  • Publication number: 20100201049
    Abstract: A thermally efficient cover for the molten metal held in a furnace, tundish, ladle, crucible or other containment vessel. Through substantially horizontal movement, this cover allows for periodic removal, particularly by retraction, for accessing contents of that furnace from a top aperture in the containment vessel. This invention further relates to a covered furnace system and methods of use.

  • Patent number: 7288574
    Abstract: A two-phase mixture is provided having a dissolved gas and a suspension of bubbles in a liquid. Methods for making, maintaining, and using the two-phase mixture are also provided. The gas molecules may be introduced into the liquid at a high velocity under elevated pressure to form a supersaturated solution that retains the dissolved gas concentration in solution when the solution is exposed to ambient conditions. The mixture may be used in a number of applications where high concentrations of gas must be retained in solution during prolonged exposure to ambient conditions. An example of use is the treatment of wounds to non-surgically remove dead, devitalized, contaminated and foreign matter from tissue cells. The mixture may be combined with a plastic to encapsulate the suspension of bubbles to minimize liberation of the gas bubbles from the mixture.

  • Patent number: 7033538
    Abstract: A method of heating molten aluminum flowing in a heated trough member comprising the steps of providing a source of molten aluminum and providing a rough member comprised of a first side and a second side, the first and the second sides having outside surfaces, the sides formed from a ceramic material resistant to attack by molten aluminum. The first side and second side have heating element receptacles provided therein with protection tubes provided in the receptacles. The protection tubes are comprised of a refractory selected from the group consisting of mullite, boron nitride, silicon nitride, silicon carbide, graphite, silicon aluminum oxynitride or a metal selected from KovarĀ® and titanium. Electric heating elements are positioned in the tubes. Molten aluminum is flowed along the trough member from the source and electric power is passed to the heating elements to heat the molten aluminum as it flows along the trough member.

  • Patent number: 6585928
    Abstract: A method of dispensing or pouring molten metal, e.g., aluminum, from a container or vessel, the flow rate controlled to minimize splashing of the molten aluminum exiting the container, the method comprising the steps of providing a container for containing molten metal, the container having an outlet for dispensing molten metal therefrom and providing a body of molten aluminum in the container, the body having a top surface. A pressure lower than atmospheric pressure is maintained on the surface of the body in the container vessel for purposes of controlling the flow of molten metal through said outlet. Molten metal is dispensed through the outlet by increasing the pressure maintained in the container towards atmospheric pressure.
