Title: Improved method of extracting non-ferrous metals from metal bearing material
IPC: C22B23/02
Filed: 1958-11-03
Abstract: In the extraction of non-ferrous metal values particularly of Ni, Co, or Cu from materials containing them by means of an oxidative sulphate leach, the sulphur content of the initial material is adjusted and the mixture is smelted to form a matte having a sulphur content to produce, after oxidation, an amount of sulphate ion greater than, and up to 100% in excess of, the amount required to combine with non-ferrous metal values; the so obtained matte is then ground to a particle size of from 0.417 to 0.043 mm. and reacted with an aqueous sulphuric acid solution in the presence of a free oxygen containing gas at a temperature from 90 to 180 DEG C. until the non-ferrous metal values have dissolved. Oxygen partial pressures from 0.5 to 7 atmospheres are preferred, or if air is used a total pressure from 5 to 9 atmospheres and a temperature from 120 to 150 DEG C. is suitable. The leach solution should contain 0.05% sulphuric acid at least.  According to a typical example a ferro-nickel-cobalt alloy was smelted in a carbon are furnace with nickel sulphide to form a matte containing the required amount of sulphur.  Pyrites may be similarly employed.  The matte obtained was ground and leached.

Title: Multi-container packaging apparatus and method
Inventor: SCHLEICHER ALLEN KLEIBER
IPC: B65D71/00
Filed: 1963-09-06
Abstract: 1,049,429. Packaging machines; packages. ST. REGIS PAPER CO. Sept. 6, 1963, No. 35350/63. Heading B8C. In a method of packaging a group of containers, e.g. bottles, in a wrap-around precreased blank having portions for partially enclosing the ends of the package to assist in retaining the containers, the portions being a pair of flaps extending along and integral with the ends of the base and side panels, the contents are placed on the flat blank, the flaps are folded up through 90 degrees, and the flap portion integral with either the side panels or the base folded further through a greater angle as the side panels are folded up relative to the base, whereby gussets are formed between the flap portions to be trapped between the panels and the containers. In the package shown formed from the blank 1, Fig. 7, container separator tabs 61, 63 are raised from a base panel 2 and containers 3 placed therebetween. Flaps 10, 11 are folded perpendicular to panel 2 to form end pieces, and flaps 12, 13 and 14, 15 are folded flat against panels 4 and 5 respectively as the latter are folded upwardly, so holding flaps 12-15 against the containers and forming gussets at 49, 50, 53, 54. Flaps 23 and 30 are folded over one row of containers so that cups 31 enter apertures 27, and panel 35 is inserted between the rows. Flaps 24, 38 and 41 are then folded over the containers and tabs 44 inserted in holes 45 to close the package, with caps 31 engaging slots 42, 43. The end flaps 10 and 11 may be discontinuous (not shown). In apparatus for forming the packages the blanks are fed singly from a magazine by endless chains 58, Fig. 1, and have the tabs 61, 63 raised before passing on to flights 78, 79, and between spacers 81, 82 of a conveyer 70, Fig.6. Groups of six containers are fed on to the blank between spacers 81, 82 from conveyers 67, the spacers serving to check the flow from the conveyers between the depositing of each group, and cam-operated folding plates 83 lift to fold the leading and trailing flaps 12, 10, 14 and 13, 11, 15 respectively, of adjacent blanks vertically. Ploughs 90, Figs. 1, 8 and 10, androtating discs 93, fold flaps 12-15 beyond the right-angle position and the side panels 4, 5 are folded upwardly by ploughs 91. They are then held vertical between chains 106 whilst a plough 108 folds over top panels 23, 33, and tucks panel 35 between the rows and a plough 109 folds over panels 24, 38 and 41. A device 110 inserts tabs 44 in holes 45 to complete the package. In a second embodiment (not shown) the containers are laid on flaps 4 and 5 before these are raised to the vertical position and in this case flaps 12-15 retain the containers whilst flaps 10 and 11 and the gussets lie flat against the base panel. In a further embodiment the blank may be applied on top of a group of containers and folded downwards about them. Flaps similar to flaps 10 and 11 may be included depending from the top panel of the package.

