Publication number: 20240015418Abstract: In the system, the data, which are acquired in a decentralized manner, are evaluated centrally. Multiple at least temporarily mobile modules are arranged at various positions of a respective underground structure and the temporarily mobile modules are designed to acquire and buffer store measurement data and to transmit acquired measurement data wirelessly and automatically to multiple fully mobile modules as soon as a fully mobile module has reached a distance from a temporarily mobile module at which a wireless data transmission between a respective temporarily mobile module and a fully mobile module is possible. Fully mobile modules are designed to buffer store data that have been received from at least one temporarily mobile module and, upon reaching a data access point that is connected to a central acquisition, evaluation and/or storage unit, to transmit these buffer-stored data to the respective data access point.Type: ApplicationFiled: December 14, 2021Publication date: January 11, 2024Applicant: Technische Universität Bergakademie FreibergInventors: Hans-Günther KRUG, Tobias KRICHLER, Helmut MISCHO

Publication number: 20170292173Abstract: With respect to ceramic filters and filter systems for continuous metal melt filtration, to be able to counter high throughputs of steel melt and also the limitations of filter capacities during continuous casting, an alternative technological approach involves the use of novel, replaceable, and/or rotatable filter bodies at positions in the distributor channel. In some cases, the replaceable and/or rotatable filter bodies may be inserted into the distributor channel for 10 seconds to 30 minutes before being replaced. The filter bodies may be configured as an open-celled foam ceramic or a honeycomb body or a spaghetti filter and serve as a filter geometry of the replaceable and/or rotatable filter bodies in the distributor channel.Type: ApplicationFiled: April 12, 2017Publication date: October 12, 2017Applicants: ThyssenKrupp Steel Europe AG, Technische Universität Bergakademie FreibergInventors: Andreas Baaske, Sven Karrasch, Helmut Schnitzer, Christos Aneziris, Steffen Dudczig, Patrick Gehre, Rüdiger Schwarze

Patent number: 8518134Abstract: The invention relates to a gasification reactor (1) and associated method for the entrained-flow gasification of solid fuels under pressure. The reactor essentially consists of a pressure vessel (4) that can be cooled and an inner jacket (7) that is equipped with a heat shield. At least one crude gas outflow (8) is located at the upper end of the cylindrical pressure vessel and at least one bottoms withdrawal outlet (30) is located at the lower end, the pressure vessel having at least enough space for a moving bed (13), an entrained flow (11) that circulates internally above the surface of the moving bed and a buffer zone (3) situated above said entrained bed.Type: GrantFiled: February 7, 2008Date of Patent: August 27, 2013Assignee: Technische Universität Bergakademie FreibergInventors: Bernd Meyer, Peter Seifert, Steffen Krzack, Sirko Ogriseck, Hardy Rauchfuss, Mathias Rieger, Michael Trompelt, Stefan Guhl
