  • Hand guard
    Patent number: 9358694
    Abstract: A hand guard strap which mounts to and is held onto the handle of a tool, such as a knife, by sliding onto the handle at distal and proximal ends, the hand guard being held in a secured position by means of spring tension in the strap.
    Type: Grant
    Filed: June 3, 2014
    Date of Patent: June 7, 2016
    Inventors: Sean Heumann, William L Heumann
  • Cyclone separator arrangement
    Patent number: 8512451
    Abstract: A cyclone separator arrangement is made by forming a hollow cylindrical wall, making an L-shaped cut beginning at a first open end of the wall to form a flap, bending the flap inwardly to form a tangential inlet, enclosing the open end of the wall, and providing an outlet tube extending through the first end into the interior of said cylindrical wall along the central longitudinal axis.
    Type: Grant

    Date of Patent: August 20, 2013
    Inventor: William L. Heumann
  • Cyclone separator with rotating collection chamber
    Patent number: 7708808
    Abstract: A cyclone separator including a gas inlet, a gas outlet, and a particle outlet opening, wherein a rotatable particle collection chamber is in fluid communication with the particle outlet opening.
    Type: Grant
    Filed: June 1, 2007
    Date of Patent: May 4, 2010
    Assignee: Fisher-Klosterman, Inc.
    Inventor: William L. Heumann
  • Cyclone separator with surface vanes
    Patent number: 6837912
    Abstract: A cyclone separator including vanes along the inside wall of the conical section of the separator to regulate the pitch and thus the axial velocity of the gas flow stream in the separator. By adjusting the pitch of the gas flow stream, the collection efficiency of the separator can be optimized so as to minimize the amount of dust particles which are re-entrained in the gas flow stream exiting the separator.

  • Wear indicator for refractory linings
    Patent number: 6686752
    Abstract: A vessel, as for a cyclone separator, includes a continuous electrical conductor embedded in the wall of the vessel for sensing when the lining has eroded.
    Type: Grant

  • Method for cyclone conversion for a fluidized bed
    Patent number: 5907910
    Abstract: A method has been found to improve the efficiency of a cyclone system for a fluidized bed. The typical plurality of cyclones arranged in series in communication with the fluidized bed is replaced by a plurality of similarly-sized cyclones arranged in parallel, so that the residence time in each of the cyclones is greater than it was in the original system, thereby greatly improving the recovery of particulate material while greatly reducing the energy consumption of the system.

  • Fluidized bed wtih cyclone
    Patent number: 5612003
    Abstract: A fluidized bed vessel includes a cyclone which has a leg for returning particulate material to the bed, and an eductor at the bottom of the leg for providing the gas to fluidize the bed and for inducing a downward flow in the leg to provide greater particulate separation from the gas in the cyclone.
