Abstract: A method for applying a mixed metal oxide catalyst to a metallic substrate for the creation of a robust, high temperature catalyst system for use in decomposing propellants, particularly hydrogen peroxide propellants, for use in propulsion systems. The method begins by forming a prepared substrate material consisting of a metallic inner substrate and a bound layer of a noble metal intermediate. Alternatively, a bound ceramic coating, or frit, may be introduced between the metallic inner substrate and noble metal intermediate when the metallic substrate is oxidation resistant. A high-activity catalyst slurry is applied to the surface of the prepared substrate and dried to remove the organic solvent. The catalyst layer is then heat treated to bind the catalyst layer to the surface. The bound catalyst layer is then activated using an activation treatment and calcinations to form the high-activity catalyst system.

Abstract: Stretchable film laminates including a layer of elastomeric openwork, such as a plurality of elastic strands or an elastomeric mesh structure. The stretchable film laminates may include a film layer bonded to the layer of elastomeric openwork, with the film layer having cross-directional stretch and the laminate having a multi-phase stretchability profile. The stretchable film laminates may be made by extruding a film from a die, stretching the film, forming and stretching a layer of elastomeric openwork, conveying the stretched elastomeric openwork onto the film while the film is stretched, and passing the film and the elastomeric openwork through a nip. The invention also includes a machine capable of producing machine-direction, cross-direction, and biaxial stretch materials. The machine includes at least one extruder, at least one filament die and at least one film die both attached to the extruder(s), and at least one nip downstream of the extruder(s).

Abstract: A hydrogen generation system includes a hydrogen generator reacting a steam/methane mixture. Calcium oxide particles in the hydrogen generator absorb a substantial reacted portion of carbon dioxide from the reacted steam/methane mixture. The hydrogen generator discharges a hydrogen/COx gas volume. A methanation unit subsequently converts substantially all of the COx portion of the hydrogen/COx gas volume to methane gas.

Abstract: A robust, high temperature mixed metal oxide catalyst for propellant composition, including high concentration hydrogen peroxide, and catalytic combustion, including methane air mixtures. The uses include target, space, and on-orbit propulsion systems and low-emission terrestrial power and gas generation. The catalyst system requires no special preheat apparatus or special sequencing to meet start-up requirements, enabling a fast overall response time. Start-up transients of less than 1 second have been demonstrated with catalyst bed and propellant temperatures as low as 50 degrees Fahrenheit. The catalyst system has consistently demonstrated high decomposition effeciency, extremely low decomposition roughness, and long operating life on multiple test particles.

Abstract: A targeted elastic laminate material is provided having at least one low tension zone with first filaments having a first basis weight and at least one high tension zone having second filaments with a second basis weight greater than the first basis weight. The second basis weight is greater due to increased average thickness of the second filaments and/or increased frequency of second filaments relative to the first filaments. Methods and modifications of those methods are provided to produce a targeted elastic laminate material according to the preferred embodiments of this invention.
