Abstract: A method and a system to be used in the process of manufacturing plates, such as fibreboards, particleboards and the like boards, where the raw material in the form of biomass particles, such as wood fibres or wood particles of various size and shape are dried from its natural moisture content to a moisture content suitable to be applied with a thermosetting binder and be spread onto a movable forming belt to form a mat, and where said mat by means of a hot press is compressed into the desired thickness of the finished plate and the thermosetting binder is hardened. According to the invention, the drying process of the biomass particles is facilitated by the use of ultrasound to remove the sub-layer of air at the surface of the particles and thus to intensify the transport of heat energy into the particles and the transport of moisture from the particles.

Abstract: A method of detecting a property of an object comprising directing a detection laser beam to the object to produce a scattered laser beam modulated corresponding to a motion of said object; receiving the scattered laser beam with an optical interferometer to produce an interferometric transmission signal and an interferometric reflection signal; combining the transmission signal and the reflection signal to generate an output signal corresponding to the motion of the object. In one embodiment the method comprises scaling at least one of the reflection signal and the transmission signal relative to the corresponding other signal by a predetermined relative scale factor; and combining the scaled reflection and transmission signals with one another to obtain the output signal. In another embodiment, the combining comprises generating the output signal as a ratio of a signal derived from the transmission signal and a signal derived from the reflection signal.

Abstract: This invention relates to an apparatus for the detection of the hydrogen content of an object, wherein said apparatus comprises a neutron source that emits fast/energy-rich neutrons; a detector device for detecting thermal neutrons; a moderator that brakes and reflects neutrons upon collision; wherein said detector device comprises a light-emitting unit that emits light in case of a nuclear event/reaction with a thermal neutron; a light-registering unit that emits an electric pulse/an electric signal when a flash of light is detected; and wherein said moderator is a light-conductive unit arranged between said light-emitting unit and said light-registering unit. Moreover the invention relates to a corresponding method of detecting hydrogen.
Abstract: This invention relates to an apparatus for detecting hydrogeneous material on a ship's deck comprising a neutron source located below the surface of the ship's deck and emitting fast/energy-rich neutrons, and a detector device that is located below the surface of the ship's deck and detecting thermal neutrons. The invention further relates to a corresponding method of detecting hydrogeneous material on a ship's deck. Hereby an apparatus and a method are provided for detecting occurrences of water on a ship's deck, wherein these occurrences appear in particular when travelling in rough weather conditions. The apparatus being located below the ship's deck, it is consequently not exposed to wear due to rough weather conditions.
Abstract: System for measuring layer thicknesses of a multi-layer pipe by measuring with a detector array (2) the attenuation of an X-ray transmitted though the pipe. According to the invention the detector array (2) comprises an array of detector elements D1, D2, D3, D4 with a collimator for defining the field of radiation in front of each detector element. The collimator has a narrow diaphragm aperture setting the resolution when the position of the pipe walls is to be determined. The defined field of radiation has an extent sufficient to radiate the four detector elements D1, D2, D3, D4 in parallel. In a suitable signal processing of the output signals from the detector elements D1, D2, D3, D4, eg by using the method of least squares, the thicknesses of the different layers may be fairly accurately determined.
