Abstract: Cette invention concerne des dispositifs de localisation des dérangements sur les lignes de transport d'énergie, qui utilisent des combinaisons de signaux transitoires transmis par conduction et de signaux électromagnétiques transmis par rayonnement, produits soit par l'arc d'un entrefer soit par une décharge orageuse, ainsi que la connaissance du chemin spécifique des lignes de transport d'énergie associées au dérangement. L'instant d'arrivée des signaux transitoires transmis par conduction et générés par le dérangement est repéré par un capteur d'enregistrement des dérangements (FRS). L'instant d'arrivée du rayonnement électromagnétique de bas niveau (VHF/UHF) généré par la formation d'arcs électriques associés aux dérangements sur les lignes de transport d'énergie est repéré par au moins un capteur de détection d'arcs (ADS), localisé à quelque distance de la ligne de transport d'énergie. Les deux capteurs conçus pour repérer les instants d'arrivée des signaux transmis par conduction et par radiation transmettent des données à un analyseur central (PLFLA) de localisation des dérangements des lignes de transport qui reçoit et manipule ces données pour localiser le dérangement sur la ligne.

Abstract: A valve assembly and method for controlling the flow of fluid through a conduit in which a ball valve is disposed in the conduit and is provided with a through bore for receiving the fluid.  An insert is also disposed in the conduit downstream of the ball valve and has a plurality of relatively small flow passages.  A relatively large flow passage is defined by that portion of the conduit not occupied by the insert.  The valve is rotatable in the conduit to direct the fluid from its bore through one or more of the flow passages and a portion of the insert forms an airfoil surface to prevent separation of the fluid as it passes through the relatively large flow passage.

Abstract: A centering arrangement for controlling relative movement between a series of mold support plates in a stack mold having three or more levels. The centering arrangement uses a plurality of centering devices which are substantially identical, each spanning two mold levels and being connected to three adjacent mold support plates. Each centering device has a shaft generally parallel to an axis of the mold and having an intermediate portion journalled in an intermediate connector to allow rotational movement about a shaft axis, but to restrain relative axial movement between the shaft and the intermediate connector. Helical splines extend from the intermediate portion toward opposite ends of the shaft in oppositely twisting helices. End connectors having cooperating splines engage the splined portions of the shaft and connect the centering device to the outermost of the mold plates to which it is connected. The intermediate connector secures the centering device to the intermediate of the three mold plates to which the centering device is connected. Relative axial movement between the end connectors and the adjacent intermediate connector requires simultaneous translation and rotation of the shaft in equal amounts in both end connectors, thereby maintaining the intermediate connector centered between the two adjacent end connectors.

Abstract: A system and process are provided for converting a light hydrocarbon gas to a synthetic heavier hydrocarbon liquid. The system includes an autothermal reformer, a Fischer-Tropsch reactor and a Brayton cycle that are structurally and functionally integrated. In the practice of the process, a mixture of a hydrocarbon feed gas, a compressed air feed and process steam is fed to the autothermal reformer to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The tail gas is heated and fed with compressed air and steam to the Brayton cycle having a combustor and a series of power turbines and compressors. The tail gas and air feed are burned in the combustor to produce a combustion gas that is used to drive a power turbine linked by a shaft to an air compressor, thereby driving the air compressor. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the autothermal reformer. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon feed gas before it is fed to the autothermal reformer, preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor and preheat the tail gas before it is fed to the combustor.

Abstract: A multiple sensing technology-based occupancy sensor. Ultrasonic and infrared sensors are used to produce first and second occupancy estimator signals that are combined using a fusion based detection algorithm to produce a combined estimator signal. The combined estimator is then used to switch electrical loads when the combined estimator signal is above a predetermined threshold. The result is an occupancy sensor that has a very high probability of occupancy detection and a low probability of false tripping. In addition, infrared sensitivity is adjusted based upon an estimation of the background noise in order to minimize the occurrence of false tripping.

Title: Regulating device for an adjustable hydraulic pump with several consumers
Inventor: VAN BRACHT DETLEF
IPC: F04B49/08
Filed: 1998-09-24
Granted: 2007-11-20
Abstract: The invention relates to a regulating device for an adjustable hydraulic pump (1). Said device has a delivery flow control valve (15) and an output control valve (27). The delivery flow control valve (15) is subjected to the pressure difference between a first control line (18b) which is connected to the delivery line (5b) downstream of a metering throttle (6b), and a second control line (19) which is connected to the delivery line (5b) upstream of the metering throttle (6b). The delivery flow control valve (15) then regulates the adjusting pressure for an adjusting device (7) according to this pressure difference in order to adjust the delivery volume of the hydraulic pump (1). The output control valve (27) is situated between the first control line (18b) and a pressure medium tank (4). The control pressure in the first control line (18b) acts upon the output control valve (27) in the direction of opening and the adjusting device (7) acts upon the output control valve (27) by means of a spring measurement device (29) in the direction of closing. According to the invention, several consumers, each connected to the hydraulic pump (1) by a separate delivery line (5a-d) in which an adjustable metering throttle is located, can be controlled by the regulating device. A first control line (18a-18d) is connected to the delivery line leading to the designated consumer upstream of the designated metering throttle (6a-6d). A first pressure change device (17, 40, 41) selects the highest of the control pressures in the first lines (18a-18d) and conveys this to the delivery flow control valve (15). The output control valve (27) is only connected to the first control lines (18b, 18d) of the selected, output-controlled consumers, the first control lines (18a, 18c) of the remaining, non output-controlled consumers being separated from the output control valve (27).
