Transfer of the working medium in the working medium exchange between a closed-cyclegas turbine plant and a reservoir

Claim 1

THE METHOD OF CONTROLLING THE POWER OUTPUT OF A CLOSED CIRCUIT GAS TURBINE POWER PLANT BY VARYING THE WEIGHT OF GASEOUS WORKING MEDIUM THEREIN BY THE TRANSFER OF SAID MEDIUM BETWEEN A STORAGE RESERVOIR, OUTSIDE THE CIRCUIT AND IN WHICH THE PRESSURE MAY BE HIGHER THAN THE MAXIMUM PRESSURE IN THE CIRCUIT OR LESS THAN THE MINIMUM PRESSURE IN THE CIRCUIT, AND EITHER OF TWO POINTS WITHIN THE CIRCUIT, SAID POINTS BEING AT DIFFERENT PRESSURES, WHICH METHOD CONSISTS IN ESTABLISHING A TRANSFER CYCLE THROUGH A FLOW PATH, THE MEDIUM AT HIGHEST PRESSURE BEING CONNECTED WITH SAID PATH AT ONE END THEREOF THROUGHOUT SUBSTANTIALLY ALL OF AN INTERVAL EQUAL TO ONE HALF OF SAID CYCLE, THE MEDIUM AT LOWEST PRESSURE BEING CONNECTED WITH SAID PATH AT SAID ONE END THROUGH SUBSTANTIALLY ALL OF AN INTERVAL OCCURRING DURING AND EQUAL TO THE OTHER HALF OF SAID CYCLE, AND THE MEDIUM AT INTERMEDIATE PRESSURE BEING CONNECTED WITH THE OTHER END OF SAID FLOW PATH THROUGHOUT AN INTERVAL SUBSTANTIALLY EQUAL TO ONE HALF OF SAID CYCLE, SAID LAST MENTIONED INTERVAL BEING 90* OUT OF PHASE WITH SAID OTHER INTERVALS, SAID OTHER END OF THE FLOW PATH BEING CLOSED EXCEPT WHEN SO CONNECTED, THE LENGTH OF SAID FLOW PATH BEING EQUAL TO THE DISTANCE TRAVELLED BY A SOUND WAVE DURING ONE QUARTER OF SAID CYCLE.

Claim 2

THE METHOD OF CONTROLLING THE POWER OUTPUT OF A CLOSED CIRCUIT GAS TURBINE POWER PLANT BY VARYING THE WEIGHT OF GASEOUS WORKING MEDIUM THEREIN BY THE TRANSFER OF SAID MEDIUM BETWEEN A STORAGE RESERVOIR, OUTSIDE THE CIRCUIT AND IN WHICH THE PRESSURE MAY BE HIGHER THAN THE MAXIMUM PRESSURE IN THE CIRCUIT OR LESS THAN THE MINIMUM PRESSURE IN THE CIRCUIT, AND EITHER OF TWO POINTS WITHIN THE CIRCUIT, SAID POINTS BEING AT DIFFERENT PRESSURES, WHICH METHOD CONSISTS IN ESTABLISHING A TRANSFER CYCLE THROUGH A FLOW PATH, THE MEDIUM AT HIGHEST PRESSURE BEING CONNECTED WITH SAID PATH AT ONE END THEREOF THROUGHOUT SUBSTANTIALLY ALL OF AN INTERVAL EQUAL TO ONE HALF OF SAID CYCLE, THE MEDIUM AT LOWEST PRESSURE BEING CONNECTED WITH SAID PATH AT SAID ONE END THROUGH SUBSTANTIALLY ALL OF AN INTERVAL OCCURRING DURING AND EQUAL TO THE OTHER HALF OF SAID CYCLE, AND THE MEDIUM AT INTERMEDIATE PRESSURE BEING CONNECTED WITH THE OTHER END OF SAID FLOW PATH THROUGHOUT AN INTERVAL SUBSTANTIALLY EQUAL TO ONE HALF OF SAID CYCLE, SAID LAST MENTIONED INTERVAL BEING 90* OUT OF PHASE WITH SAID OTHER INTERVALS, SAID OTHER END OF THE FLOW PATH BEING CLOSED EXCEPT WHEN SO CONNECTED, THE LENGTH OF SAID FLOW PATH BEING EQUAL TO THE DISTANCE TRAVELLED BY A SOUND WAVE DURING ONE QUARTER OF SAID CYCLE.
