Abstract: A method of reducing an initial stress on a cable includes stretching the cable to a first length to thereby define the initial stress. The cable has a central longitudinal axis, and includes a plurality of wires each twisted around the axis and formed from a shape memory alloy transitionable in response to a signal between a first state wherein each of the wires has a first temperature-dependent length, and a second state wherein each of the wires has a second temperature-dependent length that is less than the first. After stretching, the method includes activating the alloy by exposing the alloy to the signal such that the alloy transitions from the first to the second temperature-dependent state. Concurrent to activating, the method includes elongating the cable to a second length that is greater than the first to define a second stress on the cable that is less than the first.

Abstract: A mooring loop is provided for use with connecting a mooring line to a bollard. The mooring loop may stretch and function as a time delay fuse when excessive loads are applied to the mooring line. The mooring loop is comprised of a reactive fiber component in the shape of a continuous loop that includes a plurality of at least one of: an undrawn hydrophobic polymer fiber or a substantially undrawn hydrophobic polymer fiber. At least two jackets are in surrounding relation to portions of the reactive fiber component. The at least two jackets include respective end portions which overlap. As the mooring loop stretches, a visual indicator on an end portion of one of the jackets pulls out of and away from the end portion of the other one of the jackets. The visual indicator serves as a warning that excessive loads are being applied to the mooring line.

Abstract: A method and device for handling an elongate strength member. In the method, an elongate strength member with a plurality of elongate composite rods, or metal wires or plastic fibers are bundled together with the composite rods, or metal wires, or plastic fibers in a generally parallel and untwisted and un-spiraled arrangement when the elongate strength member is extended along a generally straight path, wherein the composite rods are longitudinally and rotatably moveable relative to each other. It is then twisted relative to a longitudinal dimension of the elongate strength member and the path of the elongate strength member is curved, such as by coiling.

Abstract: An improved starter pull cord for an internal combustion engine having significantly increased stiffness, resistance to wear, and strength, the starter pull cord being comprised of rope having high modulus fibers selected from the group consisting of liquid crystal polymer (LCP), aramid, and high-modulus polyethylene (HMPE). The higher stiffness of the high modulus starter pull cords of the present invention translates to greater impetus during the act of pull starting the engine, which is apt to start more quickly than with starter pull cords of the prior art. The increased strength of the high modulus starter pull cords translates to fewer breakages over the lifetime of an engine and therefore increased reliability.
