Patent number: 7101810Abstract: Transparent articles comprising transparent, nonmetallic substrate and a transparent film stack is sputter deposited on the substrate. The film stack is characterized by including at least one infrared reflective metal film, a dielectric film over the metal film, and a protective silicon nitride film of 10 ? to 150 ? in thickness over the said dielectric film. The dielectric film desirably has substantially the same index of refraction as does silicon nitride and is contiguous with the silicon nitride film.Type: GrantFiled: April 7, 2005Date of Patent: September 5, 2006Assignee: Cardinal CG CompanyInventors: Robert Bond, Roger P. Stanek, Wayne L. Hoffman

Patent number: 4999340Abstract: The present invention involves a method for separating biological molecules by subjection of said molecules to a separation system in a gel medium. The method most particularly involves the use of a gel slab suitable for such separations which is readily equilibrated with an appropriate solvent for the chosen separation system. An important aspect of the present invention involves the initial preparation of a gel slab comprising between about 0.5% and about 2.0% agarose and between about 1% and about 3.0% linear water-soluble and substantially nonionic polyacrylamide. A preferred gel slab of the present invention contains between about 1% and 3% agarose and about 3% linear, water-soluble, substantially nonionic polyacrylamide. The gel slabs of the present invention are preferably between about 1 mm and 0.5 mm in thickness.Said aged gel slab is then dried to produce a gel precursor sheet.Type: GrantFiled: August 4, 1988Date of Patent: March 12, 1991Assignee: Board of Regents, The University of Texas SystemInventors: Wayne L.
