Patent number: 8402729Abstract: A vehicle for harvesting espalier fruit, such as berries or grapes, and for further processing to a must on the vehicle. The vehicle comprises a frame configured to reach over a row of plants to be harvested in an area of a u-shaped recess of the vehicle. Also included are wheels on both sides of the u-shaped recess and arranged on the frame. Further included is a picking device to separate the fruit from a remainder of the plants. A solid-bowl screw-type centrifuge is arranged directly on the vehicle, which solid-bowl screw-type centrifuge separates and clarifies a fruit mash into at least a solids phase and a liquid phase.Type: GrantFiled: June 15, 2005Date of Patent: March 26, 2013Assignees: Westfalia Separator AG, Ero-Geratebau GmbH, Hochschule WadenswilInventors: Jochen Hamatschek, Frank Schauz, Peter Schöttler, Hans-Joachim Beyer, Dominik Zielke, Michael Erbach, Tilo Hühn

Patent number: 6986733Abstract: A solid bowl helical conveyor centrifuge. The centrifuge includes a rotating drum, having a centrifuge space with a screw that can also rotate. An inlet tube for supplying a material for centrifugation into the centrifuge space, and at least one liquid discharge and at least one solids discharge, wherein the liquid discharge and/or the solid discharge is/are designed as at least one or more openings in a rotating part of the solid bowl helical conveyor centrifuge, in particular through openings in the drum wall. At least one of the openings is covered by a housing which encloses the drum of the solid bowl helical conveyor centrifuge in only some sections, between the at least one housing and the drum and/or other rotating elements of the solid bowl helical conveyor centrifuge (drum heads, hubs) at least one or more gaskets are provided.Type: GrantFiled: April 1, 2004Date of Patent: January 17, 2006Assignee: Westfalia Separator Industry GmbHInventors: Hans-Joachim Beyer, Alfons Monkenbusch, Michael Reichenbach, Michael Müller

Patent number: 6387032Abstract: The invention relates to a screw-type centrifuge configured in such a way that the use of multistage planetary gear trains allows for high peripheral speeds of the drum and large drum diameters. According to the invention the drum bearing on the gear train side is positioned between two stages of the multistage planetary gear train. The housing jacket of the multistage planetary gear train, which is connected to the drum jacket and therefore rotates at the same r.p.m., has an intermediate piece which has a small diameter and is housed by the drum bearing together with a shaft connecting the gear train stages. The system provided for in the invention, according to which the drum bearing on the gear train side is positioned between two stages of the multistage planetary gear train, is used in the case of very large decanters for which the drum rotates at very high peripheral speeds.Type: GrantFiled: August 17, 2000Date of Patent: May 14, 2002Assignee: Westfalia Separator AGInventor: Hans-Joachim Beyer

Patent number: 5551207Abstract: An apparatus for preparing a layered food product has a station for introducing a first food component into a container and a station for introducing a second food component into the container on top of the first food component. The apparatus also has a unit for metering CO.sub.2 snow onto the first food component and a suction unit for removal of residual CO.sub.2 snow before introduction of the second food component into the container, the metering and removal being effected during passage of the first food component in the container through a tunnel in which air conditions about the container may be controlled.Type: GrantFiled: October 31, 1995Date of Patent: September 3, 1996Assignee: Nestec S.A.Inventors: Hans-Joachim Beyer, Hans J.

Patent number: 5386756Abstract: The invention relates to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The chain saw is further equipped with a device for supplying lubricating oil to the saw chain during the movement thereof. The saw chain includes a plurality of cutting links, a plurality of driving links and a plurality of side links all pivotally interconnected by rivets. Abrasive small particles become entrained in the lubricating oil which can lead to premature wear at the pivot locations. The saw chain of the invention includes a hold-back element in front of a rivet to hold back such particles and yet not affect the flow of lubricating oil to the pivot connection.Type: GrantFiled: August 27, 1993Date of Patent: February 7, 1995Assignee: Andreas StihlInventors: Hans P. Stehle, Norbert Apfel, Hans-Joachim Beyer

Patent number: 4956918Abstract: The invention is directed to a guide bar for the saw chain of a motor-driven chain saw and includes a base body section on which a nose assembly section for the saw chain is releasably attached. The nose assembly section is attached to the base body section by means of a releasable lock which is not destroyed in order to effect a separation of the two sections. The lock includes an eccentric cam which is rotatable about an axis transverse to the plane of the guide bar. The cam is in contact engagement with a wall of a bore in the guide bar when the cam is in the locked position.Type: GrantFiled: September 13, 1989Date of Patent: September 18, 1990Assignee: Andreas StihlInventor: Hans-Joachim Beyer
