Abstract: A method of forming an article such as a light focusing fiber waveguide by applying to a substantially cylindrical starting member a plurality of layers of material, each layer having a progressively lower index of refraction. The assembly so formed is heated and drawn to reduce the cross-sectional area to form a fiber having a stepped radially varying composition. Alternatively, a plurality of layers of material, each having a progressively higher index of refraction are applied to the inner surface of a tubular member. The resulting substantially cylindrical hollow assembly is heated and drawn to reduce the cross-sectional area and to collapse the remaining inner hole to form a fiber having a solid cross-sectional area with a stepped radially varying composition.

Abstract: Apparatus for forming glass articles each having a generally upright wall, such as, for example, skirted glass viewing panels for television picture tubes and particularly including a novel type of ring mold cooperative with a female main mold member to define a mold cavity for forming the articles or panels. The ring mold embodies passages through which vacuum is supplied to the upright wall of an article such as the skirted portion of a panel formed in the mold cavity to support the upright wall or skirted portion until the glass of the article or panel has cooled sufficiently for the upright wall or skirted portion of the formed article or panel to be self-supporting. Means are disclosed for providing vacuum to the passages in the ring mold at a selected time or times following the forming of the article or viewing panel.
