摘要： A rotation actuated core orientation system (10) for a ground drill comprises an orientator (14) and rotation sensitive actuator (16). The actuator (16) is a dispersed system comprising two major components or subsystems namely a centrifugal mechanism (16a) and a time delay mechanism 16b between which is located the bottom orientator (14). The orientator (14) has an active state where the orientator provides a substantially instantaneous indication of a position of a known bearing or reference location in or of the hole, and a locked state where the orientator maintains the indication. The rotation sensitive actuator (16) isoperatively associated with the orientator (14) to actuate the orientator (14) to enter the active state or the locked state dependant on rotational speed of the ground drill.

摘要： An overshot (10) comprises a latching mechanism (12) for latching a member such as a spear point (14); and, an actuator (16) which actuates the latching mechanism (12). The latching mechanism (12) has a number of different operational states. One of these is a neutral state in which latching mechanism (12) is able to latch or capture a spear point (14). In the neutral state, latching mechanism (12) is able to open in order to receive spear point (14) and then self- close to latch or retain the spear point (14). Latching mechanism (12) also has a locked state in which it is locked in a closed position by actuator (16) to prevent the release of a latched spear point (14). The third state is the release state where the overshot is locked in an open position by actuator (16) to release a previously latched spear point (14). The actuator (16) operates as a linear to rotary motion converter which converts linear motion of one part of the actuator to a rotary motion of another part of the actuator between a plurality of rotationally spaced positions. The rotational positions determine the state of the latching mechanism.

摘要： A head assembly (10) comprises a spear head assembly (12) and a latching system (100) which are coupled together. The spearhead assembly (12) comprises a spear point (16) having a proximal end (18) pivotally coupled about a pivot axis (20) and a sleeve (22) that is biased in a direction toward a pointed end (24) of the spear point (16). The sleeve (22) is coupled with the spear point (16) so that the spear point (16) and the pivot axis (20) can move axially relative to the sleeve (22). The latching system (100) comprises a latch body (102) and two latch dogs (104a) and (104b) which are coupled to the latch body (102) and movable between latching position where the latch dog (16) from the latch body (102) and can engage a latching mechanism and a release position where the latch dogs (104) retract inwardly. The latching system (100) is configured to enable the latch dogs (104) to move parallel to each other rather than pivot when moving between the latch and release positions. The spear head assembly (12) enables the head assembly (10) to be coupled to an overshot to enable tripping through a drill string. The latching system (100) enables the head assembly (10) to selectively engage the latching mechanism inside the drill string to hold the head assembly (10) in at least one axial direction relative to the drill string.
