Abstract

A simple and efficient storage circuit can be provided using latch type relays. The alpha-numeric information to be stored sets up code relays A, B, 1, 2, 4, 8 (or to any other code system) in accordance with the character read.

Automatic Resetting Storage

A simple and efficient storage circuit can be provided using latch type relays. The alpha-numeric information to be stored sets up code relays A, B, 1, 2, 4, 8 (or to any other code system) in accordance with the character read.

The code relays have transfer contacts which, when operated, set up the associated latch relay by means of an input pulse passed through the operated transfer contact. All unoperated transfer contacts will cause the associated latch relay to trip when the input pulse is applied.

To control sequential storage setup, normal column shift techniques can be applied between the latch relay storage groups and the single set of code relays.

The advantages of such a system are:

1. Less power required, since the storage relays are

mechanically held latched up.

2. Better balance of power required, as the same number of

coils are energized with each input pulse.

3. No external reset control is necessary, which provides a

reduction of circuit components and increases overall speed

of operation.

4. No loss of information on a power failure.

5. Reduced generation of heat on long storage durations.
