1. Apparatus for screening a fibrous suspension comprising a housing, a rotary screen mounted for rotation within said housing, said rotary screen including an upper end, a lower end, and a knob ring disposed at said lower end of said rotary screen, a screen chamber between said rotary screen and said housing including an inner surface defined by said rotary screen, an outer surface and a lower surface, an inlet for providing said fibrous suspension to said screen chamber, a reject outlet for withdrawing a reject portion of said fibrous suspension from said screen chamber, an accept outlet for withdrawing an accept portion of said fibrous suspension from said rotary screen, an outer screen chamber surface defining said outer surface of said screen chamber, a bottom screen chamber surface defining said lower surface of said screen chamber, a slot ring associated with said bottom screen chamber surface and adjacent to said knob ring defining a gap therebetween, and adjustment means for movably adjusting the location of said slot means whereby the size of said gap may be adjusted and said fibrous suspension may be substantially prevented from passing from said screen chamber through said gap, said adjustment means being at a location whereby said gap may be adjusted from outside of said housing.2. The apparatus of claim 1 wherein said adjustment means is attached to said bottom screen chamber surface.3. The apparatus of claim 2 wherein said adjustment means comprises a rotary screw attached to said slot ring and including threads having a predetermined pitch, and wherein said rotary screw and said slot ring are movable with respect to said bottom screen chamber surface.4. The apparatus of claim 1 including support means disposed at said bottom screen chamber surface within said screen chamber, said slot ring being fittingly attached to said support means, at least a portion of said support means being movable with said slot ring.5. The apparatus of claim 4 wherein said support means includes an outer support ring and wherein said at least a portion of said support means comprises an inner support ring.6. The apparatus of claim 5 wherein said support means extends over said entire bottom screen chamber surface.7. The apparatus of claim 6 wherein said outer support ring is detachable.8. The apparatus of claim 7 wherein said support means extends at least partially over said outer screen chamber surface.9. The apparatus of claim 6 wherein said reject outlet comprises a congruent opening in said bottom screen chamber surface, and wherein said outer support ring is rotary, whereby said congruent opening of said reject outlet is adjustable thereby.
