  • Patent number: 11408469
    Abstract: 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.

  • Patent number: 8304231
    Abstract: 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.

  • Publication number: 20090275114
    Abstract: To simplify mixing systems without stirrer systems and to minimize cleaning and validation operations, it is proposed that a vibratory mixer with a vibratory mechanism should have a container. Into this container is inserted a bag which, after use, need not be cleaned and is instead replaced by a new one. This bag is equipped with the connections and sensors required and presterilized. The bag is placed into an angled container. The container serves as a stabilization casing. As a result of the vibration of the container, there is liquid displacement over the angle range, which improves the mixing operation.

  • Publication number: 20080185843
    Abstract: Disclosed is a device for the liquid-proof connection of a soft tube (2) to a connecting piece (4). Said device comprises a connecting piece (4) with a tube joint (6) for attaching the tube (2) as well as a clamping sleeve (8) which is provided with at least two sleeve segments (10) that are distributed along the circumference thereof, protrude from the tube joint (6), and are equipped with a stopping area (30) on the exterior face. A union nut (12) is also provided which cooperates with the stopping area (30) of the sleeve segments (10) by means of an interior stopping area (14) in order to press the same against the tube (2) such that a tight and removable connection is created.
