Title: Process of gasifying solid combustible materials
IPC: C10J3/08
Filed: 1953-06-08
Abstract: 744,153. Gasifying solid fuels. UNION RHEINISCHE BRAUNKOHLEN KRAFTSTOFF AKT.-GES. June 8, 1953 [June 19, 1952], No. 15767/53. Class 55 (1). In a process of producing combustible gases by gasifying solid fuels in a bath of their own liquid slag which is maintained in a cyclic current between a heating space 1 and a gasifying space 2 wherein the fuel is gasified by introduction of an endothermic gasifying agent, e.g. steam, the gases produced in the space 2 are treated after they have left the slag to increase the hydrocarbon content thereof by adding fuel thereto while avoiding contact between the fuel thus added and the slag. The fuel added to increase the hydrocarbon content may be coal, lignite, peat, oil shale or a liquid or a gaseous fuel and it may be added at a point at which the heat emitted by the slag is still effective. The heat, of the slag bath may be effective only for a short time to produce unsaturated hydrocarbons and the gases are then chilled or otherwise treated to preserve the equilibria of the unsaturated hydrocarbons produced. In the form shown, the gasifying apparatus is adapted to use a solid fuel, e.g. lignite, as the fuel for enriching the gasification gases also includes a distillation space 3, a coke separator 4, a fuel drier 5, a separator 6 for separating the fuel dried whilst in suspension in hot gases, a washer 7, a waste-heat boiler 8 and a feed-water pre-heater 9. Ducts 15 and 16 supply air and feed-water, and the duct 17 leads flue gas from the heating space 1 to the outer atmosphere, and the duct 18 removes steam from the boiler. Lignite pre-dried to 15 per cent water content is fed from line 10 into the hot gas stream from the distillation space 3 and is carried through the drier 5. Dried lignite containing 2 per cent water is led partly by duct 11 to the gasifying space 2 with the aid of steam or other conveying medium introduced through duct 12, and partly by duct 14 to a point where it is entrained in the hot gases leaving the gasifying space 2. Steam may be added to the gases entering the distillation space 3 through duct 13. The fuel not gasified in space 2 is carried in the slag into the heating space 1 and coke is added by a duct from cokeseparator 4. The slag is reheated by combustion of the fuel contained therein with air added by duct 15 and combustion gases pass out through waste heat boiler 8, feed-water pre-heater 9 and duct 17. Coke from separator 4 may also be added to the gasifying space 2. The hot gases leave the gasifying space 2 at about 1500‹ C. and after passing through the distillation space 3 and coke separator 4 enter the coal drier at about 750‹ C. Combustible gas is led off by duct 19. In a modification the gases leaving the gasifying space may be enriched by passing the gases over a catalyst, e.g. one containing nickel, to convert some of the carbon monoxide and hydrogen into methane and water. Specification 666,119 is referred to.

Abstract: 356,109. Thermionic valves. LOEWE, S., 10, Wiesenweg, Steglitz, Berlin. May 22, 1930, No. 15838. Convention date, May 22, 1929. [Class 39 (i).] In thermionic valves in which magnesium or other getter substance for improving the vacuum is vaporized after the electrodes have been freed from gas, the getter and the electrodes being heated independently, the getter is disposed at the inner side of the anodes of the one or more electrode systems of the valve so that the anodes are coated with getter and protect the main portion of the envelope from deposit. The anodes 2, 3, Fig. 3, of separate electrode systems may form a ring enclosing the getter which is arranged on a loop within the ring or is at the centre 10 and forms part of a loop such as 11 or 11<1> passing around one electrode system. The anodes 2, 3 are first heated, without heating the getter 10, by a high-frequency coil in the position I and then the getter 10 is heated without heating the anodes, by turning the coil through 90‹ into the position II to induce currents in the loop. The getter is deposited on faces of the anodes not subject to electron emission and cooling fins 4, 5 on the anodes can radiate heat through clear parts of the envelope. The deposit on the anodes vaporizes continuously during normal working of the valve to maintain the vacuum. In a modification, the anodes of two electrode systems, which may have flat cooling surfaces and may be parallel, are connected by two conductors to form a loop, one or both conductors carrying the getter. In another modification, a single annular electrode system surrounds the getter. In another modification, Fig. 5, the getter 16 is within a ring formed by five electrode systems 17 .. 21 and by a disc 22 in which currents are induced to heat the getter. In all cases, a further getter may be vaporized during manufacture of the valve in a space partitioned off by a screen. The invention may be applied to rectifying and generator valves but is particularly applicable to high-power amplifiers.

Title: Tail-less aeroplane constituted by a three-element wing
IPC: B64C39/10
Filed: 1931-06-01
Abstract: 375,515. Tailless aeroplane. CHARPENTIER, J. F. G. M. L., 5, Rue TahÚre, St. Cloud, Seine-et-Oise, France. June 1, 1931, No. 15977. Convention date, June 4, 1930. [Class 4.] A tailless aeroplane comprises a central part 1, Fig. 1, having a negative moment coefficient at zero lift, and two outer symmetrical parts 2, 3 of considerably smaller maximum chord each separated by a plane of discontinuity from the central part and together having a surface area substantially equal to that of the central part. The portion 1 may have a separately adjustable trailing edge flap 4 for altering its camber, and may also carry a fixed fin 11 and rudder 10. Passengers, goods, engines, &c. are contained in the part 1 and in some cases in the root portions of wings 2, 3. Wings 2, 3 have hinged leading and trailing edges 6, 7 and 8, 9 respectively which are operable as elevators as shown in Figs. 4 and 5. The parts 8, 9 may be divided as shown at 8, 8<1>, Fig. 7, and the trailing parts 8<1> may be operated independently of parts 8 as ailerons for lateral control. Alternatively separate ailerons situated toward the wing tip such as 7<1>, 9<1>, Fig. 1, may be employed, or means may be provided for operating the flaps 8, 9 differentially. Steering may be effected by the rudder 10 if fitted or by oppositely movable flaps 32, 33, 32<1>, 33<1> at the wing tips, Figs. 1 and 11. Control of the flaps 6, 8 may be effected by means of cables 15, 16, Fig. 13, acting on a lever 12 fulcrumed at either end on abutments 18, 19 respectively and connected by rods 13, 14 to the pivoted flaps. A pull on cable 15 causes the lever 12 to rock about the stop 19 and thus to depress the flap 8 leaving flap 6 unaffected ; a pull on cable 16 has the contrary effect. The parts 81 are independently actuated. In the form shown the aeroplane has a dihedral on both surfaces and is shaped at its underside to form a hull surface which may be adapted for landing and taking off on the water. Central wheels 23 and retractable side wheels 24, 25, Fig. 2, disposed under the motors are provided. The tyres of the lateral wheels are stated to act as floats when the aeroplane alights on water. According to the Specification as open to inspection under Sect. 91 (3) (a) the central wheels 23, Fig. 16 (Cancelled), are secured to the wing framework by shock absorbers 26, the wheel axles being provided with a fairing 27 which continues the shape of the boat-like hull in flight. This subject-matter does not appear in the Specification as accepted.
