Title: Machine for scaling fish, especially medium-sized fish
Inventor: SCHAEFLER JUERGEN
IPC: A22C25/02
Filed: 1985-06-18
Abstract: A machine for scaling fish is shown and described which is intended to replace the cumbrous and time-consuming scaling of fish by hand. The known mechanical devices are generally complicated and expensive, so that their use is unprofitable in relatively small enterprises. To eliminate these disadvantages, the invention makes use of a slowly rotating cylinder drum (1), into which a plurality of longitudinally positioned fish (F) are introduced. The drum wall is provided with a multiplicity of inwardly pointing scraping pins (4) and is perforated in such a way that the water entering from below ensures that the fish in the drum display good sliding characteristics at all times and simultaneously flushes out the scales which have been removed. <IMAGE>

Title: Digital method and device for synchronous control of a mains-commutated converter
Inventor: URBANKE CHRISTIAN DR ING
IPC: H02M1/084
Filed: 1985-06-26
Abstract: The pulse-forming device (Imp) of a mains-commutated converter (SR) receives a mains-synchronous reference voltage (Ur) and a gating angle  alpha i, which is calculated in accordance with a control law, memories (MS, MR) resulting in the calculated triggering angles being maintained and the reference voltage (Ur) continuing to run in an unsynchronised manner in the event of a failure in the synchronising section and/or in the control section. If, for example, the disturbance continues for a relatively long period, then the calculated triggering angles ( alpha i) are replaced by standby triggering angles ( alpha E) which are stored in a further memory (ME) in accordance with operation of the converter in the invertor limit position or another, suitably specified standby mode. In consequence it is possible, for example to reduce the current through the converter and finally to cut it off in a well-ordered manner in the standby mode. <IMAGE>
Patent DE-3523467-A1 (DE)
Title: Method for digital transmission of analogue signals
Inventor: SCHENKYR RAINER DIPL ING
IPC: H03M5/20
Filed: 1985-07-01
Abstract: Using this digital transmission method, the signal to be transmitted is converted into more than two-valued code elements, and, in this process, the levels of the characteristic states of the more than two-valued code elements display different values. As the larger level differences in more than two-valued code elements are assigned to the larger value differences, there is an overall reduction in errors which arise at the receiver end when assigning the levels to the value intervals. Use of this method in the context of the transmission of digitized analogue signals, for example in video transmission systems or measurement value transmissions, can therefore provide significant improvements in image or analogue signal quality at the receiving end, or an increase in the transmission distance for the same image or signal quality, which is particularly advantageous in the area of optoelectronic transmission systems.

Patent DE-3535671-A1 (DE)
Inventor: REINHART KARL-FRANZ DR
IPC: G11B5/035
Filed: 1985-10-05
Abstract: Magnetic head (49) for reading digital magnetic information on a magnetic recording support (9), in which three or more magnetic sensors (12, 13, 14) are provided per recording track. An increase in the recording density of signals on the magnetic recording support (9) is achieved by equalization of the playback signals in the local region. The desired reduction in the half amplitude width (33) of playback signals is achieved by the interconnection of the output signals which differ in value and polarity from at least three sensors (12 to 14), which simultaneously scan the environment of a magnetic flux change in the information carrier. The distance between the sensors (12 to 14) in the recording direction (11) corresponds approximately to half of the half amplitude width (33) of the local resolution of the central sensor (12). The differing value of the output signals (32, 34, 35) occurs because of the differing geometrical dimensions of the sensors (12 to 14). The different polarity of the signal (32) of the central sensor (12) compared with the signals (34, 35) of the adjacent sensors (13, 14) can be obtained, in the case of magnetoresistive sensors by the choice of the operating points (68, 69, 70) in the regions of increases in the characteristic curve having differing signs. The equalization in this magnetic head arrangement operates irrespective of the speed at which the magnetic recording carrier (9) moves.

