Patent number: 8074518Abstract: Systems (50) and methods for measuring and displaying a visual and/or graphical representation of the specific modulus (E/?) of a cellular ceramic body (10), such as those used to form particulate filters, are disclosed. The ultrasonic measurement system employs an ultrasonic transmitter (52T) and an ultrasonic receiver (52R) adjacent to, but spaced apart from respective ends (16, 18) of the ceramic body. Multiple ultrasonic waves (80) are sent through corresponding multiple longitudinal portions (12P) of the honeycomb structure (12), where adjacent longitudinal portions overlap. Time of flight (TOF) measurements (TOF1, TOF2), along with other parameters describing the ceramic body, allow for the measurement of the sonic speed (cmat) of the ultrasonic waves that pass through the ceramic body as well as the attenuation (IR). The specific modulus is then calculated from the square of the sonic speed (C2mat).Type: GrantFiled: August 25, 2008Date of Patent: December 13, 2011Assignee: Corning IncorporatedInventors: John David Helfinstine, Robert A McIntosh, Lisa M Noni, Zhiqiang Shi, Sujanto Widjaja, David John Worthey

Patent number: 8063560Abstract: A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display is manufactured by providing a first substrate plate and a second substrate plate and depositing a frit onto the second substrate plate. OLEDs are deposited on the first substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the OLEDs. The frit is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source heats the frit, it softens and forms a bond. This enables the frit to melt and form the hermetic seal while avoiding thermal damage to the OLEDs.Type: GrantFiled: September 15, 2006Date of Patent: November 22, 2011Assignee: Corning IncorporatedInventors: Bruce G. Aitken, Joel P. Carberry, Steven E. DeMartino, Henry E. Hagy, Lisa A. Lamberson, Richard J. Miller, II, Robert Morena, Joseph F. Schroeder, III, Alexander Streltsov, Sujanto Widjaja

Publication number: 20100297534Abstract: Disclosed are seals and seal structures for use in electrochemical devices such as solid oxide fuel cell devices. Exemplary seal structures are configured such that at least a portion of the interface between the seal and electrolyte sheet deviates from planarity by extending either (i) upwardly and inwardly (ii) or downwardly and inwardly, toward the active portion of the electrolyte sheet surface where one or more device electrodes are deposited. By angling the seal portion of the electrolyte sheet, the sharpness of any resulting bends or deformations that may occur during use can be reduced, thus reducing the likelihood of any cracks forming in the typically high stress regions of the electrolyte sheet. Further, preferably at least a portion of the electrolyte sheet contacting the seal composition, the seal-electrolyte interface may deviate from planarity by at least 0.Type: ApplicationFiled: January 27, 2009Publication date: November 25, 2010Inventors: Thomas Dale Ketcham, John Stephen Rosettie, Dell Joseph St. Julien, Sujanto Widjaja

Patent number: 7803494Abstract: 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.Type: GrantFiled: September 23, 2005Date of Patent: September 28, 2010Assignee: Corning IncorporatedInventors: Michael Edward Badding, Jeffrey Earl Cortright, John David Helfinstine, Thomas Dale Ketcham, Scott Christopher Pollard, Irene M.

Patent number: 7786559Abstract: Methods and assemblies relate to bezel packaging of a sealed glass assembly, such as a frit-sealed OLED device. The bezel packaging includes a shock absorbent intermediate layer of low modulus of elasticity material applied between the sealed glass assembly and the bezel. A bonding agent, which may include the low modulus of elasticity material and/or a separate bonding material, affixes the sealed glass assembly to the bezel. Bezel modifications may be made to stabilize the bezel. Exemplary bezel modifications include reinforced bezel side walls and supporting straps attached between bezel walls. The bezel design may include a gap between the edges of the sealed glass assembly and the bezel walls, so as to avoid direct contact therewith. The gap may be filled at least in part with low modulus of elasticity organic adhesive to provide additional shock absorbency. The low modulus of elasticity material may include foam, ceramic fiber cloth and/or a low modulus of elasticity polymeric organic coating.Type: GrantFiled: November 8, 2006Date of Patent: August 31, 2010Assignee: Corning IncorporatedInventors: John F Bayne, Jamie T Westbrook, Sujanto Widjaja
