Abstract: 872,698. Welding by pressure. TRIANGLE PRODUCTS Ltd. Sept. 7,1959 [Sept. 13, 1958], No. 29382/58. Class 83 (4). A spot-welding machine comprises a compressible member to propel cooling fluid through conduits in the electrodes and/or their holders when the electrodes are brought together to compress the member, re-separation of the electrodes allowing the member to expand and draw in further fluid. A welder 2 mounted on a bench top 1 has electrode arms 3, 4 with electrode tips 3a, 4a which are brought together by depressing a treadle 5 secured to a block 7 pivoted in a bracket 6. The block has an extension 7a for the swivel connection 8 of a link 9 connected to the movable arm 3 and the block supports a member 10 carrying a padded plate 11. Secured to the underside of the bench is a carrier 13 supporting a compressible rubber bulb 14 in a flexible tube 15 in which are arranged two non-return valves 16, 17, the valve 16 allowing water flow into the bulb from supply pipe 18 and valve 17 allowing expulsion of water to the feed-pipe 19. The latter pipe is connected to conduits in the electrodes; the return water therefrom passing into a tank from which the pipe 18 receives its supply. The return pipe from the electrodes may discharge its water as a spray or over heat-exchange deflectors for cooling. When the treadle is depressed to bring the electrodes together the member 11 deforms the bulb to force water along the pipe 19 and through the electrodes and when the treadle returns the bulb takes up its normal shape and is refilled with water. In a modification the bulb is held between two plates, spring-pressed apart, one fixed to the treadle and the other receiving the foot pressure. The conduits to the upper and lower electrode tips may be in series or parallel. Specification 792,766 is referred to.

Title: Process for decomposing minerals
IPC: C22B1/08
Filed: 1962-08-03
Abstract: Minerals containing titanium (e.g. ilmenite) are treated at 55-65 DEG C. with concentrated hydrochloric acid such that 2-5 mols. of hydrogen chloride per mol. of dissolved titanium are obtained in the extract solution which is then worked up to recover titanium values. The process may be continuous and preferably counter-current.  The titanium containing ore is dissolved in acid as above, the ferric iron reduced to ferrous iron, the solution saturated with hydrogen chloride to precipitate chlorides which are filtered off, hydrogen chloride removed, advantageously in vacuo, the filtrate diluted and heated after which titanium dioxide dihydrate is precipitated and separated, followed by heating to dehydrate yielding titanium dioxide.  The filtrates may be concentrated by introduction of hydrogen chloride and then recycled to the ore decomposition. Reduction of trivalent iron may be effected by iron, aluminium, zinc, hydrogen, hydroxylamine, sulphur dioxide or formaldehyde or by electrolysis. Titanium tetrachloride may be obtained by adding potassium chloride to the filtrate after separation of the chlorides as above, thus yielding potassium hexachlorotitanate which is filtered off and heated to above 400 DEG  C. giving titanium tetrachloride.  The potassium hexa-chlorotitanate may also be hydrolysed to titanium dioxide.  Solutions containing titanium tetrachloride may also be returned to the ore decomposition process.
