  • Method for monitoring the energy density of a laser beam by image analysis and corresponding device
    Patent number: 10434598
    Abstract: A method for monitoring the energy density of a laser beam using parameters of the laser beam including regularly applying the laser beam to a reference substrate and measuring, with each application, the resulting light intensity; identifying a change in the light intensity on the reference substrate between at least two measurements; and, when the change in the light intensity is higher than a predetermined threshold, determining the unstable parameter or parameters of the energy density of the laser beam.
    Type: Grant

  • Device for damping vibration of a ring for axially retaining turbomachine fan blades
    Patent number: 7458769
    Abstract: A device for damping vibration of a retention ring for axially retaining turbomachine fan blades, the blades being designed to be mounted via their roots on a rotary disk having an annular flange extending axially and provided with a plurality of radial crenellations for coming into contact with a plurality of complementary radial crenellations of a retention ring designed to be mounted around the disk flange, the device comprising an abutment element of elastomer material designed to be received axially between two adjacent crenellations of the flange and two adjacent complementary crenellations of the retention ring, and radially between the flange of the rotary disk and the retention ring, said abutment element presenting contact surfaces for coming into contact with the adjacent crenellations, with the retention ring, and with the flange of the rotary disk.
