摘要： The present invention relates to a process for manufacturing flat sheets of a glass-based material and to an apparatus therefor. The process comprises providing a glass preform, heating the glass preform in a furnace, forming a gob and a pre-sheet, removing the gob and drawing the glass pre-sheet into a flat glass sheet. Also provided is an apparatus for drawing a glass preform into a glass sheet, the apparatus comprising a draw furnace, stretching arms for stretching and drawing the pre-sheet into a glass sheet, and opposing edge rollers for applying a downward force on the glass sheet. The draw furnace may include a plurality of individual heating elements, the temperature of each heating element capable of being separately controlled. The apparatus may further include an annealing furnace for annealing the glass sheet.

摘要： Disclosed is an optical fiber having a core with an alkali metal oxide dopant in an peak amount greater than about 0.002 wt. % and less than about 0.1 wt. %. The alkali metal oxide concentration varies with a radius of the optical fiber. By appropriately selecting the concentration of alkali metal oxide dopant in the core and the cladding, a low loss optical fiber may be obtained. Also disclosed are several methods of making the optical fiber including the steps of forming an alkali metal oxide-doped rod, and adding additional glass to form a draw perform. Preferably, the draw preform has a final outer dimension (d2), wherein an outer dimension (dl) of the rod is less than or equal to 0.06 times the final outer dimension (d2). In a preferred embodiment, the alkali metal oxide-doped rod is inserted into the centerline hole of a preform to form an assembly.

摘要： The disclosed invention relates to the use of a specific drying agent in a process for drying glass soot preforms. The drying agent includes at least one halide and at least one reducing agent. Preferably, the reducing agent includes a compound that will react with an oxygen by-product of the reaction of the halide and water, or the reaction of the halide and an impurity in the preform. The method includes disposing the soot preform in a furnace, charging the furnace with the drying agent of halide and reducing agent and supplying heat to the furnace. Suitable drying agents for use in the process disclosed include a mixture of Cl2 and CO; a mixture of Cl2, CO and CO2; and POCl3: the latter being an example where the halide and reducing agent are embodied by a single compound.
