A mercury delay line storage unit

A description is given of a storage unit for an electronic digital computer. Mercury delay lines are used as the storage elements and their construction and operating, characteristics are discussed. Information is stored in binary form by keeping pulses circulating around a loop which includes a mercury delay line. The electronic circuits associated with this loop are also described. Finally a method is discussed of interspacing the pulses of one loop between those of another loop and so doubling the storage capacity.
