| A latching system has a latch body, a latch carrier and two latch dogs. The latch dogs are retained in the latch carrier by two pins. The latch carrier is located within the latch body. The latch body has slots through which the latch dogs can extend. The pins pass through both latch dogs and through longitudinal slots in the latch carrier. The pins are fixed at their opposite ends to the latch body. When the latch carrier is moved axially the latch dogs move parallel to each other between: a latching position where the latch dogs extend from the latch body and latch carrier and can engage a latching mechanism; and a release position where the latch dogs retract inwardly. | ||||||

| Implementations of the present invention include a core barrel assembly including external fluid pathways extending generally axially long the outer surface of the core barrel assembly. The one or more external fluid pathways can allow for increased fluid flow around a latch mechanism. The increased fluid flow around the latch mechanism can allow the core barrel assembly to travel faster within the drill string, can allow drilling fluid to pass by the latch mechanism when engaged. Implementations of the present invention also include drilling systems including external fluid pathways, and methods of retrieving a core sample using such drilling systems. | ||||||

| 95 | CORE DRILLING TOOLS WITH RETRACTABLY LOCKABLE DRIVEN LATCH MECHANISMS | US12968127 | 2010-12-14 | US20110079436A1 | 2011-04-07 | Christopher L. Drenth; George Iondov; George Ibrahim |
| Implementations of the present invention include a core barrel assembly having a driven latch mechanism. The driven latch mechanism can lock the core barrel assembly axially and rotationally relative to a drill string. The driven latch mechanism can include a plurality of wedge members positioned on a plurality of driving surfaces. Rotation of the drill string can cause the plurality of wedge members to wedge between an inner diameter of the drill string and the plurality of driving surfaces, thereby rotationally locking the core barrel assembly relative to the drill string. The driven latch mechanism can further include a refracted groove adapted to lock the plurality of wedge members radially within the core barrel assembly, thereby allowing for faster travel within the drill string. Implementations of the present invention also include drilling systems including such driven latch mechanisms, and methods of retrieving a core sample using such drilling systems. | ||||||

| A method in core drilling, wherein a tubular drill bit (8) being arranged at the end of a tubular drill string (6) is driven under rotation against a material intended for drilling, and wherein for the purpose of core retrieving, a tool (17, 20) is brought inside the drill string to an operative position in the area of the drill bit. Acoustic vibrations (24, 25) from the drill string are sensed when the tool is brought to its operative position, sensed acoustic vibrations are analysed for detecting the occurrence of acoustic vibrations characteristic for when the tool has reached its operative position, and an output signal is emitted when the occurrence of vibrations characteristic of when the tool has reached its operative position has been detected. The invention also concerns a device and a drill rig. | ||||||

| Inner core barrel head assembly (10) includes an upper latch body (24), a plurality of latching balls (26) which are retained in the latch body (24) and a locking sleeve (28) disposed within the latch body (24). The sleeve (28) has an outer circumferential latching surface (30) of a first outer diameter and an outer circumferential release surface (32) of a second outer diameter smaller than the first outer diameter. The locking sleeve is axially moveable relative to the upper latch body (24) between a latching position and a release position. In the latching position, the latching surface (30) is in radial alignment with the balls (26), forcing the balls (26) radially outwardly into a latch seat (12) provided on a core barrel (20) attached to a lower end of a drill rod (14). This latches the assembly (10) to the core barrel preventing withdrawal. In the release position, release surface (32) is in radial alignment with the balls (26) allowing the balls (26) to move radially inwardly out of engagement with the latch seat (12). | ||||||
