Abstract: A system for providing maintenance and repair units for maintenance work on an aircraft includes a maintenance and repair unit having a frame structure which carries equipment and which is transportable, and a transport vehicle having a lifting device which can raise, set down, and transport the maintenance and repair unit.

Abstract: A transport vehicle includes two non-steered drive wheels, two non-driven steered load wheels, drive motors for driving the drive wheels, a steering target value encoder, a device for detecting the steering angle of one of the load wheels, and an electric control unit. An actuation of the steering target value encoder displaces a steering pole along a steering pole axis. The steering target value encoder steers each of the load wheels from a first position in which the load wheels' axes run parallel to the drive wheels' axes into a second position in which the load wheels' axes are oriented to the steering pole which lies between the drive wheels. The electronic control unit influences a rotational speed of the drive motors as a function of the steering angle and reverses a direction of rotation of at least one of the drive motors as a function of the steering angle.

Abstract: A releasable plug connection for inserting a nozzle tube into a jack includes a hollow cylinder and a sleeve displaceably mounted on the cylinder. A nozzle tube, forming the hollow cylinder, is provided with radially spring-loaded lugs, the free ends of which are in contact with a locking surface. The locking surface is formed on a flange of the sleeve, which can slide relative to the hollow cylinder against the force of a spring. To release the connection, the sleeve is pushed back so that the lugs are pushed inwardly, and ends of the lugs slide from the locking surface. As soon as the lug ends have left the locking surface, the nozzle tube shoots from the jack under the action of the spring.

Abstract: The invention relates to a releasable plug connection, for inserting a nozzle tube (2) into a jack (1), consisting of a hollow cylinder (3) and a sleeve (6) displaceably mounted on said cylinder. To this end, the nozzle tube (2) is provided with radially spring-loaded lugs (20), the free ends of which are in contact with a locking surface (10a). The locking surface is formed on a flange (10) of the sleeve (6) which can slide relative to the hollow cylinder (3) against the force of a spring (24). For releasing the connection, the sleeve (6) is pushed back so that the lugs (20) slide along a truncated cone (14) on the hollow cylinder (3) and are pushed inwardly in the process. As a result, the ends of the lugs (20) slide from the locking surface (10a). As soon as the lug ends have left the locking surface (10a), the nozzle tube (2) shoots from the jack (1) under the action of the spring (24).

Abstract: A mouth rinsing device comprising a pump housing and a reservoir. These two housings are arranged in series; i.e., the reservoir is attached to the base of the pump housing. A riser tube having a head on its end is situated on the pump housing and is fixed there by means of a lock so that only the head protrudes. When the reservoir is attached the lock is simultaneously released, so that the riser tube is able to slide into the reservoir and the intake opening is situated just above the base. After the reservoir is removed, the riser tube may be pushed in again manually. The riser tube is subsequently fixed in the retracted position by locking the head to the base of the pump housing.

Abstract: In order to enable treatment agents such as mouth water or abrasive substances to be added to the spray water in an oral douche, the hand piece of the oral douche is provided with a mixing reservoir that includes a mixing chamber on the lower end of the hand piece. The mixing chamber is arranged in the main or subsidiary flow of the spray water supply line. A water-soluble tablet containing the treating agents is arranged therein. Mixing of the treating agents is determined by the shape and size of the supply and discharge line to the mixing chamber.

Abstract: An electric toothbrush with a handle and a brush member having a brush head, individual cylindrical bristle holders with tufts of bristles held rotatably in the brush head. They are set into an oscillatory rotating movement by means of a connecting rod executing a reciprocating sliding movement and simultaneously an oscillatory movement about its longitudinal axis, with transverse grooves, disposed therein. In addition, a bristle holder plate in the brush head is held so as to oscillate about a shaft running in the longitudinal direction of the toothbrush. Thus, during the oscillatory movement of the bristle holders the bristle holder plate swivels back and forth in synchronism with the connecting rod.

Abstract: An electric toothbrush having a cam disc mounted at the free end of a toothbrush shaft and which engages between two follower pins of a bristle carrier disc. The form of the cam disc is approximately elliptical. This causes it to impart a reciprocating motion to the bristle carrier disc when the toothbrush shaft is driven in rotation.

Abstract: A fluid reservoir for an oral hygiene appliance has a floor valve in its floor which opens when the reservoir is placed on the oral hygiene appliance. The fluid reservoir is subdivided into two separate fluid chambers, each with a fluid outlet leading to the floor valve. The fluid outlets can be controlled by a manually operable selector valve in such a way that one fluid outlet is opened and the other is closed alternately.
