Abstract: A Logicore construction board, a method and a composition thereof involve use of lignite ash-slag, wood waste particles and a synthetic adhesive. Lignite ash-slag is a waste mineral product which is widely available, but presently has no use. The present invention solves an important ecological problem by converting the waste product into a useful product. Lignite ash-slag and a synthetic adhesive of urea-formaldehyde resin of P-type and a hardener of a predetermined resin to hardener ratio are first mixed. Separately, wood particles and the synthetic adhesive of a predetermined resin to hardener ratio are mixed. The two mixtures of the lignite ash-slag and the wood particles are then mixed together. The combined mixtures are then poured to form a blanket and then pressed at a room temperature followed by a heat press to form a board. The board is water-proof, fire-proof and corrosion-resistant.

Abstract: A control system is disclosed for controlling the filling of bottles, flacons, and the like with a predetermined weight, whereby the value of the weight measured during the filling operation at which the tap associated with every filling zone is turned off, can be corrected automatically. The system comprises device for processing the value of the weight difference between the theoretical value, of the real value of the weight of one bottle, as measured on completion of the filling operation, for every filling zone. Control devices are also provided for processing a correction factor on the basis of the calculated weight difference, to obtain a new value for the weight measured during the filling operation, at which value the tap associated with that channel must be turned off. Also disclosed is the method of weight responsive filling on which the system operates.
