Process for producing carbon black

Claim 1

THE CONTINUOUS PROCESS OF PRODUCING CARBON BLACK WITHIN A CLOSED RETORT AND FROM A HYRROCARBON BY A CONTINOUOUS REACTION STARTING WITHIN AN UNOBSTRUCTURED PRIMARY PASSAGE OF A GENERALLY CIRCULAR CROSS-SECTION AND FORMED BY ONE END OF SAID RETORT, SAID REACTION THEREAFTER BEING CONFIRM AND COMPLETED WITHIN A SINGLE UNINTERRUPTED ANNULAR PASSAGE AT THE OPPOSITE SIDE OF SAID RETORT AND SUBSTANTIALLY CONCENTRIC WITH AND COMMUNICATING WITH SAID PRIMARY PASSAGE, WHICH COMPRISES INTRODUCING AN OUTER FLOW OF AIR AND A POTENTIALLY REACTIVE HYDROCARBON AT ONE END OF AND NEAR THE SIDE WALL OF SAID PRIMARY PASSAGE THE QUANTITY OF AIR BEING SUFFICIENT FOR THE SUBSUBSTANTIALLY CIMPLETE COMBUSTION OF SAID OUTER FLOW OF A POTENTIALLY REACTIVE HYDROCARBON, SIMULTANOEUSLY INTRODUCING A SEPERATE ANS SUBSTANCIALLY CENTRAL FLOW OF A POTENTIALLY REACTIVE HYDROCARBON TO THE SAME END OF SAID PRIMARY PASSAGE AND WITHIN SAID OUTER FLOW OF AIR AND HYDROCARBON, INITATING SAID CONTINOUS REACTION BY SUBDSTANTIALLY COMPLETELY COMBUSTING SAID OUTER FLOW OF AIR AND HYDROCARBON AND SUBJECTING SAID CENTERAL FLOW OF A POTENTIALLY REACTIVE HYDROCARBON TO THE HEAT OF COMBUSTION OF SAID OUTER FLOW TO INCRASE THE TEMPERATURE OF SAID CENTRAL FLOW, INDUCING ALL OF THE PRODUCTS OF REACTION TO FLOW INTO SAID ANNULAR PASSAGE, SIMULTANEOUSLY INTRODUCING A SECOND FLOW OF AIR AT THE OPPOSITE END OF SAID RETORT THRU THE CEN-
