Title: A furnace adapted for the combustion of small solid fuel, particularly pulverised fuel
IPC: F23C7/06
Filed: 1950-08-24
Abstract: 685,082. Pulverulent-fuel furnaces. CZECHOSLOVAK HEAVY ENGINEERING WORKS, and CERMAK, J. Aug. 24, 1950 [Aug. 24, 1949], No. 20938/ 50. Class 51 (i). In a pulverulent-fuel fired furnace the combustion chamber is of helical formation surrounded throughout its length by an enveloping jacket suitable for the preheating of the combustion air. As shown in Fig. 1 the combustion chamber 2 is of helical form, the surrounding air preheater jacket 5 being so arranged that air entering at 7 is fed to the chamber at its inlet through the ports 6. In the modification (Fig. 4) the walls of the chamber are formed by a tube bundle wound around a cone.

Title: Process for expelling the gases from metal bodies, especially anodes and surface electrodes in electrical discharge tubes
IPC: H01J9/385
Filed: 1920-07-12
Abstract: 149,238. Huth Ges., E. F., (Assignees of Bischoff, L., and Loewe, S.). Feb. 21, 1917, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-The expulsion of occluded gas from the anodes and other electrodes of thermionic values and R÷ntgenray tubes by passing a current therethrough, is facilitated by subdividing the anodes &c. to increase their resistance. The anode may consist of a plate a, Fig. 3, with slits cut alternately from either side. The slits may be formed into V- shaped slots by pulling out the ends of the plate, which mav be also hammered, drawn, and rolled to a cylindrical or other curved shape. In another arrangement, the anode consists of a number of strips connected at the ends. During the heating-process the anode grid h and cathode k may be connected in series as shown, or the grid and cathode in parallel may be connected in series with the anode. The heat radiated from the electrodes may also serve to expel gas from the glass parts of the valve &c., this operation being assisted by enclosing the valve &c. in a heat-insulating cover. The electrodes may also be heated before insertion in the valve. Eddy currents may be induced in the electrodes by means of a high-frequency alternating field. The grid may consist of a doubly-wound flat spiral the turns of which are spaced by glass supports fused thereon. In the arrangement shown in Fig. 5, the anode 14 is heated by a separate incandescent filament 15. In another arrangement, several filaments are arranged for connexion in parallel to expel gas. One of the filaments serves as the cathode during working, the others acting as spaces.

Abstract: 380,888. Lace machine jacquards. GOODLEY, H., 27, Central Avenue, Nottingham. July 23, 1931, No. 21012. [Class 74 (i).] An electrically operated jacquard described as applied to a lace curtain machine comprises spring pins 3 each connected electrically to solenoids 12 and each capable of making contact with a copper face-plate 2 of a cylinder 1, thereby completing a circuit, when permitted to do so by the pattern card 4. Each solenoid when excited releases a notched bar 6 connected by a metallic element 7 to a jack or picker 8. There are two solenoids to each bar, so arranged that the bar can be entirely released or released momentarily and held again in half-way position. Pickers when entirely released are free to follow the movement of the usual picker cam. The unselected pickers are held entirely or partly out of range of the warp and spool threads, according as the corresponding solenoid is in engagement with the notch 13 or 14.

Title: Discharge and safety valve for gas balloons
IPC: B64B1/64
Filed: 1920-07-12
Abstract: 153,311. Luftfahrzeugbau Sch³tte- Lanz. Sept. 17, 1917, [Convention date]. Aerostats.-The movable part a, Fig. 3, of a gas valve for airships and balloons is guided by a single lever d having a wide bearing on the valve ring and pivoted to a vertical member b on the part a, and is loaded by a single spring c acting on the member b above the connexion to the lever d. The valve may be manually operated by a cord connected to an extension of the lever d above the valve, or by a connexion to a cord m which is normally kept slack by a tension spring l. According to the Specification as open to inspection under Sect. 91 (3) (a), means for looking the valve in its open position may be provided, the looking means being released by a pull on a second cord or by a second pull on the same cord. Or, in two modifications, the valve is opened by a spring when a cord is respectively pulled or slackened, and is closed by a pull on a second cord. Fig. 6 (Cancelled) shows the valve connected to a lever 7 normally held by a spring c against a projection n on a lever 5. A pin 6 on a lever 10 connected to the operating-cord engages the lever 7 when the cord is pulled and a pawl 2 turns a cam 3, 4 to enable a recess 8 on the lever 5 to engage the lever 7 and lock the valve in its open position. A second pull on the cord causes the cam 3, 4 to press back the lever 5 against a spring c, and the valve is unlocked. Fig. 5 (Cancelled) shows the modification in which the valve is opened by a compression spring c when a cord o is pulled to move a lever d against a spring c, and is closed by a pull on a cord p. By placing the o to the left of the lever d and replacing the compression spring c by a tension spring, opening of the valve is effected by slackening the cord o. This subject-matter does not appear in the Specification as accepted.

Title: Cyclic fluidized catalytic cracking process
IPC: B01J20/18
Filed: 1974-05-14
Abstract: 1459952 Cracking STANDARD OIL CO 14 May 1974 [23 May 1973] 21197/74 Heading C5E A hydrocarbon feedstock containing sulphur compounds is cracked in the presence of a regenerable fluidized catalyst which has a crystalline aluminosilicate component and has been impregnated with a compound or mixture of compounds of a metal of Group IIa and calcined, the deactivated catalyst is separated and regenerated by burning in a stream of gas containing oxygen. The presence of the Group IIa metal (as oxide) reduces the amount of sulphur oxides in gases from the regenerator; the sulphur held back (as sulphate) on the catalyst is reduced to sulphide in the next cracking step and evolved as H 2 S in the stripper. The preferred metal is magnesium. Suitable feeds include kerosines, gas oils, residuals and cycle oils. The crystalline aluminosilicate may be a natural or synthetic zeolite, ion-exchanged with rare earth, ammonium or hydrogen ions and may be combined with silica and alumina or with clay and alumina.

Title: Improvements in or relating to the manufacture of water gas from low grade anthracite fuel

Abstract: 373,480. Water gas generation. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Industries of America, Inc.; 715, Water Street, Bridgeport, Connecticut, U.S.A.) July 24, 1931, No. 21260. [Classes 51 (i), 55 (i), and 55 (ii).] In the production of water gas from waste anthracite coal, combustion of the fuel is arrested before a substantial amount of its ash content has fused. The partly consumed fuel is completely burnt in a boiler furnace to generate steam for the " run " in the generator. The generator 10 is blasted with air introduced at 13, the combustion products passing to the boiler unit 21. The duration of the blast is such that the temperature of the fuel bed does not rise above the fusing point of the ash but is high enough to produce water gas in the succeeding "run." A measuring valve 16 in the hopper pipe 15 is connected to the discharge conveyer 12, and as the partly-burnt fuel is fed to the stoker 19 of the boiler furnace fresh fuel is automatically fed into the generator: The furnace fuel may be supplemented by fresh fuel - introduced through a feed pipe 17 leading to the stoker 19 through a hopper 18.
