An actuating device () for an automated manual transmission () includes a pressure-medium-operated actuator () having a piston () and a piston rod () connectable to the selector element or shift element of the manual transmission. The piston is arranged in a cylindrical receiving chamber () of the housing () of the actuator and is coaxially movable therein. A sensor system ()includes a magnet () arranged on a holding device () and a magnetic-field-sensitive sensor () is arranged on the housing radially with respect to the magnet ().The holding device has a hollow cylindrical geometry, an anti-rotation element ()is form-lockingly accommodated in an associated recess in the housing (), and that the anti-rotation element extends across the holding device in the manner of a secant such that rotational movement of the holding device is blocked, although axial and rotational movement of the piston are possible.

Actuating device for an automated manual transmission

The present invention relates to a laboratory centrifuge having a cooling device which comprises a compressor enclosed by a compressor housing, with the compressor housing, in the region of the compressor head, being at least regionally provided with a damping material which is capable of absorbing vibrations in the range from 20 Hz to 100 Hz.

Laboratory centrifuge having insulated compressor

The present invention relates to a rotor chamber for a centrifuge, in particular an air-cooled laboratory centrifuge, having a chamber wall, comprising an inner side facing toward the chamber interior, the chamber interior being implemented to receive a centrifuge rotor, and an outer side facing away from the chamber interior, and having a sound barrier which is implemented to reduce the sound emitted from the rotor chamber, which comprises a multilayer damping lining. The first layer comprises a material having essentially sound-absorbing properties relative to the second laver, and the second layer comprises a material having essentially sound-reflecting properties relative to the first layer. The present invention also relates to a centrifuge having such a rotor chamber, and methods for reducing the sound emanating from the rotor chamber of a centrifuge, in particular an air-cooled laboratory centrifuge.
