  • Patent number: 7101810
    Abstract: 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.

  • Patent number: 6142642
    Abstract: A heat formable mirror is formed by sputter depositing upon a sheet such as glass a reflective coating utilizing a base layer of silicon or a combination of silicon and stainless steel films, a reflective layer formed of a reflective metallic film such as titanium or aluminum, and a protective layer comprising preferably silicon nitride. The resulting mirror can be heat formed at elevated temperatures to form a curved mirror having a reflective coating free of objectionable defects.

  • Patent number: 6086210
    Abstract: A heat formable mirror is formed by sputter depositing upon a sheet such as glass a reflective coating utilizing a base layer of silicon or a combination of silicon and stainless steel films, a reflective layer formed of a reflective metallic film such as niobium, titanium or aluminum, and a protective layer comprising preferably silicon nitride. The resulting mirror can be heat formed at elevated temperatures to form a curved mirror having a reflective coating free of objectionable defects.

  • Patent number: 4999340
    Abstract: 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.
