Abstract: A microimpactor device for separating particles from a fluid stream includes a plurality of microimpactor in a two-dimensional array. Individual microimpactors are separated by a distance of about 3 to 20 times the microimpactor width. This spacing provides a device that operates well at low pressure drops across the device. Particles borne in a fluid stream tend to accumulate on both the front and rear sides of the microimpactors, thereby increasing the efficiency of the device.

Abstract: A method and apparatus for purifying air to deactivate toxic chemical and biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, Anthrax spores, E. coli bacteria, Salmonella bacteria, Hepatitis virus, and Norwalk virus. The apparatus comprises a reaction chamber coupled to a counterflow heat exchanger. Incoming contaminated air is directed through a heating side of a counterflow heat exchanger to preheat it. The air is further heated to a temperature of at least 200° C., which is sufficient to deactivate common biological toxic species. Optionally, the reaction chamber may include a catalyst on a surface area over which the heated air is directed, which enables a thermocatalytic reaction that is particularly effective in deactivating biological and chemical warfare agents, such as anthrax and Sarin. Portable embodiments of the invention are useful in both military and civilian air purifying applications, while fixed installation of the apparatus are useful in deactivating toxic species from the air in areas where food is prepared or stored, or in purifying air in the environment of a living space.

Abstract: A hydrothermal conversion process includes a mixing step wherein an aqueous slurry of a solid feedstock material with a steam stream to produce a reaction mixture having a temperature of at least 160° C. and which is at a pressure sufficient to keep water as a subcooled liquid. The process is fast and effective, requires only simple equipment and is highly energy-efficient. The process is also readily scalable, can be operated continuously or semi-continuously and can be tailored to produce carbonized solids or liquefaction products, all of which typically have increased economic value compared with the starting materials.

Abstract: Fluids are atomized using a miniaturized electrostatic microinjector. The microinjectors are capable of producing uniform droplets in several spray modes, and metering and dispersing very small volume fluids. The atomizer is useful in carburetion systems for internal combustion engines, to prepare samples for analytical methods such as MALDI, for fluid filtration and separation, and in other applications.

Abstract: A method and apparatus for purifying water by using thermal and/or thermocatalytic processes. The method and apparatus are particularly useful for processing impure water to remove and/or deactivate toxic inorganic, organic, and/or biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, anthrax, E. coli, Giardia cysts, salmonella, hepatitis, and Norwalk viruses. In the thermal process, contaminated water is heated (preferably superheated) forming steam, whereby a majority of inorganic and biological species are removed or deactivated from the water. The steam is then condensed, forming liquid purified water. In the thermocatalytic process, the steam is brought into contact with a hydrolysis catalyst, preferably in the form of a coated surface or replaceable catalyst element. The hydrolysis catalyst, which may be a metal oxide, thermocatalytically deactivates at least 90% of the organic or biological species in the water, converting them to less toxic organic species or non-viable biological species. Various embodiments of the apparatus are provided, including portable configurations. Each of the embodiments include at least one boiler, at least one condenser, and a water reservoir arranged in heat exchange relationship so as to improve an overall operating efficiency of the apparatus. The apparatus is heated using a portable stove or other heat source, and a counterflow heat exchanger preheats water that is to be vaporized and cools the purified liquid water formed in a condenser.

Abstract: According to the present invention, a method and apparatus rely upon tomographic measurement of the speed of sound and fluid velocity in a pipe. The invention provides a more accurate profile of velocity within flow fields where the speed of sound varies within the cross-section of the pipe. This profile is obtained by reconstruction of the velocity profile from the local speed of sound measurement simultaneously with the flow velocity. The method of the present invention is real-time tomographic ultrasonic Doppler velocimetry utilizing a to plurality of ultrasonic transmission and reflection measurements along two orthogonal sets of parallel acoustic lines-of-sight. The fluid velocity profile and the acoustic velocity profile are determined by iteration between determining a fluid velocity profile and measuring local acoustic velocity until convergence is reached.
