Title: Improvements in and relating to method of and means for softening water
IPC: C02F1/68
Filed: 1921-10-26
Abstract: 191,859. Wollaston, T. R. Oct. 26, 1921. Purifying liquids.-Apparatus for softening water comprises a plurality of treatment tanks A, B, and a tank C for making reagent solution, to all of which water is delivered from a main K through valves L which are opened by hand but closed automatically when the corresponding tank is full to the level of its overflow. The automatic device for the tank C is shown in Fig. 2. The overflow pipe F delivers into a deep and narrow container P suspended from one arm of a valve lever M on the other arm of which a weight N slides between stops O<1>, O<2>. When the valve is opened by hand, the weight N slides against the stop O<1>, and stays there until the container P is filled by the overflow and overbalances the lever, thus closing the valve. Each of the tanks is provided with a hand-operated paddle D and a sludge cock E. A sleeve G may be moved vertically on the overflow pipe F of the tank C so as to adjust the level of overflow therefrom. In operation, lime, soda, or other reagent. preferably in powdered or compressed form and made up in packages or lozenges containing the correct quantity, is supplied to the tank C, as the latter is filled from the main K. When clear solution has formed, the tank C is emptied into one of the treatment tanks which simultaneously is filled with water from the main. A definite amount of solution measured by the tank C is thus added to a definite amount of water measured by the treatment tank. According to the Provisional Specification, the solid reagents may be placed in a wire cage attached to a chain which passes over a wheel to one end of a. pivoted lever, the other end of which is connected to a container. The arrangement is such that the cake is dipped into the reagent tank when the latter is full, and is lifted again when the container is raised by movement of the lever operating the supply cock.
Patent GB-883311-A (GB)
Title: Improvements in and relating to the production of alumina
IPC: C01F7/26
Filed: 1959-08-19
Abstract: <PICT:0883311/III/1> Alumina is obtained from solutions produced by dissolving aluminium-containing materials, for example bauxite, in sulphuric acid by so adjusting the solution that the SO3 : Al2O3 weight ratio is less than 2,35 (which value corresponds to Al2(SO4)3), hydrolysing the adjusted solution at 180 DEG -300 DEG C. to precipitate a basic aluminium sulphate or hydrated alumina, and decomposing this precipitate to leave alumina.  The hydrolysis is preferably carried out under pressure.  The SO3 : Al2O3 weight ratio in the solution may be adjusted by dissolving aluminium metal in the solution, or by digesting the solution with a source of alumina, for example bauxite, preferably at 100 DEG C. to 140 DEG C., or by electrolysing the solution in a cell provided with a suitable membrane, for example a selective anion exchange membrane, paper, or parchment, thereby removing sulphate ions from the solution in the cathode compartment, or by adding to the solution, which may have been partially adjusted, some of the hydrolysis precipitate from a previous batch or a basic aluminium sulphate from any source.  In examples, crushed bauxite is digested with sulphuric acid under pressure in digestion stage 1.  If sufficient air or oxygen is provided, at least part of the sulphuric acid may be replaced by pyrite.  The liquor from stage 1 is passed to modification stage 2, where the SO3 : AL2O3 ratio is adjusted by any of the methods previously indicated.  Any iron in the solution may be reduced to the ferrous state by aluminium metal or other reducing agent.  The adjusted liquor is passed to precipitation stage 3, where it is maintained at 180 DEG -300 DEG C. to permit hydrolysis to take place. The precipitate is recovered, and part is recycled to stage 3 and the remainder is calcined in stage 4 to give alumina product and sulphur dioxide, which is passed to digestion stage 1.  The liquor from stage 3 is similarly recycled to stage 1.
