Gas lifting carbon black pellets

Claim 1

A CARBON BLACK PELLETING AND STORAGE APPARATUS COMPRISING IN COMBINATION A PELLET MILL HAVING A FEED MEANS AND A DISCHARGE MEANS, A STORAGE BIN, A DISENGAGING TUBE ON TOP OF AND COMMUNICATING FREELY WITH THE SAID STORAGE BIN, A PNEUMATIC CONVEYOR ADAPTED TO RECEIVE CARBON BLACK FROM THE DISCHARGE MEANS OF THE SAID PELLET MILL AND FOR CONVEYING THE SAID CARBON BLACK TO THE BOTTOM OF THE SAID DISENGAGING TUBE; THE SAID PENUMATIC CONVEYOR BEING FLARED OUTWARDLY AT ITS OUTLET END SO AS TO DISTRIBUTE SAID CARBON BLACK UNIFORMLY UPWARD AND OVER THE ENTIRE CROSS SECTIONAL AREA OF SAID DISENGAGING TUBE,HAVTHE SAID OUTLET END BEING DISPOSED UPWARD AND WITHIN THE SAID DESENGAGING TUBE; THE SAID DISENGAGING TUBE HAVING A CROSS SECTIONAL AREA SUBSTANTIALLY GREATER THAN THAT OF THE SAID PNEUMATIC CONVEYOR AND BEING OF SUFFICIENT HEIGHT TO ALLOW CARBON BLACK OF A PREDETERMINED MINIMUM SIZE TO COME TO REST AND REVERSE ITS DIRECTION GRAVITATING TO THE SAID STORAGE BIN; MEANS FOR REMOVING GAS AND CARBON BLACK OF LESS THAN THE SAID PREDETERMINED SIZE FROM THE SAID DISENGAGING TUBE; MEANS FOR SEPARATING CARBON BLACK FROM GAS; MEANS FOR PASSING SAID REMOVED GAS AND CARBON BLACK TO SAID SEPARATOR WHEREIN MOST OF THE CARBON BLACK TO SAID SEPARATOR WHEREIN MOST OF PASSING THE THUS SEPARATED CARBON BLACK TO THE SAID PELLET MILL; AND MEANS FOR PASSING THE GAS FROM THE SAID SEPARATOR TO THE SAID PNEUMATIC CONVEYOR..

Claim 3

THE METHOD OF PREPARING CARBON BLACK FOR TRANSPORTATION WHICH COMPRISIES PASSING CARBON BLACK THROUGH A PELLETING ZONE THEREBY FORMING PELLETS, WITHDRAWING SAID PELLETS FROM SAID PELLETING ZONE, SUSPENDING SAID WITHDRAWN PELLETS IN A GASIFORM STREAM, PASSING SAID STREAM THROUGH A LONGITUDINALLY EXTENSIVE ZONE OF RESTRICTIVEE CROSS SECTION AT A VELOCITY SUFFICIENT TO TRANSPORT THE SUSPENDED CARBON BLACK THROUGH SAID ZONE, ELEVATING THE SAID SUSPENDED CARBON BLACK IN SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA TO HEIGHT WELL ABOVE THE LEVEL OF INTRODUCING SAID CARBON BLACK TO SAID GASIFORM STREAM, DISCHARGING SAID STREAM FROM SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA UPWARDLY AND UNIFORMLY INTO A LONGITUDINALLY EXTENSIVE ZONE OF GREATER CROSS SECTIONAL AREA THAN SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA WHEREIN THE VELOCITY OF SAID STREAM IS REDUCED AND PART OF THE CARBON BLACK IS DISENGAGED FROM SAID GASIFORM STREAM TO SETTLE GENTLY TOWARD THE BOTTOM OF SAID ZONE OF GREATER CORSS SECTIONAL AREA THROUGH THE ASCENDING GASIFORM STREAM, WITHDRAWING THE DISENGAGED CARBON BLACK FROM THE BOTTOM OF SAID ZONE OF GREATER CROSS SECTIONAL AREA. WITHDRAWING THE REST OF SAID CARBON BLACK SUSPENDED IN SAID STREAM FROM A REGION OF SAID ZONE OF GREATER CROSS SECTIONAL AREA ABOVE THE HIGHEST LEVEL OBTAINED BY THE DISENGAGED CARBON BLACK, BLOWING THE SAID WITHDRAWN CARBON BLACK SUSPENDED IN SAID STREAM TO A SEPARATION ZONE, SEPARATING SUBSTANTIALLY ALL OF THE STILL SUSPENDED CARBON BLACK FROM THE GASIFORM STREAM IN SAID SEPARATING ZONE, SETTLING THE SEPARATED CARBON BLACK TO THE BOTTOM OF THE SAID SEPARATING ZONE, WITHDRAWING THE GASIFORM STREAM FROM SAID SEPARATING ZONE, PASSING THE THUS WITHDRAWN BLACK FREE GASIFORM STREAM IN A LONGITUDINALLY EXTENSIVE ZONE OF RESTRICTED CROSS SECTIONAL AREA TO THE POSITION OF INTRODUCING THE CARBON BLACK PELLETS THEREBY SERVING AS SAID GASIFORM STREAM, WITHDRAWING THE SEPARATED CARBON BLACK FROM THE BOTTOM OF SAID SEPARATING ZONE, AND INTRODUCING THE LAST SAID WITHDRAWN CARBON BLACK TO THE CARBON BLACK PASSING THROUGH THE PELLETING ZONE.

