Abstract: According to the present invention, there is provided a treatment process system for biomass material and methods for such system. The system comprises a first dewatering stage arranged to receive biomass material, to remove liquid from the biomass material, and to feed the biomass material forward in the process. Further, the system includes a water treatment stage arranged to collect the removed liquid and an addition stage located downstream said dewatering stage and operatively coupled to the first dewatering stage. The addition stage is arranged to receive the de-watered biomass material, wherein the addition stage includes inlets for adding acid containing solution into the addition stage. A reactor stage arranged to receive the biomass material treated in the addition stage and to perform a pre-hydrolysis process to the biomass material. A filtrate feeding arrangement is arranged to feed liquid from the filtrate tank to the reactor stage.

Abstract: A mounting bracket for connecting two objects to one another. The mounting bracket includes an elongate protruding tongue element configured to be inserted in a cylindrical recess in one of the objects. The tongue element has one recess contacting side. A cross section of the tongue element on the recess contacting side is a circle sector with a radius, the other side of the tongue element being adapted to engage with a locking device. The locking device includes a cylinder and a lever connected to the cylinder. The cylinder is configured to be arranged in the recess adjacent the tongue element. The cylinder is configured to act as a cam when the cylinder is turned about its axis in the recess using the lever such that the cylinder is turned from a mounting position to a locking position in which a part of the locking surface pushes the tongue element such that the recess contacting side of the tongue element is in a pressing fit against the side of the recess.
