Title: A method for the recovery of hydrogen fluoride from spent gases
Inventor: YAMAGUCHI TARO
IPC: C01B33/10
Filed: 1963-01-14
Abstract: Hydrogen fluoride may be recovered from a mixture of gases containing gaseous hydrogen fluoride, and optionally in addition silicon fluoride (SiF4), by (I) contacting the mixture with a neutral or acidic solution at from 10 DEG  C. to 90 DEG  C., comprising at least one of sodium sulphate, sodium chloride, sodium nitrate, potassium sulphate, potassium chloride, potassium nitrate, ammonium sulphate, ammonium chloride and ammonium nitrate, to form an aqueous solution comprising at least one of sodium hydrogen fluoride, potassium hydrogen fluoride and ammonium hydrogen fluoride and, when SiF4 is present, additionally sodium silicon fluoride, potassium silicon fluoride and ammonium silicon fluoride, the amount of HF contacted being insufficient to cause precipitation of any KHF2 or NH4HF2, and when SiF4 is present, any ammonium silicon fluoride; (II) adding sodium fluoride to the aqueous solution to precipitate sodium hydrogen fluoride and recovering said precipitate; and (III) heating the precipitate to convert it to sodium fluoride and gaseous hydrogen fluoride as product, and when SiF4 is present, the temperature of heating being less than that at which Na2SiF6 or K2SiF6 decompose. Advantageously, the solution is filtered between stages (I) and (II). When both HF and SiF4 are present, the initial solution of stage (I) preferably contains one or more of the chlorides, nitrates and sulphates of potassium and ammonium, but is preferably free from sodium chloride, nitrate or sulphate. Also, an alkaline-reacting potassium compound may be added after stage (I) to precipitate the silicofluoride as K2SiF6, which is filtered off before stage (II). The sodium fluoride produced by the thermal decomposition of stage (III) may be recycled to stage (II) to bring about further precipitation of sodium hydrogen fluoride.  The solution remaining after the precipitation of stage (II) may be recycled to stage (I) for further absorption of gas.

Title: Improvements in or relating to aircraft power plant
Inventor: JACKSON ALFRED DENNIS
IPC: B64C23/00
Filed: 1961-01-14
Abstract: 920,956. Controlling aircraft. ROLLSROYCE Ltd. Nov. 27, 1961 [Jan. 14, 1961], No. 1630/61. Class 4. An aircraft includes one or more forward propulsion engines, at least one of said engines being arranged to drive through a clutch device an auxiliary compressor which supplies compressed air to ducting leading to control surfaces of the aircraft, said compressed air being discharged to atmosphere over control surfaces in order to prevent break-away of the normal atmospheric airflow over said surfaces. A wing 11 houses an underslung nacelle 19 for a turbo-propeller power plant 10 having high and low pressure turbines, the low pressure turbine being adapted to drive, through a shaft 20 and clutch 21, an axial flow compressor 23 provided at its front end with an air intake 23a. The delivery end of the compressor is connected to a conduit 24 via a part spherical coupling 25, the conduit housing a pivoted flap valve (not shown) and being connected to a transverse conduit 27 which is provided with connections 29 to a gap 30 formed between the downstream edge 11a of the wing 11 and the upstream edge 31a of a flap 31. The air intake 23a of the compressor draws air either through louvres 32 in the wall of the nacelle or through apertures in the surface of the wing to enable the boundary layer air to be drawn off. When the flaps are set to the dotted line position of Fig. 2 to produce a high degree of lift clutch 21 is engaged to drive compressor 23 and the valve in conduit 24 is opened in order to supply a flow of air over the surface of the flap to prevent breakaway of the normal ambient airflow. When more than one compressor 23 supplies air to conduit 27 the valves in the respective conduits 24 prevent surging due to one compressor being started before the other, and if one compressor fails in operation the valve prevents back-flow from conduit 27. A valve 33 may be provided in conduit 27 to be opened during starting of the compressors to prevent back-pressure. Specification 883,102 is referred to.

Title: Improvements in or relating to rotary wings for aircraft
IPC: B64C27/46
Filed: 1946-01-18
Abstract: 606,784. Rotary wing aircraft. FAIREY AVIATION CO., Ltd., and HODSON, C. F. Jan. 18, 1946, No. 1839. [Class 4] A rotary wing system has each blade divided transversely into at least an inner, or hub, section and an outer, or tip, section, the inner section being arranged for the reduction of its resistance to the airflow which, during the retreating travel of the blade, produces a downward reaction or reversed flow. Fig. 2 shows a construction in which the inner section 15 of the blade is slidable along the main spar 13 and can be telescoped over the fixed outer section 12. The section 15 is moved outwardly by the pilot when vibration or flapping of the blade occurs. In the arrangement according to Fig. 4 the outer and inner blade sections 16, 18 are adapted for cyclical pitch variations in opposite senses. The outer end of the inner section may be secured to the inner end of the outer section, and the pitch variation applied at the centre of the inner section, the pitch angle of the latter being thereby graduated along its length. Fig. 5 shows a modification in which the outer and inner sections 22, 26, and intermediate sections 27, 28 are interconnected by flexible rods 29, 30 to effect a progressive change of pitch between the inner and outer sections. The differential pitch adjustments of the blade sections are effected by separate concentric swashplates. Fig. 7 shows a construction of blade in which the ratio between the effective lengths of the inner and outer sections 41, 39 may be varied by coupling an intermediate section 42 to either section by means of bolts 46, 47 operated by a longitudinal member 45. To avoid the necessity of cyclical pitch change, the inner blade portion may be of an aerofoil section suitable for travel in either direction, e.g. a semiellipse or segment of a circle, and preferably having appreciable lift at zero incidence.

Title: Improvements in and relating to the Working of Combustion Turbines.

IPC: F02C7/08
Filed: 1916-02-08
Abstract: 100,072. Bischof, B. Feb. 8, 1915, [Convention date]. Working-fluid supply. -Relates to combustionproduct turbines wherein the charge is diluted by exhaust gases and is heated in a regenerator 5 by the exhaust gases on its way to the combustion chamber 1, the exhaust gases flowing through the regenerator in an opposite direction and parallel to the new charge, and consists in facilitating the transfer of heat in the regenerator by securing high-pressure conditions, i.e. by arranging that the gases from the combustion chamber do not expand in the nozzles 2 down to atmospheric pressure. After acting on the turbine wheel 3, the gases pass through the regenerator 5, and a portion equal in weight to the charge is led by a pipe 20 to the low-pressure chamber 22 for further action on the wheel 3. The rest of the exhaust gases may be led through a cooler 7 and returned to the regenerator 5 by a compressor delivering into a pipe 16, or conducted further to a regenerator 9, a cooler 11, and forced by a compressor 30 back through the regenerator 9 and so to the regenerator 5 by a pipe 35, where it mixes with compressed air supplied by a compressor 29, the mixture being heated in the regenerator 5 by the exhaust gases and then led to the combustion chamber 1, where it mixes with fuel blown in through a nozzle 28 for flameless surface combustion. The pipe 20 tapping the exhaust gases may be located at any point of the regenerator 5 or in front of the same. When gas is used instead of liquid fuel, it is compressed and regenerated separately before mixing in the combustion chamber. Specifications 2565/95 and 21,320/04 are referred to.
