Abstract: A graduated friction anchor ring for a coupling mounted on an end of a composite pipe having a pipe core and an aramid fiber layer, the aramid fiber layer possessing poor crush resistance properties and the graduated friction anchor ring being integrally positioned within the coupling to securely and delicately anchor the aramid fiber layer in conjunction with a wedge ring. The graduated friction anchor ring comprises an anchor ring, having outer and inner surfaces and an end portion connecting the surfaces, the inner surface being inclined with respect to the surface of the wedge ring, the aramid fiber layer being positioned intermediate the anchor ring and the pipe core, the wedge ring being wedged within the pipe core to wedge the aramid fiber layer between the pipe core and the anchor ring to generate graduated compression along the aramid fiber layer in a longitudinal direction.

Abstract: A coupling combination comprising a ferrule ring having a portion outwardly of the outer surface of said pipe and having an integral deformable ferrule arm extending longitudinally therefrom adjacent to the outer surface of the pipe, the ring being placed over the pipe such that the ring surrounds an end portion thereof; a cam ring also located outwardly of the outer surface of the pipe and longitudinally placed from the deformable ferrule arm, and having a curved surface arranged to deform the ferrule arm into the pipe upon longitudinal movement of the cam ring against the ferrule; and a plurality of bolts passing through a portion of the cam ring and into the ferrule ring for affecting such longitudinal movement.

Abstract: A flexible composite pipe capable of being wound on a reel and quickly deployed at low cost while floating empty and carrying water from one location to another and being rewound after use, the pipe having a minimum burst strength of about 3,000 psi, a minimum tensile strength of about 130,000 lbs.

Abstract: A coupling for joining two sections of an electric power cable, each power cable section having an inner conductor, an insulating sheath about the inner conductor, an armored winding layer comprised of a plurality of wrapped armor rods and an insulating layer about the armored winding layer, is provided. The coupling includes an inner conductor splice housing, two armored winding termination housings lockably attached to the ends of the splice housing, means for mechanically anchoring the armor rods from a cable section within an armored winding termination housing, means for electrically connecting the armor rods to the anchoring means so that the armor rods are electrically insulated from the armored winding termination housing as well as the inner conductor, and means for electrically securing the anchoring means in one termination housing to the anchoring means in the other termination housing.
