  • Publication number: 20250128216
    Abstract: A stirring device for stirring a biphasic fluid has a stirring shaft that can be mounted with a mounting end into a stirring drive. The stirring device also has a first paddle that is arranged in a rotationally fixed manner at or near a stirring end of the stirring shaft that is opposite to the mounting end, and further has a second paddle that is arranged in a rotationally fixed manner at the stirring shaft in between the mounting end and the first paddle. The second paddle is mounted with respect to the stirring shaft in such a manner that it can be displaced in an axial direction along the stirring shaft, which allows for a change of an axial distance between the second paddle and the mounting end of the stirring shaft.

  • Publication number: 20220281166
    Abstract: A Method for additive manufacture of a product containing a layer arrangement step, where a layer of small particles of a product material is arranged, a solidification step, where a laser beam is directed at predefined spots within the layer of small particles for heating and connecting the small particles, resulting a solidified area of product material within the layer, and repeatedly performing the layer arrangement step and the solidification step, where each solidified area of product material of the layer is connected with a previously solidified part of the product until the product is generated by interconnected solidified areas of connected product material. The laser beam is divided into at least two separate subbeams that are directed at separate spots for simultaneously connecting the small particles of the product material at these separate spots. The separate subbeams are directed at separate spots at a distance towards each other.
