  • Patent number: 4107034
    Abstract: An air classifier system for separating mixed materials and comprising the combination of a horizontal drum or tunnel having a feed screw therein at one end of which mixed materials are deposited for movement toward the discharge end of the drum, and means for directing a flow of air through the drum at relatively high velocity for entraining and removing light materials from the drum while permitting heavy materials to be independently moved out of the drum by the screw.
    Type: Grant
    Filed: October 1, 1976
    Date of Patent: August 15, 1978
    Assignee: Raytheon Company
    Inventors: Malcolm M. Paterson, Michael R. Grubbs, Peter J. Cambourelis, Vernon L. Schrimper
  • Patent number: 4089616
    Abstract: A steerable split roll for a road roller includes a pair of roll shells containing means by which vibratory force is applied to each. Between adjacent ends of the roll shells a "turntable" type of bearing both connects the roll shells together for rotation relative to each other and maintains them in axial alignment.
    Type: Grant

  • Patent number: 3970547
    Abstract: A rotary drum air classifier system which includes a side feed hopper by which mixed materials to be separated are fed to a screw feed which deposits the materials inside the drum for major separation into light and heavy materials, the screw feed being longitudinally adjustable and including air injection means for fluidizing the mixed materials as they are being transported to the drum and thus accomplishing a preliminary stage of air classification during the time the mixed materials are transiting the length of the feed screw.
    Type: Grant
    Filed: May 22, 1975
    Date of Patent: July 20, 1976

  • Patent number: 3938732
    Abstract: A roll crusher incorporates gas hydraulic springs to maintain the desired spacing between the crushing rolls and to provide overload protection. Featured are separate hydraulic means for backing off and then reapplying the hydraulic springs by altering their overall lengths so that roll spacing can be readily adjusted.
