaps are formed among the filaments of the intermediate and outermost layers. The gaps allow rubber to penetrate easily into the steel cord therethrough.

    Abstract: An energy-absorbing towline (14) comprises an elastomeric core (16) having a set of internal polymeric strands (18) helically wound around the outer surface (20) of the core in a first direction and a set of external polymeric strands (22) helically wound around the outer surface (24) of the internal strands in a direction opposite to the first direction. There may be more internal strands than external strands in order to maintain torque balance as the cable elongates. Each of the internal and external strands consists of a plurality of filaments (30), and each external strand (22) may have fewer strand filaments than each internal strand (18) so as to aid in torque balancing. Electrical conductors (26) may be helically disposed between turns of the external or the internal strands. When the towline experiences tension, the elastomeric core elongates, as do the helixes. But the diameters of the helixes contract, so the strands themselves do not elongate. Consequently, the towline can elongate in response to tension and thereby absorb energy without placing any significant tensile stress on the electrical conductors used for electrical communication between a moving craft and a deployed drogue.

    Abstract: A wire rope, particularly a non-twistable wire rope, wherein an annulus of outer strands surrounds a wire rope center with a central strand and one or more annuli of neighboring strands surrounding the central strand. The wires of the strands in the center do not intersect each other. The entire center or at least some of its strands are densified prior to or during application of the outer strands. Alternatively, or in addition to such densification, at least some strands of the center are assembled of wires having an other than circular outline to thereby reduce the combined cross-sectional area of voids in the center.

    Abstract: A rope has a rope core formed of load-bearing aramide fiber strands laid parallel to each other in concentric layers of strands and strands of an outermost layer laid with opposite lay to the rope core. As a result of the opposite lay, the torques which occur in the layers of strands when under load cancel each other out and a non-twisting rope structure is achieved. An elastic intersheath is positioned between the oppositely laid layers of strands to protect the strands against abrasion and to transmit the torque over a wide area in the rope.
