Abstract: An apparatus useful for the production of wide amorphous or polycrystalline metal foils of substantially uniform thickness by the double roller chill quenching method comprises a fixed roller member and a spring-loaded movable roller member mounted on a set of mounting rails. The movable roller member is maintained at a selectably adjustable minimum spacing from the fixed roller member and is free to move away from this position of minimum spacing to accommodate forces tending to displace the rollers from one another. A spring urges the movable roller toward the fixed roller and provides for selectable adjustment of the restoring force urging the rollers together.

Abstract: In a process for preparing aperture mask assemblies for color cathode ray tubes, an improvement provides thicker, more adherent protective oxide coatings on the bimetallic mounting members of such assemblies by employing the step of mechanically roughening the surface of the mounting members prior to oxidation.

Abstract: This invention sets forth an improved method of continuously casting a metal filament or fiber from molten liquid metal. The filament is formed by forcing the molten metal from a melt pot through an orifice and solidifying the molten metal jet into a filament while it is moving in a cooling atmosphere. As the solid filament moves with respect to the gas atmosphere, the gas by friction with the surface of the filament will exert a force on the filament, either acceleration or deceleration depending on whether the gas is flowing with a velocity greater or less than the filament velocity. The invention sets forth parameters defining the relations that must exist between the filament velocity and cooling gas velocity which give rise to acceleration and deceleration forces and whose magnitudes determine the formation of continuous filament or fibers.
