An air inlet passage (2d) of the air stop valve is arranged at an air column end and is heat sealed.
When the enteral tube and sealed air column are inserted into the stomach and submerged in gastric contents, pressure is exerted against the flexible membrane, and therefore against the sealed air column.
As a result, an air column is formed by introducing burned gas from the nozzle hole, generating microbubbles in the fuel at the interface with the air column.
The air column (30) changes depending on liquid level variations.
The air column is passed through a heating means (40), so as to heat the air, and then the cleaning fluid from supply tank (12) is injected into the air column against the direction of air flow.
The illustrative GMS comprises a plenum, and a first and a second uptake structure.
The adjustable inflatable air cushion (4) of the shoulder strap back cushion (2) is connected with the air bag column (73) through a linking pipe (8).
A first aspect relates to the creation of a column of rising air in a stack to drive electricity-generating turbines.
A fan with a diameter between 15 to 40 feet consisting of a plurality of blades (316), with each in the shape of a tapered airfoil, is driven by an electric motor (304) to produce a very large slowly moving column of air.
An increase of the flux density in the air gap (54) and thus a performance increase of the machine are achieved in this way.
The plenum is fluidically coupled to the first and second uptake structures.
The gas-seal stack (19) prevents substantial portions of the exhaust gas from exiting there through due to formation of a column of higher density ambient air.
