Abstract: Method, system and apparatus are disclosed for invessel composting of organic material. A compost handling apparatus moves forwardly through a bed of composting material in an elongate open bay. Specifically, an agitator comprises feed means such as a transversely mounted cylindrical drum, which feeds composting material to a conveyor which lifts the material and projects it rearwardly behind the agitator. Regulator means, such as an adjustable deflector, controls the discharge of composting material by the conveyor. The deflector is adjusted as the agitator moves forward through the composting material to develop a level bed in the bay behind the agitator. Sensor means may be employed to generate a depth signal corresponding to the depth of the composting material for controlling the deflector.

Title: Standby power circuit arrangement
Inventor: BONNEVILLE MARC ETIENNE
IPC: H02J9/00
Filed: 1995-02-16
Granted: 1996-11-26
Abstract: A power supply circuit arrangement for electrical equipment, such as a loudspeaker with an integral power amplifier, which can be switched between an operational mode and a standby mode in response to a detected on/off signal, provides a desirable isolation of the main supply voltage from the detector. The arrangement comprises a transformer, having a primary winding and a secondary winding, and a switched impedance device between the transformer and the power supply input. The switched impedance device is switchable between high and low impedance states in response to the detected on/off signal. A control circuit for detecting the on/off signal and switching the variable impedance states is connected in common with a main circuit of the equipment to the secondary winding of the transformer, so that their respective supply voltages are both switched, in common, by switching of the impedance device. The control circuit and variable impedance device isolate the detector from the power supply. In the operational mode, the variable impedance is switched to its low impedance and the common voltage supplied to the main circuit and the control circuit is sufficient to operate both of them. In the standby mode, the variable impedance is high and the common voltage is inadequate for normal operation of the main circuit but adequate for normal operation of the control circuit.

Abstract: A method and apparatus are disclosed for measuring a resistance of a sensor. The apparatus injects a first test current into the sensor and then measures a substantially stable first voltage level across the sensor when the first test current is present. The apparatus then injects a second test current into the sensor, the second test current being substantially equal to but opposite in polarity to the first test current. A substantially stable second voltage level across the sensor is measured when the second test signal is present. Using the first measured voltage level and the second measured voltage level, the apparatus calculates the resistance of the sensor.

Abstract: Un moteur à embrayage (30) muni d'un rotor extérieur (32) et d'un rotor intérieur (34) tous deux rotatifs, et ayant à la fois une fonction de transmission directe et de régénération, est installé sur un arbre secondaire d'un moteur à explosion (50). La puissance du moteur à embrayage (30) est transmise aux roues avant (26, 28) via un arbre d'entraînement (22A). Un moteur auxiliaire (40) est accouplé directement à l'arbre d'entraînement (22B) de façon à transmettre la puissance aux roues arrière (27, 29). Le moteur à embrayage (30) peut régénérer une partie de l'énergie du moteur (50) par une rotation différentielle. Le couple peut être transmis aux deux arbres, par entraînement du moteur auxiliaire (40) par au moins une partie de l'énergie régénérée ou de l'énergie stockée dans une batterie (94); on obtient ainsi un entraînement des quatre roues. De plus, le moteur à embrayage (30) peut être surmultiplié lorsque le moteur auxiliaire (40) opère la régénération. Dans une configuration comportant un engrenage planétaire (120) et les moteurs (MG1 et MG2), au lieu de la configuration dans laquelle le moteur d'embrayage sert à répartir la puissance du moteur à explosion, la puissance est distribuée par l'engrenage planétaire (120), et la puissance est transmise à l'un des arbres par l'intermédiaire de la puissance de l'engrenage planétaire (120) et de l'autre arbre via le moteur (MG2); on obtient ainsi l'entraînement des quatre roues.

Abstract: An interface circuit transmits a binary logic signal by transmitting a pulse at a first potential at each falling transition of the binary logic signal, and a pulse at a second potential at each rising transition of the binary logic signal.  At other times, the output terminal of the driver circuit is placed in the high-impedance state.  The receiver circuit outputs a first logic level upon receiving a pulse at the first potential, and outputs a second logic level upon receiving a pulse at the second potential. Output of these logic levels is maintained until the next pulse is received.  The transmission line is preferably terminated at a potential intermediate between the first and second potentials.

Abstract: Cette invention se rapporte à des systèmes de nettoyage automatique pour piscines, tel qu'un appareil de nettoyage automatique (10) pour piscines, dans lequel sont incorporés un ou plusieurs ballets courbes (30) faisant saillie à partir de sa surface inférieure. Ces ballets (30) et le fond plat (34) de l'appareil de nettoyage (10) produisent un tourbillon à mesure que le fluide se dirige vers son admission centrale (50), le courant de fluide ainsi créé emportant avec lui les débris. Une gorge cannelée (102A) entourant l'admission (50) aide en outre l'intérieur de la base de l'appareil de nettoyage (10) à retenir les débris, lorsqu'il est ouvert à des fins de nettoyage, formant ainsi en plus une trajectoire de courant amélioré pour une collecte plus efficace des débris. Une valve (200) est également prévue pour réguler et indiquer le débit de fluide se dirigeant vers l'appareil de nettoyage (10). Dans cette valve (200) se trouve un plongeur (203) fixé à un ressort (202), dont la force s'oppose au courant de fluide traversant la valve (200). Un courant de fluide suffisant pour créer une force supérieure à la force du ressort (202) comprime celui-ci, ce qui entraîne toutefois un déplacement du plongeur (203) à l'intérieur du tube (201) et fournit une indication dynamique du débit de fluide. Un diffuseur (206) et des orifices (204A) de libération du fluide permettent un réglage de la valve (200) propre à produire le débit désiré.

Abstract: Dans un récepteur à modulation de fréquence (MF) pourvu d'un démodulateur qui réceptionne un signal radio et génère à partir de celui-ci un échantillon de phase dont le comportement détermine une sortie du démodulateur, un appareil permettant d'éliminer un signal d'interférence basse fréquence de l'échantillon de phase convertit l'échantillon de phase en un échantillon de fréquence qui subit ensuite un filtrage passe-haut afin de produire un échantillon de fréquence filtré. L'échantillon de fréquence filtré est ensuite converti en un échantillon de phase filtré, puis peut être démodulé selon des techniques connues. La conversion de l'échantillon de phase en un échantillon de fréquence peut être effectuée par un premier circuit de différenciation de service. La conversion de l'échantillon de fréquence filtré en échantillon de phase filtré peut être effectuée par un intégrateur. Du fait que le démodulateur peut donner une mauvaise qualité de fonctionnement lorsque l'appareil de l'invention est appliqué à un signal radio n'ayant pas d'interférence basse fréquence, selon un autre aspect de l'invention, le démodulateur est également pourvu d'un circuit servant à détecter la présence du signal d'interférence basse fréquence dans le signal radio, et à sélectionner alternativement, en réponse à celui-ci, soit l'échantillon de phase filtré, soit l'échantillon de phase d'origine à envoyer à d'autres circuits de démodulation. Plusieurs procédés de détection de la présence du signal d'interférence basse fréquence sont décrits.
