Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
151 words
A NEW AND IMPROVED TIME RATIO CONTROL POWER CIRCUIT INCLUDING IN COMBINATION AT LEAST ONE LOAD CURRENT CARRYING CONDUCTIVITY CONTROLLED CONDUCTING DEVICE AND THE PRIMARY WINDING PORTION OF AN AUTOTRANSFORMER OPERATIVELY CONNECT IN SERIES CIRCUIT RELATIONSHIP ACROSS A PAIR OF POWER SUPPLY TERMINALS THAT IN TURN ARE ADAPTED TO BE CONNECTED ACROSS A SOURCE OF ELECTRIC POTENTIAL, MEANS FOR TURNING ON SAID CONDUCTIVITY CONTROLLED CONDUCTING DEVICE TO CAUSE IT TO CONDUCT, MEANS FOR TURNING OFF THE CONDUCTIVITY CONTROLLED CONDUCTING DEVICE AFTER A DESIRED INTERVAL OF CONDUCTION, A SECONDARY WINDING PORTION OF SAID AUTOTRANSFORMER INDUCTIVELY COUPLED TO SAID PRIMARY WINDING PORTION, A LOAD, FIRST LOAD CURRENT RECTIFYING MEANS OPERATIVELY COUPLING SAID LOAD TO SAID PRIMARY WINDING PORTION DURING INTERVALS OF CONDUCTION OF SAID CONDUCTIVITY CONTROLLED CONDUCTING DEVICE, AND SECOND LOAD CURRENT RECTIFYING MEANS OPERATIVELY COUPLING SAID LOAD TO SAID SECONDARY WINDING PORTION DURING INTERVALS OF NONCONDUCTION OF SAID CONDUCTIVITY CONTROLLED CONDUCTING DEVICE.
