Granted: 2008-03-18
Abstract: A molded brake disc having a central hub portion and an annular disc portion extending from the hub portion in a radial outward direction for frictional engagement with brake pads, wherein the disc portion is formed of metal matrix composite having a reinforcing material added to a metal matrix, and the hub portion is formed of metal which is inexpensive as compared to the metal matrix composition. Due to a limited use of the expensive metal matrix composite, the molded brake disc as a whole is inexpensive as compared to a conventional molded brake disc entirely formed of metal matrix composite. Such molded brake disc can readily be formed by an improved injection molding method, wherein a metal matrix composite material in a molten state and a metallic material in a semi-solidified state are supplied into an injection cylinder such that the metal matrix composite material is situated on a gate side adjacent to a gate of a molding die and the metallic material is situated on a piston side adjacent to a piston in the injection cylinder, and the metal matrix composite material and the metallic material are then forced by the piston into a die cavity in the molding die in the order named.

Abstract: L'invention concerne un système de stérilisation et de distribution d'eau utilisée dans des pratiques dentaires et autres actes médicaux. Ce système comprend un réservoir de stérilisation à l'intérieur duquel de l'eau du robinet provenant de l'alimentation des agglomérations ou d'une autre source est stérilisée pour en éliminer les bactéries et autres micro-organismes nocifs. L'eau stérilisée est évacuée vers un réservoir quand le niveau de l'eau dans le réservoir atteint une limite minimale fixée, détectée par une canne de niveau qui commande l'ouverture d'un clapet situé entre le réservoir de stérilisation et le réservoir d'eau. L'eau stérilisée peut être utilisée pour réaliser des pratiques dentaires ou des actes médicaux nécessitant de grandes quantités d'eau (irrigation, refroidissement, etc.). Le système de distribution permet une distribution facultative de l'eau stérilisée par le biais d'un appareil de distribution classique utilisé en pratique dentaire, l'injection de produits désinfectants dans certains dispositifs et systèmes de distribution et la fourniture simultanée d'eau stérilisée à d'autres appareils.

Abstract: Logical coverage areas are dynamically rearranged to meet the traffic needs of a wireless switching system. Further, the logical coverage areas do not have to be initially provisioned during deployment of the wireless switching system since the initial determination of the logical coverage areas is automatically performed. Once the logical coverage areas are established, the logical coverage areas adapt to the changing needs of the community of wireless handsets. A first embodiment allows the base stations to control the rearrangements, and a second embodiment allows a system wireless controller controlling the wireless switching system to control the rearrangements.
