Abstract: The disclosure relates to a viewing optic. In one embodiment, the disclosure relates to a viewing optic with an active display and an enabler interface. In one embodiment, the disclosure relates to a system comprising a viewing optic with an active display and an imaging device.

Abstract: The disclosure relates to a viewing optic with an integrated display system. In one embodiment, the viewing optic has an active display system that generates and projects the image into a first focal plane of the optical system. In yet another embodiment, the disclosure relates to a viewing optic with a power pack or battery pack.

Abstract: Deicing chemicals intended primarily for decing pavement such as roads, bridges, and runways are prepared from polysaccharide sources (e.g., waste products such as sawdust) by reaction at a pressure of less than 600 psi and a temperature less than 200.degree. C. with a treating agent comprising alkali metal carbonates or bicarbonates or a mixture thereof and excess oxygen in the presence of water followed by the removal of oxalate and the treating agent. The reaction produces a liquid or a liquid/solid reaction product wherein the liquid contains the deicing chemical and the solid comprises a valuable pulp by-product. Calcium oxide or calcium hydroxide may be added to reduce the pressure resulting from the formation of large amounts of carbon dioxide during the reaction process and to aid in the removal of any oxalic acid formed during the reaction process.

Abstract: De-icing chemicals intended primarily for de-icing pavement such as roads, ridges, and runways are prepared from polysaccharide sources (e.g. waste products such as sawdust) by reaction at elevated pressure and temperature with alkaline earth metal oxides or hydroxides in the presence of water. The de-icing chemicals are impure mixtures of alkaline earth metal salts of acetic acid, lactic acid and glycolic acid with the mixture being substantially free of alkaline earth metal salts of oxalic acid and formic acid. The de-icing chemicals are intended to be a substitute for the inorganic chloride salts (e.g. sodium chloride) commonly used for de-icing highways.
