Title: Hydraulic control arrangement
Inventor: OLBRICH GOTTFRIED DIPL ING
IPC: F15B11/16
Filed: 1986-08-29
Abstract: A hydraulic control arrangement (10) with a first working circuit (11) of load-pressure-sensing directional control valves (31, 32) and a second control circuit (12) is proposed in which the distribution of the flows from a pump (13) to the two working circuits (11, 12) is controlled by a choke valve (15) working as a pressure balance. The choke valve (15) lies in a connection from the pump connection (16) to the run-on connection (21), to which the second working circuit (12) is attached in tandem, the flow resistance of which keeps the choke valve (15) open in the neutral position of the control circuits (11, 12). A priority working circuit (11) having load-pressure-sensing directional control valves (31, 32) in a type of construction for closed circulation can be combined with a secondary working circuit (12) in such a way that energy losses are kept low and versatile adaptations are possible. <IMAGE>

Title: Device for limiting wheel slip
Inventor: FRIEDOW MICHAEL
IPC: B60T8/48
Filed: 1987-09-15
Abstract: The proposed device (2) for limiting wheel slip on a left-hand and a right-hand drive wheel of a vehicle axle comprises two brake pressure generators (3, 4), which can be actuated alternately by a solenoid drive (5). For this purpose, the two brake pressure generators (3, 4) are arranged coaxially with and laterally inverted in relation to the said drive (5) and are hydraulically connected to wheel brakes of the drive wheels. The solenoid drive (5) has two working directions and two coaxially aligned pushrods (21, 22), which are directed towards pistons (14) of the two brake pressure generators (3, 4). A control module (12) determines by observation of wheel rotation sensors (8, 9, 25, 26) whether undesirable wheel slip occurs on the left-hand or right-hand drive wheel. The control module (12) then controls the solenoid drive (5) so that brake pressure is fed into a wheel brake (6, 7) assigned to the wheel driven with excess torque in order to deplete the excess drive torque. The device (2) of space-saving design can easily be accommodated in vehicles. <IMAGE>

Title: Modulo-10 counter for both counting directions
Inventor: MERKLE PAUL
IPC: H03K23/56
Filed: 1987-12-31
Abstract: The decades of the forwards-backwards counter according to the subject of the invention differ from the decades of the forwards-backwards counter according to P 3743497.7 mainly in that two-path main circuits, which only have four counting flipflops each, are used. The decades of this forwards-backwards counter consist of decades according to P 3743496.9, which are each combined with a supplementary circuit (60). This forwards-backwards counter is also not a genuine forwards-backwards counter, because the counter state changes by switching from forwards to backwards or by switching from backwards to forwards. <IMAGE>
Patent DE-3800222-A1 (DE)
Title: Microphone protected against acoustic feedback
Inventor: RIEDER JOACHIM
IPC: H04R3/00
Filed: 1988-01-07
Abstract: If microphones are used for direct sound amplification, the problem of acoustic feedback almost always occurs. This manifests itself in a loud whistle. Echoes after loud tones are also attributable to this. Filtering out this whistling tone simultaneously also suppresses the tone which is to be amplified. In most cases, however, the acoustic feedback then occurs at a different frequency. There is then only one possibility, which is to reduce the sensitivity of the microphone. The singer or speaker must then sing or speak very loudly into the microphone directly in front of his mouth. Naturally, this leads to changes in the sound pattern. The invention deals with the design of a microphone which suppresses acoustic feedback by electric means. This makes it possible to speak into the microphone from a distance of 10-50 cm without acoustic feedback occurring even with a high volume of the loudspeaker. Nor does the microphone need to exhibit an extreme directional effect, which is highly desirable for natural reproduction.
