Abstract: A system for forming a multi-layer film, where the system includes a backing support having a surface and a close-coupled unit configured to be disposed adjacent the surface of the backing support. The close-coupled unit includes. a corona electrode and a coating die disposed at a downstream location along the surface from the corona electrode.

Abstract: A method and system for forming a multi-layer film, comprising corona treating a surface of a substrate in a processing environment having a positive pressure and an oxygen concentration of about 100 parts-per-million by volume or less, and coating the corona-treated surface of the substrate with a coating material while the substrate is within the processing environment.

Abstract: An aperture mask is provided comprising an elongated web of flexible film having at least one deposition mask pattern formed in the film, wherein the deposition mask pattern defines deposition apertures that extend through the film that define at least a portion of one or more electronic circuit elements, and wherein deposition apertures are bounded by a rim, the rim being a portion of the mask which has a thickness greater than an average thickness for the mask.

Abstract: The present invention provides an apparatus and methods for flame-perforating polymeric films with an oxygen-enriched flame. One embodiment of the apparatus includes a frame, a support surface attached to the frame, where the support surface includes a plurality of lowered portions, an oxygen-enrichment system for increasing the amount of oxygen in the combustible mixture, a burner attached to the frame opposite the support surface, where the burner supports a stable flame, and a film contacting the support surface, where the flame of the burner is directed towards the film to cause the film to be perforated. One embodiment of the method of flame perforating a polymeric film includes igniting an oxygen-enriched combustible mixture to form a stable flame, wherein the flame generated by the oxygen-enriched combustible mixture provides more uniform perforations.

Abstract: A recording assembly having a rack mountable housing is disclosed. The rack mountable housing disclosed has a width dimension sized to fit within a standard opening or spacing between rails of the rack. The recording assembly is mounted to rails on the rack via mounting flanges. The mounting flanges include slots which align with openings on the rails to connect the flanges to the rack. In illustrated embodiments, the mounting flanges are formed integral with the housing or on a separate bracket or shelf unit which is secured to the rack to support or mount the data recording assembly.

Abstract: A norbomene-based cyclic olefin layer with a curable layer disposed thereon is described. The curable layer may additionally be imparted with a texture. The norbomene-based cyclic olefin films with curable layers can be incorporated into optical bodies which include an optical film, such as an oriented multilayer optical film. In addition, the invention includes a method of coating a curable layer onto a norbomene-based polymer layer or film without requiring a primer layer. Methods of making the norbomene-based cyclic olefin layer containing films are also disclosed.

Abstract: Methods and systems utilize an atmospheric-pressure nitrogen dielectric-barrier discharge to treat the surface of polymer substances. The atmospheric-pressure nitrogen dielectric-discharge may be maintained with a level of H2O below a pre-defined amount, such as by measuring and controlling the H2O within a treater, to produce a surface treatment for a polymer substance that yields desirable characteristics. Furthermore, the H2O level may be measured and controlled according to a pre-defined amount or according to another parameter such as an analysis of the resulting polymer surface. For example, the polymer surface may be provided with an optimal added nitrogen-to-added oxygen ratio and/or an optimal stability based on washed and unwashed advancing contact angles such as by controlling the H2O level within the treater based on these analyses of the treated polymer.
