Patent number: 9730219Abstract: For providing time multiplexing sequences for transmit antennas of a linear or two-dimensional MIMO radar unit that includes antennas situated close to one another (collocated MIMO radar), a method that enables a precise angle estimation includes implementing an algorithm with which a transmit sequence of transmitters and their transmit times are determined so that object movements have essentially no influence on the angle estimation. In this way, as a function of previously known quantities, optimal time multiplexing sequences can be determined in each case.Type: GrantFiled: March 24, 2015Date of Patent: August 8, 2017Assignee: Robert Bosch GmbHInventors: Kilian Rambach, Markus Karl Vogel

Patent number: 6251983Abstract: Inversion carbon blacks and a method for their manufacture are disclosed. The inversion carbon blacks have a lower rolling resistance with identical or improved wet skid behavior. The particle size distribution contains a smaller proportion of particles with large diameters. This leads to an improved abrasion behavior of rubber compounds which were prepared using these carbon blacks. The inversion carbon blacks can be manufactured in conventional carbon black reactors by controlling the combustion in the combustion chamber in such a manner that carbon black nuclei form, which are immediately brought into contact with the carbon black raw material. The carbon blacks present a lower proportion of larger particles if the additions of combustion air and carbon black raw material are increased in an appropriate manner.Type: GrantFiled: June 10, 1999Date of Patent: June 26, 2001Assignee: Degussa - Hüls AktiengesellschaftInventors: Conny Vogler, Karl Vogel, Werner Niedermeier, Burkhard Freund, Paul Messer

Patent number: 6099818Abstract: Disclosed are improved carbon blacks and a process for producing them. The improved carbon blacks are distinguished from conventional blacks having the same CTAB surface, after incorporation into SSBR/BR rubber compositions, by a lower rolling resistance with equal or better wet skid behavior. They can be produced in conventional carbon black reactors by conducting the burning in the combustion chamber so that carbon nuclei form and are immediately brought into contact with the carbon black raw material.Type: GrantFiled: September 25, 1998Date of Patent: August 8, 2000Assignee: Degussa-Huls AktiengesellschaftInventors: Burkhard Freund, Gerhard Kuhner, Ulrich Sattler, Karl Vogel

Patent number: 5651945Abstract: A carbon black reactor having a combustion chamber, a mixing chamber and a reaction chamber positioned along a longitudinal axis of the reactor. The chambers communicate with each other so as to provide a flow path for the hot combustion gases as the combustion gases travel from the combustion chamber, through the mixing chamber and into the reaction chamber. The mixing chamber is designed in the form of an axial narrow area in a dividing wall separating the combustion chamber from the reaction chamber. In addition to the mixing chamber, the combustion chamber and the reaction chamber additionally communicate with each other through at least one bypass bore provided in the dividing wall and positioned radially externally to the mixing chamber and internally to the surface of the combustion chamber. The bypass bores can be either axially aligned so as to be parallel to a central, axial axis of the mixing chamber or inclined.Type: GrantFiled: July 14, 1995Date of Patent: July 29, 1997Assignee: Degussa AktiengesellschaftInventors: Karl Vogel, Reinhold Meuser, Armin Wunderlich

Patent number: 5188806Abstract: A reactor and method for producing carbon black which involves arranging the combustion fuel conduits in a circumferential arrangement within the forward wall of the combustion chamber and providing an impact surface on the opposite side of the combustion chamber. The impact surface forms part of a forward wall of a constricting section which has a tapering passageway with a large opening in fluid communication with the combustion chamber and a smaller opening downstream. A throat passageway or restricting ring is provided at the downstream end of the tapering passageway and the throat passageway opens into an expansion chamber which, in turn, opens into a quenching chamber. Carbon black feedstock is injected into either the tapering passageway, the throat section, or both. The injection of the feedstock is achieved through the use of an axially extending lance and/or one or more radially extending injectors.Type: GrantFiled: June 28, 1991Date of Patent: February 23, 1993Assignee: Degussa AGInventors: Gerhard Kuehner, Karl Vogel, Juan D.

Patent number: 4980106Abstract: The invention concerns a method for dry-pelletizing carbon black, allowing to control pellet quality and increasing the output of any particular pelletizing apparatus. The method calls for pre-compacting the material to be pelletized by means of vacuum before or during pelletizing. The invention also includes two apparatus to carry out the single-stage method version, comprising a pelletizing drum in which are mounted vacuum filter surfaces to pre-compact the powdery initial material in parallel with the on-going prepelletizing procedure. In one apparatus, the inside surface of the drum is a filter surface, in the other apparatus, bundles of stationary filter pipes are provided in the lower drum space.Type: GrantFiled: September 20, 1989Date of Patent: December 25, 1990Assignee: Degussa AktiengesellschaftInventor: Karl Vogel
