  • Patent number: 11097339
    Abstract: A casting plant to produce a cast product with a high quality and a method for managing data for molding the mold and data on the conditions of the molten metal in the casting plant are provided. The controller (11) for the molding unit issues a serial number for the mold to a mold (M). The controller (31) for the unit for conveying the molds shifts the serial number for the mold in accordance with a movement of the mold. It also gathers data on the mold and links the data for molding the mold with the serial number for the mold. When the molten metal is poured from the ladle into the mold, the controller (71) for the unit for pouring the molten metal sends to the computer (91) for controlling the casting plant the serial number for the ladle that is linked with the data on the conditions of the molten metal and that is linked with the serial number for the mold.

  • Patent number: 11084215
    Abstract: A method for fabricating an electrode includes forming a 3D shell having a hollow interior and defining one or more openings, and directing an electrically conductive liquid through at least one of the one or more openings of the 3D shell, such that the 3D shell is at least partially filed with the electrically conductive liquid. The electrically conductive liquid can be caused to solidify within the 3D shell to form a solid electrode, or can remain a liquid to form a liquid electrode. The 3D shell can be formed having the one or more openings using a 3D printing process such as a two-photon writing system. The surface tension of the electrically conductive liquid aids in retaining the electrically conductive liquid within the 3D shell. The electrode can contact a tissue sample through one of the openings in the 3D shell.
