Title: Method and apparatus for coordinating a change in service provider between a client and a server
Inventor: NGUYEN HAN Q
IPC: H04L29/08
Filed: 2001-03-20
Abstract: A method of configuring a network access device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a subscriber of services of a second service provider provided by a second service network, wherein the network access device is connected to an access network connected to a plurality of service networks. The method comprises the steps of: sending a request from the network access device to the access network requesting a change to a second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the subscriber of services of the second service provider is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. In one preferred embodiment of the invention, the subscriber is authenticated by a service activation system coupled to the access network prior to initiating the configuration protocol. Accordingly, the request to the access network includes an authentication request for the subscriber. The response received from the access network therefore includes an authentication status for the subscriber from the second service provider. If the subscriber is authenticated, the client initiates the network address change request.

Abstract: L'invention concerne un système et un procédé améliorés pour l'hydrogénation catalytique de monoxyde de carbone, visant à former un mélange d'hydrocarbures par le biais d'une pluralité de réacteurs en série. Un gaz de synthèse pénétrant dans le système sous pression est partiellement converti dans au moins un réacteur de phase initiale, et les effluents sont ensuite injectés dans un réacteur de phase finale. Dans le ou les réacteurs de phase initiale, on extrait continuellement ou périodiquement une partie du catalyseur avec un certain nombre d'hydrocarbures, que l'on soumet à un traitement aux fins de renouvellement, ou de renouvellement et d'amélioration, et que l'on réintroduit ensuite. Le traitement comprend les étapes suivantes: réduction du contexte d'hydrocarbures du mélange extrait, échauffement à une température dépassant au moins celle de l'un des métaux du catalyseur, pour former un produit fondu, élimination de toute scorie formée sur le produit fondu, refroidissement du produit fondu et réduction de la taille des particules du produit solide résultant, sous la forme d'une fine poudre de catalyseur renouvelé. Ce catalyseur peut être traité plus avant (amélioration plus poussée des propriétés) par oxydation en suspension à basse température ou par passivation avant réinjection dans le ou les réacteurs de phase initiale. Le réacteur de phase finale, qui comporte un catalyseur identique ou différent de celui du ou des réacteurs de phase initiale, reçoit de la part de ce ou ces réacteurs une charge à teneur sensiblement réduite en impuretés, ce qui permet d'améliorer l'efficacité et la longévité du catalyseur. Le système peut également faire appel à au moins un réacteur de phase intermédiaire, dans une configuration faisant que toutes les phases sont reliées opérationnelles en série et que tous les réacteurs d'une phase donnée sont reliés en parallèle.

Abstract: La présente invention porte sur une matrice flexible de fibres non tissées pyrolysées, appropriée pour être utilisée comme substrat d'électrode de pile à combustible. Le produit est caractérisé par une microporosité régulée et est au moins partiellement hydrophobe. Le produit est fabriqué selon un processus de fabrication continu, à haute vitesse et rendement élevé, ce qui permet de varier largement les paramètres tels que le poids de base (50-150 gm/m?2¿), l'épaisseur (140-400 m?2¿ à 5 Kpa), la densité (0,300-0,480 gm/cm?3¿) et la résistivité (200-1000 mOhm-cm dans le plan et 15-65 mOhm-cm sur le plan). Cette matrice, à la différence des substrats d'électrodes habituels, est flexible et peut être conçue comme des marchandises en rouleau. Un test comparatif des applications de pile à combustible a démontré que ce substrat d'électrode est réalisé par comparaison avec des substrats d'électrode habituellement disponibles. La pile à combustible pourvue du substrat d'électrode de cette invention a une courbe de polarisation qui est virtuellement identique à celle produite par la pile à combustible pourvue d'un substrat d'électrode traditionnel.
