ABSTRACT:
A number of values of a variable defining a program of operations are settable by means of three potentiometers, connected to a controlled apparatus, which control respectively the initial, final, and rate of change of the variable, each potentiometer having an associated plate one edge of which indicates the value set against a scale. The plate edges form a curve of a graph indicative of the program. In a modification a plurality of linear potentiometers are located at different positions along a scale showing stages in the program, the sliders of the potentiometers being used to set and also indicate the value of the variable at each stage.
