Title: Arrangement for automatic control of electrodes in smelting furnaces equipped with an even number of electrodes
IPC: H05B7/152
Filed: 1969-02-10
Abstract: 1, 209,133. Automatic control systems for furnaces. ELEKTROKEMISK A/S. Feb. 10, 1969 [Feb. 10, 1968], No. 6992/69. Heading G3R. Electrodes 1, 2, in a smelting furnace are connected in series with each other through the scondary winding of a transformer 3. A balance relay 4 has one coil supplied from current transformer 5, and another coil connected either to the secondary winding of the transformer 3 or to a constant voltage source. Coils H1, H2, are adapted to control movement of the electrodes 1, 2, respectively, the right-hand part of each coil being energized for lowering the associated electrode, whilst the left-hand part is used for raising. A differential relay 9 has voltage coils each connected between its associated electrode and the furnace bottom, this relay transmitting impulses from relay 4 to coils H1, H2, in accordance with the positions of a pair of movable contact arms. If the current detected by the transformer 5 increases, an impulse for raising both electrodes is transmitted to the coils H1, H2, provided that the difference between voltages e1 e2, is within a prescribed limit. If the voltage el is substantially the greater, the impulse is transmitted to the coil H2 only. The system may be applied to a furnace equipped with six electrodes employing three single-phase transformers, or one three-phase transformer, each pair of electrodes being connected in series with one another to a D.C. power supply or a single phase of the A. C. supply. The relay 4 may be replaced by an electronic balance unit. The regulator may transmit pulses to the control circuit intermittently for fixed periods.

The oval lid 3 is carried by an arm 7 which with the integral handle 8 forms a lever pivoted at 9 whereby depression of the handle 8 into its normal position presses and closes the lid 3 up against its sealing: ring 14. The handle 8 is retained in this carrying position by a spring lock 13 and pressing up of the handle 8 lifts the pivot 9 out of its recess 10 so that 7, 8 can be moved round and then lifted to lift out the attached oval lid. The coffee used may be whole or ground up beans.

[Class 83 (ii)] [Also in Group XXXV] A method of making a laminated magnetic core for electromagnetic induction apparatus comprises cutting from a long strip a number of pieces having differing lengths, stacking the pieces against each other in order of their lengths and applying means to retain the pieces in assembled relationship, bending the stacked pieces to form a closed loop having one joint in which loop each piece forms a complete single layer, shaping the loop into a core having a straight winding leg and finally annealing the core to relieve the strains therein. The pieces 14, Fig. 5, have the most favourable magnetic direction parallel to their longitudinal axis, two holes 15, 16 being punched in each strip to accommodate the pins which serve to retain the pieces stacked alternately reversed endwise, Fig. 6. A number of sections such as 6, 7, 8, Fig. 1, of differing widths may be used to form a cruciform core, Fig. 2, to improve the space factor of the window of the associated winding 21, Fig. 11, the sections being held together by straps 10, Figs. 1, 2. The core sections are capable of hinging, so as to open the joints 9, Fig. 11, which are preferably at one end of the central winding leg, in order to assemble the winding 21 thereon. Various alternative embodiments are described showing differing positions of the punched holes in the pieces, differing methods of holding the stacked pieces together to form a cruciform core and differing types of joints, including overlapped butt joints more than one piece thick, scarfe joints and joints having a greater cross-section than elsewhere in the core to reduce the losses therein.
