Title: Ameliorations apportees a des circuits electroniques de commande de servo-vanne
Inventor: MAUE DALE N
IPC: G01M7/02

Abstract: Circuit (110, 129, 143, 145) permettant d'obtenir une plus grande précision et une réponse totale du système pour des charges à impédance mécanique complexe, telles que des simulateurs de tremblement de terre et permettant notamment de compenser les limitations dans la commande du déplacement réel du boisseau de vanne (44A) et de le stabiliser et de le commander de manière adéquate à haute fréquence. Le circuit ci-décrit comprend un premier filtre d'état variable (110) permettant d'étendre la largeur de bande des fréquences d'actionnement de la servo-vanne par l'addition d'un signal principal de compensation des réactions hydrauliques de la servo-vanne. Le signal de sortie du premier circuit de filtre (110) est à son tour appliqué à une jonction de sommation (107) où l'on détermine le signal de réaction (17) de déplacement du boisseau et le signal de sortie de la jonction ou du circuit de sommation (107) est sommé (133) avec le signal de sortie d'un filtre supplémentaire (129) qui nettoie le signal en filtrant le bruit et qui assure que la phase des signaux stabilisateurs est correcte. Le signal d'entrée final (141) est ensuite appliqué à un système d'entraînement spécifique utilisant deux amplificateurs (143, 145) reliés sous la forme de pompes de courant pour mettre sous tension de manière indépendante les bobinages (60, 61) du moteur électrique entraînant le boisseau de vanne (44A) de manière à garantir un courant adéquat pour l'entraînement du boisseau (44A) dans des directions opposées à des fréquences élevées.

Abstract: In a device for the treatment of living beings and plants with pyramidal energy, the energy is picked up on energy pick-up lines (12, 13), which are arranged electrically separate along the four edges of the pyramid (6). Since the emission of energy is particularly strong along the pyramid edges, a particularly large amount of energy can be picked up by energy pick-up lines (12, 13) of this type. Such energy pick-up lines (12, 13) are considerably cheaper to produce. <IMAGE>

Abstract: A group control for an elevator system in which a call firmly assigned to a car, but not serviceable at a stop at the respective floor due to an expected overload, can be serviced subsequently by the same car. For this purpose first and second circuits, assigned to the floors, are provided. A selector scanning the floor and car call memories activates at every position the assigned first and second circuits, where the first circuit causes the car to pass the respective floor if an overload would be generated at a stop. The second circuits assigned to the upward and downward directions are linked to each other in such a manner that, on establishment of an overload, the scanning by the selector of the floor and car call memories assigned in each case to the calls of opposite direction is prevented. After passage of the non-serviceable floor and reaching of the point of return of the direction of travel, the car travels without interruption back to the earlier disregarded floor, whereby the blocking of the scanning of the floor and car call memories of the calls in the opposite direction is cancelled.

Abstract: It is known, in lye containers for washing machines or the like, to connect an end wall releasably to a basic body. The basic body and end wall, which can both be produced from sheet metal, have a first and a second shaped region, between which a receiving space for a sealing ring can be formed. A first and a second end portion adjoin the respective shaped regions. The basic body and end wall can be connected by screwing the two end portions together by means of tension rods. The end wall is stiffened as a result of the bearing of an annular compensating weight. The production of a connection of this type involves a high outlay. Because the two end portions (6, 7) are each made hollow- cylindrical and can be connected to one another via fastening screws (9) and/or clamping springs (35) distributed over the circumference, the basic body (1) and end wall (5) can be connected in a simple way. The lye container is suitable for use in washing machines, laundry dryers or the like. It can also be designed leakproof for heavy loads and can be easily assembled. <IMAGE>

Abstract: A solid state sensor (10), for sensing a physical parameter such as pressure, comprises a resonantly vibratable beam (18) formed across a cavity in a substrate (12) by micro-machining, and arranged such that changes in the parameter vary its resonant frequency. The beam (18) either consists of or has deposited on it a material exhibiting piezo-electric effect, so that vibration of the beam can be excited by using the effect. This is achieved using light (24), either by forming a photodiode in the substrate in or near the beam, so that illuminating the photodiode causes a voltage to be applied to the beam, or, in the case where the piezo-electric material exhibits surface piezo-electric effect, by directly illuminating the beam.

IPC: G01R15/20
Filed: 1988-02-12
Abstract: A contactor utilizes a non-saturating current transducer for sensing the mount of current flowing in the electrical conductor connected to the contactor. The current sensor is toroidal with a predetermined air gap therein which increases the reluctance of the magnetic circuit. This increased reluctance allows the secondary of the transducer to produce a voltage which is proportional to the derivative of the primary current, that is the current being sensed by the transducer. The aforementioned voltage is linearly proportional to the derivative of the current over a wide range of primary current values. This voltage is integrated to produce an output signal which is directly proportional to the primary current over the wide range of current values. By measuring only the derivative of the primary current, the current transducer can be significantly smaller than an equivalent current transformer. The core may be separated in two places to form two semi-circular cores one of which may be moved relative to the other to vary the size of the air gaps.

Abstract: A contactor utilizes a non-saturating current transformer for sensing the amount of current flowing in the electrical conductor connected to the contactor. The current sensor is made of homogeneous sintered powdered metal having evenly distributed microscopic air gaps therein which increase the reluctance of the magnetic circuit but resist the influence of stray magnetic flux. This increased reluctance prevents magnetic saturation over a wide range of input current and allows the secondary of the transducer to produce a voltage which is proportional to the derivative of the primary current, that is the current being sensed by the transducer. The aforementioned voltage is linearly proportional to the derivative of the current over a wide range of primary current values. This voltage is integrated to produce an output signal which is directly proportional to the aforementioned primary current over the wide range of current values.

Abstract: The invention relates to a fireproof rolling door providing quick balanced opening/closing, which makes it possible to close or to separate openings for passage to the outside either in premises or buildings subject to fire risk where there is heavy traffic, and to losses of heat or cold, and to draughts. The device consists of a self-supporting frame (1) supporting a drum (2) with motorised rolling (3) on which is fitted a curtain (6) stretched by means of a system with straps (7) which is separate from a system for balancing the said curtain (6). A fireproofing treatment of the curtain (6) and of the straps (7) and a quick operating speed enable it to be used in complete safety. An electronic limit-of-travel system (4) with adjustable thresholds makes it possible to respond to this quick operation. This device will thus be of use principally in manufacturing and storage workshops, processing workshops, supermarkets, car parks, and buildings supplying merchandise and where there is heavy traffic. <IMAGE>
