Some storage circuits based on valves

An explanation is given first of the use of a quantizing circuit with positive feedback to exhibit a multiplicity of stable states, and then of an alternative quantizer based on digital representation. Another principle for storage is described, providing storage in an inconvenient binary-digital system of numeration. A way of removing this defect is next given, to provide a cheap binary storage circuit. Finally, a generalization of these principles is proposed, to permit economical storage of several digits of radix other than two.
