Abstract

CIRCULO OSCILANTE DE PROTECCION DE MERCANCIAS CONTRA EL ROBO.COMPRENDE UN ARROLLAMIENTO (7), FORMADO POR UN CONDUCTOR ELECTRICO AISLADO (11) Y UN CONDENSADOR (5) CONECTADO EN PARALELO CON EL MISMO, ESTANDO EL CONDENSADOR (5) FORMADO POR PARTES (11B, 11C) RETORCIDAS ENTRE SI DEL CONDUTOR AISLADO (11), LAS CUALES ESTAN UNIDAS EN LOS DOS EXTREMOS DEL ARROLLAMIENTO CON LA PARTE (11A) DEL CONDUCTOR (11) QUE LO FORMA. EL AISLAMIENTO DEL CONDUCTOR ES UN TERMOPLASTICO SOLDABLE, PARTICULARMENTE UNA POLIOLEFINA.
