Title: An electrolytic process for the purification of metals and apparatus therefor
Inventor: NEAL WALTER THOMAS LONGCROFT
IPC: C25C1/06
Filed: 1956-05-22
Abstract: 820,172. Electrodialysis. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 17, 1957 [May 22, 1956], No. 15826/56. Class 41. An electrolytic process for freeing a metal, e.g. iron, from a non-metallic impurity, e.g. sulphur, which forms anions under the conditions of electrolysis, comprises electrolysing an aqueous solution of a watersoluble salt of the metal, e.g. ferrous chloride, in a cell having an anode of the metal to be purified and being divided by a cation exchange resin membrane 3 which separates the anolyte from the catholyte, which contains none of the impurity. A line of cathodes 1, each rotatable about its longitudinal axis, is located in a compartment C separated by the membranes 3 from anode compartments A, a chamber 5, through which cooling water is passed, being disposed outside the compartments A. Catholyte enters at 8 and leaves at 7, being circulated by a pump through a heatexchanger, an apertured partition 6 dividing the outlet 7 from the rest of the compartment C. A metered proportion of catholyte is withdrawn at 9 and passed to an electrically-heated boiler to drive off some water, the concentrated catholyte being then passed either to the heatexchanger for re-delivery to the catholyte, or directly to the catholyte by injection at 11. In a modification, one anode compartment A only is employed, an anionic exchange resin membrane separating the side of compartment A remote from the membrane 3 from a secondary anode compartment containing dilute aqueous hydrochloric acid, by which means chloride ions which migrate to the anolyte through the membrane 3 are removed from the anolyte. The secondary anode may be carbon or iridium. In operation, substantially sulphur-free iron is deposited on the cathodes 1, water migrating to the catholyte, and chloride ions to the anolyte, which thus becomes more concentrated. A 10% solution of hydrochloric acid is added to the catholyte, and water, e.g. in the form of a 2% solution of hydrochloric acid, to the anolyte to maintain the ferrous chloride concentration, e.g. at 80 to 100 gms. iron per litre. In one example, the cathodes are two pure iron rods rotated at 200 r.p.m., the membrane 3 being polyethylene foil incorporating minute particles of a cationexchange resin, e.g. sulphonated polystyrene. A current of 5 amps. at 5 volts was passed, the temperature being kept at 30‹ to 35‹ C. A complexing agent, e.g. a cyanide, oxalate or tartarate may be added to the electrolyte, to mitigate " treeing," or the electrolyte may be vigorously stirred, e.g. by the rotating cathodes and by the rotating cathodes and by the circulation of the electrolyte.

Title: Device for multiplying two quantities represented by alternating currents at the same frequency
IPC: G01R21/08
Filed: 1966-04-12
Abstract: 1,147,022. Power measurement. G. REHM. April 12, 1966 [April 12, 1965], No.15904/66. Heading G1U. [Also in Division G4] In a power measuring arrangement using a Hall plate but which remains unaffected by disturbing influences such as temperature changes, an alternating current i 1  proportional to a load current energizes the field winding 1 of the Hall plate 3 and a current from transformer 6 excited by the load voltage U energizes the input of the Hall plate. The field of winding 1 is superimposed on that of a winding 2 energized by a constant direct current i 2  and the input current is superimposed on a variable direct current i 3  from an adjustable source 7 in series with measuring instrument 8. The adjustable source is controlled via a variable feedback amplifier-oscillator 10 by the deflection of an instrument 9 responsive to the direct current component of the Hall plate output, which comprises a current proportional to the D.C. component of U.i 1  and an opposing current proportional to i 2  i 3 . The system operates to establish a balance where the instrument 9 is undeflected, and since i 2  is constant, i 3  is proportional to the D. C. component of U. i 1 . The latter represents the active power in the load, so that i 3  is proportional to U.i 1  cos #, where cos # is power factor. Current i 3  may be a train of direct current pulses whose number is adjustable in proportion to the product U.i 1  and current i 2  may be variable to adjust the transformation ratio of the device.

Fig. 1 is a plan view of a machine tool slide 10 and its bed 12 in which play in the runway is taken up by two series of interdigitated wedge elements 13a, 13b on which lengthwise pressure is applied by screws 14; the faces of the wedge elements 13a over which the sliding motion occurs are made considerably longer than those of the other elements 13b. The arrangement thus serves as an adjusting gib. Fig. 5 shows a spring 15 applying the pressure through a dog 16 but with the pressure released, as on the return movement of the slide 10, by hydraulic fluid admitted to space 18 to act on a piston face 17 of the dog. The flank angles of the wedge may differ so as 'to give a reduced wedging effect on the return motion of the slide. With V-grooves in the bed the wedges are of triangular cross section, Fig. 3 (not shown) .

Abstract: 596,573. Fish-dressing machines. FISADCO, Ltd., and FREEMAN, P. Aug. 29, 1944, No. 16410. [Class 28 (ii)] Herrings &c. which are clamped at the tail and held against the vertical face of a moving carrier surface (on a drum), are prevented from tending. to drop or sag down by providing needles on the carrier surface on which the fish are impaled. The fish which are received from the pockets of a horizontal rotary feed table are clamped by their tail clamps 2 against the horizontal surface of the drum 1. During the rotation of the drum, the fish belly is swung in contact with the V-shaped vertical face or edge 3 of the drum 1. The fish then passes through the box 4 and guide 5 to a disc knife 6 which cuts into the back just under the backbone. The fish then opens out and is forced home on to rows of pins or needles 7, 8, Fig. 2, by means of a pivoted tongue 9 urged towards the drum 1 by a spring 10. The fish is then carried to a gill-removing tool 11 which operates as described in Specification 488,159, and then to a rotary brush 13 to remove the entrails as described in Specification 462,526. The fish then passes to a rotary stone wheel 15 which opens and cleans the blood sac. The fish is then prised off the needles by a fixed pivot tongue 16 with two tapering fingers 17, 18 engaging behind the fish and being urged by a spring 21 against the drum. The gap 19 allows the tail to pass through while slots 22, 23 clear the needles. The prising-off device may be made to move laterally of the fish, such device being described in Specification 596,574. Alternatively, the needles 25, 26 may project through and be withdrawn through holes in the drum surface 3 by a cam groove 35 and levers, Fig. 5. The top needles are longer to receive the thicker top half of the fish when split open from the back.
