Apparatus for delivering predetermined weights of a material
First Claim
1. APPARATUF FOR DELIVERING A PREDETERMINTED WEIGHT OF MATERIAL, COMPRISING A HOPPER IN WHICH THE MATERIAL IS STORED, A CONTAINER TO WHICH THE MATERIAL IS TO BE DELIVERED, A CONTROL DEVICE FOR CONTROLLING DELIVERY FROM THE HOPPER TO THE CONTAINER, AN A.C. SOURCE, A BRIDE NETWORK CONNECTED TO SAID A.C. SOURCE, STRAIN GAUGES ASSOCIATED WITH SAID BRIDGE, MEANS CONNECTING SAID STRAIN GAUGES WITH SAID CONTAINER SO THAT THE OUTPUT FROM SAID BRIDGE HAS A MAGNITUDE DEPENDENT ON THE WEIGHT OF MATERIAL IN SAID CONTAINER, A TRANSFORMER HAVING A PRIMARY WINDING CONNECTED TO SAID A.C. SOURCE, AND A PLURALITY OF UNEQUAL SECONDARY WINDINGS, A PLURALITY OF ARMS MOVABLE OVER SAID SECONDARY WINDINGS RESPECTIVELY, AND INTERCONNECTED WHEREBY PREDETERMINED PROPORTIONS OF SAID WINDINGS CAN BE COMBINED TO PROVIDE THE SECONDARY OUTPUT OF SAID TRANSFORMER, AND MEANS FOR COMPARING THE SECONDARY OUTPUT FROM SAID TRANSFORMER WITH THE OUTPUT VOLTAGE FROM SAID BRIDGE, AND OPERATING SAID CONTROL DEVICE TO DELIVER MATERIAL UNTIL SAID SIGNALS ARE EQUAL.
