    Abstract: Dispositif de butée à verrouillage magnétique adaptable aux moteurs couplés à courant continu sans balai comprenant : un élément statorique 5 entouré, sur une partie de sa longueur, d'au moins une bobine 4A, 4B et un élément mobile 2 portant au moins un aimant permanent 13A, 13B générant un flux magnétique qui se referme dans ledit élément statorique 5, caractérisé en ce que l'élément statorique 5 est muni d'au moins une paire de butées 3A, 3B pour l'élément mobile et au moins une plaque magnétique 7A, 7B interposée entre ces butées et l'élément statorique 2, chaque butée étant susceptible de recevoir pour appui l'extrémité de l'aimant correspondant 13A, 13B du rotor 2, en fonction du sens de l'effort appliqué sur l'élément mobile 2, un verrouillage de ce dernier 2, en position de butée, étant assuré, par la plaque magnétique 7A, 7B de la butée 3A, 3B.

    Abstract: Magnetic bearing for the active magnetic centring, in at least one axis, of a mobile body according to another body perpendicular to a reference axis (Z-Z) of a body (B,B',B'',BB) which can move with respect to another body (A, A',AA), comprising, on each side of a plane of symmetry perpendicular to the centring axis, and containing the reference axis, at least one permanent magnet (3,3';3-3') magnetised parallel to the reference axis; at least one coil (9,9') wound around a ferromagnetic core (4,4') directed parallel to the reference axis; the magnet (3,3') and the core (4,4') about which the coil (9,9') is wound are gripped between two ferromagnetic plates (1,2; 1',2'; 1-1',2-2') carried by the said other body, whilst the mobile body carries a polar ferromagnetic piece (6,6') adapted so as to turn back on themselves, via the said air gaps (7,8; 7',8'), the magnetic fluxes circulating in the ferromagnetic plates. … …

    Abstract: In order to measure the deformations of an object (10) subjected to stresses, such as a flywheel rotating at high speed inside an evacuated enclosure (14), pulses of light are directed on to the object. These pulses are emitted by a stroboscope (16) synchronised with the speed of rotation of the object. The stationary images thus formed leave the enclosure through a window (24) and pass through a first lens (26) with a long focal length. A graticule (30) is superimposed in a plane (28) on the full-size real images obtained in this way. The images of the object and the graticule are enlarged by a second lens (32). A video camera (34) associated with a screen (36) and a recorder (38) makes it possible directly to display the images of the deformations undergone by the object and/or to store them in memory. … …
