Title: Downhole flow rate controle device
Inventor: RAYSSIGUIER CHRISTOPHE
IPC: E21B34/06
Filed: 2000-02-25
Abstract: A flow rate control device (18) placed down an oil well in production comprises holes (24) formed in the production tubing (16), a closure sleeve (26) suitable for sliding facing the holes (24), an actuator (31) disposed eccentrically relative to the tubing (16), and an intermediate part (29). The intermediate part (29) is guided out the tubing (16) in a manner such as to withstand the tilting torque due to the eccentricity of the actuator (31). A coupling (46) that is flexible except in the direction in which the sleeve is moved connects the part (29) to the closure sleeve (26) symmetrically about the axis of the tubing (16). The resulting decoupling guarantees that the sleeve (26) is self-centering, which improves the life-span of the device (18) significantly.

Title: Redox flow battery and method of operating it
Inventor: ZOCCHI ANDREA
IPC: H01M50/77
Filed: 2000-03-31
Abstract: By realizing or installing check valve liquid vein interrupters in each compartment of the battery the phenomenon of slow discharge of the retained volumes of electrolytes during long periods of inactivity of a redox flow battery, with the electrolyte pumps stopped altogether, can be practically eliminated with the effect that the battery is perfectly ready to deliver electric power immediately upon request even after prolonged periods of inactivity. Moreover, the presence of liquid vein interrupters on each compartment in either an outlet or an inlet port substantially preventing by-pass current during a not pumping phase, permits to increase the by pumping the electrolytes through the compartments of a battery stack intermittently, in other words in a pulsed manner, with a certain duty-cycle. Relatively brief pumping phases at relatively high flow rate alternated to phases of not pumping provide for a volumetrically adequate refreshing of the electrolytes present in the battery compartments and contrast the formation of gradients in the bodies of electrolyte.

Title: Cleaning system utilizing an organic cleaning solvent and a pressurized fluid solvent
Inventor: SCHULTE JAMES E
IPC: B08B3/12
Filed: 2000-10-13
Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent.  After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether or tripropylene glycol methyl ether, a mixture thereof, or a similar solvent and the pressurized fluid solvent is preferably densified carbon dioxide.
