Patent number: 7983788Abstract: A method allows analyzing and describing the reflective properties of a three-dimensionally structured original surface. The topology of the original surface is determined and the topological data are stored in the form of a depth map in a first data record and evaluated with respect to the influence of the data on the reflective properties. Each surface element is assigned a reflective value in accordance with the evaluation and the value is stored in a second data record and made available to other machining or inspection systems. There, the reflection values of the second data record are divided into classes and the depth values of the first data record, assigned to the classified reflection values, are varied in accordance with the classification. Finally, the changed depth values are employed as parameters for electronically controlling a tool in order to machine the artificially produced surface.Type: GrantFiled: December 19, 2008Date of Patent: July 19, 2011Assignee: Benecke-Kaliko AGInventors: Oliver Stahlhut, Christian Neumann, Michael Mäker

Patent number: 7938349Abstract: The invention relates to a roll mill having a grinding plate and at least one grinding roll rolling on the grinding plate, wherein material which is to be comminuted, after being subjected to loading in a gap formed between the grinding plate and grinding roll, is directed away over the periphery of the grinding plate and, furthermore, a stationary accumulating edge, which does not rotate along with the grinding plate, is provided, at least on that side of the grinding roll which is directed towards the periphery of the grinding plate, this accumulating edge forming at least part of an elevation of the periphery of the grinding plate. The elevation of the periphery of the grinding plate here is higher in the region of the grinding rolls than in the region between the grinding rolls, in order to prevent the material which is to be comminuted from escaping radially from the gap formed between the grinding plate and grinding roll.Type: GrantFiled: June 20, 2007Date of Patent: May 10, 2011Assignee: Polysius AGInventors: Christian Neumann, Franz-Josef Zurhove

Publication number: 20090157215Abstract: A method for producing three-dimensionally structured surfaces of objects, the object surface being created as a reproduction of a three-dimensionally structured original surface with the aid of a machining tool. Accordingly, the topology of the original surface is first determined, a measured depth value being assigned to each surface or grid element, creating a depth map of the original surface. The depth values are evaluated in terms of their influence on the reflective properties of the surface elements and the reflective properties are stored in the form of parameters. The depth values are then modified in accordance with the reflective values and are used as topological data for the electronic control of a machining tool.Type: ApplicationFiled: December 22, 2008Publication date: June 18, 2009Applicant: Benecke-Kaliko AGInventors: OLIVER STAHLHUT, CHRISTIAN NEUMANN, MICHAEL MAKER

Patent number: 6969998Abstract: The present invention relates to a measuring device and a method for contactless detection of an angle of rotation or a torsional rotation. The measuring device includes a first resonator (2) and a second resonator (4). The two resonators (2, 4) have an essentially circular circumference, on which at least one protrusion and/or one recess is disposed. The two resonators (2, 4) are coplanar to one another and are also rotatable relative to one another. In addition, an exciter device (6) for exciting the resonators and a receiver device (6) for measuring a backscattered signal are present. Upon a relative rotation of the two resonators (2, 4) to one another, the resonant frequency changes, which is used as a measure for ascertaining the angle of rotation.Type: GrantFiled: July 25, 2001Date of Patent: November 29, 2005Assignee: Robert Bosch GmbHInventors: Christian Neumann, Ralf Schmidt

Patent number: 6339329Abstract: A method for manufacturing a GMR bridge detector as well as the bridge detector itself in which magnetoresistive resistors are interconnected in the form of a bridge to detect a magnetic field. The resistors consist of a material that exhibits the giant magnetoresistive ratio (GMR) effect. The magnetoresistive sensitivity of the individual resistors is produced through annealing. The annealing of the resistors takes place through selective feeding of a current that is sufficient for reaching the temperature required for annealing into the bridge connections. Depending on the wiring of the bridge connections, the resistors are provided with the property necessary for the GMR effect either singly or in pairs. As the material for the resistors, in particular, a material of the class of discontinuous multilayer materials, particularly NiFe/Ag, is used in which the GMR property is produced through single annealing at a specific temperature.Type: GrantFiled: April 29, 1999Date of Patent: January 15, 2002Assignee: Robert Bosch GmbHInventors: Christian Neumann, Klaus Marx, Franz Jost, Martin Freitag, Dietmar Senghaas

Patent number: 5912472Abstract: A portion of the superconductor in a planar resonator made from that superconductor can be switched into the normally conducting state so that its effective lateral dimensions are changed. The special advantage of this planar resonator is that a switchable filter can be constructed very economically based on its planar resonator structure. Since no perturbing bodies are necessary in the field, the invention points the way to a switchable filter with reduced high frequency losses.Type: GrantFiled: May 15, 1997Date of Patent: June 15, 1999Assignee: Robert Bosch GmbHInventors: Klaus Voigtlaender, Claus Schmidt, Matthias Klauda, Christian Neumann
