  • Heat treatment apparatus and methods for thermally processing a substrate using a pressurized gaseous environment
    Patent number: 7665917
    Abstract: Apparatus and methods for heating a substrate in a pressurized environment inside of a thermal processing system. The substrate is placed in a gaseous environment inside a processing chamber of the thermal processing system. The substrate is supported in the gaseous environment. The gas pressure inside the processing chamber is increased above atmospheric pressure, which increases the temperature of the gaseous environment. Heat is transferred from the pressurized gaseous environment to the substrate for thermally processing a layer on the substrate.

  • Method of filtering oil from oil-and-water emulsions
    Patent number: 4309289
    Abstract: A method of separating an oil-and-water phase from an oil-and-water emulsion, which method comprises passing the emulsion first through a wall of a prefilter composed first of fibres having an energy of adhesion of from 2 to 50 ergs/cm.sup.2 to form larger oil droplets, and, thereafter, passing the larger oil droplets and the emulsion through adjacent layers of glass fibres, to separate the oil phase from the oil-and-water emulsion, and then collecting and removing the oil phase, while permitting the passage of an essentially oil-free water phase of the emulsion from the prefilter.
