Zusammenfassung:TOBACCO IS FED TO A CYLINDER (4) CARRIED BY AN INDEXING ROTARY TABLE (2) WHICH CARRIES THE CYLINDER THROUGH FOUR STATIONS IN SUCCESSION. AT THE SECOND STATION THE TOBACCO IS COMPACTED (BY PISTON 1.3). AT THE THIRD STATION THE TOBACCO BATCH IS TRANSFERRED CO A PRESSURE VESSEL (1.4> AND IS COOLED BY FLOWING CARBON DIOXIDE GAS THROUGH THE BATCH. THE OUTLET (32''> IS THEN CLOSED AND THE PRESSURE OF THE GAS IS RAISED TO EFFECT IMPREGNATION. THE INITIAL COOLING IS SUCH THAT A CONCRO11ED AMOUNT OF CARBON DIOXIDE CONDENSES ON THE TOBACCO. THE PRESSURE IS THEN RELEASED AND THE EXPANSION OF THE GAS AND EVAPORATION OF THE LIQUID CARBON DIOXIDE COOLS THE IMPREGNATED TOBACCO. AT THE FOURTH STATION THE TOBACCO IS DISCHARGED (1.7) AND IS SUBSEQUENTLY EXPANDED BY HEARING.
