Abstract

Mejoras introducidas en el objeto de la patente principal nº 453.294, concedida el 12 de Diciembre de 1.977, por: Perfeccionamientos en relés electromagnéticos de alta sensibilidad, del tipo que comprenden una paleta móvil que se aplica sobre dos piezas polares de un circuito magnético bajo la acción del campo de un imán permanente, caracterizadas porque la paleta se somete a la acción de dos resortes de tracción que actúan en el sentido del despegado de la paleta somete a la acción de dos resortes de tracción que actúan en el sentido del despegado de la paleta en oposición de la atracción magnética del imán, a saber un primer resorte no regulable y un segundo resorte regulable, siendo los dos resortes dos piezas independientes pero cuyas acciones actúan conjuntamente.
