Apparatus and method for production of carbon black

Claim 1

THE METHOD OF ALLOMERATING CARBON BLACK PARTICLES IN THE EFFLUENT SMOKE FROM CARBON BLACK FURNACES AND SEPARATING SAID CARBON BLACK PARTICLES FROM SUBSTANTIALLY ALL OF THE GASEOUS PORTION OF SAID SMOKE, COMPRISING DIVIDING THE SMOKE INTO TWO STREAMS, PASSING ONE STREAM THROUGH A CONDUIT WHEREIN IN CARBON BLACK PARTICLES IN SAID ONE STREAM COME INTO CONTACT WITH FIRST METALLIC SURFACES HAVING A HIGHER WORK FUNCTION THAN THE CARBON BLACK PARTICLES THEREBY TO IMPART A POSITIVE CHARGE TO THE CARBON BLACK PARTICLES AND A NEGATIVE CHHANGE TO THE METALLIC SURFACE AND CONTINUOUSLY DRAWING OFF THE NEGATIVE CHARGES FROM SAID METALLIC SURFACES SO AS TO AVOID ACCUMULATION OF NEGATIVE SURFACE CHARGES ON SAID FIRST METALLIC SURFACES, THE MAGNITUDE OF THE POSITIVE CHARGE ACQUIRED BY SAID CARBON BLACK PARTICLES IN SAID ONE STREAM BEING DEPENDENT UPON THE RELATIVE WORK FUNCTIONS OF SAID FIRST METALLIC SURFACES AND SAID CARBON BLACK PARTICLES, PASSING THE OTHER STREAM THROUGH A CONDUIT WHEREIN THE CARBON BLACK PARTICLES IN SAID OTHER STREAM COME INTO CONTACT WITH SECOND METALLIC SURFACES HAVING A LOWER WORK FUNCTION THAN THE CARBON BLACK PARTICLES THEREBY TO IMPART A NEGATIVE CHANGE TO THE CARBON BLACK PARTICLES AND A POSITIVE CHARGE TO THE METALLIC SURFACES AND CONTINUOUSLY DRAWING OFF THE POSITIVE CHARGES FROM SAID METALLIC SURFACES SO AS TO AVOID ACCUMULATION OF POSITIVE SURFACE CHARGES ON SAID SECOND METALLIC SURFACES, THE MAGNITUDE OF THE NEGATIVE CHARGES ACQUIRED BY SAID CARBON BLACK PARTICLES IN SAID OTHER STREAM BEING DEPENDENT UPON THE RELATIVE WORK FUNCTIONS OF SAID SECOND METALLIC SURFACES AND SAID CARBON BLACK PARTICLES, AND THEREAFTER MIXING THE TWO STREAMS TOGETHER TO EFFECT AGGLOMERATION OF CARBON BLACK PARTICLES FROM THE ONE STREAM WITH CARBON BLACK PARTICLES FROM THE OTHER STREAM WITH THE SIZE OF THE RESULTING AGGLOMERATES BEING DEPENDENT UPON THE MAGNITUDE OF THE CHARGES CARRIED BY THE RESPECTIVE PARTICLES FROM THE TWO STREAMS.

Claim 2

THE METHOD OF ALLOMERATING CARBON BLACK PARTICLES IN THE EFFLUENT SMOKE FROM CARBON BLACK FURNACES AND SEPARATING SAID CARBON BLACK PARTICLES FROM SUBSTANTIALLY ALL OF THE GASEOUS PORTION OF SAID SMOKE, COMPRISING DIVIDING THE SMOKE INTO TWO STREAMS, PASSING ONE STREAM THROUGH A CONDUIT WHEREIN IN CARBON BLACK PARTICLES IN SAID ONE STREAM COME INTO CONTACT WITH FIRST METALLIC SURFACES HAVING A HIGHER WORK FUNCTION THAN THE CARBON BLACK PARTICLES THEREBY TO IMPART A POSITIVE CHARGE TO THE CARBON BLACK PARTICLES AND A NEGATIVE CHHANGE TO THE METALLIC SURFACE AND CONTINUOUSLY DRAWING OFF THE NEGATIVE CHARGES FROM SAID METALLIC SURFACES SO AS TO AVOID ACCUMULATION OF NEGATIVE SURFACE CHARGES ON SAID FIRST METALLIC SURFACES, THE MAGNITUDE OF THE POSITIVE CHARGE ACQUIRED BY SAID CARBON BLACK PARTICLES IN SAID ONE STREAM BEING DEPENDENT UPON THE RELATIVE WORK FUNCTIONS OF SAID FIRST METALLIC SURFACES AND SAID CARBON BLACK PARTICLES, PASSING THE OTHER STREAM THROUGH A CONDUIT WHEREIN THE CARBON BLACK PARTICLES IN SAID OTHER STREAM COME INTO CONTACT WITH SECOND METALLIC SURFACES HAVING A LOWER WORK FUNCTION THAN THE CARBON BLACK PARTICLES THEREBY TO IMPART A NEGATIVE CHANGE TO THE CARBON BLACK PARTICLES AND A POSITIVE CHARGE TO THE METALLIC SURFACES AND CONTINUOUSLY DRAWING OFF THE POSITIVE CHARGES FROM SAID METALLIC SURFACES SO AS TO AVOID ACCUMULATION OF POSITIVE SURFACE CHARGES ON SAID SECOND METALLIC SURFACES, THE MAGNITUDE OF THE NEGATIVE CHARGES ACQUIRED BY SAID CARBON BLACK PARTICLES IN SAID OTHER STREAM BEING DEPENDENT UPON THE RELATIVE WORK FUNCTIONS OF SAID SECOND METALLIC SURFACES AND SAID CARBON BLACK PARTICLES, AND THEREAFTER MIXING THE TWO STREAMS TOGETHER TO EFFECT AGGLOMERATION OF CARBON BLACK PARTICLES FROM THE ONE STREAM WITH CARBON BLACK PARTICLES FROM THE OTHER STREAM WITH THE SIZE OF THE RESULTING AGGLOMERATES BEING DEPENDENT UPON THE MAGNITUDE OF THE CHARGES CARRIED BY THE RESPECTIVE PARTICLES FROM THE TWO STREAMS.
