  • Melt overflow system for producing filamentary and film products directly from molten materials
    Patent number: 4930565
    Abstract: A heat extracting substrate is moved along a melt front formed at the edge of the surface of a molten material so that a layer of molten material is deposited on the substrate, cooled and removed from the substrate to form ribbon, filaments, fiber or film directly from the molten material. The edge may be formed by providing an upper edge upon a portion of the wall of a receptacle lower than the top of the receptacle. The molten material may be overflowed over this relatively horizontal edge and against the moving substrate surface.
    Type: Grant
    Filed: November 30, 1988
    Date of Patent: June 5, 1990
    Assignee: Ribbon Technology Corporation
    Inventors: Lloyd E. Hackman, James Dickson, David L. Dunlap, Mark E. Handshey
