  • Split hub wheel apparatus
    Patent number: 4495032
    Abstract: A shale oil retort apparatus is provided for retorting oil shale under airtight conditions. The retort apparatus employs a split hub wheel device which allows for the axial feeding of crushed oil shale and the axial dispensing of spent oil shale. The retort apparatus utilizes a rotatable shaft on a stationary axle, said shaft containing three spokes that are set approximately equidistant apart. The spokes serve to feed raw oil shale, dip it into a hot oil bath and dispense spent oil shale out of the apparatus.

  • Linear pocket letdown device
    Patent number: 4379670
    Abstract: A system for removing material from the bottom of a pressure vessel without relieving the vessle's pressure in which a tube connected intermediate its inlet and outlet ends to the pressure vessel receives material through the connection and into pocket means carried by a conveyor running through the tube. The conveyor carries the material to the outlet or discharge of the tube. The pocket means form moving labyrinth seals at each end of the tube for preventing vessel pressure loss through the tube.
