Abstract: A diaphragm type flush valve for use with toilet devices such as urinals and water closets includes a body having an inlet and an outlet, a valve seat between the inlet and outlet, and a valve movable to a closing position on the valve seat to stop the flow between the inlet and outlet. The valve member includes a diaphragm peripherally attached to the body and a disc positioned on top of the diaphragm. There is a guide extending downwardly from the diaphragm. The disc is attached to the guide and functions to secure the diaphragm, disc and guide into the valve member. The disc includes a rigid body and a seal member, with the seal member having a portion on an upper surface of the disc for sealing contact with a relief valve, and a portion on a lower surface of the disc for contact with the diaphragm. The disc is attached to the guide through a one-way clutch which permits relative rotation of the disc and guide in one direction during assembly, and prevents relative rotation in the opposite direction after assembly.

Abstract: L'invention se rapporte à un écarteur vertébral (1, 80) conçu pour être inclus dans un espace discal afin de restaurer et/ou maintenir une hauteur d'espace discal et une orientation spinale souhaitées. Ledit écarteur présente un corps de base allongé (2, 82) ayant une forme généralement lenticulaire donnée par des surfaces convexes supérieure et inférieure (24, 26, 86 et 87). Des surfaces portantes (8, 8', 9, 9', 98 et 100) sont situées sur les surfaces des bords transversaux des parois terminales (6, 7, 94 et 96). Des rainures (16, 16' et 104) sont ménagées dans les surfaces supérieure et inférieure situées entre les surfaces portantes. L'écarteur (1, 80) peut être préparé à partir d'une grande variété de matières et notamment de matières métalliques, de matières synthétiques, de matières polymères, de matières céramiques et de matières composites incluant des matières renforcées telles que des matières renforcées par du verre, des fibres et/ou des fibres de carbone (CFRP). Ces matières préférées pour la fabrication d'écarteurs permettent de réduire les coûts, d'accroître la durée de vie et d'assurer un excellente compatibilité physiologique. La matière non métallique peut être sélectionnée de manière à être une matière sensiblement permanente, une matière biodégradable ou une matière bio-érodable. En outre, la matière de l'écarteur peut également être choisie de manière à être opaque aux rayons X pour faciliter le contrôle de l'interposition osseuse à la fois dans l'écarteur et entre les plaques terminales opposées des vertèbres adjacentes.
