Abstract

SE PROPONE APROVECHAR LA DISOLUCION ENDOTERMICA DE 3HE EN 4HE. UN DEPOSITO DE MEZCLA (6) COLOCADO EN UN RECIPIENTE A VACIO (1) ENFRIADO A LAS PROXIMIDADES DE 2 K O MENOS, RECUBIERTO PERMANENTEMENTE DE 3HE Y DE 4HE LIQUIDOS POR CONDUCTOS SEPARADOS (2), (3). SE EXTRAE LA DISOLUCION PRODUCIDA EN UN TERCER CONDUCTO (4), A UNA VELOCIDAD TAL, HABIDA CUENTA DEL DIAMETRO DEL CONDUCTO, QUE EL 3HE NO PUEDE DIFUNDIR A CONTRACORRIENTE EN LA DISOLUCION DE FORMA SUFICIENTE PARA ELEVAR DE MODO NOTABLE EL CONTENIDO EN 3HE DEL 4HE LIQUIDO INTRODUCIDO, Y REDUCIR LA DISOLUCION, EN ESTE 4HE, DEL LIQUIDO 3HE INTRODUCIDO SIMULTANEAMENTE.
