Patents by Inventor Michael E. Rivir

Michael E. Rivir has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus Including at Least an Impeller or Diverter and for Dispensing Carbon Dioxide Particles and Method of Use
    Publication number: 20140110510
    Abstract: Carbon dioxide or any suitable material is dispensed by a system into one or more containers. An impeller within a transport produces carbon dioxide particles at one or more desired sizes. Particles sized to be sufficiently small enough to still maintain particle integrity are produced and advance through the transport, while particles of insufficient integrity are directed toward a divert and a diverter prevents the insufficient particles from being misdirected into a separate transport passageway.

  • Particle blast apparatus
    Patent number: 7950984
    Abstract: A particle blast apparatus includes a hopper assembly, which is mechanically isolated from the rest of the particle blast system. Energy is imparted to the hopper by an impulse assembly, which preferably is mounted directly to the hopper. The hopper is mounted to the apparatus on a slide assembly, which allows the hopper to be moved to a second position at which particles may be discharged from the hopper exit away from the particle feeder.

  • Pivoting hopper for particle blast apparatus
    Publication number: 20090156102
    Abstract: A particle blast apparatus has a pivoting hopper, allowing the hopper exit to move from or between a first position at which the exit is aligned with the feeder entrance to a second position where the hopper exit is not aligned as such. The hopper may emptied or cleared in this manner. The hopper may be provided with a device configured to impart energy to the hopper while the hopper exit is located at the second position.

  • Feeder assembly for particle blast system
    Patent number: 7112120
    Abstract: A particle blast system includes a feeder assembly having a rotor with a plurality of pockets formed in the peripheral surface. The transport gas flowpath includes the pockets, such that substantially all transport gas flows through the pockets. The seal adjacent the peripheral surface is actuated by the transport gas pressure to urge its sealing surface against the rotor's peripheral surface. At start up, there is no substantial pressure between the seal and the rotor, reducing start up torque requirements.
