Title: Method and apparatus for indicating anode positions
IPC: C25C3/20
Filed: 1965-02-01
Abstract: In the electrolytic reduction of fused salts, e.g. in the production of aluminium from a melt of cryolite and alumina, by applying a D.C. voltage between the cathode and an anode comprising separately adjustable carbons, alternating voltage amplitude variations within a frequency range up to 20 c/s caused by one or more carbons being closer to the cathode than the others are detected and the said one or more carbons are then moved away from the cathode to reduce the voltage variations.  Typically in addition to the expanded scale D.C. voltmeter and lamp connected across the cell for indicating the condition of the cell under steady conditions and also when anode effect occurs, there is connected in parallel across the cell an amplifier integrating circuit including a low-pass filter, the circuit converting the alternating voltage to an output current in milliamps proportional to the voltage amplitude in the chosen frequency range.  This output current is measured by an expanded scale ammeter which is arranged when a selected value is exceeded to turn on an indicator light, warning of need for adjustment.

Title: Electrical remote indicating systems
IPC: G01S1/02
Filed: 1942-04-03
Abstract: 580,483. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., and MYNALL, D. J. April 3, 1942, No. 4510. [Class 40 (v)] [Also in Groups XXXV and XXXVIII] Apparatus for indicating the angular position of a rotatable member comprises a coil fixed with respect to a datum position and a moving coil fixed with respect to the member, alternating or pulsating current being applied to one of the coils and the current induced in the other coil being used to deflect the beam of a cathode-ray tube the beam of which is suppressed except when it would assume the maximum deflection position corresponding to the position of the member. Specification 580,482 is referred to in the Provisional Specification. In the arrangement shown in Fig. 1, coils 12 and 14 are coupled to the universally rotatable member of an aerial system so as to receive angular displacements corresponding to its movement in azimuth and elevation respectively and A.C. from oscillator valve V1 is induced correspondingly therein from the fixed windings 11, 13. The variable output of the coils 12, 14 is applied to the respective deflecting plates 15, 16 of a cathode ray tube 10 over tapped transformers 17 which enable the scale of deflection to be varied. In order to suppress the beam except during the extreme peaks of the A.C. when the beam would be fully deflected, a part of the ouput from V1 is delayed in network 24 and applied to the suppressor grid of a pentode V2 the output of which thus comprises square topped pulses a, Fig. 3, which are differentiated as at b by coupling R1, C1 and subsequently, shaped as at c by a rectifier D and coupling R2, C2, the square positive peaks which coincide with the positive peaks of the alternating current, being applied between the grid and cathode of the C.R. tube to remove a normal paralyzing negative bias. When pulsating current is applied to the coils, the same current may be used to release the beam. The following arrangements are used for stabilizing the outputs of valves V1, V2 against variation of supply voltage and component valves. The screen grids are fed over common resistance R3 so that if the average anode current of V2 varies the amplitude of the output of V1 varies in opposite sense. The back coupling coils 20 of the oscillator are also connected to rectifier V3 the output of which normally balances a negative voltage from 25. Increase of amplitude in the output of V1 causes positive potential to appear at 26 which is connected to the control grid of V2 the average anode current of which is thus increased with results as stated above.

Filed: 1973-05-31
Abstract: 1440452 Steering by differential braking KOMATSU SEISAKUSHO KK 31 May 1973 [31 May 1972 (2)] 04812/76 Divided out of 1440451 Heading B7H In a brake steering mechanism for a manually and remotely controllable tractor or bulldozer having manual levers 1 on the right and left sides of the vehicle, movement of a lever 1 in the direction indicated causes disengagement of a clutch via lever 4 to disengage the drive to the associated side of the vehicle, and causes spring loaded rod 18 to move into contact with piston 17 to seal a vent passage 16 therein and to transmit the manual force to a brake lever 20. Sealing of the vent 16 allows hydraulic pressure fluid delivered through line 21 to supplement the manual force, whereby braking is effected on one side to cause the vehicle to turn. Remote operation is effected by remotely operating a change-over valve to cause compressed air to be delivered to cylinder 5 to move the lever 1 in the appropriate direction. Moreover, compressed air is delivered through port 30 of pressure-control valve 22 to reduce the spring loading on'valve closure member 25 and thereby cause the valve to reduce the pressure of the hydraulic fluid acting on piston 17 so that, with compressed air supplied to a cylinder 12, the braking is gradual and the vehicle is not turned too quickly. However, compressed air delivery to the cylinder 12 may be cut off so that the force of spring 14 supplements the force exerted by the hydraulic fluid and causes more rapid turning of the vehicle.

Title: Automatic control system for continuous strip mill
IPC: B21B37/16
Filed: 1959-02-11
Abstract: 898,613. Automatic control systems for rolling mills. UNITED STATES STEEL CORPORATION. Feb. 11, 1959 [Feb. 6, 1958], No. 4824/59. Drawings to Specification. Class 38 (4). [Also in Group XXXVIII] In a multi-stand continuous hot-rolled metal strip mill a signal corresponding to the thickness of the strip at the first stand is compared with a reference signal developed by the same measuring device when the leading edge of the strip leaves the first stand, any error serving to adjust the setting of the rolls of the second stand to obtain constant strip thickness. As'described, the mill comprises six stands each of which has one D.C. motor driving the rolls and another for adjusting their spacing. The roll driving motors are associated with tachometer generators which, through a system involving a magnetic amplifier and amplidyne generator, maintain the speeds of the rolls at values determined by the settings of manual potentiometers and the magnitudes of control signals referred to below. The motors adjusting roll spacing are associated with selsyn generators which ensure that the spacings correspond with the settings of manual or programmed potentiometers and the magnitudes of further control signals referred to below. A voltage corresponding to the thickness of the material leaving the mill is produced by an X-ray gauge to control the speeds of the rolls of the last three stands. If this voltage exceeds predetermined limits the spacing of all or some of the rolls is also controlled. A motor-driven potentiometer is operated automatically so that the voltage from it balances that from a transducer responsive to the temperature of the bar entering the mill. After a predetermined time, when the trailing edge of the bar leaves the first stand this circuit is re-arranged so that a voltage corresponding to the difference in temperature of the next bar serves to modify the roll spacing of the first stand. The roll spacings of the other stands are also modified in a similar manner as the trailing edge passes them. A further motordriven potentiometer is operated automatically so that the voltage from it balances that from a transducer responsive to the force between the rolls of the first stand as the bar enters. After a predetermined time this circuit is rearranged so that a voltage corresponding to changes in the thickness of the bar serves to modify the roll spacing of the second stand and the speeds of the rolls of the first two stands. A still further motor-driven potentiometer is operated automatically so that the voltage from it balances that from a transducer responsive to the force between the rolls of the fourth or fifth stand when the bar enters. When the bar passes the sixth stand this circuit is rearranged so that a voltage corresponding to change in the bar thickness serves to modify the speeds of the rolls of the last three stands. A modification in which the speeds of the rolls of the first three stands are also modified in accordance with the change in force between the rolls of the first stand is referred to.
