Abstract: Disclosed is an ultrasonic shock wave head for use in lithotripsy, comprising a shock wave source (2) and an acoustic lens (6) for focusing the ultrasonic shock wave generated by the shock wave source (2). A bearing housing (8) for the shock wave source (2) is molded onto said acoustic lens (6) as a single piece.

Abstract: A device to adjust the focus position of the therapy head of a lithotripsy system having an x-ray system, has a cross-hair disc that can be attached to an image intensifier of the x-ray system, such that extending away from the edge of the cross-hair disc are variable-length connection elements whose outer end facing away from the cross-hair disc can be indirectly or directly affixed to the image intensifier.

Abstract: An axially adjustable steering column for vehicles is disclosed which has an axially displaceable steering shaft which is surrounded by two steering column jacket parts which can be pushed together in a telescopic fashion. The jacket parts can be attached to one another by way of a clamp connection. The jacket parts are axially movable with respect to one another when the clamp connection is loosened with the displacement of the steering shaft. The clamp connection has at least one threaded pin which is radially movable with respect to the longitudinal axis of the steering column jacket parts and is received on the outer steering column jacket part in a threaded section and after its screwing-in movement presses against the internal steering column jacket part. A spring-loaded control cable is provided which acts in a rotating fashion on the threaded pin.
