Abstract: A chemochromic indicator is provided that includes a hypergolic fuel sensing chemochromic pigment that change from a first color to a second color in the presence of a hypergolic fuel. In a first embodiment, a chemochromic indicator is provided for detecting the presence of a hypergolic fuel such that the irreversible hypergolic fuel sensing chemochromic pigment includes potassium tetrachloroaurate (KAuCl4). There are several types of chemochromic indicators, for example, the article used to form the chemochromic indicators include, but are not limited to, wipe materials, silicone/TEFLON tape, manufactured parts, fabrics, extruded parts, and paints.

Abstract: A portable temperature maintaining apparatus has primary walls having a relatively high thermal resistance and inner and outer surfaces where the inner surfaces define a primary chamber. One of the primary walls serves as a selectively movable lid such that items can be placed in the primary chamber. At least a first secondary wall is formed within the primary chamber and defines at least a portion of a first secondary chamber existing within the primary chamber capable of storing a free-flowing consumable liquid that is poured into the first secondary chamber. The thermal resistance of the at least first secondary wall is selected to be of relatively low thermal resistance or relatively high thermal resistance. A spigot is provided that passes through a primary wall and into communication with the secondary chamber such that any liquid stored in the secondary chamber can be dispensed therefrom.
