Title: Panel, kit and method for forming a stone masonry wall
Inventor: BOUCHARD MICHEL
IPC: E04F13/08
Filed: 2002-05-22
Granted: 2006-08-22
Abstract: A panel for forming a masonry wall on a building surface, comprising a back face for covering the building surface, opposite edges and a front face with a predetermined pattern of first and second depressions. The first depressions are shaped and sized for receiving masonry pieces as a whole whereas the second depressions, which intersect the opposite edges, are shaped and sized for receiving parts of masonry pieces, so that, when the panel is mounted side by side with a complementary panel, some masonry pieces bridge both panels by means of the second depressions. The panel makes it possible for an unskilled worker to build relatively rapidly a masonry work having a complex predetermined pattern of masonry pieces. Thanks to the second depressions that make it possible for some pieces of masonry to bridge panels mounted side by side, the general arrangement of pieces, when completed does not look like a series of individual panels but rather look continuous.

Inventor: STUTTAFORD PETER J
IPC: F23R3/34
Filed: 2002-07-08
Granted: 2010-08-03
Abstract: A cyclone combustor (10) uses a novel pre-mixture injection scheme to optimize performance. The cyclone combustor includes a cylindrical combustor can (12) and three fuel/air premixing tubes (30) entering the combustor can radially, with a tangential offset. The tangential offset is designed to provide an optimized circulation in the combustor can for improvement of liner life span, flame stability and engine turn-down. The ignition (46) and pilot fuel systems are placed to take advantage of the premixing tube entry locations and the tangential direction of the mixture flow momentum in the combustor can. The special combination of the parallel axes (14,36) of the combustor can and the mixing tubes provides a right angle between an outlet section (34) and the major tube section (32) of each premixing tube. The cyclone combustor of the present invention can meet the requirements for low NOx and CO emissions.

Abstract: On présente une cloison séparatrice de piles à combustible à faible coût ayant un substrat métallique qui a la capacité de maintenir de façon stable une faible résistance électrique (haute conductivité électrique) et une haute résistance à la corrosion durant une longue période. La cloison séparatrice comporte un substrat métallique ayant une pellicule d'oxyde formant une surface sur le substrat et produite par une oxydation d'un métal du substrat, et une mince pellicule conductrice d'électricité' formée sur une surface de la pellicule d'oxyde du substrat. Grâce à cette construction, une faible résistance électrique (haute conductivité électrique) est produite par la mince pellicule conductrice d'électricité. Par ailleurs, même si la mince pellicule conductrice d'électricité a des trous d'épingle, le film d'oxyde empêche ou réduit de façon importante l'élution à partir du substrat de la cloison séparatrice, produisant ainsi une haute résistance à la corrosion. De plus, puisque la pellicule d'oxyde est formée par l'oxydation du substrat, la pellicule d'oxyde peut être formée à partir d'un procédé de moulage inférieur comparativement à une pellicule d'oxyde formée à partir d'un métal différent.

Abstract: Selon un mode de réalisation, l'objet de la présente invention est un dispositif de sculpture et de façonnage polyvalent commandé par processeur ("machine PCCMPS"), lequel dispositif est compact, peu coûteux, léger, polyvalent et facile à utiliser. Cette machine PCCMPS, selon un mode de réalisation de cette invention, est conçue, en partie, de la même manière que les raboteuses à bois portatives classiques que l'on trouve dans le commerce et les micro-imprimantes à jet d'encre et laser omniprésentes. Les pièces à usiner sont introduites dans la machine PCCMPS dans un sens horizontal. Cette machine PCCMPS comprend une tête de coupe motorisée pouvant alimenter des éléments amovibles servant à percer, couper, façonner et défoncer une pièce à usiner sous la commande d'un processeur et d'un ordinateur. La tête de coupe peut être translatée, sous la commande d'un processeur, selon un mouvement de va-et-vient sur la surface de la pièce à usiner dans un sens perpendiculaire à celui dans lequel la pièce à usiner est introduite dans la machine PCCMPS et déplacée par des rouleaux motorisés. Cette tête de coupe peut être translatée vers le haut et vers le bas, dans un sens vertical, de manière sensiblement perpendiculaire à la surface de la pièce à usiner. Le processeur peut ainsi positionner un élément coupant à un emplacement quelconque sur une surface, à proximité de la surface ou à l'intérieur de la pièce à usiner, par une combinaison de translations latérales et verticales de la tête de coupe et par une translation horizontale de la pièce à usiner. Le processeur peut aussi commander la vitesse à laquelle l'élément tourne lorsque l'ordinateur déplace l'élément rotatif d'une position à une autre par rapport à la surface de la pièce à usiner afin que celui-ci sculpte, façonne et élabore des motifs tridimensionnels sur la pièce à usiner.

Title: Method for delivering data over a network
Inventor: CHAN GIN-MAN
IPC: H04N7/173
Filed: 2002-07-29
Granted: 2009-10-20
Abstract: A new method and system for delivering data over a network to a large number of clients, which may be suitable for building large-scale Video-on-Demand (VOD) systems. In current VOD systems, the client may suffer from a long latency before starting to receive the requested data that is capable of providing sufficient interactive functions, or the reverse, without significantly increasing the network load.  The method utilizes two groups of data streams, one responsible for minimizing latency while the other one provides the required interactive functions. In the anti-latency data group, uniform, non-uniform or hierarchical staggered stream intervals may be used.  The system may have a relatively small startup latency while users may enjoy most of the interactive functions that are typical of video recorders. Furthermore, the method and system may also be able to maintain the number of data streams, or the bandwidth, required.

Abstract: The invention relates to a method and device for controlling the attitude of a satellite comprising at least four control moment gyros (10a 10d) having respective gyro wheels (12). The gyro wheels are mounted on gimbals that can be moved (14) around axes which are parallel (18) to one or other of only two different directions, said directions being fixed in relation to the satellite. For this purpose, the attitude of the satellite is measured using sensors that are disposed on board the satellite; the control torque required to perform an attitude reorientation manoeuvre is calculated; a local linearisation calculation is performed based on the pseudo-inverse of the Jacobian matrix of the function linking the orientations of the gimbals of the gyrodynes at the total kinetic moment of the cluster in order to determine a new orientation for said gimbals; and the precession speeds of at least one of the gimbals of the gyrodynes supplying the control torque are controlled in order to produce the desired configuration. The calculation is performed by applying a cluster configuration search constraint which is removed from the singular configurations by division, between the two groups of gyrodynes, of the component of the total kinetic moment of the cluster which is simultaneously perpendicular to both directions.

Abstract: Dans le domaine du diagnostic et des procédures chirurgicales côloniques, le manque de moyens optimaux disponibles pour le nettoyage du côlon constitue un obstacle. Il a fallu trouver un compromis entre des solutions hyperosmotiques, solides ou à volume réduit, pratiques mais désagréables, qui provoquent d'importants déséquilibres fluidiques et électrolytiques chez les patients et des solutions iso-osmotiques, à grand volume, difficiles à consommer. L'invention décrit une solution hyperosmotique à volume réduit constituée de sels de sulfate avec et sans polyéthylèneglycol. Contrairement à ce qui était le cas dans la technique antérieure, cette composition est utile pour le nettoyage des intestins et, à volumes réduits, constitue un laxatif efficace, sans entraîner de changements significatifs du point de vue clinique dans la fonction corporelle.
