    摘要: A rotating separator removes air coating from pigmented paper coating liquid stock. The separator employs a cylindrical tank which is mounted for rotation about a vertical axis. The separator is operated in a filled condition and an air laden or froth fraction is removed from a radially central region of the tank at the top of the tank, while a non-rotating pickup receives air free coating from a region adjacent the wall of the tank near the tank bottom. A method of treating and applying such a coating includes the steps of pumping an air laden coating into a centrifugal separator while maintaining the separator in a filled condition, removing an air froth from the separator for return to the supply tank, and delivering a substantially air free coating directly to the inlet of a control without the imposition of any intermediate pumping apparatus. The centrifugal pumping action of the separator supplements the pressure head on the coating material.

    摘要: Porous carbon sheets suitable for use as fuel cell electrode support plates are produced by stabilizing acrylic filament precursors through the controlled addition of oxygen thereto. The stabilized filaments are thereafter chopped into short lengths, felted and pressed into sheets with the pressing step being performed at a temperature determined by the oxygen content of the stabilized filaments. The sheets are thereafter pyrolyzed to produce the desired porous substrate material.
