Title: Improvements relating to saturable core reactance devices
Inventor: KELSALL RICHARD HOPE
IPC: H02M7/06
Filed: 1954-01-12
Abstract: 753,356. Magnetic amplifiers. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 12, 1955 [Jan. 12, 1954], No. 890/54. Class 40 (4). In a saturable core reactance circuit arrangement having two or more cores with output windings (1, 2) thereon connected via respecivet load rectifiers (5, 6) for energizing a load circuit (7) during alternate half-cycles of current in each winding, a current controller (9) is connected on the one hand to the sides of the load rectifiers (5, 6) adjacent the load (7) and on the other hand to the other sides of the load rectifiers (5, 6), respectively, via respective isolating rectifiers (12, 13) which each allow current to flow through the current controller (9) in a path parallel to the associated load rectifier during the non-conducting half-cycles of the associated load rectifier. As shown the current controller is a pentode valve. 9 operating with constant screen-grid voltage and having its control grid connected by conductors 14 to the control voltage source. Variation of the control voltage varies the effective resistance of the valve 9 and hence that of the paths through the valve 9 and the isolating rectifiers 12, 13, in shunt with the load rectifiers 5, 6, respectively, thus varying the point in the alternating current cycle at which the cores (not shown) of windings 1, 2 become saturated. The load rectifiers 5, 6 must be of sufficient capacity to carry the load current but the isolating rectifiers carry only the current of valve 9 (viz. the magnetization current of the cores) and can therefore be of low capacity. As the flow of magnetization current in the shunt paths is controlled in each half-cycle, an approximately constant delay, of less than one cycle of the supply frequency, exists in the response of the load current to changes in the control voltage. The direct current in the load can be arranged to fall to zero or even to a small reverse value by appropriate variation of the control voltage, thus giving a greater effective range of load current than that of the conventional magnetic amplifier. In the arrangement shown the full voltage of the winding 3 is not obtained across the windings 1, 2 because of the anode-to-cathode voltage drop required across the valve 9 in order that the latter may pass the magnetization current. Two modifications are described to overcome this, in one of which (Fig. 2, not shown) the centre-tapped secondary winding of an auxiliary transformer connected to the A.C. supply is connected between the rectifiers 12 and 13, the centre-tap being connected to the anode of valve 9 and the winding being so phased as to add its voltage in the circuits of rectifiers 12 and 13 to that of winding 3 so as to provide an extra voltage sufficient to provide the anode-to-cathode voltage drop in the valve. In the second (Fig. 3, not shown), the rectifiers 12 and 13 are connected to tapping points on windings 1 and 2, respectively, instead of to their ends. A three-phase embodiment is also described.

The manufacture of the photomagneic recording medium usable in the form of a film or tape is thus made possible with the higher productivity than in the prior art in which the thin magnetic film is formed on each sheet of hard substrates of glass, etc. If the substrate having >=70 deg.C glass transition temp. is used, the recording medium having much better surface characteristic is obtd. The hard photomagnetic recording disc may be obtd. by cutting out the substrate into a disc shape and sticking the above-mentioned film between two sheets of the hard discs.

Filed: 1982-01-06
Abstract: PURPOSE:To eliminate strains owing to bulging, etc. and to cast a defect-free ingot continuously by acting large compressive force upon the ingot with upper stream side rolls as thrusting driving forces and lower stream side rolls as braking driving forces. CONSTITUTION:When the preceding end of an ingot is sandwiched by driving rolls 2 in an initial period of casting until the preceding end of the ingot arrives at an unbending point UPB, the rolls 2 are operated as braking drives and compressive forces are applied upon the ingot by the braking forces and the thrusting forces of driving rolls 1. Thereafter, rolls 3-9 are operated successively as braking drives and upper stream side rolls as thrusting drives, whereby the ingot is guided. When the preceding end of the ingot passes the point UBP, driving rolls 10-18 on the down stream side are operated successively as braking drives and compressive forces are acted upon the ingot by the braking forces and the combined thrusting forces of upper stream side rolls 1-9. In the end period of the casting, the combined braking forces on the down stream side are decreased in synchronization with the decrease in the combined thrusting forces upon passing of the succeeding end of the ingot through the rolls of thrusting drives, whereby the ingot is guided.
