Patent number: 10029936Abstract: An apparatus for downwardly drawing glass ribbon comprises edge directors, wherein an outer portion defining a first pair of surfaces and a second pair of surfaces. In one example, the first and second pair of surfaces of each edge director includes a glass wettability with a static contact angle within a range of from about 30° to about 60°. In another example, the outer portion comprises a platinum alloy including from about 0.05 weight % tin to about 5 weight % tin. Methods for forming glass include the step of providing the edge director with a desired glass wettability and/or a desired platinum alloy.Type: GrantFiled: June 20, 2014Date of Patent: July 24, 2018Assignee: Corning IncorporatedInventors: Paul Richard Grzesik, Ahdi El Kahlout, Nicolas LeBlond, Gaozhu Peng, Kim E Womer

Patent number: 7828480Abstract: Disclosed is a thermocouple circuit that exhibits reduced levels of thermocouple drift. The thermocouple is generally comprised of first and second thermoelectric elements formed of first and second thermoelectric materials, respectively. The first and second thermoelectric elements are coupled to an electrically conductive substrate through intermediate first and second tab elements, respectively. The first and second tab elements are preferably formed of the respective first and second thermoelectric materials, and coupled to the substrate in a spaced apart configuration such that the first and second tab elements, are not physically coupled one to the other. Also disclosed are systems and methods for the preparation and use of the thermocouple circuits disclosed herein.Type: GrantFiled: December 20, 2007Date of Patent: November 9, 2010Assignee: Corning IncorporatedInventors: Lee Martin Adelsberg, John Michael Drosdak, Paul Richard Grzesik, Trudy A Knutson, David Myron Lineman, Kevin Barry Reiman
