Abstract

UN METODO DE CONTROL DE ATRACCION/LIBERACION DE MATERIAL MAGNETICO QUE UTILIZA UN DISPOSITIVO DE PIPETA (P) QUE ABSORBE O DESCARGA UN LIQUIDO EN UN CONTENEDOR (1). UN CUERPO MAGNETICO (M) O CUERPOS, ESTAN DISPUESTOS EN UNA LINEA DE SUCCION LIQUIDA DEL DISPOSITIVO DE PIPETA (P) Y CUALQUIER MATERIAL MAGNETICO (3) CONTENIDO EN EL LIQUIDO ABSORBIDO EN LA LINEA DE SUCCION LIQUIDA MEDIANTE LA FUERZA MAGNETICA ES DEPOSITADO SOBRE LA SUPERFICIE INTERNA DE LA LINEA. EL MATERIAL MAGNETICO (3) ES LIBERADO Y DESCARGADO JUNTO CON EL LIQUIDO DESDE LA LINEA DE SUCCION LIQUIDA A UN ESTADO DONDE EL EFECTO DE LA FUERZA MAGNETICA GENERADA POR EL CUERPO MAGNETICO (M) ES CORTADA.
