Abstract: 762,561. Aircraft folding noses. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G. July 8, 1955 [Nov. 19, 1954], No. 33510/54. Class 4. An aircraft has a foldable nose portion 10 hinged to the body 11 of the aircraft by at least two V-shaped hinge members one, 13, being smaller than the other, 12, and being pivoted to the body closer to the adjacent side thereof and closer to the line of separation of nose and body, than the other, so that when the larger member 12 pivots through 90 degrees the smaller member will cause the nose to pivot through a further 90 degrees. In Fig. 2, two members 12 (one not shown) are pivoted to the body on vertically aligned pivots 14, and to the nose on vertically aligned pivots 27. The smaller member 13 is pivoted to the body at 26 and to the nose at 28, being located between the two members 12. The location of these pivots is such that when the members 12 are pivoted through 90 degrees about pivot 14, by one or more jacks 20, the member 13  constrains the nose to rotate through 90 degrees about pivot 27 relative to the members 12, the nose thus assuming the position shown in chain lines, lying back against the side of the body. Bolts, preferably hydraulically actuated in sequence with the jack 20, are provided at the side of the fuselage remote from the hinges, and also in the plane of symmetry of the body, to secure the nose in the closed position. In this position the pivots 27 engage notches in members 16 extending forwardly from the body, to take up longitudinal stresses.

Title: Process for the direct preparation of pure sulphuric anhydride from pyrites
IPC: C01B17/69
Filed: 1947-12-23
Abstract: In a process for making sulphur trioxide from pyrites, the latter is mixed with an oxide of manganese, preferably in the form of a mineral such as braunite or polianite, and heated to at least 700 DEG  C.  In operation, the mixture is first heated to about 400 DEG  C., this temperature being maintained so long as gaseous impurities (oxides of As and Sb) are evolved and entrained by means of a current of air, which is passed through the furnace, into collecting receivers connected to the furnace, whereafter the receivers are replaced by sulphuric acid containers and the temperature is raised to at least 700 DEG  C. whereby SO3 is evolved and absorbed by the H2SO4.  The process may be operated either in a continuous batchwise manner, the residue from each batch being allowed to cool before adding the next batch, or in a discontinuous batch-wise manner, the residue in either case being used as the manganese oxide for succeeding batches. Auriferous pyrites may be treated in a similar manner and the gold may be extracted from the residue in known manner after magnetic extraction of the iron oxide.ALSO:In a process for making sulphur trioxide from auriferous pyrites (see Group III), the pyrites is mixed with an oxide of manganese, preferably in the form of a mineral such as braunite or polianite, and heated first to 400 DEG C, this temperature being maintained so long as gaseous impurities (oxides of As and Sb) are evolved and entrained by means of a current of air passing through the furnace into collecting receivers connected to the furnace, whereafter the receivers are replaced by sulphuric acid containers and the temperature is raised to at least 700 DEG C whereby SO3 is evolved and absorbed by the H2SO4.  Gold may then be extracted from the residue, the porous structure of which allows easy chlorination or cyanidation and washing.

Title: Iron ore reducing process and apparatus, using nuclear heat
IPC: G21D9/00
Filed: 1965-08-11
Abstract: <PICT:1109652/C6-C7/1> Iron ores are reduced with solid, liquid or gaseous reducing agents, e.g. coal, coke, anthracite, charcoal, petroleum oil, CO and/or H2 or natural gas, preferably in a continuous shaft kiln, by transferring the heat evolved in a nuclear reactor from a coolant circulating therethrough to the reaction material, preferably a pelletized fine-grained mixture of iron ore e.g. haematite and coal or coke.  A secondary heating vehicle, such as liquid metal or alloy e.g. Na or Na-K or a circulating gas mixture of CO and CO2 may be used to heat the mixture.  The reaction material may be fluidized in the reduction chamber by agitation, the reaction gas evolved or the injection of an auxiliary gas such as a CO/CO2 mixture. As shown, the reduction may be performed in two stages: partial reduction of briquettes of ore and coal, prepared in system 11 and pre-heated in chamber 13, to reduction levels in which 40-75% of the oxygen is removed in an ore/coal reactor 14, then final reduction by reducing gases such as CO and H2 to remove 85-95% of the oxygen in the untreated ore in an ore/gas reactor 15, both reactors being heated by a fluid heating medium circulating in a circuit 5 through a heat exchanger 2 heated by the nuclear reactor coolant in a circuit 4. The resulting sponge iron may be cooled in a cooling chamber 16 to yield heat in countercurrent to a fresh charge of briquettes by means of a circuit 17 in which may circulate liquid Pb or Na or alloys thereof, or CO2.  Excess coal (22) may be removed from the sponge iron (21) in a magnetic separator 19 and from ash (23) in an electrostatic separator 20 and returned to fresh ore (24). Gases evolved in the first reduction stage in reactor 14 may be removed, have their CO2 and H2O contents removed during cooling and cleaning in systems 26-28, and be returned pre-heated (through heat exchanger 26) to the reactor 15.
Patent GB-401121-A (GB)
Title: Improvements in and relating to process and apparatus for the production of nitrates
IPC: C01D9/06
Filed: 1932-12-05
Abstract: A process for the production of a nitrate by treatment of a nitrite with a gas containing nitrogen tetroxide is characterized by treating the nitrite in solution with a plurality of portions p  of the gas, said portions being separately introduced into the solution in successive stages, so that in each stage the nitrite solution is contacted with a different portion of the fresh gas. As liquors from which the nitrite is obtained, milk of lime or liquors containing basic alkali compounds such as sodium or potassium hydroxide or carbonate are specified.  The process applied to the production of sodium nitrate is as follows. Nitrogen oxide gases are cooled say to 30 DEG  C. in chamber 1 by contact with dilute nitric acid circulating therethrough.  The chamber may be of chrome iron and contains packing material 63. Oxidation to the extent of say 80 per cent or more occurs in this chamber.  The gases are divided into a plurality of portions, each passing through one of the coke-packed towers 6a-f wherein they react with the nitrite solution.  The merged exit gases pass to absorption towers 8, 9.  Sodium carbonate solution from 12 is circulated through tower 9, finally passing to tower 8. The liquor is pumped via cooler 68 through this tower and then passes to the towers 6f-a.  About 15--20 per cent of the nitrogen in this liquor may be present as nitrate, although in some cases the nitrate-nitrite ratio may be unity.  Oxidation air is supplied at 15. The towers 8, 9 may be of iron <PICT:0401121/III/1> and contain packing material 14, preferably ceramic rings.  The temperature of the liquid in the towers is below about 40 DEG  C.  The liquor passes through the towers 6f-a, being circulated through each and maintained below about 40 DEG  C.  That discharged from the last tower contains nitric acid and nitrogen oxides, the latter being removed by air in tower 53.  The liquor is then neutralized in tank 58 with sodium carbonate solution, and concentrated in a multiple effect evaporator 61, the solid being removed by filtration at 64.  Mother liquor from the filter is returned to the evaporator.  To prevent accumulation of sodium carbonate and nitrite in the solution, a portion of the returning liquor is passed to the liquor passing through towers 6f-a. Alternatively, part of the liquor from the last effect of the evaporator is so returned.  The number of absorption towers is not necessarily that shown.  The solution and gases may pass in countercurrent through tower 9.  The tower 1 may in some instances be omitted, or be replaced by separate cooling and oxidation plants.
