Abstract

1,027,071. Transistor pulse circuits. REGULATOR A.G. May 27, 1963 [May 30, 1962], No. 21010/63. Heading H3T. [Also in Division H2] In a circuit in which a transistor 1 periodically switches current into a load 3, a bi-stable circuit 6 is operable by the emitter/collector voltage of the transistor 1 during the periods when transistor 1 is conductive, so as to protect the transistor 1 against excess current. Transistor 1 is preferably turned on and off by a multivibrator 2 which also resets or inhibits the bi-stable circuit 6 during the periods when transistor 1 is non-conductive.
