Abstract: An air cooling and water condensate removal panel has at least two interconnected capillary systems close to a plate having cooling means for removing heat from the plate. The first capillary system exists in a porous, thin outer layer having a very fine capillary structure which presents a cool, wettable surface upon which moisture in the air condenses. The outer layer is maintained cool by the cold plate. The condensate water soaks through the thin porous outer layer and is drawn into the interconnected second capillary system. The second capillary system is substantially coarser than the first system to cause the water to be drawn away more rapidly than the condensate can form upon the outer surface. The water in the coarser capillary system is drawn into a discharge pipe, preferably by employing a pump to maintain a mild vacuum in the pipe.

Abstract: A display system employing a panel having a chamber containing an electric field responsive light gating liquid. Means are provided for establishing a pattern of electrical charges corresponding to the information to be displayed. Light gating particles in the liquid respond to the fields of the electrical charge pattern by moving toward alignment with the electric field lines or by otherwise altering their transmission or reflectance of light and by so doing form a visual image.
