Patent CA-2589874-A1 (CA)
Title: Inline bladder-type accumulator for downhole applications
Inventor: UNDERWOOD LANCE D
IPC: E21B1/00
Filed: 2007-05-24
Abstract: An accumulator comprises a housing connected to a hydraulic system, an elastomeric bladder separating a gas compartment from a fluid compartment, and an anti-extrusion device. A method for operating an accumulator comprises connecting the accumulator to a hydraulic system, injecting an inert gas into a gas compartment to a precharge pressure, moving an anti-extrusion device to prevent a bladder from extruding into the hydraulic system, running the accumulator and the hydraulic system downhole, moving the anti-extrusion device to allow fluid communication between the hydraulic system and a fluid compartment, generating pressure fluctuations within the hydraulic system, and expanding or contracting the bladder in response to the pressure fluctuations without moving the anti-extrusion device. A method of improving fluid hammer performance comprises connecting the fluid hammer to an accumulator that produces a greater delivered horsepower from the fluid hammer as compared to a baseline horsepower when operating without the accumulator.

Patent CA-2595938-A1 (CA)
Inventor: FORESTELLI FABIO
IPC: G01M99/00
Filed: 2007-07-31
Abstract: La présente invention concerne une façon de mettre à l'essai des bouteilles ou des conteneurs à parois flexibles, s'appliquant dans les lignes de remplissage de bouteilles en plastique, de contenants en aluminium ou en carton revêtu de polyéthylène, ces divers contenants pouvant contenir n'importe quel type de liquide. Appliquée à la sortie du système de remplissage, l'invention permet de vérifier de manière simultanée le bon niveau de remplissage, la présence de fuites possibles dans le système d'étanchéité du contenant et les défauts de fabrication potentiels dans le contenant. L'essai est réalisé grâce à la combinaison de deux mesures : celle du niveau de remplissage et celle de la tension des parois du contenant. Les résultats obtenus de la mesure du niveau de remplissage et de la tension des parois, interpolés de façon appropriée, procurent les indicateurs nécessaires pour établir si le produit analysé doit être considéré comme conforme ou retiré pour cause de défectuosité.

Patent CA-2646694-A1 (CA)
Inventor: THERIAULT MICHELE
IPC: E04C3/02
Filed: 2008-11-27
Abstract: Les éléments structuraux sollicités en flexion sont soumis à des moments et des efforts tranchants importants. Dans la présente invention, le procédé de renforcement structural modifie le parcours des efforts de sorte à créer des forces et des moments qui s'opposent aux forces extérieurs et atténuent leur amplitude. De multiples supports intermédiaires, reliés par des câbles rigides, réagissent aux moindres déplacements du système structural et produisent, à la manière des efforts internes, des réactions inverses s'opposant aux charges. Ces réactions distribuées de façon ponctuelles sont amplifiées par un bras de levier plus important que celui du système flexionnel de sorte à réduire de façon significative la contribution à la reprise des charges de l'élément à  renforcer. Il en résulte un diagramme de moments fléchissant fortement atténué par de multiples moments inverses stabilisateurs ainsi que des poussés verticales s'opposant aux charges en présence. Globalement, les éléments ainsi renforcés présentent une résistance et une rigidité fortement accrue permettant d'augmenter le niveau de chargement ou encore de réduire considérablement l'apport en matériaux dans la confection de l'élément flexionnel.

Title: Fuel-fired, power vented high efficiency water heater apparatus
Inventor: BOROS JOZEF
IPC: F24H9/20
Filed: 2009-01-30
Abstract: A fuel-fired water heater has a draft inducer fan assembly with a housing having an inlet for receiving hot combustion gases discharged from the water heater, and an outlet for discharging the combustion gases. A normally closed damper member within the housing is openable by fluid pressure force created by operation of a draft inducer fan portion of the assembly. With the damper in its open position the fan exhausts the received combustion gases through a housing outlet. When the damper closes it prevents convective outflow through the housing outlet of flue-heated air. In alternate embodiments of the assembly the fan is operative to also draw in dilution air that cools the fan motor and the discharged combustion gases, with the assembly having an internal configuration preventing convective outflow of flue-heated air through the housing dilution air inlet during standby periods of the water heater.
