Abstract

1. A munition safing, arming and firing system comprising means for transmitting a code consisting of pulses of differing frequencies, means for receiving said code, means for segregating the received pulses according to frequency, a stepping relay having a plurality of contact decks each of which corresponds to one of the frequencies contained in said code and one additional contact deck, each of said contact decks having an associated wiper arm, said wiper arms being ganged for conjoint movement, means connected to said segregating means for applying ground potential to only one of the wiper arms of said plurality of contact decks, in response to a pulse of the corresponding frequency means interconnecting the contacts of said plurality of contact decks in correspondence with a preselected code, switch means for advancing said wiper arms one contact position in response to each pulse received by said receiving means, code check means connected to said interconnecting means for freerunning said stepping switch back to its initial position after a predetermined time delay in response to a pulse which deviates from said preselected code, time delay means connected to said code check means for free-running said stepping relay back to its initial position after a predetermined time independently of the receipt of an incorrect pulse, arming circuit means connected to a predetermined contact of said additional contact deck, firing circuit means connected to a contact succeeding said predetermined contact and to said code check means so that upon the receipt of a correct series of pulses followed by an incorrect pulse the firing circuit will be activated through said code check means.

Claims

1. A munition safing, arming and firing system comprising means for transmitting a code consisting of pulses of differing frequencies, means for receiving said code, means for segregating the received pulses according to frequency, a stepping relay having a plurality of contact decks each of which corresponds to one of the frequencies contained in said code and one additional contact deck, each of said contact decks having an associated wiper arm, said wiper arms being ganged for conjoint movement, means connected to said segregating means for applying ground potential to only one of the wiper arms of said plurality of contact decks in response to a pulse of the corresponding frequency, means interconnecting the contacts of said plurality of contact decks in correspondence with a preselected code, switch means for advancing said wiper arms one contact position in response to each pulse received by said receiving means, code check means connected to said interconnecting means for freerunning said stepping switch back to its initial position after a predetermined time delay in response to a pulse which deviates from said preselected code, time delay means connected to said code check means for free-running said stepping relay back to its initial position after a predetermined time independently of the receipt of an incorrect pulse, arming circuit means connected to a predetermined contact of said additional contact deck, firing circuit means connected to a contact succeeding said predetermined contact and to said code check means so that upon the receipt of a correct series of pulses followed by an incorrect pulse the firing circuit will be activated through said code check means.

2. The device of claim 1 in which there is additionally provided code reversing means for causing said code check means to respond to a correct rather than an incorrect pulse and switch means responsive to the deliberate stopping of said wiper arms at a predetermined contact for a preselected length of time for activating said code reversing means.
