Patent number: 10682796Abstract: An additive manufacturing system includes a slip clutch coupled to an actuator of a mechanical driver that feeds solid extrusion material into a heater for supplying thermoplastic material to a manifold in an extruder head. A speed of the actuator can be set to enable the actuator to operate at a rotational speed that is slightly greater than the rotational speed of the mechanical mover. This configuration enables the pressure of the thermoplastic material in the manifold of the extruder head to be in a predetermined range no matter how many nozzles are opened in the extruder head.Type: GrantFiled: October 26, 2016Date of Patent: June 16, 2020Assignee: Xerox CorporationInventors: Barry P.

Patent number: 6070522Abstract: A transportable apparatus includes a housing with a door which opens to facilitate placement of trash within a trash receiving chamber of the apparatus. A sweep within the trash receiving chamber is actuated upon closing the door, forcing the deposited trash into a first compaction chamber, wherein the trash is mixed and compressed into a condensed mass by converging chamber walls and a downwardly directed spray of water released from high pressure nozzles at the top of the chamber. A reciprocating horizontal plate at the lower end of the first compaction chamber slices off a bottom layer of the mass of trash with each cycle of forward and rearward movement. The sliced layers of trash are pushed and compacted into a second compaction chamber until the second chamber is full. The trash is then compressed to form a composite unit of predetermined size and configuration.Type: GrantFiled: February 16, 1999Date of Patent: June 6, 2000Inventor: Reino Koljonen

Patent number: 4451322Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers.Type: GrantFiled: April 23, 1982Date of Patent: May 29, 1984Assignees: Richard A. Moerman, Barry SullivanInventor: Bolek Dvorak

Patent number: 4256033Abstract: A method is provided for splitting and extracting green plants, such as lucern, for fodder and preserving of the pulp. The method provides for separatelygathering the juice and the pump with various percentages and at a desired rate for more judicious utilization of those components and in particular, a better valorization of proteins; and forpreserving the pump in commercial fractions by a method of batch-compaction and of anaerobic storage, eliminating all dehydrations and thus exhibiting an appreciable savings of energy.The method is characterized in that it includes a primary phase of crushing and breaking of stems without mixing of the cellulose and a secondary phase in which one realizes a definitive splitting to the desired degree. A device for using the method is also disclosed. The method and device have application in the agro-alimentary industries.Type: GrantFiled: June 26, 1979Date of Patent: March 17, 1981Inventor: Milenko Poznanovic

Patent number: 4253390Abstract: A system for extracting liquids from fruit, vegetables, or other similar materials with particular application to dejuicing grapes. The system provides a destemmer for receiving picked grapes and for removing stems and leaves therefrom. The destemmer partially crushes the grapes during the destemming operation producing free run juice in the resulting grape must. The must is transferred to a predrainer screw press which separates and collects the free run juice and a preselected portion of the residual juice by means of a gentle pressing action augmented by centrifugal force. The partially dewatered must is then transferred to one or more final screw presses which apply heavy compression to extract the remainder of usable juice from the predrained must. The predrainer press and final presses have throughput control means to provide a continuous feed of grapes through the system for maximum efficiency of juice extraction.Type: GrantFiled: October 22, 1979Date of Patent: March 3, 1981Inventors: Arthur J. Hunt, Arthur J. Hunt, Jr.
