Abstract:
A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.
Abstract:
A method for printing ink on a substrate comprising the steps of coating a glass substrate with an adhesion promoter, depositing one or more layers of ink on the coated substrate, and laminating the imaged substrate. The substrate can be a glass substrate, and the adhesion promoter can include a silane material, powder coating, organophosphate primer suspended in isopropanol.
Abstract:
Light-coupling systems and methods that employ light-diffusing optical fiber are disclosed. The systems include a light source and a light-diffusing optical fiber optically coupled thereto. The light-diffusing optical fiber has a core, a cladding and a length. At least a portion of the core comprises randomly arranged voids configured to provide substantially spatially continuous light emission from the core and out of the cladding along at least a portion of the length. A portion of the light-diffusing optical is embedded in an index-matching layer disposed adjacent a lower surface of a transparent sheet. Light emitted by the light-diffusing optical fiber is trapped within the transparent sheet and index-matching layer by total internal reflection and is scattered out of the upper surface of the transparent sheet by at least one scattering feature thereon.
