Magnetohydrodynamic equipment for producing a.c. power

Claim 1

IN COMBINATION WITH A MAGNETOHYDRODYNAMIC GENERATOR HAVING A DUCT FOR CONVEYING A STREAM OF ELECTRICALLY CONDUCTIVE GAS AND HAVING MEANS FOR ESTABLISHING MAGNETIC FLUX THROUGH THE DUCT TRANSVERSE OF THE DIRECTION OF GAS MOVEMENT, A CATHODE AND A PAIR OF OPPOSED ANODES WITHIN THE DUCT WITH THE SEPARATION BETWEEN CATHODE AND ANODES NORMAL TO THE MAGNETIC FLUX AND TO THE DIRECTION OF GAS MOVEMENT, A PAIR OF ROTARY SWITCHES AND MEANS FOR DRIVING AND SWITCHES AT CONSTANT SPEED, EACH SWITCH INCLUDING A CYLINDRICAL ROTOR HAVING OPPOSED INTERCONNECTED ELECTRICALLY CONDUCTIVE SEGMENTS AND A PAIR OF BRUSHES FOR ESTABLISHING ELECTRICALLY CONTACT WITH SAID SEGMENTS DURING ROTATION OF SAID ROTOR, ONE BRUSH ASSOCIATED WITH EACH ROTOR BEING ELECTRICALLY CONNECTED INDIVIDUALLY TO ONE EACH OF SAID ANODES, A TRANSFORMER PRIMARY THE ENDS OF WHICH ARE CONNECTED TO THE REMAINING BRUSHES ASSOCIATED WITH SAID ROTORS, A CONDUCTOR INTERCONNECTING THE MIDPOINT OF SAID TRANSFORMER PRIMARY AND SAID CATHCODE, AND A TRANSFORMER SECONDARY COUPLED TO SAID TRANSFORMER PRIMARY WHEREBY ROTATION OF SAID ROTORS COMPLETES ALTERNATE ELECTRICALLY CONDUCTIVE PATHS THROUGH SAID TRANSFORMER PRIMARY FOR INDUCING AN ALTERNATING CURRENT IN SAID TRANSFORMER SECONDARY.
