Patent DE-3638665-A1 (DE)
Inventor: JONNER WOLF-DIETER ING GRAD
IPC: B60T8/66
Filed: 1986-11-12
Abstract: PCT No. PCT/EP87/00415 Sec. 371 Date Apr. 28, 1989 Sec. 102(e) Date Apr. 28, 1989 PCT Filed Jul. 30, 1987 PCT Pub. No. WO88/03490 PCT Pub. Date May 19, 1988.An anti-lock braking system is specifically designed for a motor vehicle having four-wheel drive and a device for shifting between two-wheel and four-wheel drive incorporating a lockable central differential. Additional differentials at the front and rear axles may also be locked to avoid wheel spin. The anti-lock braking system produces a brake pressure reduction signal when the wheel speed falls below a reference value. In accordance with the invention the reference value is varied in dependence upon whether the vehicle is shifted into two-wheel or four-wheel drive, in dependence upon the engagement of the central differential lock, and/or in dependence upon the engagement of the other differential lock(s).
Patent DE-3639519-A1 (DE)
Title: Flush valve
Inventor: SCHENCK ZU SCHWEINSBERG AXEL-W
IPC: E03D3/04
Filed: 1986-11-20
Abstract: Flush valves are usually constructed such that the flushing procedure carries on for as long as the actuating knob is pressed in. This can result in unnecessary water consumption if the actuating knob remains pressed in until the flushing of the WC has finished. Then, when the actuating knob is subsequently released, still more water flows out unnecessarily because such flush valves close in a delayed manner after the actuating knob has been released. In order automatically to trigger the closure of the main valve by manipulating the actuating device, said actuating device has a coupling member which can be resiliently pivoted away transversely to the movement direction of the closure body and produces the operative connection to the closure body. Moreover, the valve housing has a stationary sliding ramp which is fixedly connected to it and against which, on reaching the full displacement of the actuating device, the coupling member can be pressed for uncoupling by lateral pushing-away. <IMAGE>
Patent DE-3700864-A1 (DE)
Title: Variable-speed friction-wheel mechanism (circular mechanism)
Inventor: SCHEUERMANN WALTER DIPL ING
IPC: F16H15/28
Filed: 1987-01-14
Abstract: The invention relates to a variable-speed friction-wheel mechanism in which a driven rolling element with circular outer contours is frictionally connected via a pivotable friction wheel (round disc) to a second rolling element of identical design. The two rolling elements are at 90@ to one another and their circular arcs lie on a common circle, the diameter of which is equal to the diameter of the connecting friction wheel. The rolling elements have a maximum and a minimum diameter due to the position of the centre of the common circle. The range of variation is the result of the relationship between the two diameters. If different transmission stages are connected in series, very large ranges of variation are obtained by multiplication of the diameter ratios. If transmission stages are arranged in parallel, the frictional force transmitted is multiplied.   Very sensitive control is provided by turning (pivoting) the friction wheel by means of an external force. The construction is simple and compact and, to obtain a sufficiently high contact force, the rolling elements are pressed inwards by springs. The designation "circular mechanism" was chosen because the motion of all the points which contribute to power transmission takes place on a circular path. See the more detailed description in the attached "description of the operation of the variable-speed mechanism" and in the patent claims.

Title: Process and device for determining the rate of flow of air
Inventor: SCHULTE ERASMUS DIPL PHYS DR
IPC: G01F1/698
Filed: 1987-03-02
Abstract: In order to determine the rate of flow of air with an electrically heated air rate of flow meter around which the air is flowing, a constant heating power is applied to it in a series circuit so that it assumes an overtemperature depending upon the respective rate of flow of air. By determining the voltage drop on the rate of air flow meter and the current flowing through it, its instantaneous resistance value is acquired, with which value the immediate temperature of the air rate of flow meter can be determined by means of a specified temperature/resistance characteristic. The ambient temperature is determined simultaneously and subtracted from the temperature of the air rate of flow meter. By means of the resulting overtemperature and a specified air rate of current/temperature characteristic for the air rate of flow meter, it is possible to determine the instantaneous air rate of current.

