    摘要： A system includes a particulate material sample that contains a fluid medium and a plurality of particles dispersed in the fluid medium. The system further includes a particle analysis apparatus having a sample cell and sample delivery means for delivering the particulate material sample to the sample cell, wherein the particle analysis apparatus is adapted to obtain particle information on at least one particle in that particulate material sample while the at least one particle is in the sample cell. Furthermore, the system also includes fluid manipulation means for manipulating movement of the fluid medium while the particle analysis apparatus is obtaining the particle information on the at least one particle, and a data processing apparatus that is adapted to determine a specific gravity of the at least one particle based on the obtained particle information.

    摘要： A screen panel assembly includes a screen panel and one or more raised screen components, wherein at least one of the raised screen components is disposed on the screen panel. Furthermore, each of the one or more raised screen components includes at least one inclined screen surface that defines a first plane that is oriented at a first angle relative to said screen panel. Additionally, the first plane is substantially aligned with a second plane that is oriented at a second angle relative to a third plane that is perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device.

    摘要： A system (100) for measuring drilling fluid properties includes a capillary rheometer (134) that is adapted to measure viscosity parameters of drilling fluid. The capillary rheometer (134) includes a feed chamber (135), the feed chamber (135) having a cavity (135a, 135b), at least a first drain port (144) for draining fluid out of the cavity (135a, 135b), a double wall (136) defining an annulus (140) that opens to the cavity (135a, 135b), and a feed port (142) in an outer portion (136a) of the double wall (136) that is in fluid communication with the annulus (140). The capillary rheometer (134) also includes at least a first capillary tube (146) coupled to at least the first drain port (144). Additionally, the disclosed system (100) further includes a pump (102) that is adapted to pump fluid to the feed port (142).

    摘要： An apparatus includes a body having a central axis, a fluid inlet coupled to the body, the fluid inlet being adapted to receive a flow of a fluid, and a fluid outlet coupled to the body. The fluid inlet and the fluid outlet are substantially coaxially aligned so as to define a flow axis through the apparatus, and the flow axis is laterally offset from and perpendicular to the central axis of the body. A rotating blade assembly is disposed within said body and includes a plurality of blades, wherein the rotating blade assembly is adapted to be controllably rotated about the central axis so as to control a fluid level of the flow of fluid entering the fluid inlet.
