Patent CA-3025832-A1 (CA)
Inventor: GUI XIAHUI
IPC: B03D1/02
Filed: 2017-06-16
Abstract: A flotation method for a coal comprises: supplying, by means of a pump (E), a solution containing nanobubbles (5) to a mineral slurry mixing tank (F), and simultaneously supplying coal (7) and a flotation reagent (8) to the mineral slurry mixing tank (F); and supplying, by means of a material feeding pump (G), a mineral slurry mixture (9) to a countercurrent static micro-bubble flotation column (H) to undergo floatation, thereby obtaining two resulting products, a fine coal (10) and a tailing (11). The method utilizes a property of nanobubbles that the same preferentially gather at a hydrophobic surface, increasing the difference in hydrophobicity between the fine coal and coal gangue. The gathering of the nanobubbles also significantly reduces a fine mud covering a coal particle surface, thereby greatly reducing contamination caused by the fine mud, and increasing a recycling rate of the fine coal.

Abstract: Three dimensional tumor volume is analyzed spatially by genomics and transcriptomics, or both. Thin sections are cut with a microtome using a tape transfer technique so that the thin tissue sections remain without any distortion or deformation, in sequence relative to their position in the original tissue, so that a three-dimensional coordinate system can be anchored to each tissue section. Small samples of tissue are extracted or punched from very precise locations in the supports using the coordinate system as a grid, with known x,y,z location, and subjected to genomic sequencing. Sequence data is analyzed using the three dimensional coordinate system, so that the original tissue is thereby analyzed as a three dimensional system volume. At the same time, altemate tissue sections (or the same sections from which samples have been extracted with sample punches) can be subjected to staining and imaging to do histochemical analysis.

Abstract: A sparge (20, 40, 60 and 80) for use in a high-pressure vessel (26) operated at elevated temperatures and having high energy agitators (16) for suspending mineral containing particles in a slurry (36). The sparge (20, 40, 60 and 80) injects reagent fluids into the slurry (36) to reduce reaction times and for controlling process parameters for extracting valuable minerals from the particles. The sparge (20, 40, 60 and 80) has a vapour lock (constituted by components 24, 29, 30, 32, 44, 46, 64, 65, 66) to inhibit the flow of particulate material and detritus material under low or no fluid flow situations which occur commonly in the operation of high pressure autoclaves (26). The sparge (20, 40, 60 and 80) has a fluid flow path that increases in cross sectional area in the direction of flow of reagent fluids so as to keep reagent fluids flowing at a velocity below a critical impingement velocity that can cause metal materials of the sparge (20, 40, 60 and 80) to either wear rapidly or even to combust and in the worst case lead to loss of containment and violent and rapid depressurisation of the high pressure vessel (26).

Title: Target tracking systems and methods for uuv
Inventor: Wang hong jian
IPC: G05D1/10
Filed: 2020-01-13
Abstract: As the marine environment becomes more complex, the good target tracking system and method is essential for unmanned underwater vehicle (UUV). Firstly, the UUV tracking system is proposed, which includes Control System, Sensor System, Propulsion System, Communication System, Payload System and Energy System. UUV control system involves autonomous control system and motion control system, including integrated application of intelligent architecture, autonomous navigation, task planning, motion control and other subsystems.  Autonomous control system is the core and key system for UUV to autonomously complete operational tasks. It is equivalent to human brain playing the function of intelligent planning and decision-making based on sensory information, especially for UUV, is a key composition as a kind of unmanned systems without human guidance. Furthermore, this invention proposes the target tracking system based on Long Short-Term memory (LSTM) neural network. The target tracking system is implemented in autonomous control system. Finally, the target tracking system is verified on an unmanned mobile robot. The target tracking system based on LSTM neural network belongs to the field of unmanned underwater navigation. The invention uses LSTM neural network to track the target of complex and non-linear target. It solves the problems of difficult tracking of maneuvering targets, difficulty in establishing target models, and low tracking accuracy. First, we will collect the latitude and longitude information and velocity information of the target and perform data processing. Then, we design the LSTM neural network structure for single target tracking. Finally, LSTM neural network parameters will be adjusted optimally to achieve target tracking. The invention effectively simplifies the non-linear filtering process and can effectively track complex non-linear targets. It does not require the establishment of a target model and the use of traditional filtering algorithms. The target's historical information will be used to estimate the target's movement status at the next moment. At the same time, the neural network uses the internal parameters adjusted by the back-propagation algorithm and the attenuation of the learning rate to reduce the amount of calculation. This target tracking system is designed for unmanned vehicles and UUVs.
