Abstract: A device (70) for evacuating people from a building is provided with a rescue member via which people can be brought from an upper storey of the building (2) to ground level (28). The rescue member has at least one rope (20), belt or similar, which is let down from the upper storey of the building (2) along the building wall to ground level (28). At specified intervals on this rope (20), support members (31) are arranged with which, in each of the storeys, a carrying element (32) can be connected, on which at least one person is held. The carrying elements (32) are automatically detachable in an area close to ground level (28). This device (7?) enables people to be evacuated safely and easily.

Abstract: The apparatus comprises a plurality of stages having screw presses, the material passing out from the outlet side of the stages being passed by a transfer duct to the inlet side of the following stage. Each stage has a speed adjustable independently of the speed of the other stages. Compared with known screw presses, the advantage exists that following each treatment in a stage, by means of an opening in the transfer duct, the material can be measured, checked or subjected to an additional treatment. The number of stages can also be adapted to the material being processed and there is also a relatively large freedom with regards to the arrangement of the apparatus.

Abstract: The collision protection device comprises a collision protector held in a rest position by spring force. Upon collision against an obstacle, the collision protector is displaced against the spring force and thus cooperates with a de-energizing device. This collision protector is mounted on the vehicle chassis by two swing arms arranged symmetrically non-parallel or in angled relationship to the longitudinal axis of the vehicle. This is to permit the de-energizing device to function effectively, irrespective of the place of impact of the obstacle against the collision protector and irrespective of any deformation of the collision protector. Each swing arm is pivotably mounted on the collision protector and on a sliding link member. Each sliding link member is acted upon by the spring force and is displaceably positioned on a cross-shaft mounted on the vehicle chassis perpendicular to the longitudinal axis of the vehicle.
