A circuit and a method for decoding data coded by blocks by a turbo-code including successive steps. The feeding apparatus is located in the upper portion of the container, and it serves to introduce inorganic material polluted with organic material into the container. During such operation the drive force exerted upon the punch is transmitted to the clamp by force transmitting means comprising an air pressure chamber of variable volume. For example, anchor trees may be located as being sets of sibling sub-trees with similar tag paths that contain the domain constraints. The hinges are fixed on the main body or the support stand.
