Patent number: 10451060Abstract: A positive displacement pump for pumping oil in a motor vehicle transmission comprises a pump stage that has a central kidney-shaped suction cavity and two kidney-shaped pressure cavities. Oil is selectively pumped via one kidney-shaped pressure cavity or the other kidney-shaped pressure cavity in accordance with the direction of rotation of the pump stage. This makes it possible to create, with little complexity, two operating stages for the positive displacement pump.Type: GrantFiled: April 27, 2017Date of Patent: October 22, 2019Assignee: Continental Automotive GmbHInventor: Christian Böhm

Publication number: 20190169744Abstract: A substrate treatment apparatus for treating substrates has a plate-shaped substrate carrier and at least one plate-shaped tempering device, which is arranged parallel to the substrate carrier. The substrate carrier has a substrate carrier front side for supporting at least one laminar substrate and a substrate carrier back side, which faces the tempering device. The object of the present invention is to provide a substrate treatment apparatus which enables a heat distribution as evenly as possible in the substrate carrier. For that purpose, there is provided at least one spacer element for forming a distance between the substrate carrier and the tempering device at the substrate carrier back side and/or a surface of the tempering device facing the substrate carrier.Type: ApplicationFiled: August 2, 2016Publication date: June 6, 2019Applicant: Meyer Burger (Germany) GmbHInventors: Sebastian RASCHKE, Erik ANSORGE, Mirko KEHR, Christian BOEHM

Publication number: 20180371966Abstract: A delivery device for a motor vehicle for delivering oil from an oil sump to a lubricating oil circuit of internal combustion engine has, as an oil pump, a double-stroke vane-type pump with positive guidance of vanes. A direct drive of the vane-type pump by means of the internal combustion engine is configured for an operating point P2. An increased or reduced oil demand is compensated by means of an activatable electric drive. A compact oil pump of very small dimensions may thus be used.Type: ApplicationFiled: April 12, 2018Publication date: December 27, 2018Applicant: Continental Automotive GmbHInventor: Christian BOEHM

Publication number: 20180247845Abstract: A substrate carrier includes a substrate carrier plate having a front-sided substrate carrier surface on which at least one substrate receiving area is provided for receiving a respective substrate. The substrate carrier is intended to enable a secure support of the substrate and a simple, damage-free removal of the substrate from the substrate carrier when operating in a fast manner, preferably without impairment of the characteristics of the substrate or the substrate processing. Therefore, the substrate receiving area has an interior area and an exterior area running around the interior area. The exterior area has spaced plateaus which are raised compared to a surface of the interior area for the support of edge areas of the substrates. Ventilation channels are provided between the plateaus.Type: ApplicationFiled: August 2, 2016Publication date: August 30, 2018Inventors: SEBASTIAN RASCHKE, ERIK ANSORGE, MIRKO KEHR, CHRISTIAN BOEHM

Publication number: 20170225167Abstract: The present invention relates to systems and methods for the arrangement of droplets in pre-determined locations. Many applications require the collection of time-resolved data. Examples include the screening of cells based on their growth characteristics or the observation of enzymatic reactions. The present invention provides a tool and related techniques which addresses this need, and which can be used in many other situations. The invention provides, in one aspect, a tool that allows for stable storage and indexing of individual droplets. The invention can interface not only with microfluidic/microscale equipment, but with macroscopic equipment to allow for the easy injection of liquids and extraction of sample droplets, etc.Type: ApplicationFiled: April 25, 2017Publication date: August 10, 2017Inventors: Christian Boehm, Amy Rowat, Sarah Koester, Jeremy Agresti, David A.

Patent number: 9181594Abstract: A process for producing pig iron or liquid primary steel products in a smelting unit (1), in particular a melter gasifier. Iron-ore-containing charge materials, and possibly additions, are at least partially reduced in at least one reduction unit (R1, R2, R3, R4) by means of a reducing gas. A first fraction of the at least partially reduced charge materials is melted down in the smelting unit (1), while carbon carriers and oxygen-containing gas are supplied, with the simultaneous formation of the reducing gas. The reducing gas is fed to the reduction unit (R1, R2, R3, R4) and, after the reducing gas has passed through the reduction unit, it is drawn off as top gas. A second fraction of the at least partially reduced charge materials is fed to a smelting reduction unit for reducing and smelting.Type: GrantFiled: September 25, 2013Date of Patent: November 10, 2015Assignee: SIEMENS VAI METALS TECHNOLOGIES GMBHInventors: Christian Boehm, Jan-Friedemann Plaul, Johannes Leopold Schenk

Publication number: 20140083252Abstract: A gas stream containing both hydrocarbon and hydrogen is separated into a hydrogen-rich fraction and a hydrocarbon-rich fraction. Then at least one sub-quantity of the hydrocarbon-rich fraction is subjected to at least one operation from the group oxidation using technically pure oxygen and reforming using CO2 and H2O. The result is introduced at least as a component of a reduction gas into a reduction unit containing the metal oxides. As a result of the at least one operation, the hydrocarbon content in the reduction gas on entry into the reduction unit is below 12% by volume.Type: ApplicationFiled: May 7, 2012Publication date: March 27, 2014Applicant: SIEMENS VAI METALS TECHNOLOGIES GMBHInventors: Christian Boehm, Robert Millner

Patent number: 8641799Abstract: A process for producing agglomerates from fine-grained iron carriers and at least one binder as a charge material for a metallurgical process is shown. In at least one further agglomeration step, the agglomerates are coated with a layer, comprising iron carriers and at least one binder, and heated in such a way that the binder is cured in the region of the surface of the agglomerates. In a process for producing liquid pig iron or liquid primary steel products from charge materials and possibly additions and agglomerates, the agglomerates are preheated in a reducing zone, which has a preheating stage, in such a way that the agglomerates completely harden in the preheating stage.Type: GrantFiled: August 17, 2009Date of Patent: February 4, 2014Assignee: Siemens Vai Metals Technologies GmbHInventors: Christian Boehm, Hado Heckmann, Hans Herbert Stiasny, Johannes Leopold Schenk
