Abstract: There is disclosed a device of an evacuation system, in particular a foldable evacuation means which is arranged to be lowered from a parked folded up position on the vessel to be evacuated to stretched out position on a rescue device, the bottom section of which including a weight device to keep the evacuation means sufficient extended in use position, an including a set of one or more cables/wires connected to a winch arrangement for lowering and lifting the evacuation means. The evacuation device is characterized in that the weight device is arranged to be positioned on the rescue device, and the system includes means to compensate for varying distances between the vessel to be evacuated and the rescue vessel.

Abstract: Bulk material is fed by a conveyor (10) into a hopper at the upper end of an upright extendible conduit (12). A fractionally opening gate (14) at the lower end of the conduit controls the rate at which the material in the conduit is discharged onto a discharge conveyor (15). Level sensors (13) detect the level of material in the hopper (18). A programmable logic controller (17) has its inputs connected to the sensors (13) and a belt weigher (11) associated with the conveyor (10), and controls the opening of the gate (14) to maintain a substantially full column of material in the conduit (12). The material discharged into the hopper (18) therefore moves slowly down the conduit in a controlled fashion, with minimal dust generation and product degradation.
