Patent GB-678621-A (GB)
Title: An improved method of and means for thickening and/or washing mixtures of solids and liquids
IPC: B01D21/00
Filed: 1950-01-18
Abstract: 678,621. Gravity-separation apparatus. SWINDIN, N. April 18, 1951 [Jan. 18, 1950], No. 1340/50. Class 46 A method of thickening a mixture of solids and liquid consists in continuously delivering the admixed solids and liquid into a vessel having a base of restricted dimensions into which the solids will settle under gravity, introducing into the vessel at or near its restricted base a quantity of liquid sufficient to fluidify the settled solids and raising and removing the solids from the vessel by the operation therein of an air-lift the lower end of which is located near the base of the vessel. By using a wash liquor (e.g. water) as the fluidifying medium the solids can be washed at the same time as they are thickened. Further washing can be achieved by discharging the thickened solids from the air-lift in the thickener into a washing vessel constructed in the same way as the thickener. The mixture of solids and liquid enters a vessel 2, Fig. 1, by pipes 1 and 13, the solids settling into a hollow leg 3 and the liquid overflowin into a launder 6 whence it may run to waste at 7. Some of the liquid may however pass from the launder 6 into a pipe 8 and thence by an air lift 9 up a pipe 10 to a tank 11. The tank 11 is situated at a height such that liquid passing from it down a pipe 12 will have sufficient head to overcome the resistance of the column of solids in the leg 3 and fluidify the column. The fluidized solids may then be discharged from the down-turned upper end of a lift-pipe 4 by the operation of an air-lift 5. In Fig. 2 (not shown), the fluidifying is performed not by liquid flowing from the top of the vessel 2 but by an independent supply of water or other washing liquid from a tank 11 (as in the apparatus on the left of Fig. 4). In the fluidifying action the washing liquid additionally displaces most of that small amount of the original liquid which occupies the interstices of the solids so that the air lift 4, 5 delivers a thick slurry of solids in the washing liquid. In a modification of Fig. 2 (not shown), the discharge from the pipe 4 may be passed to the pipes 1. 13 of an exactly similar apparatus. In Fig. 4 the overflow liquid from the second washer (that on the left) instead of passing to waste is used as the fluidifying and washing liquid in the first washer. The washing in this case is not so thorough as in that of the modification not shown but wastage of liquid is avoided. Variation of head of the fluidifying liquid may control through an electrical or mechanical relay the operation of the air-lift. The process may be used for washing ferrous sulphate, precipitated during concentration of sulphuric acid, by means of the original weak acid solution. The gangue from lead ores leached with hot acid brine is fluidified by brine rather than water since the latter would precipitate lead chloride which would remain in the gangue and be wasted.

Title: Aluminothermic or like exothermic process for making non-ferruginous alloys
IPC: C22C1/02
Filed: 1945-01-22
Abstract: An aluminothermic or like exothermic process for making non - ferrous metal alloys, in which one or more of such metals are molten in a crucible heated from the outside, whilst on top of this molten metal or metals, in the same crucible, an aluminothermic or like exothermic reaction is started in an exothermic mixture added directly to the melt and capable of liberating another non-ferrous metal with which the first mentioned molten metal or metals is or are alloyed.  By the invention a metal of higher melting point, e.g. chromium manganese, titanium, vanadium, molybdenum, tungsten, nickel, cobalt, niobium, zirconium or beryllium, may be added to and alloyed with a metal of lower melting point e.g. aluminium, magnesium, copper, lead, tin or zinc.  The correct pouring temperature of the alloy may be achieved by the heat of the reaction together with that added by heating the crucible from the outside, or this temperature may be increased by the addition of barium peroxide.  The slag, which may be kept liquid by fluxes, may be used as a protective layer during the latter part of the process.

Patent GB-174370-A (GB)
Title: Improved process for rendering soluble crude phosphate
IPC: C05B11/14
Filed: 1922-01-23
Abstract: Soluble phosphates are obtained by acting on a mixture of crude phosphate and alkali sulphate with hydrochloric acid gas in presence of water.  The addition of water may be effected by incorporating with the mixture loosening-substances such as infusorial earth which can absorb moisture and still remain powdery.  The required moisture may be added either before or after admixture with the crude phosphate and alkali sulphate. Alternatively, powdery substances naturally containing large quantities of water, such as crude brown coal, may be added. Finally, the required moisture may be added in small successive portions without the use of a "loosening substance." The reaction is preferably carried out in stationary cylinders having stirring-shafts, the mixture advancing slowly in the cylinder against a current of hydrochloric acid gas.

Title: Improvements in or relating to thermostatically controlled valves for gas cooker ovens
IPC: G05D23/02
Filed: 1944-02-03
Abstract: 577,996. Gas cookers. PARKINSON STOVE CO., Ltd., LUSK, A., and TAYLOR, H. G. Feb. 3, 1944, No. 2025. [Class 126] [Also in Group XXIX] In a thermostatically operated valve for gas cookers in which the valve casing is mounted at the back of the oven and the usual thermostat rod and tube extend through the oven space to a rotatable setting head mounted at the front of the oven, the setting head is either mounted independently of the thermostat and connected thereto by a part slidably keyed to a screwthreaded member which engages the thermostat rod and screws into the thermostat tube or a part secured thereto, or the setting head is mounted on a stem carried by the thermostat tube which can be adjusted by screwing its rear end in or out of the valve casing. As shown in Fig. 1, the valve casing 10 is in one piece and is mounted outside a casting 11 at the back of the cooker so as to permit limited universal adjustment by part spherical surfaces 12, 13. The thermostat tube 20 is screwed into the inner end of the valve casing and the rod 21 abuts a disc 22 which carries a sealing bellows 23. The other end of the rod 21 abuts an adjusting screw 31 in a sleeve 32 fixed to the front end of the thermostat tube 20. The setting head comprises (1) an indicating dial 25 visible through an aperture 28 in a visor 24 pressed out in the front of the cooker frame, (2) a spindle 29 to which the dial is secured by a sleeve 26 and a set screw 34, and (3) and adjusting knob 27. The spindle 29 has a tongue 30 projecting into a slot in the screw 31. Resilient washers are arranged on either side of the visor 24 between the dial 25 and a collar through which the set screw 34 can pass at any of a number of holes. The adjustment can be preserved after calibration and before mounting in the oven by a set screw 33 which is subsequently removed. Fig. 2 shows a modification in which the visor 54 is a separate plastic moulding removable as a unit with the indicating dial 55, the knob 58 and the setting spindle 52 and secured to the front of the cooker by wing bolts 56. The tongue 51 on the setting spindle is wedge-shaped and the adjustment between the screw 50 and the thermostat tube 49 is locked temporarily after calibration by a screwed bush 53 and a lock nut 53a the bush being subsequently backed away from the enlarged head of the screw 50 to the position shown. In a further modification, the setting spindle adjusts the position of the thermostat tube relative to the inner end of the valve casing and means are provided for locking this adjustment temporarily after calibration. To ensure alignment between the valve and the_ setting head, the setting spindle and the inner end of the valve casing are mounted in aligned holes in spaced depending lugs integral or rigid with the crown of the oven. In a further form, alignment is secured by mounting the valve casing in an aperture in the cooker frame giving appreciable radial clearance.
