Patent number: 11408469Abstract: A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.Type: GrantFiled: January 22, 2019Date of Patent: August 9, 2022Assignee: Schaeffler Technologies AG & Co. KGInventors: Fabian Hammerstiel, Christoph Raber, Marc Finkenzeller, Marcel Röll, Florian Vogel, Michael Aschoff

Patent number: 10428299Abstract: A mixing device for mixing contents of a container has a support for supporting the container and a moving device connected to the support for moving the support and mixing the contents of the container. The support has a positioning device to position the container so that a removal side of the container is arranged substantially along a predetermined line of the support. The support is pivotable about a removal pivot axis to move the container into a removal position. The removal pivot axis is at an angle of over 0° to 45° to the predetermined line of the support so that the container can be moved from the mixing position by pivoting the support about the removal pivot axis into the removal position where the removal side is on a lower side of the container and inclined toward a removal region of the container.Type: GrantFiled: May 13, 2015Date of Patent: October 1, 2019Assignee: Sartorius Stedim Biotech GmbHInventors: Marcel Roell, Daniel Hoepli

Patent number: 10363528Abstract: A mixing and thawing device (1) has a rocker drive (2) and a bag holder (3) for holding a bag (7). The bag holder (3) has a base part (8) and a lid part (9) that enclose a holding space (10) for the bag (7). A heating element (11) is arranged in the base part (8). Thus, the holding space (10) is designed as a heat-insulating closed chamber. Interconnected intermediate spaces (14, 15) are arranged between the bag (7) and the base part (8) and between the bag (7) and the lid part (9). One or more flow generators (16) are provided to generate a circulating fluid flow (17).Type: GrantFiled: April 16, 2015Date of Patent: July 30, 2019Assignee: Sartorius Stedim Biotech GmbHInventors: Lars Boettcher, Marcel Roell, Martin Dahlberg, Swen Weitemeier

Patent number: 10253290Abstract: A bioreactor arrangement has a bioreactor and an illuminating body for illuminating a medium in a reactor interior. The illuminating body has at least one emission surface via which light, reflected by at least one end surface into the reactor interior, is emitted. The bioreactor is formed as a container having a transparent wall. The illuminating body is outside the reactor interior, next to at least one subregion of the transparent wall. The illuminating body forms a support surface for the bioreactor with its emission surface. A shaking device has a reactor holder that can be in oscillated, for a bioreactor with a transparent wall. The reactor holder has a two-dimensional illuminating body, the emission surface of which forms a support surface for the bioreactor, via which light can be reflected into the reactor interior of the bioreactor.Type: GrantFiled: April 21, 2011Date of Patent: April 9, 2019Assignee: SARTORIUS STEDIM BIOTECH GMBHInventors: Marcel Roell, Lars Boettcher

Patent number: 8304231Abstract: The invention relates to a bioreactor, comprising a reactor vessel (2) with a housing support (20,20a), extending into the vessel interior (14), with a medium seal against the vessel interior (14) with a transparent sensor piece (34,34a) and an indicator tile (38,38a), arranged in the vessel interior (14), in contact with the vessel contents, which may be scanned by a fiber optic which may itself be introduced into the housing support (20,20a) and connected to a display device (24). In order that the reactor may be embodied as a bag, the housing support (20,20a) is arranged on the upper side of the reactor bag and provided with a flange piece (26) tightly sealed to the vessel wall (28). The flange piece is connected to the sensor piece (34,34a) by means of a preferably tubular connector piece (32,23a), whereby the length of the connector piece is such that the sensor piece (34,34a) permanently reaches into the reactant.Type: GrantFiled: August 10, 2005Date of Patent: November 6, 2012Assignee: Sartorius Stedim Switzerland AGInventor: Marcel Röll
