  • Patent number: 6936179
    Abstract: A method and apparatus for producing super-oxygenated water for human consumption including forcing atmospheric air through a filter to remove impurities, exposing the filtered air to ultra violet light to cleanse the air, and to form ozone and oxygen in the air, forcing the filtered air, ozone, and oxygen into a stream of flowing water to dissolve said air, ozone, and oxygen in said water, and spraying the stream of water having air, ozone, and oxygen dissolved therein into a vessel under superatmospheric pressure.
    Type: Grant
    Filed: April 15, 2003
    Date of Patent: August 30, 2005

  • Patent number: 4976210
    Abstract: A hazardous waste disposal system includes a rotary kiln heated with an atomizing burner which mixes fuel such as diesel oil with air and injects the burning mixture into the kiln. An afterburner section is similarly fueled with an atomizing burner. An upstanding scrubber receives exit gases and removes particulate matter using water spray across multiple frusto conical shaped baffles on increasing diameter. Cyclone vanes produce a spinning effect to the exit gases during scrubbing.

  • Patent number: 4522258
    Abstract: A modular well testing unit for use in hostile environments provides a plurality of modular sections providing upon assembly an enclosed structure for housing the components of the well testing unit, each of the modular sections being self-supporting and transportable. Upon assembly insulation is provided to give an internal controlled environment surrounded by a substantially continuous external shell. Access internally allows movement between adjacent modular sections by personnel, for example. A production intake allows an oil stream from an oil or gas well to be tested to be transmitted to the interior portion of the enclosure. An outlet is provided for discharging oil as well as air, gases, and liquids other than oil such as water. A plurality of well-testing, fluid-handling vessels are disposed respectively in the plurality of modular sections.

  • Patent number: 4520994
    Abstract: A high pressure gate valve apparatus provides an elongated cylindrical valve body providing a fluid conveying linear cylindrical longitudinal bore of substantially uniform configuration. A gate valving member is movable within the valve body entirely within the confines of the valve body and not projecting laterally therebeyond. The valve member is movable at generally right angles to and intersecting the fluid conveying bore with the gate valving member providing a flow opening therethrough, the valving member being movable within the valve body between open flow and closed flow positions. A pair of spaced generally parallel cylindrical drive chamber is provided on the valve body substantially parallel to the central flow conveying bore.
