Abstract: Hydrophobic coating systems, suspensions for forming hydrophobic coatings, and methods for fabricating hydrophobic coatings are provided. In an exemplary embodiment, a hydrophobic coating system comprises a substrate and a hydrophobic coating disposed on the substrate. The hydrophobic coating comprises agglomerates formed of a fluorinated polymer and a plurality of chemically inert particles having an average size of no greater than about 0.1 ?m. The hydrophobic coating exhibits contact angles greater than about 90 degrees.

Abstract: Flexible insulated wires for use in a high temperature environment include a conductor and a coating over the conductor. The coating is formulated from a dielectric material and an organic binder having an organic component, wherein the organic component has been substantially decomposed from the coating during manufacture. The flexible insulated wire may be incorporated into a component.

Abstract: The present invention provides an economical and efficient system for the catalytic conversion of ozone, particularly in airplane bleed air. The present invention comprises a washcoat on a single surface layer, wherein the washcoat may contain an active metal oxide which is active for ozone conversion where the metal oxide comprises a transition metal. Alternatively, the system may comprise a refractory metal oxide washcoat into which a transition metal active for ozone conversion is impregnated.

Abstract: A tube assembly for cooling an incoming fluid stream and destroying pollutants contained therein comprises a tube with a catalytic coating on its inner wall and an arrangement for disrupting laminar flow of the fluid stream as it transits the tube, thereby causing turbulence which increases mass transfer between the gas phase and the catalyst-coated inner surfaces. One embodiment comprises an axially inserted turbulator that is segmented by one or more axially directed cuts, each segment rotated by an offset angle with respect to an adjacent segment, and optionally coated with the catalytic coating. Another embodiment comprises sets of opposed dimples, each set separated from its adjacent set by a linear distance and an axial angle. Such tube assemblies may be advantageously employed in aircraft environmental control systems for conditioning cabin air.

Abstract: The present invention provides a method and system for combined conversion of ozone and organic compounds in airplane bleed air. Catalytic converters have previously been used to reduce the levels of ozone in airplane bleed air. However, these converters have not yet provided an efficient system and method for effectively and simultaneously removing both ozone and organic compounds (including hydrocarbons). The present invention accomplishes the goals of removing both harmful substances by providing a washcoat on a single anodized surface layer, wherein the washcoat may contain an active metal oxide which is active for ozone conversion and may be impregnated with an active metal which is active for hydrocarbon and carbon monoxide conversion. Thus, a single system is disclosed that destroys both ozone and hydrocarbons.
