Abstract: Cette invention se rapporte à un système de filtration à circulation ascendante et à débit élevé, dans lequel on comprime un milieu filtrant, compressible, à boulettes fibreuses de façon à ajuster la porosité et la capacité de rétention dudit milieu dans le lit de filtration et de façon à assurer un gradient de porosité au sein dudit lit, qui se traduit par une décroissance de la porosité suivant une direction opposée à la circulation du fluide de telle sorte que la filtration a lieu de la matière la plus poreuse à la matière la moins poreuse du lit filtrant. On retire les particules les plus grosses au moyen du milieu le plus poreux, puis successivement les particules de plus en plus petites à mesure que le lit filtrant devient moins poreux. Ce système permet de réduire l'aspect trouble des eaux usées municipales d'alimentation d'environ 8 NTU à environ 2 NTU, et ce pour un débit des eaux usées compris approximativement entre 820 et 1230 L/m<2>.mn (20 à 30 gallons/pied<2>.mn), à un taux de compression du lit compris approximativement entre 15 et 40 %, et à un débit de lavage à contre-courant compris approximativement entre 1 et 6 % par rapport à la quantité totale d'eaux usées traversant le filtre.

Abstract: An electrotransport device with a drug delivery regulating apparatus delivers a proper drug dosage rate over time by adapting to variable skin resistance values. The electrotransport device adapts to a decline in skin resistance over a time that the electrotransport device is used, and to different skin resistances at different skin surface locations. One drug delivery regulating apparatus includes a voltage booster, a serially connectable artificial impedance, and a feedback sensor, which are all connected to a controller. This apparatus outputs a load voltage across two electrodes. The controller monitors the output of the feedback sensor to determine the skin resistance, or a load current, or the load voltage. Based on the monitored value, the load voltage across the electrodes is controlled, so that a targeted drug dose rate is maintained even as the initial skin resistance drops over the period that the electrotransport device is used. The artificial impedance is selectively controlled to prevent overdose where the skin resistance falls below a predetermined resistance, such that a load voltage greater than a supply voltage could result in an overdose.

Abstract: A system and method of implementing and provisioning features and there by providing feature services in a call processing environment where features m ay be introduced, changed or removed from outside the code base. Features are introduced or "injected" into the call processing environment using a featur e registry. The feature registry is used to manage feature configuration, behavior and interactions. The code base references the feature registry to apply feature s during operation. In this manner, features can be implemented by reference without modification or rebuilding of the code base. Features can be added, modified or removed without requiring a system upgrade, even while the code base is in operation. The code base uses a structured framework into which features can be introduced by reference using the feature registry. A feature service manage r exclusively controls the feature registry and handles provisioning of features. Feature interaction potential is identified and resolved during feature provisioning. The feature service manager can be configured to enforce feature integrity a nd behaviour rules specific to the call processing product being provisioned.</ SDOAB>

Abstract: Circulation flow apertures in a wellbore pipe, tubing, casing or casing liner screen may be selectively closed by an internal pipe sleeve that is formed of a thin, malleable material. One axial end of the sleeve is flared and secured to the inner bore surface of the pipe as by welding or by clamping between the ends of axially adjacent pipe joints joined by a threaded coupling. The remaining length of the sleeve extends along the pipe and over any pipe apertures to form an annular space between the outer cylinder surface of the sleeve and the inner bore surface of the pipe. A perimeter seal element such as an O-ring is placed around the sleeve outer perimeter beyond the apertures in a direction opposite from the sleeve flare. The flow aperture, in the pipe is closed by a swaging tool that expands the sleeve against the pipe bore wall sufficiently to close the annulus and compress the O-ring seal against the pipe borewall.
