Title (EN) STATUS INDICATORS FOR USE IN EARTH-BORING TOOLS HAVING EXPANDABLE MEMBERS AND METHODS OF MAKING AND USING SUCH STATUS INDICATORS AND EARTH-BORING TOOLS
(FR) INDICATEURS DE STATUT UTILISÉS DANS DES OUTILS DE FORAGE DU SOL COMPORTANT DES ÉLÉMENTS EXTENSIBLES ET PROCÉDÉS DE FABRICATION ET D'UTILISATION DE TELS INDICATEURS DE STATUT ET D'OUTILS DE FORAGE DU SOL
Abstract: front page image
(EN)A status indicator for determining a position of an extendable member in an expandable apparatus. The status indicator is configured to decrease a cross-sectional area of a portion of a fluid path extending through an expandable causing a pressure of a fluid within the fluid path to increase when an extendable member of the expandable apparatus is in an extended position. By determining the pressure of the fluid within the fluid path, one can determine the position of the status indicator within the fluid path and thereby determine whether the extendable member of the expandable apparatus is in the extended or a retracted position.
(FR)L'invention concerne un indicateur de statut permettant de déterminer la position d'un élément extensible dans un appareil extensible. L'indicateur de statut est conçu pour réduire la surface de coupe transversale d'une partie d'un trajet de fluide s'étendant à travers un élément extensible, faisant que la pression du fluide dans le trajet de fluide augmente lorsqu'un élément extensible de l'appareil extensible est en position déployée. En déterminant la pression du fluide dans le trajet de fluide, il est possible de déterminer la position de l'indicateur de statut dans le trajet de fluide, et de déterminer ainsi si l'élément extensible de l'appareil extensible est en position déployée ou rétractée.
