[Classes 34 (i) and 34 (ii)] [See also Group VI] In the preparation of tobacco for the manufacture of cigarettes, the tobacco leaves are cut by means of an intermeshing-disc cutting- machine, then conveyed through a drying chamber by conveying means located within the chamber, and dried by circulation of dry or predried air through the chamber. In the construction shown in Fig. 1, a cutting device comprising intermeshing rotary cutting- discs 3, 4 is provided for cutting tobacco before its entry into a chamber 6. Dry air is circulated through the chamber, the air preferably being heated by heating appliances 7 near the entry 8. The air may also be heated during its passage through the chamber. The cutting machine may be of the type described in Specifications 430,766, [Group I], and 435,571, [Group VIII]. A series of endless conveyers 9, 10, 11, 12, and 17 is mounted in the chamber so that the tobacco entering at 5 is fed from one conveyer to another. The drying air directed by baffles 16 flows in countercurrent to the travel of the tobacco. Paddle wheels 13 are provided at the delivery end of the conveyers 9, 10 for the purpose of projecting the heavy mid-rib portions of the tobacco into compartments 14. Paddle wheels 15 are also provided in association with the conveyers 11, 12 to open out and turn over the tobacco. The outlet 18 may be provided with two flap valves 19, 20, each adapted to open under a predetermined weight of tobacco, so that escape of drying air is avoided. Hygrometers 21 and thermometers 22 may be provided to indicate the humidity and temperature conditions prevailing.

Abstract: A material for use in recording the application thereto of electrical energy, e.g. as a spark, comprises an electrically conductive paper base and superimposed thereon a layer of cellulose acetate butyrate which has been deposited under conditions which cause it to be light-diffusing, the layer also containing a pigment.  The layer may be deposited in a light-diffusing condition by applying it from a solution in a medium containing both solvent and non-solvent and drying it in moist air.  The paper base may be made conductive by impregnating or coating it with carbon black.  When a coating is used, it lies between the base and the cellulose acetate butyrate layer.  When the paper is impregnated, a protective layer may be applied to the back, i.e. the side away from the cellulose acetate butyrate.  A conductive coating of, e.g. carbon black and a binder, e.g. an alkyd resin, polystyrene, polyvinyl chloride or cellulose ester, may be applied to a paper loaded with a conductive pigment, e.g. carbon black.  Pigments for the cellulose acetate butyrate layer may be lead and copper thiosulphates and thiocyanates and zinc sulphide and oxide.  The solvent may be methyl ethyl ketone, and the non-solvent light petroleum.
