  • Patent number: 10646920
    Abstract: An exemplary embodiment of the invention provides a method of preparing a reinforced refractory joint between refractory sections of a vessel used for containing or conveying molten metal, e.g. a metal-contacting trough. The method involves introducing a mesh body made of metal wires into a gap between metal-contacting surfaces of adjacent refractory sections of a vessel so that the mesh body is positioned beneath the metal conveying surfaces, and covering the mesh body with a layer of moldable refractory material to seal the gap between the metal-contacting surfaces. Other embodiments relate to a vessel formed by the method and a vessel section with a pre-positioned mesh body suitable for preparing a sealed joint with other such sections.

  • Patent number: 10646924
    Abstract: The present invention is related to additive manufacturing methods and systems using a recoater with in-situ exchangeable recoater blades. Being able to switch out recoater blades in situ, i.e. without stopping the build and opening up the build chamber, is advantageous, especially for larger, more complicated, and/or longer builds. For instance, if a recoater blade becomes damaged, a new one can be readily swapped in. Or if a different material for the object(s) is used during the build, it may be advantageous to switch in a new recoater blade that is made of the new, different material.

  • Patent number: 10646958
    Abstract: A manufacturing method and a manufacturing apparatus for a separator layer-coated electrode are provided capable of shortening the time required to cut out a separator layer-coated electrode with a laser beam. In a cutting process, a laser beam is irradiated to a laser irradiation target portion of a strip-shaped separator layer-coated electrode from a front-side separator layer side to cut a strip-shaped separator layer-coated electrode. Prior to the cutting process, a preheating process is conducted to preheat the front-side separator layer in the laser irradiation target portion.

  • Patent number: 10646960
    Abstract: The present disclosure relates to a powdered bed fusion additive manufacturing (PBFAM) apparatus. The apparatus uses a container for holding a quantity of powdered material. The container has a bottom wall for supporting the powdered material, wherein the bottom wall is made from the same material as the powdered material. A temperature sensing subsystem is coupled to a portion of the container for detecting a temperature of the container. A laser generates an optical beam directed at the powdered material held by the container for melting the powdered material. A controller receives temperature information from the temperature sensing subsystem and determines an absorptivity of the powdered material based on the temperature information.

  • Patent number: 10646961
    Abstract: A laser-machining device includes an arrangement for producing and guiding a working laser beam. The arrangement includes a nozzle having an opening for emission of the working laser beam to a machining zone. An optical axis is defined in the arrangement and at least one element focuses the working laser beam near the opening of the nozzle. The machining process is monitored via at least one group of detector arrangements for a radiation characteristic of the machining process and an associated evaluating unit. The detector arrangements of each group are arranged in a ring shape about the optical axis. The observation direction of the detector arrangements extends, at least in a sub-region, between the focusing element closest to the machining zone and the machining zone, at a polar angle, in relation to the optical axis of the working laser beam.
