Title: Combined wear and braking indicator for disc brakes
Inventor: HILLE WOLFRAM
IPC: F16D66/02
Filed: 1988-02-22
Abstract: To reduce the outlay on equipment, and to allow information to be obtained by the use of a combined wear and braking indicator, an indicator for disc brakes is designed in such a way that it indicates the digital pressure signal corresponding to the limiting wear or the analog pressure signal corresponding to the continuous wear when the release clearance with the brake applied is 0. This is achieved by virtue of the fact that two pistons with a common longitudinal axis are guided in opposite directions as regards the pressure direction and, with their specially designed ends, are in contact with geometrically identical eccentric features on a pivotable shaft. <IMAGE>

Title: Video device with an equalizer circuit in the signal path for the frequency-modulated signals
Inventor: REIME GERD
IPC: H04N5/93
Filed: 1988-03-21
Abstract: In the signal path (1) for transmitting the frequency-modulated video signals of a video recorder, an equalizer circuit (9) for equalizing transmitted luminance steps is arranged which contains a filter circuit element (10) located in the signal path (1) which is followed by a coupling element (11) and a diode switch (20) which is connected in parallel with the signal output (19) of the filter circuit element. In the case of low transmitted oscillation amplitudes, the diode switch is blocked so that the filter circuit element and the coupling element form a band-pass filter (12) which is tuned to the transmitted oscillations and which stabilizes and equalizes the transmitted oscillations. In the case of large-amplitude signals, the diode switch, together with the filter circuit element, forms a voltage-dependent transit-time shift which steepens again the luminance steps which were flattened during the transmission. <IMAGE>

Title: Method for forming the coil overhangs of stators of electrical machines
Inventor: VESER FRANZ
IPC: H02K15/06
Filed: 1988-04-16
Abstract: A method using a mandrel which can be expanded radially is proposed for forming the coil overhangs of stators of electrical machines after the coils have been drawn in. In this case, it is necessary for the forming device to be designed such that the forming work can be carried out as long as the stator is located in the same clamping device in which it is also held for the coils to be drawn in. The use of a clamping mandrel is proposed having two mandrel sections which can be pushed axially into one another, on which pressure strips (11) are mounted via scissor-levers (9, 10). An expanding body (8) is placed on the front mandrel section. While the front mandrel section is seated on a stop (15), the rear mandrel section is pressed against the front mandrel section by means of a linear-motion device which is also used for drawing in the coils (see drawing). <IMAGE>

If a processor receives data from external equipment (161), it stores data with an event number which is assigned to the input data on the basis of the content code (CC), and determines, by comparison with the event number in a buffer of the processor, whether a predefined number of data items with event numbers has been received. <IMAGE>
Patent DE-3900633-A1 (DE)
Title: Facsimile control system
Inventor: TSUMURA NAOKI
IPC: H04N1/32
Filed: 1989-01-11
Abstract: A facsimile control system for a facsimile machine contains an additional equaliser in order to compensate for the high-frequency characteristics of a communications network. The additional equaliser is placed into a state of use or non-use in dependence on the conditions for the retransmission of picture information of those individual pictures for which errors have appeared. Alternatively, the characteristic of the additional equaliser varies as a function of the conditions for the retransmission. Having this structure, it is not always necessary to carry out a data reduction operation in order to reduce the data transmission rate when data transmission errors have occurred so that the data transmission rate can be kept at maximum.

Abstract: This flying object is a biplane equipped with four engines, the upper wings of which biplane can be converted to form a rotating wing. The flight vehicle itself is mounted in a load-bearing manner by means of connecting pieces on the hollow shaft which passes vertically upwards and in whose interior an oil line and the necessary cable lines are also passed upwards. A hub having two ball-bearings is fixed to the hollow shaft above the fuselage, such that it can rotate between two fixing rings. The hub is completely surrounded by plates and is welded to them on the left and right. The wings are welded to round, robust discs which run displaceably in a flange guide which passes all round and is firmly screwed on the left and right to plates which are welded to the hub. During take-off and landing, the wings are caused to rotate by the two engines. After altitude has been achieved and the lower engines have been started, the upper engines are switched off and the wings are locked once they are stationary. The right-hand engine is pivoted through 180@C and in consequence points in the correct rotation direction. It can be switched on again and is then used again for cruise to the destination using four engines. The upper engines are supplied from a distributor tank which is mounted on the hub, also rotates, is fed from a supply tank mounted on the hollow shaft, and is refuelled by means of the ...

Patent DE-3916202-A1 (DE)
Inventor: GLEIM GUENTER
IPC: H03M1/68
Filed: 1989-05-18
Abstract: A high linearity digital-to-analog converter (D/A) provides a linear output voltage using two D/A's. One D/A provides a number of coarse steps and another D/A increments the output voltage within the coarse steps using fine steps. Discontinuities in the output voltage caused by the changing from one coarse step to another are avoided by using reference voltages which ensure that the initial voltage available at the start of a coarse step is lower than the final voltage available at the end of the preceeding step.

Patent DE-3932468-A1 (DE)
Inventor: GOUGH RICHARD JOHN
IPC: F16K15/03
Filed: 1989-09-28
Abstract: A fluid flow non-return valve comprises a valve body (10) defining a passage (12). A valve disc (22) is movable in the passage against bias of spring 24 to permit the flow of fluid. The disc is actuated by an aneroid capsule (28) in response to the pressure in the passage upstream of the disc. The capsule is connected to the disc by lever arm (30). Thus, when the pressure in the upstream part of the passage increases to a certain value, the valve will open. The valve is substantially independent of the pressure downstream of the disc and is, therefore, not reliant on a differential pressure across the disc. <IMAGE>
