Title: Method and apparatus for vaporizing fuel
Inventor: NEWHOUSE LESLIE A
IPC: F02M31/18
Filed: 2000-08-22
Granted: 2005-12-20
Abstract: A method and apparatus is provided for the vaporization of liquid hydrocarbo n fuel in a closed system prior to its entry into an internal combustion engine's combustion chambers in amounts proportional to the acceleration lev el of the engine. The apparatus is a fuel vaporizer (10) interposed between an engine's fuel injection system and combustion chambers and forms a canister housing. Liquid fuel enters via an inlet (16) in the housing, is vaporized b y heating it to boiling and is drawn out of the canister via an outlet (26) under a partial vacuum to the combustion chambers of the engine. The system is closed except for a vacuum connection with the engine's combustion chambers. Heating means (12) are provided to heat the fuel to boiling without heating it to its flash point, thus avoiding its pre-ignition.

Patent CA-2404927-C (CA)
Title: Tendeur
Inventor: SERKH ALEXANDER
IPC: F16H7/08
Filed: 2001-04-12
Granted: 2006-05-30
Abstract: cette invention concerne un tendeur de courroie mécanique complet qui produit un effet d'amortissement, lequel est fonction de la charge résultant de forces de frottement produites par l'action coulissante de coins opposés. Un premier coin ou piston conique est logé dans un boîtier. Ce piston conique coopère avec un second coin. Une surface du coin glisse sur la surface intérieure du boîtier. Le coin est extensible dans une direction perpendiculaire à la surface intérieure du boîtier. Un ressort force le coin à s'engager dans le piston conique. Lorsque la poulie est soumise à une charge, par impulsion par exemple, le piston pénètre dans le coin. Ce mouvement amène à son tour le piston à se dilater contre la surface intérieure du boîtier. L'expansion du coin dans le boîtier s'accompagne d'une augmentation de la force de frottement entre le coin et le boîtier avec pour conséquence un amortissement des déplacements du piston conique et ipso facto, de la poulie. Plus l'impulsion est importante, et plus grande est l'expansion du coin. Le mouvement de résistance au forces de frottement augmente entre le coin et le boîtier. Lorsque la charge retombe, la force de frottement diminue également, ce qui facilite le rappel du piston.

Abstract: Un système d'alimentation et d'entreposage de gaz naturel, en particulier approprié pour une utilisation dans les véhicules alimentés par le gaz naturel liquide (G N L), inclut un réservoir isolé contenant une alimentation en GNL avec un espace livre au-dessus. Une pompe et un vaporisateur sont en circuit entre le réservoir et le moteur du véhicule. Quand elle est activée, la pompe met sous pression le GNL du réservoir et le dirige vers le vaporisateur où le GNL gazeux est produit. Le GNL gazeux sous pression est acheminé vers le moteur où il est consommé sous forme de carburant. Un circuit communique avec l'espace libre du réservoir et inclut un régulateur, une soupape de contrôle et un dispositif de contrôle de flux. La soupape de contrôle s'ouvre quand le moteur du véhicule fonctionne et le régulateur s'ouvre quand la pression dans le réservoir dépasse un niveau prédéterminé, de telle sorte que la vapeur du GNL provenant de l'espace libre du réservoir pénètre dans l'arrivée d'air du moteur du véhicule où elle est consommée. Le dispositif de contrôle de flux, qui peut être un orifice ou une soupape de contrôle de flux, est paramétré pour éviter que le mélange de vapeur et d'air du GNL créé à l'arrivée d'air ne soit combustible dans le moteur du véhicule.

Abstract: One approach to treating individuals infected with HIV-1 is to administer to such individuals compounds that directly interfere with and intervene in the machinery by which HIV-1 replicates itself within human cells. Although the specific role of HIV-1 viral protein Vif in the viral life cycle is not known, the Vif gene is essential for the pathogenic replication of lentivirusesin vivo. The present invention relates to a method for treating an individual exposed to or infected with HIV-1. Individuals identified as being exposed to or infected by HIV-1 are administered a therapeutically effective amount of one or more compounds that inhibit or prevent replication of said HIV-1 by interfering with the replicative or other essential functions of HIV-1 viral protein Vi, by interactively blocking the multimerization domain of Vif, thereby preventing multimerization of Vif protein, which is important for Vif function in the lentivirus life cycle. In preferred embodiments, the compound or compounds that interactively block the multimerization domain of Vif are Vif antagonists. Pharmaceutical compositions comprising these compounds are also disclosed.
