Abstract

UN COBERTOR (3) PARA UN CUERPO DE HORNO (2) ESTA CONECTADO A CADA UNO DE LOS DOS ELECTRODOS SUPERIORES (16,17) QUE SE EXTIENDEN A TRAVES DE LAS PORCIONES DEL COBERTOR DEL HORNO (3) QUE ESTAN SEPARADAS HORIZONTALMENTE UNA DE OTRA A UNA DISTANCIA PREDETERMINADA. LOS ELECTRODOS SUPERIORES (16,179 TIENEN CONDUCTORES SUPERIORES (20,21) QUE SE EXTIENDEN EN LAS DIRECCIONES EN LAS QUE LOS CONDUCTORES (20,219ESTAN LEJOS DE LOS OTROS ELECTRODOS SUPERIORES. DOS CONDUCTORES INFERIORES (22,23) ESTAN SITUADOS DE FORMA QUE ESTEN CONECTADOS A UN ELECTRODO INFERIOR (1) Y SE EXTIENDEN EN LA MISMA DIRECCION DE LOS CONDUCTORES SUPERIORES (20,219. CIRCUITOS SEPARADOS DE FUENTE DE ENERGIA (24,25) ESTAN COLOCADOS ENTRE LOS EXTREMOS EXTENDIDOS DE UN JUEGO DE CONDUCTORES SUPERIOR E INFERIOR (20,22) Y ENTRE AQUELLOS DEL OTRO JUEGO DE CONDUCTORES SUPERIOR E INFERIOR (21,23), Y LOS ARCOS (12A,12B) QUE OCURREN ENTRE LOS ELECTRODOS SUPERIORES E INFERIORES (16,1;17,1) ESTAN DIRIGIDOS HACIA EL CENTRO DEL CUERPO DEL HORNO(2).
