Axial flow turbine with radial temperature gradient

Claim 1

IN AN AXIAL FLOW TURBINE AT LEAST ONE ROTARY BUCKET-WHEEL, THE COMBINATION OF MEANS CREATING A RADIAL TEMPERATURE GRADIENT IN THE FLUID IN SAID FLOW PASSAGE WHEREBY THE TEMPERATURE IS HIGHER TOWARD THE OUTER RADIUS OF SAID FLOW PASSAGE, AND A PLURALITY OF RADIALLY EXTENDING NOZZLE PARTITIONS DISPOSED AT THE END OF SAID FLOW PASSAGE AND IMPARTING VARYING TANGETIAL VELOCITY COMPONENTS TO THE MOTIVE FLUID AT DIFFERENT RADII FROM THE AXIS OF THE BUCKETWHEEL SO THAT THE TANGETIAL MACH NUMBER OF SAID VELOCITY COMPONENT VARIES SUBSTANTIALLY INVERSELY WITH THE RADIUS FROM THE AXIS OF ROTATION, AND A PLURALITY OF RADIALLY EXTENDING, ROTATABLE BLADES DISPOSED BEYOND SAID NOZZLE PARTITIONS AND ATTACHED TO SAID ROTARY-BUCKET WHEEL, THE LEADING EDGES OF SAID BLADES BEING WARPED FROM ROOT TO TIP TOWARD THE PLANE OF ROTATION SO THAT THE ENTRY ANGLES OF SAID BLADES VARY WITH RADIUS TO CONFORM TO THE FLUID LEAVING SAID NOZZLE PARTITIONS WHEN THE BLADES ARE ROTATING.
