Title: Improvements in control systems
IPC: G05B11/01
Filed: 1937-12-08
Abstract: 513,625. Resistance measurements. THORNTON, A. A. (Taylor Instrument Cos.). Dec. 8, 1937, No. 33974. [Class 37] Also in Group XXXVIII] In a system wherein a controlled member e.g. a recording pen is driven by a motor until the balance of a potentiometer network is restored, a secondary network is provided to prevent hunting of the system about the balance point. The non-hunting action may be augmented by an additional e.m.f. produced by a generator driven by the balancing motor. Fig. 1 shows a system for recording temperatures measured by a pyrometer 5. Normally the pyrometer e.m.f. is balanced by the voltage drop in a potentiometer 35, the circuit including a galvanometer relay 6 and a resistance 36 which forms the arm of a secondary network comprising resistances 37, 38, 47, 48, 50 and including a generator 15 driven by the motor 9 which controls the recording pen 11 and the adjustable contact 14 of the potentiometer 34. The motor 9 and its field windings 29, 30 are controlled by a pair of discharge tubes 7, 8 supplied from the transformer 23 and subjected to grid-control by the relay 6. Upon variation of temperature, the electrical balance is. upset and the relay 6 is operated in one or other direction to render the corresponding tube 7 or 8 conductive and effect control of the motor in the direction to restore balance. A portion of the motor current flows through the secondary network and due to its polarity decreases or even reverses the current flowing in the circuit of the relay 6 in order to produce an anticipatory control of the point of balance in such a way that the relay 6 tends to restore to cut off the motor before the contact 14 reaches the balance point. The generator 15 also produces current in the secondary network the effect of which is to augment this control. The contact 14 continues to move under the inertia effect of the motor 9 when the relay 6 is restored, the generator then causing the reverse operation of the relay 6 to produce a braking action on the motor. These operations are continued and may be repeated until the point of balance is reached. For very small movements the anticipatory action is effected almost entirely by the secondary network of resistances.
