Abstract: A pushpull cable conduit is made by continuously moving a tubular mandrel through a crosshead extruding die, forming a tape of micro-porous polytetrafluoroethylene resin into cylindrical form covering the mandrel as it enters the extruding die, extruding an outer layer of fluid polymeric material over the cylindrical covering in the presence of heat, helically wrapping contiguous wires over said outer layer to form a wire layer, extruding an outer covering of thermoplastic material over the wire layer, and removing the tubular mandrel. The porosity of the polytetrafluoroethylene covering insures a good heat bond with the outer layer of fluid polymeric material and also provides a lubricant reservoir in its inner surface, thereby minimizing friction with the cable core and greatly reducing sound transmission.

Abstract: An actuator for an automatic transmission modulator valve which automatically changes shift speeds proportional to demand on the engine from idle to full throttle. The actuator is preferably controlled by a push-pull cable operatively connected to the throttle or accelerator, and exerts pressure on the push pin of the modulator valve in direct proportion to the travel of the throttle. The actuator utilizes balls between inclined surfaces on interfacing rotary and stationary cam plates and the cable applies rotating force through a moment arm to the rotary plate to obtain a substantial mechanical advantage in the amount of pressure applied to the push pin.

Abstract: A system for transferring motion between locations remote with respect to each other by a push-pull control cable assembly. The system employs a motion conversion unit at either or both control and controlled station, said units serving to convert rotary motion into linear motion, and vice versa. That is, a force transfer shaft is rotatably mounted in the housing of the motion conversion unit to receive, or impart, rotary motion, and the core element of the push-pull control cable assembly -- which receives, or imparts, linear motion -- extends into, or through, the unit in transversely spaced relation with respect to the shaft. That portion of the normally flexible core element which extends into, or through, the unit is made rigid to impart columnar strength. A crosshead is secured to the rigidified portion of the core element and is slidably received within a first guideway presented from the housing to minimize lateral loading to the rigidified portion of the core element.
