    摘要： A plurality of receiving stations is automatically and pneumatically charged by a pulverized or granular material fed at a relatively low rate through a main conveying pipe into a plurality of series connected intermediate containers. Each intermediate container is connected with a substantially horizontally directed branch conduit which is provided with downwardly directed discharge or sink pipes opening into a preliminary storage hopper of a corresponding receiving station. Each branch conduit is connected via unidirectional valves or via throttles with an auxiliary pneumatic line which when the end of the sink pipe is open, fluidizes the material in the branch conduit and simultaneously discharges it into the preliminary hopper. As soon as the level of charge in the hopper reaches the open end of the sink pipe, the fluidization is interrupted and the loose material from the intermediate container plugs the branch conduit. Only after the level of discharge in the hopper drops below the open ends of the sink pipes, the fluidization and discharge is restarted.

    摘要： A process and apparatus for the production of exposed printing plates consisting of a resin layer and a support, said resin layer being prepared from a fluid photopolymerizable material which is introduced into a mold having at least one transparent wall which is covered with an image-bearing transparency, and being exposed through said image-bearing transparency, which causes photopolymerization of the exposed areas of the resin layer and bonds these areas to the support which is provided with an adhesive layer. The improved process comprises introducing a predetermined amount of fluid photopolymerizable material, said amount corresponding substantially to the volume of the resin layer of the exposed printing plate; adjusting said support and said transparent wall of the mold so that they are equidistant from one another, adjustment being advantageously effected by bending or doming the support relative to the transparent wall after the latter has been bent or domed by the fluid material introduced into the mold under pressure. Further embodiments of the invention serve to minimize the loss of photopolymerizable material and to avoid the formation of foam when the fluid material is introduced into the mold. The apparatus of the invention can be manufactured and operated easily and economically.
