Claim 1
Independent Claim
129 words
IN A MAGNETOHYDRODYNAMIC DEVICE IONIZING A GAS BY MEANS OF AN IONIZING WAVE, THE COMBINATION COMPRISING A CYLINDRICAL SHELL FORMING A VACUUM CHAMBER, MEANS PRODUCING A LONGITUDINALLY DIRECTED MAGNETIC FIELD IN SAID CHAMBER WHICH FIELD HAS INCREASED INTENSITY AT EACH END OF A PLASMA REGION WITHIN SAID CHAMBER THEREBY FORMING A MAGNETIC MIRROR FIELD AT EACH END OF SAID REGION, A PAIR OF SPACED COAXIAL ELECTRODES DISPOSED AT ONE END OF SAID REGION WITHIN SAID MIRROR FIELD THEREAT, A HIGH VOLTAGE POWER SUPPLY, A FIRST SWITCH COUPLING SAID POWER SUPPLY TO A FIRST OF SAID ELECTRODES, A SECOND SWITCH CONNECTED TO PROVIDE A SHORT CIRCUIT BETWEEN SAID ELECTRODES, CONTROL MEANS CLOSING SAID SECOND SWITCH AN INTERVAL AFTER SAID FIRST SWITCH CLOSES, AND A GAS SUPPLY COMMUNICATING WITH SAID CHAMBER.
