  • Patent number: 11754764
    Abstract: A low infrared absorbing lithium glass includes FeO in the range of 0.0005-0.015 wt %, more preferably 0.001-0.010 wt %, and a redox ratio in the range of 0.005-0.15, more preferably in the range of 0.005-010. The glass can be chemically tempered and used to provide a ballistic viewing cover for night vision goggles or scope. A method is provided to change a glass making process from making a high infrared absorbing lithium glass having FeO in the range of 0.02 to 0.04 wt % and a redox ratio in the range of 0.2 to 0.4 to the low infrared absorbing lithium glass by adding additional oxidizers to the batch materials. A second method is provided to change a glass making process from making a low infrared absorbing lithium glass to the high infrared absorbing lithium glass by adding additional reducers to the batch material. In one embodiment of the invention the oxidizer is CeO2. An embodiment of the invention covers a glass made according to the method.

  • Publication number: 20230173523
    Abstract: A mask and air pressure control system for use in coating deposition is disclosed. A method is provided for controlling liquid coating droplets during deposition onto a substrate by directing atomized liquid coating droplets in a flow path toward the substrate, and applying a vacuum or pressurized air from an air pressure control system to at least a portion of the atomized liquid coating droplets in the flow path. The air pressure control mask comprises an air pressure control fixture structured and arranged for connection to a source of vacuum or pressurized air, and a nozzle opening structured and arranged to at least partially surround a flow path of the liquid coating droplets and to selectively allow at least a portion of the liquid coating droplets to pass through the air pressure control mask, wherein the vacuum or pressurized air prevents at least a portion of oversprayed liquid coating droplets from being deposited on the substrate outside an intended edge of the coating.
