Patent number: 8540931Abstract: An injector insert pipe is arranged in the gas channel of a nozzle for injecting oxygen-containing gas into a pig iron production unit, wherein an interspace which surrounds the pipe is present over the entire pipe length between the wall of the gas channel and the pipe outer wall. The pipe extends at least as far as the nozzle end face which contains the mouth of the gas channel. The pipe space is connected to an oxygen-containing gas feed line, and the interspace is connected to a protective gas supply line. In a process, oxygen-containing gas is fed into the pipe space, which after it has flowed through the pipe, enters the production unit at an entry velocity, and the interspace is simultaneously flowed through by a gas which exits into the production unit at an exit velocity, wherein the entry velocity is greater than the exit velocity.Type: GrantFiled: November 5, 2009Date of Patent: September 24, 2013Assignees: Siemens Vai Metals Technologies GmbH, Siemens AktiengesellschaftInventors: Georg Aichinger, Franz Berner, Stefan Lechner, Marinko Lekic-Ninic, Jan-Friedemann Plaul, Johannes Leopold Schenk, Martin Schmidt, Thomas Söntgen, Bogdan Vuletic, Kurt Wieder, Johann Wurm

Publication number: 20120247966Abstract: A method electrochemically coats a substrate by brush plating. Particles are applied to the surface to be coated via a separated line system before the carrier for the electrolytes. The electrolyte is added to the carrier via a line system. The advantageous result thereof is that an agglomeration of the particles can be prevented because only a short time passes after the application of the particles until the formation of the layer. A device for electrochemical coating has two line systems for the cited purpose. The highly stressed surface components of rollers in rolling mills can be partially coated by the method.Type: ApplicationFiled: August 26, 2010Publication date: October 4, 2012Inventors: Axel Arndt, Jens Dahl Jensen, Ursus Krüger, Stefan Lechner, Marinko Lekic-Ninic, Uwe Pyritz, Manuela Schneider, Heike Springborn, Peter Wieser

Patent number: 5761155Abstract: In a method for determining the position of an object relative to the background with ultrasound, a plurality of ultrasound transducers arranged in a row simultaneously transmit ultrasound in line-shaped fashion in the direction of an object scene and receive both the echo of the signal transmitted by the transducer itself as well as the echoes of the signals generated by the neighboring ultrasound transducers. On the basis of a reference measurement wherein no object is located in the measurement region, the amplitudes and the times of incidence of the echo signals are stored. In the following measurements with an object, the echo amplitudes and the times of incidence of the echo signals are again stored and compared by fuzzy logic to those of the reference measurement. As a result, this supplies the position of the object relative to the background.Type: GrantFiled: August 2, 1996Date of Patent: June 2, 1998Assignee: Siemens AktiengesellschaftInventors: Peter-Christian Eccardt, Nils Kromer, Stefan Lechner, Valentin Magori, Martin Vossiek
