Title: An installation for the heat treatment of fine grain granular fuel
IPC: C10B49/08
Filed: 1960-11-04
Abstract: In an installation for extracting water and gas from and for the coking of fine grained fuels, e.g. brown coal or hard coal up to 15 mm. grain size, hot gases from the combustion chamber 1 pass through centrifugal separators 5, 6, 9 by way of pipe lines 4, 7, 8 and the fuel is fed from the hopper 23 into the pipeline 8 from where it passes through the separators in the reverse order to the hot gases, i.e. 9, 6, 5, the pipe lines and separators acting as heat exchangers.  The fuel is dried in the first heat exchanger at a temperature 100 DEG -250 DEG C. in under 10 sec., preferably 1-5 sec., and preliminary degasification occurs in the second and third heat exchangers at 250 DEG -500 DEG C. in under 20 sec., preferably 3-12 sec., the degasified fuel being then coked in the oven 36 after passing through the bunker 18 and charging truck 35.  The gas produced in the heat exchangers 5 and 6 is partly drawn off at 34 before reaching the water extracting stage.  Some of the gas may be burned in the combustion chambers 30 or 32 to provide heat for the degasification or water extraction.  Gas leaving the separator 9 is burned in the combustion chamber 45 to <PICT:0936999/III/1> render it inert.  Dust is removed from the inert gas by the separator 11 and water vapour by the condenser 13, the gas being drawn through the apparatus by a blower 15 and released either to the atmosphere or fed into the heat exchanging system, bunker 18 or oven charging truck 35 as required.  In a modification (Fig. 2, not shown) the coking is not carried out in the oven 36 but in a further heat exchanger formed by a pair of separators connected similarly to the other separators between the separator 5 and the bunker 18.

Title: Improvements in or relating to cracking or gasifying hydrocarbons
IPC: C01B3/34
Filed: 1958-11-26
Abstract: Hydrocarbons are cracked by passing hot gasses in a circulatory path along the inside <PICT:0865732/IV (b)/1> <PICT:0865732/IV (b)/2> wall of a cylindrical reactor, and then through an annulus defined by the reactor wall and an inner tube, and passing the hydrocarbon to be cracked in the reverse direction, first through the inner tube and then through the circulating gases, preferably so that the hydrocarbon is heated in the inner tube to a temperature below 900 DEG C. and afterwards to a temperature above 900 DEG C.  In the apparatus of Fig. 1, combustion gases, which must be free from oxygen, are introduced tangentially into reaction chamber 1 from combustion chambers 3, in such a manner that the flame reaches the inner portion and the gases flow in a helical path downwards until they reach the lower section, where they pass through the annulus between the reactor and tube 6.  Part or all of the gases may then be removed or passed upwards through the inner tube.  The hydrocarbon to be cracked is injected through atomiser 8, preferably with a carrier gas, and, if desired, through sprays 9. The product is removed through pipe 4.  In the arrangement of Fig. 3, the products are drawn upwards by impeller 14, part only being removed through pipe 18, the remainder being returned tangentially round baffle 15 and down the inside wall of the reactor.  Air or oxygen is then injected tangentially through openings 16 to form the heating gas by combustion.ALSO:<PICT:0865732/III/1> <PICT:0865732/III/2> Hydrocarbons are cracked by passing hot gases in a circulatory path along the inside wall of a cylindrical reactor, and then through an annulus defined by the reactor wall and an inner tube, and passing the hydrocarbon to be cracked in the reverse direction, first through the inner tube and then through the circulating gases, preferably so that the hydrocarbon is heated in the inner tube to a temperature below 900 DEG C. and afterwards to a temperature above 900 DEG C.

Abstract: 868,220. Grinding. ELLIOTT & CO. Ltd., B. March 7, 1960 [Dec. 8, 1958], No. 39468/58. Class 60. A surface grinding machine comprises a grinding wheel 2 adapted to grind the surface of a workpiece mounted on a work-table d movable to-and-fro relative to a saddle b which, in turn, is movable to-and-fro relative to a base 4 at right angles to the movement of the work-table, and a control system whereby either both the saddle and work-table are reciprocated to effect criss-cross grinding, or one part, for example, the work-table, is reciprocated while the other part, the saddle, is moved step-by-step unidirectionally. The grinding wheel is belt or chain driven from an electric motor 9 and is carried by a slide 3 vertically-adjustable relative to the base 4. The saddle b is movable relative to the base by a piston-and-cylinder device, the cylinder a being secured to the saddle and the rod of the piston a<SP>1</SP> being secured to the base. A piston c<SP>2</SP> is secured to the saddle and is disposed in a cylinder C secured to the work-table to reciprocate the latter relative to the saddle. The alternate ends of the work-table cylinder are supplied with hydraulic pressure from a pump f under the control of a reversing valve c<SP>1</SP> actuated at the end of each stroke, or each alternate stroke, of the table by pressure supplied to alternate ports i<SP>1</SP>, i2 by the movement of a valve h actuated by dogs on the work-table. A control valve j, adjustable throttle valve l and pressure relief valve k are incorporated in the work-table circuit The saddle cylinder a is supplied with hydraulic pressure from a circuit having a pump e and a valve n which, in the position shown, directs the fluid from a control valve m to a valve o reversible at the end of each stroke of the saddle by dogs on the saddle to supply fluid to the alternate ends of the cylinder a. When the valve n is moved to its alternative position, the supply from the pump e is directed to a valve q which is movable to alternate positions where the valve h is actuated to reverse the valve i and the direction of movement of the work-table, and supplies fluid to the alternate ends of a metering valve r. Each time the valve q is actuated, a piston r<SP>1</SP> of the metering valve permits a small quantity of fluid to be supplied to the cylinder a to provide the step-by-step movement of the saddle, the amount of fluid supplied being determined by an adjustable stop r<SP>4</SP>. When the saddle has reached the end of its stroke, the valve o is actuated to reverse the direction of the step-by-step movements. In other embodiments the metering valve is actuated mechanically each time the work-table reaches the end of its stroke, and hydraulic paddle motors may replace the work-table and saddle piston-andcylinder devices.
