Patent CA-2221594-A1 (CA)
Inventor: GREINER LEONARD
IPC: C10G9/04
Filed: 1995-06-02
Abstract: Cette invention concerne un appareil qui permet de réduire les émissions d'oxydes d'azote grâce à un mélange d'hydrogène préparé à partir de tout ou partie du carburant du moteur à l'intérieur d'un simple brûleur. Cet appareil comporte un brûleur isolé (10) ayant une chambre de combustion interne (17, 40) qui peut recevoir tout ou partie du carburant gazeux ou du carburant liquide à mélanger à l'air avant l'allumage ultérieur par une bougie (27). Cette chambre se trouve à l'intérieur d'un ensemble de préchauffage de l'alimentation. On dispose d'une chambre de mélange (17, 40) pourvue d'une série de cloisons (22, 23, 32, 37) contre lesquelles se heurtent l'air injecté et la vapeur de carburant, ce qui provoque le mélange complet de l'air et du carburant, le mélange résultant étant ensuite allumé et brûlé, puis évacué vers la chambre de combustion du moteur même. L'ensemble de préchauffage (15, 31) élève la température du mélange entrant air/carburant au moyen d'un processus d'échange thermique avec les gaz issus de la postcombustion de la chambre de combustion. Cet appareil permet d'augmenter la capacité de fonctionnement et les performances grâce à la conservation d'énergie obtenue par l'isolation de la totalité du brûleur, par le positionnement de la section de brûlage à l'intérieur de l'ensemble de préchauffage de l'alimentation, et par celui du flux de mélange d'alimentation de manière adjacente à l'isolation externe (12). Il est également possible d'accroître le rendement en hydrogène en faisant réagir le monoxyde de carbone et de l'eau produite par la réaction principale ou ajoutée séparément.

Title: Method and apparatus for determining geologic relationships for intersecting faults
Inventor: ABBOTT WILLIAM E
IPC: G01V1/30
Filed: 1998-01-15
Abstract: A novel fault framework method and apparatus automatically computes therelationships between intersecting fault surfaces. When faults are loaded into the novel fault framework apparatus, all intersecting fault pairs are determined and the fault fault intersection lines are computed and stored. The intersecting fault pairs are presented and available for automatic calculation of the major/minor and above/below fault pair relationships. The geometry of both intersecting fault surfaces are examined on either side of the fault fault intersection line. This, in combination with the relative size of the faults, is analyzed to compute the major/minor and above/below relationships based on geologic assumptions and knowledge of the origin of the fault surface data. When the relationships between intersecting faults are defined, the minor fault is appropriately truncated.
