| description | A core drilling latch assembly for use in terrestrial core drilling operations. The latch assembly incorporates features and elements which affect the flow of drilling fluids past the latch assembly and toward the drill bit, depending upon whether the latch assembly has contacted the landing ring in the drill string and whether the latch assembly has locked in place within the string. Accordingly, the latch assembly signals the drilling crew by pressure fluctuations when the latch assembly is in proper position within the drill string, and whether it is locked in position. |
