摘要： A roll for conveying flat glass at elevated temperatures over extended periods of time without material damage to the supported surface of the glass, and a procedure for preparing such rolls. The roll is built up of thin asbestos discs compressed endwise upon a mandrel. The asbestos is impregnated with a solution of potassium sulfate and then thoroughly dried before the roll is put into use. The potassium sulfate crystals provide lubricity to the roll surface and bind the asbestos fibers together so as to improve the durability of the roll while minimizing damage to the heated glass.

摘要： A furnace for heat treating vertically depending sheet material moving through an enclosed heating chamber, the furnace having entrance and exit openings in opposed end walls and a slot in the roof extending between the openings. The depending sheet material moves through the heating chamber suspended from a trolley supported above the slot, which trolley has hanger rods projecting through the slot. The entrance and exit openings are closed by doors, and an air curtain directed across the slot provides a pressure barrier which, together with the doors, prevents the flow of heated gases from and within the heating chamber.

摘要： A float glass facility which is readily adaptable to the production of float glass ribbons of different thicknesses and particularly to so-called thick or heavy float glass, that is, thicknesses greater than 0.250 inch (6mm). Longitudinally extending fenders are installed to limit the ultimate lateral flow of the glass, and the splay of extension tiles pivotally connected to the restrictor tiles is adjusted to suitably limit the initial spread of the molten glass on the molten bath before it is delivered between the fenders. The adjacent ends of the extension and restrictor tiles meet in an enclosed joint which permits angular adjustment between the members without interference by the molten glass and bath of molten metal.
