摘要:
The present invention relates to a hydraulic vehicle brake equipped with a parking brake device, in particular for motor vehicles, including a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, wherein the parking brake device acts on the brake piston and, in the applied condition, can be locked by means of a locking device, and an energy accumulator cooperating with the brake piston is equipped with at least one integrated spring element. In order to realize a simple and low-cost parking brake function that complies with legal requirements, according to the invention, the parking brake device is operable by a pressure that is introduced into the service pressure chamber and enables charging the energy accumulator.

A rolling train for structural shapes in which at least on one side of a train having a plurality of mill stands, e.g. universal mill stands, a detector is provided for the actual profile of the rolled product. The actual profile is compared with a setpoint profile and corrected setpoint values for the operating parameters of the individual stands are generated for a corrected subsequent rolling operation or even the same rolling operation, appropriately weighted for the contribution of the various stands to the rolling effect.

An identifier is provided for an integrated circuit with a memory composed of a multiplicity of memory cells. The circuit has a manufacture-related memory cell defect pattern formed of defective memory cells. The method of identifying the integrated circuit utilizes the memory cell defect pattern to generate a circuit identification number for identifying the integrated circuit.

A method identifies a pulse sequence having known values and a known length in a signal. According to this method, the mathematical sign of the phase difference between samples of the signal is used to estimate whether the transmitted pulse is a 1 or a 0. Undersampling, carried out to a selectable extent, produces a relatively insensitive response to adjacent channel interference. The sum of the pulses in a window which is proportional to the length of the pulse sequence and to the extent of the undersampling is determined, with the pulse sequence being regarded as being identified at the point in time at which the sum of the pulses in this search window exceeds a threshold value.

The indirect plasmatron comprises a neutrode assembly comprising a plurality of plate-shaped electrode members which are electrically insulated from each other. In its interior, the neutrode assembly defines an elongated plasma channel. The outlet aperture for the plasma torch is in the shape of an elongate slot and extends parallel to the central longitudinal axis of the plasma channel. Each of the two electrodes of the plasmatron is surrounded by a cavity through which an inert gas can be fed into the plasma channel. For the purpose of stabilizing the electric arc, at least one pair of permanent magnet members is provided. Their magnetic field exerts a force onto the electric arc which is directed opposite to the force exerted onto the electric arc by the flow of the plasma gas. Particular neutrodes are provided with a channel for feeding a further gas into the plasma channel.

A method for detecting a fault of an operating switch connected to an evaluating unit by at least one signal. The switch having at least a first switch circuit for initiating a vehicle function. A signal that specifies the switch position is sensed by the evaluating unit. The first switch circuit is connected to a first potential of the vehicle electrical system and to the signal line to form a first contact branch. The first switch circuit is bridged by a diode device in the non-conducting direction with respect to the first potential, the evaluating unit generates a test voltage, which is greater than the first potential, the test voltage is applied to the signal line, and, the potential being applied to the signal line of the first contact branch is evaluated by means of the evaluating unit in order to detect a fault.
