Abstract: Described herein are splitters for holding and distributing input material to one or more decks of a gyratory sifter, where the splitter distributes approximately an equal amount of input material to each deck. An exemplary splitter may include a bottom surface, a sidewall, and one or more openings through the sidewall. Each opening may include a plurality of slits, allowing input material to pass therethrough. Where multiple openings are provided through the sidewall, the openings may be evenly spaced and have an equivalent area. The bottom surface may be substantially circular, and the sidewall may extend perpendicularly from the edges of the bottom surface. An exemplary splitter may be able to receive and distribute the input material when a gyratory force acts on the gyratory sifter on which the splitter is installed.

Abstract: A spiral concentrator has a spiral trough (2.001) has a concentrate gutter (2.010) and a pocket (2.008) located near the outer edge of the gutter. An inflatable bladder (2.012) is located in the pocket and can be deformed from a first state in which the bladder does not interfere with the flow of the slurry, to a second state, in which the bladder diverts the concentrate towards a concentrate gutter (2.101). Alternatively, a spiral trough has a deformable device that sits above and separate from the trough and acts as a flow diverter. As the device changes form, shape or state, it gradually contacts the trough or flow diverting more or less concentrate in a controlled manner.

Abstract: Apparatus for removing debris from a fluidized sand bed. One or more troughs extend radially from a vertical shaft. Associated with each trough is a perforated chute. The apparatus is placed into the fluidized bed of sand, and rotated. As the apparatus rotates, the perforated chute sifts, or separates, debris from the fluidized sand. That is, the fluidized sand flows through the perforations, but the debris does not. When the apparatus is removed from the fluidized bed, the debris tumbles down the chute, into the troughs, if it has not already done so, and is captures.

Abstract: The device selectively separates and removes larger sized objects from a mixture of larger and smaller sized objects, such as soiled litter and animal waste from surrounding clean litter. The device has a rotating chamber which contains the mixture of larger and smaller sized objects with an opening for entry into and out of the chamber, and for expulsion of separated larger sized objects out of the chamber. A separating element, which is disposed longitudinally on the interior of the chamber, is passed through the mixture of larger and smaller sized objects to separate the larger sized objects from the smaller sized objects during the rotation of the chamber. As the chamber rotates, the separated larger sized objects, such as soiled litter and animal waste, are transferred from the separating element to a pivotable ramp in the interior of the chamber.

Abstract: A granulator for separating the constituent parts of electrical cable containing relatively light-weight plastic covering relatively heavy electrically-conductive material. The granulator includes a first cutter for cutting the cable into short pieces and a second cutter for cutting the short pieces of cable into a still shorter length sufficient to detach the plastic from the electrically-conductive material to form a mixture of small pieces of plastic and electrically-conductive material. A vibratory sorter separates the mixture of plastic and electrically-conductive material, and includes an elongate, circular and spirally-extending track having a material inlet adjacent a bottom end thereof for receiving the mixture of plastic and electrically-conductive material for separation and a electrically-conductive material discharge slot adjacent a top end thereof for discharging electrically-conductive material.

Abstract: A counterflow single-screw extractor includes a screw conveyor having a helical scroll formed from arcuate flight sections each having a plurality of elongated slots extending away from the direction of screw rotation and permitting the flow of effluent through the product and the flights in a manner controlled by the size, number, and orientation of the slots. The slots permit efficient extraction using relatively little extraction medium and at the same time permit a single-screw extractor to be used without having to periodically reverse the direction of screw rotation to unclog the slots and by the pitch of the screw conveyor. The inventive arrangement permits the use of a multi-section extractor employing different extraction media and/or different extraction media wash rates in different sections of the extractor.

Abstract: The invention relates to a straining apparatus for the separating of solid-liquid mixtures with a downwardly tapering straining basket, the basket inside wall of which has an inclination (.alpha.) increasing from top to bottom, the charging of material to be strained being carried out approximately tangentially at the upper end of the straining basket and the material to be strained flowing downwards helically with radii becoming narrower, the straining basket wall forming at least one helical, inwardly open channel, which is bounded at top and bottom by helical side walls, between which the channel base having straining openings is arranged, the radius of which base decreases from top to bottom and which is inclined with respect to the vertical axis by the angle (.alpha.) in such a way that, in feeding, the inclination is at first small and then increases constantly.
