Abstract: A method for production of coke chamber-compatible coal briquettes. Horizontally feeding coal into a pressing mold formed from a plate having two parallel terminating walls, which are stationary with respect to the direction of movement of the plate, and a terminating stop wall disposed transversely to the direction of movement of the plate. The side of the pressing mold open to coal is closed by a stationary wall, and the plate is locked in the horizontal direction for the pressing operation. The coal is compacted by a tamping device, having a vertically acting force onto pressing mold to produce a coal briquette. After completion of the coal briquette, the plate is moved horizontally in the longitudinal direction so that the space in the pressing mold becoming free in the horizontal direction is used for producing the next coal briquette. A device for carrying out the method is also disclosed.

Abstract: A method of forming a three dimensional fiber structure is disclosed which comprises the steps of a) providing a starting material which comprises liquid carrier, fibers and binder; b) passing the starting material over a substrate so as to deposit fibers onto the substrate; c) forming a three dimensional fiber matrix; and d) curing the binder. The flow of material onto the substrate may be controlled such that the flow of a starting material over the substrate is chaotic and fibers are laid down in a three dimensional structure containing a high proportion of voids.
