Patent CA-2377166-C (CA)
Inventor: NEBRIGIC DRAGAN DANILO
IPC: H01M10/48

Granted: 2006-05-30
Abstract: La présente invention concerne un transformateur de courant continu dont la commutation permet la délivrance d'une tension de sortie attendue aux bornes d'une capacité de charge en fonction des besoins d'un dispositif de charge. Plus particulièrement, un élément capacitif et/ou inductif est commuté entre un état de charge et un état de décharge de façon à entretenir la tension de sortie. Dans le cas d'un transformateur de type capacitif uniquement, ou d'une pompe de charge, la comparaison de la tension de sortie à une tension de référence permet de commuter avec succès une capacité volante à la transition entre état de charge et état de décharge. En outre, on effectue une comparaison hystérétique entre la tension de sortie et des seuils définis d'arrêt de la modulation d'impulsions en largeur. Cela offre une meilleure efficacité du transformateur électrique dans le cas où la commutation de l'élément utilise un redresseur et un commutateur synchrones pour charger la capacité de charge dès que la tension de sortie voulue est atteinte. Les transformateurs électriques de l'invention conviennent particulièrement aux applications de circuits électriques. En combinaison avec d'autres éléments d'une batterie, ils permettent la réalisation de batteries plus efficaces se distinguant par leur longévité et la stabilité de leur tension de sortie.

Abstract: Bow and stern sections (1, 2) of a boat are hinged together to enable the bow section (1) to be folded over the stern section (2) which has wheels (6) deployed for towing and storage on land. The folded boat is towed by a towbar (10) bolted to a retracted spine (8) of a chassis (7) on which the stern section (2) is mounted. The spine (8) is extendable telescopically to support the unfolded bow section (1), and the wheels (6) are pivotally-mounted on the chassis (7) to be retracted by over-centre operation, into open-bottom compartments (26) of the stern section (2); an interlock with the spine (8) precludes wheel-retraction while the spine (8) is retracted. Spring-biased doors (36) are freed to close the open-bottoms of the compartments (26) in response to retraction of the wheels (6). The hinging of the bow and stern sections (1, 2) is via a panel (5) which is pivoted to both sections (1, 2) and which closes a gap between bulkheads (3, 4) in the folded boat and provides a seat over them when the bow section (1) is unfolded.

Title: Method and apparatus for combustion of residual carbon in fly ash
Inventor: CRAFTON PAUL M
IPC: F23C10/04
Filed: 2000-11-02
Granted: 2007-10-02
Abstract: A system for combustion and removal of residual carbon within fly ash particles (F) in which the fly ash particles are fed into a particulate bed (40) within a reactor chamber (21). The fly ash particles are subjected to heat and motive air (37) such that as the fly ash particles pass through the particulate bed, they are heated to a sufficient temperature to cause the combustion of the residual carbon within the particles. The fly ash particles thereafter are conveyed in a dilute phase (28) for further combustion through the reactor chamber away from the particulate bed and exhausted to an ash capture (45). The fly ash is then separated from the exhaust air that conveys the ash in its dilute phase with the air being further exhausted and the captured fly ash particles being fed to a feed accumulator (80) for re-injection to the reactor chamber or discharged for further processing.

Title: Apparatus and method for withdrawing and dewatering slag from a gasification system
Inventor: WINTER JOHN D
IPC: F23J1/02
Filed: 2000-08-31
Granted: 2012-11-13
Abstract: The present invention relates to an apparatus and method for withdrawing and dewatering slag from a gasification system. In particular, the present invention relates to a conveying lockhopper and method of using the conveying lockhopper to collect slag and other waste byproducts from the gasifier of a gasification system. The conveying lockhopper is configured to receive slag from a gasifier, simultaneously extract and dewater the slag, and expel the processed slag directly into an awaiting container suitable for carrying the processed slag away. The conveying lockhopper generally comprises a housing with inlet and outlet valves to receive and expel slag, respectively. The housing is inclined at an angle typically between 5 and 60 degrees to the horizontal so that the outlet is at a higher elevation than the inlet. Inside the housing, an auger or similar conveying mechanism conveys the slag from the inlet towards the outlet while simultaneously dewatering the slag. As a result, the processed slag that is discharged at the outlet is fully processed and ready to be transported away.

Abstract: Description des méthodes et d'un appareil de commande de vitesse durant le codage par double passage. Un codeur de premier passage code des tranches alternées de trames d'ancrage sous la forme de tranches I et P respectivement dans le but de générer des statistiques pour le codage des trames I et P pour la même trame d'ancrage. Une estimation de la complexité initiale pour le codage d'une trame en cours est déterminée par le codeur de premier passage en fonction de statistiques du codage de premier passage de la trame en cours et à partir du codage de premier passage d'une trame codée antérieure. Un codeur de deuxième passage estime la complexité de l'encodage pour la trame en cours en fonction de la complexité initiale et des statistiques du codage de deuxième passage de la trame codée antérieure. Le codeur de deuxième passage détermine alors une capacité binaire allouée pour le codage de deuxième passage de la trame en cours en fonction de la complexité de l'encodage.

Abstract: A shoe stud (1, 101) for a sports shoe has a ground-engaging part and a multi-start threaded spigot (5, 105) for engagement in a complementary socket (37, 137) on a receptacle (2, 102) secured in the shoe sole or heel. The stud and receptacle also have a locking device which interengages when the spigot is fully inserted into the socket, to resist unscrewing. In order to ensure that the stud takes up a precise position relative to the receptacle, which may be needed if the stud is not rotationally symmetrical, the stud and receptacle have means (11, 12; 111, 112) to determine the initial position of the stud relative to the receptacle, and means (13, 113) to determine the final position of the stud relative to the receptacle.       Determination of the initial position may be provided by a thread (12, 112) and complementary groove (11, 111) of the screw-thread connection which are of different dimensions from the others.

Abstract: A correction curve is prepared by plotting 1X02 concentrations and 13CO2/12CO2 concentration ratios which are determined on the basis of a calibration curve and 13CO2 and 12CO2 absorbances of gaseous samples having the same 13CO2/12CO2 concentration ratio but known different 12CO2 concentrations. A gaseous teat ample containing 13CO2 and 12CO2 as component gases is introduced into a cell, and spectrometrically measured. A 12CO2 concentration of the gaseous test sample is determined by way of the spectrometric measurement. A concentration ratio correction value is obtained on the basis of the correction curve and the 12CO2 concentration of the gaseous test sample thus determined. A measured 13CO2/12CO2 concentration ratio is divided by the concentration ratio correction value thus obtained for correction of the 13CO2/12CO2 concentration ratio. Thus, the measurement accuracy of the concentration ratios of the component gases can be improved.

Granted: 2009-04-28
Abstract: In gray-scale correction where extension to a dynamic range is performed based on a maximum value and a minimum value of a video luminance signal, sufficient correction effects cannot be obtained in some displayed images. Therefore, a histogram detecting circuit (2), a maximum value detecting circuit (3), and a minimum value detecting circuit (4) respectively detects, for each field, a maximum value (Kmax) and a minimum value (Kmin) in a detection WINDOW set in a screen, and distribution information in a gray-scale direction. The detected maximum value (Kmax) and minimum value (Kmin) are respectively corrected by a maximum value correcting circuit (5) and a minimum value correcting circuit (6) based on the output results of the histogram detecting circuit (2), and output as a corrected maximum value (Lmax) and a corrected minimum value (Lmin). Based on these corrected maximum value (Lmax) and a corrected minimum value (Lmin), an input video luminance signal is corrected. Thus, it is possible to obtain optimal effects of gray-scale correction in accordance with a scene.
