  • Patent number: 11680634
    Abstract: A pulley device comprising a pulley and a bearing. The pulley has at least one “C-shaped” pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one recess having in cross-section, a concave internal profile. The pulley part is provided with at least one protruding portion which inwardly extends beyond the inner cylindrical surface of inner portion. The protruding portion is received in a corresponding recess of outer ring so as to block the pulley part with respect to the outer ring in both axial directions.

  • Patent number: 11079582
    Abstract: The present disclosure concerns a broadband hyperspectral imaging spectrophotometer configured to analyze an object and includes an illumination assembly having a source for emitting a light beam and configured so that the light beam scans line by line the object to be analyzed, a focusing mirror, a first mirror folding, and a planar scanning mirror movable in rotation. The illumination assembly, the focusing mirror, the first folding mirror and the planar mirror are arranged to bring the light beam to the object along a line which will be displaced on the object via the scanning mirror. The imaging spectrophotometer further includes two measuring sensors by a distance between the object and the scanning mirror. The focusing mirror is movable in translation to adapt the imager to the measured distance by the measuring sensors.
