Abstract: Life support apparatus composed of: a garment (2): for completely enclosing a wearer and constructed for preventing passage of gas from the environment surrounding the garment (2); a portable receptacle (6) holding a quantity of an oxygen-containing fluid in liquid state, the fluid being in a breathable gaseous; state when at standard temperature and pressure; a fluid flow member (16) secured within the garment (2) and coupled to the receptacle (6) for conducting the fluid in liquid state from the receptacle (6) to the interior of the garment (2); and a fluid flow control device (14) connected for causing fluid to flow from the receptacle (6) to the fluid flow member (16) at a rate determined by the breathable air requirement of the wearer, wherein fluid in liquid state is conducted into the interior of the garment (2) at a rate to be vaporized and heated to a breathable temperature by body heat produced by the wearer.

Abstract: Disclosed is a regasifying pasteurization system and related methods using compressional waves. The system first degasifies the incoming liquid acoustically and under a static pressure below atmospheric pressure. The compressional waves used in degasification are preferably modulated to increase efficiency. The degassed liquid is then exposed to vaporous cavitation in a microorganism disintegrator wherein microorganisms are disintegrated and killed, preferably using frequency modulated compressional waves and vacuum pressures. The regassified pasteurization system also includes a regasification subsystem which injects gases back into the liquid. The gases are sometimes the same gases removed during the degasification step. The degasification and disintegration step form independent subsystems and combine to form a pasteurization subsystem all of which can be used independent of the regasification subsystem.

Abstract: An acoustic resonator apparatus for efficiently transmitting acoustic energy from a plurality of acoustic transducers to a fluid passing through a cylindrical shell. A plurality of pairs of acoustic transducers are mounted on the cylindrical shell, each transducer of a pair being 180.degree. away from the other transducer of the pair, and each pair being associated with another transducer pair which is disposed 90.degree. away from such pair. Each of the transducer pairs is excited with energy of the same frequency and magnitude, but transducer pairs which are disposed 90.degree. from each other are excited with energy which is out of phase by 180.degree..

Abstract: A gas stabilization unit eliminates unwanted gaseous material and adds desired gaseous material from a fluid stream by applying sonic vibrations in two stages to create readily removable bubbles of the gaseous material. A siphon assembly located downstream removes the bubbles.
