Patent GB-691115-A (GB)
Title: Improvements in or relating to the recovery of copper from copperbearing mixtures
IPC: C01G3/00
Filed: 1950-05-24
Abstract: Copper is extracted from copper-bearing materials, at least part of which comprises iron and copper sulphides, and which may have been concentrated, by treating with a liquor comprising sulphuric acid and copper ions, and say 2-15 per cent ferric sulphate so that substantially all the copper is precipitated as sulphide, filtering and treating the press cake to produce a copper salt solution, e.g. by oxidation with oxygen and/or air in the presence of a sulphuric acid-ferric sulphate solution at 300-750 lbs./sq in. and at 100-325 DEG C.  The copper and ferric sulphate solution produced is filtered if necessary and cooled, and copper sulphate crystallized, the molten liquor being returned partly to the oxidation stage, and partly to the copper sulphite-producing stage.  The crystals dissolved, and the solution (or even the solution from the oxidation stage if sufficiently pure) is treated with copper metal, e.g. cement or scrap copper, or copper from the present process, [Group II], and carbon monoxide, e.g. as in Specification 691,113 to reduce the salt to the cuprous condition.  The press cake obtained on filtration is returned to the copper sulphide-production stage, or, if desired, to the reducing stage, and the cuprous salt solution is then treated with carbon monoxide at 100-150 lbs./sq. in. and 200-275 DEG C. to precipitate say 60-70 per cent of the available copper.  The solution remaining is returned to the copper sulphide-producing stage, or in cases where the iron content of the ore treated is lower, to the oxidation stage, One concentrates with a much higher iron content are submitted to a preliminary oxidation, carried out as before, and the filtrate is used to treat additional concentrate in the presence of added copper ions.  The filtrate from the copper sulphide-production stage may contain zinc, nickel and cobalt.

Title: Sliding clasp fastener and method for attaching the same to a cloth article
IPC: A41H37/00
Filed: 1959-04-16
Abstract: 897,325. Sliding clasp fasteners. CRYSTAL, P. E. April 16, 1959 [June 6, 1958; July 30, 1958], No. 13027/59. Class 44. A sliding clasp fastener comprises a pair of tapes 12, 14 the innermost edges of said tapes being welted for the entire length of the tapes, mating fastener elements 16 secured to said welts on each of said tapes, a slider 28, bridging means 24 securely joining said tapes together at the lowermost portion of said tapes and an element free gap 26 between said bridging means and the lowermost elements carried by said tapes and said gap having a length appreciably greater than the length of the slider with said slider being movable along the welts in the said gap and along said fastener elements. As shown the bridging means is a bar tack but a clasp can be used if desired. Each of the tapes has a top stop 22 consisting of a plurality of non-mating nesting elements. The fastener is mounted on adjacent flaps 32, 42 of a cloth article by firstly applying a line of stitching 30 to join the tape 12 to the flap 32 with the slider in the gap adjacent the bar tack or clip; secondly by joining the tape 14 to the flap 42 by a second line of stitching 52. The lines of stitching are placed as closely as possible to the elements 16 by tilting the elements through an angle of 90 degrees before stitching so that when the elements are tilted into their original position they cover the lines of stitching. After the stitching has been finished the slider is moved on to the elements 16 and the bottommost portion of the tapes are cut along a line extending through the gap 28 a sufficient distance below the bottommost elements to allow room for a bottom stop. The seams 48 and 50 which join the flaps 32 and 42 together above and below the fastener are then extended to the top stop and bottommost elements so that the fastener presents the appearance of a seam which is continuous with and collinear to the seams 48 and 50 and a bottom stop is then applied to the welts of the tapes 12 and 14 adjacent the bottommost elements 16a.

Title: Borehole drilling system
IPC: E21B44/00
Filed: 1962-04-06
Abstract: 950,031. Boring earth &c. JERSEY PRODUCTION RESEARCH CO. April 6, 1962 [May 1, 1961], No. 13430/62. Heading E1F. In a well boring apparatus members engage the wall of the well and apply an upward thrust thereto which thrust is reacted by the bit. A drill string 12 (Fig. 1) carries an arbor 14 which in turn carries bit 18. Rotatably mounted on the arbor is a housing 22 which has ports 28 containing rams 30 bonded to the wall of the ports by elastic collars 32. The outer faces 36 of the rams are inclined and slidably carry wedges 34. Drilling fluid from the arbor bore 56 may flow through ducts 64, 66 to urge the rams outwardly so that the wedges engage the wall with an upward thrust, and fluid from the inner face of the rams may flow through duct 62 to discharge into the well. In the position of the arbor shown the wedges of thrust units 60B, 60D, 60F, 60H are in engagement with the well wall, but as the string and arbor are rotated through 180 degrees these wedges are retracted and the wedges of units 60A, 60C, 60E, 60G, 60J are engaged with the wall. During rotation of the arbor and bit and supply of drilling fluid the continuous upward thrust on the wall developed by the wedges forces the arbor and bit downwardly to continue boring the well. In the modification shown in Fig. 5 the housing 90 is rotated with the arbor 84 by contact between friction plates 120, 122 mounted on the arbor and housing respectively. Gaseous or liquid fluid flows from the arbor bore 86 through duct 106 into annulus 102 above a piston 98 on the arbor to force resiliently mounted shoes 112 on the housing into engagement with the well wall and to bring the plates 120, 122 into engagement. The rotation of the arbor rotates the housing so that runners 116 on the shoes force the housing and bit downwardly. The bit may include means to reciprocate it in response to the flow of drilling fluid or the rotation of the string.

Title: Improvements in or relating to the manufacture of flat grids for high frequency electric discharge tubes

Abstract: 689,947. Making grids for thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 12, 1951 [June 15, 1950], No. 13902/51. Classes 83 (ii) and 83 (iv). [Also in Group XL (a)] In winding a flat grid for an electron discharge tube, two bevelled frames 1 and 4 are placed backto-back to constitute a former, and the wire 2 wound on; the wire is then soldered to the frames and the portions 6 cut away, leaving two flat grids. Because of the bevelled frame edges 3, 5, the part of the wires between the planar grid portions bear on sharp edges only, instead of a continuous thickness; this reduces the possibility of slight irregularities in the diameter of very fine wires causing the wire to tilt as it passes across the side of the former, and so produce divergencies in pitch. In Fig. 6, the grid frames 9 and 10 are separate from the winding former 8, and may be slid into grooves therein and clamped in position, before or after winding the grids. The former may be of triangular or polygonal section, enabling three or more grids to be wound at once, Figs. 8 and 9 (not shown). The technique is suitable for wire of less than 25Á diameter, with a winding pitch of less than 50 Á.

Abstract: 886,247. Determining physical qualities by electrical tests. AVIATION, MINISTER OF. July 28, 1959 [May 2, 1958], No. 14014/58. Class 37. Cracks or flaws in a metal structure are tested for by associating during manufacture of the structure a coil of wire with each point which is to be periodically tested on the structure and making comparative measurements of the impedance of the coil at a situation which is easy of access. The Figure shows a structure comprising two girders 1, 2 bolted together by bolts 3 beneath the heads of which are located peripherally recessed washers 4 each carrying coils such as 5. The coils are connected individually by conductors 5a, 5b, &c. to a point of easy access relative to the structure where connections are made to a terminal board 15. The apparent impedance of the coils is measured in pairs by using them respectively as two arms of a portable A.C. impedance bridge, Fig. 2 (not shown) and the settings of the bridge recorded. This process is repeated periodically, any change in the settings of the bridge being indicative of a flaw or crack in the structure at the related point.
