Abstract: A quad or dual differential pair cable for bi-directional high speed differential signal transmission has a first differential pair of conductors and a second differential pair of conductors. The conductors extend in substantially parallel relation to one another and are electrically insulated from each other by an insulating dielectric. The dielectric and the conductors are surrounded by a conductive metal shield. The dielectric insulates the conductors both from each other and from the shield and is sufficiently crush resistant to maintain the conductors in substantially parallel relation to one another over the length of the cable, The shield may be covered with an optional jacket. Each wire of a differential pair of wires are oriented 180 degrees apart from one another. The distance between any one of the conductors and the shield is equal to or greater than the distance between that conductor and a center axis of the cable.

Abstract: A heatable hose assembly having a helically corrugated central polymer tube of polyether ether ketone wrapped with a layer of polymer tape. A means for heating the central polymer tube is arranged on the layer of high strength tape as is a means for monitoring and controlling the means for heating the central polymer tube. Surrounding the arrangement is a layer of thermal insulation and a protective jacket. The heatable hose assembly is of utility for use in systems for the monitoring of acid gases from emission stacks.

Abstract: An asymmetrically shaped jacketed coaxial electrical cable having a drain wire in which the drain wire is aligned parallel to the asymmetric edge or corner of the cable for fast and accurate termination of the cable.

Abstract: An electrical cable of conductive wire having an insulating layer of microporous polymeric material around it, followed by a coating of a polyesterpolyurethane surrounding the insulating layer, and an outer film of polyetherpolyurethane surrounding the coating.
