  • Patent number: 11718044
    Abstract: An assembly is provided for induction welding. This induction welding assembly includes a fixture. The fixture includes a first support structure and a second support structure. The second support structure includes a frame and a plurality of trunks. Each of the trunks is connected to and repositionable on the frame. The fixture is configured to secure a workpiece vertically between the first support structure and the second support structure using the trunks during induction welding of the workpiece.
    Type: Grant
    Filed: June 7, 2021
    Date of Patent: August 8, 2023
    Assignee: Rohr, Inc.

  • Patent number: 11237386
    Abstract: Various arrangements and methods are disclosed for forming one or more perforations on a substrate surface using a laser system, at least one rotating polygon mirror, and at least one other movable mirror. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface by incrementing (e.g., moving) a first mirror between a plurality of fixed (e.g., pointing) positions. A rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate using a first mirror that is maintained in a fixed (e.g., pointing) position. A first rotating polygon mirror and a second rotating polygon mirror may be used to define a plurality of perforations in a row set or band on a substrate surface, where the first and second polygon mirrors are used to define an extent of a given perforation in two dimensions on the substrate.

  • Publication number: 20210283719
    Abstract: A perforation system is disclosed that utilizes an optical beamlet generator and a scanner (e.g., at least two moveable mirrors). The optical beamlet generator may be a lenslet array or a diffractive optical element. The optical beamlet generator outputs a plurality of beamlets from a single input laser beam. These beamlets are moved in at least two dimensions relative to a surface of a substrate to form perforations in the substrate.
