  • Patent number: 8869988
    Abstract: A cooler for particulate product includes a substantially enclosed housing. A first cooling screen is disposed in the housing and is configured to receive the product. The first cooling screen is configured to move the product along a surface by gravity when the first cooling screen vibrated. A duct is coupled to the first cooling screen to move cooling fluid through the first cooling screen. A second cooling screen is disposed in the housing below the first screen and is configured to receive the product after discharge from the first screen. The second screen is configured to move the particulate product along a surface when vibrated. A second duct is coupled to the second screen to move cooling fluid through the screen. A collector receives the particulate product after moving along a surface of the second screen. A vibrator is coupled to the housing and vibrates the housing.

  • Patent number: 7571816
    Abstract: A screening and sorting assembly for coal particles includes a bin for receiving crushed coal. The bin is provided with a weir over which the coal particles are passed onto a pivoted screen assembly having a plurality of openings therethrough for sorting the coal particles. A cam arrangement is provided for varying the angle of the screening assembly relative to the horizontal to vary the speed of flow of the coal particles downwardly over the screening assembly.

  • Patent number: 5394833
    Abstract: An animal waste disposal apparatus that consists of two cooperating hoppers on a supporting frame separated by an angled screen member so that animal waste is automatically separated from litter material when the apparatus is inverted by rotation. The animal waste is then directed through a chute into a disposable collector so the pet owner does not have to handle an unsanitary litter box. The waste disposal apparatus is fully enclosed to eliminate the unpleasant odor and appearance normally associated with litter boxes and the pet owner does not have to see or handle animal waste.

  • Patent number: 5168834
    Abstract: A litter handling system that includes two receptacles, each of which is capable of holding particulate litter and the juxtaposed edges of which are shaped to be releasably clamped to opposite surfaces of a separator that has elongated openings, to separate reusable particulate litter from clumps therein as the clamped assembly is rolled over to transfer the particulate litter, which has clumps in it, from a first one of the receptacles to the other.

  • Patent number: 5012765
    Abstract: An improved animal waste collection and screening device having two litter pans in opposed orientation, an opened face of a first litter pan in facing arrangement with an open face of the second litter pan with a screen member in interposed relationship between the opposing litter pans. Tracks on the screen member guide and receive the first pan on a first face side of the screen member and guide and receive the second pan on a second face side of the screen member, holding the two pans securely together. The screen member provides on one longitudinal end a handle and two catches, one catch for engaging each said litter pan when each said litter pan is fully received by said tracks and properly oriented with respect to the screen member and the respective other litter pan. The catches are located approximate to the handle for convenient one hand engagement and disengagement, and are self engaging and manually disengaging devices.

  • Patent number: 4339043
    Abstract: A self-contained revolving trommel classifying and sluice type recovery plant is described. The trommel screen is perforated and provided with helical corrugations to subject received placer material to several forces which, combined with sufficient water added through provided nozzles, break up the placer material and expose values to the trommel perforations. The perforations are arranged in a continuous pattern within the length of the trommel. Classified material drops through the perforations into an elongated sluice, along with all the accumulated water used in the classifying-washing process. Values are separated from tailings by corrugations along the sluice length. A suction pump operates with a suction hose and settling tank to recover values from the sluice during operation.

  • Patent number: 4325822
    Abstract: An animal waste collection and disposal device of the type which contains a litter material into which animal waste matter is deposited including a pair of opposed receptacles. Each of the receptacles has wall portions defining a litter-receiving chamber which is open over at least a portion of one major planar face of the receptacle, with the open portion of each receptacle being in facing relation to the open portion of the other receptacle. A screen member is positioned in interposed relation between the opposed receptacles. Tracks on the screen member slidably receive the receptacles to interlockingly detachably engage the receptacles with the screen member to permit inversion of the assembled receptacles to, in turn, transfilter the granular litter material through the screen. Abutment members limit the longitudinal sliding movement of the receptacles relative to the screen member to align the receptacles relative to the screen member and relative to each other.
