Title: Dual-Control for Controlling the Liquid Level in a Continuous Casting Mould
IPC: B22D11/18
Filed: 1966-09-08
Abstract: 1,160,886. Automatic level control. UNITED STATES STEEL CORP. Sept.8, 1966 [Sept.21, 1965], No.40233/66. Heading G3R. In a system for automatically maintaining a desired level of molten metal in a continuous casting mould, deviations of level control, proportionally, the speed of pinch rolls withdrawing the casting and, if this speed deviates from a preselected value by more than a predetermined extent, the speed deviations control, proportionally, the rate of pouring of metal into the mould. As described, means detecting the level of molten metal in a continuous casting mould normally automatically control the speed of pinch rolls withdrawing the casting from the mould, but if this speed, as determined by a tachometer generator, varies by more than a predetermined extent from a preselected speed determined by the setting of a manually operated potentiometer, a difference voltage renders one or other of two biased diodes conductive, according to the sense of variation, so that the difference voltage is effective to control a hydraulic system adjusting the stopper of a ladle from which molten metal is poured into the mould. Both control systems, which are similar to systems described in Specification 1, 092, 153, then co-operate to maintain a desired level in the mould. A switch is provided to permit changeover of control of the rate of pour from the difference voltage to a level deviation signal.

Filed: 1970-08-28
Abstract: 1287171 Automatic gain control THOMSON CSF 28 Aug 1970 [29 Aug 1969] 41645/70 Heading H4R [Also in Division G4] In a system in which signals are quantized before transmission signals reaching the maximum quantization level cause the addition of attenuation in the signal path to the quantizer, while signals not exceeding a predetermined quantization level over a predetermined time cause reduction of the attenuation in the signal path to the quantizer. The original signal level is restored at the receiver by an inverse process. As shown in Fig. 1 signals to be transmitted, e.g. by a PCM coder, are fed via a band pass filter 2, a regulating unit, such as a preemphasis circuit 3 and a variable attenuator circuit 4 to a multi-level quantizer 6 feeding a coder 10. Detection of the maximum quantization level causes a signal on line 7 which is applied to step a counter 13 in such a direction as to cause an increase in the attenuation of attenuator 4. Detection of either the maximum or the next to maximum level by quantizer 6 cause energization of a reset circuit 19 which resets a second counter 15 to zero. The second counter is fed with pulses from a clock source 20 and if a predetermined count is reached without the counter 15 being reset a signal is applied, at 14, to counter 13 to cause stepping in a direction to reduce the attenuation of attenuator 4. As applied to a multiplex system the items in box 22 are provided one for each channel with switching devices on the connections 5, 12, 17, and 18, connecting the channel equipments to the common transmitter circuits. The receiver, Fig. 2, operates similarly to the transmitter with detection of the maximum quantization levels 107 causing stepping of attenuation counter 113 in one direction while counter 115 steps the attenuation counter 113 in the other direction unless reset by a quantization level 107 or 108 before reaching the maximum count.

In Fig. 1, the web W passes over an idler roller 3 with a torsioning bond 10; across a splicing table 4; through continuously rotating feed rollers 6, 7 ; into a stationary container 8 which accumulates web for feeding while changing a roll 1; through tension means 19 and thence via idler rollers to feed rollers 17, 18 feeding a machine (not described). A variable speed drive 27 operates feed rollers 6, 7 via a clutch 26 at a higher peripheral speed than that of feed rollers 17, 18 until sufficient web has accumulated in the container 8 to permit changing of the web roll 1 without stopping feed rollers 17, 18. The speeds of the feed rollers are then maintained the same. Upon exhaustion of web roll 1, a loss of tension in the web is detected by a spring pressed arm 29 which operates a micro-switch 28 which in turn disengages the clutch 26. A replacement roll is then fitted and spliced by hand with an adhesive strip to the end of expiring web. The tension means 19 comprises felt, wool or velvet pads applied directly to the web W. In Fig. 3, the web W 1  runs over a splicing table 104 ; through feed rollers 106, 107 normally acting as idler rollers ; directly through tension means 119  similar to 19 of Fig. 1; and over and through dler rollers and a printing device 132 to a friction bond arrangement 134. A spring pressed cam 129 with a roller 154 senses the diameter of the web roll 101. Upon reaching a predetermined diameter, a micro-switch 128 is actuated and starts a reversible motor 136, Fig. 4 (not shown), which drives the feed rollers 106, 107 via a gear train and a one-way clutch 149 at a peripheral speed 10% greater than the friction bond 134. This provides a surplus of web in the reservoir 108 which is used during splicing. A push button switch 137, Fig. 4 (not shown), stops the motor 136, and the expiring roll 101 is replaced and spliced to the end of the expiring web. Further actuation of the switch 137 starts the motor 136 in the opposite direction, and the feed rollers 106, 107 are driven via a modified gear train and a one-way clutch 150 at a peripheral speed 5% less than the friction band 134 until the remaining surplus of web has been used. The motor 136 is then stopped by actuation of the switch 137 so that the feed rollers 106, 107 act as idler rollers.