Claim 4

THE METHOD OF PREPARING CARBON BLACK FOR TRANSPORTATION WHICH COMPRISIES PASSING CARBON BLACK THROUGH A PELLETING ZONE THEREBY FORMING PELLETS, WITHDRAWING SAID PELLETS FROM SAID PELLETING ZONE, SUSPENDING SAID WITHDRAWN PELLETS IN A GASIFORM STREAM, PASSING SAID STREAM THROUGH A LONGITUDINALLY EXTENSIVE ZONE OF RESTRICTIVEE CROSS SECTION AT A VELOCITY SUFFICIENT TO TRANSPORT THE SUSPENDED CARBON BLACK THROUGH SAID ZONE, ELEVATING THE SAID SUSPENDED CARBON BLACK IN SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA TO HEIGHT WELL ABOVE THE LEVEL OF INTRODUCING SAID CARBON BLACK TO SAID GASIFORM STREAM, DISCHARGING SAID STREAM FROM SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA UPWARDLY AND UNIFORMLY INTO A LONGITUDINALLY EXTENSIVE ZONE OF GREATER CROSS SECTIONAL AREA THAN SAID ZONE OF RESTRICTED CROSS SECTIONAL AREA WHEREIN THE VELOCITY OF SAID STREAM IS REDUCED AND PART OF THE CARBON BLACK IS DISENGAGED FROM SAID GASIFORM STREAM TO SETTLE GENTLY TOWARD THE BOTTOM OF SAID ZONE OF GREATER CORSS SECTIONAL AREA THROUGH THE ASCENDING GASIFORM STREAM, WITHDRAWING THE DISENGAGED CARBON BLACK FROM THE BOTTOM OF SAID ZONE OF GREATER CROSS SECTIONAL AREA. WITHDRAWING THE REST OF SAID CARBON BLACK SUSPENDED IN SAID STREAM FROM A REGION OF SAID ZONE OF GREATER CROSS SECTIONAL AREA ABOVE THE HIGHEST LEVEL OBTAINED BY THE DISENGAGED CARBON BLACK, BLOWING THE SAID WITHDRAWN CARBON BLACK SUSPENDED IN SAID STREAM TO A SEPARATION ZONE, SEPARATING SUBSTANTIALLY ALL OF THE STILL SUSPENDED CARBON BLACK FROM THE GASIFORM STREAM IN SAID SEPARATING ZONE, SETTLING THE SEPARATED CARBON BLACK TO THE BOTTOM OF THE SAID SEPARATING ZONE, WITHDRAWING THE GASIFORM STREAM FROM SAID SEPARATING ZONE, PASSING THE THUS WITHDRAWN BLACK FREE GASIFORM STREAM IN A LONGITUDINALLY EXTENSIVE ZONE OF RESTRICTED CROSS SECTIONAL AREA TO THE POSITION OF INTRODUCING THE CARBON BLACK PELLETS THEREBY SERVING AS SAID GASIFORM STREAM, WITHDRAWING THE SEPARATED CARBON BLACK FROM THE BOTTOM OF SAID SEPARATING ZONE, AND INTRODUCING THE LAST SAID WITHDRAWN CARBON BLACK TO THE CARBON BLACK PASSING THROUGH THE PELLETING ZONE.
