Abstract
A pressure-liquefiable gas or vapor fed into the interior of a container which may constitute the fuel tank of a power unit for a model aircraft or other working model, is condensed within the container by introducing either a liquid derived from said gas or vapor or a liquid refrigerant from an external source into the interior of a hollow condensing element mounted in the container with its outer surface in contact with said gas or vapor inside the container, and then exhausting the contents of the condensing element to cool the outer surface thereof to a temperature below the condensation temperature of said gas or vapor.
Claims20
A method of condensing a pressure-liquefiable gas or vapour, said method comprising the steps of:
- feeding said gas or vapour into the interior of a closed container;
- introducing a liquid derived from said gas or vapour into the interior of a hollow condensing element mounted in said container with its outer surface in contact with the gas or vapor inside the container;
- and
- exhausting the contents of said condensing element to cool the outer surface thereof to a temperature below the condensation temperature of said gas or vapour.
Apparatus for promoting the condensation of a pressure-liquefiable gas or vapour, said apparatus comprising:
- a closed container having an inlet for said gas or vapour;
- a condensing element mounted within said container and comprising a hollow receptacle the exterior of which is exposed to the contents of the container and the interior of which communicates with the interior of said container;
- and
- means for exhausting the contents of said receptacle in order to cool the outer surface of said condensing element to a temperature below the condensation temperature of said gas or vapour.
A method of condensing a pressure-liquefiable gas within a closed container comprising the steps of:
- feeding a first quantity of a pressurized gas into the interior of a hollow condensing element disposed within the closed container;
- exhausting the pressurized gas from the interior of the hollow condensing element to cool an outer surface thereof to a temperature below the condensation temperature of the gas;
- and
- introducing a second quantity of the pressurized gas into the interior of the closed container in contact with the outer surface of the hollow condensing element for cooling thereof to a temperature below its condensation temperature.
Apparatus for promoting the condensation of a pressure-liquefiable gas comprising:
- a closed container;
- an condensing element disposed within said container and having a hollow interior and an exterior surface exposed to the contents of the container, the interior of said condensing element being in gaseous communication with the interior of said container;
- inlet means for introducing gas under pressure into the interior of said inner condensing element and into the interior of said container in contact with the exterior surface of said condensing element;
- and
- means for selectively recovering the gas from the interior of said container for use outside of said container and for exhausting the gas from the interior of said condensing element to cool said exterior surface of said condensing element to a temperature below the condensation temperature of the gas, said selective recovering and exhausting means comprising helical path means for removing liquid from the gas.
