Title: Systeme de serrage dynamique pour machine a moulage continu
Inventor: GROVE JOHN A
IPC: B22D11/16
Filed: 1998-03-27
Abstract: Ce système de serrage de moule (40) permet de serrer un premier élément de moule sur un second élément de moule d'une machine à moulage continu. Le système comporte une tringle de tensionnement (44) qui est raccordée au premier élément de moule, un châssis support (46) qui est raccordé au second élément de moule, et un élément de cellule de pesage (56) comportant, une partie intérieure (58), une partie extérieure (60) et un dynamomètre (68) permettant de mesurer la force axiale qui se transmet entre les parties inférieure et extérieure (58, 60). La partie intérieure (58) est assujettie à la tringle de tensionnement (44). La partie extérieure (60) subit la force de compression d'un ressort (48) monté entre le châssis support (46) et la partie extérieure (60) de l'élément de cellule de pesage (56). Pour permettre le réglage de la force de serrage, le système comporte également une structure d'opposition au ressort (50) qui est placée de façon à appliquer une force sur la partie extérieure (60) de l'élément de cellule de pesage (56) de façon à contrebalancer la force de compression du ressort (48).
Patent CA-2284994-A1 (CA)
Inventor: FERRIS MICHAEL
IPC: H04L29/08
Filed: 1998-03-30
Abstract: The present invention provides a method and apparatus for integrating applets running on a client with the application logic for applications running on a server. The mechanism of the present invention provides two significant advantages over the prior art: the synchronization of state, and the recognition of user actions in the browser including the invocation of the appropriate application logic in the server. Instead of using the FORM element available in HTML, individual active applets (201) are available and may be created that obtain user input (e.g. a checkbox, textbox, button, etc.).  A hidden applet called the Applet Group Controller (202) is created which handles communication between the applets on the browser and the application logic on the server. The Applet Group Controller (202) maintains an association (302) with each applet (201) that maintains the keys and values of any parameters and variables for the applet (201). In a preferred embodiment, upon the invocation of an event, the association instructs an Action Coordinator (301) to invoke an action. The Action Coordinator (301) obtains and transmits a list of all of the keys and their values to the server. The server invokes the appropriate application logic and transmits the keys and their values (as updated during the execution of the application logic) back to the Action Coordinator (301). The Action Coordinator (301) then pushes the updated values out to the applets (201) (through their Associations (302)) at which time the browser's display is updated with the new values.

Abstract: La présente invention concerne un procédé permettant de placer divers types de cathéters dans l'espace péricardique. Ledit procédé est basé sur le fait que l'oreillette droite constitue une structure à paroi mince et à faible pression dans laquelle on peut pénétrer sans endommager le péricarde ou l'épicarde. On introduit un cathéter guide (401) à travers une veine périphérique choisie afin d'établir un parcours transveineux jusqu'à l'oreillette droite du coeur. On introduit ensuite un cathéter à aiguille (402) à travers le cathéter guide jusque dans l'oreillette droite de manière que l'extrémité distale du cathéter à aiguille (402) est placée contre une paroi de l'oreillette droite. On perce alors la paroi de l'oreillette droite à l'aide du cathéter à aiguille (402). On fait avancer un guide métallique (403) à travers le cathéter à aiguille jusque dans l'espace péricardique. Une fois le guide métallique (403) mis en place, on peut l'utiliser comme un conduit sur lequel on introduit un cathéter désiré afin d'effectuer une procédure médicale déterminée.

Patent CA-2292755-A1 (CA)
Inventor: CORLETT GARY L
IPC: C02F1/465
Filed: 1998-06-04
Abstract: La présente invention permet de récupérer les composants abrasifs et l'eau d'une suspension mécano-chimique aqueuse utilisée pour le polissage de matériaux semiconducteurs. On amène de préférence l'effluent de suspension à un pH neutre, et on le refroidit à une température comprise entre environ 0 ·C et environ 15 ·C. On peut appliquer un potentiel électrique à l'effluent de suspension afin de faciliter l'agglomération et la séparation des particules de matière abrasive dans l'effluent de suspension. Dans un mode de réalisation, on introduit l'effluent de suspension dans une chambre de traitement à une température et une pression ambiantes, et le liquide surnageant séparé de la chambre de traitement est alors soumis à une réduction de pression dans une chambre à vide de manière que le gaz piégé dans le liquide surnageant barbote jusqu'à la surface dudit liquide et que l'on peut séparer et recueillir l'eau et les particules abrasives de l'effluent de suspension. Dans un autre mode de réalisation, on filtre l'effluent de suspension à travers un ou plusieurs ensembles de filtres réversibles auto-nettoyants pour grosses particules.

Title: Pivotable abduction abutment support for wheelchair or the like
Inventor: OBERTELLI BERNARD
IPC: A61G5/10
Filed: 2000-02-09
Abstract: A pivotable abduction abutment support for a wheelchair or the like is disclosed. The support of the invention has a base member adapted to be fastened under the seat of the wheelchair or the like. The support also has a rod having two opposite ends, one end being mounted about a first pivot located on the base member and having a pivoting axis parallel to a front edge of the seat, and the other end having an abutment fastened to it. The rod can pivot between an upstanding position where the rod extends upwardly and substantially vertically, and a released position where the rod extends downwardly. The support further includes a releasable locking mechanism for releasably locking the rod in the upstanding position, which consists of (i) a retaining portion for engaging the front surface of the rod, the retaining portion lying above the first pivot in order to lock the rod in the upstanding position, (ii) at least one arm extending rearwardly from the retaining portion and having a distal end mounted about a second pivot located on the base member rearwardly of the first pivot, and (iii) a spring for biasing the retaining portion against the rod. By manually pivoting the retaining portion away from the rod, the rod is released and free to pivot downwardly. When the rod is pivoted from the released position to the upstanding position, the spring automatically pivots the retaining portion towards the rod to engage the front surface of the rod and thereby lock the rod in the upstanding position. Alternatively, the retaining portion can be adapted to pivot away from the rod about a pivoting axis parallel to the one of the rod or about a vertical pivoting axis.

Title: Central processing hub for multimedia conferencing system
Inventor: WILSON SUSAN ELIZABETH
IPC: H04N7/15
Filed: 2000-08-28
Abstract: A multimedia conferencing system has a plurality of remote user terminals, each of which may be different from any other, and each of which may communicate to a central processing hub using different communications protocols. The central processing hub receives, processes, and sends video and audio data from and to the plurality of remote users, and comprises a media bus for handling video and audio data signals, a packet bus for handling data and control signals, a shelf controller card which issues control messages in keeping with incoming management signals, a bus controller card which provides clock and bus arbitration signals, at least one media processor card for processing video and audio signals, and video encoding means for receiving video data from the one or more media processor cards and delivering video data signals to the packet bus. Video and audio data signals may be received by or delivered from any of the at least one media processor card and the at least one physical interface card. A management node communicates through the shelf controller card to permit management signals to be delivered, which may come from a session manager so as to control the nature of the output video and audio data signals which are sent to the remote user terminals. A video link and a video router permit summing of video data signals, and the resultant summed video data signal is passed to a further video data link via the video router so that the video data signal which is returned to the remote terminals is derived from a cascade of video links.
