Title: Improvements in or relating to process of burning fuel oil and apparatus therefor
IPC: F23D11/10
Filed: 1923-05-15
Abstract: 216,325. Wiederwax, R. W. May 15, 1923. Vapour burners; vaporizing- apparatus.-Liquid fuel is heated to a temperature below its vaporizing point and is then delivered to a burner pipe in which it is heated suddenly to above its vaporizing point and mixed with aeriform fluid such as hot air or superheated steam before being discharged into the furnace in which it is burnt. Fig. 1 shows a burner apparatus in which a cylindrical shell 2 secured to the furnace wall is surrounded bv annular chambers 5, through which the air or steam and oil respectively pass on their way to a main burner discharging into the furnace and an auxiliary burner discharging into the shell. The main burner as shown in Fig. 2 comprises a fitting 21, a burner pipe 19, a nozzle 28 and a jet pipe 22. Steam or air heated to 900‹ F. or more by the auxiliary burner in the chamber 5 passes through a pipe 13 and a valve casing 16 to the jet pipe 22. The oil heated to just below vaporizing point in the chamber 7 passes through a pipe 15 and valve casing 24 to the fitting 21 and issuing through an aperture 27 is suddenly heated under reduced pressure to above its vaporizing point by contact with the pipe 22. The heated fuel then mixes with the steam or air issuing from the pipe 22 and is completely vaporized or gasefied before being discharged through the nozzle 28. The auxiliary burner is of similar construction to the main burner.
Patent GB-762138-A (GB)
Title: Improvements in or relating to processes for the preparation of hydracrylic esters
IPC: C07C69/675
Filed: 1954-05-04
Abstract: Hydracrylic esters are obtained by reacting carbon monoxide with ethylene oxide at between 60 DEG  and 100 DEG  C. under raised pressure and in the presence of water, a cobalt carbonylation catalyst, and if desired an alcohol.  Small amounts of phenolic compounds, e.g. hydroquinone, may be included in the reaction mixture to increase the velocity of the reaction.  Specified alcohols which may be present are methanol, ethanol and ethylene glycol and when these alcohols are present the corresponding hydracrylic esters are obtained in addition to the ethylene glycol monohydracrylate which is formed from the carbon monoxide, ethylene oxide and water.  Specified cobalt catalysts are cobalt carbonyl hydride and reduced cobalt deposited on a support such as kieselguhr.  The reaction is preferably carried out at 70-75 DEG  C. and at a pressure of 100 to 200 kilograms per square centimetre. The ethylene glycol monohydracrylate may be trans-esterified to form other hydracrylates, e.g. the methyl and ethyl hydracrylates. In examples for the production of ethylene glycol mono-hydracrylate: (1) ethylene oxide is reacted in an autoclave with carbon monoxide in the presence of water, the catalyst being reduced cobalt on kieselguhr; (2) as in (1) except that a small amount of hydroquinone is also present; (3) as in (2) except that the catalyst is first formed in the autoclave by depositing cobalt carbonate on kieselguhr and treating with carbon monoxide and water (see Group III), some cobalt hydracrylate is also formed in the main reaction; (4) as in (3) except that glycol is also present.  The hydracrylic esters may be converted to hydracrylamide by the action of ammonia and the amide may be dehydrated to form acrylamide which may be converted by further dehydration into acrylonitrile.  Alternatively, the two dehydrations may be effected in a single stage by passing hydracrylamide over a catalyst of the active alumina type at about 300 DEG  C.  The esters may also be dehydrated to form the corresponding acrylates by passing them over an active alumina catalyst at a suitable temperature, thus ethyl hydracrylate may be converted to ethyl acrylate in this way.ALSO:Cobalt carbonyl hydride which may be used as a catalyst in the reaction of carbon monoxide with ethylene oxide and water to form hydracrylic esters (see Group IV(b)) may be obtained by the action of carbon monoxide on cobalt or its salts in the presence of water.  In an example it is obtained by heating a mixture of water and cobalt carbonate deposited on kieselguhr in an autoclave at 100 DEG C. with carbon monoxide at a pressure of 90 kilograms per square centimetre.

