Abstract: A purge valve for a mounted assembly for a vehicle consisting of a wheel comprising a rim and of a tire, the valve comprising a body associated with the rim and a piston able to move with respect to the body between a closed position and a purge position and the valve being normally closed. The opening of the valve is obtained by the moving of the piston into the space radially external to the rim, the opening being obtained by action of a control force on the piston, exerted from the space radially internal to the rim, and provided by compressed air led from the space radially internal to the rim to the radially interior surface of the piston and the compressed air led from the space radially internal to the rim to the radially interior surface of the piston being at a pressure lower than or equal to that of the mounted assembly.

Abstract: La présente invention concerne un ensemble table pour un dispositif de transfert de patient. Ledit ensemble présente des tables inférieure et supérieure entourées de courroies qui vont dans le sens de rotation contraire lorsque l'ensemble table se déplace entre un patient et une surface de soutien, telle qu'un lit. L'ensemble table inclut des moyens intégrés destinés à rétracter des plaques latérales de la table supérieure, tout en ajustant les angles d'incidence desdites plaques latérales et en séparant verticalement la table supérieure de la table inférieure. Des fentes de guidage dans des plaques d'extrémité fixées à un ensemble coulissant maintiennent des piliers de positionnement fixés aux extrémités des plaques latérales. Les fentes sont inclinées vers le haut en direction d'un axe de l'ensemble table à des angles différents. Une manivelle déplace les plateaux latéraux au moyen d'un disque de rotation fixé à un cadre central de la table supérieure, et au moyen de bras de liaison. Ces bras présentent une extrémité fixée de manière pivotante à une région périphérique du disque et une autre extrémité fixée de manière pivotante à l'un des piliers de positionnement. Dans un mode de réalisation alternatif, les plaques latérales de la table supérieure s'étendent de manière différentielle aux extrémités, et le contrôle de valve pour le tube pneumatique est intégré à la rétraction des plaques latérales. Durant le transfert du patient, seule la plaque latérale de transfert est soulevée, ce qui évite que le linge ne se coince dans l'espace formé entre les courroies supérieure et inférieure. L'ensemble coulissant soutenant l'ensemble table inclut une plaque fixe, une plaque intermédiaire, et une plaque animée qui s'étendent au moyen d'engrenages à crémaillère. Chaque plaque est symétrique, et les pignons sont situés symétriquement sur des côtés opposés de la plaque fixe ou intermédiaire, pour permettre l'hyper-extension vers la gauche ou vers la droite. Deux roues d'axe qui vont dans le sens de rotation contraire depuis une position droite jusqu'à une position tournante, puis une position latérale, permettent d'améliorer la commande du dispositif. Lesdites roues sont orthogonales par rapport à l'axe longitudinal du dispositif.

Abstract: Statistics have shown that more than 53% of Canadians carry at least one rewards card (Aeroplan, Petro Points, HBC, etc.), and most carry between 3 to 5 rewards cards. However, less than 30% of Canadians have actually ever used their rewards for a major purchase or trip. A valid reason for this may be that there are too many rewards cards in the average Canadian household to keep track of and to efficiently use. This invention is targeted to the 53% of Canadians who have rewards cards and allows them to consolidate the various cards (up to rewards 8 cards) into one card, created with the use of unique rewards barcode identification and printing method.

Inventor: BAMMEL BRIAN D
IPC: C09D101/00
Filed: 2009-05-19
Abstract: Disclosed is a method for providing an anti -corrosion protec-tive coating to a metal substrate that uses a coating composition comprising a resin and a polyfunctional bridging molecule to both bind to the resin and to chelate the bound polymeric resin directly to the metal substrate. One category of polyfunctional bridging molecules preferably includes at least one amine function to bind to a resin and at least one carboxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phosphonate function to chelate to a met-al substrate. It is theorized that the amine function can bind to certain pendent chains in coating resins through a Michael addition reaction while the car-boxylate, thiol, silane, phenolate, acetoacetonate, imine, phosphate, or phos-phonate functions chelate to the metal substrate. These polyfunctional bridg-ing molecules provide an organic binding of the resin to the metal substrates.

Title: Downhole hydraulic jetting assembly, and method for stimulating a production wellbore
Inventor: RANDALL BRUCE L
IPC: E21B7/18
Filed: 2011-02-25
Abstract: A method for forming multiple lateral boreholes from an existing wellbore is provided.  The wellbore has been completed with a string of production casing. The wellbore may have a slimhole region having an inner diameter that is less than the inner diameter of the production casing. The method generally comprises providing a downhole apparatus having a whipstock.  The whipstock may be a single piece tool that rotates into position below the slimhole region, or it may be a two piece tool comprising a top whipstock member and a separate bottom whipstock member. The whipstock has a curved face. The method also includes running the apparatus down into the parent wellbore. A force is applied to the apparatus to cause the whipstock to rotate within the wellbore into an operating position. In this position, the curved face of the whipstock forms a bend-radius that allows the jetting hose to bend across the entire inner diameter of the production casing. A jetting hose is run into the wellbore.  Upon contact with the curved face of the whipstock, the jetting hose is re-directed through a window in the production casing. Hydraulic fluid is injected under pressure through the hose to provide hydraulic jetting.  The hose is directed through the window and into the formation to create a lateral borehole extending many feet outwardly into a subsurface formation. A downhole jetting assembly for forming multiple lateral boreholes from a parent wellbore is also provided herein. The assembly utilizes substantially the entire inner diameter of the casing as the bend radius for a hydraulic jetting hose, thus providing for the maximum hydraulic horsepower at the jetting nozzle.
