| Number | Title | Issue Date |
| 7059154 | Method for making float glass, implementing device and resulting products The present invention relates to a float process for manufacturing glass sheets, in which molten glass is poured onto a liquid support denser than the glass and then the continuous ribbon which forms is advanced toward the downstream end, this process being characte... | 06/13/2006 |
| 6467309 | Method for manufacturing a glass sheet having an uneven surface A heat-resistant pipe is arranged so as to traverse below a glass ribbon in a float bath of molten tin, and bubbles emanate from the heat-resistant pipe, thereby making the bottom surface (which is in contact with the tin) uneven. Alternatively, the botto... | 10/22/2002 |
| 5948133 | Method for holding an edge of a molten glass flow A method for holding an edge of a molten glass flow, comprising forming a molten glass flow by continuously feeding molten glass on a bath surface of molten metal contained in a vessel, holding an edge of the molten glass flow in a width direction thereof... | 09/07/1999 |
| 5328495 | Float-bath ribbon-width control method and system The width of glass ribbon at the hot end of a float bath is controlled to a constant value by raising and lowering a tweel for adjusting the flow of molten glass blank from a smelting furnace to the float bath. The controlled value of the tweel is obtaine... | 07/12/1994 |
| 4940479 | Method for manufacturing float glass A direct current magnetic field is applied to a molten metal bath to control the movement of molten metal. A glass ribbon is formed on the molten metal bath to have a predetermined thickness and is moved on the surface of the molten metal bath controlled ... | 07/10/1990 |
| 4784680 | Method of and apparatus for manufacturing float glass Difference in height is provided between a first surface of a molten metal bath at the upstream side in a vessel and a second surface thereof by means of a linear induction motor. A glass ribbon supplied to the first surface is formed to have a predetermi... | 11/15/1988 |
| 4440559 | Apparatus for sensing a glass ribbon edge and method of use Nip width of a glass ribbon advancing on a molten metal bath is determined by repeatedly, at selected intervals, advancing an edge detector from a first home position toward and into contact with the ribbon edge and then back to a second home position. Th... | 04/03/1984 |
| 4421541 | Process and device for the manufacture of glass by flotation Process for manufacture of plate glass including pouring molten glass onto a bath of molten metal (4) contained in a tank having side wall (1), an inlet wall (2) and an outlet wall (3). The glass is advanced by means to form a glass ribbon (7) and extract... | 12/20/1983 |
| 4395272 | Pressure sizing of float glass A continuous ribbon of glass is reduced in thickness while supported on molten metal by imposing super-atmospheric pressure over a molten glass layer in a chamber where the glass is maintained in contact with the side walls of the chamber. One aspect feat... | 07/26/1983 |
| 4345929 | Method of and apparatus for vertically positioning devices in glass forming chamber A method of vertically positioning ribbon engaging devices in a glass forming chamber includes suspending a contact member within the chamber a known vertical distance relative to the device, moving the contact member toward the surface of a pool of molte... | 08/24/1982 |
| 4339262 | Cooling apparatus for float-glass installation A cooling apparatus for a float-glass installation formed by a pair of pipes providing a path of circulation for a refrigerant adapted to extend through a sidewall of the installation to extend at least partially across a transverse dimension of a ribbon ... | 07/13/1982 |
| 4312656 | Glass ribbon width control method in float process In a float process of flat glass production, the width of a glass ribbon formed by discharging a molten glass onto a molten metal bath is controlled in response to the temperature of a molten glass to be supplied to the molten metal bath by regulating a t... | 01/26/1982 |
| 4260407 | Gas cushioned ice skate edge stretcher Method and apparatus for edge control of glass in the forming chamber. The invention utilizes a blade that is cushioned by gas discharged from its lower edge. The gas cushioned blade does not directly contact the glass thereby minimizing cooling and wear ... | 04/07/1981 |
| 4148622 | Process and apparatus for the production of flat glass by the float glass method An improvement in the process for the production of a glass ribbon by the float glass method, wherein the glass ribbon is formed on a bath of molten metal, caused to float along on top of it and, after being sufficiently hardened, drawn off the bath. The ... | 04/10/1979 |
| 4099950 | Glass ribbon apparatus with tweel employing glassy silica glass contact refractory A float glass forming facility employing a composite tweel and a wetback refractory piece, each having glass contact portions made of a glassy silica such as clear fused quartz, provides for the manufacture of glass which is substantially free of any fine... | 07/11/1978 |
| 4012216 | Apparatus for the production or treatment of flat glass Process and apparatus for the production or treatment of flat glass in an elongate tank containing a bath of molten material. Glass is delivered to the bath, and it is advanced along a path in contact with the bath towards an outlet for the glass from the... | 03/15/1977 |
| 3930829 | Movable dam barriers for use in the manufacture of a glass ribbon on a molten metal bath Movable lateral and longitudinal dam barriers are provided in a glass forming chamber of the type containing a molten metal. The movable lateral dam barriers control longitudinal convection currents in the molten metal to control the temperature of the gl... | 01/06/1976 |
