Inventor: ROTH ROBERT
IPC: F16L27/073
Filed: 1989-12-22
Abstract: ABSTRACT            Articulated tube connection, in particular for the exhaust pipework of a motor vehicle.       The connection has two inverted tubes  one of which, the outer tube (6)  is enlarged in order to form a casing (8) for housing two support pads (10) which are held tightly between the two tubes and a radial protec-tion (12) of the inner tube. A gasket (14, 15) with a section in the shape of a recumbent V and which has a cylindrical flange for bearing against the inner tube and a convex flange for bearing against the outer tube, is mounted on each of the ends of the casing (8). The two gaskets face in opposite directions and are fitted onto the pads which hold them tightly. The convex flange (18) is preferably spherical only for a part of its length. This spherical part forms the surface for rubbing against the casing and enables a relative displacement of these two members with no risk of the tightness failing.          Fig. 1.

Abstract: BREVET D'INVENTION L'invention a trait au contrôle optique de corps suffisamment transparents, en particulier d'articles tels que des bouteilles ou flacons distribués en file sur un convoyeur à tablier horizontal, devant l'appareil dont chaque émetteur de lumière peut se réduire à un simple écran fournissant un fond lumineux. L'exploration électronique rapide s'effectue par lignes, selon la direction de déplacement sur l'image et s'assortit, sur le récepteur d'un balayage transversal complémentaire, plus lent. On recourt, au premier chef, à un dispositif dont le récepteur, équipé d'une caméra linéaire, combine avec l'objectif de celle-ci et son réseau de cellules photoélectriques, disposé "horizontalement", un système optique de renvoi complétant l'examen par un mouvement de balayage mécanique "vertical". On peut ainsi, à haute cadence, associer contrôle d'aspect et contrôle dimensionnel précis.
