Title: Improvements in or relating to titanium production
IPC: C22B34/12
Filed: 1958-01-27
Abstract: Ilmenite ore ground to 1/250 inch mesh is treated with sulphuric acid and heated to 80 DEG -120 DEG C. and the exothermic reaction produced results in caking of the product.  The solidified mass is then leached with dilute sulphuric acid or a mixture of sulphuric and hydrochloric acid giving an acid solution of iron and titanium which is then filtered and the iron removed from the filtrate by crystallisation at 5 DEG -15 DEG C.  The substantially iron-free solution is then treated with hydrogen chloride gas at -10 DEG C. to -20 DEG C. which removes the remaining iron as a precipitate of iron chloride which is removed by filtration.  Solid potassium chloride is added to the filtrate and the temperature reduced to 0 DEG  C. to precipitate potassium chlorotitanate.  The precipitate may be filtered off, dissolved in hydrochloric acid, and treated with hydrogen chloride gas to reprecipitate the potassium chlorotitanate. Specifications 838,822, 883,721 and U.S.A. Specifications 1,437,984 and 2,205,854 are referred to.ALSO:Titanium is produced by heating a mixture of a dried alkali metal chlorotitanate, containing not more than 0,01% of physically or chemically bound water, with an alkaline earth metal in an inert atmosphere at a temperature between 250 DEG C. and 600 DEG C. and separating the titanium from the other products of the reaction.  The inert atmosphere may be argon or helium or may be a vacuum and the titanium may be separated by leaching with dilute hydrochloric acid or by vacuum distillation.  The chlorotitanate may be formed from ilmenite, rutile, or a titanium bearing slag and after precipitation may be dissolved and reprecipitated to yield larger crystals and improve the quality of the titanium obtained.  The chlorotitanate and the alkaline earth metal may be ground to give a particle size of 1-10 microns and may be pelleted before reduction at 250 DEG C.-600 DEG C.  Specifications 838,822, 883,721 and U.S.A. 1,437,984 and 2,205,854 are referred to.

Abstract: 565,865. Actuation of switches. HUGHES, W. March 2, 1943, No. 3399. [Class 40 (i)] [Also in Groups XII and XXXVII] To ensure that an operation, e.g. the ejection of coke, shall take place only when two machines, e.g. the guide and pusher machines, associated with a battery of coke ovens are in appropriate relative positions, each machine is caused to send an electric impulse as it passes each oven to step a separate switch member, the switch being closed to permit the operation only when the positions of the two members correspond. As shown, the switch comprises contact members carried by a disc 25 and a contact operating member carried by a similar coaxial disc (not shown). The driving mechanism for each disc comprises an electric motor coupled by a centrifugal clutch and cords 34 to a bar 35 which carries pivoted driving pawls 37, 38 which co-operate with pins on the disc. The direction of rotation of the motors depends on the polarity of the impulse and this in turn depends on the direction of movement of the associated machine. A member 39 pivoted to the bar 35 and coupled by a pin-and-slot connection to the framework comes between two pins at each actuation and prevents overdrive.
