For connection of pipelines which are subject to vibration, for example pipelines in vehicle exhaust systems, a liquid-tight decoupling element is used which includes a, e.g. multi-layer wound, metal hose and a tube accommodated in coaxial relationship inside or outside of the metal hose. A first axial fitting firmly secures one end of the tube. The tube is sized to protrude into a second axial fitting, regardless whether the metal hose is completely compressed or completely stretched, to allow movement of the tube in axial and torsional directions in relation to the second axial fitting.

The invention relates to a bilateral drive for rotating in the one or the other direction of drive a drive wheel which is linked with an adjusting device. Said drive comprises a drive lever which can be rotated about a drive axis, starting from an initial position, in the one or the other direction. Said lever is linked with a coupling element for expanding a spring element that is at least partially supported by the cylindrical drive surface of the drive wheel and that entrains the drive wheel in the peripheral direction when the drive lever is moved away from the initial position, while the spring element is no longer supported by the cylindrical drive surface of the drive wheel and the drive wheel is not entrained when the drive lever is returned to the initial position. The coupling element comprises expansion cams that can be tilted about an axis spaced apart from the drive axis. The expansion cams expand the actuation lever which is linked with the spring element in such a manner that the spring element which is supported by the cylindrical drive surface of the drive wheel is expanded.

A method for controlling functional units in a processor, according to which in a configuration a sequence of primary instruction words which consists of several instruction word parts and originates from a translation of a program code is compressed and stored as a sequence of associated program words. The invention also relates to a processor system for carrying out this method. The aim of the invention is to increase operating speed in an application-specific manner while retaining a low program word width. To this end, as regards the method, a program word contains a first characteristic of a primary instruction word and instruction word parts which differentiate the primary instruction word belonging to the program word from the primary instruction word belonging to the characteristic. By means of the first characteristic contained in the program word a secondary instruction word is generated by exchanging the instruction word parts contained in the program word with those in a preceding secondary instruction word. On the system side the aim of the invention is solved by providing for the instruction word buffer to consists of a memory with optional line-by-line access.

A power switch includes switch contacts that are opened via a switch shaft, which, when the switch is triggered, is actuated by way of the trigger slider of a trigger unit, in particular a working current trigger unit. The trigger slider moves the switch shaft by way of the trigger shaft of a switch latch, the trigger unit including electric coil into which an armature extends that is drawn into the coil by electromagnetic forces of attraction when the switch is triggered. A stationary counter armature is disposed in the coil, which counter armature serves as a stop for the armature, so as to increase the forces of attraction. The movement of the armature is transmitted by way of a mechanism to the movement of the trigger slider so as to increase the displacement path of the trigger slider.

In order to improve the functionality of a computer-assisted design, test and/or development environment for a data processing circuit arrangement, the instructions of the circuit arrangement are stored in a machine-readable manner in a data base with the binary representations thereof. The allocation of a predefined binary representation (instruction code) to an instruction occurs in a modifiable manner. In this way, processors can be developed which are specialized and optimized in terms of processing specific software applications. The invention also relates to a computer-assisted design, test and/or circuit environment corresponding the above-mentioned method.

The invention relates to a method and an arrangement for instruction word generation in the controlling of functional units in a processor, the instruction words comprising a plurality of instruction word parts. In this case, in a program sequence, under the control of a program word, an instruction word is taken from a row—determined by a reading row number—of an instruction word memory that can be written to row by row, the said instruction word is altered by means of substitution of an instruction word part by the information part of the respective program word and is written back to a row of the instruction word memory, the said row being determined by a writing row number. Afterwards, an instruction word—which is generated in this way and is to be executed in accordance with the program—for controlling the functional units is output to the processor.According to the invention, a reduction in the processing width and an increase in the operating speed is achieved by the writing and reading row numbers being generated by corresponding registers and/or the largest possible number of instruction words that are to be executed being successively compiled in the instruction word memory and processed, so that they are combined in blocks. This makes it possible to reduce the processing width during the program word processing in the part which carries control information.

An adjustment fitting, in particular for a vehicle seat, comprising a first fitting part and a second fitting part that can be rotationally adjusted relative to the first part about an axis of rotation. An external gear, which has internal teeth and into which an internal gear that is associated with the second fitting part and has external teeth is inserted eccentrically to the axis of rotation like an eccentric gear, is associated with the first fitting part. The internal gear forms an eccentric receiving space towards the axis of rotation. The adjustment fitting further comprises an eccentric member that is rotatably inserted into the eccentric receiving space, and a drive shaft for driving the eccentric member. The external gear is designed as a ring gear that has a bottom and an external wall which axially extends beyond the internal teeth. Furthermore, a holding element is provided which can be axially slid against the internal gear in the external wall, is mounted on the external wall, and secures the internal gear against the bottom of the ring gear. The holding element allows the axial tolerance between the internal gear and the external gear to be adjusted.
