Patent CA-2458675-A1 (CA)
Inventor: SCHEUERMANN STEPHEN J
IPC: A61B17/34
Filed: 2002-08-15
Abstract: L'invention concerne un trocart chirurgical (10) doté d'un obturateur (14) et d'une canule (12). Ce trocart demande moins de force pour être inséré et extrait des tissus. La canule comprend un ensemble de tête (18) et l'obturateur comprend un ensemble de bouchon (22) qui présente des surfaces coopérantes qui appuient l'une contre l'autre de telle sorte que lorsque l'obturateur tourne autour de son axe (25), l'obturateur est dévié dans le sens axial (27), à l'intérieur de la canule, et peut ainsi être retiré des tissus dans lesquels il est inséré. La pointe (20) de l'obturateur et l'extrémité (64) de la canule sont conçues pour minimiser l'endommagement des tissus et l'effort d'insertion en fournissant une transition à surface lisse sans élément. Selon un aspect de l'invention, la pointe de la canule est lisse, continue et souple et peut dévier dans le sens radial lorsque l'obturateur de diamètre supérieur est inséré ou retiré dans la canule. Selon un autre aspect, la déviation axiale de l'obturateur et la tête flexible de la canule coopèrent et l'obturateur peut être dévié dans le sens axial et retiré de la canule et des tissus dans lesquels l'obturateur est inséré par une simple torsion de l'obturateur. Selon un autre aspect de l'invention, une canule présente un élément d'étanchéité élastique qui réduit le risque de fuite de fluide pendant l'insertion ou le retrait d'un obturateur.

Title: Tin-zinc lead-free solder, its mixture, and solder-joined part
Inventor: TANAKA HIROTAKA
IPC: B23K35/14
Filed: 2002-11-18
Abstract: A tin-zinc lead-free solder contains tin as a main component and essentially at least 6-10 weight% of zinc. A protective film of magnesium oxide is formed on the surface of the solder. The solder also contains 0.0015 to 0.1 weight% of magnesium, at which percentage the oxide protective film can be broken when the solder is melted. While a paste of this solder is stored, the magnesium oxide protective film formed on the solder particles protects the inside of the solder particles and suppresses the reaction between the zinc and an activator to prolong the shelf life. The oxide protective film is subject to breakage when the solder is heated and melted to maintain the favorable wettability.

Title: Phase split structure of multiphase superconducting cable
Inventor: TAKAHASHI YOSHIHISA
IPC: H01F6/06
Filed: 2004-05-26
Abstract: A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and a shield connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.

Title: Method and apparatus for chilling draught beverages
Inventor: CHIUSOLO SAM
IPC: B67D7/80
Filed: 2004-09-23
Abstract: The invention described as a booster, provides for a means to chill a draught beverage at a point between its storage container and dispensing faucet. The Booster is comprised of an enclosed tank, which contains a heat exchange mechanism and a beverage storage reservoir. Two cooling liquid lines are attached to the Booster. One of these cooling liquid lines provides for the flow of cooling liquid into the Booster while the other cooling liquid line provides for the flow of cooling liquid from the Booster.  The cooling liquid enters the Booster and flows over the beverage storage reservoir prior to flowing over and into the heat exchange mechanism. The cooling liquid exits directly from the heat exchange mechanism to an internal line that is connected to an exit port of the Booster. Two beverage lines are also attached to the Booster. One beverage line brings the beverage into the Booster while the other allows for the beverage to exit from the Booster. The beverage, upon entering the Booster, flows directly into the heat exchange mechanism whereupon the cooling liquid chills it. The beverage flows from the heat exchange mechanism into the beverage storage reservoir where it is further chilled and maintained at the desired temperature.
