Abstract: 1342822 Solvent extraction of Cu and/or Co values SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 13 Jan 1971 [15 Jan 1970] 1706/71 Heading C1A Copper and/or Co cobalt are extracted from their aqueous ammoniacal solutions at pH 7À0- 9À5 with a solution of a dialkanoylmethane in a hydrocarbon, each alkanoylmethane group is branched in the α position and contains 4-10 carbon atoms. For the extraction of copper the preferred extractant is 0À1 to 4N and preferably 0À25-1N with respect to the dialkanoylmethane, and for cobalt at least 0À5N, preferably 1À5- 3À0N. The most preferred extractant is dipivaloylmethane. In the illustrated process, an ammonical leach solution contains Cu<SP>11</SP>, Co<SP>11</SP>, Ni<SP>11</SP> and (NH 4 ) 2 SO 4  at a pH of about 9 is passed from line 9 through contactor 12 in countercurrent flow to extractant, dipivaloylmethane in kerosene, entering at line 15. A copper rich extract is removed at 20 and after separation of residual aqueous liquor in separator 21 is passed to vessel 25 where it is treated with IN H 2 SO 4  for stripping of Cu values. The acid Cu<SP>11</SP> solution and stripped extractant are separated in 30, the former is removed and the latter recycled to the contactor 12. The copper-depleted liquor leaving contactor 12 at 16, after removal of residual organics at 19 is passed to second contactor 35 wherein it is contacted with a second dipivaloyl methane/kerosene extract. The Co rich extract is removed at 41, separated from residual aqueous liquor in 42 and treated with HCl in 46 and separator 51 to produce cobalt chloride and recycle solvent and the raffinate from 37, after separation of residual organics in 39 in treated for recovery of Ni, e.g. by hydrogen reduction (not shown).

Patent GB-1539931-A (GB)
Title: Method of and apparatus for producing fibre sheets
IPC: B28B1/52
Filed: 1976-01-19
Abstract: In the production of, for example, asbestos cement boards, a felt belt is guided through a deposition box in which an asbestos cement slurry is disposed. A mat is deposited from the slurry onto one side of the felt belt and the mat is sucked onto the felt belt, for which purpose a suction device is present on the other side of the felt belt. In order now to obtain boards of uniform thickness and strength, a cylindrical screen/couching roll arrangement (18, 19) which compacts and dewaters the deposited mat is disposed downstream of the deposition box (6). The suction of the mat takes place by a subatmospheric pressure which is locally variable in the longitudinal direction and/or lateral direction of the felt belt. To this end the suction box is subdivided into individual boxes (8, 9) which are arranged one behind the other in the conveying direction and, if appropriate, one next to the other across the felt belt width. Preferably an adjustable cover screen (10) is arranged in the deposition box (6), such that a flow channel (11) for the asbestos cement slurry is produced between said cover screen (10) and the felt belt (3). This flow channel promotes the desired irregular orientation and uniform density of the asbestos fibres in the mat. <IMAGE>

Abstract: 658,851. Spacing hair fasteners. DEHN, S. G. (Gaylord Products, Inc.). Jan. 27, 1949, No. 2298. [Class 78 (i)] [Also in Group XXII] An apparatus (Fig. 1) for spacing a group of articles, e.g. hair fasteners, includes an inclined rod 23 having a plurality of notches 28 formed in its upper surface, a frame 17 for supporting the rod at its ends, and vibration means 18 for vibrating the frame so as to cause the group of articles straddling the rod to advance downwards along said rod until they rest spaced in sealed positions in the notches. Fig. 1.-Frame 17 is pivoted at its rear at 18a and supported at its front on toothed wheel 18, rotation of which vibrates the frame and causes hair fasteners 27 straddling the smooth upper part of rod 23 to move downwards till they occupy the notches 28 in the rod. The rod 23 is supported on the frame 17 by a notch 24 formed in the rod and by a notch 26 formed in the frame 17. Figs. 4 and 5.-Frame 17 is pivoted at 31 to turn about shaft 32 and carries roller 41 disposed between cams 37. The cams are rotated upon shaft 38 so that rod 23 is given a horizontal vibration which causes the forward displacement and spacing of the fasteners. Alternatively the cams may strike as well as guide the roller so that the rod receives both a vertical and a horizontal vibration and there may be superposed a longitudinal vibration caused by an electromagnetic vibrator. Figs. 8 and 9.-An endless-belt conveyer 51 is carried between pulleys 52 in frame 53 and is inclined across its breadth so that it conveys trays 54 carrying the fastener-supporting rods 23 at an angle. As the tray 54 passes over pivoted plate 58 it receives vibrations therefrom, the plate 58 being vibrated by toothed wheel 61 rotated on shaft 62, and the fasteners are thus spaced along rod 23 whilst being transported on the belt. Fig. 12.-Rod 66 formed with notches is supported on a frame 68 and vibrated by electromagnetic vibrator 69. The rod 66 may also serve as oven rod. The vibratory means may be mechanical or pneumatic and the vibrations may be longitudinal, lateral and vertical in this sequence.