Title: Improvements in or relating to sliver roll-forming machines
IPC: D01G15/62
Filed: 1944-07-11
Abstract: 590,332. Sliver-balling apparatus. FRASER & SONS Ltd., D., and FRASER, G. S. July 11, 1944, No. 13225. [Class 120 (i)] [Also in Group XXIX] A sliver rollforming machine has two endwise withdrawable half-arbors 20, 21, Fig. 1, to support the roll during formation and which are attached to a bifurcated carriage 17 vertically slidable between pairs of pillars 11, 12 and bearing at its upper end a piston rod and a piston 47 movable in a cylinder 15. The cylinder 15 is connected to an overhead reservoir through control valves actuated by a striker bracket 63 on the carriage 17 which rises as the diameter of the roll increases to a predetermined size, whereupon the arbors 20, 21 are withdrawn from the roll and the carriage 17 descends to force the roll from the machine. The roll is initially rotated by friction discs 24, 22 and 25, 23 driving the arbors 20, 21, but when the discs are lifted out of contact the drive is then by direct frictional contact of the sliver roll with a builder roller 28. When the roll attains a predetermined size the striker bracket 63 moves an adjustable stop 66 on a rod 62, Fig. 1, which allows a lever 56 first to release a valve 68, Fig. 3, to relieve the pressure in the cylinder 15, so that the arbors may be readily withdrawn, and then to release a valve 54 to allow a flow of fluid, preferably oil, into the cylinder 15 when the arbors have been withdrawn. Withdrawal of the arbors is effected when triggers 41, 42, Fig. 1, are pressed against adjustable stops 39, 40 by the rising carriage 17 to release bell-crank levers 31, 32 and compression springs 37, 38 which force the arbors apart so that the roll is free to "walkout" of the machine under the combined action of the rotating roller 28 and an angularly adjustable plate 45 on the descending carriage 17. As the carriage 17 approaches its lower 'position the bracket 63 moves a rod 74 to close a valve to restrict the flow of fluid from the lower end of the cylinder 15 to the reservoir thus providing a damping action.

Abstract: 406,002. Spray carburetters; centrifugal fans. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. May 7, 1932, No. 13229. Convention date, May 8, 1931. [Classes 7 (ii) and 7 (iii).] A sharp edge is provided on a surface near the discharge outlet of a rotating combustible mixture blower so that fuel deposited on the surface is projected from the edge and redistributed in the mixture stream. As shown in Fig. 1, a wall 7 of the blower casing is provided with a projecting surface 41 on which the unvaporized fuel is deposited and flows to an edge 31 from which it is blown off by eddies set up in an annular recess 33. A second projecting surface 51, edge 47 and recess 49 may be provided where the passage 29 enters a discharge chamber 11. The fuel is supplied to the air pipe 3 from a nozzle 17 by a pump 23 which is driven from the engine through a shaft 25 enclosed in a sheath 27. As shown in Fig. 4, the sheath is streamlined and provided with sharp edges 57 and incurved recesses 59 to redistribute any fuel deposited on it. In a modified construction, shown in Fig. 5, the fuel is deposited on a plate 61 carried by the blower blades 63 and is projected from a bevelled edge 65 of the plate, by eddies set up in an annular recess 73. The stationary edges described with reference to Fig. 1 may also be used in combination with this construction. An annular chamber 75 with a discharge edge redistributes the fuel deposited on the rotor surface 79. The edges 81 of the blades are curved to lead the fuel towards the edge 65. The mixture is formed by drawing air through a tube 83 over a fuel nozzle 85, and discharging the rich mixture produced, into the air passage 5, through rotating nozzles 91, formed in a shroud 87 carried by the blower. A conical ring 97 in the passage 83 causes the rich mixture to be distributed over a flat surface 95 of the shroud 87.

