Abstract

1,166,438. Repertory number sender. INTERNATIONAL STANDARD ELECTRIC CORP. 1 Feb., 1968 [7 Feb., 1967], No. 5126/68. Heading H4K. Each key of a keyset produces a multi-digit number as two one-out-of-four frequency code combinations for each digit. Actuation of a key connects clock pulses to a binary counter the outputs of which are converted into a sequential marking of fourteen digit leads corresponding to the maximum of fourteen possible digits. Each digit lead, according to the key operated, is selectively strapped to one out of each of two sets of four wires to operate one from each of two sets of four ferreed relays which control the sending of respective combinations of one high and one low audio tone.
