Patent number: 7373358Abstract: A graphical user interface (GUI) tool for maintaining categorization schemes includes a categorization area that displays user-input fields which may be used to define a number of categories and a number of links that form a categorization scheme. The categorization scheme is organized to enable the computer-executed process to categorize the data. The categorization causes the selection of categories that correspond to the data. The selection is made by making a category determination beginning at the top level and proceeding to the children of categories that correspond to the data.Type: GrantFiled: April 12, 2004Date of Patent: May 13, 2008Assignee: SAP AktiengesellschaftInventors: Christopher Ronnewinkel, Janaki Kumar, Michael Kuehn

Publication number: 20080095642Abstract: A devices for pumping fuel has at least one suction jet pump and a drive line, supplying the suction jet pump with fuel, that branches off from a pressure line leading to an internal combustion engine and that can be blocked off by means of a shutoff valve. By means of a shutoff valve, it is possible to switch off the suction jet pumps. The pressure of the pressure line acts on the shutoff valve in such a way that the shutoff valve closes at a pressure that is greater than or equal to a predetermined closing pressure.Type: ApplicationFiled: October 4, 2005Publication date: April 24, 2008Inventors: Peter Schelhas, Michael Kuehn, Hans Braun, Thomas Wieland, Werner Schneider, Winfried Eckart, Christian Pankiewitz

Patent number: 7251936Abstract: A suspension device is for at least one drive part (10) that is to be cushioned. The drive part can be connected to an accumulator device (12) by a first valve unit (28) and to a tank connection (46) by a second valve unit (34) to transport fluid. The device is provided with a pressure compensation device (50), which when actuated compares the respective prevailing pressures in the drive part (10) and the accumulator device (12) to generate a common pressure level. This comparison permits the pressure level to be rapidly compensated in advance when the actual suspension is enabled in the form of the accumulator device, in such a way that the suspension pressure employed exactly matches the pressure of the respective drive part in the form of a hydraulic or working cylinder that prevails in the later as a result of the preceding load actuation operations.Type: GrantFiled: January 29, 2004Date of Patent: August 7, 2007Assignee: Hydac System GmbHInventors: Michael Kühn, Hubertus Schmidt

Patent number: 7117670Abstract: A control device, in particular for working machines, such as wheel loaders, excavators or similar devices, includes at least one working tool (12), particularly a working shovel that can be actuated by at least one hydraulic working cylinder (10). The device has a control block for controlling the hydraulic fluid paths between the working cylinder (10), a hydraulic fluid supply (P) and a tank (T). The device also has at least one hydraulic accumulator (22) and a shut-off or stop valve (32). The shut-off valve has a controllable valve member (34) and is located between the working cylinder (10) and the accumulator (22). The valve member is connected in the transmission position for connecting the accumulator (22) in order to damp the motion of the working cylinder (10). A selector valve (26) that can be controlled by the control block (20) is connected in the feed line (24), blocking the line (24) in the non-actuated state.Type: GrantFiled: June 27, 2002Date of Patent: October 10, 2006Assignee: Hydac Technology GmbHInventor: Michael Kühn

Patent number: 7100371Abstract: A hydraulic arrangement is provided with at least one pressure accumulator for a hydraulic fluid, a hydraulic cylinder with at least one chamber to which pressure can be applied, a connecting line, on the basis of which the at least one accumulator is connected with the chamber, and a control unit. In order to provide an electronic pipe break safety device, an electronically controlled on-off valve is mounted in the connecting line and coupled for receiving control signals from the control unit, and a signal transmitter, which is coupled for monitoring the pressure in the connecting line is also connected to the control unit. If a pressure drop occurs in the connecting line, a signal change is generated by means of the signal transmitter, whereupon the control unit sends a signal effecting movement of the shut-off valve to its closed position.Type: GrantFiled: September 16, 2004Date of Patent: September 5, 2006Assignee: Deere & CompanyInventors: Marcus Bitter, Heinz Peter Huth, Michael Kühn, Reiner Hoffmann

Patent number: 6968858Abstract: The check valve according to the invention significantly reduces the generation of noise by producing an asymmetrical circulation around the closing body causing a force resulting from the flow and acting on the closing body to have a transverse component in relation to the opening direction, as a result of which increased friction and damping are generated in the closing body guide. The closing body may be asymmetrically embodied, or the housing wall encompassing the closing body may be provided with a conduit extending in the opening direction over at least a part of the travel path of the closing body.Type: GrantFiled: June 2, 2003Date of Patent: November 29, 2005Assignee: Robert Bosch GmbHInventors: Michael Kuehn, Ulrich Mueller

Publication number: 20050228790Abstract: Programs and methods involve structuring categories coherently such that a single categorization scheme may be used to perform multiple business process steps. A method of responding to a received message includes analyzing content of a received message to select which of a plurality of predefined categories relates to the received message. Each predefined category has response information linked to it. If a first of a number of predefined computer-executable response modules is executed, then the first module executes using at least a first part of the response information linked to the selected category. If a second of the number of predefined computer-executable response modules is executed, then the second module executes using at least a second part of the response information linked to the selected category.Type: ApplicationFiled: April 12, 2004Publication date: October 13, 2005Inventors: Christopher Ronnewinkel, Florian Weigmann, Michael Kuehn, Lewis Charnock, Janaki Kumar
