Abstract: A fuel-fired air heating furnace is provided with NOx reduction apparatus associated with a plurality of combustor tubes forming a portion of the furnace heat exchanger section. Inshot-type fuel burners are spaced apart from and face the open inlet ends of horizontal combustion sections of the combustor tubes. The NOx reduction apparatus includes a plurality of NOx reduction members formed from a metal rod material, and a mounting plate having a row of spaced apart pairs of mounting holes therein. Each NOx reduction member has an elongated, generally U-shaped configuration, with a closed inner end, an open outer end, and a spaced pair of corrugated leg portions extending between such inner and outer ends. The NOx reduction members are installed in a parallel relationship on the mounting plate, with their closed ends facing in the same direction, by resiliently deflecting the leg portions of each member toward each other, inserting the outer leg ends in one of the mounting plate hole pairs, and then releasing the legs. With the NOx reduction members secured to the mounting plate in this manner, they are simultaneously inserted closed ends first into their associated combustor tubes, and the mounting plate suitably supported adjacent the combustor tube inlets. The burners are then positioned to inject flames into the combustor tubes with the NOx reduction members positioned therein to operatively intercept the incoming burner flames.

Title: System and methods for performing endovascular procedures
Inventor: GIFFORD HANSEN S III
IPC: A61F2/958
Filed: 1996-03-11
Abstract: This invention is a system for inducing cardio-plegia arrest and performing an endovascular procedure within the heart or blood vessels of a patient. An endo-aortic partitioning catheter (10) has an inflatable balloon (11) which occludes the ascending aorta (12) when inflated. Cardio-plegia fluid may be infused through a lumen of the endo-aortic partitioning catheter (39) to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass. One or more endovascular devices (500) are introduced through an internal lumen (40) of the endo-aortic partitioning catheter (30) to perform a diagnostic or therapeutic endovascular procedure within the heart or blood vessels of the patient. Surgical procedures such as coronary artery bypass surgery or heart valve replacement may be performed in conjunction with the endovascular procedure while the heart is stopped. Embodiments of the system are described for performing, e.g., fiberoptic angioscopy of structures within the heart and its blood vessels, and valvuloplasty for correction of valvular stenosis.

Abstract: L'invention vise un procédé de préparation d'un nanocomposite à base de magnésium et d'un autre élément ou composé connu pour absorber l'hydrogène et être peu miscible au broyage avec le magnésium ou son hydrure, te l le vanadium ou le nobium. Selon ce procédé, on soumet le magnésium ou un composé à base de magnésium connu pour absorber l'hydrogène à une hydrogénation en vue d'obtenir l'hydrure correspondant sous la forme d'une poudr e. On mélange alors la poudre d'hydrure ainsi obtenue avec l'autre élément ou composé ou un hydrure de cet autre élément ou composé et on soumet le mélange ainsi obtenu à un broyage mécanique intense jusqu'à obtention du nanocomposite correspondant sous la forme d'un hydrure. Enfin, on soumet le nanocomposite ains i obtenu à une désorption d'hydrogène. L'invention vise aussi le nanocomposite à base de Mg ainsi préparé, qui a l'avantage d'être peu coûteux et d'avoir des performances inégalées pour le stockage de l'hydrogène grâce à sa microstructure (c'est-à-dire à la nature des interfaces et à la distribution spatiale de ses composantes) qui est extrêmement fine et donne lieu à un effet de synergie incroyable entre le Mg et l'autre élément ou composé.

Abstract: Les ventilateurs à pression positive motorises sont principalement utilisés pour évacuer fumées, gaz toxiques et chaleur intense lors de combats d'incendies. Ils sont aussi utiles pour éliminer des émanations toxiques de différentes sortes sur des sites en construction, des bâtiments d'élevage, des édifices commerciauxet industriels. En ce qui concerne les ventilateurs à pression positive, nous savons que les appareils utilisés actuellement, fonctionnent de façon stationnaire, sont encombrants et disposent de peu de possibilités d'ajustement lorsque la direction du jet d'air doit être modifié. De plus, ceux comportant un niveau de CFM élevésont trop lourd et de grandes dimensions. La présente invention offre une plus grande liberté d'intervention. Placé dans son support stationnaire, d'appareil présente une variété d'angles et de positions de fonctionnement permettant de diriger le jet d'air dans la directiondésirée De plus l'appareil dans son ensemble est plus petit et plus léger que tout autre appareil de même niveau de puissance. Retiré de son support stationnaire, il se porte à la main, offrant à l'utilisateur plus de légèreté etla possibilité d'intervenir dans une multitude de situations ou il serait difficile et souvent impossible d'agir avec les appareils conventionnels.
