Abstract: A method of forming an article such as an optical waveguide filament by disposing a draw blank in a cylindrical muffle. The muffle is heated to a temperature sufficient to cause a first end of the blank to reach the drawing temperature of the material thereof. A filament is drawn from the first end of the blank while a helium-containing gas flows through the muffle in such a direction that it is exhausted from that end of the muffle from which the filament is being drawn.

Abstract: A method of making solid glass articles by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P.sub.2 O.sub.5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.

Abstract: A substantially continuous method for drying, consolidating and drawing an optical waveguide preform is disclosed. A porous soot preform suspended from a substantially hollow longitudinal preform handle having a longitudinal aperture therein is provided. The end of the hollow preform handle is connected to a source of gaseous drying medium, and a quantity of the gaseous drying medium is flowed through the aperture in the porous soot preform and through the porous walls of the preform thereby drying the preform structure. The extending end of the porous soot preform is heated to the consolidation temperature of the materials thereof to progressively consolidate the preform from the extending end thereof. The consolidated end of the preform is further heated to the drawing temperature of the materials thereof and a filament is drawn from the extending end of the consolidated preform.

Abstract: A method of making glass optical waveguides by the flame hydrolysis technique. Particles of glass soot produced by flame hydrolysis are deposited on the outside surface of a mandrel to form a porous preform. The soot particles closer to the mandrel have a refractive index greater than that of the soot disposed toward the outer surface of the preform. The mandrel is removed and the resultant hollow soot preform is supported in a draw furnace through which a helium-rich gas flows. The preform is heated to a temperature sufficient to cause said soot to consolidate and simultaneously permit an optical waveguide filament to be drawn therefrom.

Abstract: An apparatus is disclosed for drawing glass optical waveguide filaments having minimal diameter variation. A draw blank is supported within an elongated, heated, tubular muffle which heats the blank to its draw temperature. Gas is supplied to that end of the muffle opposite that from which the filament is drawn. A cylindrically shaped member at least 10 cm long is disposed adjacent to the end of the blank opposite the filament to form with the inner wall of the muffle a thin, cylindrically-shaped channel through which the gas must flow. The gas stream is thus uniformly heated at the time that it reaches the root of the filament so that diameter variations due to gas turbulence are minimized.
