Abstract: PROBLEM TO BE SOLVED: To provide isopipes which exhibit reduced sag for use in making sheet glass by a fusion process. SOLUTION: The isopipes include a zircon refractory which has a mean creep rate (MCR) at 1,180°C and 1.73 MPa (250 psi) and a 95% confidence band (CB) for the mean creep rate such that the ratio of CB to MCR is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO 2 ) at a concentration greater than 0.2 wt.% and less than 0.4 wt.%. The concentration of the titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibits unacceptable sag prematurely.

Abstract translation: 要解决的问题：提供通过熔融方法制造玻璃板时减少的下垂的等压管。 解决方案：等压槽包括锆石耐火材料，其在1180℃和1.73MPa（250psi）下具有平均蠕变速率（MCR）和平均蠕变速率的95％置信带（CB），使得 CB到MCR小于0.5，MCR和CB都使用幂律模型确定。 锆石耐火材料可以含有浓度大于0.2重量％且小于0.4重量％的二氧化钛（TiO 2 SB 2）。 在这个范围内，二氧化钛的浓度使得锆石耐火材料的平均蠕变速率低于先前用于制造等压槽的锆石耐火材料。 此外，平均蠕变速率的变化也减小，这降低了特定等压槽的锆石耐火材料将具有异常高的蠕变速率并因此过早地显示出不可接受的凹陷的机会。 版权所有（C）2010，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a fuel cell electrolyte sheet with a surface uneven pattern having an allowable distortion of 0.5% or higher in whatever direction of sheet surface. SOLUTION: An unfired flexible ceramic sheet containing a ceramic powder and a thermoplastic organic binder is formed, and at least a portion of the unfired ceramic sheet is heated to soften the binder to form a thermally softened sheet. The softened sheet is reformed to form a pleated sheet, having a sheet uneven array forming multidirectional surface pleats on at least a portion of the sheet. The pleated sheet is fired to remove the binder and sinter the ceramic powder to form a flexible ceramic sheet with the multidirectional surface pleats.

Abstract: A stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell includes a support frame or manifold that supports a peripheral portion of the sheet assembly, a seal that affixes an edge to the frame or manifold, and a stress reducer disposed around the peripheral portion of the electrolyte sheet and the frame or manifold that reduces tensile stress in the peripheral portion of the electrolyte sheet when the peripheral portion is bent by pressure differentials or thermal differential expansion and mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces. The stress reducer is either a convex curved surface on the frame or manifold that makes area contact with the peripheral portion when it bends or a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending.

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 stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell is provided that includes a support frame or manifold having an inner edge portion that supports a peripheral portion of the sheet assembly, a seal that affixes an edge of the peripheral portion to the frame or manifold, and a stress reducer disposed around the peripheral portion of the electrolyte sheet and the frame or manifold that reduces tensile stress in the peripheral portion of the electrolyte sheet when the peripheral portion is bent by pressure differentials or thermal differential expansion. The stress reducer is at least one of a convex curved surface on the inner edge portion of the frame or manifold that makes area contact with the peripheral portion when it bends in response to a pressure differential or thermal differential expansion, and a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending. The stress reducing mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces.

Abstract: Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180 °C and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (Ti02) at a concentration greater than 0.2 wt.% and less than 0.4 wt.%. A concentration of titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibit unacceptable sag prematurely.
