    Abstract: The present invention is directed to a tickler impeller and agitation system for use in stirred slurry reactors and storage tanks. The tickler impeller when mounted on a shaft is effective for providing an inward and downward swirl in a slurry medium which directs solids suspended in the slurry towards the bottom of the tank and towards the shaft on which the impeller is mounted. Directing solids suspended in a slurry downwards and towards the center of the tank rather than pushing those solids away from the center reduces solid deposits on the side of the tank, facilitates draining of the tank, and reduces nozzle starving and pump starvation.

  • Patent number: 6367959
    Abstract: A water blending apparatus for use in conditioning foundry sand. The apparatus creates a vertical sand stream flow path which increases the surface area of the sand stream and allows water to be applied to both sides of the sand stream rather than a single side, as known with conventional water mixing apparatus. In addition, the blending apparatus includes a housing inside which a pair of mixers thoroughly mix the wetted sand. Because the mixers are not positioned in-line with the main sand processing flow, as in conventional apparatus, the mixing time is not dependent upon the speed of the conveyor, and therefore mixing time may be increased. Furthermore, the agitators positioned inside the housing have a more efficient active area since a smaller clearance space is required than with over-the-conveyor style mixing devices, which must avoid contact with the conveyor belt. As a result, the sand may be cooled more quickly due to increased initial water coverage.

  • Patent number: 5707448
    Abstract: Substantially uniform distribution of a particulate composition such as a seasoning or spice, on both the top and bottom surfaces of baked good or snack pieces is achieved by applying the composition as a curtain or sheet from within a housing as the substrate pieces are transported and tumbled by counterrotating brushes. The curtain or sheet extends in the direction of the longitudinal axis of the longitudinal cavity through which the substrate pieces are transported. The apparatus includes a housing having a raised portion for enclosing and permitting the curtain or sheet to disperse in a direction transverse to the longitudinal axis of the housing cavity as the composition descends towards the baked good or snack pieces. A lowered portion, downstream of the raised portion of the housing prevents escape of airborne particulate composition to the atmosphere through the baked good or snack piece outlet.
