Title: Method and device for electrolytic cutting
IPC: B23H7/12
Filed: 1968-04-02
Abstract: In electrolytically cutting a workpiece 1 (e.g. of uranium) parallel flat rings 16a, 16b serve as cathodes and the workpiece as the anode. Electrolyte (e.g. acid) supplied by a nozzle 14 is poured on to the workpiece through the passageway 18 between the rings 16 whilst a protective liquid (e.g. oil) which is immiscible with the electrolyte is poured on each side of the passageway from nozzles 22, 23 thereby forming a film limiting cutting action in the lateral direction. The discs are rotationally driven alternately in one direction and then the other by means of a motor 10. The discs can be moved vertically towards or away from the work by means of a motor 28, pinion 26 and rack 24. This movement may be controlled in dependence on the voltage developed between the discs and workpiece or on the current intensity, the voltage and current being functions of the distance between the discs and workpiece. Thus, the motor 28 can be started and stopped so as to maintain the distance constant. As shown, an element 30, responsive to voltage in the electrolysis circuit, controls startup of the motor 28. Positionally adjustable pointers 31, 32 correspond with maximum and minimum permitted values of the distance between the rings 16 and workpiece 1. When the maximum or minimum values are exceeded the motor 28 is started. In an alternative arrangement, where such control is not used, the discs are moved towards the workpiece at a speed predetermined according to the intended cutting speed. A modified embodiment is illustrated in Figs.2 and 3 (not shown). A motor (52) raises and lowers the discs (16) and a motor (64) rotates them. The positions of protective liquid supply nozzles (22, 23) are adjustable. Circulation and filtering of the protective liquid and separation thereof from electrolyte and similar circulation of electrolyte are referred to.

Title: Apparatus for automatically regulating the anode gap in electrolysis cells
IPC: G05D3/12
Filed: 1968-11-05
Abstract: The position of the anode 52 of an electrolysis cell 5 is automatically regulated to maintain the electro-motive force e of the cell within a predetermined range. As shown the voltage U between the cell terminals 53, 54 is applied to a voltage converter 1 which produces an output kU at terminals 13, 14. A shunt 6 carrying the cell current I supplies a current converter 2 whose output k1I is fed to a potentiometer 3 which is adjusted to produce an output k1k11I equal to kRI, were R is a predetermined value adopted for the internal resistance of the cell. The outputs of members 1, 3 are combined to produce a difference voltage k (U-RI) which is applied to a relay 4 arranged to produce an output when (U-RI) is outside the range set by the limits (e+ a) and (e-a) where a is half the permissible deviation allowed for e. The output of relay 4 is a constant intensity impulse whose polarity is dependent on the direction of deviation of k (U-RI) and which is applied to a D.C. or single phase A.C. electric motor 55 controlling the position of the anode 52. The difference voltage k (U-RI) is also applied (1) to a relay 7 arranged to control the motor 55 when (U-RI) becomes smaller than (e-a1) where a1 considerably exceeds a, the impulse from relay 7 being of greater power or longer duration than that from relay 4 to cause the anode 52 to rise quickly until (U-RI) is once more within the range (2) to a relay 8 via a capacitor 85 which makes relay 8 responsive to rapid fluctuations of k (U-RI), the action of relay 8 being similar to that of relay 7 (3) to a relay 9 which disconnects members 4, 55 if k (U-RI) varies suddenly and is reduced to a value smaller than k (e-a11) where a11 is greater than a1, the regulating action being interrupted for this condition. Switches may be provided to allow the system comprising members 1--4, 7--9 to regulate a number of cells, all using the same reference value R. Separate potentiometer may be provided if a different value is used for each cell. An additional potentiometer may be added to the circuit of converter 1, Fig. 3 (not shown) to minimize the number of switches needed. The operation of the regulating system of the invention in compared with that of a known system measuring a pseudo-resistance of the cell, Fig.2 (not shown).

Title: Electrical transducer
IPC: H04R29/00
Filed: 1969-06-13
Abstract: A transducer having a diaphragm-armature assembly, a magnet polepiece assembly and an associated inductive coil all supported by a frame is made by a method which includes adjusting the magnet-pole assembly to a desired position while frictionally holding it relative to the frame, and maintaining it at a desired position until it is rigidly secured by a solidified fixative, cement, resin or potting compound. A receiver having a central circular armature 23 (Fig. 2) mounted on a circular, inwardly bowed diaphragm 16 secured to a frame 12 (see Fig. 1) of metal or plastics material has a pair of polepieces 14 secured to a permanent magnet 13. Each polepiece 14 is T-shaped (Fig. 6) and comprises a central leg 14b extending through a coil 31, and two bent legs 14d. Pairs of legs 14d are disposed in a U-shaped receptacle (Fig. 7) formed as an integral part of the frame 12. Each receptacle has two opposite leg extensions 45, semi-circular recesses of which engage a U- shaped wire 61. The wire 61 has bowed legs which frictionally engage the polepiece legs 14d and temporarily support the magnet polepiece assembly during the adjustment of the air gap. After adjustment, a fixative 63, preferably in liquid form, is placed in each receptacle and hardened. Instead of the wire 61 there may be used hollow, resilient, plastics tubing (Figs. 9 to 14, not shown), metal strip (Figs. 15 to 17, not shown) or the receptacle walls may be formed with one or more integral projections adapted to frictionally engage the polepiece legs 14d (Figs. 18 to 20, not shown). Adjustment.-The assembly of magnet 13 and polepieces 14 (Fig. 8) is mounted between jaws 71 of a reciprocating ram 73. The receiver frame 12 has the diaphragm 16, armature 23 and coils 31 mounted thereon. The jaws 71 are lowered to bring the polepiece legs 14d into frictional engagement with the wires 61 and a 1000 Hz. signal is applied together with a D.C. bias of approx. 250 ma. to the coils 31. The bias current is of polarity to aid the magnet 13 in attracting the armature 23 until it touches the pole tips 14a. The jaws 71 are then retracted. The D.C. is gradually reduced to zero and then to - 150 ma. A calibrated microphone 81 receives the output signal and feeds a corresponding electrical signal to an oscilloscope 83. The acceptability of the transducer is determined. If necessary, the magnet 13 is partly demagnetized. Finally a signal which sweeps from zero to 4000 Hz. is applied to the coils 31 and if the output signal is satisfactory the leg portions 14d are embedded in fixative.
