Filed: 1932-10-14
Abstract: 408,681. Drying cigarettes. MOLINS, W. E., 2, Evelyn Street, Deptford, London. Oct. 14, 1932, No. 28792. [Class 34 (ii).] Apparatus for drying and conditioning cigarettes comprises a movable carrier for cigarettes, and one or more pairs of air ducts, the outlet ports of each pair of ducts being arranged in axial alignment with and at opposite ends of a cigarette to be received between them on a carrier, and are also movable with the carrier. In the form shown, cigarettes pass from a conveyer 10 to a pair of discs 11, from which they are transferred to the grooves 29 provided on rotating drums 13 and 14, or 14 and 15. From the discs mounted on drums such as 14, the cigarettes are transferred to a further set of discs such as 24 by means 36, and are finally removed therefrom and transferred to a delivery conveyer by means 39. The drums 13, 14, 15 are mounted on a hollow shaft 16 divided into segments 18, 20, 21 by partitions 17. When the cigarettes are in position, air delivered to the inlet casing 22 passes from the segments 20 and 21 into the drum 14, through nozzles 27 into the cigarettes, out through nozzles 28 into the drums 13 and 15, and so to the segment 18 and the outlet casing 26. On the second set of drums, the inlet nozzles are formed on the outer drums, so that the air current passes through the cigarettes in the opposite direction to the first current. To facilitate the feeding of the cigarettes to and from the treatment discs, the nozzles 28 are pressed inwardly by springs, and are forced back at the transfer points by cams 31 and 37. The drums may be adjusted axially to suit cigarettes of various lengths. The air used may be forced through under pressure or drawn through by suction, and any desired flavouring for the tobacco may be imparted to the air, which may also be preheated.

Abstract: 388,853. Coking processes. POTTS, H. E., 12, Church Street, Liverpool.-(Soc. de Recherches et de Perfectionnements Industriels ; 125, Avenue du President Wilson, Puteaux, Seine, France.) Oct. 20, 1931, No. 29084. [Class 55 (i).] In the distillation of coal or coal briquettes by the passage therethrough of a heating gas in order to obtain a smokeless fuel, the heat of the circulating gas is maintained by internal combustion of the distillation products in a controlled oxygen supply. Residual oxygen is present in the preliminary stages to harden the carbonaceous material and prevent swelling. Pulverized coal or oil vapour, or spray, may be added to the circulating gas. The material is heated in stages of increasing temperature in a closed circuit of heating gas, the maximum temperature being about 700‹ C. Suitable apparatus comprises three distillation retorts 1, 2, 3, and a fourth retort 4 in which the charge is cooled while preheating the circulating gas. The heating gas from the coolest retort 1 is drawn by a fan 13 through a condenser 24, and forced through another condenser 14 for removing oil, and through the hot charge in retort 4, surplus gas being withdrawn through a valve 50. The heated gas passes to a mixing chamber 46 filled with refractory material, and then through pipe 17 into retort 3, the circuit being completed through mixing chamber 45, retort 2, mixing chamber 44, and retort 1. Mazout, tar or the like is burned in combustion chambers 41, 42, 43 by jets 38, 39, 40 fed with air from pipe 51, by which means the retorts are preliminarily heated. A basket containing the charge is first put into retort 1 and then moved into retorts 2 and 3 in succession until these retorts are full. The supply of mazout is diminished, and additional air is fed to chambers 47, 48, and 49 through valves 30, 33, and 36 and the distillates supply sufficient heat by their combustion. Valves 29, 32 and 35 may be opened to admit air to the bottom of the retorts, for combustion, and to harden the surface of the charge. In a modification, the heat necessary for distillation is only produced in two of these stages.

Title: Improvements in or relating to free-stroke piston internal combustion engines
IPC: F02B71/00
Filed: 1939-11-01
Abstract: 536,101. Regulating; oil engines. SULZER FRERES SOC. ANON. Nov. 1, 1939, No. 29151. Convention date, Nov. 15, 1938. [Classes 7 (iii) and 7 (vi)] In a free-stroke piston engine, the fuel is injected in accordance with the pressure in the working cylinder by a pump which is positively actuated on its delivery stroke by means controlled by an impulse-transmitter influenced by the cylinder pressure. In the form shown in Fig. 1, the engine pistons 3 are connected to aircompressors 2 supplying a reservoir 4 connected to the inlet pipe 4<1>, exhaust occurring at 5, and fuel is injected at 30 by a pump 26 which is actuated by a constant air or gas pressure supplied by a pump 23 and pipe 17 past a valve 16, which is controlled by a lever 15 and plunger 7 acted on by the cylinder pressure through a pipe 6<1>. Fuel is supplied to the chamber of the pump 26, by a pump 27, which effects the return stroke of the pump 26, limited by an adjustable arm 31, when the cylinder pressure falls sufficiently for the plunger 7 to fall and move the valve 16 to cut off the pressure-supply pipe 17. The valve 16 may also be controlled by the pressure in the reservoir 4 acting on a plunger 11. The pressure in the exhaust pipe 5 may act on the plunger 7. In a modification, the delivery stroke of the pump 26 is effected by a spring which is released by a catch controlled by the plungers 7 and 11, the return stroke of the pump being effected by a cam driven from the pistons 3. A liquid column 46 may be interposed in the pipe 5<1>, Fig. 4, which also shows a safety device for preventing fuel injection when the cylinder pressure is too high. In such an event, the plunger 7 is raised sufficiently to move an additional control valve 51 so as to connect the pressure-supply pipes 17, 52, 53 to a vent 54, whereupon a piston 55 is moved by a spring 57 to connect a chamber 58 to a vent 63, thus allowing a piston 59 and valve 60 to lift and byepass the fuel from the pipe 61, so that no injection takes place at 30. The piston 55 is returned by a handle 64 to cause the valve 60 to close. The liquid 46, which may be lubricating oil, is suplied by a pump 50, against the pressure of air supplied at 49 past a non-return valve 48. In a modification, this non-return valve is arranged in the plunger 7.
