Publication number: 20130152660Abstract: The invention relates to a thermoforming station in which motors are oriented so as to rotate in the same sense on the drive of the upper table (33) and of the lower table (32) of the thermoforming station whilst actuating elements (31) are oriented in counterrotating manner. In addition, a wobbling table mounting (37) is proposed. Further disclosed is a table-guiding system which is separate from the upper yoke supports. Spring assemblies (46) for holding overload supports are also mentioned. The thermoforming station (26) operates as a whole more reliably and is very easily maintained.Type: ApplicationFiled: April 7, 2011Publication date: June 20, 2013Applicant: KIEFEL GmbHInventor: Wolfgang Frey

Patent number: 8002209Abstract: A fragmentation system including a reaction vessel with processing fluid and fragmentation product and a pair of electrodes. Two respective ends of the pair of electrodes are arranged at a distance to each other inside the reaction vessel and can be admitted with pulsed high-voltage to grind the fragmentation product positioned in a reaction zone. The system also including a solid/fluid separation device, a suspension device to keep the fragmentation product continually suspended in the processing fluid, and a transfer device to transfer processing fluid and a first share of the fragmentation product out of the reaction vessel to the solid/fluid separation device. A second share of the fragmentation product returns to the reaction zone. The system includes at least one return-flow line coupled to the solid/fluid separation device and the reaction vessel to empty the processing fluid from the solid/fluid separation device into the reaction vessel.Type: GrantFiled: July 28, 2004Date of Patent: August 23, 2011Assignee: Forschungszentrum Karlsruhe GmbHInventors: Wolfgang Frey, Ralf Strässner, Andreas Schormann, Kurt Giron, Harald Giese

Publication number: 20080283639Abstract: The invention relates to a method for operating an electrodynamic fragmentation system. The fragmentation product arranged in the process fluid is permanently suspended and forms a suspension with the process fluid. The portion of the processed fragmentation product which attains the target particle size or smaller is discharged from the reaction vessel and the fragmentation product exceeding the target particle size is supplied to the reaction area. The fragmentation system comprises a chargeable electric energy store, a pair of electrodes connected thereto, and both ends thereof are arranged at a distance from each other in the process fluid contained in the reaction vessel. The fragmented product is separated in a solid and liquid manner in a separator in the electrode intermediate chamber until it reaches the target particle size and is smaller than the target particle size and the prepared process fluid is guided back into the reaction vessel.Type: ApplicationFiled: July 28, 2004Publication date: November 20, 2008Applicant: Forschungszentrum Karlsruhe GmbHInventors: Wolfgang Frey, Ralf Strassner, Andreas Schormann, Kurt Giron, Harald Giese
