IPC: H03H11/46
Filed: 1993-06-29
Abstract: PCT No. PCT/DE94/00734 Sec. 371 Date May 15, 1995 Sec. 102(e) Date May 15, 1995 PCT Filed Jun. 28, 1994 PCT Pub. No. WO95/01671 PCT Pub. Date Jan. 12, 1995A circuitry arrangement for a resonant circuit that may be completely monolithically integrated and electrically tuned has a differential amplifier stage with two transistors T1,T1' fed by a constant current source I0 that are differentially loaded at their collectors by a voltage-dependent capacity and inductively loaded in relation to the circuit ground by a pair of emitter followers T2,T2' with electrically adjustable impedance that act upon the base. To implement the electrically adjustable impedances, transistors with associated resistances are provided (for example a pair of emitter followers T3,T3' with base pre-resistances R1,R1') which may be adjusted by control currents (for example I1I1') . The voltage-dependant capacity is implemented by transistors T4,T4' whose short-circuited emitters and collectors are connected so that the circuit node thus obtained is applied to the circuit ground through a voltage source U1. This circuit arrangement may also be used in a controllable oscillator by interconnecting two resonant circuits in a loop. The output signal of the first resonant circuit is used to control the second resonant circuit and the output signal of the second resonant circuit is inverted and used to control the first resonant circuit. Thus, two signals may be tapped at the outputs of both resonant circuits. The frequency of said signals may be varied by a control voltage and their frequency-independent phase difference equals  pi /2. An advantageous implementation of such an oscillator is obtained by decoupling the output signals of both resonant circuits through two identical output drive stages.

Title: Actuator, in particular for heating, ventilating or air-conditioning flaps and method for the production thereof
Inventor: BERNREUTHER GEORG
IPC: B60H1/00
Filed: 1993-07-24
Abstract: The invention relates to an actuator for heating, ventilating or air-conditioning flaps (dampers) in motor vehicles and to a method for the production thereof, the actuator comprising a gear housing, an electric motor mounted therein, a step-down gear acted upon by the torque of the electric motor, an output shaft and a position-determining device connected thereto. In the case of conventional position-determining devices for actuating elements adjustment takes place by frictional engagement and therefore precise adjustment is only possible with difficulty and, in addition, its lasting retention is not ensured. The object of the invention is therefore to provide a means of adjusting the position-determining unit with respect to the output shaft in as precise a way as possible and then to fix it in position rapidly and to lasting effect. This is achieved, according to the invention, in that a grinder carrier is provided on its periphery with a toothed portion with which an adjusting tool can be brought into engagement for the purpose of adjustment and that, furthermore, fixing regions are provided in the grinder carrier and in the output gearwheel, which regions permit the grinder carrier to be connected frictionally to the output gearwheel by means of a rapidly curable compound without, in the process, damaging the gear. <IMAGE>

Title: Cable, in particular an optical overhead cable, and a method for producing the same
Inventor: HELLE WERNER DIPL ING DR
IPC: H01B5/10
Filed: 1993-09-29
Abstract: A cable (10), in particular an optical overhead cable, and a method for producing the same. Optical cables (10) are known in which optical conductors (optical fibres) (19) are arranged in an enveloping tube (18) made of steel. Electrical conductors (17) which are likewise arranged in the cable (10) are made of aluminium, tensile-stress absorbing supporting wires (16) being made of steel. As consequence of the different material properties, a considerable potential difference is formed in the cable (10), which leads to corrosion of the steel. This has an adverse effect on the tensile stength of the cable (10), on the one hand, while on the other hand adverse effects on the transmission performance of the optical conductors (19) can be found. In the cable (10) according to the invention, the enveloping tube (18), the supporting wires (16) and the conductors (17) are composed, at least on their outer surfaces, of a material whose normal potential is similar. In consequence, the corrosion of the steel is prevented. The cable (10) is characterised by a longer life. A cable (10) which is formed in this way is preferably used as an overhead line cable for power and information transmission. <IMAGE>

Title: Cycled power supply for lamps from AC mains or DC source e.g. car battery
Inventor: LECHELER REINHARD
IPC: H05B41/282
Filed: 1994-05-30
Abstract: The invention concerns an interference-control circuit for switching power supplies suitable for use in the operation of both discharge and incandescent lamps. The interference-control circuit has at least one controlled auxiliary supply (ZW, F) plus a control circuit (TR1). The auxiliairy supply/supplies (ZW, F) generate controlled compensation signals which are inverted with respect to the interference signals caused by the fast switching transistors (T1, T2). The auxiliairy supply (ZW, F) is connected either parallel to the source of interference and capacitively to the environment or in series with the source of interference and galvanically into the supply leads. In the first case, the auxiliairy supply preferably includes, near the switch (T1, T2), a metal surface (F) whose potential variations are inverted with respect to those of the source of interference essentially round the junction point (M) between the switching transistors (T1, T2) e.g. by means of the transformer (TR1). In the second case, the auxiliairy supplies are preferably formed by two secondary coils of a transformer. The primary coil is controlled by the potential changes in the source of interference and induces in the leads of the secondary coil an opposite phase common-mode compensation signal. Optionally, the interference-suppression circuit can be designed as a closed control circuit, the common-mode interference current in the leads being used as the regulating variable.
