Abstract: The invention relates to a method for running communication services or a corresponding service logic in a communication system (UMTS), whereby a station (A, B) logs on to an access device (PA or PB) of the communication system (UMTS), and service-related instructions depending on a service logic relating to the station (A or B) are emitted on the network side, in a network device on the connection path between the station (A, B) and another station (B or A). The aim of the invention is to enable the service logic to be updated without having to transmit it from the station with, for example, registration data each time. To this end, the service logic relating to said station (A or B) is called by the device (PA or PB) emitting the instruction, from a service data bank (DD) in which the service logic is stored on the network side.

Abstract: The invention relates to a switching device for a parking brake, especially a commercial-vehicle parking brake, with a handle that can be moved between a pulled position for engaging the parking brake and a pushed position for releasing the parking brake, and to such a parking brake. The handle is subjected to a preload force toward a central position when it is in the pulled or pushed position. Depending on the position of the handle, an evaluation device outputs different control signals for an actuating device of the parking brake.

Abstract: A pulse tool, in particular a pulse nutsetter, has at least one pneumatic drive unit with a drive rotor and a pulse unit driven by the drive unit, wherein a delay-dependent inertial cut-off device is assigned to the drive unit for the interruption of the air feed on acquiring a cut-off pulse. A pulse tool of this nature is improved to the effect that it has or facilitates a compact design, a low weight and simultaneously a fast cut-off by the inertial cut-off device. This is achieved in that the inertial cut-off device has at least one cut-off piston for changing the air feed between the open and closed positions and which can be moved relative to the drive rotor and an, essentially annular, inertial body which can turn with the drive rotor. Due to the inertial body, on acquiring the cut-off pulse at least one drive body, essentially radially adjustable relative to the drive rotor, can be deflected by means of an internal contour.

Abstract: The invention relates to a rail-bound vehicle for an amusement park ride. The vehicle has an upper part 10 with vehicle seats 12, as well as a carriage 20 whose running wheels 22 and lateral wheels 23 run on rail-tubes, as do its lift-off rollers 24. The upper part 10 can rotate freely around a vertical axis 16 relative to the carriage 20. A brake disk 14? made of a metallic material is provided on the underside of the upper part 10. Permanent magnets 31 connected to the rail system are assigned to this brake disk 14?. The brake disk 14, upon passing these permanent magnets 31, enters the latter's magnet field, with the result that the upper part 10 of the vehicle is braked and set into rotational motion due to the continued linear movement of the carriage 20.
