High temperature adhesive silicone foam composition, foam generating system and method of generating foam

Patent Mead, Judith W [Peralta, NM]; Montoya, Orelio J [Albuquerque, NM]; Rand, Peter B [Albuquerque, NM]; ...

Access to a space is impeded by generation of a sticky foam from a silicone polymer and a low boiling solvent such as a halogenated hydrocarbon. In a preferred aspect, the formulation is polydimethylsiloxane gel mixed with F502 Freon as a solvent and blowing agent, and pressurized with CO.sub.2 in a vessel to about 250 PSI, whereby when the vessel is opened, a sticky and solvent resistant foam is deployed. The foam is deployable, over a wide range of temperatures, adhering to wet surfaces as well as dry, is stable over long periods of time and does not propagate flamemore » « less

Capacitor with a composite carbon foam electrode

Patent Mayer, Steven T [San Leandro, CA]; Pekala, Richard W [Pleasant Hill, CA]; Kaschmitter, James L [Pleasanton, CA]

Carbon aerogels used as a binder for granularized materials, including other forms of carbon and metal additives, are cast onto carbon or metal fiber substrates to form composite carbon thin film sheets. The thin film sheets are utilized in electrochemical energy storage applications, such as electrochemical double layer capacitors (aerocapacitors), lithium based battery insertion electrodes, fuel cell electrodes, and electrocapacitive deionization electrodes. The composite carbon foam may be formed by prior known processes, but with the solid partides being added during the liquid phase of the process, i.e. prior to gelation. The other forms of carbon may include carbon microspheres,more » « less

Patent Block, Jacob [Rockville, MD]; Krupkin, Natalia Vera [Timonium, MD]; Kuespert, Daniel Reid [Columbia, MD]; ...

A composition for transforming a chrysotile asbestos-containing material into a non-asbestos material is disclosed, wherein the composition comprises water, at least about 30% by weight of an acid component, at least about 0.1% by weight of a source of fluoride ions, and a stable foam forming amount of a foaming agent system having both cationic and non-ionic functionality. A method of transforming the asbestos-containing material into a non-asbestos material using the present composition in the form of a foam also disclosed.
