  • Patent number: 11572918
    Abstract: A pivot mechanism for guiding in rotation comprises a mobile element connected to a fixed element through flexible connections; with the flexible elements being configured to guide the mobile element according to a rotational movement in a plane, around a pivoting axis perpendicular to the plane; with each of the flexible connections comprising an intermediary junction provided with an expansion slot, the expansion slot being configured to expand during the rotation of the mobile element, so that the mobile element can pivot according to a second angular amplitude that is greater than a first angular amplitude achieved without said expansion slot; with the intermediary junctions being connected to one another by a coupling member; each of the coupling members being configured so as to prevent a movement out of the plane and a lateral movement in the plane of the mobile element. The pivot mechanism has a very high rotational amplitude.

  • Patent number: 8672536
    Abstract: A mechanical oscillator isochronism corrector comprising a frame (12), a flexible blade (14) integral with the frame to act on a mechanical oscillator at a contact portion (14a) presented by the blade, and a first element for adjusting the pre-stress of the flexible blade including a pre-stress finger (22) acting on the flexible blade, the first adjustment element being integral with the frame.

  • Patent number: 6267363
    Abstract: A flexible pivot with internal pivoting axis comprises two stages that are symmetrical with respect to a median plane perpendicular to the pivoting axis and separated by an external circular recess containing the median plane, each stage comprising an outer annular interface connected by a plurality of radial, flexible guiding arms to a common intermediate cylinder having an axis that is the same as the internal pivoting axis.

  • Patent number: 4813830
    Abstract: In an actuator, a carriage coupled to an item to be displaced with a translatory movement comprises a follower element which defines contact surfaces engaged against the flanks of the thread of a micrometric screw. The contact surfaces co-operate with the thread of the screw only over a small angular portion thereof. The follower element of the carriage is held on the thread of the screw by resilient thrust means acting on the carriage so as to urge it pivotally about an axis (X--X) which is parallel to its direction of translatory movement, being prevented from moving in all the other degrees of freedom. The actuator is especially adapted for use in translator devices in which the level of precision is of the order of a micrometer.

  • Patent number: 4613105
    Abstract: The present invention concerns a device for aligning two optical components.This device comprises a frame composed of a first base plate having two branches which are essentially parallel to each other and a second base plate which also has two branches essentially parallel to each other. One branch carries a first mobile support which is fixed at the end of two flexible strips. The other branch carries a second mobile support being fixed at the ends of two other flexible strips. The two supports carry the two members to be assembled and may be moved relatively to each other in a plane by means of micrometric screws.This device permits to align two members with respect to each other and to fix them in their position.
