Abstract
Abstract A control system for disposing each of a plurality of utilization circuits in a state responsive to the state of corresponding utilization controls. A plurality of series connected coders detect the state of the utilization controls associated therewith. Decoders associated with each of said coders and in series connection in the same sequence as said corresponding coders control the state of the corresponding utilization circuits. A column timer is in series connection with said coders and decoders for applying control signals thereto. Each of said coders and decoders are sequentially activated to a first active state during which they are operative to perform their assigned functions. Thereafter, each activated coder and decoder assumes an inactive state in which they permit the passage of control signals and data therethrough. Said control signals can be applied in either direction along said series connections.
