Abstract: Methods and apparatus for manufacturing glass sheets are provided. The apparatus includes an inlet for delivering glass to a trough formed in a refractory body. The lowest point in the trough is located on the end opposite inlet end.

Abstract: A sound-attenuating enclosure for a portable machine. The enclosure includes an inner shell, an outer shell, and a duct. The inner shell includes an inner air inlet opening, and the outer shell includes an outer air inlet opening. The duct connects the outer air inlet opening and the inner air inlet opening, while preventing a line-of-sight between the outer air inlet opening and the inner air inlet opening.

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 pull roll assembly is described herein that is used to draw a glass sheet. The pull roll assembly includes a first roll assembly, a second roll assembly and a device (e.g., differential drive, sensor(s)). The device enables one to control the first and/or second roll assemblies based in part on pulling forces (e.g., glass contact normal force and/or required sheet pulling force) associated with a glass sheet while the glass sheet is being drawn between the first and second roll assemblies. A glass manufacturing system and method for using the pull roll assembly are also described herein.

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.
