Patent CA-2535528-A1 (CA)
Title: Vortexer apparatus
Inventor: THUT BRUNO
IPC: F27B3/14
Filed: 2006-02-07
Abstract: The present invention features a vortexer apparatus including a vessel comprising an exterior surface, an interior surface containing fluid and a mouth for receiving material at an upper end portion of the interior surface. In one application the material is metal scrap that is melted in molten metal as the fluid. All components that contact the molten metal are formed of refractory material. An outlet passageway extends downwardly from the interior surface. A vessel inlet opening is located between the exterior and interior surfaces above the outlet passageway. A center line passes through a center of the interior surface and the vessel inlet opening is disposed at a location offset from the center line. A pump is adapted to pump fluid into the vessel effective to form a vortex of fluid in the vessel. The base and impeller are configured and arranged effective to provide molten metal leaving the base outlet with a positive pressure. An outlet conduit extends from the base outlet to near the vessel inlet opening and can be maintained at a temperature above which molten metal solidifies, along its entire length. Instead of the vortexer vessel, the inventive vortexer apparatus may integrate a chamber of a furnace (e.g., a charge well). The chamber may be rectangular or include arcuate portions. Corner inserts may be used to provide the chamber with an oval or generally circular shape that may facilitate the vortex. One feature of the invention is a vortex vessel that includes an offset inlet opening and lower circulation opening. Also featured is a baffle impeller that may be vaned or barrel type. In addition, the invention features a pump having upper and lower impeller chambers separated by a web in the base, and impeller outlets that are isolated from fluid communication with each other.

Title: Procede pour associer a distance un dispositif de communication avec un terminal informatique
Inventor: BOOTON LAURENCE JON
IPC: H04M3/42
Filed: 2004-09-29
Abstract: Dans un environnement d'intégration de téléphonie informatique, afin de réduire le risque d'enregistrement frauduleux ou effectué par inadvertance de l'association d'un terminal informatique d'un utilisateur avec un faux téléphone, par exemple un téléphone différent du téléphone adjacent au terminal informatique ou au téléphone mobile de l'utilisateur, un ordinateur hôte informe l'utilisateur par l'intermédiaire d'un écran d'affichage qu'il doit appeler une extension particulière d'un système de communication autorisé par CTI. Lorsqu'un appel sur cette extension est détectée, le système de commutation le rapporte à l'ordinateur hôte qui stocke un ensemble de caractéristiques concernant le terminal du téléphone appelant comprenant un identificateur de terminal unique. L'utilisateur reçoit alors un second numéro de téléphone par l'intermédiaire du terminal informatique associé au terminal téléphonique qui a été détecté comme le terminal appelant le premier numéro. L'utilisateur peut ensuite composer le second numéro de téléphone, et lorsqu'une demande de liaison avec ce numéro est détectée par le système de commutation, cette demande est transmise à l'ordinateur hôte. L'ordinateur hôte compare ensuite l'ensemble stocké des caractéristiques avec l'ensemble correspondant des caractéristiques du terminal du téléphone appelant. Le processus peut réitérer l'action plusieurs fois, jusqu'à ce que les critères de sécurité soient satisfaits. Une fois que la mise en correspondance a été effectuée, le téléphone est enregistré comme étant associé au terminal informatique. De nombreuses variantes et améliorations fournissent une sécurité améliorée contre les enregistrement frauduleux.

Title: Lancets for bodily fluid sampling supplied on a tape
Inventor: LIST HANS
IPC: A61B17/14
Filed: 2005-04-27
Abstract: A supply of lancets (28) for a multi-use lancing device are carried by a tape (22) and sequentially brought from a storage position to an activating position by advancing the tape around a bend (39). The lancets are non-circular in cross-section along their longitudinal lengths, and in their activating position they extend from the tape such that their sharp tips (31) are available for lancing tissue. The carrying tape can be arranged in reel-to-reel format in a housing having a lancing opening. The lancets can be integral with the tape and activated to move the lancet through the lancing opening by moving the tape along its tape path or by translating a dedicated service loop of the tape. The lancets can also be independent from the tape and activated through the lancing opening by a separate lancing actuator. A test media can be included on the carrying tape and the housing can contain a sensor to yield an integrated lancing and testing device.
