Title: Drive unit with a drive motor, preferably an electric drive motor
Inventor: URSEL ECKHARD
IPC: F16H57/022
Filed: 1984-06-23
Abstract: The invention proposes a unit which is used for driving devices belonging to a motor vehicle, such as, for example, sliding roofs, window winders etc. The drive unit comprises a preferably electric drive motor and a gear mechanism which is connected to the output of the latter, is accommodated in a housing and the worm shaft of which is held without backlash in the direction of its longitudinal axis by means of an adjusting screw which can be screwed into the housing against an end face of the shaft. The adjusting screw is locked in its prescribed operating position by an anti-rotation safeguard. A particularly expedient anti-rotation safeguard, which is, in particular, operationally reliable even when the housing is made of a plastics material, is achieved by the fact that a wall determining the axis of rotation of the adjusting screw is arranged on the outside of the housing and a cap is secured on the said wall in a manner secured against rotation. The cap has at least one fitting surface, which interacts without play with a mating fitting surface of the adjusting screw arranged on that side of the adjusting screw which faces away from the shaft. <IMAGE>

Patent DE-3435032-A1 (DE)
Title: Device for filtering or correlating bandpass signal forms
Inventor: BAIER PAUL WALTER PROF DR ING
IPC: H03H19/00
Filed: 1984-09-24
Abstract: Filters or correlators for bandpass signal forms can be implemented in the baseband according to the quadrature principle. If the equivalent low-pass signal form with which filtering or correlation is to be performed has a complex value, four channels are required in the filter or correlator per se. According to the invention, the problem of being able to reduce the number of channels for the time-discrete filter or the time-discrete correlator (7) to two is solved by connecting a suitable series device (6) upstream of the channels. Unlike state-of-the-art systems, the system according to the invention offers the advantages that it can be used more generally and for a larger class of signal forms and that the mixing frequency (fM) in the quadrature demodulator (1) can often be selected as equal to the mid-frequency of the input signal s(t), which renders the technical implementation of the quadrature mixers (M1, M2) and the required anti-aliasing low-pass filters (TP1, TP2) less critical. The device according to the invention is suitable for use as a signal-matched filter or correlator for radar signals or spread-spectrum transmission signals. <IMAGE>
