Patent number: 9174255Abstract: In a rolling mill train (2; 30; 56) for processing rolling stock (4, 32), at least three rolling stands (10) are directly adjacent in the rolling direction and are driven by electric motors (20) having superconducting windings. It is thereby possible to keep the distances between the rolling stands smaller than with conventional electric drives, thus reducing energy losses during the rolling process. A combined casting and rolling station (40), which is equipped with such an electric motor (20) in the rolling stands, is configured and/or operated efficiently in terms of the required heating power.Type: GrantFiled: May 31, 2010Date of Patent: November 3, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Michael Diez, Norbert Moritz, Günther Winter

Patent number: 8991612Abstract: A method obtains non-magnetic ores from a suspension containing ore particle-magnetic particle agglomerates. The method involves dividing ore particle-magnetic particle agglomerates precipitated from the suspension into a mixture of separately present ore particles and magnet particles, separating the magnetic particles from the mixture, forming a first mass flow containing magnetic particles and a second mass flow containing ore particles. At least one information describing a measure of the content of ore particles in the first mass flow and being associated with the first mass flow and/or at least one information describing a measure of the portion of magnetic particles in the second mass flow and being associated with the second mass flow are determined in order to determine the efficiency of at least one of the separation processes described above.Type: GrantFiled: May 31, 2012Date of Patent: March 31, 2015Assignee: Siemens AktiengesellschaftInventors: Michael Diez, Argun Gökpekin, Wolfgang Krieglstein

Patent number: 8991615Abstract: A method obtains non-magnetic ores from a suspension-like mass flow containing non-magnetic ore particles. The method involves mixing the mass flow with magnetic particles in a mixing device and forming ore particle-magnetic particle agglomerates, feeding the mass flow as a separator feed flow to a magnetic separator for separating the ore particle-magnetic particle agglomerates from the mass flow, forming a separator concentrate flow containing ore particle-magnetic particle agglomerates and a separator residual flow containing the remaining constituents of the mass flow, and separating the ore particles from the ore particle-magnetic particle agglomerates contained in the separator concentrate flow.Type: GrantFiled: May 31, 2012Date of Patent: March 31, 2015Assignee: Siemens AktiengesellschaftInventors: Michael Diez, Argun Gökpekin, Wolfgang Krieglstein

Publication number: 20140124450Abstract: A first substance is separated from a flowable primary substance flow by mixing and precipitation in a separating device. The mixing binds the first substance and at least one magnetic carrier particle to each other. In the precipitation, the carrier particles contained in the primary substance flow, including the bound first substance, are separated by magnetic forces into a residual primary substance flow depleted of the first substance and a secondary substance flow enriched with the first substance. By varying a parameter which influences the magnetic forces in a predetermined manner during the precipitation, the content of the first substance in the secondary substance flow and/or in the residual primary substance flow is influenced. Based on the change of the content of the first substance caused by the variation due to the predetermined variation, at least one parameter of the separation method is set.Type: ApplicationFiled: May 31, 2012Publication date: May 8, 2014Applicant: SIEMENS AKTIENGESELLSCHAFTInventor: Michael Diez

Patent number: 8521252Abstract: The invention relates to a method for displaying a hollow space in an object under investigation, wherein the hollow space has an access point and a target point for a surgical instrument which can be introduced at least partially into the hollow space, and wherein a three dimensional image data set of a section of the hollow space having the access point and/or the target point is determined and spatially displayed. By highlighting the access point and/or the target point in the spatial display of the hollow space section it is possible to make a method available which provides the surgical staff with improved guidance in the object under investigation.Type: GrantFiled: January 4, 2007Date of Patent: August 27, 2013Assignee: Siemens AktiengesellschaftInventor: Michael Diez

Patent number: 8342336Abstract: In a device and a method for extracting non-magnetic ores from a pulp comprising non-magnetic ore particles and having a solid fraction of at least 30 mass percent, the pulp flows continuously through a reactor in the direction of flow and magnetic or magnetizable magnet particles that form ore magnetic particle agglomerations with the non-magnetic ore particles are added to said pulp. The ore magnetic particle agglomerations are moved by a magnetic field into an accumulation range of the reactor, and are then discharged out of reactor range and separated into ore and magnetic particles. In a device and a method, the separated magnetic particles are treated, in particular hydrophobized, such that during a new interaction with non-magnetic ore particles, new ore magnetic particle agglomerations are formed. Accordingly, a high yield of ores can be obtained and the mine can be operated in an economical and environmentally friendly manner.Type: GrantFiled: February 10, 2009Date of Patent: January 1, 2013Assignee: Siemens AktiengesellschaftInventors: Michael Diez, Imme Domke, Werner Hartmann, Hartmut Hibst, Wolfgang Krieglstein, Alexej Michailovski, Norbert Mronga, Michael Riebensahm, Wolfgang Schmidt, Thomas Servay
