Abstract: A device for applying active substances to surfaces of medical implants (11) has a base station (22) and a replaceable cartridge (10) that can be mounted on the base station, the cartridge (10) having a holder for the implants (11) and also a nozzle for spraying the active substance onto the surface. The base station (22) has a drive unit (75) for moving the holder and the nozzle in relation to each other. For this purpose, the cartridge (10) has a basically cylindrical first housing part (14) which has the holder and a basically cylindrical second housing part (15) which has the nozzle. The first and second housing parts (14, 15) are formed so that they fit into each other and are arranged so that they can be moved, and preferably rotated, relative to each other (FIG. 8).

Abstract: A drive device for a wiper arm of a windscreen-wiper assembly is equipped with a linkage system in a drive train between the wiper arm and a screen-wiper motor. The linkage system comprises at least two intersecting pivot arms, both of which are flexibly connected at one end to a rocker carrying the wiper arm, and one of which is pivot-mounted at its other end on a vehicle-mounted bearing element, and the other is fastened at its other end to a reversibly operable shaft.

Abstract: A device for applying active substances onto surfaces of medical implants, in particular stents, consists of a base station, and of an exchangeable cartridge which can be mounted on the latter. Provided on the cartridge there is a holder for the stents, and a nozzle for spraying the active substance onto the surface of the stent. Provided on the base station there is a drive unit via which the holder and the nozzle are moved relative to one another.

Abstract: A drive device includes an electric drive motor, a housing, at least one shaft driven by the drive motor, compensation elements enabling the end play of the shaft to be adjusted or compensated while the shaft is being mounted, and fixing elements which are used to fix the shaft after the end play has been adjusted or compensated. The compensation elements include a spring element which is arranged inside the housing and which axially actuates the shaft. The fixing elements are not accessible from the outer side of the housing.

Abstract: The invention relates to a drive device comprising an electric drive motor, a housing, at least one shaft driven by the drive motor, compensation means enabling the end play of the shaft to be adjusted or compensated while the shaft is being mounted, and fixing means which are used to the shaft after the end play has been adjusted or compensated. The invention is characterised in that the compensation means comprise a spring element which is arranged inside the housing and which axially actuates the shaft, and that the fixing means are not accessible from the outer side of the housing.
