Title: Improvements relating to frequency-changing power supply circuits
IPC: H05B41/282
Filed: 1965-10-26
Abstract: 1,127,142. Transistor oscillator circuits. OHIO CRANKSHAFT CO. 26 Oct., 1965 [27 Oct., 1964], No. 45304/65. Heading H3T. [Also in Division H2] A frequency changing arrangement comprises an A.C. source 16 supplying lines 13, 14, between which are connected two transistor multivibrators 28, 28<SP>1</SP> in series with resistors 38, 38a, loads (e.g. fluorescent lamps 10, 11) being connected across these resistors, and diodes 38, 39<SP>1</SP>, 39a, 39a shunting the transistors. In operation during that half-cycle of the supply when the line 13 is positive the upper multivibrator 28 is operative and the lower ends of the loads are directly connected to the line 14 by the diodes 39, 39a. Whilst the multivibrator 28 is operating (at a frequency higher than the supply frequency) each transistor 29, 29a conducts alternately, and high frequency voltage is applied to the two loads, that of the one being complementary to that of the other. The amplitude of these load voltages varies with the input A.C. amplitude. At the end of this half cycle when line 13 becomes negative with respect to 14, the upper multivibrator ceases operation and the lower multivibrator 28<SP>1</SP> starts, and the operation is continuously repeated. Low loss impedances Z are included in series with the lamps 10, 11 and a supply transformer feeds their filaments. The diodes 39, 39<SP>1</SP> are Zener diodes and as such act to protect the transistors against forward voltage surges. Ballast transformers are not required for the lamps. The transistors may be replaced by internally switched solid state devices, e.g. four-layer Shockley diodes.

Abstract: 1331296 Sorting coal RUHRKOHLE AG 23 Sept 1970 [26 Sept 1969] 45369/70 Heading B2H Raw washery coal 1, which may be first de-dusted and deslimed, is fed without previous classification into a jigging machine 2 consisting of compartments 3, 4, 5 arranged in series. In compartment 3 pure waste discharged from a screen plate 3a is delivered into the bottom of the compartment by a discharge device 3b and passes through a discharge 3c into a pure waste bin 18. A small quantity of fines may enter the bottom of the compartment 3 through the screen plate 3a. T'he heavy fraction and the coal of desired particle size pass successively through compartments 4 and 5, pure coal being discharged at an overflow 6 and fed to a pure coal bin 20. The fine heavy fraction passes through screen plates 4a, 5a into the bottom of compartments 4, 5 and the large heavy fraction discharged from the screen plates 4a, 5a is delivered into the bottom of these compartments by discharge devices 4b, 5b. The discharge devices 3b, 4b and 5b may be of the cellular wheel, slide valve or tilting bed type. The fine and large heavy fractions are discharged from compartment 4 on to a classifying screen 7 where the large heavy fraction is removed as screen oversize 9 to the pure waste bin 18. Similarly, the fine and large heavy fractions are discharged from compartment 5 on to a classifying screen 8 where the large heavy fraction is removed as screen oversize to a middlings bin 19. The fine heavy fraction passing through screens 7, 8 are fed to a further two-compartment jigging machine 13 for after-sorting. Fine waste discharged from the first compartment is led to the bin 18, fine middling from the second compartment passes to the bin 19 and fine coal discharged as overflow 16 is directed to the bin 20. Aftersorting may alternatively be carried out in a heavy liquid. The mixture of waste and fines discharged at 3c may be made to pass along (dotted) line 17 to the screen 7 for resorting. Under-screen water may not be fed to the jigging machine to increase the suction effect.

Abstract: 1408308 Mineral mining installations GEWERKSCHAFT EISENHUTTE WESTFALIA 4 Oct 1972 [4 Oct 1971] 45744/72 Heading E1F A mineral mining installation comprises a winning machine 1 driven on an endless chain 3 along a conveyor 11, a sensing means on the conveyor which initiates stopping of the chain when the machine reaches a predetermined position, and a carriage 14 also movable on the conveyor and linked to it via a damping means 10; the carriage being engaged by the machine to check any inertial movement after the chain has been stopped. A magnetic element 4 on the machine actuates a sensing means 5 to stop the chain 3 after a predetermined delay, and any further movement causes a leading edge 8 of the machine to contact a stop member 9 of the carriage. Thereafter the machine moves against the resilient or hydraulic restoring force of the damping means 10 and the carriage runs into a final stop member 17 if all the energy of the machine is not dissapated. As shown the damping means 10 is a piston and cylinder unit-the piston rod 15 articulated to the carriage, and the cylinder 16 connected to the conveyor via a member 25.

In the circuit shown, a motor M drives a generator G producing a three-phase output UVW. One phase is rectified by a controlled rectifier bridge CR and supplies a field winding F. The bridge is controlled by a phase-shifting circuit 10 including a magnetic amplifier powered by the generator output and receiving a reference input 14 and a control input on winding 12. A transformer 16 converts the generator output to a voltage suitable for input to a saturable reactor 22 producing an output current, dependent on the generator voltage, which is rectified by a bridge 34 and fed to the circuit 10 by way of a potentiometer 38. A Zener diode 36 limits the signal, so that excursions into a positive feedback region of the magnetic amplifier characteristic are prevented. The reactor 22 has a main winding 24 and a series auxiliary winding which can be reverse-connected and varied by a switch 28. A resistor 32 is connected across the input terminals of bridge 34 to improve response by compensating for voltage drop across the diodes of the bridge. This resistor also reduces the current loading on the diodes. In modifications, the transformer 16 includes a variable auxiliary secondary winding, Fig. 4 (not shown), and the Zener diode 36 may be replaced by a saturable reactor (40) in parallel with the resistor 32.
