Abstract: 1300125 Safety shower J D HUGHES FABRICATIONS Ltd 29 Sept 1971 [1 Oct 1970] 46651/70 Heading A4N [Also in Division A5] A shower for use as an outdoor safety shower e.g. for utilization at chemical plants for workers splashed with corrosive materials, comprises a water outlet 10 arranged to spray water downwardly, a second water outlet 12 mounted beneath said first water outlet and arranged to spray water substantially horizontally, and heating means 40 for heating the water supplied to the two outlets. The shower further comprises an eye-bath assembly 14 supported by an upright member 16 having a base-plate 18 which may be secured to the ground. The member 16 comprises an inner tube 20 preferably formed of mild steel, and an outer jacket 22 which may be formed of a thermoplastic material or of a metal. Between the tube 20 and jacket 22 is a layer 24 of heatinsulating material e.g. an isocyanate foam. Tubes 28, 30 and 32, 34 lead from member 16 to conduct water to water outlet 10 and eye-bath 14 respectively. Electrical resistance heating tapes 40 are wrapped around the tubes 20, 28, 30, 32, 34 and are connected to a junction box 43. An external electrical power supply may be connected to a further junction box 42 from which an indicator light 82 may be supplied. A thermostat 44 mounted in the end of the tube 28, monitors the temperature of the water. Valves 46, 48, 50 are used to control the water flow from the outlets 12, 10 and the eye-bath assembly 14 respectively, the valves 46, 48 being linked for simultaneous operation by a rod 52 pivotally connected to actuating levers 54, 56. A hand control 58 is formed in the rod 52, and an extension 60 of the rod 52 pivotally connected to a platform 62 hinged to the base 18. Thus, the shower may be operated by displacement of the hand control 58 or the platform 62. The extension 60 may be replaced by a flexible link in order to permit hand operation of the shower should the platform become jammed. The valve 50 of the eye-bath is able to be actuated separately to necessitate independent use of the eye-bath assembly, and a filter 76 is provided to remove dirt from the water. In order to ensure adequate drenching of the subject to remove all traces of corrosive materials the water outlets 10, 12 produce angles of spray of 60 degrees and 120 degrees respectively. The water outlets 10, 12 are embedded in insulation 36 in order to prevent freezing of the water.

Title: Recovery of copper as chevreul salt from solutions of copper in sulphurous acid
IPC: C25B1/00
Filed: 1973-10-08
Abstract: 1415113 Electrolytically producing Chevreul salt during extraction of copper from ore ANGLO AMERICAN CORP OF SOUTH AFRICA Ltd 8 Oct 1973 46891/73 Heading C7B Chevreul salt (Cu (CuSO 3 ) 2 .2H 2 O) is electrolytically precipitated from a solution comprising Cu dissolved in H 2 SO 3  by contacting the solution with a pair of electrodes and applying across them a potential difference which is effective to cause the precipitation. The process can be used in extracting Cu from oxidic ores by:- finely grinding the ore and slurrying it with water; passing SO 2  through the slurry to form H 2 SO 3  in situ and leach the ore; separating the leach solution from the ore; electrolytically precipitating Chevreul salt and separating it from the leach solution; and thereafter recovering Cu from the Chevreul salt by roasting it to produce copper oxide, dissolving this in H 2 SO 4  and electrowinning Cu in conventional manner. During the electrolytic precipitation of the Chevreul salt, SO 2  is produced which dissolves in the electrolyte so producing H 2 SO 3  which can be recycled to the leach stage. For the electrolytic precipitation of Chevreul salt, electrodes of Cu, Pt or graphite may be used. Periodic current reversal may be effected to reduce overvoltage problems.

Title: Improvements in or relating to devices for the separation of two mutually adhering widths of material
IPC: B65H41/00
Filed: 1968-10-03
Abstract: 1,206,495. Automatic position control. SEMPERIT OSTERREICHISCH AMERIKANISCHE GUMMIWERKE A.G. Oct.3, 68 [Oct.3, 67], No.46964/68. Heading G3R. In a system for separating two mutually adhering widths of material by means of a roller drawing one sheet away from the other at a shallow angle in the opposite direction, the position of the line of separation is maintained within limits by automatic control of the roller drive in dependence on variations of the position of the line of separation. In Fig.2, two mutually adhering sheets, e.g. of textile or plastic material, forming a web 1, are separated by pulling one, 1a, forwards in the direction 2 and the other 1b, backwards at an acute angle in the direction 6 by a driven roller 11. Shift of the point of separation 3 from the desired position shown varies the extent to which edge 13 obscures light from a source 8 directed towards a photo-cell 9 so that the output of the latter varies the speed of roller 11 to bring the point of separation back to the position shown. Sheet 1b is finally wound up on a roller 4 driven through a slipping clutch. Modifications are described in which (a) the intermediate roller 11 is dispensed with and the speed of roller 4 is automatically controlled (b) two photocells, responsive to light reflected from sheets of different colours on each side of the point of separation, control the speed of winding roller 4 to keep the point of separation between the photo-cells (c) vertical movements of a light or counterbalanced roller pressing on sheet 1b near the point of separation controls the speed of winding roller 4.

Filed: 1967-10-31
Abstract: 1,174,478. Hydrocyclones. N. A. L. WIKDAHL. 31 Oct., 1967, No. 49506/67. Heading B2P. Low density impurities are separated from fibrous material by feeding a suspension of the impure fibrous material to a hydrocyclone under such operating conditions that a light fraction and a heavy fraction are obtained, the proportion of separated low density impurities in the light fraction being greater than that of the fibrous material in that same fraction. The process is applicable to the purification of paper pulp wherein a minor light fraction contains most of the shives and a small proportion of fibrous material and a major heavy fraction contains the bark and a major portion of the fibrous material. In Fig. 1, the suspension of impure fibrous material is fed at C to a hydrocyclone I from which the light fraction is successively passed through hydrocyolones 2, 3 for further separation. The heavy fractions from the various stages are fed to a common outlet D. In a modification, Fig. 2 (not shown), the light fraction from the first cyclone is further separated in two more hydrocyclones in series as in Fig. I, but the heavy fractions from the second and third stages are recirculated to the first and second stages respectively, the heavy fraction from the first stage being discharged separately. In Fig. 3, the light fraction from a first hydrocyclone 7 is passed to a second hydrocyclone 9 from which the heavy fraction is recirculated to the hydrocyclone 7. The heavy fraction from 7 is passed to a hydrocyclone 8 from which the light fraction is recirculated to 7. Fig. 4 (not shown) discloses another arrangement comprising five hydrocyclones. Experimental results are given.
