20080216515 | Process for Producing Glass Bar - In a heating drawing, a base material glass plate is heated and softened in a heating furnace, and drawn to a desired thickness to form a glass strip. In the heating drawing, the base material glass plate is heated so that the base material glass plate has a U-shaped temperature distribution in a width direction. Such process can be realized through heating by a heating element which has a non-heating portion at a position opposite to a central portion of the base material glass plate in the width direction and a heating portion on both sides of the non-heating portion. Thus provided is a method of manufacturing a glass strip, the method includes heating and softening the base material glass plate, and drawing the base material glass plate to a desirable thickness to form a glass strip, and is capable of manufacturing a thin, rod-like glass strip with an excellent flatness. | 09-11-2008 |
20090007599 | Method and Device For Producing Technical Glass Parts For Optical Applications - The present invention relates to a method for producing a technical glass part, particularly meeting high requirements with respect to contour accuracy and surface quality, particularly a precision lens, wherein a blank including a cast-on section is produced using an injection molding process, wherein the blank is cooled down and subsequently heated, and wherein the blank subsequently is blank molded, particularly on both sides, into a technical glass part meeting high requirements with respect to contour accuracy and surface quality, particularly a precision lens. | 01-08-2009 |
20090084137 | VISIBLE POLARIZING GLASS AND PROCESS - The invention is directed to a silver-containing polarizing boroaluminosilicate glass composition that has been doped with a noble metal selected from the group consisting of Pt, Pd, Os, Ir, Rh and Ru, including mixtures thereof, to nucleate and precipitate silver ions to silver metal without the need for a reducing atmosphere step. The invention is further directed to a method for making the glass composition of the invention. Using the composition and method of the invention, one can prepare a glass having a selected null transmission range. | 04-02-2009 |
20090095022 | THERMAL REFLOW OF GLASS AND FUSED SILICA BODY - Disclosed are synthetic silica glass body with a birefringence pattern having low fast axis direction randomness factor and glass reflow process. The glass reflow process comprises steps of: providing a glass tube having a notch; and thermally reflowing the glass tube to form a glass plate. The process can be advantageously used to produce fused silica glass plate without observable striae when viewed in the direction of optical axis. Also disclosed are optical members comprising the fused silica glass body and a process for reflowing glass cylinders. | 04-16-2009 |
20090113935 | PROCESS FOR PRODUCING GLASS BAR - Included are a reducing-heterogeneous-layer removing process of removing at least a part of a reducing heterogeneous layer in a surface of a plate glass manufactured through a float process, and a heating drawing process of heating and softening the plate glass from which at least the part of the reducing heterogeneous layer is removed in a heating furnace to draw the plate glass to a desirable thickness to form a glass strip. Thus provided is a method of manufacturing a glass strip capable of manufacturing a thin, rod-like glass strip with an excellent flatness even when a plate glass to be subjected to the heating drawing is a plate glass manufactured through the float process. | 05-07-2009 |

20110289968 | Method and Device for Producing Technical Glass Parts for Optical Applications - Disclosed is a method for producing a technical glass part, particularly meeting high requirements with respect to contour accuracy and surface quality, particularly a precision lens, wherein a blank including a cast-on section is produced using an injection molding process, wherein the blank is cooled down and subsequently heated, and wherein the blank subsequently is blank molded, particularly on both sides, into a technical glass part meeting high requirements with respect to contour accuracy and surface quality, particularly a precision lens. | 12-01-2011 |
20120031145 | Method of fabricating decoratively-cracked glass vessels - A method of fabricating a decoratively-cracked glass vessel includes gathering a gob of molten glass and depositing the molten-glass gob into a pre-form mold. A quantity of gas is injected into the pre-form mold in order to form the gob into a pre-form vessel having at least one pre-form wall defining a pre-form vessel exterior surface and a pre-form vessel interior surface defining a pre-form cavity. The self-supporting, but still hot, pre-form vessel is removed from the pre-form mold and a surface of the pre-form vessel is rapidly cooled in order to crack in the cooled surface. The heated pre-form vessel is situated within a finish mold and a quantity of gas is injected into the pre-form cavity in order to seal cracks and form the pre-form vessel into a finished vessel having at least one finished vessel wall defining finished vessel interior and exterior surfaces between which cracks are visible. | 02-09-2012 |
20130125587 | METHODS FOR PRODUCING CRUCIBLES WITH A REDUCED AMOUNT OF BUBBLES - Methods for producing crucibles for holding molten material that contain a reduced amount of gas pockets are disclosed. The methods may involve use of molten silica that may be outgassed prior to or during formation of the crucible. Crucibles produced from such methods and ingots and wafers that are produced from crucibles with a reduced amount of gas pockets are also disclosed. | 05-23-2013 |
20140090420 | Vertical I.S. Machine - A vertical individual section (I.S.) machine for manufacturing glass containers is disclosed in which parisons made in parison molds are lowered into blow molds located under the parison molds without being inverted, where they are blown into glass containers. Optionally, reheat shrouds may be located vertically intermediate the blank molds and the blow molds to reheat the parisons prior to them being blown. The vertical I.S. machine may have multiple sections that are located close adjacent each other, with each section potentially having multiple blank and blow molds. | 04-03-2014 |
