Abstract: Device for eliminating oversize pellets from balling disks, includes a plow-like tool defined by a series of cylindrical rods that are coplanar and parallel to each other and incorporated into a horizontal plate, whose medial portion incorporates a vertical tubular arm that protrudes vertically and upwards to pass axially through and be selectively and adjustably attached to a vertical sleeve that is incorporated in a distal portion of an extensible arm, which composes a trussed structure that is adjacently attached to a balling disk and protrudes over its area of operation.

Abstract: A raw refuse processing apparatus disk screen separating bed has a series of interdigitated rotatable disk assemblies and is adapted to receive raw refuse at one end, including bagged refuse, and at an intermediate location along its length the separating bed is provided with a bag breaker arrangement comprising a floating carriage having bag delaying disk assemblies and overlying bag ripping disk assemblies of the separating bed.

Abstract: Apparatus for selectively sorting pulp wood chips in accordance with a predetermined maximum thickness includes a plurality of disk members disposed in a plurality of separately rotatable rows, with each row having a plurality of the members disposed in spaced parallel vertical planes, and with members in adjacent rows intermeshing with equal spaces therebetween. Each disk member has a radially contoured outer periphery with the depth of the contour being sufficiently shallow to prevent chips of thickness greater than the predetermined maximum from passing between its outer peripheral edge and an opposing spacer mounted between disk members on an adjacent row. All the rows of disk members are driven in the same direction, but adjacent disks are preferably driven at different peripheral speeds.

Abstract: In a disk screen apparatus of the type having a series of corotating shafts, each of which has a longitudinal series of concentric screen disks which mesh with the screen disks of the adjacent shafts, the screen disks are carried by tubular modules mounted in end-to-end relation on the shafts. Each module comprises a tubular hub having a set of centrally apertured screen disks concentrically mounted in radially extending relation on the hub, which projects through the central apertures of the disks, the disks being attached to the hub in substantially accurately spaced relation to one another axially along the hub. A method is provided for making the modules, and also for making a disk screen apparatus embodying the modules.

Abstract: An improved disc separator in which discs are mounted on retainers to form multiple disc units and the units are mounted end-to-end on a shaft and are clamped in place thereon. The discs have internal splines that project through and beyond splining slots in segments of the retainer, one spline only on each disc being wider than the others and adapted to fit closely in any of the slots in the retainer. The splines project slightly beyond the inner surface of the retainer and are swaged to hold the retainer segments rigidly in fully expanded positions.

Abstract: A process and apparatus for removing straws from bottles employing a plurality of resilient blades which are mounted to rotate such that the ends thereof engage the straws within the bottles removing same.

Abstract: A separator of the type having interleaved rotating discs is constructed with a first shaft having a locating ring welded to the longitudinal midpoint thereof and a second shaft parallel to the first shaft having a feed disc welded to its longitudinal midpoint. Feed discs and intermediate spacers are removably mounted on the shafts with the feed discs on one shaft overlapping and centered between the feed discs on the other shaft. Each feed disc is cut from steel plate, is placed on a splining shaft of a lathe head with one face of the disc in abutment with the ends of three posts defining a plane and a first groove is skin cut in the other face of the disc. The disc is then reversed on the lathe head, and a second groove is skin cut in the opposite face to a depth leaving a predetermined thickness between the groove bottoms whereby the feed discs can be accurately positioned and rotate without interference with one another.
