  • METHOD FOR THE ADDITIVE MANUFACTURE OF A COMPONENT FULLY OR PARTIALLY MADE UP OF A THREE-DIMENSIONAL LATTICE
    Publication number: 20240149347
    Abstract: A method for manufacturing a part made up entirely or partially of at least one three-dimensional lattice is disclosed. The three-dimensional lattice is produced by additive manufacturing by successive depositions of different layers of additive manufacturing powder and selective consolidation of the layers of powder along at least one path comprising different manufacturing vectors, the three-dimensional lattice comprising at least two layers of parallel strands that are spaced apart from one another, the strands of one layer extending in a longitudinal direction different from the longitudinal direction in which the strands of another layer extend. The manufacturing method provides that each strand is consolidated only via a plurality of manufacturing vectors extending in the longitudinal direction in which the strand extends.

  • Apparatus for manufacturing an optical fiber preform and including a ring for trapping and diffusing light radiation
    Patent number: 6314767
    Abstract: An apparatus and method for manufacturing an optical fiber preform from a tube of vitreous material. A holding device holds the tube during manufacture of the preform and a heater supplies the necessary heat energy for preform manufacturing. A diffuser is disposed adjacently to an end of the tube of vitreous material to trap and diffuse light radiation generated in the tube by the heater. The invention can be used in an apparatus for drawing an optical fiber from a preform. The diffuser traps and diffuses light radiation generated in the optical fiber preform by a fiber drawing oven.

  • Optical fiber preform fabrication installation
    Patent number: 5972115
    Abstract: An installation for fabricating an optical fiber preform includes a reaction tube and an excess silica soot exhaust tube equipped internally with a screw having flat helical threads for removing the excess soot. The screw is a helix hollowed out longitudinally and the installation includes a cylinder housed within the interior passage of the helix, eccentrically disposed within this passage and bearing against the inside surface of the helix. The cylinder is rotated about its axis.
