THE METHOD OF CHANGING THE TEMPERATURES OF OBJECTS HAVING INITIAL TEMPERATURES TO BE CHANGED, WHICH COMPRISES THE STEPS OF: (A) MOVING A SUCCESSION OF SAID OBJECTS AT SAID INITIAL TEMPERATURES WITH A MOVING SUPPORTING CONVEYOR, (B) MOVING SAID CONVEYOR AND THE OBJECTS THROUGH A TEMPERATURE-CONDITIONING ZONE IN A LONGITUDINAL DOWNSTREAM DIRECTION, (C) FORMING A SHEET OF CONDITIONING GAS HAVING A HIGH VELOCITY RELATIVELY TO SAID MOVING OBJECTS BY (1) FLOWING A SERIES OF HIGH-VELOCITY, OVERLAPPING GAS JETS HAVING TEMPERATURES DIFFERENT FROM SAID INITIAL TEMPERATURES FROM SPACED POINTS WITHIN SAID CONDITIONING ZONE, (2) SAID JETS BEING INCLINED AT ANGLES LESS THAN 30* TO A LINE JOINING SAID POINTS AND BEING SO DIRECTED AND SO CLOSELY SPACED THAT EACH JET, SAVE THAT AT AN END OF THE SERIES, ISSUES SUBSTANTIALLY PARALLEL TO AT LEAST ONE OTHER JET, AND SUCCESSIVE JETS OF THE SERIES JOINTLY FORM SAID GAS SHEET, AND (D) SWEEPING SAID OBJECTS WHILE MOVING THROUGH SAID ZONE WITH SAID GAS SHEET AT HIGH RELATIVE VELOCITY TO EFFECT A RAPID CHANGE IN THE TEMPERATURE THEREOF.
