Abstract
SE DESCRIBE UN SEPARADOR QUE CONTIENE UNA REJILLA DE INCONEL Y UNA BANDA CIRCUNDANTE DE ALEACION DE ZIRCONIO. LA REJILLA DE INCONEL SE PUEDE FABRICAR DE METAL DE RESORTE MUY ELASTICO Y EXTREMADAMENTE FINO. LA REJILLA COMPRENDE CELULAS CON PATAS DE RESORTE VERTICAL DOBLADAS HACIA DENTRO EMPAREJADAS (24), (26) CON PARES DE BRAZOS INFERIOR Y SUPERIOR DE VARILLA QUE LOS CIRCULAN Y SOBRESALIENTES (28), (30). LAS PATAS DE RESORTE (24), (26) SE EXTIENDEN EN LUGARES SEPARADOS ENTRE LOS PARES DE BRAZOS SUPERIOR E INFERIOR (28), (30) Y TIENEN UNA PARTE DE CONTACTO DE VARILLA DE RESORTE MEDIO (25), (27) PARA DESVIAR LAS VARILLAS EN PUNTOS (45), (46), (47), (48) EN LOS PARES DE BRAZOS CIRCUNDADOS POR VARILLAS (28), (30). LOS RESORTES EN LOS EXTREMOS SUPERIOR E INFERIOR ESTAN PROVISTOS CON TOPES DIMPLE (34), (35), (36), (37) PARA IMPEDIR LA SOBRETENSION DEL RESORTE DURANTE EL MONTAJE O MANEJO. LOS PARES DE BRAZOS CIRCUNDADOS POR VARILLAS (28), (30) TIENEN DIFERENTES LONGITUDES PARA DAR DESPUES DEL MONTAJE DE LAS PATAS CORTA Y LARGA DE BRAZOS DE CELULAS ADYACENTES UNA CONFIGURACION DE SOLAPADA. LOS ESTRECHAMIENTOS ENTRE LOS EXTREMOS DE LOS BRAZOS (50), (51) ESTAN COMPENSADOS. EL SOLDADO DE PUNTOS DE LOS DOS PARES DE BRAZOS FORMA UNA UNIDAD ESTRUCTURALMENTE RIGIDO. SE DESCRIBE UNA BANDA TODA DE ALEACION DE ZIRCONIO PARA RODEAR LAS CELULAS DE REJILLA DE INCONEL. UNAS ABERTURAS EN LA BANDA Y EN LAS ESQUINAS, PERMITE ENCLAVAR LA REJILLA A LA BANDA DE INCONEL.
