  • Patent number: 5758467
    Abstract: A modular construction member for the construction of decking, flooring, roofing, and the like, including a matable connector formed integrally with the construction member for connecting successive deck members to form a deck assembly. The modular construction member includes a gutter portion and a groove portion, which may be inter-connected to provide a substantially water-proof structure. A separate fastener may be passed through the gutter portion, the groove portion, and into a subfloor to further secure the structure and to withstand upward forces from, for example, wave action in a marine environment.

  • Patent number: 5680885
    Abstract: An improved method of rehabilitating a conduit which is in a damaged or deteriorated state. A lining hose, having a resin absorbing inner layer which is soaked with an excess volume of resin, is expanded and shaped to conformingly line a conduit by inverting a calibration hose under fluid pressure inside the lining hose. The calibration hose is comprised of a resin-absorbent layer and an impermeable layer that outwardly adjoins and surrounds the resin-absorbent layer. After inversion, the resin absorbent layer of the calibration hose contacts and adheres to the resin impregnated inner layer of the lining hose and is impregnated in situ with a portion of the excess volume of resin from the lining hose. Upon curing, the calibration hose becomes an integral part of the liner.

  • Patent number: 5653555
    Abstract: A method of lining a pipe conduit to provide superior corrosion resistance. A flexible lining hose, having a resin absorbent layer which has been introduced with a volume of high strength resin, is first positioned inside of the conduit. The lining hose is then expanded into contact with the inner diameter of the conduit by inverting a calibration hose. The calibration hose has an impermeable membrane and a layer of resin absorbent material that has been introduced with a volume of corrosion resistant resin. The calibration hose is inverted by use of fluid pressure inside the lining hose, the fluid pressure being exerted against the impermeable membrane of the calibration hose. The resin layers are then cured by the application of a heated fluid until the lining hose and the calibration hose form a unitary rigid self supporting liner.

  • Patent number: 5628183
    Abstract: A process and equipment for generating useful power comprising a special split stream heat recovery boiler 108 in combination with a gas turbine 20 and a steam turbine 80 to form a combined cycle. A steam-injected gas turbine 20 and alternately a condensing steam turbine 116 may be utilized. A topping high temperature and high pressure topping steam turbine 80 optionally may be included. Chemical heat recuperation via natural gas reformation may be incorporated within the boiler 108 to increase cycle efficiency further and to lower NOx formation without excess CO. The heat recovery boiler 206 yields increased efficiency and power output heretofore unexpected for the combined cycle compared to conventional combined cycle equipment.

  • Patent number: 5477887
    Abstract: A tubular liner for use in softlining methods of pipe rehabilitation. The tubular liner is constructed of plastic materials or laminates of plastic material which have one or more resin-absorbing layers. The tubular liner of the present invention is made by stitching together the faces of the liner material to form a tube. The seam of the tube is then sealed and the sealed seam is fused to the tube. The resulting structure provides a durable tubular liner that resists rupture or leakage of the seam during use in pipe rehabilitation operations.
