Patent DE-4135335-A1 (DE)
Inventor: TRIEBEL SIEGBERT DIPL ING
IPC: H03H17/06
Filed: 1991-10-26
Abstract: To generate in-phase and quadrature components for digital signals, a Hilbert transformer for phase shifting by 90 DEG  and a delay element for equalising the signal transit time of the Hilbert transformer are normally used. The usable bandwidth is limited by the fact that the Hilbert transformer has nulls in the frequency response of absolute amounts at frequency 0 Hz and at multiples of half the sampling frequency. In the device according to the present invention, these nulls are avoided since symmetric filters with a phase shift of 45 DEG  and -45 DEG , respectively, are used for generating two signals in a quadrature phase relationship, which results in a reduced complexity of implementation whilst retaining the same bandwidth. <IMAGE>

Patent DE-4208500-A1 (DE)
Inventor: KLEINMICHEL KLAUS
IPC: B05B9/03
Filed: 1992-03-17
Abstract: The spraying apparatus includes a medium-outlet nozzle with conical outlet opening and also an annular air nozzle and a plurality of horn-shaped air nozzles arranged opposite each other and directed obliquely inwards towards the emerging jet of medium. The spraying apparatus operates in a high-pressure process at about 70 to 300 bar if an application jet of large surface area is to be discharged, the compressed air delivery being switched off in this operating state. If the jet of medium is to be constricted, the hydraulic volumetric feeder intended for supplying the medium reduces the medium pressure to about 10 to 70 bar, the compressed air supply being switched on at the same time. The compressed air delivery from the annular air nozzle and the horn-shaped air nozzles is set by means of air control valves in such a way that the jet of medium takes on the desired geometry. With a control unit, the parameters can be externally entered and monitored. <IMAGE>

Patent DE-4218516-A1 (DE)
Inventor: FAHRENBERG PETER
IPC: B61L1/18
Filed: 1992-06-02
Abstract: The invention relates to a central supply device for a track circuit, in which device the signalling lines (4 and 5) of a connecting cable, laid on one side of the track, of a transmitter (3) which supplies the monitoring signal are connected approximately in the centre of a track section to be monitored, parallel to a potential-compensating connector (8) which is arranged at this point and consists of two loops (9 and 10) which extend spatially on both sides of the connection point (6, 7) and are connected to one another in the form of a figure eight. The feed power necessary for the monitoring signal can be substantially reduced in that the one signalling line (4) which is connected to the rail (1) which lies further away from the connecting cable of the transmitter (3) is laid outside the intersection point of the figure eight connection of the two loops (9 and 10) parallel to the one loop (9), the side length of the said loop (9) which extends parallel to the rails (1 and 2) being dimensioned, because of the coupling to the one signalling line (4), in such a way that the sum formed of the inductance and mutual inductance of both loops (9 and 10) is of identical magnitude. <IMAGE>

Title: Controlling output temp. of electrically heated through-flow water heater - deriving required heating power from through-flow channel input and output temperatures, instantaneous heating power, throughput, and defined output temp.
Inventor: TAAG JUERGEN
IPC: F24H9/20
Filed: 1992-09-09
Abstract: The method of controlling the output temperature of the water heater involves using temp. sensors (3,6) at the input and output of a throughflow channel(5), a throughput sensor (4) and a controller (12). The controller derives the required heating power from the throughput, input and output temp., instantaneous heating power and defined output temp. and feeds the required heating power to the heating body. A measurement error in the throughput sensor is detected automatically, stored and taken into account during subsequent adjustment of the instantaneous heating power. It is finally stored again self-adaptively. ADVANTAGE - Throughput meter errors are eliminated and water heated to required temp. is provided very quickly.

Title: Joint fitting for motor vehicle seat - has contact pressure bar, lifted off ratchet to move ratchet release lever into release position
Inventor: BERGHAUS KLAUS
IPC: B60N2/22
Filed: 1992-10-17
