    摘要： The invention includes inventive methods of treating a soot preform. One method includes heating a soot preform to a temperature of less than about 1000 null C. and exposing the preform to a substantially halide free reducing agent. Preferred reducing agents include carbon monoxide and sulfur dioxide. Another inventive method of treating the preform includes exposing the preform, in a furnace, to a substantially non-chlorine containing atmosphere comprising carbon monoxide. The preform is heated to a temperature of at least about 1000null C. Preferably this method is incorporated into the process for making an optical fiber. An additional method of treating the preform includes doping the preform with fluorine and exposing the fluorine doped preform to a substantially chlorine free atmosphere comprising at least carbon monoxide at a temperature of at least 1100null C., thereby reacting excess oxygen present in the furnace.

    摘要： A method for producing a glass sleeve having a first flattened portion and shaping tools for forming such glass sleeves. A method can comprise providing a substantially cylindrical glass tube—optionally polished or otherwise treated to reduce or remove interior imperfections—heating the glass tube to a temperature within the softening range of the glass, introducing one or more shaping tools having a generally D-shaped or generally rectangular cross-section into the enclosed space, and moving the one or more shaping tools against the inner curved surface to deform the tube, forming the first flattened portion. The one or more shaping tools can be made of any suitable material, for example: steel coated with boron nitride; porous graphite or carbon air bearings; or a nickel-based alloy (e.g., Inconel).

    摘要： Mold for manufacturing glass containers such as salad has at least one through hole through their walls with three distinct parts; a die defining the outer shape of the container adapted to receive a gob of glass in a plastic state; a plunger, the inner shape of the container to be molded; and a closing ring. The three parts are pressed onto one another to cause pressing and expansion of the glass gob in the cavity of the mold. The die has a monolithic construction of one piece, and the closing ring and the one-piece die have at least one protruding portion defining the shape of the through hole to be molded and formed in the container.
