Abstract: A conduit formed of extruded polymeric material, which outer surfaces are continuously intrinsically lubricated by a reserve of active lubricious agents which migrate outwardly from within the composition to such surfaces.

Abstract: Disclosed is an aqueous gel lubricant, and a method for formulating the lubricant, the lubricant having, as its basic and essential components, a major proportion of water, an effective gelling amount of an anionic heteropolysaccharide, and an effective lubricating amount of an anionic emulsion of a polysiloxane polymer. Additions of effective lubricating amounts of suspended microspherical beads enhance the lubricity and a suitable anti-freeze agent enhances the lubricant's effectiveness for low temperature applications. The lubricant is particularly adapted to facilitate the installation of cables within outer ducts or conduits.

Abstract: Disclosed is ground supported automatically operated cable insulation stripping apparatus having a pair of cable clamping assemblies, one of which being adapted to substantially sever a portion of the cable insulation being removed and thereafter translated away from the other assembly to strip the so-severed portion. The clamping and unclamping of the cable is effected by cooperating jaw assemblies having mutually aligned semicircular recessed surface portions for gripping the cable, the jaw assemblies of the translatable cable clamping assembly additionally having cooperating cutting blades for severing the insulating casing, ejector pins carried by pin carrier frames of the clamping assemblies assisting in the ejection of the cable. A pneumatic system is disclosed for operating the apparatus.
