Latest Patents

Eriksson's latest patents include a "Device in Core Barrels" and a "Releasing Device in Core Barrel Grapplers." The first patent addresses the need for an indicator in core drilling, which signals when a core barrel can no longer receive additional core material. This device features a valve that constricts the passage for flushing medium, resulting in a noticeable pressure increase. This mechanism not only alerts the operator but also allows a small amount of flushing medium to reach the drill bit, preventing overheating and potential damage. The second patent focuses on a device that facilitates the disengagement of a grappling device from a core barrel. This device is actuated by a recess in the drill rod bore, allowing for a smooth transition when the barrel reaches its working position.
