Abstract
1,234,592. Animal scare. SABA A SCHWARZWALDER APPARATE - BAU - ANSTALT AUGUST SCHWER SOHNE G.m.b.H. 5 June, 1968 [6 June, 1967], No. 26832/68. Heading A1E. [Also in Division G5] Animal calls are imitated by an audio frequency multivibrator frequency modulated by integrated or differentiated square wave pulses. The integrated or partly integrated pulses may frequency modulate the multivibrator directly or they may 100% amplitude modulate an auxiliary multivibrator which in turn modulates the audio frequency multivibrator. A third multivibrator may also frequency modulate the audio frequency multivibrator to produce croaking sounds.
