Abstract: Préchauffeur d'air à trois secteurs qui comporte des plaques (42, 44) de secteur entre le secteur (50) d'air primaire et le secteur (48) de gaz de fumée et entre le secteur (52) d'air secondaire et le secteur (48) de gaz de fumée. Lesdites plaques sont de grandes dimensions de manière à fournir des fermetures d'étanchéité radiales doubles. Toutefois, la plaque (46) de secteur entre les compartiments d'air primaire (50) et secondaire (52) est petite et ne fournit qu'une fermeture d'étanchéité radiale simple. Cette plaque (46) de secteur plus petite réduit la chute de pression à travers le préchauffeur d'air, mais entraîne une augmentation des fuites uniquement entre les secteurs d'air. La fermeture d'étanchéité axiale entre les secteurs d'air primaire et secondaire peut être maintenue aux dimensions d'une fermeture d'étanchéité double.

Patent CA-2199089-A1 (CA)
Inventor: WEILER CHARLES A JR
IPC: F16K31/48
Filed: 1997-03-04
Abstract: A fluid control valve includes an adjustable soft start capability. The fluid control valve isolates an input port and connects an outlet port to an exhaust port when the fluid control valve is in its closed position. A system is provided forlocking the fluid control valve in the closed position. When the fluid control valve is moved to an open position, the exhaust port is isolated and full communication between the input port and the outlet port is delayed by a piston which continues to block fluid flow between the input port and the outlet port. An adjustable by-pass passage bleeds pressurized fluid from the input port around the piston to the outlet port until a specified pressure is built up at the outlet port. When the pressure at the outlet port reaches the specified pressure, the piston is moved from a position which blocks the flow from the input port to the outlet port to a position which allows full communication between the input port and the outlet port.

Abstract: L'invention se rapporte à une composition comprenant une résine époxy, un agent de réticulation de la résine époxy se présentant sous la forme d'un anhydre carboxylique, et au moins un composé formant un réseau allyle. Selon l'invention, le composé fonctionnel anhydre est un copolymère d'un anhydre éthyléniquement insaturé et un composé vinylique. Les copolymères d'anhydre maléique et styrène connus sous le nom de SMA de type 1 sont notamment appropriés. Il s'est avéré, de façon inattendue, que la présence d'au moins 2 % en poids de cyanurate triallyle (TAC) entraîne une augmentation de la température de transformation du verre, de sorte que, même avec des composés époxy bifonctionnels simples, on peut obtenir des résines qui ont une température de transition du verre égale et supérieure à 130 ~C. Il s'est également avéré que le traitement de feuilles préimprégnées de résines époxy réticulées à l'aide de copolymères anhydre-vinyle est considérablement amélioré par la présence d'au moins 10 % d'allyle.

Abstract: A well pipe perforating gun (10) is improved by the utilization of a pulverable support structure (14) to hold the explosive shaped charges (18a, 18b, etc.) and the fireset (20). When the gun (10) is fired, the support structure (14) disintegrates substantially into fragments too small to obstruct the flow of oil or natural gas from a surrounding earth formation into or through the well pipe (12) within which the gun is disposed.  Optionally, the support structure (14) is assembled from a number of segments (14a, 14b, etc.) linked together in sequential fashion.

Patent CA-2222052-A1 (CA)
Inventor: BUTLER BOYD L
IPC: F01N1/12
Filed: 1997-11-25
Abstract: A muffler for reducing acoustic noise contained in a gas flow, such as created by internal combustion engines, air compressors, and blower manifolds.  The muffler consists of a conventional sheet metal casing which has an inlet and an outlet at opposite ends thereof.  A flow of gas containing acoustic noise flows from inlet to outlet.  A plurality of spiral acoustic traps, each of which extend from bottom to top of the casing,  have a central axis positioned perpendicular to the gas flow.   An opening in each spiral acoustic trap extends into the gas flow to divert some gas into the trap, wherein the gas flows in a circular path so as to degrade and randomize the sound waves into heat, by utilizing a circular mixing process with increased gas retention time.  Gas is drawn out of the acoustic trap through a series of vent holes in the acoustic trap on the back side of the acoustic trap opposite the opening, by utilizing a venturi effect created by part of the inlet gas flow which is split off into a peripheral gas flow to flow around the acoustic trap through a constricted area just ahead of the vent holes, created by the acoustic trap and the adjacent casing wall or adjacent trap, so as to create a low pressure zone at the vent holes to continuously draw gas out of the acoustic trap.  The acoustic traps may be oriented in a single or multiple linearly extending staggered groups, with in-line or offset inlets and outlets.

Title: Toner cartridge with hopper exit agitator
Inventor: CAMPBELL ALAN STIRLING
IPC: B65D83/06
Filed: 1997-12-19
Abstract: A toner cartridge (1) has a cylindrical toner hopper (61) with a rear wall (61a) defining an output opening well above the lower part of the hopper.  A paddle (63) is rotated in the hopper.  The exit surface (61aaa) declines downward to form a chamber for the toner adder roller (45) and developer roller (43).  This configuration discourages toner from returning to the hopper after it has been electrically charged.  To improve movement of toner past the opening an agitator bar (65) extends across the cartridge near the exit surface.  The bar is pivoted at both ends and has a portion (65a) which extends into the path of the paddle.  As the paddle rotates, it moves the agitator upward until the curved paths of the two members reach separation, at which time the bar drops by gravity.  The bar jars toner loose and eliminates jams of toner.  The flat surface of the bar, when it has been moved up,  partially blocks the exit opening, which desirably limits toner flow.
