20120297836 | PULL-ROLLS FOR USE IN GLASS MANUFACTURING PROCESSES AND METHODS FOR MAKING THE SAME - Pulling rolls for used in forming glass ribbons with reduced defects and cracking are disclosed. In one embodiment, the pulling roll may include a shaft member and a roll assembly. The roll assembly may be positioned on the shaft member for rotation with the shaft member. The roll assembly may include an axially compressed stack of ring elements formed from an inorganic material such as mica paper. The mica paper may include layers of overlapping mica platelets oriented substantially in parallel with one another. A contact surface of the roll assembly may have a Shore D hardness greater than or equal to about 10 and less than or equal to about 60. | 11-29-2012 |
20130224465 | LARGE XENOTIME CERAMIC BLOCK AND DRY PROCESS FOR MAKING THE SAME - A ceramic block consisting essentially of substantially homogeneous (Y | 08-29-2013 |
20140060116 | DOWNSTREAM ROLLS FOR GLASS MANUFACTURE AND METHODS - A downstream roll for glass manufacture comprises at least one millboard piece. At least a portion of an outer peripheral surface of the downstream roll comprises infiltrated ceramic particles. The infiltrated ceramic particles are infiltrated to a depth of about 1 mm to about 10 mm. Further examples of the disclosure include methods for manufacturing a glass ribbon and a downstream roll for glass manufacture. | 03-06-2014 |
20140130550 | PULLING ROLLS WITH SPRING ELEMENTS HAVING INCREASED ANGULAR LENGTH FOR USE IN GLASS MANUFACTURING AND PROCESSES INCORPORATING THE SAME - In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The spring elements project outward from the annular hub such that an end of each spring element is positioned radially outward from a base of each spring element and is circumferentially offset relative to the base of each spring element. | 05-15-2014 |
20140130551 | PULLING ROLLS WITH DEFLECTION LIMITATION FOR USE IN GLASS MANUFACTURING AND PROCESSES INCORPORATING THE SAME - In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk and at least one deflection limiting disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The at least one deflection limiting disk includes at least one deflection limiting element positioned on each deflection limiting disk. The at least one deflection limiting element engages at least a portion of at least one traction disk upon a predetermined amount of inward radial deflection of the plurality of spring elements, thereby limiting the inward radial deflection of the plurality of spring elements. | 05-15-2014 |
20140144183 | GLASS MANUFACTURING APPARATUS AND METHODS - Low-carbon monolithic refractories are provided. Methods of manufacturing glass employing low-carbon monolithic refractories are also provided. Methods and apparatuses for glass manufacture for reducing the formation of carbon dioxide blisters during glass manufacture are also provided. | 05-29-2014 |
