Abstract: The invention relates to a tissue paper making machine designed for possible rebuild from one concept to another. The machine comprises a forming section (2) and a Yankee drying cylinder (3) mounted to be rotatable about a first axis of rotation (A1). The forming section has a forming roll mounted for rotation about a second axis of rotation (A2) which is parallel to the first axis of rotation (A1). The forming section (2) has a head box (5) and a first and a second forming fabric (6,7). The head box (5) is arranged to inject stock into a gap (8) between the first forming fabric (6) and the second forming fabric (7). The first forming fabric (6) is a felt that forms a loop and is arranged to carry a newly formed fibrous web (W) from the forming section (2) to the Yankee drying cylinder (3). The tissue paper making machine (1) comprises a press roll (9) arranged inside the loop of the first forming fabric (6) and forming a nip (N) against the Yankee drying cylinder (3).

Abstract: A method of ensuring the flatness of a vane that is mounted in a headbox by means of a mounting arrangement including engagement dowels for cooperation with a downstream support wall of a transverse groove, said vane being affected during operation by shearing forces from the stock and by retaining forces from the mounting arrangement. In accordance with the invention outer engagement dowels are mounted at the side edges of the vane to cooperate during a specific period of time, as the only engagement dowels with the downstream support wall in order to take up said shearing forces, whereby tensile stresses will arise in the downstream end portion of the vane in the cross machine direction.

Abstract: The invention relates to a weapon whose main object is to attack targets, such as armoured tanks, from above unexpectedly. The weapon includes an active part (1), a propulsion unit, such as a launching device (2), an anchorage attachment (4) which is intended to be firmly anchored in relation to the terrain, and a line (3) whose first end (5) is attached to the active part (1) and whose second end (6) is pivotally attached to the anchorage attachment (4). When used, the active part (1) is launched vertically upwards, with the line (3) held taut, whereafter the active part is guided by the line through the air in a circular arcuate path or trajectory (8) to a target (7), with the centre of the arcuate trajectory in the anchorage attachment (4).
