  • Patent number: 7735338
    Abstract: The method of making thin glass panes includes conveying a glass melt through a vertical inlet to a drawing tank with a slit nozzle; drawing a glass ribbon downward from the slit nozzle; setting a total throughput by setting length and cross section of the inlet and by heating and cooling the inlet to control glass melt viscosity so that pressure in the inlet decreases; and setting a throughput per unit of length in a lateral direction along the glass ribbon via nozzle system geometry and by heating and cooling of the drawing tank and slit nozzle to control melt viscosity, so that glass does not wet an underside of the slit nozzle near a breaking edge. The setting of the total throughput and the throughput per unit length are largely decoupled to simplify process control. An inventive apparatus for performing the method is also disclosed.

  • Publication number: 20040118161
    Abstract: The invention relates to a method for producing and/or preparing molten glass. The invention is characterised by the following: the molten glass flows in a container in a principal flow direction, the level of the molten glass being at a specific height above the base surface of the container; streams of a free-flowing medium are introduced into the molten glass in such way that said glass flows in spiral paths and that the axes of the spirals run parallel or approximately parallel to the principal flow direction; neighbouring inlet points of the streams are separated by a mutual distance, (viewed from the principal flow direction), of at least 0.5 times the height of the molten glass level.

  • Publication number: 20040065115
    Abstract: The invention relates to a method for producing thin glass panes, especially glass panes with a thickness of below 1 mm, by drawing a thin glass strand vertically downwards. According to the inventive method, a glass melt is fed from a melting bath via a feed to the glass drawing tank that comprises a nozzle system with at least one slotted nozzle. The length and the diameter of the feed as well as the viscosity of the glass melt present in the feed determine the overall throughput. The throughput per length unit in the transverse direction to the glass strand (so-called line throughput) is adjusted via the geometry of the nozzle system and via the viscosity of the glass melt present in the nozzle system. These parameters are adjusted in such a manner that the glass, when leaving the nozzle system, does not wet the bottom of the slotted nozzle in the range of the tearoff edge.

  • Patent number: 6532770
    Abstract: Described are substrates for magnetic media which have excellent surface properties as prepared directly from a slot drawdown glass sheet forming process. The substrate blanks cut directly from the glass sheet, as drawn, require little or no surface treatment for use as substrates for magnetic media, particularly hard disk drives. Also described are methods for preparing such substrates and methods for preparing magnetic media therefrom. Further described are the substrates and magnetic media prepared by such processes.
