Abstract

SE PROPONE UN TRANSDUCTOR ULTRASONICO (1) CON UNA CARCASA (5) Y UN OSCILADOR CERAMICO CILINDRICO DELGADO (2) CON ELECTRODOS DE METAL (7,8) SITUADOS A CADA LADO DEL MISMO, Y UNA CAPA ADAPTABLE DE PLASTICO (3), DISPUESTA ENTRE UN LATERAL DEL OSCILADOR (2) DE CARA AL MEDIO QUE HA DE SER IRRADIADO Y LA MEMBRANA (6) FORMADA POR EL FONDO DE LA CARCASA DEL TRANSDUCTOR ULTRASONICO (1). EL ESPACIO LIBRE SOBRANTE EN LA CARCASA (5) ESTA OCUPADO POR UNA CAPA DE PLASTICO AMORTIGUADORA (4) DISEÑADA PARA AMORTIGUAR AL OSCILADOR (2). LA NOVEDAD DEL INVENTO RESIDE EN EL HECHO DE QUE LA CAPA AMORTIGUADORA (4) ESTA HECHA DE UN ELASTOMERO DE SILICONA DE ALTA DENSIDAD, CON UNA ALTA PROPORCION DE OXIDO DE METAL, QUE PUEDE SER MEZCLADA MECANICAMENTE Y UNIDA IN SITU DURANTE LA FASE DE GELIFICACION.
