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: A high volume rotary selector valve having a modular structure is disclosed. The disclosed device operates to select one of a plurality of individual source lines of pressurized oil, gas, or other matter to divert the contents of the selected line to a predetermined destination for metering, testing, or sampling without interrupting the flow from other source lines. The modular design permits a large number of input lines to be attached to the valve without a corresponding increase in the valve's diameter or material thickness. Additionally, the modular design affords the user the ability to upgrade an existing selector valve system to increase the number of inlet ports, change the size of the inlet or outlet ports, or change the inlet or outlet port connector types.
