  • Patent number: 6634834
    Abstract: A process and apparatus for effecting the transportation of sulfur pellets with the recovery of sulfur fines is disclosed. This is accomplished by a combination of steps and apparatus which include pumping water from a water supply into solid sulfur pellets with a jet-venturi/eductor pumping system to produce a sulfur water slurry containing sulfur pellets and sulfur fines, pumping the sulfur water slurry with one or more rotating disk/boundary layer pumps to a series of static screens to remove large lumps and impurities, a sulfur fines slurry, and a washed sulfur pellet slurry, contacting the sulfur pellet slurry with a dewatering disk to remove substantially all the remaining water, transporting the dewatered sulfur pellets to storage, pumping the sulfur fines slurry to a hydrocyclone to separate all the water from the sulfur fines, recycling the recovered water to said water supply following the addition of an alkaline neutralizing agent when needed, and recovering the sulfur fines.

  • Patent number: 6372129
    Abstract: A process and apparatus for effecting the recovery of grease and oils from an aqueous waste stream is disclosed. This is accomplished by a combination of steps which include removing coarse food solids from the waste stream, allowing the oils to separate from the water in a separation zone, removing the oil layer to a storage zone, removing the water layer to a heat recovery zone and transferring heat values from the recovery zone to the separation zone with vapor compression refrigeration. The invention saves energy by recycling the heat of the kitchen waste stream to the separation zone. The recovered oil is useful as a marketable product that can be converted into many useful products. When a fines filter is used in the process, the discharged water can be used for non-agricultural uses such as lawn watering or can be used in water closets and urinals.

  • Patent number: 6003883
    Abstract: A recreational chair converter is disclosed. The chair converter will convert a folding chair with a U shaped rear support leg from its normal use as a chair to a transport cart. The chair converter is provided with a pair of wheels mounted on an axle and has a pair of elongated segments attached to each other by means of living hinges and bolts. Each segment has two lengthwise grooves so that the pair of segments, when attached together, will form two parallel cylindrical openings which receive and hold the axle equipped with wheels and the rear support leg of a recreational chair. The pair of segments are securely attached to and are completely around the rear tubular leg of a recreational chair. There is also provided a tension strap and buckle which holds the chair securely to said pair of segments and allows the converter device to be used as a transport cart when it is desired.

  • Patent number: 4782124
    Abstract: Modified epoxy resins are prepared by the reaction of one or more epoxy resins with polycarbonate resins or oligomers. One or more monoalcohols and/or monophenols can also be used in the modification reaction. The epoxy resins also can be advanced by inclusion of a polyphenol during the reaction. The modified epoxy resins have a chain branching and/or crosslinking due to carbonate bonding of polycarbonate chain scission products to the epoxy resin. The epoxy resins are useful to make powder coatings with enhanced adhesion to metal and resistance to cathodic disbondment.
