Patent DE-3306950-A1 (DE)
Title: Heating water heat accumulator for a central heating installation
Inventor: RAHTK HARTWIG DIPL ING
IPC: F24D11/00
Filed: 1983-02-28
Abstract: A pressure boiler used as heat accumulator for heating water which is under pressure and can be heated to over 100 DEG C is connected to a heat exchanger which is arranged outside the boiler and in which the stored heat is given off to a secondary circuit.

Patent DE-3309770-A1 (DE)
Title: Process for metering, measuring and blending dry materials and liquid materials in the production of feedstuffs
Inventor: TRAUTMANN EBERHARD
IPC: B01F15/04
Filed: 1983-03-18
Abstract: The invention relates to a process for producing feedstuffs by blending feedstuff ingredients, in which the ingredients are continuously or discontinuously metered and measured from storage vessels via conveying equipment and sensors which determine the flow rates accomplished. The dry materials are premixed to give the so-called carrier material. One or more liquid materials are then mixed into this. Set points for the throughput rates of each individual ingredient prior to passing to a high speed mixer are set on set point adjusters. Furthermore, measured values of the ingredients just passed to the mixer are determined by the sensors. If a mutual deviation of the measured values and set points is established during a continuous set point/measured value comparison, then control signals and/or difference signals are formed from the deviations between the measured values and set points. If required, fault signals are produced from the difference signals.

Title: Power-assisted control device for gear shift clutches in motor vehicles
Inventor: LANDSTORFER KURT DIPL ING
IPC: F16D48/02
Filed: 1983-11-23
Abstract: In the case of a power-assisted control device (1) for gear shift clutches in motor vehicles a pressure medium source (2) is connected by way of branch pipe connections (4, 5, 6, 7) to a gear cylinder (3), which in turn is mechanically connected to the gear shift clutch. A 4/2-way reversing valve (9), by means of which the front and rear chambers (10 and 11) of the control piston (12) of the gear cylinder (3) can be pressurised and vented, is assigned to the output side of the pressure medium source (2) and a manually operatable is assigned to the output side of the latter 3/2-way valve (8) with a through flow position. The 3/2-way valve (8) contains a venting connection (13) to the atmosphere. In operation of the power-assisted control device (1) the two-position reversing valve (9) can be manually preset to one of the two positions. If the 3/2-way valve (8) is then manually switched through against the force of a spring, compressed air passes from the pressure medium source (2) either to the front chamber (10) or the rear chamber (11) of the two-position gear cylinder (3) in order to shift the gear shift clutch, the other chamber - rear chamber (11) or front chamber (10) - of the gear cylinder (3) respectively being vented. The control piston (12) of the gear cylinder (3) can be connected to a cam (14), which in at least one of the two control positions operates a switch (15) of an optical or acoustic display (16). <IMAGE>

Title: Circuit arrangement for telephone systems with transmission of AC signals
Inventor: KOEPSEL MANFRED
IPC: H04Q1/446
Filed: 1984-03-23
Abstract: The invention relates to a circuit arrangement for telephone systems with AC signals which can be transmitted to set up connection paths via speech lines, the AC signals being generated from an AC voltage whose mark-space ratio can be controlled according to the number of dial pulses to be transmitted. By means of the half-waves generated from the AC voltage (WSP), an oscillation packet control device (SPS) in each case switches on and off a first indicator relay (A) and a second indicator relay (B) which forward the AC voltage (WSP) in pulses to the speech lines (a and b) by means of their normally open switching contacts (a1, a2 or b1, b2) so that AC signals can be transmitted in pulses via a trunk circuit repeating coil (FLU). Circuit arrangements of this type are used in four-wire direct dialling-in central stations. <IMAGE>

Title: Control system for motor vehicles
Inventor: BAUER HEINRICH ING GRAD
IPC: G08G1/07
Filed: 1984-04-30
Abstract: In order to provide a means for motor vehicle drivers for testing whether, in the case of multi-lane carriageways with on-coming traffic, in particular motorways, the vehicle of the said driver is located in the correct lane in terms of the direction of travel, a receiver is provided in the vehicle, preferably in the driver's cab, which receiver triggers a visual and/or audible warning signal, in conjunction with a transmitter set up at each entrance to a multi-lane carriageway, when the vehicle drives on the wrong lane reserved for on-coming traffic. The functional interaction of the transmitter with the receiver is possible by virtue of the fact that both the transmitting frequency and the receiving frequency are identical. The display is connected here with a time relay by means of which signals which can be perceived visually and/or audibly remain switched on by the display device until the said device is switched off manually by the driver. <IMAGE>
