Publication number: 20110177258Abstract: A method and device disclose how to drain a liquid coating metal from the two sides of a running steel strip. The method transfers a strip coated with a liquid coating metal, as it runs at the tank outlet, from a region not subjected to a magnetic field to another region subjected to a static magnetic field generated between the poles of magnetic members arranged opposite each other on either side of the strip and having field lines, or at least a main shell of the field lines, intersecting with the strip over at least one minimum longitudinal extent so that the liquid coating metal is correlatively subjected to a magnetic field variation generating on the liquid metal a force opposite to the running direction. Due to the low field variation, this magnetic braking effect generates little Foucault current in the strip.Type: ApplicationFiled: September 23, 2008Publication date: July 21, 2011Applicants: SIEMENS VAI METALS TECHNOLOGIES SAS, L'INSTITUT POLYTECHNIQUE DE GRENOBLEInventors: Roland Ernst, Yves Fautrelle, Benjamin Grenier, Jean-Jacques Hardy

Patent number: 7443145Abstract: A switching regulator for generating a regulated output voltage comprises a charging switch, a network with a coil, a capacitor and a diode as well as a control to open and close the charging switch. On the output side, the network has a positive output rail and a negative output rail, wherein the output voltage to be regulated is applied between the positive output rail and the negative output rail. The control is formed to control a change-over switch to connect the control input of the charging switch either to the positive output rail or the negative output rail via a potential coupling means. Thus, for controlling the switch, no individual potential has to be generated, but the potential at the positive output rail or the negative output rail, which is anyway applied, is used for controlling the charging switch. Thereby, the inventive switching regulator can be structured in a simple way and, additionally, provides defined and fast startup without requiring additional startup circuits.Type: GrantFiled: February 27, 2006Date of Patent: October 28, 2008Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Michael Hackner, Roland Ernst, Hans-Peter Hohe

Patent number: 7138790Abstract: A control device for controlling a charging switch in a switching regulator with an inductance, a filter capacitance and a diode comprises a clock generator for providing an operating clock, an output voltage detection means and an inductance current detection means, as well as a comparator for comparing the detection signals generated by the two detection means. The charging switch is switched on by an event in the clock and switched off when the comparator determines a predetermined relation between the two detection signals. The voltage detection signal is formed to have an inverted curve in relation to the detected output voltage, such that when the output voltage to be detected increases the detection signal falls and vice versa. Thus, a stable and simple regulation of the output voltage across a current locked loop is possible, where no filtering of an actual value has to be performed. Thus, a stable current locked loop with simple structure is obtained in a wide range.Type: GrantFiled: February 27, 2006Date of Patent: November 21, 2006Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V.Inventors: Michael Hackner, Roland Ernst, Hans-Peter Hohe

Publication number: 20050086535Abstract: Method for authenticating a user for the purposes of establishing a connection from a mobile terminal to a WLAN network A user in a telecommunications network wishes do use a WLAN access. To do this he needs a WLAN authentication token, a login and a password. The key point of the invention is that, for the transmission and communication of the authentication data to the WLAN, it is not the SMS protocol which is used but the alternative USSD (Unstructured Supplementary Service Data) protocol. These so-called USSD strings can be easily entered by users on their terminal keypads. The USSD string is then not sent to the SMS gateway, as in the known method, but is sent directly to the Home Location Register (HLR) of the mobile radio network.Type: ApplicationFiled: August 12, 2004Publication date: April 21, 2005Applicant: Siemens AktiengesellschaftInventors: Roland Ernst, Petra Kastl, Manfred Leitgeb, Hagen Scheibe

Patent number: 5280496Abstract: An induction furnace includes a crucible having a plurality of cooled metallic segments (6A, 6B) electrically insulated from each other and an electromagnetic induction coil (5) arranged around the crucible, wherein the electromagnetic induction coil is energized with low frequency electric current. Each of the metallic segments forming the crucible wall is made of a relatively thin sheet, and a cooling pipe is provided on each segment.
