Abstract: A metallic sealing assembly between a rotating shaft and a fixed frame comprises: a flexible metallic seal having two tori, inner and outer, that are concentric and of different average diameters, comprising a metal envelope which encases and holds the inner and outer tori; a shaft rotating about an axis of rotation, comprising an annular shoulder against which the seal comes to press; a counter-face, comprising a contact face against which the seal comes to press; a wedge block positioned around the rotating shaft such that the seal is held between the wedge block and the contact face, the wedge block mounted to slide on the rotating shaft; a metal part which forms a cap through which the rotating shaft passes and which is secured to the frame and/or to the counter-face, the rotating shaft being free to rotate with respect to the cap and axially secured to the cap.

Abstract: A subject of the invention is the compounds of formula (I): in which R1, R2, R3, R4 and G have the meanings indicated in the description, their preparation process, their use as medicaments having an antagonist activity on the vitronectin receptor and the pharmaceutical compositions containing them.

Abstract: The periphery of the portion of the valve body of a tire valve which is located on the outside of the wheel rim is composed of elements which are elastic in transverse direction and rigid in longitudinal direction. Tightness is assured by a sealing joint. The valve body may be of a single piece or of two pieces.

Abstract: An inflation valve comprising an outer stem and an inner movable unit is improved by the inner movable unit being confined axially within the tubule by means of a plurality of axially rigid and radially deformable elastic parts in order to permit the installing and removal thereof.

Abstract: Process of fabricating hollow bead rings for the beads of pneumatic tires, said hollow bead rings having a radial cross-section with at least one interior partition which connects together two portions of the outer contour, is improved by using the following operations:(a) extruding, by means of an extruder whose orifice is equipped with a single mandrel, a hollow member whose interior partition is connected to a single one of said portions, the other end of the interior partition being free, and(b) deforming, in one or more steps, the radial cross-section of the hollow member until the free end of the interior partition comes into contact with the other portion of the outer contour.
