Abstract

Una disposición para producir oscilaciones ultrasonoras, en especial oscilaciones de gran potencia, que comprende un oscilador provisto de realimentación o retroacción y en el que la corriente de frecuencia ultrasónica producida por el oscilador es suministrada a un circuito de carga que incluye un transductor del cual se deriva una tensión eléctrica que es devuelta como tensión de realimentación por medio de un circuito de realimentación conectado al circuito de carga del oscilador, caracterizada dicha disposición por el hecho de que, para producir la tensión de realimentación, el transductor está conectado en una rama de un circuito de puente en tanto que en una segunda rama del puente hay conectada una impedancia que incluye una reactancia y las demás ramas del puente están constituidas por elementos independientes de la frecuencia.
