  • Patent number: 5092950
    Abstract: A molding apparatus and method are provided for molding hollow articles. Resin impregnated fibers are passed through a mold cavity as defined by a heated die and around a mandrel which extends through the mold cavity. The mandrel is stabilized by a mandrel stabilizer fixedly positioned downstream from the inlet end of the die. The mandrel stabilizer includes a plurality of elongated members spaced around the mandrel, wherein each elongated member has an end in contact with the outer surface of the mandrel.

  • Patent number: 4555637
    Abstract: A high speed turbogenerator functionally combining, in one machine, an electrical generator and an expansion turbine. The electrical generator itself has a shaft supported on two bearings and the expansion turbine comprises an expander wheel overhung on the generator shaft and which rotates as a high pressure gas is let down in the expansion turbine to a lower pressure at a minimum predetermined flow rate and pressure drop. The shaft operates at speeds of about 6,000 rpm to 32,000 rpm, preferably at the higher end of such range, i.e. 20,000 to 24,000 rpm. The unit is sufficiently compact that a new use for the electrical generator is to modify the same such that the entire high speed turbogenerator is contained within the conduit carrying the gas to be let down in pressure and only electrical wires need be led through the conduit. The integrity of the conduit is thus retained to the extent possible and only a high pressure cable fitting extends through the conduit.

  • Patent number: 4273390
    Abstract: The present invention pertains to a thrust bearing system including a thrust bearing structure having at least one pair of opposed bearing faces defining a bearing space therebetween, and a sub-system for delivering lubricant to the bearing space. A load sensor is provided in association with the bearing structure for determining the loads on the bearing faces. A thrust compensation sub-system is operably associated with the load sensor. This thrust compensation sub-system is operative, upon sensing by the load sensor of a thrust load on the bearing faces in excess of a predetermined limit, to increase the pressure of lubricant being delivered to the bearing space.
