Abstract: 1407819 Refining nickel sulphide INTERNATIONAL NICKEL CO OF CANADA Ltd 18 Aug 1972 [20 Aug 1971] 38672/72 Heading C1A [Also in Division C7] Impure nickel sulphide containing a chloridizable impurity is refined by chloridizing and extracting the impurity by treatment of the molten impure nickel sulphide while in contact with a molten extractant consisting of at least one chloride of an alkali metal, magnesium or calcium or a mixture of one or more of these chlorides with strontium or barium chloride, with one or both of chlorine or of nickel chloride dissolved in the molten extractant, separating the molten extractant from the purified molten nickel sulphide, treating the molten extractant to precipitate the impurity therefrom and regenerate the molten extractant, and using the purified molten extractant to treat further impure nickel sulphide. The extractant may comprise equal weights of Na and K chlorides and may contain 0À1 to 20% nickel chloride dissolved therein this mixture being contacted with the molten nickel sulphide which may contain 18 to 26% sulphur at a temperature in the range from 750‹ to 900‹ C. on a batch basis or in a continuous counter current process. The separated extractant may be purified by (a) electrolytic treatment to precipitate an alloy of nickel and impurities and gaseous chlorine which may be recycled either by passing through refined nickel sulphide in contact with the molten purified extractant to produce nickel chloride or by direct recycling to the chloridization operation or (b) by treating with magnesium or a magnesium base alloy, e.g. an alloy containing from 6 to 30% nickel or copper to precipitate the chloridized impurity. The so formed magnesium laden extractant may be electrolytically treated to purify the extractant and to recover the Mg and the purified extractant and chlorine so formed may be recycled to the refining step. The refined nickel sulphide may be formed into a turbulent bath and surface blown with a gas containing free oxygen to metallic nickel which is then desulphurized, deoxidized and cast or granulated.

Title: Semiconductor device

Filed: 1961-10-31
Abstract: 926,828. Semi-conductor devices. HUGHES AIRCRAFT CO. Oct. 31, 1961 [Feb. 24, 1961], No. 38992/61. Class 37. The effective inductance of the lead to a semi-conductor body is reduced by arranging for the body and the lead to lie in a cavity in an insulating body, the cavity containing insulating material which covers the body and a small portion of the lead and the rest of the lead being embedded in conducting material filling the cavity. Fig. 4 shows a diode with a tin-coated, phosphor bronze lead wire 14 which is pulse bonded to dome-shaped semi-conductor body 13 bonded to a "Kovar" (Registered Trade Mark) base electrode 11 which is coated with gold containing 1% of zinc or antimony. Base electrode 11 is bonded to alumina ring 12, the ends of which are coated with molybdenummanganese alloy and then gold-plated. An insulating epoxy resin 16 covers body 13 and a minimum length of lead 14 and a silver epoxy conducting resin covers layer 16 and contacts lead 14. The effective length/diameter ratio of lead 14 is thus much reduced to facilitate operation at high frequencies. A gold-plated tantalum cap 18 completes the assembly and provides means for connection to lead 14. Fig. 5 shows a transistor construction of a similar nature except that ceramic bridge 22 provides two separate hole regions each containing one of the electrodes 23 and 24. The semi-conductor may consist of tin doped gallium arsenide, germanium or silicon and polystyrene may be used in place of the epoxy resin. The device may be a tunnel diode, parametric diode, or varactor.

Abstract: 1478122 Radiography EMI Ltd 5 Sept 1974 [17 Aug 1973] 39071/73 Heading H4F A method of examining a plane slice of a body 1 by X- or γ-radiation of the type described in Specification 1,283,915 which utilizes data processing based upon the convolution techniques described in Specification 1,471,531 and which reduces errors due to the body under investigation containing part of one or more organs which are likely to move during the examination, the method including the steps of (a) obtaining, from information derived from at least two different sets of paths (e.g. α and #, Fig. 2), approximate values for the absorption (or transmission) coefficients of the elements of a matrix of elements notionally delineated in the investigated plane slice, (b) using these approximate values to estimate the absorption suffered by the radiation when traversing the body along a different set of paths, e.g. at 45 degrees to the sets of paths α and #, (c) comparing the estimated absorptions with the actual measured absorptions for this different set of paths to obtain an indication of discrepancies therebetween, (d) using these discrepancies to modify the measured absorptions and to up-date the approximate values, and repeating steps (b), (c) and (d) for other different sets of paths. In Fig. 2 the actual absorptions along five paths of each of two orthogonal sets α and # are indicated as P1-P10, and the corresponding convoluted values as P1<SP>1</SP>-P10<SP>1</SP> so that approximate values of the convoluted absorptions coefficients comprise the summed values for the path of each set which traverses the relevant element (as indicated in Fig. 2). The comparison of step (c) may be effected using a pattern recognition device of the kind described in Specification 1,234,941. Although the absorption coefficient values may be obtained using a single source and one or more detectors as in Specification 1,283,915, preferably the two orthogonal sets of absorptions are measured simultaneously using the apparatus of Fig. 1 which includes two sources of radiation 4 and 5 with associated detectors 8 and 10 which are linearly moved to and fro along tracks 6, 7, 9 and 11 between each half degree rotation of turntable member 3 about the body 1, which is preferably located in circular aperture 2 and surrounded by a water bag.