Title: Pressure control means applicable to pressurized aircraft cabins
IPC: B64D13/02
Filed: 1951-06-07
Abstract: 696,559. Fluid-pressure servomotor-control systems. GARRETT CORPORATION. June 7, 1951 [June 17, 1950], No. 13506/51. Class 135 An outlet valve 15 from a pressurized enclosure is controlled by pilot valve members 58, 95 so that, in the case of a pressurized aircraft cabin, the cabin pressure is maintained substantially equal to atmospheric pressure up to a first predetermined altitude, is maintained at a constant value between the first and a second altitude, is regulated to a constant differential with respect to atmospheric pressure between the second and a third altitude, and thereafter is so adjusted that a constant ratio is maintained between cabin pressure less a constant and atmospheric pressure less that constant. The constant may be zero or it may have, e.g., the value of the partial pressure of water vapour in the human lungs so that in the event of'rupture of the cabin, the maximum safe ratio between the partial pressures, of air in the lungs of an occupant before and after decompression is not exceeded. Up to the first altitude, a control pressure chamber 31 above a diaphragm 25 which actuates the valve 15 is vented to atmosphere, through passages 46, 64, 51, 52, by the valve member 58 which is adjusted by an evacuated bellows 55 subject to cabin pressure. Since the chamber 31 has a restricted connection 40, and a chamber 30 below the diaphragm an unrestricted connection 39, with the cabin interior, whilst a depression is maintained in a chamber 21 above the valve due to openings 23 to a restricted part of the cabin outflow duct, the cabin pressure will remain substantially as atmospheric until the valve member 58 starts to throttle the vent from the chamber 31. The cabin pressure will then remain constant until, at the second altitude, the valve member 95, which is actuated by a diaphragm 84 exposed on its upper and lower surfaces to cabin and atmospheric pressures respectively, opens to control the vent from the chamber 31 to maintain a constant difference between cabin and atmospheric pressures. At the third altitude, an evacuated, spring-loaded, bellows 88 will have expanded sufficiently to engage the diaphragm 84 to cause the valve 15 to be controlled to maintain a constant ratio between cabin and atmospheric pressures each diminished by a constant. The pilot valve members 58, 95 have moving seats 62, 97 connected by a lever 71, pivoted at 75, to the diaphragm so as to give a " feedback action to avoid hunting. Specifications 648,002 and 655,601 are referred to.

Abstract: 600,659. Resin treated fibre boards. CAMPBELL, R. C., and CAMPBELL, D. July 15, 1944, No. 13566. [Class 96] Fibre boards for building or floor covering, &c., are treated on one or both sides and if desired the edges with a diluted solution of a thermosetting synthetic resin, and then with a stronger solution thereof, dried and heat treated under pressure to polymerise the resin. Cresol formaldehyde resin with methylated spirit as solvent may be used and may be applied to the board by means of a brush or roller. Drying is conducted at a temperature insufficient to cure the resin and when dry the boards are reduced in thickness during the curing process by use of a heated platen press or by passage between pressure rollers in a heated chamber. In the drawing the board 1 is coated by roller 2 with resin solution 3 and dried in chamber 5 while supported by belt 6, heat being applied by electric elements 7. Upper and lower pressure plates 8 and 9, either in succession or as endless bands are then applied to the board and it is passed into the chamber 10, pressed between rollers 12 and 13 and subjected to heat from elements 11. The distance between successive pairs of rollers may be reduced, or the loading on them increased as the board proceeds through the chamber. A decorative finish may be obtained by the use of dyes. Specification 550,504 is referred to.

Abstract: 234,810. Kremenezky, J. [Firm of], and Wimberger, L. May 23, 1924, [Convention date]. Electrical systems, automatic. - In an automatic electrical system, the ends of the sections of track are defined by high resistances 3, connected across the track rails 1, 2, and these rails, at the middle of the section, are connected to the coil 4 which controls the signals w, r. The Figure shows the controlling coil 4 arranged as the secondary of a transformer, the primary 5 of which is supplied from the line-wires 6 and is movable on guides and rollers along the core 7 so as to be moved away from the core 4 when the current therein is increased by a train on the section shunting the resistances 3. The arm 8 then acts to close the contact in the circuit of the danger lamp r at the entrance of the occupied section. When the section is cleared the coil 7 returns and the clear signal lamp w is energized. The lamps are supplied through a transformer 13, and are preferably illuminated intermittently by means of a solenoid 16 having a core 17 dipping into mercury. As an alternative to the relay construction described above the contacts in the lamp circuits may be operated by an electromagnet or solenoid supplied from the secondary of a transformer or otherwise. The Specification as open to inspection under Sect. 91 (3) (a) states that alternatively, the track rails may be divided into sections by gaps bridged bv throttling coils comprising oppositely wound coils on a core, when direct current is used for traction purposes on the track. This subject-matter does not appear in the Specification as accepted.
