Abstract:
A device including a hollow body defining axially extending compartments therein for receiving a slurry of pulp fibers in a carrying flow. The device includes a stationary screen within the hollow body defining a slurry compartment on one side of the screen, and a screened compartment on the other side of the screen. The hollow body also includes a slurry inlet into the slurry compartment, an elutriation suction outlet in communication with the slurry inlet, and elutriation nozzles into the slurry compartment. The device also includes an elutriation pump outside of the hollow body, the elutriation suction outlet being in fluid communication the elutriation pump, and the elutriation pump being being in fluid communication with the elutriation nozzles.
Abstract:
A disc filter sector comprising a trapezium tubular support frame, and a trapezium screen frame supporting a screen cloth, the trapezium filter medium element being connected to the trapezium tubular support structure. More particularly, there is a pair of such filter sectors, and the sectors are connected together by an overlying cap.

Abstract:
A method of constructing a rotary drum filtering apparatus, the method comprising the steps of: placing a cover element end on a support portion, placing an overlying portion over the cover element end and inserting a respective tab into a respective opening in the support portion, moving the overlying portion along the support portion, so that the tab second portion is then under the support portion, thus holding the cap on the clip, with the cover element end trapped in between.
Abstract:
A web slitter assembly comprising a mechanism connected to a support structure and to a blade housing for holding the blade housing adjacent a band so that the side of a blade contacts the side of the band with an appropriate amount of force. The mechanism comprises a body connected to the support structure, and a pair of flexible walls spaced apart and on opposite sides of a portion of the body. The upper ends of the flexible walls are attached to the support structure, and the lower ends of the flexible walls are attached to the blade housing.

Abstract:
A disc segment adapted to be attached to other disc segments to form a disc assembly, the disc segment including an isosceles trapezoid frame. The frame comprises a left side rail and a right side rail, and a plurality of spaced apart parallel horizontally extending ribs connected between the side rails. The frame defines a first disc side and an opposite second disc side, each disc side including a corrugated left bottom clamp list adjacent the left side rail and supported by the ribs, and a corrugated right bottom clamp list adjacent the right side rail and supported by the ribs. Each disc side also includes a corrugated wire mesh supported by the left and right clamp lists, and supported by the frame ribs.
Abstract:
A cellulose nanofibrils production method comprising the steps of: identifying a desired level of cellulose nanofibrils pulp purity, partially refining pulp to produce a cellulose nanofibrils pulp purity between 5% and 15% less than the desired desired purity, and then separating out the cellulose nanofibrils from the longer fibers to produce the desired level of cellulose nanofibrils pulp purity.
