Abstract
Abstract The production of power by the utilization of a supply of a gaseous working fluid under pressure to drive a turbine, wherein a substantially unlimited supply of working fluid is provided by the controlled evaporation of a reservoir of the working fluid in a liquefied state in accordance with pressure variations at an appropriate point in the system. Heating of the gaseous working fluid to a preselected temperature and pressure prior to utilization is advantageous.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
A system for producing power comprising a. a turbine having a fluid outlet; b. a plenum chamber filled with a working fluid in its natural gaseous state at a pressure greater than the pressure at said turbine outlet; c. first fluid conduit means operatively connecting said plenum chamber and said turbine, said conduit means including flowregulating means responsive to external control for regulating the mass rate of flow of working fluid to said turbine; d. an insulated fluid vessel containing a reservoir of said working fluid in a liquefied state, said vessel having internal heater means for heating said liquefied working fluid; e. heater control means including pressure-sensing means for sensing fluid pressure conditions at a suitable point in the system and automatically selectively energizing and deenergizing said heater means in accordance with said conditions; and f. second fluid conduit means operatively connecting said fluid vessel and said plenum chamber such that reductions in fluid pressure within said plenum chamber result in the energization of heater means, the gasification of liquefied working fluid within said insulated vessel, and the movement of said gasefied working fluid towards said plenum chamber.
Claim 2
Independent Claim
189 words
A system for producing power comprising a. a turbine having a fluid outlet; b. a plenum chamber filled with a working fluid in its natural gaseous state at a pressure greater than the pressure at said turbine outlet; c. first fluid conduit means operatively connecting said plenum chamber and said turbine, said conduit means including flowregulating means responsive to external control for regulating the mass rate of flow of working fluid to said turbine; d. an insulated fluid vessel containing a reservoir of said working fluid in a liquefied state, said vessel having internal heater means for heating said liquefied working fluid; e. heater control means including pressure-sensing means for sensing fluid pressure conditions at a suitable point in the system and automatically selectively energizing and deenergizing said heater means in accordance with said conditions; and f. second fluid conduit means operatively connecting said fluid vessel and said plenum chamber such that reductions in fluid pressure within said plenum chamber result in the energization of heater means, the gasification of liquefied working fluid within said insulated vessel, and the movement of said gasefied working fluid towards said plenum chamber.
Claim 3
Dependent Claim
40 words
A system in accordance with claim 1 further comprising heat exchanger means operatively coupled into said second fluid conduit means for raising the temperature of said gasified working fluid as it moves from said insulated vessel to said plenum chamber.
Claim 4
Dependent Claim
34 words
A system in accordance with claim 2, said second fluid conduit means comprising check valve means intermediate said insulated vessel and said heat exchanger means operative to prevent fluid movement towards said insulated vessel.
Claim 5
Dependent Claim
34 words
A system in accordance with claim 3, said pressure-sensing means of said heater control means being operatively positioned in said system to detect pressure variations on the upstream side of said check valve means.
Claim 6
Dependent Claim
44 words
A system in accordance witH claim 4, further comprising control means for monitoring said working fluid as it departs said exchanger means and regulating the rate of heat transfer to said working fluid to obtain the desired temperature and pressure conditions for said fluid.
