Granted: 2004-04-27
Abstract: The present invention relates to a method and a device for measuring volume flow rates of liquid phase components and gas and determinating their volume concentrations in a multiphase mixture along a pipeline. Measurements are executed with an ultrasonic system which includes a set of local acoustic transducers arranged in the interior of the pipeline. Each pair of an emitter and a receiver of the transducer forms a sampling volume of a medium being under control. Volume concentrations of mixture components are determined by timing of pas- sage of acoustic pulses through the sampling volume of the medium. Volume flow rates of the mixture components are calculated by measur- ing phase velocities and volume concentrations in two pipeline divisions with different cross-section areas located in series at a distance one from the other in flow direction.

IPC: H01M50/497
Filed: 2002-09-13
Granted: 2010-01-26
Abstract: A process for production of a composite porous film wherein a porous support, of which both sides have been coated with a solution (dope) of an organic polymer compound in a water-soluble organic solvent to form a coated film, is passed through an air gap step and conveyed into a coagulating bath comprising water or a mixture of water with the same solvent as the organic solvent, and is then immersed in the coagulating bath so that the coated film on both surfaces of the porous support directly contact the coagulating bath for coagulation, and is then washed and dried. This production process is suitable for production of non- aqueous secondary battery separators, and yields non- aqueous secondary battery separators with good handling properties and at low cost, whereby the ion permeability, adhesion with electrodes and electrolyte solution retention can be strictly controlled.

Granted: 2006-12-12
Abstract: A method and system for downhole treatment and pumping of well fluids enhances the pumping of viscous fluids to the surface. The first step is to separate the oil and water from the well fluid and then channel the oil to a chamber that encloses the motor. The heat from the motor will increase the heat of the crude oil flowing past the motors thereby lowering the viscosity of the crude oil. The water flows separately past the motor in another passageway, and remixes with the oil. After the oil and water recombine, the treated well fluid has a lower viscosity, and the fluid is then pumped to the surface more efficiently than without treating the oil.

Abstract: L'invention concerne un système (10) permettant de pomper ou de mélanger un fluide au moyen d'un support magnétique de lévitation et de rotation, ainsi que divers composants à utiliser dans un système de pompage ou de mixage. Le support magnétique (14) est placé dans un récipient renfermant un fluide (16), de manière à être positionné à proximité étroite d'un élément superconducteur (16). Une source distincte de refroidissement (24), thermiquement reliée à l'élément superconducteur, fournit le refroidissement nécessaire pour induire une lévitation dans le support magnétique.

Abstract: A reactor system comprising two or more subterranean reactors for high pressure treatment of materials. The reactors each comprise an inlet tube, a reaction region and an outlet tube and are deep enough for material in the inlet and outlet tubes to produce significant hydrostatic pressure. The reactors are adapted to exchange heat which may occur through a shared heat transferring wall or a heat exchanger including circulating liquid. The invention also extends to a method of simultaneously running two processes in the reactor system. The preferred processes are hydrothermal dewatering of coal, especially brown coal, and coal liquefaction wherein exothermic heat product of one process contributes to the heating requirements of the other process. The invention also extends to a method of hydrothermal dewatering of coal when conducted in a subterranean reactor in conditions of decreasing pressure.

Title: High speed serial data transport between communications hardware modules
Inventor: KAKU VICKY B
IPC: H04N21/236
Filed: 2002-09-11
Granted: 2009-09-08
Abstract: Transcoder multiplexers that transport digital packets, such as MPEG2 packets, between boards in a chassis using a serial differential protocol are disclosed. The disclosed multiplexers achieve data transfer rates at least twice as fast as conventional systems. Digital data packets are thereby efficiently communicated to target processing engines on other boards across the backplane. Prior art requirements for custom backplane designs, together with discrete hardware for sending data in parallel form between boards, are obviated. Instead, a backplane architecture designed specifically for IP data traffic from any slot to any slot is utilized. Also, an improved protocol is applied for transmitting data serially between boards to provide an inexpensive, upgradeable and flexible hardware solution. Preferred embodiments use LVDS transmitter/receiver pairs with high link speeds.

Abstract: The present invention generally relates to a method and an apparatus for stimulating the production of an existing well. In one aspect, a method of treating a well is provided. The method includes inserting a selective treatment assembly and a plug assembly into a partially lined wellbore until the selective treatment assembly is positioned proximate an area of interest. Thereafter, the selective treatment assembly is activated to isolate and treat the area of interest. Next, the selective treatment assembly is deactivated and urged toward the surface of the well until the plug assembly is seated in a polished bore receptacle disposed in a string of casing. At this point, the treated portion of the wellbore is separated from the untreated portion. Thereafter, the pressure in the untreated portion of the wellbore is equalized with the surface of the well and then the selective treatment assembly is removed from the wellbore while the plug assembly remains in the polished bore receptacle. Next, a string of production tubing is disposed in the wellbore and attached to the polished bore receptacle. The plug assembly is then removed from the polished bore receptacle and the well is produced. In another aspect an apparatus for treating a portion of a wellbore is provided.
