Title: Cage annulaire divisee pour roulement a rouleaux
Inventor: CORBAN EARLE
IPC: F16C9/04
Filed: 1990-01-04
Abstract: Une cage annulaire divisée pour un roulement à rouleaux est constituée de deux parties semi-circulaires. Chaque partie possède des alvéoles 50 destinées à recevoir un ou plusieurs rouleaux. Les alvéoles sont définies par des traverses 52 mutuellement espacées circonférentiellement et par des demi-cercles d'extrémité 58, 60. L'aire de section droite des demi-cercles de chaque partie semi-circulaire de la cage diminue à partir du segment central du demi-cercle, dans le sens circonférentiel, vers chacune de ces extrémités. Cette diminution est matérialisée notamment par la variation continue de la longueur axiale b ou de la dimension radiale h des demi-cercles. Les risques de rupture de fatigue, se produisant généralement dans les segments médians des demi-cercles, sont ainsi diminués. Une telle cage est utilisable notamment dans un roulement de tête de bielle.

Inventor: LAVOISIERE ANDRE
IPC: F04B9/113
Filed: 1990-02-05
Abstract: Pump with a self-reversing piston made to move in a reciprocating rectilinear manner by a source of hydraulic energy including a driving piston which moves with at least one driven piston. Each time it reaches the end of a stroke, the driving piston (1) activates followers (9, 9') in order to move a liquid column (10, 10') which causes a pilot slide valve (13) to be reversed; the latter is designed to reverse the main slide valve (15), which causes the driving piston to move in the other direction, thus ensuring automatic inversion by hydraulic means.

Title: Pipe connector for sealing leaky pipelines
Inventor: IMMANUEL STRAUB
IPC: F16L55/172
Filed: 1991-04-24
Abstract: This connector serves above all to seal a leaky joint between two lengths of pipe. It comprises a body, similar to an opening collar, the ends (1a) of which can be pulled towards one another by clamping means (2, 4) for the purpose of applying a seal in a leaktight manner at C against the pipeline (5, 6). On the ends (9a), the seal is supported by end rings (10) which are radially slit. During the installation of the connector around the pipeline, a cock (tap) (12) causes the internal space of the seal to communicate at C with the outside so that the leaking water can escape without compounding the installation of the connector. This cock is closed at the end of fitting. The invention particularly makes it possible to cure leaks of joints of pipes including a lead sleeve and filling.

Patent FR-2678700-A1 (FR)
Title: Circular closure device
Inventor: JEAN BOKALOT
IPC: F16J13/12
Filed: 1991-07-02
Abstract: A circular closure device, designed particularly to be used in the field of space, comprises a door (32) which is articulated, via a spindle (44) orthogonal to the axis of the device, to a frame (10). A locking hoop (46), supported in rotary fashion by the door (32), may be actuated manually by virtue of handles (80) and of assistance handles (86). The rotation of this hoop (46) in the direction of closure crushes (squashes) inflatable seals to a limited extent (depth), under the effect of ramps (inclines) interposed between the hoop and the frame (10). The locking hoop (46) exhibits, at its centre, portholes (58) and may be immobilised in the closed position by a bolt (88). The pressure induces differential deformations between door and hoop, which has the effect of providing central sealing and of cooperating effectively in locking.
