Patent number: 10227278Abstract: The production of 2-propylheptanol described here is effected via Rh-catalyzed hydroformylation of C4-olefin to afford C5-aldehyde, aldol condensation to afford the C10-aldehyde and hydrogenation to afford the C10-alcohol. The emphasis is on the hydroformylation and the ligand employed therein. The problem addressed by the invention is that of reducing the costs of 2PH production. This problem is solved when a cheaper catalyst system which simultaneously achieves a better regioselectivity is employed in the hydroformylation.Type: GrantFiled: August 2, 2016Date of Patent: March 12, 2019Assignee: EVONIK DEGUSSA GmbHInventors: Katrin Marie Dyballa, Robert Franke, Dirk Fridag, Markus Schwarz, Hermann-Josef Schulte-Althoff, Frank Geilen

Patent number: 8920315Abstract: A quick-action tensioning clip of a wound retractor, with at least one braceable seat for at least one holding arm and/or for a joint ball of a holding arm, is made available which can be operated safely, easily and quickly and which requires only low operating forces and at the same time safely and permanently generates high clamping forces, this being achieved by the fact that, in order to generate the tensioning force, it is equipped with a toggle catch composed of two joint levers which are connected to each other via a connecting joint and which, at their free ends, are articulated via attachment joints on component parts of the quick-action tensioning clip that can be mechanically moved away from or towards one another.Type: GrantFiled: December 22, 2009Date of Patent: December 30, 2014Assignee: Condor GmbH MedicaltechnikInventor: Hermann-Josef Schulte

Patent number: 8579808Abstract: A tensioning device of a surgical retractor has a tensioning section for applying a tensile force to a tool that is to be arranged thereon, and a holding bar fixed in position relative to the tensioning section, and also a locking device. The locking device is provided between the holding bar and the tensioning section and has a releasable locking function counter to the direction of the tensile force. The tensioning device can be operated comfortably, with minimal force being applied, is optimally accessible and takes up only a small overall volume. This is made possible by the fact that the locking device is configured as a linear ratchet or linear feed mechanism and that the feed mechanism has an actuating lever and an unlocking device.Type: GrantFiled: March 18, 2011Date of Patent: November 12, 2013Assignee: Condor GmbH MedicaltechnikInventor: Hermann-Josef Schulte

Patent number: 7249456Abstract: A method of controlling the energization of a heating device for the regeneration of a particle filter disposed in the exhaust duct of an internal combustion engine, particularly a Diesel engine, wherein a measure for the soot charge state of the particle filter the exhaust gas back pressure is determined while the engine is preferably idling, the exhaust gas recirculation is switched off, and predetermined conditions are present in the exhaust gas duct upstream of the particle filter, and then an exhaust gas back pressure signal is compared with a threshold value indicating a soot charge sufficient for the initiation of a regeneration of the particle filter and the heating device is enabled for the initiation of the regeneration procedure if the exhaust gas back pressure signal is greater than the threshold value.Type: GrantFiled: June 21, 2005Date of Patent: July 31, 2007Assignee: HJS Fahrzeugtechnik GmbH & Co.
