Abstract
The connecting duct which directs the flock-laden air stream into the chute is provided with a restriction as well as with a ring duct for directing air impulses into the duct via openings on opposite sides of the duct. The restriction causes the air stream to accelerate and, since the air flow is closer to one opening, rather than the other, a reduced pressure is created on that side. This, in turn, causes a pulse of air to travel from one end of the ring duct to the other. The air pulse continues into the connecting duct to deflect the flock-laden air stream towards the other opening. This sequence then continues in rapid fashion to allow an even deposit of the flock in the chute.
