Patent number: 4974781Abstract: This invention relates to an improved method and apparatus to effect the separation of component fractions from paper-containing and plastic-containing waste materials. This method and apparatus accepts materials of widely varying characteristics such as paper, plastics, glass, metal, food wastes and other materials to be inserted en masse into a rotating vessel equipped with lifting paddles and directional flighting. In this way the intimate contact of materials with moisture and heat is accomplished, thus effecting the repulping of paper materials. The repulped materials, as a result of directional tumbling, are dispersed throughout the vessel. Because of the repulping of the pulpable materials, size reduction of the randomly large and odd-shaped pulpable material is accomplished. By virtue of the size reduction of the large and odd-shaped pulpable materials, the non-pulpable components are freed of the particle shapes and surfaces that affect separation.Type: GrantFiled: March 9, 1989Date of Patent: December 4, 1990Assignee: The Placzek Family TrustInventor: Terrance M.

The method comprises the steps of operating said apparatus at a first magnetic field intensity level slightly greater than the minimum intensity level required to generate random motion of said working pieces, and then periodically either increasing or decreasing the intensity level from said first intensity level to maintain random motion of said working pieces. Similarly, the apparatus comprises a timing mechanism which periodically either increases or decreases the intensity level from said first intensity level.Type: GrantFiled: October 26, 1982Date of Patent: December 30, 1986Assignee: Fuji Electric Co., Ltd.Inventors: Yasuo Watanabe, Mitsuhiro Nakamura

Patent number: 4616786Abstract: Surplus concrete or return concrete to be processed is poured into a high-capacity receiving bin and is transferred at a metered rate from said bin by means of a screw conveyor to a washing apparatus, in which fine components are separated from very fine components. The transfer at the metered rate is effected in dependence on the driving power of rotary motors of the rotary washing apparatus. When the driving power of the motors exceeds a predetermined value, then the motor of the screw conveyor is deenergized. When the driving power decreases below that value or below another value, the supply at the metered rate is resumed. The plant operates fully automatically and when the receiving bin has been emptied the plant is automatically cleaned and automatically shut down.Type: GrantFiled: August 13, 1984Date of Patent: October 14, 1986Assignee: Stetter GmbHInventor: Rudolf Riker

Patent number: 4616785Abstract: Wood chips are debarked by compacting them in a mass, and agitating the compacted mass. In the compacted mass the chips are caused to rub against one another so that the bark is removed from the chips by rubbing friction of chip against chip. Frictional pressure on the removed bark finely comminutes the bark for easy separation from the debarked chips. The compacting and agitating of the chip mass is effected by a rotor device in a debarking drum chamber.Type: GrantFiled: July 30, 1982Date of Patent: October 14, 1986Assignee: Beloit CorporationInventor: Adrian Artiano

Patent number: 4601431Abstract: An improved traveling magnetic field-type apparatus for crushing, mixing, polishing, deburring and the like is provided, comprising a container containing working substances and a quantity of material to be crushed operatively arranged between first and second traveling magnetic field generators. The generators are selectively shiftable between a first orientation and a second orientation, in which like polarity and dissimilar polarities face each other across the container. The field generators may be circular and concentrically arranged, or in the shape of a circular arc. Diaphragms also may be provided in the container to distribute more uniformly the working substances and the material to be crushed. It has been determined that the working substances are more readily magnetized, resulting in a higher magnetic torque, if they are relatively longer in the axial direction than in the cross sectional direction.Type: GrantFiled: September 13, 1982Date of Patent: July 22, 1986Assignee: Fuji Electric Company, Ltd.Inventors: Yasuo Watanabe, Takeo Takahashi, Keiji Haga

Patent number: 4582263Abstract: A drum granulator is described in which at least a part of the cylindrical outer wall is resilient. This can be achieved, for example, by forming the drum from steel and fitting it with a resilient rubber lining, which is exposed in way of circumferentially extending slots in the steel. The drum rotates past pivotted rollers which are allowed to descend abruptly onto the resilient part of the wall, dislodging any material which adhered to it.Type: GrantFiled: November 30, 1983Date of Patent: April 15, 1986Assignee: Lever Brothers CompanyInventor: Francois Delwel

Patent number: 4582268Abstract: Apparatus for treating a granular substance, especially for milling nuclear reactor fuel in powder form having a treatment drum supported rotatably about a central axis, an associated drive unit to drive the treatment drum about this central axis, and a cover at one end. The cover has two cover sections which are arranged side by side in the direction of the central axis of the treatment drum and can be rotated relative to each other about the central axis between two stops by means of a cover drive unit. The outer cover section has an opening for docking a substance container and the inner cover section has a passage opening which is aligned at one of the two stops with the opening for docking and which is closed at the other stop by the outer cover section. The treatment drum can be tilted about a tilting axis perpendicular to its central axis by means of a tilting unit.Type: GrantFiled: August 9, 1983Date of Patent: April 15, 1986Assignee: Alkem GmbHInventor: Manfred Adelmann

Patent number: 4571963Abstract: A material treatment apparatus having a bowl or container for the material to be treated. The bowl is suspended by resilient means, and a vertical reciprocating motion is applied to the bowl, the resilient means during the vertical motion imparting a rotary oscillation to the bowl or container.Type: GrantFiled: July 26, 1984Date of Patent: February 25, 1986Inventor: Cyril J. Williams

Patent number: 4562970Abstract: A closure member (11) for opening and closing an outlet orifice (30) in a stationary cover (32) of a drum (1) drivable in rotation in a processing machine, in which the material being treated is conveyed upwards towards the outlet aperture, which is provided generally at the lower region of the drum. Closure member (11) is movably fitted to the cover (32) and is at least partly closable.Type: GrantFiled: January 20, 1984Date of Patent: January 7, 1986Inventors: Walter Eirich, Paul Eirich, Hubert Eirich

Patent number: 4561598Abstract: A vibratory apparatus is disclosed for scrubbing, abrading, pulverizing, grinding, crushing, milling and/or separating granular material. The apparatus includes a two mass vibratory system with a tube, as part of the working mass, provided for the granular material and having an inlet end and an outlet end open to a stack at a location lower than the inlet end. The stack has means for creating an upward countercurrent air flow therethrough. A driving mass, including a vibration generating assembly, is provided for vibrating the driving mass and the working mass so that the granular material is agitated in the tube at large accelerations to scrub, abrade, pulverize, grind, crush or mill the granular material. When the apparatus is used as a separator or classifier, the countercurrent air flow in the stack causes minute particles to move up through the stack to separate the minute particles from the batch of granular material as the material is discharged into the stack.Type: GrantFiled: December 12, 1983Date of Patent: December 31, 1985Assignee: General Kinematics CorporationInventor: Albert Musschoot