IPC: H01B13/02
Filed: 1985-10-12
Abstract: The invention relates to a device for alternate-lay helical stranding of a cable with at least one stranding element around a core element using a strand-laying disc driven with alternating direction of twist and a stationary disc and with strand offset discs driven in the same direction as the strand-laying disc and at the rate of the alternating twist and arranged between the stationary disc and the strand-laying disc. The fluctuations in length of the sections of the stranding elements stored intermittently between the stationary disc and the strand-laying disc are reduced by the fact that the strand offset discs (15 to 21) are driven with essentially the same rotational speed but at an angle of twist that reduces in stages towards the stationary disc (14) in such a manner that during each half period (t1 or tr) of the alternate-lay helical stranding (clockwise or anticlockwise) rotation of the strand offset disc (21) adjacent to the strand-laying disc (11) starts with a delay of a defined angle of rotation  beta  and that of the following strand offset discs (20 to 15) starts with a delay of an angle of rotation of an equal amount compared with the previous discs (21 to 16). <IMAGE>

Title: System for the recovery of braking energy, especially for motor vehicles
Inventor: SIAKOS LAOPHILOS
IPC: B60T1/10
Filed: 1985-11-04
Abstract: In a normal braking sequence the kinetic energy of a motor vehicle is irreversibly converted into heat. By means of a mechanical (coil spring) or pressure storage device, some of this energy can be optimally fed in by mechanical or pneumatic means to then be utilised in starting. The spring energy is released to the mechanical energy storage device so that, by means of a locking pawl and an equal-sided coupling, the spring relaxation direction = direction of rotational travel. When starting the pressure energy is drawn from the pressure storage device, to which the internal combustion engine has functioned as a compressor during the braking period, in such a manner that the compressed working medium (exhaust gases or air) is fed into the intake pipe. Compression in the cylinder chambers is avoided by control of the outlet valves. <IMAGE>

Title: X-ray examination arrangement having an image recorder (camera)
Inventor: KOSE ERWIN
IPC: H05G1/36
Filed: 1987-02-16
Abstract: The invention relates to an apparatus for slit radiography, in the case of which the fan-shaped beam emerging through the slit is divided by a plurality of filters into different beam areas in which the dose power is matched to the respective requirements by displacement of the filters, the position of whose thickness is variable. According to the invention, the filters contain elements (or consist completely of such elements) whose absorption edge is located relatively close to the maximum quantum energy contained in the X-ray beam. In consequence, the mean energy of the X-ray radiation is reduced as the object thickness decreases, which improves the contrast of the X-ray image. <IMAGE>

Title: Arrangement for preventing oscillation in the absence of a signal
Inventor: LEE SANG YONG
IPC: H04N5/775
Filed: 1987-04-15
Abstract: The invention relates to an arrangement for preventing oscillation in the absence of a signal to prevent the occurrence of any oscillation (or beat) when an interference signal is generated in a feedback loop formed between audio signal input and output terminals of a video cassette recorder and a television receiver when no signal is present. According to the invention, the transmission line of a buffer, operated by an emitter follower, between the audio signal input and output terminals of the video recorder is provided separately from the transmission line extending via a tuner/line change-over switch and an amplifier. In the normal state, in which a vertical synchronisation signal is picked up, a feedback loop is formed via the transmission line extending through the tuner/line change-over switch and the amplifier. In the no-signal state, in which no vertical synchronisation signal is picked up, a feedback loop is formed via the transmission line of the buffer so that no oscillation occurs in the no-signal state (when no signal is present) and thus the output or reproduction of an oscillating interference signal is prevented. <IMAGE>

Title: Spring brake cylinder with an emergency release device
Inventor: RABE HERMANN
IPC: B60T13/22
Filed: 1987-07-17
Abstract: A spring brake cylinder (1) has a housing (2, 20) with a hollow-cylindrical extension (4) in which a piston (5, 6) is arranged so as to be displaceable by a pressure medium. This piston acts against a radial widening (10), adjoining which is a guide tube (9, 90). This guide tube is penetrated by a guide journal (15, 15') on which is pivoted a rocker pivot (16, 16') to which are attached two Bowden cables (24, 24') which operate the brake. Arranged in the guide tube (9) there is furthermore a receiving pin (18) with a slot (19) which is displaceable relative to the guide journal (15) to form an emergency release travel (a). The housing (2) furthermore carries two diametrically opposite and radially displaceable fixing pegs (32). During the production of the braking operation, the receiving pin (18) is locked by these pegs while maintaining the emergency release travel (a), while, for emergency release of the brake, the locking pegs (32) are displaced radially outwards, thereby enabling the emergency release travel (a). <IMAGE>
