Title: Phenylindoles pour le traitement de l'infection par le vih
Inventor: LA COLLA PAOLO
IPC: C07D209/20
Filed: 2002-04-11
Granted: 2009-11-17

Patent CA-2446153-C (CA)
Title: Procede de fabrication d'un element de renfort pour un tuyau flexible
Inventor: WEDEL-HEINEN JAKOB
IPC: F16L59/153
Filed: 2002-05-23
Granted: 2009-07-21
Abstract: Afin de fabriquer des couches de renfort pour tuyaux flexibles capables d'absorber des forces de compression ou de tension et utilisés dans le transport de pétrole et de gaz, on applique une matière thermoplastique sur une couche leur conférant une résistance. Ces couches sont enroulées sur des bobines et laminées après débobinage par application de chaleur, puis directement appliquées sur le tuyau flexible. La couche conférant de la résistance est constituée d'un polymère renforcé avec au moins 20 % en volume de fibres. La matière thermoplastique est de type réversible, à savoir elle peut passer d'un état relativement doux, mais non collant à un état collant grâce aux variations de température. Ce procédé permet de fabriquer des renforts très résistants pour tes tuyaux flexibles qui ne peuvent être fabriqués avec une matière solide, comme l'acier, étant donné que le façonnage nécessite des forces importantes de fléchissement pour le préformage. Par ailleurs, on prévoit un élément de renfort capable de résister à des charges de choc instantanées grâce à la protection qu'assure la matière thermoplastique.

Title: Valves and suction catheter assemblies
Inventor: MACMILLAN NICHOLAS PAUL
IPC: A61M16/04
Filed: 2004-02-03
Granted: 2011-06-07
Abstract: Conventional closed system suction catheters have a valve with a housing within which a valve member is movable to control suction applied by the catheter. In the present invention the outlet bore is inclined at an angle to the inlet bore and opens into it via an aperture. A valve member comprises a rod member and a manually actuable plate extending longitudinally in an external channel along the housing between two walls. The rod member supports a resilient sleeve and its forward end is urged, by a spring, to engage a tapered seal within the housing forwardly of the aperture, thereby blocking flow through the valve. The valve is opened by sliding the plate rearwardly so that the valve member moves rearwardly of the aperture. A locking cap can be twisted to prevent movement of the valve member from its closed position.
Patent CA-2456829-C (CA)
Title: Reference control for high-sensitivity c-reactive protein testing
Inventor: EBRAHIM ALIREZA
IPC: C07K1/16
Filed: 2002-07-17
Granted: 2011-02-22
Abstract: Low-concentration reference controls for C-reactive protein assays are prepared from higher-level starting materials by simple filtration using silica-type filter media formerly used for removing lipids. This process avoids the need for antibodies to capture the protein and resuspend it. Surprisingly, the removal of CRP by the silica-type filter media is selective toward CRP, having little or negligible effect on other proteins in the starting matrix, and accordingly little or negligible change in the total protein content.

Abstract: La présente invention se rapporte à une pompe à vide permettant de pomper des solides, des liquides et des gaz, ou toutes compositions de tels milieux et comportant une unité de commande (40) raccordée à un système de pompage pouvant être désaccouplé manuellement. Le système de pompage est composé d'une cartouche à deux ou trois chambres (1, 18, 21) permettant de séparer les uns des autres des solides, des liquides et des gaz. Une membrane très souple (24), qui est fixée à la cartouche est scellée circonférentiellement à cette dernière, facilite cette séparation, lors du mouvement alternatif et du pompage. Les composants du système de pompage sont conçus pour être jetables et la cartouche à deux ou trois chambres permet d'obtenir un système de pompage très efficace qui est considérablement plus compact que ceux connus à ce jour. Cette pompe s'avère particulièrement utile pour les applications médicales.

Abstract: Fe-Cr alloy billet manufacturing method according to the present invention, since the blooming is carried out with the high reduction rate surface of the cast steel covered with a scale layer of a large area rate as 70 % or more and without the descaling applied, can reduce the indentation and inclusion of the scale. Thereby, in the case of a billet for use in seamless steel pipes being manufactured from a steel strip of a Fe-Cr alloy, surface treatment before tube-making can be largely reduced. Thereby, when the Fe-Cr alloy billet is adopted in manufacturing seamless steel pipes, since even the Fe-Cr alloy steel pipe relatively hard to process can be manufactured at low manufacturing cost and efficiently, it can be widely applied in a field of manufacturing hot seamless steel pipes.

Abstract: A method and mobile device that self-terminates a media service if an out-of- coverage condition is detected. The media service operates on top of a connectionless peer-to-peer packet-based transport protocol. The out-of-coverage condition may relate to the mobile device itself or to a remote mobile device engaged in the media service. The loss of coverage by the remote mobile device may be detected by observing whether the remote mobile device has failed to send any data packets for more than a predetermined period of time. If an out-of-coverage situation is detected, then the method or device initiates service cancellation or release.
