Abstract: The present invention relates to a cable protector for underwater craft remote-controlled by cable. The function of the cable protector is to protect the operating cable of the underwater craft against wearing and catching on a surface mother-ship from which the craft is operated. The cable protector guides the operating cable out to such a great depth that it runs clear of the ship. At the same time, the cable protector allows the cable to run out in any chosen direction, while limiting a deflection angle at which the operating cable leaves the cable protector. The cable protector includes telescopically acting helical springs and a link system at a lower portion which prevents the operating cable from bending too tightly while it ensures that the cable runs out in the direction of the underwater craft.

Abstract: Modern synthetic fibers, e.g. made of aromatic polyamides of high tensile strength have not achieved their potential for use as heavy-duty cables because of their smooth surface which gives rise to considerable difficulties in the transfer of high tensile forces, since they slip out of the clamping sleeves, and other force-transfer means based upon static friction, before reaching their ultimate tensile strength. This problem was solved in the invention by applying to the force-transmitting region thereof an impregnating material which breaks down into powder in the area to which the stress is applied, when the compressive or flexural stress exceeds the ultimate stress limit of the impregnating material. Particularly suitable for this purpose are natural resins, more particularly colophonium.
