    Abstract: L'invention concerne la surveillance des volets. Elle se rapporte à une broche dynamométrique destinée à former un pivot de fixation d'un volet hypersustentateur, et qui possède un corps cylindrique (10) ayant une tête hexagonale (12) et un embout fileté (14). Les dimensions et autres caractéristiques du corps (10), de la tête (12) et de 1'embout (14) correspondent à celles des pivots normalement utilises pour la fixation de ces volets hypersustentateurs. Le corps (10) possède une gorge (16) qui peut avoir une faible profondeur, de quelques dixièmes de millimètre, et forme un simple dégagement qui empêche le contact entre une branche d'étrier ou un bras de volet et la broche au niveau de la gorge (16). Un élément sensible (18) est place au niveau de la gorge et est enfermé de manière très étanche. Application aux volets des aéronefs.

    Abstract: A method of conversion of a water-based mud to a gel-based LCM quickly to control lost circulation in a lost circulation zone in a wellbore during continuous drilling with a drilling mud, the drilling mud comprises a volcanic ash, water, a de-foamer, a pH buffer, and a polymer. The method comprises the steps of entering the lost circulation zone, determining a lost circulation volumetric flow rate, metering a first amount of a binder into the drilling mud to create a binder containing mud, pumping the binder containing drilling mud into the wellbore, and suspending metering of the first amount of the binder to the drilling mud after a pre-defined regulating period of time effective to permit the binder containing drilling mud to create a gel-based LCM operable to alter the lost circulation zone.
