Vapor deposition device

Claim 1

AN APPARATUS FOR DEPOSITING METAL ON AN ELONGATED SHEET MATERIAL, SAID APPARATUS COMPRISING A HOUSING INCLUDING AN INNER CYLINDRICAL DRUM AND AN OUTER CYLINDRICAL CASING, THE INNER SURFACE OF SAID CASING THE OUTER SURFACE OF SAID DRUM BEING SPACED APART A DISTANCE WITHIN THE RANGE FROM 1/32 TO 1/4 INCH AND DEFINING AN ANNULAR PASSAGE, SAID CASING HAVING AN OPENING AT A FIRST POSITION OF SAID PASSAGE FOR PERMITTING SAID ELONGATED SHEET MATERIAL TO ENTER SAID PASSAGE AT A FIRST EXTREMITY THEEOF AND TO LEAVE SAID PASSAGE AT A SECOND EXTREMITY THEREOF, SAID FIRST EXTREMITY AND SAID SECOND EXTREMITY BEING ADJACENT TO EACH OTHER, SAID CASING HAVING AN OPENING AT A SECOND POSITION OF SAID PASSAGE, A FIRST AUXILIARY CASING COMMUNICATING WITH SAID OPENING AT SAID SECOND POSITION, A ROTATABLE CAGE WITHIN SAID FIRST AUXILIARY CASING, A CONDUIT FOR INTRODUCING AN AUXILIARY GAS INTO SAID FIRST AUXILIARY CASING FOR FLOWING SAID AUXILIARY GAS THROUGH SAID CAGE AND ACQUIRING A HEAT DECOMPOSABLE METAL BEARING VAPOR FROM GRANULAR MATRIAL IN SAID CAGE, A SECOND AUXILIARY CASING COMMUNICATING WITH SAID OPENING AT SAID FIRST POSITION FOR EXHAUSTING SAID PASSAGE, FIRST HEATING MEANS FOR HEATING THE INNER SURFACE OF SAID CASING AT SAID FIRST EXTREMITY OF SAID PASSAGE, SECOND MEANS FOR HEATING THE OUTER SURFACE OF SAID DRUM AT SAID FIRST POSITION, AND CONDUITS FOR INTRODUCING AUXILIARY GAS THROUGH SAID CASING BETWEEN SAID ENTRANCE AND SAID FIRST POSITION AND BETWEEN SAID EXIT AND SAID SECOND POSITION, SAID ANNULAR PASSAGE IN PROFILE EXTENDING THROUGHOUT ALMOST THE WHOLE EXTENT OF A CLOSED CURVE.

Claim 2

AN APPARATUS FOR DEPOSITING METAL ON AN ELONGATED SHEET MATERIAL, SAID APPARATUS COMPRISING A HOUSING INCLUDING AN INNER CYLINDRICAL DRUM AND AN OUTER CYLINDRICAL CASING, THE INNER SURFACE OF SAID CASING THE OUTER SURFACE OF SAID DRUM BEING SPACED APART A DISTANCE WITHIN THE RANGE FROM 1/32 TO 1/4 INCH AND DEFINING AN ANNULAR PASSAGE, SAID CASING HAVING AN OPENING AT A FIRST POSITION OF SAID PASSAGE FOR PERMITTING SAID ELONGATED SHEET MATERIAL TO ENTER SAID PASSAGE AT A FIRST EXTREMITY THEEOF AND TO LEAVE SAID PASSAGE AT A SECOND EXTREMITY THEREOF, SAID FIRST EXTREMITY AND SAID SECOND EXTREMITY BEING ADJACENT TO EACH OTHER, SAID CASING HAVING AN OPENING AT A SECOND POSITION OF SAID PASSAGE, A FIRST AUXILIARY CASING COMMUNICATING WITH SAID OPENING AT SAID SECOND POSITION, A ROTATABLE CAGE WITHIN SAID FIRST AUXILIARY CASING, A CONDUIT FOR INTRODUCING AN AUXILIARY GAS INTO SAID FIRST AUXILIARY CASING FOR FLOWING SAID AUXILIARY GAS THROUGH SAID CAGE AND ACQUIRING A HEAT DECOMPOSABLE METAL BEARING VAPOR FROM GRANULAR MATRIAL IN SAID CAGE, A SECOND AUXILIARY CASING COMMUNICATING WITH SAID OPENING AT SAID FIRST POSITION FOR EXHAUSTING SAID PASSAGE, FIRST HEATING MEANS FOR HEATING THE INNER SURFACE OF SAID CASING AT SAID FIRST EXTREMITY OF SAID PASSAGE, SECOND MEANS FOR HEATING THE OUTER SURFACE OF SAID DRUM AT SAID FIRST POSITION, AND CONDUITS FOR INTRODUCING AUXILIARY GAS THROUGH SAID CASING BETWEEN SAID ENTRANCE AND SAID FIRST POSITION AND BETWEEN SAID EXIT AND SAID SECOND POSITION, SAID ANNULAR PASSAGE IN PROFILE EXTENDING THROUGHOUT ALMOST THE WHOLE EXTENT OF A CLOSED CURVE.
