Title: Purification of mercury
IPC: C22B43/00
Filed: 1974-01-25
Abstract: 1425670 Purifying mercury BAYER AG 25 Jan 1974 [27 Jan 1973] 03486/74 Headings C7B and C7D The purification of mercury contaminated with iron, chromium, vanadium or other metallic impurities less noble than mercury from the electrolysis of alkali metal chlorides is carried out by treating the impure metal with an aqueous solution of sulphuric acid containing mercury(I) sulphate in solution or suspension, separating the purified mercury from the contaminated solution, washing it and recycling back to the electrolysis cell. Aqueous sulphuric acid and mercury (I) sulphate, from an electrolytic cell 4 (the cementing solution) is passed into a cup 3 and comes into contact with contaminated mercury from the horizontal amalgam decomposer 2 of an alkali metal chloride electrolysis cell 1. The liquids are turbulently mixed by a rotor 5 and the purified mercury passes into a chamber 7 where it is washed with dilute sulphuric acid prior to returning to the cell 1. The spent cementing solution 9 together with the spent anolyte solution 11 are further treated to remove salts by precipitation prior to recycling. Where a vertical amalgam decomposer 14 is used, the contaminated mercury is pumped 15 back to the cell via a mixing zone 16 into which the cementing solution is introduced. The cementing process is preferably carried out at 20-100‹C with 0.1 to 1 molar sulphuric acid, and all the containers should be resistant to the cementing solution.

Abstract: 568,255. Cutting-machines for paper &c. TRIGGS, W. W. (Cameron Machine Co.). March 1, 1944, No. 3861. [Class 31 (i)] In a slitting-machine for webs of paper &c. 13, in which circular shearing discs 12 engage discs 11 under spring pressure, improved means are provided for giving the discs a double adjustment by moving the discs 12 into and out of sidewise engagement and into and out of overlapping arrangement, the latter adjustment always taking place when the discs are out of sidewise engagement. The discs 12 are adjustably secured in a carrier 17 mounted on a block 18 provided with journals 26, the axis of which is parallel to the fixed axis 16 of the discs 11. To the block 18, Fig. 7, is secured a Geneva wheel 35 adapted to be rotated to bring the discs 12 into and out of overlapping arrangement, and a Geneva wheel 37 is adapted to rotate a screw-threaded member 27 connected to the journal 26 which engages a fixed internally-threaded bushing 33, so that rotation of the screw 27 causes axial movemsot of the journal and the block 18. The Geneva wheels 35, 37 are operated by rollers 45, 46 on arms 43, 44 carried by a shaft 19 which is operated by an arm 20, Fig. 1, movable by hand into positions controlled by fixed stops 22, 23. To displace the discs from cutting position shown in Fig. 1, the arm 20 is moved clockwise and roller 46 operates wheel 37 to cause rotation of the screw 27 with axial movement of the discs 12, and this is followed after a short interval by the action of roller 45 on the wheel 35 to cause rotation of the journal 26 and movement of the block 18 and discs 12 away from the disc 11. On reversal of the arm 20, the discs 12 are moved towards the disc 11 prior to the sidewise movement of the discs into cutting relation. The arms 43, 44 are integral with locking members which prevent rotation of the Geneva wheels except when the rollers 45, 46 are in action. The shaft 19 is fitted with a ratchet 25 which can be engaged by a pawl 24 when it is desired to prevent backward motion of the shaft 19.
