    • The present invention concerns a ballistic protection against objects such as projectiles from fire arms, alternatively scatter from for example hand grenades. The protection comprises an enclosure (1, 2, 4, 5, 6, 7, 9) adapted so that the object (10) can penetrate the enclosure (1, 2, 4, 5, 6, 7, 9) in at least one area (2); at least one intermediate layer (3) comprising granules (27) arranged within the enclosure (1, 2, 4, 5, 6, 7, 9), which intermediate layer (3) and enclosure (1, 2, 4, 5, 6, 7, 9) are arranged to decelerate said object (10). The invention is further characterized in that: the granules (27) are movable arranged with respect to each other; the space in the intermediate layer (3) that is not occupied by granules (27) is filled by a gas medium to enable contact between adjacent granules (27); the granules (27) have mechanical properties so that a granule (27) is crushed and spread in the intermediate layer (3) when it is hit by an object (10), at the same time as adjacent granules (27) are subjected to impulses with a subsequent energy dissipation so that the object and fragments thereof remains in the protection with a reduced risk for ricochets.
    • 本发明涉及对来自火臂的射弹等物体的防弹保护,或者例如手榴弹散射。 保护装置包括适于使物体(10)至少能够穿过外壳(1,2,4,5,6,7,9)的外壳(1,2,4,5,6,7,9),至少 一个区域(2); 至少一个中间层(3),其包括布置在所述外壳(1,2,4,5,6,7,9)内的颗粒(27),所述中间层(3)和外壳(1,2,3,4,5,9) 6,7,9)被布置成使所述物体(10)减速。 本发明的特征还在于:颗粒(27)相对于彼此可移动地布置; 未被颗粒(27)占据的中间层(3)中的空间被气体介质填充以使相邻的颗粒(27)能够接触; 颗粒(27)具有机械特性,使得当颗粒(27)被物体(10)撞击时,颗粒(27)被粉碎并扩散在中间层(3)中,同时相邻颗粒(27)经受 具有随后的能量耗散的脉冲,使得其物体和碎片保持在保护中,降低了引气的风险。

    • In an apparatus for dividing a suspension of fibrous cellulose pulp into a plurality of portions in a closed housing having multiple inlets and outlets, the present invention suggests that the closed housing is divided into two chambers, each provided with at least one inlet and at least one outlet, and that in the first chamber a separating device is arranged, rotating at high speed, to separate undesired parts from the suspension via an outlet, the inlet of the second chamber comprising an opening arranged between the first chamber and the second chamber to transfer the suspension which has been substantially freed from undesired parts. Furthermore in the second chamber a rotor provided with blades is arranged, the rotor being connected to the separating device in the first chamber, the separating device and rotor being driven by a common shaft, and a screening device cooperating with the rotor, to divide the suspension into different fractions which leave the second chamber by individual outlets.
