Title: Recovery of nickel
IPC: C22B23/06
Filed: 1970-03-09
Abstract: 1300445 Extraction of nickel ETHYL CORP 9 March 1970 [17 March 1969] 11119/70 Heading C1D [Also in Division C1] A process for the recovery of nickel from mixtures, particularly nickel ores, which contain cobalt and/or copper includes the steps of forming an ammoniacal solution of a nickel salt from the mixture and treating this with carbon monoxide, e.g. synthesis gas, in the presence of cyanide ion to form Ni(CO) 4 . The carbonyl may then be decomposed to nickel metal or converted to halides or organic compounds of nickel. The preferred source of nickel is a sulphide ore concentrate; this is suspended in aqueous ammonia and aerated to give the nickel solution, also containing any Co or Cu which may be present, and to precipitate any iron as ferric oxide hydrate. During the carbonylation, which is preferably carried out at 200 to 2500 psig and 100-200‹ C, Cu is reduced to the metal and Co to [Co(CO) 4 ], which may be recovered separately. The carbonylation is preferably carried out in the presence of a water-immiscible solvent to extract the Ni(CO) 4 .

Title: Improvements in and relating to gauging apparatus
IPC: G01B13/06
Filed: 1948-04-28
Abstract: 654,592. Linear-dimension gauges. SAND-VIKENS JERNWERKS AKTIEBOLAG. April 28, 1948, No. 11627. Convention date, April 30, 1947. [Class 106 (ii)] [Also in Group XXIX]  A controlling or indicating device is operated in accordance with the dimension gauged by the action of differential pressures set up in two chambers 3, 4 in the cylindrical body 1 of the apparatus. Compressed air is supplied to both chambers via a pressure regulator 10 and central chamber 8 communicating with chambers 3, 4 by means of passages 12; 13, surrounding a control-rod 11. Air escapes from the chamber 3 by means of an orifice 14 partially closed by a valve 17 and thence through a perforated diaphragm 15 and passage 16, and from chamber 4 via a passage 19 and gauging orifice 20. Air is also supplied to the inner chamber of a bellows 7 situated in the chamber 4 by way of a passage 25 having a valve-controlled outlet 23. Articles to be gauged, for example steel strip, are placed near the gauging orifice 20 so as to impede the escape of air therefrom, the consequent increase in pressure in chamber 4 causes the bellows 7 to compress, moving the control-rod 11 to the right. The resultant movement of the valve 17 to the right opens further the passage 14 and lowers the pressure in chamber 3. The increased pressure in chamber 4 and the decreased pressure in chamber 3 are communicated to a control or indicating device by means of conduits 27 and 26 respectively. Specification 596,641 is referred to. The Specification as open to inspection under Sect. 91 comprises also as shown in Fig. 2 (Cancelled) the valve member 53 corresponding to 17 in Fig. 1 actuating a slotted member 69 in which is located a pin 71 arranged to operate a toothed quadrant 73 and a pointer 74 to give a direct reading of the gauge measurement. A further modification also shown in Fig. 2 comprises the use of a feeler pin 68 connected to a rod 57 which, when the feeler pin 68 is pressed towards the body 66 by the article being gauged moves the nut 56 away from the face 55, permitting air to escape from the interior of the bellows 51. The lower pressure inside the bellows in chamber 49 causes the bellows to compress moving the conical valve 53 towards its closed position to restrict the escape of air from chamber 48, the pressure in which is thereby increased as the pressure in chamber 49 is decreased. This subject-matter does not appear in the Specification as accepted.

Abstract: 751,047. Electroluminescence. GENERAL ELECTRIC CO. April 27, 1954 [April 28, 1953], No. 12168/54. Class 39 (1). An electroluminescent screen comprises two grids of spaced parallel conductors at right angles, with a phosphor disposed between the grids which emits light in phase with the applied voltage. The terminal ends 16, 19 of the grid elements 11, 15 are connected to wiper contacts 21, 22 driven by electric motors 25 and operate to give scanning in a T.V. or oscilloscope display. The phosphor may be zinc sulphide, zinc oxide, zinc selenide, cadmium sulphide or cadmium selenide or mixtures thereof activated by one or more of copper manganese aluminium and silver (0.01-0.90 per cent). Fused zinc fluoride activated by manganese (1-6 per cent), thallium, cerium or lead is also satisfactory. Single crystals may be placed at the intersection points of the grids, but the phosphors are preferably applied by settling. The conductors 11 are of aluminium, silver, gold, nickel, applied to a support plate of glass or insulator-coated metal by vacuum deposition and cut by machine to remove a portion of the deposited metal and leave a pattern of parallel conductors. Silver paste may alternatively be applied as a coating and cut or applied as a series of parallel lines. The conductors 15 which overlie the phosphor layer are preferably transparent and are prepared as for the conductors 11 or by exposure of a plate to the vapours of silicon, tin or titanium chlorides and to a slightly reducing atmosphere. The preparation of single phosphor crystals by slow growth under reversible conditions is described.
