Patent GB-689126-A (GB)
Title: Improvements in apparatus for simultaneously producing steam and gas
IPC: F22B1/22
Filed: 1950-10-31
Abstract: 689,126. Steam generators. SOC. DE CONSTRUCTIONS MECANO-THERMIQUES C.O.M.E.T. Oct.31,1950 [Dec.2,1949], No. 26602/50. Class 123 (ii) [Also in Group XXIX] A steam generator comprises one or several hot gas passageways 1 receiving the hot gases from a boiler firebox 5 fired by burners 6 (not shown) each passageway 1 consisting of a ring of small diameter tubes 2 welded side by side to form the passageway and strengthened by support hoops 3 and 12. The water or other liquid flows inside each of the small tubes 2 from a larger ring of tubes 7 also welded together to form the wall of the firebox 5. The hot gases flowing from 5 to 1 may then flow through a superheater composed of similar ring of small superheater tubes 2a Fig. 3, to supply the superheat after which the gases may pass through an economiser of similar construction. The successive sections although welded together as at 10 may be unwelded at a thinner part 11 of the weld. Coupling bolts 9 allow inspection of the weld. The ring of tubes 2 flares out into a cone 8 where the individual tubes are jointed to the corresponding tubes 7 of the furnace 5. The tubes 7 then join up with other converging tubes 8a near the burners 6. The inside of the furnace 5 is under gaseous pressure or forced draft to counteract the pressure inside the tubes 7. The furnace 5 has a partial refractory lining 13. In Fig. 2 the water tubes 2 are arranged helically around a steam separator wall bored to form tubular ducts therein. Pressure control. A relay system Fig. 9 operating the fuel supply valve when the steam pressure rises beyond working pressure, and controlled stop valve 45 is arranged in the hot gas outlet. The pressure of the furnace gases at 36 and the steam tube pressure at 37 adjust a common piston rod 33 whereby an attached arm 38 moves piston valves 39 of a pressure oil relay supplied with pressure oil at 43 passing through pipes 40, 40a, 41, 41a to control the fuel supply valve 45. The relay oil flows out at 44 to return to the relay system. Balancing springs 48, 48a tend to keep the control arm 38 at position for normal working pressure. The thickness of the tubes of these boilers can be thinner than boilers where the tubes are not joined together and so do not strengthen each other. Further the pressure of the hot gases on the ring of tubes counteracts the bursting pressure inside each tube. Such possible thinness of tube facilitates heat transfer from the hot gases to the water. Two or more fluids may be circulated through separated groups of pipes 2 and such fluids may be heated to different pressures (through larger or smaller total exposed areas of tube) so that such boilers may supply different steam pressures.

Title: Improvements in or relating to the chlorination of paraffin wax
IPC: C10G73/38
Filed: 1936-10-01
Abstract: Paraffin wax is chlorinated by dispersing it in water or dilute aqueous alkali, e.g. caustic soda, and treating the dispersion with gaseous chlorine.  About 1-2 vols. of aqueous liquid per vol. of wax is sufficient.  Dispersion may be effected by melting the wax on the surface of the water and agitating violently.  The suspension is cooled while stirring, and the temperature preferably controlled during chlorination, so as not to exceed 30-40 DEG  C.  The chlorinated wax and aqueous liquid normally separate into two layers on standing.  In the case of products having a density approximately that of water, salting out can be employed or the product extracted with, e.g., benzene, petroleum ether or trichlorethylene.  In an example, a paraffin wax is dispersed in 1 1/2 times its volume of water and chlorinated at 25-30 DEG  C.  The product after treating with sodium carbonate solution and filtering through soda ash contained 23,2 per cent chlorine.

Title: Improvements in or relating to air-intake systems for engines of aircraft
Inventor: RICHTER GERHARD
IPC: F02C7/042
Filed: 1959-08-05
Abstract: 875,032. Air inlets for aircraft engines. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Aug. 5, 1959 [Aug. 13. 1958], No. 26720/59. Class 4. An aircraft comprises the combination of an engine air inlet orifice inclined downwardly with respect to the plane containing the longitudinal axis of the aircraft and at least one deflector surface disposed in front of the said orifice and so arranged as to deflect the air flow towards the axis of said orifice. Fig. 1 is a side elevation of an annular wing aircraft which flies at a high angle of incidence and is capable of vertical take-off with its longitudinal axis vertical, with subsequent translation into a normal flying attitude. Engine air intakes 3 are located at the sides of the fuselage 4 with their axes downwardly inclined at angle α to a plane XX parallel to the longitudinal axis of the aircraft. The lower part of the air intake wall is formed with a slot 6 through which air is aspirated to prevent flow separation on the lower inner surface. This arrangement enables the air intake to operate satisfactorily at angles of up to 30 degrees to the relative airflow, but since during translation from vertical to horizontal flight, it may operate at angles in excess of 30 degrees vanes 7 are provided forward of and above the air intake to deflect the ambient air ahead of the air intake substantially into alignment with its inclined axis. A pair of vanes 7 pivotally mounted on a common pivot 9 are guided and supported by rollers 13 and moved from the retracted dottedline positions shown in Fig. 6 to the full-line extended positions by means of a linkwork 12 operated by a jack 11. In a further embodiment the linkwork may be dispersed with and each vane operated by an individual jack.

