Abstract: An elastic sieving method and corresponding large-sized elastic vibration screen The present invention utilizes a screening surface and a separate sieving machine. A screen mat located on the sieve box is connected to multiple small rectangular screens. While the machine is vibrating, the resonation of screen rods located on the screen mat connected by small rectangular screens are initiated to screen the material and to cause the vibration of the whole vibration screen and realize the conveyance and lamination of materials. Because the screening surface is in a state of resonance, the vibration strength is strong enough to prevent the screen meshes from becoming plugged, allowing for high sieving efficiency. A bearing in the sieving mechanism is installed with a vibration damping ring, placing the bearing in a resonant state, allowing for a low dynamic stress level, which satisfies the process requirement for large-sized vibration screen excitation units with a screening surface as wide as 4800 mm.

Abstract: Use of more exotic laying patterns in connection with establishing paving stones of concrete blocks for e.g. paving on yards, are not widely used for cost reasons, as the automated laying machines laying the said paving stones in large surfaces at a time require the stones to be delivered in palletised formats which are handled by machine. The only way in which the said stereotype formats can be laid by machine is, if the paving stones are supplied manually, patterned layers on pallets. There is thus indicated a method for automatic sorting of paving stones (2) of different size from bulk condition to e.g. patterned laid palletisable layers in a standard out format, as the stones (2) after being guided into a row (3) are registered by size by a vision based system and guided into arraying lanes (34) from where these may selectively be dispensed in the preferred laying patterns in the said out formats (22).

Abstract: An optical cracked-grain selector that does not mistakenly identify normal grains of rice having no cracks as cracked grains due to the presence of the embryonic portion and/or surface scratches when optically identifying cracked grains of rice mixed in with material rice grains. An identification part in a cracked grain identification unit obtains a first rice grain image (having an embryonic portion and scratches) based on light passed through the rice grain that is received by a first CCD sensor built into a CCD camera of a photoreaction detection unit and a second rice grain image (having cracks, an embryo portion and scratches) based on light passed through the rice grain received by a second CCD sensor built into the CCD camera, acquires an image of the cracks by calculating a difference in the amount of light between the two rice grain images, and identifies a cracked grain.

Abstract: The present invention provides a method of operating a flushable filter column for a liquid. During the operation of a filter column, comprising several filter units, for a liquid, the filter units are flown through by the liquid in a forward direction in a filtering flow in the sense of filtering and in a flushing flow in reverse in the sense of reverse flushing. For each group of filter units, that can be blocked and reverse flushed together, a control valve, actuatable by its own electromagnet, is provided. The control valves are triggered in such a manner by an electronic control device depending on a state or operational parameter, which represent the degree of soiling of the filter unit, that the groups can be opened to the filtering flow or switched for blocking and reverse flushing. The reverse flushing is carried out in a flushing cycle, i.e. all filter units of the filter column are reverse flushed after one another, in succession.

This total force and the fluid pressure are monitored using a load cell and a pressure sensor respectively. The compression force operating on the media bed is then computed based on these measurements and compared to the optimal value. The position of the adjustment assembly within the column is then modified in response to changes in the measured compression force.
