Abstract: An assembly including a span of microwave signals flexible coaxial line, or other form energy transmission media, is provided with generally coextensive, non-metallic longitudinal strength strands to render greater tensile strength to the assembly. Marginal axial end sections of a coaxial cable span are potted in respective polyurethane grip foundation having longitudinal grooves. The grip foundations are inserted into an open-mesh-sleeve type cable-end grip device. The strength strands are seated in the grooves and interlaced in and out of the openings in the open-mesh-sleeves of the grip devices. Co-adjacent marginal end portions of the strength strands are bundled beyond the interlacing, and knotted to the open-mesh-sleeves of the grip devices. In forming the knots the bundled marginal end portions of the strength strands are entwined and bound together and with a pair of the crossing strands of the open-mesh-sleeve.

Abstract: The present invention relates to a cable section assembly for marine applications having a core structure, such as a buoyant cable antenna interim manufacturing step subassembly, and a protective casing formed from a heat shrinkable tubing which together with the interim subassembly forms a complete assembly. For buoyant cable assembly applications the interim subassembly is at least partially formed of polyurethane material having glass microballoons distributed therein, with such material in any event occupying an outer layer portion of the subassembly. The cable section assembly of the present invention is formed by providing a length of heat shrinkable flexible tubing, inflating or expanding the heat shrinkable tubing to its approximate full diameter, inserting the core structure into the length of tubing, and shrinking the tubing around the core structure.

Abstract: A cable sectional assembly houses an electrically concatenated series of electronic circuit modules and has electric hook-up media interspersed between the modules. Each run of interspersed hook-up media is surrounded by a flexible tubular member, which is oversized to allow movement of the hook-up media without restriction under flexing of the assembly. The assembly is a construction and arrangement of two forms of moldingly bonded encapsulations. The first of these forms is made of a hard encapsulant and forms a unitary encapsulation local to each electronic module which (i) encapsulates the circuit module and associated electrical coupling connections between the adjacent end of each individual run of an adjacent interspersed run of media and an electrical terminal of the module, and (ii) is securely bonded to the adjacent marginal end portions of the tubular members which surround the adjacent interspersed runs of hook-up media.
