METHOD AND DEVICE FOR CONTROLLING VELOCITY PROFILE AT THE OUTLET OF DISPENSING COLLECTOR Russian patent published in 1995 - IPC

FIELD: power and chemical mechanical engineering. SUBSTANCE: flowing section of passages 3 of dispensing grid 2 are changed due to movement of movable members 5 inside them. The resultant force of gravity and drag applied to the members serves as a control action. The flowing section of each passageway 3 decreases in the direction of its outlet. The inlet part is provided with movable member 5 and bearing parts arresting reciprocation of the member in passageway. EFFECT: improved accuracy of controlling. 3 cl, 6 dwg
