Abstract

Servo amplifier 10 has its input connected to ground potential via transfer arm 11 and normally closed point 12 of control relay 13. An analog voltage V to be integrated is fed through the normally open point 14 to the input of the amplifier upon transfer of arm 11. The amplified voltage actuates bi-directional servo-motor 15 which is coupled to provide rotational power to feedback generator 16 and the driving portions of three clutches 17, 18 and 19. These are under the individual control of solenoids 20, 21 and 22. The driven portion of 17 serves to position slidewire 23 of grounded, center-tap feedback potentiometer 24 connected across a D.C. source. Potentiometer 24 has a case 25 linked to the driven portion of 19 for positionable adjustment.

An analog voltage V to be integrated is fed through the normally open point 14 to the input of the amplifier upon transfer of arm 11. The amplified voltage actuates bi-directional servo-motor 15 which is coupled to provide rotational power to feedback generator 16 and the driving portions of three clutches 17, 18 and 19. These are under the individual control of solenoids 20, 21 and 22. The driven portion of 17 serves to position slidewire 23 of grounded, center-tap feedback potentiometer 24 connected across a D.C. source. Potentiometer 24 has a case 25 linked to the driven portion of 19 for positionable adjustment. Clutch 18, when actuated, transfers mechanical power to slidewire 26 of a grounded, center tap output potentiometer 27 connected across a D.C. source. Negative feedback to the input of the amplifier is provided from the generator via line 28 and slidewire 23 via line 29.

At the beginning of an operational cycle of period t, relay 13 and solenoids 20 and 21 are simultaneously energized. This action provides a closed path through point 14 for the voltage V to be applied to the amplifier. Rotation of motor 15 is in a direction dependent upon the polarity of V. With clutches 17 and 18 now in coupled condition, slidewires 23 and 26 are moved to a position which is proportional to the magnitude and to the p...
