Abstract: A multi component propulsion system utilizing metallic fuel particles and a carrier gas as a propellant medium. The metallic particles and some of the carrier gas are carried from a fluidization chamber to the combustion chamber to be combusted with a liquid oxidizer. A major portion of the carrier gas is passed from the fluidization chamber to the combustion chamber to mix with the products of combustion of the oxidizer and metallic particles.

Abstract: An apparatus for dispensing carbonated fluids or beverages which employs the vapor pressure of the beverage, i.e., the pressure of carbonation, as the sole propelling or dispensing force, is disclosed. The apparatus comprises a valve mechanism that includes a main valve body and an adapter for detachably coupling the valve mechanism to the fluid container or bottle. An elongated siphoning tube projects into the fluid container and in self-sealing engagement with the adapter means. The valve mechanism further comprises a valve stem movably mounted within a central cavity or channel formed in the main valve body, a fluid discharge spout in operable communication with the cavity or channel and a spring which serves to maintain the valve in a normal closed position. The fluid is discharged from the container by causing the valve stem to be moved into a downward and open position.
