Publication number: 20150360990Abstract: Methods for producing glass articles from glass melts are provided that include continuously introducing the glass melt into a stirrer vessel, stirring the glass melt in the stirrer vessel by at least one blade stirrer, continuously discharging the glass melt from the stirrer vessel, and shaping the glass melt to obtain the glass article. In some embodiments, the stirring is sufficient to draw the glass melt located at a surface of the stirrer vessel into the stirrer vessel so that a formation of a surface layer of the glass melt with a different composition from the composition of the glass melt introduced is prevented or at least minimized. In other embodiments, the stirring is sufficient so that the glass melt which is located at a surface in the stirrer vessel is not drawn into the stirrer vessel or is drawn in only insubstantially.Type: ApplicationFiled: June 15, 2015Publication date: December 17, 2015Inventors: Frank-Thomas Lentes, Karin Naumann, Monika Buerkner-Brigaldino, Norbert Greulich-Hickmann, Jan Philipp Steigleder

Patent number: 7934392Abstract: The method of continuously producing flat glass includes rolling a fluid glass sheet between upper and lower shaping rollers to shape and calibrate the glass sheet, generating a respective gas cushion between the fluid glass sheet and each shaping roller from a liquid, controlling the pressure of the gas cushion between the fluid glass sheet and the upper shaping roller to completely prevent contact of the glass sheet with the upper shaping roller, controlling the pressure of the gas cushion between the fluid glass sheet and the lower shaping roller to form a linear contact area between the fluid glass sheet and the lower shaping roller and controlling the contact area width according to speed and viscosity of the glass sheet in order to transport it without slipping and reduce cooling path length.Type: GrantFiled: July 13, 2005Date of Patent: May 3, 2011Assignee: Schott AGInventors: Norbert Greulich-Hickmann, Andreas Langsdorf, Ulrich Lange, Fritz Schroeder

Patent number: 7174745Abstract: An apparatus for press-forming a molten gob made of meltable material, especially of glass or glass ceramics, into a body of specific shape with compression moulds which form with each other a form cavity for receiving the gob. The compression moulds consist at least in the zone of the forming surfaces of an open-pore material and the compression moulds are connected to a pressure gas source in order to produce a gas stream which emerges from the forming surfaces. The open-pore material of the forming surfaces the pores close to the forming surfaces are smaller than the pores remote from the forming surfaces.Type: GrantFiled: August 5, 2002Date of Patent: February 13, 2007Assignee: Schott AGInventors: Christian Kunert, Andreas Langsdorf, Norbert Greulich-Hickmann

Patent number: 7017370Abstract: A method for the homogeneous heating of semitransparent and/or transparent glass and/or glass-ceramic articles using infrared radiation so that the glass and/or glass-ceramic articles undergo heat treatment at between 20 and 3000° C., notably at between 20 and 1705° C. Heating is achieved by a component of infrared radiation which acts directly on the glass and/or glass-ceramic articles and by a component of infrared radiation which acts indirectly on said glass and/or glass-ceramic articles. The radiation component indirectly acting on the glass and/or glass-ceramic articles accounts for more than 50% of total radiation output.Type: GrantFiled: March 22, 2000Date of Patent: March 28, 2006Assignee: Schott AGInventors: Ulrich Fotheringham, Hauke Esemann, Markus Garsche-Andres, Bernd Hoppe, Matthias Brinkmann, Norbert Greulich-Hickmann

Publication number: 20060010915Abstract: A method for making flat glass of good quality by rolling is described, in which a gas cushion is formed between the upper shaping roller and the glass sheet and contact between the lower shaping roller and the glass sheet is limited to a width of from 5 to 30 mm. The resulting flat glass has an upper surface quality that is nearly that of a fire-polished glass surface, while the lower surface has an improved quality that is better than that obtained by the prior art method. Furthermore it is advantageous that the method does not require an increase in the length of the cooling path following the rollers.Type: ApplicationFiled: July 13, 2005Publication date: January 19, 2006Inventors: Norbert Greulich-Hickmann, Andreas Langsdorf, Ulrich Lange, Fritz Schroeder
