Publication number: 20170218295Abstract: The present invention relates to the use of hydraulic fluids in plastic injection molding processes. Thereby it was surprisingly found that the use of hydraulic fluids with the right combination of physical parameters like the viscosity grade, the viscosity index, the density and the dispersancy allows for significant energy savings in plastic injection molding processes (PIM). The PIM process is an industrial process to manufacture plastic parts at well controlled temperatures, pressures and cycle times. The energy consumption of the process became more important over the last years, however, other parameters like process stability and accuracy of plastic part parameters as well as machine protection and long oil drain intervals have to be satisfying.Type: ApplicationFiled: August 7, 2015Publication date: August 3, 2017Applicant: Evonik Oil Additives GmbHInventors: Frank Lauterwasser, Frank-Olaf Mähling, Robert Kolb, Thorsten Bartels, Thomas Schimmel, Stefan Maier, Michael Alibert

Patent number: 8780351Abstract: A method for detecting the presence of molecules includes bringing into contact with at least one optical grating comprised of a first liquid phase, a second liquid phase which cannot be mixed with the first liquid phase. The first liquid phase is arranged on a substrate in a form of periodic structures having a periodicity ranging from about 190 nm to about 10 ?m. The molecules to be detected, which are capable of changing the optical characteristics of the at least one optical grating are added to the first liquid phase or to the second liquid phase either before, during or after the bringing step. The presence of molecules is detected by measuring a changed reflection or transmission of light at the at least one optical grating or a changing spatial course of the diffraction pattern as soon as the first liquid phase makes contact with the second liquid phase and with the molecules to be detected.Type: GrantFiled: April 24, 2010Date of Patent: July 15, 2014Assignee: Karlsruher Institut fuer TechnologieInventors: Stefan Walheim, Thomas Schimmel, Steven Lenhert, Harald Fuchs, Falko Brinkmann, Thomas Laue

Publication number: 20120211368Abstract: The invention relates to a method for producing a switch element. The invention is characterized in that the switch element comprises three electrodes that are located in an electrolyte, two of which (source electrode and drain electrode) are interconnected by a bridge consisting of one or more atoms that can be reversibly opened and closed. The opening and closing of said contact between the source and drain electrodes can be controlled by the potential that is applied to the third electrode (gate electrode). The switch element is produced by the repeated application of potential cycles between the gate electrode and the source or drain electrode. The potential is increased and reduced during the potential cycles until the conductance between the source and drain electrode can be switched back and forth between two conductances, as a result of said change in potential in the gate electrode, as a reproducible function of the voltage of the gate electrode.Type: ApplicationFiled: February 16, 2012Publication date: August 23, 2012Inventors: Thomas Schimmel, Fangqing Xie, Christian Obermair
