Abstract: 1524722 Automatic control of current and voltage MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 Sept 1975 [10 Sept 1974(2) 3 Dec 1974(2)] 36695/75 Headings G3R and G3X The power output of a magnetron is controlled by a thyristor switching circuit connected on the primary side of a step-up leakage transformer. The power may be varied by adjusting the switching frequency or the duty cycle. In the arrangement shown in Fig. 6, a magnetron 33 for micro-wave heating is energized from an A.C. source by way of a rectifier bridge 24, resonant circuit 26, 27, thyristor switch 29, transformer 28 and voltage multiplier 31, 32. The filament of the magnetron is also supplied from the A.C. source over a separate transformer. In operation, the anode current of the magnetron is sensed by a resistor 34 connected to a transistor 38 in a bridge circuit with resistors 36, 37, 39. If the current should exceed a pre-set level, the bridge becomes unbalanced and a transistor 40 turns on a transistor 42 which short-circuits firing signals normally supplied to the thyristor 29 by a trigger circuit 43. In an alternative embodiment, Fig. 7 (not shown), the sensed current signal is supplied by way of an LED photo-coupler and varies the supply by controlling the frequency of a multi-vibrator circuit supplying the thyristor firing pulses. The supply may also be controlled in response to measured anode voltage. A further embodiment, Fig. 8 (not shown), includes a photo-coupled sensing circuit responsive to the input voltage produced by the rectifier bridge 24 and operative to control multi-vibrator frequency.

Abstract: 873,968. Centrifugal pumps. WORTHING- TON CORPORATION. Nov. 2, 1959, No. 37083/59. Class 110 (1). In a self-priming centrifugal pump in which the impeller discharges by way of a passage 20 to a discharge chamber 13, priming is effected by recirculation of fluid from the discharge chamber 13 to the impeller chamber 14 through a tube 25. A spring 31 presses the tube 25 inwardly so that a shoulder (not shown) on the tube abuts against a shoulder on the pump casing. This construction permits the use of impellers of different diameters, the tube 25 selected for use with a particular size of impeller being of such size that its leading and trailing edges 27, 28 lie close to the periphery of the impeller. In an alternative construction, the spring 31 is omitted and the tube 25 is located longitudinally by means of a rod having a screw-threaded engagement with the pump casing. This permits adjustment of the clearance between the tube 25 and the impeller to compensate for wear. Specification 836,945 is referred to.

IPC: H05B6/02
Filed: 1962-10-05
Abstract: 1,049,859. Induction heating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 27, 1963 [Oct. 5, 1962], No. 37786/62. Heading H5H. [Also in Division F4] A reciprocating pusher 10 moves a string of billets 1-8 through an induction heating-coil 12, a soaking muff 13 equalizing the temperatures in the different portions of each billet. As billet 1 emerges from the discharge end of induction boost coil 14, it is gripped by pinch rolls 15 which advance the billet at a speed greater than that afforded by the pusher 10. The length of the coil 14 in the travelling direction is less than the length of each billet. Thus, the forward end of each billet is additionally heated by the coil 14, the billet being extracted at the higher speed so that the rear end is not appreciably heated by the boost coil. As the front end of a billet emerges from the boost coil, it strikes a limit switch, which starts the motor driving the rolls 15. For treating billets of different length, a number of limit switches are positioned correspondingly, and a selector renders an appropriate one of the limit switches effective. In another arrangement, the boost coil is positioned in front of the coil 12, and is controlled by a switch box cooperating with the pusher. Limit switches define the period during which the boost coil heats each billet in dependence upon the relationship between the field of the coil 14 and the billet, so that the front end is pre-heated before it enters the main coil 12. The switch box comprises contacts controlling contactors in the circuit of the boost coil, the position of the contacts being adjustable to provide for billets of different length. The induction coils may be of the single-phase or polyphase types, and connected in series or parallel. The boost coil may be supplied through a step-down transformer.
