Sets of diametrically opposed ejection vanes are between the discs. One set has straight throwing faces. Another set has concave faces with a curvature axis inclined toward the plane of rotation at an acute angle greater than .alpha./2. A third set has curved faces inclined toward the other side of the plane of rotation.