Title: Improvements in or relating to electrical discharge lamps
IPC: H01J61/067
Filed: 1945-10-12
Abstract: 601,504. Discharge lamps. FREEDMAN, P., and CROMPTON PARKINSON, Ltd. Oct. 12, 1945, No. 26736. [Class 39 (i)] In an electric discharge lamp, at least one of the main electrodes is surrounded by at least one and preferably two auxiliary electrodes, which are so shaped and arranged that when the main electrode functions as a cathode, any disintegrated cathode material is to a large extent interrupted by the auxiliary electrode or electrodes and subsequently deposited on the cathode, and which provide an aperture for the discharge such that the passage of the discharge is not sensibly impeded. The aperture, or where the auxiliary electrode or electrodes are surrounded by a tubular insulating member, the aperture provided by the tubular member, subtends an angle at any point of the cathode which does not exceed a right angle. To ensure that the passage of the discharge is not sensibly impeded, the cross-section of the aperture is of the order of 4 per cent or more of the average cross-section of the main discharge through the lamp. In one form the coiled coil filament 5, Fig. 2, is surrounded by two trough-like auxiliary electrodes 8, 9 which have slightly inturned longitudinal edges. The edges of the auxiliary electrodes remote from the foot 2, may be inturned. A tubular insulating member 10 fits over the auxiliary electrodes and may be frictionally retained in position or by small projections engaging the adjacent end edges of the auxiliary electrodes. The auxiliary electrodes may be coaxial cylinders 11, 12, Fig. 3, with inturned edges. In another embodiment, one of the electrodes 15, Fig. 4, forms a trough and the other a cylinder 16 fitting snugly in the tubular insulating member 10. The cylinder 16 may be a metallic coating. In a further embodiment, Fig. 5 (not shown), the electrode 15 is a short cylinder coaxial with and surrounded by the cylinder 16. The tubular member 10 may be coated with or composed of material, such as alumina, magnesia, silica, silicates, borates, tungstates or hard glass. The tubular member may be wholly or partly closed at one end and may, in the embodiments incorporating a cylindrical auxiliary electrode, be replaced by two tubular members of vitreous material fused to the outer edges of the auxiliary electrode, the whole then forming a single cylindrical structure. The exterior of the cylindrical electrode is coated with material such as alumina. Alternatively the cylindrical electrode may be prolonged at both ends, where' it is coated both internally and externally with material such as alumina or with fluorescent material. In a cold starting lamp a single auxiliary cylindrical electrode may be used. Preferable dimensions for de-spacing of the auxiliary electrodes are given in the Specification. Specifications 219,395, 313,726, [both in Class 39 (i)], 354,452, 395,804 and 449,031 are referred to.

Catalytically active elements or radicals are chemically combined in or with the zeolite. The silicate component may be an alkali metal silicate or a silicate soluble in alkali and may be partly replaced by alkaline salts of acids of the elements sulphur, nitrogen, tin, arsenic or antimony. The metallate component may be a soluble alkali metal compound of aluminium, chromium, zinc, vanadium, beryllium, tin, palladium, platinum, titanium, lead, tungsten, boron, molybdenum, uranium, tantalum, copper, nickel, iron, cobalt, silver, cadmium, manganese, zirconium, thorium or cerium or a complex compound of these metals formed with ammonia, hydrocyanic acid, sulphocyanic acid, oxalic acid, formic acid, tartaric acid. citric acid, glycerine or sugars. The metal salt may be a water soluble salt of the elements, copper, silver, gold, beryllium, zinc, cadmium, aluminium, rare earths, titanium, zirconium, tin, lead, thorium, chromium, uranium:, vanadium, manganese, iron, nickel, and cobalt. Alkali-metal cations in the zeolite may be replaced by the cations, ammonium, copper, silver, gold, beryllium, magnesium, calcium, zinc, strontium, cadmium, barium, aluminium, titanium, zirconium, tin, thorium, vanadium, chromium, uranium, manganese, iron, cobalt, nickel, palladium, platinum, or complex ions containing them. The base-exchange bodies mav be treated to form salt-like bodies with acids or salts of the elements, vanadium, tungsten, uranium, chromium, molybdenum, manganese, arsenic, sulphur, or chlorine, or with poly acids, peracids or compounds containing complex ions such as ferro-, ferri, sulpho- or metal-cyanogen compounds, ammonium complexes &c. The zeolites may be diluted during or after formation with kieselguhr, glaucosil, cellite, silicates, inactive zeolites, pumice &c. or may be coated onto massive fragments. The porosity of the products may be increased by incorporating substances which may be subsequently removed by leaching, volatilization or combustion. The hardness of the product may be increased by washing with a water glass solution. The zeolites may be mixed with compounds of the alkali metals, alkaline earth metals or strongly basic earth metals in order to stabilize or slow down the catalytic action, and with substances referred to as stabilizer promoters and consisting of compounds of heavy metals which are not catalysts for the oxidation of sulphur dioxide. When metals other than those of the platinum group are made use of as catalysts, it is unnecessary to submit the reaction gases to purification other than for the removal of dust.
