  • Patent number: 8984967
    Abstract: The present disclosure relates to a method for sampling rock mass, especially jointed rock mass. The present disclosure provides a simple and convenient method for sampling jointed rock mass to prevent the rock sample from being disturbed and damaged during sampling and accordingly resulting in opening of the weak structural planes, to therefore obtain rock specimen correctly reflecting the basic physical and mechanical characteristics of rock mass comprising integral fissure network. The method for sampling jointed rock mass of the present disclosure comprises the following steps: Step a: Siting; Step b: Drilling; Step c: Protecting; and Step d: Sampling. The method is suitable for determining the basic mechanical properties of the rock mass and for assessing the stability of caverns in jointed rock mass.

  • Patent number: 8978489
    Abstract: Provided is a combustion gas bleeding probe, which is elongated in lifetime and improved in chlorine removing ability and so on. The combustion gas bleeding probe (1) comprises a cold gas discharge means having a plurality of discharge ports (2b) for discharging cold gases (C) substantially perpendicularly of the suction direction (S) of a combustion gas (G) and toward the center of the combustion gas flow. A vector (A), which is composed of momentum vectors (MVs) of the cold gas (C) discharged individually from the plural discharge ports, has a vertically downward component. This vertically downward component of the synthesized vector is made the larger, as the angle between the suction direction of the combustion gas and the flow direction of the combustion gas before sucked by the probe becomes the closer to a right angle.

  • Publication number: 20150040689
    Abstract: In example embodiments, particle collection efficiency in aerosol analyzers and other particle measuring instruments is improved by a particle capture device that employs multiple collisions to decrease momentum of particles until the particles are collected (e.g., vaporized or come to rest). The particle collection device includes an aperture through which a focused particle beam enters. A collection enclosure is coupled to the aperture and has one or more internal surfaces against which particles of the focused beam collide. One or more features are employed in the collection enclosure to promote particles to collide multiple times within the enclosure, and thereby be vaporized or come to rest, rather than escape through the aperture.
