Abstract: Layered glass products such as multilayer glass rods or fibers are formed in a preferably continuous process wherein at least two component glasses are supplied to an annular mixing zone wherein relative movement of the annular surfaces produces spiral layering of the glasses and the formation of a glass product stream having a preselected gradient in composition and glass properties across a diameter thereof.

Abstract: A method is set forth for making polarizing glasses having high dichroic ratios by drawing relatively small silver-containing particles under relatively high stress and elongating such particles during the drawing process without rupturing the glass draw by coating the polarizing glass with a substantially low viscosity skin glass.

Abstract: Method and apparatus is set forth for supporting a laminated extrusion die in such a manner so as to virtually eliminate all tensile stress in the die by applying a compressive force to end portions of die blades, forming said laminated die, parallel to the neutral axis thereof and offset a given distance from the neutral axis toward an outlet face of the die.

Abstract: An insulating contoured window is provided for use with an enclosed chamber such as an evacuated flat plate solar heat collector with the contoured solar window being of minimum thickness and supported solely about its peripheral edge portions. The window is contoured in both its longitudinal and transverse directions, such that in its longitudinal direction the window is composed of a plurality of sinusoidal corrugations whereas in its transverse direction the peaks of such corrugations are contoured in the form of paraboloids so that the structure may withstand the forces generated thereon by the atmosphere.

Abstract: A plurality of cellular shapes for honeycomb structures having cells of uniform size and shape are disclosed having movable expansion joint means built into each individual cell structure, which joints can tolerate large strains without breaking.

Abstract: A gobbing member is operated wholly within the confines of a straight well portion of a glass delivery system, and completely submerged within the molten glass being delivered, such that the flow rate through the delivery orifice of such straight well is linearly related to the speed of said gobbing member independently of the position of such member within the confines of the straight well.

Abstract: TV bulbs are composed of funnels and panels, and the present invention sets forth a novel construction of a funnel for a TV bulb which not only incorporates thinner walls than a conventional funnel, but which also utilizes less total glass when formed into a bulb than a conventional TV bulb, while retaining the required strength and sealing surface area necessary to form an evacuated TV tube when sealed to a viewing panel.
