Abstract

LA FUERZA PROPULSORA DE UN MIEMBRO DE LINEA (25) TRANSMISION OPTICA MOVIENDOSE SOBRE UN PASAJE TUBULAR (11, LL'') PUEDE SER VARIADA DE MANERA QUE LA LINEA VIAJA HACIA O SE RETIENE A VELOCIDA OPTIMA SIN RIESGO DE DAÑAR LA LINEA O EL APARATO ASOCIADO. UNA CURVA ES PROVISTA EN UNA PROCION DEL PASJE DE MANERA QUE UNA LINEA DE TRANSMISION ESTE SUJETA, BUCLES DE FUERZA COMPRESIVAS INACEPTABLES RESPECTO AL LADO EXTERIOR DE LA CURVA. UN SENSOR (49, 51) DETECTA LA PRESENCIA O AUSENCIA DE LA INEA EN ESTE PUNTO Y UN CIRCUITO DE CONTROL 823) VARIA LA FUERZA PROPULSORA. TENSIONES EXCESIVAS EN LA FIBRA PUEDEN SER DETECTADAS TAMBIEN. UN SISTEMA MODIFICADO EMPLEA DEFLECTORES PARA ASEGURAR QUE EL BUCLAJE OCURRA POR TORCEDURA EN DIRECCION HACIA EL SENSOR CON LA LINEA DE TRANSMISION NO DEFLECTADA DA BAJO UNA TENSION CORRECTA. LA INVENCION ENCUENTRA UNA APLICACION PARTICULAR EN UN METODO DE TORCEDURA DE FIBRA DONDE UNA LINEA DE FIBRA DE TRANSMISION OPTICA ES PROPULSADA A LO LARGO DE UN TUBO MEDIANTE UN FLUIDO DE ARRASTRE.
