摘要： A spray nozzle includes a first flow channel providing a flow path between a first inlet and a first outlet, and a second flow channel providing a flow path between a second inlet and a second outlet surrounding the first outlet. The first flow channel is delimited by an inner casing and the second flow channel is delimited by an outer casing. In order to achieve an optimized level of uniformity of moisturizing fluid spray, the first outlet includes a plurality of first outlet openings, wherein the first outlet openings are separated by first slats extending helically at least a part of the distance between the first inlet and the first outlet.

摘要： Measurement apparatus including an optical sensor, which performs repeatedly transmission measurements through moving sheet of paper or board at at least one wavelength band dominantly absorbed by water, at at least one wavelength band dominantly absorbed by cellulose. The apparatus also includes an X-ray sensor, which performs repeatedly transmission measurements through the moving sheet of paper or board with photons of electromagnetic radiation (1 keV to 10 keV). The apparatus comprises a data processing unit, which receives signals with information on intensities of the optical and X-ray radiations passed through the sheet from the optical sensor and the X-ray sensor, and determines, based on the information, all of the following of the moving sheet: the dry stuff content as a function of the cellulose mass per unit area of the sheet, water mass per unit area of the sheet and the ash mass per unit area of the sheet.

摘要： The invention relates to an apparatus (100) for collecting dust samples. The apparatus comprises a piston (102) and a cylinder (110) for holding the piston with a body having a hole (108) extending through the body. The cylinder (110) has a first end (112), which is open, the first end of the cylinder being slanted such that underside (130) of the cylinder extends farther than upper side (132). A mechanism (114) moves the piston between inward and outward positions. The apparatus gathers dust flowing past the piston into the hole of the piston when the piston is in the outward position and moves the gathered dust by moving the piston into the inward position. An input feed (116) is configured to spread fluid through the hole filled with dust to flush the dust to an output feed (118).

摘要： A measuring device for measuring thickness of a planar object, where the measuring device comprises a first optical sensor module and a second optical sensor module that located on opposites of the measured planar object with mutual distance the optical sensor modules having at least one light source, a reference shade with two dimensional pattern and an imaging sensor and computing equipment, where the one light source is set to an angle towards measured object and the reference shade is set between the light and the object so that a shadow forms on the surface of the object and the imaging sensor is set so it can detect the reference shade and the shadow while the computing equipment calculates the distance between the surface of the object and sensor module from the distance between the detected shade and shadow of both optical modules and calculate the thickness of the object.

摘要： A measuring method includes: illuminating a silicone-coated layer using a light source; and imaging light from the light source that is specularly reflected from the silicone-coated layer to form an image of a surface of the silicone-coated layer. The method further includes detecting pores and/or voids in a silicone coating of the silicone-coated layer from the image; determining a silicone coverage of the silicone-coated layer based on the detected pores and/or voids; and determining a release force of the silicone-coated layer based on the silicone coverage.

摘要： A solution for measuring a suspension which contains wood fibres. The consistency of the suspension is changed in a consistency range. Optical radiation is directed at the suspension and the intensity of optical radiation interacted with the suspension is measured at different consistencies in the consistency range. The maximum intensity of the optical radiation is determined within the consistency range. At least one of the following properties of the suspension are determined based on the determined maximum intensity: kappa number, brightness.

摘要： A bleaching apparatus comprises a measurement chamber has a first substance, the amount of the first substance in the measurement chamber being known. A dosing unit inputs a second substance to the measurement chamber for causing a chemical reaction between the first substance and the second substance, one of the first substance and the second substance being chlorine dioxide and another of the first substance and the second substance being filtered sample from pulp slurry of a pulp process. At least one sensor performs detection of a property known to depend on the chemical reaction between the first substance and the second substance as a function of time. A data processing unit determines chemical demand of chlorine dioxide for washing loss in a bleaching sub-process on the basis of at least one value in the detected property within a known period of time after the input of the second substance.
