  • SYSTEM AND METHOD FOR DELIVERY OF MEDICATION VIA INHALATION
    Publication number: 20080078385
    Abstract: A Heliox based drug delivery system and method is disclosed. The disclosed system and method involves nebulizing the medication with a helium containing gas stream to form an aerosol stream, delivering the aerosol stream to the patient for inhalation during an aerosol phase, intermittently delivering an oxygen containing gas stream without medication to the patient for inhalation during an aerosol-free phase, and cycling between the aerosol phase and the aerosol-free phase to deliver medication to the patient while maintaining patient oxygenation in a prescribed range. The disclosed systems and methods farther include various positive pressure support techniques as well as thermal management of the aerosol phase and aerosol-free phase.

  • Multicomponent refrigerant fluids for low and cryogenic temperatures
    Patent number: 6881354
    Abstract: Multicomponent refrigerant fluids for generating refrigeration, especially over a wide temperature range including cryogenic temperatures, which are advantageous over conventional refrigerant fluids especially for certain applications, and which are non-toxic, non-flammable and low or non-ozone-depleting and preferably are maintained in variable load form through compression, cooling, expansion and warming steps in a refrigeration cycle.

  • Gas liquefaction method using natural gas and mixed gas refrigeration
    Publication number: 20040148962
    Abstract: A gas liquefaction method which uses the pressure energy of a natural gas processing system to generate refrigeration for high temperature cooling of a gas, and uses a mixed gas refrigerant fluid to generate refrigeration for low temperature cooling of the gas to produce liquefied product.
