Abstract: A clamping body freewheel unit and a drive device for motor-assisted driving of an electric bicycle having a clamping body freewheel unit. The clamping body freewheel unit includes a plurality of clamping bodies by which force transmission between an inner shaft and an outer shaft, coupled together via the clamping body freewheel unit, is allowed only in one of two opposite directions of rotation, a cage by which the plurality of clamping bodies of the clamping body freewheel unit are kept together at a defined spacing in a circumferential direction, and a plurality of rolling elements by which the inner and outer shafts are mounted rotatable relative to one another when the inner and outer shafts are coupled together via the clamping body freewheel unit, wherein at least some of the plurality of rolling elements and the clamping bodies are held jointly on the cage.

Abstract: An electric motor for driving a motor vehicle component, in particular a fan motor for chilling cooling water, contains a rotor that includes a commutator, against which a brush rests in a contacting manner. A plastic-sheathed pressed screen for forming a current path that is embossed in an electric insulation is connected to the brush. The current path conducting a motor current is interrupted to form two spaced-apart current path ends. An interruption point is bridged by a contact spring that is used as a temperature fuse and consists of two spring legs, each of which has a fixing end and a free end. Each fixing end of the spring legs is connected to a current path end, while the free ends thereof are in contact with each other using a soldered connection so as to bias the spring.

Abstract: A method and a device controls a rotary tablet forming machine having a rotor. The rotor is capable of being rotated by a drive unit. The rotor includes at least one matrix with allocated upper punches and lower punches and a pressing force, to act on the press mass filled into the at least one matrix is determined. The determined pressing force (PKactual) is compared with a pre-specifiable limit value (PKlimit) and, with a level going below the limit value (PKlimit). Then, required speed (nr) of the rotor can be reduced to a speed below the rated speed (nr-rated).

Abstract: The invention concerns a method and a device for the control of a rotary tablet forming machine (10) where a rotor (12) is capable of being rotated by means of a drive unit (24), the rotor (12) including at least one matrix (14) with allocated upper punches (18) and lower punches (16) and a pressing force (PK), acting on the press mass (26) filled into the one matrix (14) at least, is determined.

Abstract: An air conveyor for a gas-sampling tube that is used for detecting foreign gases or suspended substances in air is described. The air conveyor comprises a body, serving as a handle, that has a control rod which is guided and lockable in a through-duct therein, and which is connected at one end to a bellows that serves as a suction element. The beginning and the end of the suction stroke is uniquely determined by a locking and releasing mechanism connected to the control rod thereby ensuring an exactly reproducible stroke volume. The locking and releasing mechanism utilizes two lever-like linkages, each provided with a hook, which are pivotally disposed in the body one under the other and parallel to the control rod.
