Switching matrices with protection against short-circuit in the gates at the crossings

Claim 1

A SWITCHING MATRIX COMPRISING A PLURALITY OF INPUT CONDUCTORS AND A PLURALITY OF OUTPUT CONDUCTORS DEFINING A PLURALITY OF CONDUCTOR CROSSINGS BETWEEN SEPARATE INPUT AND OUTPUT CONDUCTORS, NORMALLY CLOSED CROSSIN GATE MEANS AT EACH OF SAID CROSSING, SAID CROSSING GATE BEING ARRANGED TO BE SELECTIVELY OPENED AT FIRST INSTANTS OF A PULSE CYCLE WHEREBY ANY INPUT CONDUCTOR IS CONNECTED TO NO MORE THAN ONE OUTPUT CONDUCTOR AT SAID FIRST INSTANTS, FIRST AND SECOND POINTS OF DIFFERENT POTENTIAL, MEANS CONNECTING SAID OUTPUT CONDUCTORS TO SAID SECOND POINT, FIRST AND SECOND STORING PULSE GENERATORS HAVING FIRST AND SECOND SETTING WINDINGS RESPECTIVELY, FIRST AND SECOND FIRING WINDINGS RESPECTIVELY, AND FIRST AND SECOND OUTPUT WINDINGS RESPECTIVELY, FIRST SECOND AND THIRD NORMALLY CLOSED GATE MEANS, MEANS CONNECTING SAID FIRST GATE MEANS BETWEEN SAID FIRST POINT AND ONE OF SAID INPUT CONDUCTORS, MEANS CONNECTING SAID SECOND GATE MEANS AND FIRST SETTING WINDING SERIALLY BETWEEN SAID FIRST POINT AND SAID ONE CONDUCTOR, MEANS CONNECTING SAID SECOND SETTING WINDING AND THIRD GATE MEANS SERIALLY BETWEEN SAID ONE CONDUCTOR AND SAID SECOND POINT, A SOURCE OF INFORMATION SIGNALS CONNECTED TO OPERATE SAID FIRST GATE MEANS, A SOURCE OF PLUSE SIGNALS CONNECTED TO SAID SECOND AND THIRD GATE MEANS TO OPEN SAID SECOND AND THIRD GATE MEANS SIMULTANEOUSLY AT A SECOND INSTANT AND SEPARATELY AT THIRD AND FOURTH INSTANTS OF SAID PULSE CYLCES, MEANS FOR CONNECTING SAID PULSE SOURCE TO SAID FIRST AND SECOND FIRING WINDINGS TO APPLY PULSE THERETO SUBSEQUENT THE APPLICATION OF PULSES TO THE RESPECTIVE SERIALLY CONNECTED GATE MEANS, AND OUTPUT CIRCUIT MEANS CONNECTED TO SAID FIRST AND SECOND OUTPUT WINDINGS.
