Abstract: By maintaining the desired temperature gradient in the molten solvent as the crystal grows and by replenishing the solvent lost by segregation into the growing crystal, a continuous filament crystal is formed. As the crystal is formed it is pulled from the formation area at its speed of growth. A vaporous compound containing the solvent element furnishes a vapor containing the solvent. The solvent vapor condenses on the molten solvent to replenish the solvent lost by segregation into the growing crystal.

Abstract: A night vision device in which a screen has a layer of cholesteric material that is heated to the critical value for maximum extinction of a source of circularly polarized monochromatic light. The screen is irradiated with a source of circularly polarized monochromatic light that is attenuated by said cholesteric material until infrared rays from an object are focused onto the screen to cause localized heating of the cholesteric material and thereby passage of the circularly polarized monochromatic light to an opposite face of the screen. The monochromatic light passing to the opposite face of the screen is viewed as an image of the object.
