Abstract: A geosynchronous, multi-beam phased array satellite system (20) transmits to and receives from the earth radio frequency signals. The satellite system (20) has transmit (28) and receive phased arrays (29), beamformers (26 and 27), switch matrices (24 and 25), a switch controller (23) and a communications payload (22). The beam coverage of the phased array satellite system (20) is reconfigurable while the satellite (20) is its geosynchronous orbit. The geosynchronous multi-beam phased-array satellite system (20) provides a more cost effective and weight effective way of providing communications for geosynchronous satellite applications.

Abstract: A gas burner having a flame keeper cell and a sensor positioned in the flame keeper cell to assure that a no flame signal is sent to the control system for the burner only when the burner flame is completely extinguished. During initial lighting of the burner or after the burner flame is completely extinguished, the control system attempts ignition only a limited number of times or during a limited time period and then the flow of gas to the burner is stopped thereby presenting excessive gas discharge into the atmosphere.

Abstract: A piezoelectric fluid control valve includes an upper metering element (100) and a lower metering element (116). Each metering element (100, 116) has an anchored end affixed to the walls of a chamber (16). The anchored end of the upper metering element (100) is provided with an inlet channel (122) and that of the lower metering element (116) with an outlet channel (123). A metering orifice (124, 126) is provided within each metering element (100, 116). A cantilevered spring valve (128, 130) is positionable within the associated metering orifice (124, 126). Each cantilevered spring valve (128, 130) is continuously displaceable between an opened position and a normally closed position. Each one of the cantilevered spring valves (128, 130) has sharp metering edges (131, 133) that cooperate with the metering elements (100, 116) to provide the associated metering orifices (124, 126), the edges (131, 133) blocking fluid when the cantilevered spring valves (128, 130) are closed. Positioned between the cantilevered spring valves (128, 130) is a polymorph (132) which is in operative communication with the metering elements (110, 116). When a potential difference is applied, the polymorph (132) becomes deflected and opens one of the cantilevered spring valves (128, 130). Each cantilevered spring valve (128, 130) has three sides so that each valve (128, 130) effectively acts as a single piece flapper.

Abstract: Un élément émetteur-récepteur agit sur la phase d'un signal micro-onde qui le traverse. L'élément émetteur-récepteur comprend une pluralité de moyens commutateurs agencés de façon à diriger un signal de fréquence micro-onde fourni par un système radar, à travers un déphaseur non-réciproque à un réseau d'antennes en phase pendant le mode de transmission, et à diriger un signal de fréquence micro-onde reçu par le réseau d'antennes en phase au système radar, à travers le déphaseur non-réciproque, pendant le mode de réception. Le signal de fréquence micro-onde traverse le déphaseur dans le même sens, aussi bien pendant le mode de transmission que pendant le mode de réception. Un ensemble de signaux de commande est fourni à ces moyens commutateurs et au déphaseur de l'élément émetteur-récepteur afin d'obtenir des rayons dirigés et alignés d'énergie à micro-onde pendant les modes de transmission et de réception.
