Abstract: Magnetic composites exhibit distinct flux properties due to gradient interfaces. The composites can be used to improve fuel cells and batteries and effect transport and separation of different chemical species. Devices utilizing the composites include a separator, an electrode (804) for channeling flux of magnetic species, an electrode (804) for effecting electrolysis of magnetic species, a system for channeling electrolyte species, a system for separating particles with different magnetic susceptibilities, improved fuel cells, batteries, and oxygen concentrators. Some composites can be used to make a separator for distinguishing between two species of materials and a flux switch to regulate the flow of a chemical species. Some composites can control chemical species transport and distribution. Other composites enable ambient pressure fuel cells having enhanced performance and reduced weight. Some other composites enable rechargeable batteries that have longer secondary cycle life and improved output power. Still other composites, disposed on the surface of electrodes, prevent passivation of those electrodes and enable direct reformation of liqui fuels. Methods involving these composites provide distinct ways for these composites to be utilized.

Title: Method and arrangement for producing fuel gas
Inventor: LIEBISCH GUNTER
IPC: C10J3/24
Filed: 1996-06-26
Granted: 2002-04-23
Abstract: The invention concerns a process and apparatus for gasifying carbon-containi ng products, in particular waste and residues conditioned or processed in a suitable way. Gasification takes place in a mixed flow composed of a counter  flow, direct flow and transverse flow. A portion of the gasifying agent is introduced through an inclined grate in the form of a step grate and thrust grating and ash is removed at the bottom end of the grate. Fuel gas is drawn  off above the upper level of the grate on the side opposite the lateral feed  of the gasifying agent. The gasification apparatus is enclosed in a double- layer insulating/cooling system in which air is used as the insulator and coolant. The gasification process is regulated by the temperature profile of  the gasification apparatus, the position of the principal gasification zone is adjusted by ash discharge, the gasification temperature is regulated by the flow of gasifying agent and the output is regulated by the width of the gasification zone. The fuel gas produced is used preferably for generating electricity in a work machine. Exhaust gases are purified preferably with th e aid of an active coke filter.

Granted: 2007-09-11
Abstract: A process for enhanced oil recovery from an extraction operation comprises the steps of selection of an appropriate hydrocarbon bearing stratum; providing at least one production well and one injection well; and injecting into the target stratum a slurry formed from sand, viscous liquids or oily sludge, which is delivered at or near formation fracture pressures. Monitoring of bottom hole pressure is carried out, to permit delivery of the slurried wastes in a series of injection episodes, in which the length of the episodes and interinjection periods is determined by maintaining the bottom hole pressure within a preselected range. The position and spread of the slurried wastes within the target stratum may be monitored through the use of additional monitoring steps.

Title: Pressure-balanced rod piston control system for a subsurface safety val ve
Inventor: ADAMS JEFFREY K
IPC: E21B34/00
Filed: 1999-10-15
Granted: 2004-12-14
Abstract: A control system for a subsurface safety valve (SSV) comprising of a control line from the surface in fluid communication with the top side of an actuating piston which moves a flow tube downwardly to open the SSV. A balance line runs from the surface to the bottom side of the same actuating piston to put the actuating piston in pressure balance. A buildup of pressure in the control line overcomes a return spring to open the valve, while removal of pressure from the control line allows the return spring to close the valve.      Seals and leakpaths are provided through the actuating piston so that, depending on the hydrostatic pressure in the control line and the size of the return spring, the various failure modes of the actuating piston seals and control line or balance line will preferentially result in a fail-closed situation in the SSV.
