Abstract: 1,071,439. Semi-conductor switching circuits. BROWN BOVERI & CO. Ltd. Dec. 15, 1965 [Dec. 17, 1964], No. 53192/65. Heading H3T. [Also in Division H2] The current through a load 3 from a D.C. supply 1 is controlled by a power thyristor 4 which is switched on by discharge of a capacitor 8 (charged slowly via members 6, 7) and is switched off by discharge of a capacitor 11 through a series circuit comprising the thyristor 4 and two control thyristors 14, 19. To switch off, the thyristor 14 is fired by discharge of a capacitor 16 and this in turn fires the thyristor 19 to complete the series circuit, conduction ceasing after the discharge of capacitor 11 due to the magnitude of resistors 12, 13. Thyristor 4 may be automatically switched off upon overload by provision of a second firing circuit for the control electrode of thyristor 14, this circuit comprising a load-current-carrying resistor (22), a resistor (23), a diode (24b) and a Zener diode (25), Fig. 2 (not shown). The load 3 may comprise the armature (27) of a separatelyexcited D.C. motor which can be supplied with pulses of adjustable length and/or frequency by triggering the thyristors 4, 14 in accordance with a predetermined firing programme, the motor armature being in series with an inductance (26) for smoothing and transient suppression purposes, Fig. 3 (not shown).

Title: Control of furnaces

Filed: 1970-11-26
Abstract: 1331116 Controlling reheating furnaces GENERAL ELECTRIC CO 26 Nov 1970 [15 Dec 1969] 56362/70 Heading F4B The heat input to at least one zone of a slab reheating furnace is controlled by calculating the temperature of each slab in the zone from its dimensions, thermal properties, location and previous history, and the gas temperature in the zone, comparing this with a desired slab temperature at that location to produce a temperature deviation, obtaining a performance index as a function of all the deviations in the zone and adjusting the heat input as a function of the performance index. The temperature deviation of each slab may be weighted in accordance with the location of the slab so that the deviation of a slab near the zone exit has more effect than that of a slab near the zone entry in determining the performance index. The arrangement is such that allowances are made for hold ups, and the additional heat requirement at decalescenoe, and the required temperature change is held between set values. The temperature of a slab is not allowed to rise above that at which it starts to melt. Pyrometers measure the actual surface temperature of the slabs, and a factor representing a thermal property of the slab in the equation used to calculate the slab temperature from the gas temperature at each end of the zone is modified to compensate for errors in the calculated temperature.
