Patent CA-2505449-A1 (CA)
Inventor: KRESNYAK STEVE
IPC: E21B43/24
Filed: 2005-04-27
Abstract: Methods for thermal recovery of natural gas and bitumen from a formation containing the latter. The methods incorporate a series of existing, but previously uncombined technologies. A modified flue gas from the steam generators conventionally used in a SAGD recovery operation is injected into the formation to enhance recovery with the produced fluids, natural gas, bitumen, inter alia are further processed. The injection of the flue gas conveniently is disposed of and further acts to repressurize the formation which otherwise becomes depressurized when depleted of natural gas. Accordingly, environmental and economic advantages are realized with the methodology.

Abstract: L'invention concerne des procédés et des appareils d'enregistrement auprès d'un agent mère. Le dispositif de réseau envoie une demande d'enregistrement qui comprend un champ d'adresse mère comprenant une adresse IP vers un agent mère associé à ladite adresse IP. La demande d'enregistrement indique un ou plusieurs points d'accès du dispositif de réseau par lesquels les paquets de données ou demandes de serveur adressé(e)s à l'adresse IP sont reçu(e)s. Ces points d'accès peuvent être spécifiés dans une annexe jointe à la demande d'enregistrement. En outre, la demande d'enregistrement peut indiquer une priorité à attribuer à l'enregistrement. L'agent mère met à jour sa table d'associations au moyen de l'adresse IP et de l'adresse transitoire (CoA), ainsi que d'autres informations spécifiées dans la demande d'enregistrement, telles que des informations relatives aux points d'accès et/ou à la priorité. L'agent mère envoie alors une réponse d'enregistrement au dispositif de réseau. Lorsque la demande d'enregistrement n'est pas envoyée directement par le dispositif de réseau (par ex. par l'intermédiaire d'une adresse transitoire de colocation), l'agent relais met à jour sa table de visiteurs à réception de la réponse d'enregistrement au moyen de l'adresse de l'agent mère et de l'adresse IP, ainsi que des informations relatives aux points d'accès et/ou à la priorité. La réponse d'enregistrement est alors envoyée au dispositif de réseau. Il est ainsi possible de procéder à des enregistrements multiples pour un dispositif ou un utilisateur unique, en fonction d'un ou de plusieurs port(s) spécifié(s), ce qui permet d'établir l'ordre de priorité de plusieurs applications et/ou dispositifs.

Title: Force applying apparatus and method
Inventor: RINCOE RICHARD G
IPC: B66F/
Filed: 2004-06-24
Abstract: A force applying apparatus includes a housing that supports a drive motor. A  first extendable member is telescopically received in the housing and moves between a retracted position within the housing and an extended position axially of the housing. A second extendable member is telescopically received in the first extendable member and moves between a contracted position within the first extendable member and an expanded position axially of the first extendable member. The motor drives a ring gear that advances the first extendable member, and a ball nut is mounted in the end of the first extendable member to advance the second extendable member. A spline helps retain the first and second extendable members against rotation but a detent assembly selectively releases the first extendable member for rotation. The apparatus may be used to lift and level a recreational vehicle. A method implemented by this structure is also claimed.
