Abstract: 1416884 Multi-diaphragm pumps C HUGHES 8 May 1973 [17 May 1972] 23088/72 Heading F1A An hydraulic pump comprises a casing 2 divided into a number of chambers 12, 14, 16, 18, 20 arranged in series between an inlet 12a and outlet 20a, successive chambers in the series being separated by respective flexible diaphragms 4, 6, 8, 10 such that successive diaphragms are displaced in opposition to each other. Diaphragms 4, 8 are fixed to a shaft 58 and diaphragms 6,10 to a sleeve member 64, the shaft 58 and member 64 being relatively slidable. Crank arms 46, 48 connect the shaft 58 and sleeve member 64 respectively to eccentrics 42, 44 on an input shaft 36, eccentrics 42, 44 being 180 degrees out of phase. Sleeves 28 extend between the diaphragms and have annular end portions sealingly engaged therewith by clamping collars 68, 70. These collars are fixed to a respective one of the shaft 58 and sleeve member 64, the collars for clamping diaphragm 6 being rigidly attached to sleeve 64 via rods 66 passing slidably through diaphragm 8 and bolts 72. Starting from the position shown where diaphragms 4, 8 are in their uppermost position and diaphragms 6, 10 in their lowermost position, it will be seen that continued rotation of input shaft 36 causes diaphragms 4, 6 to move away from each other to expand chamber 14, such suction lilting diaphragm 4 from its outer peripheral seat to permit liquid to enter via inlet 12a and chamber 12. Subsequent compression of chamber 14 pushes liquid into the next, expanding, chamber 16 and in this way liquid is transferred through the chambers towards the outlet. On an upward movement of diaphragm 10 fluid is pushed out of chamber 20 through outlet 20a, and on downward movement of diaphragm 10 fluid is still ejected from outlet 20a since the chamber 18, bounded by two diaphragms 8, 10, is compressed at twice the rate that chamber 20, bounded by only one diaphragm 10, expands.

Abstract: 583,831. Electrolytic recovery of aluminium; fused electrolyte apparatus. AERLEC (ALUMINIUM), Ltd., and PARRY, E. A. Nov. 25, 1944, No. 23526. [Class 41] A cell for the recovery of pure aluminium from alloy scrap containing, for example, not less than 80 per cent. of aluminium with relatively small amounts of copper or other metals by the three layer process comprises an electrolysing chamber 10 communicating by a submerged passage 13 with a reservoir chamber 11 for molten crude metal which may be fed from a pouring trough 29. Electric heating elements 14, 15 are arranged in vertically spaced zones round both chambers ; these may be tungsten steel wires enclosed in hard glass or silica tubes' and embedded in the walls. Surrounding both chambers and the heaters is a jacket 17 consisting of a double-walled shell of steel plate the interior of which is connected to a vacuum pump or is alternatively exhausted initially and sealed. The shell is set in a housing of insulating brickwork enclosed in an outer steel casing 19. The bottom of both chambers consists of a graphite plate 22 cemented by creosote pitch .and coke dust to a carbon block 23 to which the anode connection is made by a copper bus-bar 24 having lateral extensions. Connection to the cathode layer is made by a vertically movable graphite plate 26 of the same length as the electrolyzing chamber and one-eighth its width. Pure aluminium is removed from the cathode layer by ladling or by syphoning through silica tubing. The several zones of the heating elements are controlled by independent switches so that one or more may be connected selectively and successively to induce connection currents. The sides of the electrolyzing chamber are concave as shown, to promote movement of the electrolyte and prevent formation of a crust. The walls of the chambers may be of magnesia tiles or magnesia cement plaster. An adjustable auxiliary cathode 27 may be provided in the reservoir chamber to assist in melting the electrolyte when starting up. The cell is separated from its base 20 by a layer 21 of asbestos. To form the cathode layer a high purity aluminium tray with long handles at each end is lowered on to the surface of the molten electrolyte and pure molten aluminium poured into it whereupon the tray melts. The scrap metal to be fed to the. reservoir 11 may be melted in a tiltable crucible housed in the heat-insulating brickwork of the cell; alternatively, in a plant comprising a number of cells, the scrap metal may be fed to them by an overhead conveyer system. The cells may be connected in series. The anode layer should contain not less than 30 per cent., preferably 33 per cent., of copper at starting ; when the aluminium content of the layer is reduced to about 11 per cent., the alloy is run off by a tap not shown or is removed by ladling and renewed. A cover, not shown, is provided which may consist of a hollow steel member packed with indurated asbestos fibre.
