Title: Improvements in or relating to electrical timing devices
IPC: G04F3/06
Filed: 1944-09-14
Abstract: 585,373. Control systems for consumption apparatus. LINDARS, H., and SMITH, C. H. Sept. 14, 1944, No. 17619. [Class 38 (iv)] A timing device which causes a secondary current to flow for a period which is a definite fraction of the time for which current flows in a primary circuit during single or successive intervals, comprises an eddy current motor having a disc 2, Fig. 1, geared to a disc 7 and actuated by voltage and current coils 3 and 4 and 5 respectively, the current coils acting in opposition. Disc 7 carries an armature 11 co-operating with coils 12 and 13 and a pin 8 which is effective to close contacts 9 or 10 respectively. When a primary current flows in the circuit of electromagnet 1a, controlling contacts 1, relay 14 operates to energize coil 4 from source 16 through variable resistance 17 and contacts 15. Pin 8 moves towards contacts 10, which eventually close to energize relay 19, contacts of which operate as follows : contact 20 closes to effect a hold-on circuit for the relay ; contact 22 connects coil 5 to source 16 through variable resistance 29 ; contact 23 disconnects coil 13 and connects coil 12 to source 16 ; contact 24 closes an indicating circuit OG ; contact 25 closes the secondary circuit 26 to be controlled ; contact 27 prepares a circuit for relay 28 which becomes energized and opens its contacts 21 to de-energize relay 19 when pin 8 closes contacts 9 due to the combined action of coils 4 and 5. A continuously running timing mechanism, such as a synchronous motor-driven switch 18, is provided to ensure alternatively energization of relay 19 and therefore the secondary circuit 26 at regular intervals, without the delay attendant on closing of contacts 10 by the pin 8. Should the switch close before, a primary current operates relay 14 to energize coil 4 to drive the disc 2 forward, relay 19 will only be energized momentarily, when the pin 8 will close contacts 9 to open the circuit of relay 28 at contact 21. If desired, the speed of switch 18 may be made variable. Coils 4 and 5 may comprise a single centre tapped coil and the disc 7 may be replaced by an arm. Specifications 566,911 and 582,094, [Group XXXVIII], are referred to.

Title: Improvements in or relating to precipitate flotation processes
IPC: B03D1/001
Filed: 1963-05-03
Abstract: Metal ions are recovered or removed from solution, e.g. from leach liquors, mine waters or industrial effluents by adding hydroxyl ions to precipitate metal hydroxides, adding an organic cationic or anionic "collector reagent," and buoying the precipitate to the surface with a flow of gas, preferably air. Metals which may be recovered include Al, Be, Mg, Zn, Cd, Hg, Sb, Pb, Fe, Mn, Cr, Co, Ni, Cu, Ag, In, Ti, Mo, V, Lu, Ce, Pr, Nd, U and Th.  Hydroxyl ions are supplied as calcium or sodium hydroxide (preferred) or the hydroxides of ammonium, potassium, lithium, rubidium or caesium, to give a solution pH sufficient for optimum precipitation of any desired metal, e.g. pH 6-9 for Cu, 4.5-6.0 for Fe.  The "collector reagents," which must have hydrophilic and aerophilic centres of activity, are preferably derived from plant and animal triglycerides and may be amines or quaternary ammonium derivatives (cationic) or oxhydryl or sulph-hydryl compounds (anionic), where metal or hydrogen is connected to the hydrocarbon residue via oxygen or sulphur; less than one mole collector per mole metal to be recovered is used.  The collector may be added in water or an alcohol and, if desired, in the vapour phase.  Selective recovery, e.g. of copper and iron in concentrations less than 1 gm./litre is effected by adding hydroxyl ions up to the pH of optimum precipitation of the first metal, adding the collector, buoying the precipitate to the surface, removing it, adding further hydroxyl and repeating the process for each metal. Examples describe the recovery of iron, copper, chromium and magnesium and the selective recovery of iron and copper, and iron, copper and zinc.  Example X relates to the removal of an anionic blue dye from water by adsorption on aluminium hydroxide and flotation of the latter.ALSO:Metal ions are recovered or removed from solution by a flotation process in which hydroxyl ions are first added to precipitate metal hydroxides, an organic anionic or cationic collector reagent is then added, and the precipitate is buoyed to the surface by a flow of gas, preferably air, bubbles.  The collector reagent may be added in water or an alcohol and, if desired in the vapour phase and it must contain hydrophilic and aerophilic centres of activity.  Preferred collectors are cationic and anionic derivatives of plant and animal triglycerides e.g. amines or quarternary ammonium salts (cationic) or oxydryl or sulphhydryl compounds (anionic), specific substances preferred being petroleum sulphonates, primary amines from soya fatty acids, di-amines from coconut fatty acids, quaternary ammonium chlorides from lauryl amines, a -sulpho lauric acid, and sodium or potassium coconut or caprylic acid soaps such as Neo Fat 265 or Neo Fat 10.

Title: Improvements in a method of recovering uranium from ores containing it
Inventor: BRIS JEAN LE
IPC: C01G43/025
Filed: 1956-06-12
Abstract: Hydrated uranium dioxide is recovered by precipitation with nascent hydrogen from a solution of a hexavalent uranyl-alkali metal or -ammonium carbonate solution obtained from a uranium ore. The solution may be obtained, e.g. by directly leaching the ore with sodium carbonate or bicarbonate (with an oxidizing agent if necessary) or by treating with an excess of sodium carbonate the product of acid leaching (with an oxidizing agent if necessary). In examples, the former method is used, the leaching being performed at 70 DEG  or 80 DEG  C.  The nascent hydrogen is preferably generated by electrolysis of the solution (see Group XXXVI) in the presence of a hydrogenation catalyst such as nickel, platinum, palladium, iron or mercury or alloys thereof such as an aluminium/nickel alloy.  The catalyst may be finely divided and used as a suspension or may be in the form of a fine grid, preferably located close to the cathode. After removal of the hydrated uranium oxide, the solution can be reused to attack further quantities of the ore.  A nickel catalyst, if used, may be separated from the precipitate magnetically.

Abstract: 721,016. Refrigerators. GENERAL MOTORS CORPORATION. July 2, 1953 [July 8, 1952], No. 18312/53. Class 29. In a refrigerator 10 having freezer and storage compartments 12, 11 cooled by seriesconnected evaporators 28, 29, the storage compartments having an electric heater 39, the compressor unit 25 and heater 39 are energized by a thermostat 43 controlled by a thermal bulb 62 responsive to the freezer compartment temperature when that temperature exceeds a predetermined maximum. The temperature of the storage compartment is detected by the bulb 69 of a second thermostat 49 actuating two switches 47, 54 in such a way that, when the storage compartment temperature exceeds a predetermined maximum, the switch 47 energizes the compressor unit and the switch 54 de-energizes the heater 39 irrespective of the condition of the thermostat 43. The heater may be a lighting bulb which is switched on by a door-actuated switch 46 whenever the door is opened. The pipe 33 connecting the evaporators 28. 29 acts as a restrictor to ensure differential operating temperatures. The heating of the storage compartment prevents too low a temperature therein at low ambient temperatures.
