Patent number: 7418308Abstract: A method of determining parameters of plurality of thermal cycles to achieve a set glass strain level includes providing a plurality of input parameters for a glass substrate and a plurality of parameters for a plurality of thermal cycles. The method also includes iteratively modifying at least one of the pluralities of thermal cycle parameters so the glass strain is not greater than the set glass strain level after a final thermal cycle is completed. An aspect of the method usefully enables a user to determine from the material parameters and processing sequences of the glass manufacturer and further entities that may further process the glass (e.g., the glass manufacturer's customers) whether a particular glass strain can be achieved; and if not the example embodiments allows the manufacturer to calculate changes in the customers' processes to meet the desired glass strain.Type: GrantFiled: October 31, 2003Date of Patent: August 26, 2008Assignee: Corning IncorporatedInventors: Douglas C. Allan, Motoya Anma, Josef C. Lapp

Patent number: 6197429Abstract: A glass-ceramic material which exhibits extremely low (e.g. less than 100 ppm) shrinkage, when exposed to 900° C. for 6 hours, and methods for making such glass-ceramics. The glass-ceramic is cerammed at a sufficiently high temperature and then cooling in a controlled manner, preferably to below the strain point of the resultant material. Using this technique, glass-ceramic materials were fabricated which exhibited dimensional shrinkage comparable to and in some cases even less than that achieved by fused silica substrates, when exposed to high temperature poly-Si processing temperatures (e.g. 900° C. for 6 hours).Type: GrantFiled: February 26, 1998Date of Patent: March 6, 2001Assignee: Corning IncorporatedInventors: Josef C. Lapp, Chad B. Moore, Linda R. Pinckney

Patent number: 5625427Abstract: An ophthalmic lens of photochromic glass having an R.sub.2 O-Al.sub.2 O.sub.3 -B.sub.2 O.sub.3 -SiO.sub.2 base glass composition and a method of producing the lens. The lens contains precipitated cuprous halide crystals that are elongated and oriented, whereby the lens is capable of polarizing light when the lens is in the darkened state. If at least a portion of the crystals in at least a surface layer on the lens are reduced to copper metal, the lens exhibits a permanent dichroic behavior. The lens provides effective polarization of radiation across the entire visible wavelength region of the spectrum, has a sharp spectral cutoff for radiation below the 400 nm wavelength, thereby eliminating UV transmission, and has a transmittance not over about 40% in the darkened state.Type: GrantFiled: August 23, 1994Date of Patent: April 29, 1997Assignee: Corning IncorporatedInventors: Roger J. Araujo, Nicholas F. Borrelli, Josef C. Lapp, David W. Morgan
