Abstract:
An apparatus including: (a) a substrate including a deposition region and an optional uncoated region, wherein the deposition region includes a level intermediate region disposed between a first end region and a second end region, wherein the first end region includes a first raised surface portion extending above the level intermediate region and extending circumferentially around the first end region in a continuous manner; and (b) a dip coated layer over the entire deposition region.
Abstract:
An apparatus, to be used when an open end of a hollow substrate contacts a coating solution to define a solution free interior portion of the substrate, for controlling the level of the coating solution relative to the substrate interior, the apparatus including: a gas container capable of changing in volume; a channel connecting the gas container to the solution free interior portion of the substrate to allow gas flow in either direction between the gas container and the solution free interior portion; and pressure means for exerting a changeable, continuous pressure on the gas container that automatically exerts an increasingly greater pressure on the gas container as the gas container expands in volume and that automatically exerts a decreasingly lesser pressure on the gas container as the gas container decreases in
Abstract:
A coating method for a hollow substrate including: (a) forming a seamed extended substrate unit composed of a substrate extension device and the substrate, and employing a chuck assembly to internally grip the substrate; (b) dip coating the extended substrate unit while the chuck assembly internally grips the substrate to deposit a layer first on the substrate extension device and then on the substrate; and (c) separating, subsequent to the dip coating the extended substrate unit, the substrate extension device from the substrate.
Abstract:
An apparatus comprising: (a) a substrate including a level intermediate region disposed between a first end region and a second end region; (b) a first external member disposed circumferentially around the first end region in a continuous manner and protruding above the level intermediate region, thereby resulting in a deposition region including the surface of the first external member covering the first end region, an optional exposed first end region portion, and the intermediate region; and (c) a dip coated layer over the entire deposition region, wherein the portion of the dip coated layer over the first external member and the optional exposed first end region portion is formed prior to the portion of the dip coated layer over the intermediate layer.
