Abstract: A forming apparatus (635) is described herein that is used in a glass manufacturing system (100) to form a glass sheet (605). The forming apparatus (635) includes a body (722) having an inlet (702) that receives molten glass (626) which flows into a trough (706) formed in the body (722) and then overflows two top surfaces (726a and 726b) of the trough (706) and runs down two sides (708a and 708b) of the body (722) before fusing together where the two sides (708a and 708b) come together to form a glass sheet (605). The trough (706) has a bottom surface (716) and an embedded object (718) formed thereon that are both sized to cause a desired mass distribution of the molten glass (626) to overflow the top surfaces (726a and 726b) of the trough (706) to enable the production of the glass sheet (605).

Abstract: A method (300) is described herein for producing a glass substrate (105) by melting (302) batch materials to form molten glass (126) and delivering (304) the molten glass (126) to a forming apparatus (135) that has a body (210) with an inlet (136) that receives the molten glass (126) which flows into a trough (137) formed in the body (210) and then overflows two top surfaces (212? and 212?) of the trough (137) and runs down two sides (138? and 138?) of the body (210) before fusing together where the two sides (138? and 138?) come together to form a glass sheet (216). The delivering step (304) also includes a step where the mass flow rate of molten glass (126) that flows over a predetermined length at both end sections of the trough (137) is managed to avoid temporal variations in the glass mass, distribution of the glass mass and thermal energy from the glass mass. In particular, the managing step includes ensuring that more than 17.6 lbs/hour and preferably more than 20.

Abstract: The present invention is directed to the production of articles exhibiting high mechanical strengths which are relatively insensitive to changes in relative humidity. The articles consist essentially of organic and/or inorganic fibers and a binder, the binder being composed of the product of reaction between an organic polycation, and/or an aminosilane, and/or an organic chrome complex and crystals of a lithium and/or sodium water-swelling mica selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolythionite, phlogopite, and fluorphlogopite.
