Title: Improvements relating to the production of nickel from sulphide ores
IPC: C22B23/02
Filed: 1960-09-12
Abstract: A Ni or Ni/Cu matte substantially free of Fe is autogenously reduced to metal by blowing a stream of oxygen-rich gas on to the surface of the molten matte which is mechanically agitated, until the sulphur content is less than 4%, the blowing is then continued with hot sulphur-free non-oxidising gas the bath being agitated and the temperature being high enough for reaction to occur between the sulphides and oxygen in the melt. The process is carried out is a rotating top blown converter (Fig. 1), oxygen-rich gas being supplied by a water cooled pipe 15 and the exhaust gases passing into flue 18 via opening 17.  Charging is effected through 17 or 16 and the molten metal is tapped either by tilting the furnace or through a taphole 19.  Rotation of the furnace effects agitation of the molten charge and the oxygen rich gas is preferably commercially pure oxygen.  With relatively pure Ni matte blowing may commence at 850  DEG C. but generally a melt temperature of 1350  DEG C. is obtained before blowing starts. The temperature of the melt may be regulated by diluting the oxygen with air or water and when the sulphur content is less than 4%, the oxygen is replaced by a neutral or slightly reducing hot sulphur free gas such as a mixture of a highly combustible <PICT:0960698/C6-C7/1> gas e.g. natural gas or propane with oxygen. With nickel matte the bath temperature in the final blowing should be 1650-1760  DEG C. and lower if copper is present. The melt is finally deoxidised with graphite, Si or Al.  The two stages may be carried out in the same furnace or in different furnaces and the Ni formed contains < 0.05% S.  With iron containing mattes the process is modified by first top blowing the molten matte with oxygen and the iron is slagged off with a flux.  With Ni/Cu mattes the process produces a Ni/Cu alloy but if Ni free of Cu is required the Cu is extracted from the molten matte prior to blowing by treatment with a mixture of sodium sulphide and sodium chloride. Co is removed from a matte by selective oxidation of the Co in a preliminary oxygen blowing while retaining the sulphur content of the melt above 3%. The Co is then slagged off with a flux such as SiO2. Specifications 960,699 and 960,700 are referred to.

Abstract: 643,454. Purifying gases. FASSINA, L., and FASSINA, L. Oct. 22, 1946, Nos. 31393 and 31394. Convention dates, Oct. 26, 1945, and Feb. 27, 1946. [Class 55(ii)] Impurities such as sulphuretted hydrogen are removed from towns gas by passing the cold gas through a moist. granular compound containing a mixture of oxides or hydrates of iron and oxides or hydrates of manganese, the proportion of manganese being less than 10 per cent. The naturally occurring mangano-ferric ore psilomelane, may be used as the basic material. alternatively a ferric ore and a manganese ore may be mixed together. The purifying compound is prepared for use either by granulating the moistened ore directly on a vibrating screen or by forming granules by coating particles of an equal weight of an inert material such as coarse sawdust with the moistened ore in a malaxator. About 3-10 per cent of a dry powder such as lime may be added to keep the granules apart. The impure gas is passed in a cold state through the granular mass which ab-- absorbs the sulphuretted hydrogen. After fouling the material is revivified in the purifier by blowing cold damp air therethrough. The manganese content of the material is kept below 10 per cent to ensure that fouling and revivification temperatures do not exceed 60‹C.

Filed: 1969-06-23
Abstract: 1,212,955. Transistor bi-stable circuit. INTERNATIONAL BUSINESS MACHINES CORP. 23 June, 1969 [11 July, 1968], No. 31560/69. Heading H3T. Each transistor of a cross-coupled bi-stable pair T1, T2 has a load R1, R2 across which a shunt such as a diode D1, D2 is connected, the shunts being non-conductive when the bistable is quiescent in one stable state, and one or both diodes conducting to shunt its load when information is read from or written into the bi-stable. Power dissipation is thus minimized by using low supply voltage 10 and high resistors R1, R2. To read, the word line WL is raised in potential, so that if T1 is on, the increased current flow through R1 and R3 causes D1 to conduct and the emitter e4 to start conducting as the emitter e3 rises in potential. The state of the circuit is thus indicated by current flow from one or other of emitters el, e4 to the respective signal line B0/S0 or B1/S1. To write, the word line is again raised in potential, and the selected signal line B0/S0 is lowered in potential. Both diodes D1, D2 conduct and T1 is turned off, by virtue of the drop in potential at A. T2 is turned on and the change of state is secured by regenerative action.

Abstract: 1477194 Toy sailing boats D HEATH 19 July 1974 32156/74 Heading A6S [Also in Division B7] A toy sailing boat 10 (Fig. 1) has a hull 11, at least one said 12 and a keel 15, the keel being substantially L-, J-, or C-shaped with a downwardly extending section 16 attached to the rear of the hull and a forwardly extending section 17 at the bottom of the downwardly extending section, so that the centre of wind pressure A is positioned forwardly of the centre of water pressure B. Thus in use the boat will always turn downwind. The section 16 is broad in the forward direction to give lateral water resistance, while section 17. is weighted relative to section 16 to provide a low centre of gravity, C of G, for increased rolling stability. Also for improved stability, the bottom of the keel is substantially the same distance below the deck as the top of the topmost sail is above the deck, the length of the hull being in proportion. The keel 15 may be made collapsible (Fig. 3, not shown), the section 16 being pivoted to a fixed attachment to the hull with the section 17 pivoted to the end of section 16, so that the keel can be folded up against the hull where it may be secured by a clip. When the keel is thus folded, the boat will float in shallower water. In another embodiment, a model square ridged ship, the sails (Fig. 4a) which are to be mounted on one mast are cut in one piece from sheet material so that the lower corners of one sail merge with the upper edge of the adjacent lower sail, each sail having an apertured tab by which the sails are mounted on the mast. The boat may be made of wood or plastics material e.g. the hull may be of polystyrene foam, although a heavier material e.g. lead, is used for the section 17 of the keel. The boat may be provided with plates or filaments attached in a vertical plane to the keel, the plates or filaments lying flat in the same plane as the keel when the boat is moving forward but opening outwardly if the keel moves backward in the water so as to restrict such backward movement and dampen any tendency for the boat to pitch.
