Patent number: 8323749Abstract: The invention relates to a process for applying a liquid UV-curable primer sealant to natural stone tiles and related articles followed immediately by the exposure to a requisite amount of low intensity UVA-type UV radiation to partially cure the primer sealant. The partial curing, or pre-setting, of the primer sealant enables control of the ultimate depth of penetration of the primer sealer into the natural stone tiles and natural stone articles of which many examples are quite porous. Because the low level UV irradiation is instantaneous after the primer sealant application the level of primer sealant penetration into the natural stone surface is regulated. The pre-curing of the primer sealant is conducted to intentionally solidify or immobilize the sealant that has actually penetrated into the natural stone surface. The uppermost layers of the primer sealant are left in a semi-liquid or uncured state to allow for wetting and intermingling by the top sealant once it is applied.Type: GrantFiled: January 29, 2009Date of Patent: December 4, 2012Assignee: Questech CorporationInventors: Roger Questel, Larry Wasowski, Dorian C.

Publication number: 20020064713Abstract: A method of forming a strong phase shift mask substrate. A substrate is introduced into a deposition chamber. The substrate has a surface, and is transmissive to electromagnetic radiation of a desired wavelength. A first precursor having at least a first component and a second component is introduced, and covers the surface of the substrate to a thickness of one molecular layer of the first precursor. The excess of the first precursor is removed from within the deposition chamber. A second precursor having at least a third component and a fourth component is introduced. The second precursor attaches to the first precursor. The excess of the second precursor is removed from within the deposition chamber. The first precursor is reacted with the second precursor to form a first monolayer of the first component and the third component on the surface of the substrate. The first monolayer is operable to cause a first phase shift in the electromagnetic radiation of the desire wavelength.Type: ApplicationFiled: November 29, 2000Publication date: May 30, 2002Inventor: Richard D.

Patent number: 6210537Abstract: The present invention provides electronically conducting polymer films formed from photosensitive formulations of pyrrole and an electron acceptor that have been selectively exposed to UV light, laser light, or electron beams. The formulations may include photoinitiators, flexibilizers, solvents and the like. These solutions can be used in applications including printed circuit boards and through-hole plating and enable direct metallization processes on non-conducting substrates. After forming the conductive polymer patterns, a printed wiring board can be formed by sensitizing the polymer with palladium and electrolytically depositing copper.Type: GrantFiled: June 19, 1995Date of Patent: April 3, 2001Assignee: Lynntech, Inc.Inventors: Oliver J.
