A catalyst for oxidizing aqueous organic contaminants includes about 5 wt % to about 20 wt % noble metal crystallites selected from the group consisting of platinum, palladium, ruthenium, iridium, and combinations thereof deposited on a high surface area catalyst support. The crystallites are about 100 .ANG. or smaller. A system for catalytically oxidizing aqueous organic contaminants has a catalyst bed containing such a catalyst, means for heating a reactor feed stream to a desired reaction temperature, means oxygenating the feed stream, and a phase separator for separating gaseous reaction products from a reactor effluent stream.

The present invention provides water-soluble, extended-release chemical formulations, in tablet form, for urine pretreatment, that require minimal, if any, use of a binder component, yet are non-dusting, pliable, structurally strong, and not weakened by exposure to aqueous streams. The present invention also provides a simple and reliable method for controlled dispensing of such tableted formulations into a liquid stream that is particularly advantageous for use in micro-gravity environments, such as spacecraft urinal systems.

A membrane humidifying device is disclosed that can operate with normal potable quality water without a demineralizer and which prevents the transport of microbes, particulates, dissolved salts and liquid water to the airstream. It is positioned in the flow path of air to be humidified and comprises at least one membrane cell and a means for introducing water into each cell. The membrane cell is comprised of at least one sheet of a hydrophilic membrane and at least one screen. Ambient or low pressure water is introduced into the membrane cell(s); at least a portion of which contacts or passes through the screen(s); contacts the hydrophilic membrane(s); and is osmotically transported across the membrane(s) where it evaporates into the airstream.

A method and apparatus are disclosed for separating potentially combustible and/or explosive gaseous mixtures from aqueous solutions. The method employs the concept of utilizing a liquid phase carryover as a combustible gaseous diluent and subsequently, upon separation of the gaseous and liquid phase components, incorporates the addition of a diluent gas to minimize the combustive/explosive potential of the separated gaseous phase component. In a preferred embodiment, the separating apparatus comprises a primary separator, a screen atomizer, a pressure-and-flow control system and a secondary separator.

A backpack shelter apparatus which incorporates a backpack, frame means, shelter and shelter support means adjustably coupled to the frame means. The shelter support means can be extended from the frame means to provide support for the shelter, backpack, and frame means. The shelter unfolds from the frame means and is erected to provide an enclosure wherein the backpack is in an upright position and a person can be protected from the elements.
