  • Patent number: 6090350
    Abstract: A system for separating constituents from a base material using RF energy which is coupled to a reaction chamber by way of a windowless transmission line. By eliminating the need for a window, traditional limitations placed on the maximum power delivered to the resonating cavity are eliminated. Thus, the only practical limitation on the RF energy which can be delivered to a resonating cavity are the ability of RF energy source to produce that energy and the ability of the resonating cavity to manage that energy.
    Type: Grant

  • Patent number: 5997607
    Abstract: A condensation chamber and method for condensing a metal connate from a metal rich gaseous mixture. The condensation chamber includes top and sidewall surfaces that together define a central bore. A gas supply is received in the bore, and as the gas begins to cool, a metal connate condensate forms on the surfaces of the condensation chamber. A moveable surface is received in the bore for removing the connate from the surfaces adjacent the bore. To facilitate removal of the connate, the surfaces adjacent the bore are heated to ensure that the connate remains substantially in the liquid state while in the condensation chamber. The moveable surface helps direct the connate into a cooling chamber supported by the condensation chamber. In the cooling chamber, the connate is cooled to a plastic state. The cooled connate may be formed into pellets and stored for later use.
