Memduh Volkan Demirbas has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230415374
    Abstract: Extrusion dies and methods of manufacturing extrusions dies, the extrusion die including a first plate and a second plate. The first plate has first upstream and downstream surfaces. A first material of the first plate has a first elastic modulus. The first plate includes pins formed between a plurality of slots. The pins and slots define a discharge face for the extrusion die at the first downstream surface of the first plate. The second plate has second upstream and downstream surfaces. The second plate is joined at the second downstream surface to the first upstream surface of the first plate. A second material of the second plate has a second elastic modulus. The second elastic modulus is greater than the first elastic modulus. A plurality of feed holes extend from the second upstream surface of the second plate through the extrusion die into communication with the slots.

  • Publication number: 20210078891
    Abstract: An apparatus and method for producing a glass article includes a melting vessel, a fining vessel located downstream from the melting vessel, and a bubbling vessel that is downstream from the melting vessel and upstream from the fining vessel. The fining vessel may include at least a first zone and a second zone downstream from the first zone, wherein the average temperature of the first zone is higher than the average temperature of the second zone.
