Abstract: A coaxial cable is provided with a specially prepared precoat layer that facilitates removal of the precoat layer when the end of the cable is cored in preparation for receiving a connector. The cable includes an inner conductor; a foam polyolefin dielectric layer surrounding the inner conductor; an outer conductor surrounding said dielectric layer; and a precoat layer disposed between the inner conductor and the dielectric layer. The precoat layer forms a first bond interface with the inner conductor and a second bond interface with the dielectric layer, wherein the ratio of the axial shear adhesion force of the first (“A”) bond to the axial shear adhesive force of the second (“B”) bond is less than 1, and wherein the ratio of the axial shear adhesion force of the “A” bond formed by the precoat layer between the inner conductor to the dielectric layer to the rotational shear adhesion force of the bond is 5 or greater.

Abstract: The present invention is a corrosion-protected cable, a method of making a corrosion-inhibiting cable, and a corrosion-inhibiting composition. The corrosion-inhibiting composition includes a water-insoluble corrosion-inhibiting compound dispersed in an oil, and a stabilizer selected from the group consisting of propylene based glycol ethers, propylene based glycol ether acetates, ethylene based glycol ethers and ethylene based glycol ether acetates. The corrosion-inhibiting composition is preferably applied to the outer conductor of the coaxial cable, e.g., by wiping or by immersion, and heated to provide a corrosion-inhibiting coating that is not tacky or greasy.

Abstract: A method of making a coaxial cable includes forming a conductive tube and setting a settable material therein to define an inner conductor. Forming may include advancing a conductive strip and bending it into a tube having a longitudinal seam. The settable material may be dispensed onto the conductive strip continuously with the forming. Alternately, the settable material may be dispensed onto the conductive strip prior to advancing. The dispensing may use a puller cord as the settable material or carrying some or all of the settable material. The method may further include forming a dielectric layer surrounding the inner conductor, and forming an outer conductor surrounding the dielectric layer.

Abstract: An electrical communications element having a foamed plastic insultation extruded about a conductor with said insulation including at least one component with more than 20% by weight of an ultra-high die swell ratio polymer (UHDSRP), preferably around 15% by weight. The UHDSRP is defined as greater than 55% die swell ratio and more preferably greater than 65% die swell ratio. The insulation also preferably includes at least a second component with a high degree of stress crack resistance, such that the combination of (minimally) these polymers will yield an insulation layer that has a unique combination of physical propeties yielding a high degree of foaming, small uniform cell structure, characteristically lower attenuation, and stress crack resistance capable of withstanding greater than 100 hours at 100° C. while coiled at a stress level of 1 times the insulation outside diameter without failure (cracking).

Abstract: The present invention is a connecting web for side-by-side cables that eliminates the need for the use of slitting tools. The present invention includes a first elongate cable, a second elongate cable in parallel spaced apart relation from said first elongate cable and a connecting web between the first elongate cable and the second elongate cable. The connecting web is connected to the first elongate cable along a first surface and to the second elongate cable along a second surface and is capable of being pulled away from the first elongate cable or the second elongate cable without leaving a residue of the connecting web on either cable that will prevent a connector or bulkhead grommet from properly sealing around the cables. Thus, the connecting web can be removed without damaging the cables to provide good connectorization between the side-by-side cables and other cables.

Abstract: A jumper coaxial cable assembly includes a jumper coaxial cable and at least one solder-type connector secured thereto. The cable may include an outer conductor, which, in turn, includes aluminum with a tin layer thereon. The tin layer permits an aluminum outer conductor to be used, yet facilitates soldering of the solder-type connector onto the outer conductor. The tin layer may be a tin alloy, such as a tin/lead alloy, for example. The outer conductor may have a continuous, non-braided, tubular shape, and the tin layer may extend continuously along an entire length of the outer conductor. The tin layer may be readily formed by tin plating during manufacturing of the jumper coaxial cable. The jumper coaxial cable assembly may be joined to a main coaxial cable and/or to electronic equipment.
