Abstract: Selon les concrétisations des techniques de cette application, un dispositif de communication de données sans fil ou un autre noeud de communication de données envoie périodiquement des messages de sollicitation à une passerelle sans fil, telle qu'un PDSN, quand il n'y a pas de circulation de données entre le dispositif de communication de données sans fil et un réseau de communication de données sans fil. Chaque message de sollicitation remet à l'état initial la minuterie d'inactivité d'IP simple sur la passerelle sans fil. Lorsque des dispositifs multiples de communication de données sans fil envoient des messages de sollicitation, l'intervalle entre les nouvelles transmissions de messages de sollicitation est randomisé afin de réduire la probabilité de collision avec les sollicitations venant d'autres dispositifs sur la même liaison sans fil. La minuterie de sollicitation, par exemple, peut être basée sur le réglage de la minuterie d'inactivité d'IP simple sur le réseau sans fil, et le nombre de dispositifs de communication de données sans fil que sert le réseau de communication de données sans fil. L'expiration de la minuterie de sollicitation au niveau du dispositif de communication de données sans fil ou d'un autre noeud de communication de données fait envoyer le message de sollicitation suivant depuis ou pour le compte du dispositif de communication de données sans fil.

Abstract: A method and system are provided for creating a mercury halide standard, and for using that standard to test a mercury analyzer system. Gaseous elemental mercury of a known concentration from a gas cylinder and a halogen donor are fed to a reaction chamber where they react to form mercury halide. The mercury halide is fed to a mercury analyzer system where it is converted to reform gaseous elemental mercury which is then measured by a mercury analyzer. By comparing either the amount of elemental mercury supplied to the reaction chamber or the amount of mercury halide formed in the reaction chamber with the amount of elemental mercury converted from the mercury halide, the ability of the mercury analyzer system to convert mercury halide to gaseous elemental mercury can be evaluated.

Title: Simultaneous development of underground caverns and deposition of materials
Inventor: SINGLETON DAVID BRIAN
IPC: E21B43/28
Filed: 2004-10-14
Granted: 2009-03-31
Abstract: A method is provided for simultaneously developing caverns while depositing wastes or other materials in them. A well is first drilled into a salt formation and the development of a salt cavern by means of solution mining is initiated. When the development of the cavern has been carried out to an extent sufficient to accommodate the injection of a prescribed amount of wastes or other materials, injection of the wastes or other materials through the well is started while continuing to develop the cavern by solution mining.  The injection of the wastes or other materials may be carried out continuously or intermittently. The proportion and rates of wastes or other materials and mining water injected into the well are monitored and regulated so that cavern development continues at a rate that allows the cavern to reach an intended prescribed size while the wastes or other materials are injected and deposited into the cavern.

Title: Multi-fuel storage system and method of storing fuel in a multi-fuel storage system
Inventor: GRAM ANKER
IPC: F17C5/04
Filed: 2006-03-22
Granted: 2008-01-08
Abstract: Advantages such as reduced emissions of NOx can be achieved if engines are fuelled with mixtures of gaseous fuels such as hydrogen and natural gas. It is also desirable to store the gaseous fuels separately so that the fuel mixture ratio can be changed responsive to engine operating conditions. However, compared to liquid fuels, a problem with storing gaseous fuels is that they generally require larger storage volumes to hold an equivalent amount of fuel on an energy basis. There are also obstacles to storing some gaseous fuels such as hydrogen in liquefied form because of the energy required to liquefy them and the extremely low temperatures needed to store such gaseous fuels in liquefied form. The invention relates to an apparatus for increasing the storage density of gaseous fuels such as hydrogen by storing them in gaseous form at nigh pressures and at sub-ambient temperatures. An apparatus is provided for separately storing a first gaseous fuel and a second gaseous fuel. A first vessel defines a first thermally insulated space for holding the first gaseous fuel in a liquefied form. A second thermally insulated space that can hold the second fuel is disposed within the first vessel. The second thermally insulated space is separated from the first thermally insulated space by a thermally conductive fluid barrier. The second gaseous fuel liquefies at a lower temperature than the first gaseous fuel, whereby the second gaseous fuel can be stored within the second thermally insulated space in a gaseous form at a sub-ambient temperature.

Inventor: LIN MINJIE
IPC: H04H60/04
Filed: 2004-09-30
Granted: 2014-02-11
Abstract: Route changes are processed and filtered to notify a client of those routing updates of interest to a client. In one configuration, a set of network addresses are received from a client indicating route updates of interest to the client and a set of types of routing changes that are of interest. One or more data structures are accordingly populated with this information. In response to receiving a route update, one or more lookup operations are performed on the data structure to identify whether this particular route is of interest to a particular client and/or whether any route dependent on the particular route are of interest to a client. The client is notified of the changes of interest. In one embodiment, the type of change to a route is also matched against a set of types of routing changes that are of interest, and a client is only notified if the change to a route of interest also matches a type of routing change of interest.

Abstract: Methods and apparatus for shaping pipes, tubes, liners, or casing at downhole locations in wells. Use is made of rollers bearing radially outwards against the inside wall of the pipe (etc.), the rollers being rolled around the pipe to cause outward plastic deformation which expands and shapes the pipe to a desired profile. Where one pipe is inside another, the two pipes can be joined without separate components (except optional seals). Landing nipples and liner hangers can be formed in situ. Valves can be deployed to a selected downhole location and there sealed to the casing or liner without separate packers. Casing can be deployed downhole in reduced-diameter lengths and then expanded to case a well without requiring larger diameter bores and casing further uphole. The invention enables simplified downhole working, and enables a well to be drilled and produced with the minimum downhole bore throughout its depth, obviating the need for large bores. When expanding lengths of casing, the casing does not need to be anchored or made pressure-tight. The profiling/expansion tools of the invention can be deployed downhole on coiled tubing, and operated without high tensile loads on the coiled tubing.
