  • Patent number: 9761413
    Abstract: The present invention provides a glow discharge assembly that includes an electrically conductive cylindrical screen, a flange assembly, an electrode, an insulator and a non-conductive granular material. The electrically conductive cylindrical screen has an open end and a closed end. The flange assembly is attached to and electrically connected to the open end of the electrically conductive cylindrical screen. The flange assembly has a hole with a first diameter aligned with a longitudinal axis of the electrically conductive cylindrical screen. The electrode is aligned with the longitudinal axis of the electrically conductive cylindrical screen and extends through the hole of the flange assembly into the electrically conductive cylindrical screen. The insulator seals the hole of the flange assembly around the electrode and maintains a substantially equidistant gap between the electrically conductive cylindrical screen and the electrode.

  • Patent number: 9699879
    Abstract: An apparatus and method sinters or partially sinters green pellets in a selected temperature range to make proppant particles as the green pellets pass between an electrical arc and a gas flowing in the vortex path and exit an underflow of a vessel. The vessel has an overflow disposed in a first end, an underflow disposed in a second end, a middle portion having a circular cross-section disposed between the first end and the second end, and a tangential inlet proximate to the first end such that a gas from the tangential inlet flows along a vortex path from the first end to the second end of the vessel. A first electrode extends through the overflow and a second electrode extends through the underflow. The electrodes are used to create the open electrical arc. One or more feed tubes extend through the overflow proximate to the first electrode.
