Abstract: Formulations for anti-icing compositions are of two basic types. The first basic formulation describes alcohol/polyol-based aqueous fluids thickened by the combination of an acrylic emulsion and a water-swellable layered clay mineral, with optional addition of a surfactant combination comprised of a first surfactant with an HLB≦3 coupled with a second surfactant with an HLB 19, and further optional addition of a water-activated polymer and other components. The second basic formulation describes a polyol-based aqueous solution of polyvinyl alcohol with optional thickeners.

Abstract: An insulated barrier comprising first and second gas impermeable rigid walls, preferably of a composite of an organic substrate, such as plastic, coated with an inorganic matrix, such as a metal oxide, adjoining surfaces between the first and second walls in order to create an entirely closed and substantially hermetically sealed structure, a core material between the walls comprising an open-cell structure and an optional vacuum breach sensor within the insulated barrier by which the presence of atmospheric oxygen may be detected. Also disclosed is a process by which insulated barriers may be manufactured in accordance with the present invention.

Abstract: Disclosed is a process for the production of organic aerogels, whereby the organic solvent in which the gel is immersed is directly extracted supercritically without the need for exchange with a low temperature solvent (i.e., CO.sub.2) prior to extraction of the pore fluid.
