Abstract

Abstract An information transfer system for transferring binary information from a first storage unit to a second storage unit in successive steps utilizing an intermediate storage unit and gates differently responsive to various conditions of an energizing source. During one condition of the energizing source, the binary information is transferred from the first storage unit to the intermediate storage unit, gates allowing communication between the first storage unit and the intermediate storage unit while blocking communication between the intermediate storage unit and the second storage unit. During another condition of the energizing source, the binary information is transferred from the intermediate storage unit to the second storage unit, gates allowing communication between the intermediate storage unit and the second storage unit while blocking communication between the intermediate storage unit and the first storage unit. The gates are differently responsive to two predetermined conditions of the energizing source in order to effect the desired communication and transfer of information between the storage units while these gates are non responsive to the energizing source when it is changing between these predetermined conditions so that the desired operation of the system is achieved only during two predetermined conditions of the energizing source.