Title: Method and apparatus for the formation of rolled-wire and scrap coils
Inventor: KOCH GUENTER DIPL ING
IPC: B21C47/14
Filed: 1987-03-20
Abstract: The invention relates to a method and an apparatus for the formation of rolled-wire and scrap coils. It serves for the collection and distribution of acceptable and scrap turns in the coil collecting station of a wire (rod) rolling mill, the starting and end turns, which are not of acceptable quality, being cropped from the incoming strand of wire by means of a shear installed in the coil collecting station and carried away separately. According to the invention, the object is achieved by the fact that the acceptable turns and the scrap turns are cut off and separated by catching arms arranged in the downender and by a shear and are then fed to the delivery roller table and scrap bin by way of a lifting device and further devices connected to the bottom part of the three-part mandrel and to the scrap mandrels. The apparatus is constructed in such a way that there is a three-part mandrel, the bottom part of which supports and centres the central part of the mandrel, which, in turn, supports and centres the top part of the mandrel, in the downender. Arranged in the downender are catching arms which can be pivoted in four planes and lock the top and central parts of the mandrel, also holding the wire turns.

Title: Circulating-air extractor hood
Inventor: DIERL LUDWIG DIPL ING
IPC: F24C15/20
Filed: 1987-04-14
Abstract: The known circulating-air extractor hoods have the following deficiencies:     a) low circulating-air capture rate b) precipitation of exhaust-air constituents on the catching areas, entailing great cleaning problems   c) frequent filter replacement   d) high noise development and   e) large overall volume.  The invention has the intention of eliminating these deficiencies. The circulating-air extractor hood (100) is a built-under unit for a wall cupboard (200). It consists of a housing (130) and an extendable exhaust air-collecting device (120). Two jets (1, 2) convey the exhaust air to the inlet (134). In the adjoining wet-air filter (140), the exhaust-air impurities are separated off into the liquid by means of flow deviation and cooling. The cooling takes place in the wetted, lower filter element (147). During evaporation of the liquid, the flow cross-sections change; the wet-air filter is therefore mounted in a floating manner. Furthermore, the air flow passes into a rubber-mounted radial fan with large impeller (151). Thereafter, it flows to the air-collecting chamber (170) which distributes it and accommodates a lamp (172) which illuminates the cooking area through the bottom (171) of the air-collecting chamber. A partial flow passes into the open via the air shaft (210), the remainder via the slots (123, 132). The radial-fan housing, the air-collecting chamber and the air shaft are sound-damped. Cleaning of exhaust air in cooking areas. <IMAGE>

Title: Method for adjusting receiving antennas
Inventor: SCHAAF CHRISTOPH DIPL ING
IPC: H01Q1/12
Filed: 1987-07-13
Abstract: In order to adjust antennas for TV signals, the TV receiver is normally used as a test set, the object being to minimise the noise component of the received video signal. This type of adjustment is unsuitable for the reception of satellite signals by means of parabolic antennas, since fine adjustment of the antenna is too inaccurate as a result of the special type of signal coding (D2-MAC). Since the decoder module (52) which is used for D2-MAC decoders, has the designation DMA 2270 and is made by the Intermetall Company has an output, which is designated as the IM-Bus, for measuring the bit error rate of the audio signal, fine adjustment of the antenna can be carried out by minimising this bit error rate. <IMAGE>

Title: Radial-flow turbine and its inversion as a drive unit
Inventor: SCHROETER HEINRICH
IPC: F03B17/06
Filed: 1987-07-03
Abstract: The invention concerns a single-stage radial-flow turbine and its inversion. This turbine module consists of a rotor (drum rotor) with closed end faces and blades arranged on its periphery, whose inner sections are aligned towards the centre, end tangentially at the outer circumference, and describe a circular arc in between, and a stationary blade that is arranged centred in the rotor and able to revolve about the axis. By swivelling the guide blade up to 90@ from the effective direction of flow of the medium, the output is regulated in free flow. In order to convert even large pressure differences, the radial-flow turbine module can be integrated into a rectangular casing that ensures the medium is directed tangentially and allows a pipe to be connected. By inverting the radial-flow turbine module described, a drive unit is obtained with a thrust along the plane of the guide blade, i.e. perpendicular to the rotor axis. The drive of the guide blade and power transmission between the rotor and the generator (motor) can be effected peripherally or axially.
