  • Patent number: 7934568
    Abstract: A rock core removal method and apparatus allows efficient, safe, and reliable removal of a rock core sample. An inner collet tube and an outer ground tube, within a drill tube, protect the core sample during drilling. At depth, the collet tube is raised with respect to the ground tube so that the conical wall of the ground tube pushes constricting fingers on the collet tube inward, gripping the core sample within. The collet tube and ground tube are then raised, rotated, or raised and rotated, applying the necessary force to break the core sample off of the substrate. After retracting the tubes, the collet tube is lowered with respect to the ground tube to release the core sample. An ejection rod then pushes the core sample out of the collet tube. The ground tube may also act as the actuating means for a quick-change drill-bit release feature.

  • Patent number: 7404455
    Abstract: An apparatus is used with an impact hammer penetration assemble such as standard penetration test (SPT) in geotechnical engineering. The impact hammer penetration assembly comprises a penetration sample, a series of rods coupled together and an impact hammer apparatus. The drop of the hammer from a constant height hits the coupled rods and sampler in series and forces the sampler deeper into the ground. The apparatus includes a tip depth transducer and sampler to output a first electrical signal that is a function of the sampler tip position. A shock force transducer communicates the axial shock force in the rod to output a second electrical signal that is a function of the rod shock force and hammer blows. A shock penetration transducer communicates the movement of the coupled rods and sampler to output a third electrical signal that is a function of the sampler penetration due to the hammer blows. A micro-process controller monitors and processes the first, second and third signals in real time.

  • Publication number: 20080142262
    Abstract: Core drill bits with long crown heights are described herein. The core drill bits have a series of slots or openings that are not located at the tip of the crown and are therefore enclosed in the body of the crown. The slots may be staggered and/or stepped throughout the crown. As the cutting portion of the drill bit erodes through normal use, the fluid/debris notches at the tip of the bit are eliminated. As the erosion progresses, the slots become exposed and then they function as fluid/debris ways. This configuration allows the crown height to be extended and lengthened without substantially reducing the structural integrity of the drill bit. And with an extended crown height, the drill bit can last longer and require less tripping in and out of the borehole to replace the drill bit.
