Patent CA-2562254-C (CA)
Inventor: MIDYA PALLAB
IPC: H03M1/34
Filed: 2005-03-10
Granted: 2009-05-26
Abstract: L'invention concerne un système et un procédé de conversion analogique-numérique faisant appel à la modulation de largeur d'impulsion (MLI) numérique. Le procédé et le système selon l'invention convertissent un signal d'entrée analogique en un signal numérique sous forme modulée par impulsions codées (MIC). Cette invention utilise un circuit de retour pour effectuer une MLI du signal d'entrée analogique. Le signal MLI est ensuite décimé pour obtenir le signal numérique sous forme MIC. Le système selon l'invention nécessite une fréquence de fonctionnement inférieure et dissipe moins de puissance comparativement aux systèmes selon l'art antérieur fournissant la même fréquence d'échantillonnage et la même résolution. Le fonctionnement à une fréquence inférieure est possible par obtention de deux échantillons de chaque impulsion du signal MLI, le premier échantillon étant obtenu à partir du facteur de marche droit et le second échantillon à partir du facteur de marche gauche. L'invention se caractérise en outre par une complexité de mise en oeuvre réduite et un rapport signal-bruit accru comparativement à l'art antérieur.

Title: Improved tire installation and removal tool
Inventor: VAN TRAN LOI
IPC: B60C25/02
Filed: 2006-10-11
Granted: 2010-04-27
Abstract: A tool is provided for assistance in removing and installing tires on wheel rims. The tool can be provided with a handle having a tool head disposed at each end. Each tool head is designed to fit between a tire bead and an associated wheel rim so that when the handle is levered, a force is applied to the bead and rim that moves the bead over the rim. Each tool head has a substantially flat portion which can be easily fit between opposing tire and wheel rim surfaces. One tool head has a slightly hooked distal tip to enable axial engagement with a flange of the wheel rim, and thus can be used either for installing a tire on a rim or for removing a tire from the rim. Another tool head has a protrusion disposed near the tool midpoint to engage a flange of the wheel rim. The protrusion can be a roller member having a pin axis perpendicular to an axis of the tool handle. This roller can be fabricated from a soft polymer or rubber material so that the tool will not damage soft-metal wheel rims such as aluminum. The handle can have a pronounced curvature that allows a portion of the handle body to be received within the cavity formed by the wheel rim. This curvature allows for a greater range of motion of the handle, thus providing the user improved leverage as compared to prior tools. The tool heads may be permanently attached to the handle, or they may be removable to allow the user to customize the tool to the desired application.

Granted: 2012-08-21
Abstract: L'invention concerne un procédé de fabrication de catalyseurs constitués d'un alliage à base de métal noble présentant un degré élevé d'alliage et une taille de cristallite réduite. Ce procédé se base sur l'utilisation de solvants à base de polyol comme milieu de réaction et comprend un processus de réduction en deux étapes en présence d'un matériau de support. Dans la première étape, on active le premier métal (M1 = métal de transition ; par exemple, Co, Cr, Ru) en augmentant la température de réaction jusqu'à une fourchette allant de 80 à 160 °C. Dans la seconde étape, on ajoute le second métal (M2 = métal noble ; par exemple, Pt, Pd, Au et des mélanges de ces derniers) et la suspension boueuse à un point d'ébullition du solvant à base de polyol situé dans une fourchette allant de 160 à 300 °C. Grâce à ce procédé en deux étapes, on obtient une réduction uniforme qui permet de fabriquer des catalyseurs à base de métal noble présentant un degré élevé d'alliage et une taille de cristallite réduite inférieure à 3 nm. En raison du degré élevé d'alliage, les constantes de réseau cristallin sont abaissées. Les catalyseurs fabriqués conformément au procédé selon l'invention sont utilisés en tant qu'électrocatalyseurs pour des piles à combustibles à membrane à électrolyte polymérique (PEMFC), des piles à combustibles directes au méthanol (DMFC) ou en tant que catalyseurs en phase gazeuse pour l'oxydation de CO ou la purification des gaz d'échappement.
