    摘要: This invention relates generally to cable assemblies, and more particularly to flexible cable assemblies of the type used in automobiles for transmitting rotary or linear motion along a predetermined path. In a particular aspect, the present invention relates to abrasion-resistant fluorocarbon polymer composites, such as polytetrafluoroethylene (“PTFE”) composites, having an unexpectedly high frictional efficiency under high load conditions and after long cycle times. The present invention relates to abrasion-resistant, anti-friction tubing formed from such composites, and to uses of such tubing as a liner for flexible, motion transmitting cable assemblies.

    摘要: A method and apparatus for pressure welding together novel aluminum or magnesium workpieces. Edges of workpieces to be pressure welded together are aligned with each other by abutment and one workpiece retracted from the other a predetermined distance to define an open channel between the edges. The workpiece edges are quickly heated to a temperature within the range of from about 200.degree. to 900.degree. F. by passing a uniform flow of heating gases through the channel such that the edge tip and sides of each workpiece are softened while the edge inner cores remain cooler and harder with their mechanical properties unaffected by the heat and the workpieces then moved into abutment with each other to close the channel and immediately pressed together under high pressure for expulsion of softened metal containing deleterious materials such as surface oxides and creation of a solid-phase weld bond between the relatively cool and hard inner cores. An air curtain can be provided to improve control of the heating of the workpieces and to enhance pressure welding together of workpieces of different gauges and of different metals, such as welding of aluminum to magnesium alloys.
