Abstract

1304944 Electric analogue calculating ASSOCIATED ELECTRICAL INDUSTRIES Ltd 10 June 1971 [29 June 1970] 31456/70 Heading G4G [Also in Division H1] A specimen stage of a microscope (see Division H1) can be provided with electric analogue calculating circuitry to control the movements of the stage. The circuitry automatically provides translatory movement to maintain a point of interest on the object on the axis of the microscope when the stage is tilted and also converts a tilt relative to this axis into two angles about respective tilting axes of the stage. The circuitry consists of potentiometers mounted on the shafts of motors controlling the movements of the stage, the potentiometers having trigonometrical characteristics. The signals derived from these potentiometers are combined together with signals from further potentiometers which are set according to the degree of tilt desired, in accordance with relationships stated in the Specification, and fed back to the motors to form a self-balancing system.
