Title: Process for obtaining alkali metal hydroxide solutions
Inventor: SHIRLEY MARCUS BERNARD
IPC: C01D1/04
Filed: 1956-09-17
Abstract: Alkali metal hydroxides, particularly lithium and sodium are recovered from aqueous solutions containing a carbonate, sulphite, bicarbonate or bisulphite by heating under super-atmospheric pressure, e.g. 250 to 1100 p.s.i.g., and bleeding off a portion of steam together with CO2 or SO2 which is formed by decomposition and recovering the residual alkali metal hydroxide.  About 10-40 per cent by weight of water is removed as steam.  Carbon dioxide or/and sulphur dioxide, e.g. from flue or tail gases, may be used to decompose solutions containing salts of weak acids such as mercaptides and borates which are then treated according to the invention.  Some sodium sulphate may be added to the solution to minimize caustic embrittlement but the process should be conducted in the absence of oxygen when sulphites are present to prevent sulphate being formed.  Caustic solutions containing lignins, from the Kraft process, are burnt in a furnace to give sodium carbonate for treatment by the process of the invention.  The Provisional Specification describes the treatment according to the invention of weak acids without retreatment with CO2 or SO2.

Patent GB-1049876-A (GB)
Title: Dual phase combustion process and apparatus for the production of inert gases
IPC: F02B3/06
Filed: 1963-07-19
Abstract: A gas mixture containing N2, CO2, H2O which is incapable of burning or supporting combustion is produced by operating an internal-combustion engine to produce exhaust gases containing in themselves sufficient free O2 to support combustion of a hydrocarbon fuel, mixing the exhaust gases with just sufficient hydrocarbon fuel to combine with all the free O2 therein, and igniting and burning the mixture in a secondary combustion chamber. The internal-combustion engine may be a diesel engine, a free piston engine or a gas turbine. As shown in Fig. 1, exhaust gases from a diesel engine PM containing sufficient free oxygen to support the secondary combustion are passed via tube 25 into tube 26 where it is sprayed with diesel fuel from nozzle 33, and the mixture is ignited in turbulence chamber 28 by ignition plug 34.  The diesel fuel flow is regulated by needle valve 31 so that all free oxygen is consumed and no excess hydrocarbon remains in the final product.  Damper 47 may be used to control the flow of diesel engine exhaust gases.  The ignited mixture passes through combustion tube 27 which is separated from tube 26 by inclined and straight vanes 50, 51 which mix the ignited mixture. The mixture passes out at duct 48 where it is sprayed with water from jets 55 which water bubbles the formed inert gases through outlets 52 in header 49.  The gases bubble up through the water pool, pass through water sprays from nozzle 61, through baffle filter 68 and emerge at outlet 72. <PICT:1049876/C1/1>

Title: Methods of and means for preparing refractories and refractory masses so produced
IPC: C04B33/24
Filed: 1933-10-18
Abstract: A ceramic mass adapted to be shaped and sintered to form a refractory consists of highly refractory materials in admixture with ignited zeolites or alternatively with ingredients adapted to react to form zeolites on heating.  In the latter case the mass may first be heated below the sintering temperature.  The zeolites employed are those corresponding to the formula X mol. SiO2, 1 mol. Al2O3, 1 mol. MeO, Y mol H2O, where MeO signifies the oxide of an alkali or alkaline earth metal, X is a definite whole number not greater than 5, and Y a number not necessarily whole.  SiO2 may be replaced by equivalent amounts of TiO2, and Al2O3 by equivalent amounts of Fe2O3 or Cr2O3. The proportion of zeolite present should be between 3 and 20 per cent. In an example 5 parts of magnesium chabazite, produced from naturally occurring sodium chabazite by base exchange, are sintered with 95 parts of corundum.  In another example kaolin is melted with quartz and alkali or alkaline earth metal carbonate to form a glass which is broken into granules and treated with water to extract sodium silicate, the residue forming zeolite by absorption of water. This is lightly calcined, and 8 parts are mixed with 92 of corundum and sintered.  In another example 62 parts of chalk are fused with 38 parts of aluminium oxide; 5 parts of the resulting glass are mixed with 85 parts of corundum, 2,2 parts of lithium carbonate and 7,8 parts of Shetland kaolin and sintered, the ingredients forming a zeolite which bonds the corundum.

Abstract: 305,072. Farrow, L., Boyce, J. C. H., and Farrow, W. T. Oct. 29, 1927. Working-fluid supply.-In a gas turbine, carburetted air is forced by a fan 12 through a channel formed by a volute plate 23, and through a perforated plate. 24 into a combustion chamber 27<b> from which the products pass over guide plates 28 to the blades 29 of a turbine 13. The turbine drives an electric generator 16, and its shaft 17 is fitted with a pulley. The fan 12 is separately driven by an electric motor 14. The generator and motor are connected to a storage battery by automatic switch-gear which causes the generator to act as a motor on starting. The generator may be connected directly to the motor 14 when the output is low, and the speed of the motor may be controlled. Combustion is started by a sparking plug 26 which is then cut out automatically. The petrol or other fuel, the supply of which may be controlled in accordance with the speed of the fan, is fed by a pipe 21 to absorbent material 20 surrounding perforated airintake pipes 19<a>.

Filed: 1974-06-28
Abstract: 1464890 Fuel injection pumps BENDIX CORP 28 June 1974 [28 June 1973] 28904/74 Heading F1A A fuel injection pump comprises a plurality of plungers 3, 3A, reciprocable in respective cylinders 4, 4A .... and a pair of electromagnetic spill  valves 32, 33 for each pair of cylinders, each having a first position connecting one of its cylinders to a spill passage and a second position connecting the other of its cylinders to a spill passage, whereby alternate changeover of each pair of valves causes delivery from an associated cylinder during the overlapping periods when the valves close both spill passages from a cylinder. The plungers are reciprocated by a cam-shaft 22 which drives a distributor 37 arranged to supply electrical pulses for operating solenoids 17, 23 which actuate the valves 32, 33. Each valve operates every 180 degrees of cam-shaft rotation, the phase relationships of the valve operations to the cam-shaft position determining the timing of injection and the quantity of fuel delivered. The valves 32, 33 are rotatable in a bore in the pump body 18 and include respective axial exhaust bores 13, 25 connected by respective passages 14-16 and 26-28 to a suction chamber 5, the latter being in communication with the cylinders 4, 4A ..... through ports (7) uncovered by the plunger 3, 3A..... during the filling strokes. During a pumping stroke of, e.g. the plunger 3, fuel initially displaced by the plunger 3 flows to the exhaust bore 13 through a passage 30 and slot 8 in the body 18 and an aligned slot 31 in the valve 32. Injection commences when energization of the solenoid 17 closes the slot 31 and continues until de-energization of the solenoid 23 causes alignment of slots 12 and 24 of the valve 33 whereby fuel is then displaced from the cylinder 4 through a passage 9-11 and the slots 12, 24 into the exhaust bore 25. The delivery from the cylinder 4A is controlled in an analogous manner under control of the slots 47, 48 and 52, 53 of the valves 32, 33 respectively.
