Patent DE-3429326-A1 (DE)
IPC: G01F1/10
Filed: 1984-08-09
Abstract: In this device, three electrodes (3, 4, 5) are arranged adjacently to one another at a distance in a flowing fluid. During its rotation, the vane wheel moves with one edge of its vanes closely past the electrodes (3, 4, 5) to which complementary pulses of an alternating voltage are applied by means of a pulse generator (8) for measuring the impedance of the fluid in an electrical analysing circuit which comprises a synchronous demodulator which is clocked by the alternating voltage (Us) of a short-time pulse transmitter (12) which, in turn, is driven by the pulse generator (8). To form a dynamic voltage divider, the centre electrode (4) is connected to a load resistor (R7) with respect to ground, across which a varying measurement voltage (U4) is picked up. This voltage is applied to a gate circuit (14), the enabling time of which is controlled by the short-time synchronising/demodulation signal (Us) and which is short compared with the duration of the pulses of the alternating voltage at the outer two electrodes (3, 5). <IMAGE>

Patent DE-3447980-A1 (DE)
Title: Electronically commutated DC motor for driving rotating storage media
Inventor: RABE ERICH
IPC: H02K3/26
Filed: 1984-09-13
Abstract: The rotor of an electronically commutated DC motor has at least one permanent magnet having at least four poles, which are arranged concentrically with respect to the rotor rotation axis, are polarised essentially at right angles to the rotation axis, and are arranged adjacent to an annular magnetic return path part. The stator winding, which is accommodated in the annular gap between the rotor and the magnetic return path part, has a meandering conductor-track arrangement whose straight meander sections running to and fro consist of a number of parallel conductor sections. A device which detects the angular position of the rotor with respect to the straight meander sections running to and fro supplies signals to a drive electronics device which, for its part, controls the current flow through the conductor-track arrangement such that, in consequence, said arrangement produces a magnetic field which drives the rotor. Fitted firmly to the rotor is a bearing flange whose flange plane can be set to a few micrometres precisely with respect to a motor reference plane. A DC motor which is constructed in such a manner, is electronically commutated and has, for example, 40 poles, has an extremely constant rated motor rotation speed and, because of the high space factor in the magnetic gap, produces a high e.m.f. Such a motor can preferably be used as a drive unit in Winchester-disk stores.

Patent DE-3507683-A1 (DE)
Inventor: AICHELE WILFRIED DR
IPC: F02F7/00
Filed: 1985-03-05
Abstract: A cup tappet with a hydraulic adjustment component, which can be used in the valve drives of combustion engines. The cup tappet consists basically of a short staple-reinforced duroplastic or thermoplastic synthetic resin mass with a bottom plate on the cam side of higher hardness and tenacity. The oil supply of the hydraulic adjustment component (5, 6) is effected either through the cam by means of a bore hole (10) in the bottom plate (4), or by means of small diameter steel tubes (19) which are glued or pressed into corresponding bore holes in the casting (1). The mass of the cup tappet is considerably less than that of conventional cup tappets made of steel. It therefore permits higher RPM's and shorter valve control times and, as a result, greater motor efficiency.

Patent DE-3515565-A1 (DE)
Title: Change-over valve arrangement for combined water meters
Inventor: DEWALD FRITZ
IPC: G01F7/00
Filed: 1985-04-30
Abstract: The change-over valve arrangement serves to change over the flow automatically from the secondary meter to the main meter and comprises a main valve for the main-meter flow and a smaller relief valve for making available an additional effective surface. In the closed position the valve closure element rests by its larger sealing ring against the main-valve seat and by its smaller sealing ring against the relief-valve seat. The sealing rings for the main valve and for the relief valve are flexible flat packing rings which bear freely movable sealing lips on the side facing the respective sealing seat. The closure element has a dish-like orifice plate which can be inserted into a constriction in the fixed outer part of the valve, in front of which the water of the secondary meter flows in. To achieve a rapid opening and closing movement, the length of the movable sealing lips and the two flat packing rings is so designed that, during the valve opening phase, they come away from their respective sealing seat only when the dish-like orifice plate has reached the inlet to the retaining stage.

Title: Device for controlling the fuel-air mixture of an internal combustion engine
Inventor: HIERETH HERMANN DR ING
IPC: F02P5/15
Filed: 1985-05-31
Abstract: A device for controlling the fuel-air mixture of an internal combustion engine with a throttle valve in the air intake system and at least one electronically actuated injection valve for the injection of fuel into the intake pipe comprises a measuring sensor for sensing the position of the throttle valve and generating a corresponding electrical signal and further measuring sensors for the detection of operating parameters of the internal combustion engine, from the electrical output signals of which the operating state of the internal combustion engine is determined in an electronic control device. In the control device lambda values are predetermined for each operating state, which values are converted by this device into corresponding signals for controlling the opening time of the injection valve and the ignition timing of the ignition system. In order, in transient flow operation of the internal combustion engine, to operate the latter with an excess air ratio lambda, in which a higher torque is set whilst adhering to the predetermined exhaust emission values, a control signal is formed in the control device from a signal of the speed measuring sensor and a signal of the throttle valve measuring sensor from a predetermined throttle valve opening angle onwards, by means of which control signal the opening time of the injection valve is determined and the ignition position is shifted to a >>retarded<< ignition point in a direction appropriate to the lambda value.

Title: Circuit for connecting two primary or secondary connection lines and the telephone sets assigned to them
Inventor: WEBER MANFRED NORBERT
IPC: H04M1/00
Filed: 1985-08-28
Abstract: The invention relates to a circuit for reciprocal pick-up of two subscriber connection lines. This circuit allows both connection lines to be answered by both telephone sets. A call arriving on the subscriber's own connection line on his own telephone set is signalled during answering on the other connection line. However, each incoming call is signalled only on the assigned telephone station. If this telephone station is unattended, the subscriber on the other telephone station can pick up this call. The circuit allows the call to be transferred back to the called telephone station. In the case of outgoing calls, both telephone sets operate independently of one another, dialling-out from one telephone station via the line of the other telephone station being prevented by the circuit. The circuit is powered from the exchange line or the extension line.
