Patent DE-4226620-A1 (DE)
Inventor: BEYER ECKHARD DIPL ING DR ING
IPC: B23K26/40
Filed: 1992-08-12
Abstract: The invention relates to a process for the laser beam cutting of strip or plate workpieces at high speed, especially over 100 m/min. The laser beam melts the workpiece with the formation of a vapour capillary at the cutting point and the melt is driven off by a cutting gas consisting of an inert gas/hydrogen mixture. In order to maintain the vapour capillary, the hydrogen component of the cutting gas mixture is set so high and this cutting gas mixture is taken to the surface of the melt at the cutting point at such a pressure and with such a pressure distribution that the temperature at the surface of the melt is kept at boiling point and the melt is continuously driven out of the cutting seam on the side away from the cutting direction of the vapour capillary.

Title: Compensating for wear and temp. differences at brake units of vehicle - using pressure control, position sensor to detect operation and electronic control unit picking up signals of sensors of brake units
Inventor: KLEIN GUENTER DIPL ING
IPC: F16D66/00
Filed: 1992-09-17
Abstract: When different brake unit position sensor signals are received at the electronic control unit (8), the higher signal causes a pressure change at the lower signal. During operation of the braking unit, a variable number of regulating cycles is carried out. These include: pressure control, signal determination and signal evaluation, resulting in pressure changes. During a first phase of the operation, a low number of regulating cycles are carried out to compensate for wear. In a second phase,  a higher number of regulating cycles is undertaken to compensate for the pressure differences. ADVANTAGE - In one phase only small heating influence exists; in second phase, measures are taken to reduce unpermitted thermal loading. Brake lining wear is reduced and higher quality of temp. compensation results.

Title: Steering lock for vehicles
Inventor: WITTWER REINHARD
IPC: B60R25/021
Filed: 1993-03-09
Abstract: In the case of a steering lock for motor vehicles, a cylinder guide is used to support a key-actuated cylinder core such that it can be rotated about its axis. The cylinder guide is accommodated at one end in a lock casing such that it is stationary with respect to its axis and can be freely twisted in an inherently free running fashion on the other side. The cylinder guide is, however, held tight conventionally by a disc cam. This is brought about by means of axial engagement of at least one cam/recess pair which is provided between the cylinder guide and the cam shaft. An eccentric shaft is used to control a locking pin which blocks the steering wheel of the motor vehicle when the key is pulled out, and to control an ignition switch associated therewith. When the cylinder core is actuated by means of a key, the eccentric shaft is pressed away from the axis of the cylinder guide by means of axial extension of at least one projection from a recess against the resistance of a spring and in so doing interacts with an anti-key-withdrawal device. Between the eccentric shaft and the cylinder core there is inserted an intermediate element which can be displaced axially in the lock casing, can be rotated with respect to the cam shaft and can be coupled to the cylinder core in a nonrotating manner. Although the cylinder core is conventionally connected, via the intermediate element, to the eccentric shaft as well in a nonrotating fashion, it is freely rotatable, together with its cylinder guide, with respect to the eccentric shaft if the cam disc runs freely against the action of an axial restoring force. In order to design a space-saving steering lock with less components, it is ... Original abstract incomplete.

Date Sep. 29, 1994A serial data stream of control commands is sent to a shift register having a delay time corresponding to a shift frequency which is a multiple of the maximum expected bit rate, each control command beginning with a uniform binary character having a start sequence with a maximum duration. The bit rate is calculated from the duration of the start sequence which is measured by activating a counting circuit during the time in which the data stream is passing through the shift register. The bit rate is programmed into an integrated serial data transmission component, preferably a UART, and the delay time of the shift register is determined according to the maximum duration of the start sequence, plus the time required to program the bit rate into the UART.
