Abstract: A flexible, thermoplastic hose for high pressure and high velocity flow is provided with a flexible braided reinforcement layer with a static drain therein for conducting static electricity towards a ground. This is achieved by having at least one textile fiber yarn with conductive fibers therein braided with non-conducting textile yarns to form the braided reinforcement layer. The preferred conducting fiber yarn is formed with metal fibers as well as plastic fibers. A method of manufacture of the hose comprises providing electrical conducting yarns and non-conducting yarns in a braiding machine and braiding them about a tube having a hollow bore through which fluid flows. An abrasion resistant outer cover layer of polyurethane is extruded over the braided layer having the drain therein. For higher pressure applications, a second braided reinforcement layer may also be provided over the inner braided layer having the electrically conductive yarns.

Abstract: A lubricant retaining face seal useful, for example, in a pivoting mechanical connection, and having a flexible compressible annular sealing lip comprising a conical sealing surface to provide significant annular area of sealing engagement between seal and mating surface. A modified form includes an O-ring around the sealing lip to insure sealing under light loads and to overcome compression set of the lip.
