Abstract
945,150. Timed control of variables. G. PAGGI. April 20, 1960 [ April 23, 1959], No. 13858/60. Drawings to Specification. Headings G3N and G3T. A graph of the desired value of a variable with respect to time is formed as a conducting line on an insulating disc, drum or chart driven by a clock-motor. A pair of contacts mounted on pointers movable in response to variations in the value of the controlled variable, and co-operating with the conducting graph are connected to two separate control circuits each applying a different correction to the controlled variable. In a modification Fig. 2, not shown, one of the contact carrying pointers may be fixed. As described the contacts vary the bias on the trigger electrode of an electronic tube d controlling a relay e having contacts f in the correcting circuit g.
