Title: Method for production of metallic cobalt from the nickel solvent extraction raffinate
Inventor: TORRES VANESSA DE MACEDO
IPC: C22B3/00
Filed: 2007-10-19
Abstract: "Method for production of metallic cobalt from the raffinate from solvent extraction of nickel". Said method comprises the following stages: (A) obtaining the raffinate from solvent extraction of nickel, for production of cobalt; (B) adding a sulfide precipitation agent to said raffinate, for cobalt sulfide and zinc sulfide precipitation; (C) removing all ammonia from the sulfidized pulp (solids and liquid); (D) subjecting the filtered solid - cobalt sulfide (and impurities) - to atmospHeric leaching; (E) reducing to a minimum the zinc concentration in the cobalt round, by means of solvent extraction with D2EPHA extractant diluted in Escaid 110 solvent or equivalent solvent, in any solvent extraction system comprising the required number of extraction, scrubbing, and stripping stages, with resident time of not less than 1 minute at each of the stages used; (F) performing nickel removal by ion exchange, for nickel purification; (G) adding sodium carbonate to the solution, for cobalt carbonate precipitation; (H) leaching the produced cobalt carbonate in a system that utilizes an acid, preferably sulfuric acid, and more preferably, the anolyte from cobalt electrolysis; (I) performing cobalt electrowinning so as to recover the cobalt from the solution in its metallic form; and (J) allowing the metallic cobalt to settle on insoluble stainless steel plates during the time required for production of the cobalt cathodes.

Title: Fuel Injector for a Gas Turbine Engine
Inventor: TOON IAN JAMES
IPC: F23D14/76
Filed: 2009-06-03
Abstract: A fuel injector nozzle 36 has a heat shield provided around a fuel discharge orifice 42. The heat shield has a sliding expansion joint 49, and a drip guard 56 arranged to cover the expansion joint and protect the joint from being wetted by falling fuel ejected through the fuel discharge orifice. The heat shield may include a first heat shield member 47 and a second heat shield member 48 which slide against one another and together form the expansion joint. The second heat shield member may be frusto-conical or cylindrical in form, and the drip guard may be concentrically arranged around a region of the second heat shield member. The fuel nozzle addresses problems associated with the nozzle being wetted with fuel purged from fuel lines upon engine shutdown, and is particularly suited to marine or industrial gas turbine engines having a plurality of radially oriented combustion chambers with respective fuel spray nozzles.

IPC: C10J3/00
Filed: 1928-04-04
Abstract: 314,601. Tully, Sons & Co., Ltd., and Tully, A. V. April 4, 1928. Water-gas plant. - A cyclone dust extractor adapted to recover sensible heat is provided between a water gas generator and the stack valve and has a steam inlet to enable steam to be passed through it to the generator. During the blow, air admitted through a valve 5 beneath the generator grate 6 passes through the fuel into a further combustion chamber 8 with checker work 4 which receives air through a valve 9. Combustion products pass off. through a conduit 10 which enters tangentially a dust collector 11 acting as a cyclone extractor. Solid particles which are flung outwardly finally collect in a pipe 12 for periodical discharge through a valve 25 and the waste gases pass through openings 13 in a central flue 14 leading to the stack pipe 15. Sensible heat is given up to the brickwork forming the lining 17 and central flue. Steam is admitted through a pipe 18 for the up run, gas passing through the fuel in the retort to an outlet 20. For the down run steam enters the vessel 11 through a pipe 19 and is superheated before passing downwardly through the generator to an outlet 21. Oil may be admitted through an inlet 22 to the checker work 4 in which case part of the water gas produced during the up run is caused to pass up the cheokerwork and carry off oil vapours which are fixed in the dust extracting vessel, the enriched gas passing off through an outlet 23.

An electrical switching system comprises means for forming a visual display of information pertinent to at least one of a number of possible switching operations superimposed upon a multiplicity of electrical switches at least some of said switches being in register with selected parts of said display and representing a choice of switching operation relating to said selected parts. A cathode ray tube is controlled by a computer to produce a display superimposed upon a matrix of row and column wires, mutually insulated at the cross-points. By placing his finger on a cross-point, an operator alters the capacitance between the two wires thereat. The rows and columns are scanned in turn, e.g. by reed relays controlled by electronic logic, to detect the change in capacitance, the changed location being identified to the computer which alters the display and/or controls a system in response. The controlled system may be an electricity supply network, route indicator, teaching machine, retail shop, manufacturing plant, or air booking system. Measurements in the controlled system and the results of calculations may also be displayed.

Patent GB-596369-A (GB)
Title: Improvement in art of cleaning fabrics and like articles, and mechanism therefor
IPC: D06F33/36
Filed: 1944-05-30
Abstract: 596,369. Washing-machines. AMERICAN MACHINE & METALS, Inc. May 30. 1944, No. 10377. Convention date, May 22, 1943. [Class 138 (ii)] Detergent is supplied to the container of a clothes washing-machine until a suds blanket of predetermined height is produced, and the contents of the container are then agitated until there is a predetermined rise in the suds level which operates means for automatically signalling the attainment of this condition and/or for automatically discontinuing the agitation. Preferably, the amount of detergent added is insufficient, to produce the predetermined rise in suds level with a single treatment so that a succession of treatments are required before the aforesaid means are operated to indicate that the clothes are clean and/or to switch the machine to the next stage of the washing process. Decreasing quantities of detergent are added at successive treatments since less is required to produce the initial suds blanket as the clothes become progressively cleaner. In the machine shown, a rotary washing drum 10 driven by a motor 23 is mounted in an outer container 4 to which hot and cold water are supplied from mains 30 and 40 by opening valves 31 and 41. The valves are held open by detents 33 and 43 until tripped by a rod 52 attached to a float in a well 50 connected to the container 4, which occurs when the container has been filled to the correct level. Detergents are supplied to the container from tanks 60, 61 and 62 by manipulating valves 63, 64 and 65. There are two suds level responsive devices, an upper one, 85, which determines the predetermined rise in suds level, and a lower one, 84, which determines the height of the initial suds blanket. Each comprises an electrode projecting into the casing and adapted, when contacted by the suds, to energize a relay 82 or 83 controlling a device 74 or 75, which may be an indicator lamp and/or an appropriate control device for the machine. Diaphragm devices may be used as an alternative to the electrodes. In operation, the drum is set rotating and the valves 31, 41 opened to fill the container to a predetermined level. Detergents are then admitted by opening the valves 63-65 until an initial suds blanket reaches the lower electrode 84 when the device 74 responds. The detergent supply is then cut-off, which may be done automatically by the device 74, and' agitation continued for a fixed period, after which a dump valve 90 is opened to empty the container. This procedure is repeated, a higher suds level being attained on each occasion, until the electrode 85 is reached and the device 75 responds. Rinsing is then carried out, and this may be initiated automatically by the device 75. To clear the electrodes of scum, hot water or steam is directed over them by nozzles 107, 108 each time the dump valve 90 is opened, a valve 105 in the supply pipe to the nozzles being connected to the dump valve for operation therewith.
