Patent CA-2384133-A1 (CA)
Inventor: SHILLING RICHARD L
IPC: F15D1/02
Filed: 2000-08-23
Abstract: The present invention relates to tubes useful for heat exchangers. The present invention's improved dual radius cross-sectional profile is formed from two sets of circles (100a,b and 200a,b), each set of circles having the same radius but the two sets having different radii. The present invention's dual radius tube non-elliptical profile is therefore defined by two sets of opposing, intersecting arcs (101, 102 and 201, 202) that form a dual radius tubular with two unequal sets of radii of predetermined values. Because each radius within a set of radii is equal, each of the opposing sides within a set of sides is substantially symmetrical, but because each set of sides are arcs of circles the sides are not flattened. The improved tube's overall dual radius cross-sectional profile is therefore neither elliptical, round, rectangular, nor obround. The dual radius profile aids in creating turbulence in a fluid within the tube, enhancing heat transmissivity. The tube may also be twisted into a predetermined number of twists, creating further turbulence in a fluid within and without the tube and further enhancing heat transmissivity.

Title: Simplification de la numerotation pour le telephone
Inventor: FONTES JOAO ANTONIO CRESPO
IPC: H04M1/27485
Filed: 1999-10-14
Abstract: Actuellement, il est nécessaire d'ajouter à un numéro de téléphone l'indicatif local et un préfixe d'opérateur si l'utilisateur souhaite que la communication soit établie par un autre opérateur. S'il réside à proximité d'une autre zone téléphonique voisine vers laquelle il établit quotidiennement des communications, l'utilisateur doit composer l'indicatif local. Aux fins de l'invention, il est désormais possible de composer seulement un chiffre supplémentaire, au lieu de trois chiffres. On peut utiliser aujourd'hui une grande diversité d'opérateurs, le tarif des communications évolue constamment, et l'utilisateur éprouve des difficultés à se tenir informé. Le système de simplification décrit dans l'invention permet d'analyser tous les numéros de téléphone en fonction d'un schéma logique, sur la base des données enregistrées dans la mémoire, mais aussi de compter les chiffres et d'évaluer la durée. On peut ensuite supprimer le chiffre supplémentaire s'il existe, et ajouter, le cas échéant, l'indicatif local, le préfixe de l'opérateur, et aussi choisir l'opérateur. Par ailleurs, il est possible de recevoir un message normalisé, qui est étudié, et qui permet, automatiquement ou sur confirmation de l'utilisateur, de changer d'opérateur pour l'établissement d'une communication.

IPC: E21B27/00
Filed: 2002-09-25
Abstract: An air-tight bailer is filled completely and closed at its open upper end with a flat cap so that no ambient air is trapped in the bailer. A mounting member to which a rope is secured for lowering and lifting the bailer is recessed with respect to the open upper end of the bailer so that it does not interfere with the cap. A disc-shaped protuberance formed on the bottom of the cap fills the recess. An annular groove around the recess receives the rim of the open upper end to enhance an air-tight seal between the cap and the open upper end. In a first embodiment, the bailer is emptied by piercing a thin membrane formed in the cap with a spout device having a trailing end in fluid communication with a container.      A second embodiment eliminates the membrane and the spout device.

Abstract: Le diabète insulino-dépendant (DID) est une maladie auto-immune qui semble être provoquée par un processus inflammatoire dans le pancréas conduisant à une destruction sélective des cellules .beta.. La cyclooxygénase inductible (COX-2) est exprimée dans des états inflammatoires et son produit, la prostaglandine E¿2?(PGE¿2?), est un médiateur important de l'inflammation. L'administration de l'inhibiteur sélectif de COX-2, tel que, par exemple, NS-398, permet de prévenir l'apparition du diabète chez la souris induit par des doses faibles multiples de streptozotocine (STZ). Des observations histologiques indiquent que le traitement à l'aide de NS-398 permet de prévenir la destruction des cellules .beta.induite par la streptozotocine. L'administration reportée (jour 3) de NS-398 constitue également un élément de protection dans ce modèle. Ces résultats démontrent l'importance décisive de l'activité de COX-2 dans la destruction auto-immune des cellules .beta. et permet d'indiquer que l'inhibition de COX-2 devrait constituer une thérapie préventive contre le DID ou d'autres problèmes auto-immuns, y compris le rejet de greffe allogénique. Les inhibiteurs de l'activation de NF-.kappa.B peuvent également être utilisés pour prévenir le DID et le rejet de greffe allogénique.

Title: Semiconductor laser device, and method of manufacturing the same
Inventor: MATSUMURA HIROAKI
IPC: H01S5/20
Filed: 2001-04-25
Abstract: A semiconductor laser device comprises a laminate consisting of a semiconductor layer of first conductivity type, an active layer and a semiconductor layer of second conductivity type different from the first conductivity type. The two semiconductor layers and the active layer are stacked with a waveguide region formed to guide a light beam perpendicular to the width by restricting the light from spreading in the direction of width in the active layer. The waveguide region has first and second waveguide regions. The first waveguide region is a region where light is confined within the limited active layer by a difference in the refractive index between the active layer and the regions on both sides of the active layer by limiting the width of the active layer. The second waveguide region is a region where the light is confined by providing effective difference in refractive index in the active layer.
