Abstract
Abstract The present invention relates to a control system that uses a minimal number of distribution lines for interconnecting signal producing circuitry and signal utilization devices. In this way a large plurality of utilization devices may be activated by a suitable number of controllers in the signal producing circuitry; and the actual number of distribution lines is appreciably smaller than either the number of controllers or the number of utilization devices. Various types of signal producing controllers are shown; and a plurality of utilization devices and their interconnections are discussed, the utilization devices being ''''tuned'''' to be activated only by suitably associated control signals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A control system comprising: A. means for producing a plurality of control-signals; B. means for utilizing said control-signals; C. means, comprising a set of distribution-wires, for distributing said control-signals from said control-signals producing-means to said control-signal utilizing means; D. said control-signal producing-means comprising a plurality of controllers; a. said controllers being adapted to cause selected distribution-wires of said set of distribution-wires to act as return-wires for selected said control-signals; b. said controllers being adapted to cause selected distribution-wires of said set of distribution-wires to act as control-wires for selected said control-signals; c. said controllers being adapted to control the polarity of said control-signals; wherein limitation ''''b'''' comprises first means, including first electrical-connections from respective controllers to selected distribution-wires, for determining the particular distribution-wire that is to act as the control-wire for transmitting the control-signal associated with that particular controller; wherein limitation ''''c'''' comprises second means, including second electrical-connections from respective controllers to selected distribution-wires, for determining the particular distribution-wire that is to act as the return-wire for the control-signal associated with that particular controller.
Claim 2
Dependent Claim
174 words
A control system comprising: A. means for producing a plurality of control-signals; B. means for utilizing said control-signals; C. means, comprising a set of distribution-wires, for distributing said control-signals from said control-signals producing-means to said control-signal utilizing means; D. said control-signal producing-means comprising a plurality of controllers; a. said controllers being adapted to cause selected distribution-wires of said set of distribution-wires to act as return-wires for selected said control-signals; b. said controllers being adapted to cause selected distribution-wires of said set of distribution-wires to act as control-wires for selected said control-signals; c. said controllers being adapted to control the polarity of said control-signals; wherein limitation ''''b'''' comprises first means, including first electrical-connections from respective controllers to selected distribution-wires, for determining the particular distribution-wire that is to act as the control-wire for transmitting the control-signal associated with that particular controller; wherein limitation ''''c'''' comprises second means, including second electrical-connections from respective controllers to selected distribution-wires, for determining the particular distribution-wire that is to act as the return-wire for the control-signal associated with that particular controller.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 including rectifier means, incorporated into one of said electrical-connections, for determining the polarity of the control-signal associated with that particular controller.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 including switch means, incorporated into one of said electrical-connections, for decoupling respective controllers from said distribution-wires.
Claim 5
Dependent Claim
17 words
The apparatus of claim 3 wherein said switch-means is adapted to be actuated by an electrical coil.
Claim 6
Dependent Claim
17 words
The apparatus of claim 3 wherein said switch-means is adapted to be actuated by a timing mechanism.
Claim 7
Dependent Claim
17 words
The apparatus of claim 3 wherein said switch-means is adapted to be actuated by a magnetic force.
Claim 8
Dependent Claim
22 words
The apparatus of claim 3 wherein said switch-means comprises a double-pole arrangement having one pole thereof incorporated into each of said electrical-connections.
