Title: Improvements in Elastic Fluid Turbines.
Inventor: MILLS CLAUDE KENNEDY
Filed: 1897-09-07
Granted: 1897-10-09
Abstract: 20,536. Mills, C. K., [Curtis, C. G.]. Sept. 7. Steam &c. turbines.-Relates to turbines of the type described in Specifications Nos. 19,246, 19,247, and 19,248, A.D. 1896, and comprises means for varying the volume of the elastic fluid jet without substantially varying its velocity, and also means whereby the turbine may be used either as a condensing or non- condensing engine. The volume of the jet is varied by moving the slide K, of which the edge e forms one side of the jet or nozzle. The different ratios of expansion required when the turbine is used as a condensing or non-condensing engine are obtained by adjusting the flexible wall g of the nozzle by the screw S, as shown in dotted lines, and by the use of two adjustable intermediate passages N, 0 between the turbine vanes A, B. When the turbine is running as a non - condensing engine the passage N is used ; when it is to be used for condensing work the passage 0 is used. The vanes of the passage O are spread out at their discharging - ends to deliver the fluid jet to a number of the vanes B greater than the number of the vanes A from which they receive the fluid, thereby giving the required additional expansion to the elastic fluid.

Title: Improvements in the Manufacture of Artificial Cryolite.
Filed: 1899-06-08
Granted: 1900-04-14
Abstract: 11,963. M a t t h e w s , D., and British Aluminium Co. June 8. Cryolite, artificial. - Fluor spar and sulphuric acid are placed in a lead still a, having a steam heating-jacket b, and an inlet pipe 4 for air for stirring the mixture. On heating, at first to 100‹ C., and for some hours afterwards to a higher temperature, hydrofluoric acid is evolved, and passes by the lead pipe d to a second similar still c for purifying the acid. This still is charged with potassium - fluoride solution, which absorbs the greater portion of the acid. When the reaction in the first still is finished, the two vessels are disconnected, and steam turned into the jacket f. Pure hydrofluoric acid passes over to an ebonitelined precipitating-vessel e, receiving a solution of sodium chloride from the tank g, and hydrate of alumina by the funnel e'. The amounts of sodium chloride and of alumina added are just sufficient for each to combine with one half the hydrofluoric acid. The whole is well stirred by air admitted by the pipe 6. The artificial cryolite separates out in a gelatinous state, while hydrochloric acid forms and is run off. The cryolite is led to an ebonite - lined washing-tank h, and thence to a vulcanite filter-press i, and is afterwards dried. Any vapours of hydrofluoric acid which escape by the pipe e' may be absorbed in vessels j by means of potassium carbonate, to form potassium fluoride for use in the vessel c.
