Title: Improvements in production of titanium dioxide
IPC: C22B34/12
Filed: 1950-02-20
Abstract: Following the sulphuric acid digestion of titaniferous material, especially slags, containing more than 1 per cent of the titanium having a valency less than four, wherein the material is heated with concentrated sulphuric acid to initiate the reaction, and the reaction mixture is permitted to set as a porous mass, e.g. as disclosed in Specification 288,569, [Class 1(iii)], oxygen-containing gas, e.g. air and/or oxygen, is passed through the mass whilst it is maintained at an elevated temperature sufficient to promote oxidation of the reduced titanium.  The solution obtained on leaching may contain 1-1.5 grms/litre trivalent titanium for the subsequent hydrolysis operation, and if all of the trivalent titanium is oxidized by the gas, the proper content may be restored by the addition of metallic iron or zinc to the solution.  Alternatively, if the oxidation by the gas is inadequate, it may be completed by blowing air through the solution, or by the use of hydrogen peroxide &c.  The temperature of the porous mass should be maintained at 150-260 DEG C. during oxidation, e.g. by the use of a heating jacket or coils, or external electrical space heaters. Heating by passage of steam (see Specification 671,728) is disclaimed.

[Class 130.] Transferring mechanism from a scrap-bunch forming device 94 to an intermittently rotating turret 81 having shaping pockets with removable covers 80 comprises pivoted arms 15 the resilient jaws of which receive bunches from the device 94 and carry them to one of the arms 45 of a member swinging about the shaft 43. The bunch is centred and its ends pointed, after which lifters raise it into the concave recess on the underside of arm 45 wherein it is retained by friction. The second arm 46 at right-angles to arm 45, meanwhile lies over a turret cover 80. The shaft 43 rises, releasing a roller 92 from cam 49 and allowing the arm 46 and cover 80 to become locked owing to the action of a spring 86 causing projections from a slide 84 to engage the cover. By a pin-and-slot connection between a lever 60 and the bracket carrying the arms 45, 46 the latter are swung through a right-angle, removing the turret cover and arms 46 and bringing the arm 45 and enclosed bunch into its place. As the shaft 43 descends the cam 49 engages a roller 77 which through a lever 74 depresses a yoke 71 carrying pins which eject the bunch into the turret-pocket. The shaft 43 again ascends, clearing the ejecting pins, and when in its top-most position the arms are swung back. As shaft 43 finally falls the cover 80 is replaced, and the cam 49 re-engages roller 92 and unlocks the arm 46 from the cover. The bunch lifters 28 have already been lowered, the centring members drawn back, and the arms 15 returned to their position adjacent to the rolling table 94.
