摘要： A system is disclosed for determining the distribution of the size of small particles contained in a sampled portion of a process stream containing particles at high concentrations. The system includes a light delivery arrangement that anamorphically modifies light energy received from a light source and projects the anamorphically modified light energy to an optical element contained in a sample cell. The optical element includes a passage that is arranged to receive therein particles of a predetermined size from the sampled portion of the process stream flowing in the sample cell. The anamorphically modified light energy is transmitted through the optical element and is focused within the passage to irradiate the particle ensemble therein. A light collection arrangement collects the light energy escaping from the optical element and focuses the light energy collected onto a detector array. The detector array develops output signals used to determine a measurement of the distribution of the size of the particles contained in the process stream.

摘要： A multiple pathlength sensor is disclosed that is installed substantially within a process stream containing particles at high concentrations. The sensor includes a transparent surface for receiving the first and the second light energy emissions projected by first and second light delivery arrangements. The first and second light energy emissions penetrate the transparent surface and enter the sensor in a first directional path. A first light deflecting surface modifies the first and second light energy emissions to travel into a second directional path through the sensor. A first passage exposed to the process stream is sized to receive particles of a first predetermined size range. The first light energy emission in the second directional path is projected through the first passage to irradiate the particle ensemble therein. A second passage exposed to the process stream is sized to receive particles of a second predetermined size range. The second light energy emission in the second directional path is projected through the second passage to irradiate the particle ensemble therein. A second light deflecting surface receives the light energy projected through the first and second passages and the light energy scattered by the particle ensemble in each of the first and said second passages. The second deflecting surface directionally modifies the light energy it receives to follow a third directional path through the sensor to the transparent surface, where the light energy escapes the sensor and is collected by a light collection arrangement.

摘要： An improved mixing reservoir is disclosed used for supplying particles suspended in a liquid, in the form of a slurry, for delivery and recirculation within a recirculating system. The mixing reservoir includes an outlet port at its lowest point connected to a recirculation pump. The pump is arranged to draw the slurry from the mixing chamber and to cause a stream of the slurry to flow through the recirculating system. The improved mixing reservoir includes a plurality of inlet ports located on the mixing reservoir. Each inlet port is connected to the recirculating system and the stream of slurry, whereby the particles contained in the slurry are retained in suspension by the resulting chaotic motion of the colliding streams of slurry as they are returned to the mixing reservoir.
