Patent number: 9431878Abstract: An electric machine has a base body with a stator, a rotor shaft mounted in the base body, and a heat exchanger. Cooling ducts for a liquid cooling medium are arranged in the base body. The rotor shaft is embodied as a hollow shaft through which the liquid cooling medium can flow. The heat exchanger dissipates heat contained in the liquid cooling medium to the surroundings of the electric machine. The heat exchanger, the rotor shaft and the cooling ducts are fluidically connected in series, producing a closed circuit for the liquid medium. A feed element is arranged to co-rotate with the rotor shaft. The feed element is inserted in the closed circuit for the liquid cooling medium to forcibly circulate the liquid cooling medium in the closed circuit as the rotor shaft for the liquid cooling medium rotates.Type: GrantFiled: December 13, 2011Date of Patent: August 30, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Konrad Brandl, Vladimir Danov, Klaus Dennerlein, Bernd Gromoll, Jürgen Hofmann, Patryk Piotrowski, Andreas Schröter

Patent number: 8417953Abstract: A method and system for restricted service access is described. To access adult content, the user has to enter an administrator personal identification number into a mobile device. Upon receipt of the administrator personal identification number, an access code is generated, which is provided to a content provider. The content provider can calculate a valid time window and/or request an acknowledge message from a central server. If the current usage is within the valid time window or otherwise verified, access to the content is allowed. Thus, children are prevented from accessing adult content, while adult access is permitted.Type: GrantFiled: December 8, 2005Date of Patent: April 9, 2013Assignee: Koninklijke KPN N.V.Inventor: Andreas Schröter

Publication number: 20130085687Abstract: A method and a device for determining the flow rate of magnetic or ferromagnetic particles in a suspension that flows through control chambers are provided. The magnetic flux F1 is measured as a function of time t using a measuring coil that surrounds a first control chamber, the magnetic flux representing a measurement, at a particular time, of the quantity of magnetic particles contained in the suspension. In a second control chamber, at a predetermined distance d from the first control chamber, the magnetic flux F2 is measured as a function of time t using a second measuring coil that surrounds the second control chamber and the measurements F1 (t) and F2 (t) are compared to produce a temporal distance ?t which is used together with the predetermined distance d to calculate the flow rate. The method and device can be used, for example, in an ore mining installation.Type: ApplicationFiled: April 11, 2011Publication date: April 4, 2013Inventors: Vladimir Danov, Helmut Eckert, Werner Hartmann, Manfred Rührig, Andreas Schröter, Roland Weiss
