A dosing mechanism is equipped with a bulk material container such as a silo which has at least one movable or flexible wall portion that is moved to help in the discharge of the bulk material through a discharge device. The motion of the discharge device is transmitted directly to the movable wall portion by rigidly connecting the discharge device directly to the movable wall or wall portion and by movably mounting the discharge device below the silo.

Apparatus for the metered discharge of bulk material from a flexible

The run of a belt, such as a conveyor belt or a belt of a weighing scale, is monitored for keeping the belt in a substantially centered position. For this purpose, the belt has a marking element, and a stationary sensor is so arranged that it can scan at least two edges of the marking element. One marking edge extends perpendicularly to the belt running direction. The other marking edge extends at a slant or angle to the belt running direction. Thus, the sensor produces two marker signals at least one of which changes when the belt makes an off-center excursion. The two marker signals and a belt speed representing signal are processed in a computer to provide a belt deviation signal which may be used to correct the belt direction eitehr normally or automatically. The marking element has a triangular configuration and is so arranged that one side of the triangle extends substantially perpendicularly to the belt running direction.