Title: Improvements in and relating to Transistors
IPC: H01L29/00
Filed: 1966-08-08
Abstract: 1,154,856. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1966 [23 Aug., 1965], No. 35363/66. Heading H1K. The switching time of a transistor is reduced by selecting the thickness of a high resistivity epitaxial collector region between the base region and a low resistivity sub-collector region to be substantially equal to the thickness of the depletion layer. This reduces the volume of the high resistivity collector region in which minority carriers are stored, thus reducing the carrier storage time. As shown, Fig. 2, the transistor comprises an N+ type sub-collector region 10A on which is provided an N- type epitaxial collector region 12A into which are diffused base region 14A and emitter region 16A. The distance between the sub-collector region 10A and the base-collector junction 19A is selected so that at the desired operating voltage the depletion layer fills the collector region 12A. The minority carriers are stored in the region 24A but since this is in the low resistivity sub-collector region 10A they have a low storage time. A transistor is produced by epitaxially growing an N- type layer of silicon doped with phosphorus on an N+ type substrate of silicon doped with antimony. The wafer is oxidized and photo-masked and a P- type base region is produced using a "boron-capsule" technique followed by an oxidation drive-in. The oxide layer is removed from the lower face of the substrate using a blast of nitrogen-propelled alumina, and gold is vapour deposited, alloyed and diffused-in, to reduce the minority carrier lifetime. The wafer is then photomasked and phosphorus is diffused-in to form an N- type emitter region. The contact areas are exposed and a layer of aluminium is evaporated over the surface and selectively removed to produce the required electrodes which are then alloyed to the wafer. The collector region of the resulting device has a thickness of 0À1 mils, an impurity concentration of 8 x 10<SP>14</SP> atoms. cm<SP>-3</SP>., and a resistivity of 6 ohm cm.

Abstract: 623,772. Spray burners. BENDIX AVIATION CORPORATION. Nov. 28, 1946, No. 35372. Convention date, Jan. 9. [Classes 75(i) and 75(iii)] [Also in Groups XII and XXVI] A burner in which a main spray nozzle discharges full into a burner chamber comprises a vaporizing surface against which the spray impinges and which is heated by a separate auxiliary nozzle. The main burner nozzles 51, Fig. 3, of a jet-turbine engine are disposed in a series of annularly arranged cups 42 the walls of which provide vaporizing surfaces for the main fuel spray and are heated by the flames from pilot nozzles 53 arranged alternately with the main nozzles 51, the cups 42 being provided with fins 50 to assist the heating. Fuel is supplied to the nozzles 51, 53 through a conduit 62, Fig. 6, a metering device R, and a valve chamber 58. At low pressures fuel is supplied only to the pilot nozzles 53 through a conduit 54, but when the fuel pressure exceeds a certain value it acts upon a spring pressed diaphragm 60 to open a valve 55 to admit fuel to the main nozzles 51 through a conduit 52. The valve 55 may be double acting to cut off the fuel to the pilot nozzles 53 when the main nozzles become active, or the latter operation may be effected by a thermostatically controlled valve. The pilot burners are ignited by sparking devices, and when the valve 55 opens the main burners are ignited by the penetration of the pilot flames through apertures 64 in the cups 42. The nozzles 51, 53 are mounted on a back plate 40, Fig. 1, in the breech section 30 of the combustion chamber formed between annular shells 31, 33 provided with air inlet holes 32, 321 and 34, 34<SP>1</SP>, respectively, and enclosed by annular jackets 35, 36 of stepped formation having calibrated air inlet holes 37, 37<SP>1</SP>, 37<SP>11</SP> and 38, 38<SP>1</SP>, 38<SP>11</SP>, respectively. The air compressor 18 supplies air through the calibrated openings to the combustion chamber in strata of graduated velocities with the stratum of lowest velocity in the immediate region of the cups 42, the velocities increasing progressively outwardly of the combustion chamber. To prevent overheating of or carbon formation on the tips of the nozzles 51 air is also passed through holes 48 in the backing plate 40 into chambers 47 where its velocity is reduced and from which it flows through openings 49 and around the tips of the nozzles 51. Specification 608,031 is referred to.
