Abstract: A method for increasing the production of fine particles is provided. The method uses at least two types of fluids to be processed, a raw material fluid containing at least one type of fine particle raw material and a fluid for treating the fine particle raw material. Fine particles are obtained by mixing the fluids to be processed in a thin film fluid formed between at least two processing surfaces which are disposed to be faced with each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other. The production of the fine particles is increased by introducing the raw material fluid from the centers of the processing surfaces.

The middle region comprises a plurality of transverse sipes opening into the grooves, and the sipes have depths at least equal to 75% of the depth of the grooves.

Abstract: A hydraulic torque impulse generator includes a drive cylinder with a hydraulic fluid chamber, an output shaft with an impulse receiving portion connected to a radially movable seal element and intermittently dividing the hydraulic fluid chamber into high and low pressure compartments, and cam profiles which can displace the seal element from an idling position to a high pressure pulse generating position. A by-pass passage communicates fluid between the high and low pressure compartments, and a valve element movable between closed and open positions controls the fluid flow. The valve element is closed during pressure build-up in the high pressure compartment and opens when a high pressure pulse is completed, and is part of a control spindle coupled to the drive cylinder. The control spindle rotates through an angular play by inherent kinetic energy at an abrupt stop of the drive cylinder at the generation of each high pressure pulse.

Abstract: The invention relates to a method, systems, computer program, and computer-readable medium for reducing artefacts (speckling) which may appear to be noise/errors in a representation of an electrical signal. An Eye Pattern representation of a digital bit stream signal can be used for determining a range of signal quality characteristics, and can be generated from measurements of the proportion of ones and zeroes detected when sampling the signal at both at a reference data sampling position within a bit period and at a range of offset sampling positions. However, the speckling noise which typically exists in such an Eye Pattern reduces the confidence that can be placed in values for different signal characteristics which may be determined from the Eye Pattern.

The reader is arranged to couple to the antennas in order to read and store data from the transponders. The switch is positioned between the antennas and the reader to provide a selective coupling between the reader and each of the antennas. The controller controls the switch as a function of wheel-passage sensor signals.
