摘要： Refractory metal powders are dehydrided in a device which includes a preheat chamber for retaining the metal powder fully heated in a hot zone to allow diffusion of hydrogen out of the powder. The powder is cooled in a cooling chamber for a residence time sufficiently short to prevent re-absorption of the hydrogen by the powder. The powder is consolidated by impact on a substrate at the exit of the cooling chamber to build a deposit in solid dense form on the substrate.

摘要： A multi-station flexographic printing system includes a plurality of flexographic printing stations. Each flexographic printing station includes a flexo master. Each flexo master comprises a Fresnel zone pattern in a unique position. A method of aligning a plurality of flexographic printing stations includes printing a Fresnel zone pattern on a substrate in a unique position for each flexographic printing station. Light is directed through the Fresnel zone patterns on the substrate. The light focused by the Fresnel zone patterns is captured with a sensor device.

摘要： A method for making a light guide includes transferring ink onto a master tool having a three-dimensional feature pattern formed thereon and then transferring ink from the master tool to a transparent light guide. The method also includes curing the ink on the light guide. Alternatively, the ink may be printed onto a substrate (e.g., a film) and then laminated to the light guide.
