  • Publication number: 20240317626
    Abstract: Proposed is a thin glass plate processing apparatus and method. More particularly, proposed is a thin glass plate processing apparatus and method, in which at least a side of a heating part presses a glass plate on a jig with a substantially uniform pressure along a processing orthogonal direction, thereby constantly controlling the amount of glass removed during a heat chamfering process of the glass plate, and at the same time, the center of the jig is accurately measured when setting a processing path of the heating part, thereby precisely setting the processing path.

  • Publication number: 20140110267
    Abstract: A process and an anode for the production of nitrogen trifluoride or fluorine where the anode in the electrolytic cell is made primarily from mesocarbon microbeads. The mesocarbon microbead anodes minimize the production of CF4 and improve the purity of the nitrogen trifluoride or fluorine gas produced. Additionally, the anodes may be molded, instead of extruded or machined, providing for improved dimensional and mechanical integrity of the anode.

  • Publication number: 20140110269
    Abstract: A process and an anode for the production of nitrogen trifluoride or fluorine where the anode in the electrolytic cell is made primarily from parallel ordered anisotropic carbon, including needle coke and/or mesocarbon microbeads. The parallel ordered anisotropic carbon anodes minimize the production of CF4 and improve the purity of the nitrogen trifluoride or fluorine gas produced. Additionally, the anodes may be molded, instead of extruded or machined, providing for improved dimensional and mechanical integrity of the anode.
