Abstract: In some examples, an apparatus for coupling and decoupling a connector head to and from an end of a wired drill pipe held by an elevator includes an actuator configured to move the connector head between a coupled position and a decoupled position. The actuator is configured to move the connector head in parallel with the longitudinal axis of the wired drill pipe before moving it away from said wired drill pipe when decoupling the connector head from the wired drill pipe, and to move the connector head into the longitudinal axis of the wired drill pipe before moving it in parallel with said longitudinal axis when coupling the connector head to the wired drill pipe.

Abstract: A drill bit with fixed cutter elements with a hollow upper conical pin connector connectable to the lower module of a drill string, where the upper conical pin connector has a transition to an upper cylindrical module with a central channel for supplying bore fluid from the drill string, equipped with, a lower bore holding a cylindrical socket from the lower module, connecting the upper and lower modules of the drill bit, where the central channel continues down through the lower module and branches out into nozzle channels with nozzles ending in the recesses in between the wings with fixed PDC-cutters, wherein elastic shock-absorber elements are arranged in recesses in the cylindrical wall of the bore, in the upper cylindrical module, and the elastic shock-absorbers are assembled on the bolts extending into the cylindrical socket of the lower module.
