Title: Improvements in or relating to the recovery of titanium values
IPC: C22B34/12
Filed: 1950-02-02
Abstract: Titanium values are recovered from a slag containing at least 65 per cent TiO2 and 1-16 per cent iron expressed as FeO by comminuting the slag so that all particles are smaller than 74 microns in average diameter, whilst not more than about 30 per cent by weight are smaller than 10 microns, mixing with 85-98 per cent sulphuric acid in amount equivalent to 2-2.6 parts 100 per cent acid per part TiO2, and causing the acid and slag to react by heating to a temperature of 160-190 DEG C to initiate the reaction.  The slags may be produced by smelting, say, ilmenite with basic fluxing agents, e.g. calcium, magnesium or aluminium oxides, and separating the iron.  After the acid digestion the cake is cooled by air, and in order that only 1.5-2.5 per cent of the titanium is present in the titanous form, the blowing is continued during the addition of water in the presence of 0.2-2 per cent finely divided carbon based on the weight of the slag. The carbon, which acts catalytically, may be added as such, or a carbonaceous material such as starch, convertible by the acid to carbon, may be mixed with the slag.  The aqueous slurry (sp. qr. 1.4-1.55) is clarified by the addition 0.03-0.06 per cent animal glue, and a solution of 0.004-0.01 per cent antimony oxide in 10 per cent sodium sulphide solution, the amounts being reckoned on the weight of the slurry.  Hydrolysis of the solution is effected by standard methods, e.g. by boiling in the presence of an added alkali metal titanate nucleating agent, and the precipitate calcined to anatase or rutile.

In an hydrodynamic torque converter of the rotating casing 10 type, and including a ring of pump blades 12 in the outflow section, and respective first and second stage turbine blades 22, 18, and a ring of reaction guide blades 26, in the inflow section, the specific torque absorption (Ms) range, (as herein defined), is extended to cover a low range (40-80) and a high range (80-140), by replacing the actual blade components whilst maintaining the angle of deviation #, between the outlet angle of the blade and the optimum inlet flow angle to the blade, of the turbine and guide blades, within specified ranges. The Ms value is defined as the torque absorption of the blade system of the size accepted as the norm size 1-0 at an input speed of 1,700 r.p.m. at the shift point. The angle # of the first turbine stage blades for the low and high Ms ranges, respectively, lies within the ranges (50-90) and (75-115), and for the guide ring and second turbine ring, respectively, in both ranges, within (25-50) and (40-65). The reaction blades may be held against rotation in either direction, or allowed to rotate in either direction, or may act to deliver power when rotated in the same direction as the pump. The blades are die-cast with their supporting rings, the pump blades 12 and guide blades 26 then being riveted to their rings 14 and 28, respectively. The first turbine blades 22 are formed with integrally cast screws, and the second turbine blades 18 with a through-going screw, for their attachment to the ring 20. The aluminium hub 16a of the turbine is splined to a steel shaft 16, relative thermal expansion of the two materials being compensated for by making the diameters of the shaft and hub bear a relation to the strength of the materials and to the number of splines. The splines have radial sides, or sides parallel to radial planes, and their heights and widths are such that they are equally strong having regard to the strengths of the respective materials.
