  • Patent number: 7166218
    Abstract: The present invention relates to a device for separating an effluent comprising phases of different density and conductivity, the device comprising a pair of electrodes (12, 13), means (10) for introducing the effluent between said electrodes, means intended for separation (3) and discharge (4) of said separated phases. The separation means comprise at least one centrifugation element including a helical channel (19) in which the effluent is centrifuged after passing between the electrodes. An opening extends over the entire periphery of said centrifuged effluent so as to discharge part of the centrifuged effluent. The discharge means further comprise sealing means for limiting discharge of the less dense phase through said opening.

  • Patent number: 6047676
    Abstract: A device and method for assisting cold start of automobiles with internal combustion engines which include a cooling circuit and an exhaust line with a catalyst. The method includes use of at least one burner and a means for recovering the calories produced by the burner, where the calories recovered are restored to at least one of the following elements: the intake air, the walls of the engine itself, the internal cooling circuit of the engine, or the passenger compartment heating means. A burner is used directly to heat a gas-liquid exchanger built into cooling circuit of engine, as well as the engine exhaust gases. The intake air and vehicle passenger compartment thus benefit from the improved heating of the cooling circuit.

  • Patent number: 5844463
    Abstract: The present invention relates to a process for regulating the temperature of a fluid circuit comprising a thermostatic valve, which consists in maintaining a leak rate through the valve once the valve has been opened a first time in order to eliminate the temperature fluctuations of the fluid around a regulation temperature. Two thermodilatable elements with different expansion temperature thresholds are used. The invention further relates to a thermostatic valve intended to regulate the temperature of a fluid around at least one value and comprising at least a first thermodilatable element. The valve further includes a second thermodilatable element for maintaining a controlled leak rate as soon as the valve has been opened (a first time).
