Atomizing nozzle

Claim 1

AN APPARATUS FOR FORMING METAL POWDER COMPRISING MEANS FORMING A DOWNWARDLY EXTENDING DISCHARGE PASSAGE FOR MOLTEN METAL, SAID MEANS HAVING AN OUTER SURFACE AND AN ANNULAR DOWNWARDLY AND OUTWARDLY INCLINED LOWER END SURFACE COMMUNICATING AT SUBSTANTIALLY THE CENTER OF THE UPPER END THEREOF WITH THE DISCHARGE END OF SAID PASSAGE AND INTERSECTING SAID OUTER SURFACE AT THE LOWER END THEREOF THE FORM AN OUTER EDGE, AND A NOZZLE UNIT FORMED WITH AN ANNULAR DOWNWADLY AND OUTWARDLY INCLINED LOWER END DISPOSED IN CONCENTRIC RELATIONSHIP RELATIVE TO SAID ANNULAR SURFACE, SAID NOZZLE UNIT FORMED WITH AN INTERNAL ANNULAR WALL DEFINING A FIRST ANNULAR CHAMBER DISPOSED IN COMMUNICATION WITH SAID ANNULAR APERTURE AND A SECOND ANNULAR CHAMBER RADIALLY SPACED FROM SAID FIRST ANNULAR CHAMBEAR, A PLURALITY OF PORTS FORMED IN SAID ANNULAR WALL PROVIDING FOR COMMUNICATION BETWEEN SAID FIRST AND SAID SECOND ANNULAR CHAMBERS, AND SUPPLY MEANS FOR INTRODUCTING A PRESSURIZED STREAM OF GAS INTO SAID SECOND ANNULAR CHAMBER IN A DIRECTION SUBSTANTIALLY TANGENTIAL RELATIVE TO SAID ANNULAR WALL IMPARTING CIRCULAR MOVEMENT TO THE STREAM OF GAS IN SAID SECOND CHAMBER AND PASSAGE THEREOF THROUGH SAIDPORTS INTO SAID FIRST ANNULAR CHAMBER AND DISCHARGE THEREFROM THROUGH SAID ANNULAR APERTURE IN THE FORM OF A DOWNWARDLY EXTENDING CONVERGING VORTEX DIRECTED ACROSS SAID OUTER EDGE OF SAID INCLINED SURFACE FOR DRAWING MOLTEN METAL OUT OF THE LOWER END OF SAID DISCHARGE PASSAGE AND ALONG SAID INCLINED SURFACE AND EFFECTING ATOMIZATION AT SAID OUTER EDGE.

Claim 2

AN APPARATUS FOR FORMING METAL POWDER COMPRISING MEANS FORMING A DOWNWARDLY EXTENDING DISCHARGE PASSAGE FOR MOLTEN METAL, SAID MEANS HAVING AN OUTER SURFACE AND AN ANNULAR DOWNWARDLY AND OUTWARDLY INCLINED LOWER END SURFACE COMMUNICATING AT SUBSTANTIALLY THE CENTER OF THE UPPER END THEREOF WITH THE DISCHARGE END OF SAID PASSAGE AND INTERSECTING SAID OUTER SURFACE AT THE LOWER END THEREOF THE FORM AN OUTER EDGE, AND A NOZZLE UNIT FORMED WITH AN ANNULAR DOWNWADLY AND OUTWARDLY INCLINED LOWER END DISPOSED IN CONCENTRIC RELATIONSHIP RELATIVE TO SAID ANNULAR SURFACE, SAID NOZZLE UNIT FORMED WITH AN INTERNAL ANNULAR WALL DEFINING A FIRST ANNULAR CHAMBER DISPOSED IN COMMUNICATION WITH SAID ANNULAR APERTURE AND A SECOND ANNULAR CHAMBER RADIALLY SPACED FROM SAID FIRST ANNULAR CHAMBEAR, A PLURALITY OF PORTS FORMED IN SAID ANNULAR WALL PROVIDING FOR COMMUNICATION BETWEEN SAID FIRST AND SAID SECOND ANNULAR CHAMBERS, AND SUPPLY MEANS FOR INTRODUCTING A PRESSURIZED STREAM OF GAS INTO SAID SECOND ANNULAR CHAMBER IN A DIRECTION SUBSTANTIALLY TANGENTIAL RELATIVE TO SAID ANNULAR WALL IMPARTING CIRCULAR MOVEMENT TO THE STREAM OF GAS IN SAID SECOND CHAMBER AND PASSAGE THEREOF THROUGH SAIDPORTS INTO SAID FIRST ANNULAR CHAMBER AND DISCHARGE THEREFROM THROUGH SAID ANNULAR APERTURE IN THE FORM OF A DOWNWARDLY EXTENDING CONVERGING VORTEX DIRECTED ACROSS SAID OUTER EDGE OF SAID INCLINED SURFACE FOR DRAWING MOLTEN METAL OUT OF THE LOWER END OF SAID DISCHARGE PASSAGE AND ALONG SAID INCLINED SURFACE AND EFFECTING ATOMIZATION AT SAID OUTER EDGE.
