Abstract: Disclosed is a method/apparatus to determine any one of a plurality of parameters: shape, area, chemical composition, diameter, colour, number, thickness, width, length, absorptivity, reflectivity, transmittivity, dielectric constant, raman scattering profile, fluorescence, surface tension, roughness, profile, density, position and orientation. Also use of a plurality of energy beams as source energy: charged and neutral particle beams, gamma-, X-, micro-, optical and acoustic waves. The described apparatus determines the mean and standard deviation of a plurality of diameters of wool fibres, and includes a He-Ne laser (101), and a pinhole (102) which produce an expanding laser beam which passes through cell (105). Beam splitter (103) is operatively disposed to pinhole (102) and laser (101) to direct a portion of the laser beam to reference detector (109) which is electrically connected to processor (110) via line (111). When apparatus (100) is operating wool fibres in an isopropanol-wool slurry pass through cell (105) generally at a non-zero degree angle to the direction of slurry flow through cell (105) to interact with the laser beam in cell (105). Beam splitter (104) and microscope objective (106) are operatively disposed with respect to laser (101), pinhole (102) and cell (105)to produce an in focus magnified transmission image of wool fibres in cell (105) in the plane of end (107) of optical fibre bundle (108). Each of the fibres in bundle (108) is connected to a photodiode detector (112). Processor/timer (113) is connected electrically to detector (112) by line (114). Processor/timer (113) is also connected electrically to computer (115) by line (116) and to processor (110) by line (117). Detector (118) is connected electrically to processor (110) by line (119). Processor (110) is connected electrically to computer (115) by line (120). Detector (118) is operatively disposed with respect to laser (101), pinhole (102) and cell (105) to detect outgoing light.

Abstract: In order to make better use of cloth filters with which particles are filtered out of a gas, the particles are electrostatically charged upstream of the filters. The filtering is assisted by keeping the relative humidity of the gas at at least 5%. If corona phenomena appear, caused by the deposition of the dust particles in the electrostatic charging device, the outer electrode of the charging device is cooled. In this manner the moisture content is increased in the dust layer which has been deposited on the electrode.
