20190234852 | PARTICLE CHARACTERISATION INSTRUMENT - A particle characterisation instrument, comprising a light source, a sample cell, an optical element between the light source and sample cell and a detector. The optical element is configured to modify light from the light source to create a modified beam, the modified beam: a) interfering with itself to create an effective beam in the sample cell along an illumination axis and b) diverging in the far field to produce a dark region along the illumination axis that is substantially not illuminated at a distance from the sample cell. The detector is at the distance from the sample cell, and is configured to detect light scattered from the effective beam by a sample in the sample cell, the detector positioned to detect forward or back scattered light along a scattering axis that is at an angle of 0° to 10° from the illumination axis. | 2019-08-01 |
20190234853 | HOLOGRAPHIC CHARACTERIZATION USING HU MOMENTS - Holographic microscopy analysis system and methods for determining morphology of a particle in a sample. A bright-field reconstruction image is generated from a recorded hologram from a holographic microscopy system. Morphology of particles imaged by the system may be determined. Hu moments are calculated, either from the hologram or from the bright-field reconstruction, or both, to provide an indication of morphology. | 2019-08-01 |
20190234854 | CLASSIFICATION PARTICLE SIZE DISTRIBUTION MODIFICATION TECHNIQUE BASED ON HYDROPHOBIC MEDIA FOR ENHANCED FLUIDIZED BED FLOTATION SEPARATION - Apparatus is provided for mineral separation, featuring a mixer configured to mix a mineral bearing ore feed and hydrophobic media particles, the mineral bearing ore feed being crushed and ground and having an ore particle size distribution characterized by about 50% or more of particles at a size of about 150 μm or less with finer particulates and mid-range particles, the hydrophobic polymer based particles having a media size of about 300 μm or more and being configured to collect the finer particulates and mid-range particles in the mineral bearing ore through hydrophobic attraction, and provide a modified feed having loaded “coarse particles” loaded with the finer particulates and mid-range particles attached thereto for further processing. | 2019-08-01 |
20190234855 | MEASUREMENT APPARATUS, ENVIRONMENT MEASUREMENT APPARATUS AND MEASUREMENT METHOD - A measurement apparatus includes: a measurement tank including an air inlet and an air outlet; a fan; a light source configured to irradiate micro-particulate matter with light; a photodetector configured to detect scattered light from the micro-particulate matter; a first circuit configured to detect individual particles of the micro-particulate matter based on an output of the photodetector; a second circuit configured to detect a micro-particle group of the micro-particulate matter based on the output of the photodetector; a switch configured to switch into one of a first state in which the output of the photodetector is input to the first circuit and a second state in which the output of the photodetector is input to the second circuit; and a controller configured to control a drive and stop of the fan, a turn-on and a turn-off of the light source, and a switching of a state of the switch. | 2019-08-01 |
20190234856 | MULTI-FUNCTIONAL MULTI-FIELD COUPLING SEEPAGE EXPERIMENT DEVICE AND TESTING METHOD THEREOF - A multi-functional multi-field coupling seepage experiment device includes a device body, a stress field control system, a temperature field control system, a fluid loading control system and a fluid seepage measurement system. The present invention further discloses seepage experiments performed on tight gas, shale gas, tight oil, shale oil, natural gas hydrate and geothermal heat in a multi-field coupling state of a temperature field, a stress field, a pore pressure field and a seepage field. | 2019-08-01 |
