  • Patent number: 7659489
    Abstract: Plasma ignition and cooling apparatus and methods for plasma systems are described. An apparatus can include a vessel and at least one ignition electrode adjacent to the vessel. A total length of a dimension of the at least one ignition electrode is greater than 10% of a length of the vessel's channel. The apparatus can include a dielectric toroidal vessel, a heat sink having multiple segments urged toward the vessel by a spring-loaded mechanism, and a thermal interface between the vessel and the heat sink. A method can include providing a gas having a flow rate and a pressure and directing a portion of the flow rate of the gas into a vessel channel. The gas is ignited in the channel while the remaining portion of the flow rate is directed away from the channel.
    Type: Grant

  • Patent number: 7073771
    Abstract: A valve assembly for controlling the flow of a predetermined fluid, including a tube having an open end forming an outlet port, and wherein the tube is made of a material that is porous with respect to the predetermined fluid, an outer wall forming a fluid chamber coaxially surrounding the porous tube and including an inlet port, and a valve member made of non-porous material received for sliding movement within the porous tube. Sliding movement of the valve member within the tube and towards the open end of the tube reduces the flow of the predetermined fluid from the fluid chamber, through the porous tube and through the outlet of the valve assembly, while sliding movement of the valve member within the tube and away from the open end of the tube increases the flow of the predetermined fluid from the fluid chamber, through the porous tube and through the outlet of the valve assembly.
