Multivibrator using semi-conductor pairs

Claim 1

A MULTIVIBRATOR, INCLUDING: A PAIR OF SUPPLY POINTS; AN OUTPUT SIGNAL; A PAIR OF ACTIVE DEVICES ELECTRICALLY DISPOSED TO BE ALTERNATELY CONDUCTING TO ALTERNATELY CONNECT THE OUTPOINT TO EACH OF THE PAIR OF SUPPLY POINTS, EACH OF SAID ACTIVE DEVICES COMPRISING A PNP TRANSISTOR AND A NPN TRANSISTOR, ONE TRANSISTOR OF EACH ACTIVE DEVICE CONNECTING ONE SUPPLY POINT TO THE OUTPUT POINT; A BIASING RESISTOR CONNECTED TO EACH SAID ONE TRANSISTOR; MEANS CONNECTING EACH SAID BIASING RESISTOR TO THE SECOND TRANSISTOR OF THE ASSOCIATED ACTIVE DEVICE TO SUPPLY A FORWARD BIAS THERETO UPON THE CONDUCTIVITY OF THE ONE TRANSISTOR IN THE ASSOCITED ACTIVE DEVICE; MEANS CONNECTING EACH SECOND TRANSISTOR TO FORWARD BIAS THE ONE TRANSISTOR OF THEIR RESPECTIVE DEVICE UPON THE CONDUCTIVITY OF THE SECOND TRANSISTOR IN THE ASSOCIATED ACTIVE DEVICE; MEANS FOR OPPOSITELY BIASING THE FIRST TRANSISTORS OF SAID ACTIVE DEVICES SO THAT THE TRANSISTOR IN ONE OF THE DEVICES WILL ALTERNATE IN CONDUCTION WITH THE TRANSISTORS OF THE OTHER DEVICE; AND MEANS FOR REVERSING THE RELATIVE BIAS ON THE FIRST TRANSISTOR OF ONE OF THE DEVICES RELATIVE TO THE BIAS ON THE FIRST TRANSISTOR OF THE OTHER DEVICE TO CHANGE THE CONDUCTING CONDITION OF SAID DEVICES.
