Patent GB-789497-A (GB)
Title: Process for the decomposition of titanium ore
IPC: C22B34/12
Filed: 1956-04-18
Abstract: Oxidic titanium ores, particularly ilmenite, are decomposed with sulphuric acid to form a titanyl sulphate solution by treating the ore at a temperature above 130 DEG  C. with a quantity of sulphuric acid of between 45 and 75 per cent strength in a quantity which contains the stoichiometric amount necessary together with an excess which is at least one and a half times the stoichiometric quantity. The reaction mass is cooled to separate the titanyl sulphate crystals and the surplus acid is re-cycled to the decomposition process with the addition of that amount of sulphuric acid which has been consumed.  The decomposition is preferably effected at 150 DEG  to 175 DEG  C. with an acid having a preferred concentration of 55 to 65 per cent.  The make-up sulphuric acid which is added to the circulating acid may be obtained by concentration of the dilute acid which may be formed by the hydrolysis of the titanium salt obtained. According to a typical example, a circulation acid of 60 per cent strength, pre-heated to 130 DEG  C., is mixed with ilmenite and concentrated sulphuric acid to provide the required excess.  The temperature rises to 165 DEG  C. and after reaction the acid crystal mixture is cooled to 60 DEG  C., and filtered.  The sulphate crystals are separated and washed with water, the washings being added to the preceding filtrate, which after concentration, is re-cycled to the process.  The filter cake is extracted with water during which the trivalent iron is reduced with scrap iron and liquor obtained is allowed to settle, filtered, evaporated and the ferrous sulphate crystallized and removed.  Titanium dioxide pigment is obtained in the usual manner.

Title: Making synthetic resins and varnishes therefrom
IPC: C08G8/28
Filed: 1940-07-30
Abstract: 544,916. Phenol aldehyde resinous condensation products. CHARLTON, W., HARRISON, J. B., WATERS, R. B., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 30, 1940, No. 12352. [Class 2 (iii)] Condensation products suitable for incorporation with drying oils to give air drying or stoving varnishes are obtained by heating methylol compounds as hereafter defined of p-aryl or p-alkyl substituted phenols or of #-#-di (4-hydroxy-3-methyl phenyl) propane with methallyl alcohol at 80-140‹C. in presence of an acidic catalyst until substantially no more water is eliminated and excess methallyl alcohol is distilled off. The viscous liquid resinous composition thus obtained may be used as such or further hardened by heating to 150-230‹C. until solid when cold. The methylol compounds comprise phenol di-alcohols or the phenolic methylol containing condensation products which are formed by heating these di-alcohols in the early stages of heat hardening them to resins, so that they split off water and a minor proportion of formaldehyde and yield fusible, soluble low molecular condensation products which still contain re-active metbylol groups ; there are specified-p-tertiary butyl phenol, p-tertiary amyl phenol, p-(α, x : γ, γ, tetra-methyl-n-butyl) phenol ; p-phenyl' phenol : #<SP>1</SP> : #-di-(4-hydroxy-3-methyl-phenyl) propane (di-o-cresylol propane). Catalysts comprise inorganic acids, p-toluene sulphonyl chloride, zinc chloride, aluminium chloride and may be removed prior to hardening by treating with acid binding re-agents, e.g. calcium carbonate. The re-action may be effected in presence of a solvent, e.g. benzene, toluene, or excess of the methallyl alcohol. In examples (1) p-tertiary butyl phenol di-alcohol is prepared by re-acting p-tertiary butyl phenol, formaldehyde, water and caustic soda at room temp. the temperature rising to 30‹C., a white solid separating after 20 hours ; concentrated hydrochloric acid is added the temperature being kept at 30‹C. whereupon a pale yellow oil separates. This product after purification is re-acted with methallyl alcohol and phosphoric acid under reflux for 15 hours. The re-action product is cooled, filtered and steam distilled and is then heated to 180‹C. in carbon dioxide for 2 hours, a resin of m.p. 91‹C. being obtained. Specifications 409,397 and 511,511 are referred to.

Title: Metal recovery process
IPC: C22B23/00
Filed: 1959-04-13
Abstract: In a process for treatment of a leach solution containing nickel, cobalt and zinc, in which the nickel is partially precipitated by treatment with a reducing gas under pressure, and %  the remainder of the nickel together with the zinc is then precipitated as complex ammonium sulphates which are recycled, the composition of the solution is adjusted prior to the initial nickel separation so that after that separation the mol ratio of zinc: nickel lies in the range 0.5 : 1 to 5:1.  Adjustment of the zinc content is effected by addition of zinc sulphate or by a controlled precipitation of zinc sulphide from the acidified solution.  The zinc nickel ammonium sulphate may be recycled to the zinc content adjustment stage, or may be added to the feed solution between that stage and the nickle precipitation stage, in which case a suitable allowance is made at the adjustment stage.

Title: Improvements in and relating to apparatus for measuring or indicating speeds and distances or revolutions run
IPC: G01P5/06
Filed: 1923-05-10
Abstract: 219,761. Brewerton, A. E. May 10, 1923. Differential speed indicators. - The member, the speed of which is to be measured, is arranged to control by means of an electric device an independently driven shaft so that it runs at the same speed as the member. The electric device operates the variable speed gearing by which the independent shaft is driven from a constant speed motor, and the position of the gearing indicates the speed of the first member. The Figure shows the application to a ship's log in which an impeller 1 drives a shaft 4 causes a follower magnet 8 within the watertight casing to rotate at the same speed. On the magnet is arranged an arm 9 adapted to contact with contacts 22 or 23 on the intermediate shaft 21a. This shaft is driven by a friction disc 19 on a constant speed shaft 18, a friction roller 20 rotating on a nut 35 on a shaft 33, and a friction disc 21. The roller 20 is moved axially automatically in order to keep the speeds of the shafts 4, 21<a> equal. The automatic gear comprises a shaft 28 which is driven from the shaft 18 bv a belt 29, and which is fitted with friction discs 30, 31. One or other of these discs may contact with a friction disc 32 on the shaft 33 according to the axial position of the shaft 28. The shaft may be moved axially in one direction or the other by electromagnets 24, 25 and cooperating armatures 26, 27. The electromagnets are in circuit with a battery 10 and the contacts 22, 23 as shown. In operation, if the arm 9 catches up with the contact 22 owing to a difference in speed, the magnet 25 will be energized and the shaft 28 will be moved to bring the discs 30, 32 into engagement and so rotate the shaft 33. The roller 20 is thus moved to change the gear ratio and restore equality of speed in the members 21a, 8. The reverse action occurs if the contact 23 catches up with the arm 9. The axial position of the friction wheel 20 along the shaft 33 is an indication of the speed of the impeller 1. A step-by-step transmitter 34 on the shaft is connected by step-by-step motors to repeat instruments upon which an indication of the speed is given. To register revolutions run or distance travelled, a contact 36 on the disc 21 is adapted to engage a contact 37 once every revolution to energize electrically-operated counters in the repeat instruments. The method of driving the part 8 from the shaft 4 may be modified. The speed of the motor 11 driving the shaft 18 is kept constant by an adjustable governorcontrolled friction brake 14. A clockwork motor may be used. The Provisional Specification describes an arrangement whereby a step-by-step transmitter actuated by the chaser svstem causes an electric motor to run synchronously with the impeller, the brushes of the transmitter being connected to the speed indicating instruments.
