Patent DE-3126317-A1 (DE)
Title: Circuit for generating an output pulse string whose frequency is a linear combination of the frequencies of two independent input pulse strings
Inventor: KLAAS LOTHAR DIPL ING
IPC: H03L7/197
Filed: 1981-06-26
Abstract: The invention relates to a circuit which is able to combine additively the frequencies of two input pulse strings. The need for additive combination of two frequencies often arises in communications systems, control systems and measurement systems and this need has hitherto been met in most cases with the aid of a mixer with downstream bandpass filtering. For this purpose, the proposed circuit uses a modified phase-locked loop (PLL) and therefore requires no bandpass filter. The proposed solution can be integrated apart from one or, at the most, two capacitors.

Title: Curved channel
Inventor: BIERI HANS DIPL ING
IPC: F28F27/02
Filed: 1981-07-11
Abstract: The curved channel has deflection means for evening out the velocity distribution of the medium over the cross-section of the channel. A partially permeable element is arranged as deflection means on the concave wall surface of the channel transversely to the flow direction of the medium. The envelope surface of the element moves increasingly away from the wall in the flow direction on the inflow side like the concave side surface of a curved key. <IMAGE>

Title: Watercraft
Inventor: BREINBAUER ALFRED
IPC: F02B61/04
Filed: 1981-08-05
Abstract: In order to avoid transport difficulties with watercraft, sailing boats, motor boats and the like, where nonetheless a craft which is seaworthy in every respect is to be created, it is proposed to create a catamaran-like watercraft from two surfboards by two surfboards (1, 2) being connected to one another in parallel and at a distance from one another in a dimensionally stable manner by means of cross members (3, 5) and longitudinal members (4, 6), a mounting board (7) for an outboard motor (8) being provided on a rear cross member (5), the cross members (3, 5) and the longitudinal members (4, 6) being alternatively fastened in the surfboards (1, 2), and a covering (9) being provided between the cross members (3, 5) and the longitudinal members (4, 6). To transport the watercraft, the two surfboards (1, 2) can be separately fastened and the cross members (3, 5) and the longitudinal members (4, 6) can be stowed in a motor vehicle or a caravan. Serving to fasten the cross members (3, 5) and the longitudinal members (4, 6) are fastening bolts (14-17) which are arranged in openings (10-13) in the surfboards with bearing plates (18-21) in between and can be tightened by means of a threaded section (22-25) and a fastening nut (26-29). In a further development, a fastening device (64) for a sail pole (65) can be provided. To facilitate the transport of the cross and longitudinal members (3, 5 and 4, 6), these members can be of two-piece design and can be connected to one another via an articulated part. <IMAGE>

Title: Drive for adjusting a guided structural element
Inventor: BRAUN HELMUT
IPC: F16H57/00
Filed: 1981-08-26
Abstract: A drive, which serves for adjusting, for example, the sliding roof or a sliding window of a motor vehicle, is proposed. The actuating drive comprises a drive motor, a reduction gear following the latter, and a coupling which is arranged between the drive motor and the output element of the actuating drive. The coupling has a coupling piece which is to be brought simultaneously into engagement or out of engagement with a shaft of the actuating drive and with a gear member, in that the coupling piece is to be adjusted accordingly by means of a threaded element. When the unit is motor-operated, the coupling is in engagement. In the event of operating faults, the coupling is released, so that the member to be adjusted can be moved manually. <IMAGE>

Patent DE-3148601-A1 (DE)
Title: Arrangement of piezoelectric elements in passive glass breakage detectors
Inventor: QUERFURTH RUDOLF
IPC: G08B13/04
Filed: 1981-12-09
Abstract: In the arrangement of piezoelectric elements in passive glass breakage detectors, the invention proposes that in each case at least two piezoelectric elements are attached arranged at a specific angle relative to one another in accordance with their privileged direction and with reference to their sensitivity to mechanical vibrations. This angle is chosen such that upon the occurrence of vibrations characteristic of glass breakage at least one of the piezoelectric elements emits an output power sufficient to raise an alarm independently of the direction of said vibrations. The interconnection of the piezoelectric elements arranged in such a way means that the output powers add together, so that even in the event of an unfavourable occurrence of mechanical vibrations at the glass breakage detector a reliable raising of the alarm is ensured.

Title: Plant for generating a high electrical voltage for paint spray booths
Inventor: SCHENK ERICH
IPC: B05B16/00
Filed: 1983-01-03
Abstract: In order to equip such a plant, in an advantageous manner, for the electrostatic paint spraying of earthed articles which move through a spray booth which has a spray device at a high voltage relative to earth, instead of effecting the dangerous determination of the response of an overcurrent relay between the mains and the high- voltage generator and setting this relay to the desired high voltage, which procedure requires two persons, it is proposed, for a relatively simple, rapid and safe control of the relay and for setting it to new threshold values in each case with respect to the high voltage, to simulate the actual state of the plant without switching the generator on, in that a series connection of the relay and a microammeter is supplied by means of an auxiliary current source. A parallel connection of a plurality of resistors to the relay then permits the matching of the simulated conditions to the respective high voltage, with the stages of which the resistors are associated.

Title: Device for the failsafe representation of information on a data display device
Inventor: UEBEL HELMUT DIPL ING
IPC: G06F11/16
Filed: 1983-07-06
Abstract: The information to be represented, checked for correspondence by comparison and worked out in two mutually independent control processors (SP1, SP2) operating in parallel is converted into image data which can be processed by the data display device (BS) in two parallel screen drivers (BA1, BA2). The image data supplied by the two screen drivers are additionally checked for correspondence by comparison. This is done by the two control processors after previous data reduction by means of two shift registers (RSR1, RSR2) with feedback. The data display device (BS) is in each case driven by one of the screen drivers (BA1). A screen driver essentially contains an image processor for generating the image data, an image refresh memory, a clock generator and control logic for providing the control signals for the associated shift register with feedback. If the data display device is a colour monitor, the image data are compared in an independent device for each primary colour. <IMAGE>
