Abstract: A front-loading poster frame assembly is disclosed with molded corner frame members positioned between adjacent frame sections. The corner frame members securely attach together the base portions of adjacent frame sections. The cover portions are mitered at the corners and hinged to the base portions. Interference members are situated in openings in the hinge pintle members on the base portions and prevent the cover portions from relative longitudinal movement.

Abstract: The present invention solves the problem of managing resin-containing waste liquors within the cellulose pulp industry. The invention relates to a method for purifying resin-containing waste liquor in the manufacture of cellulose pulp, in which method a pH-adjusting chemical is, when necessary, added to resin-containing waste liquor removed from the cellulose pulps, so that the pH of the waste liquor will lie within the pH range 1-7, and in which a water-soluble organic polymer is added to the waste liquor in the form of a forwardly moving liquid stream. The method is characterized by dividing up the requisite amount of polymer into part quantities which are introduced into the liquid stream on at least two occasions, by subjecting the liquid stream to a pronounced shearing and/or turbulent treatment process, and by subsequently separating agglomerated resin from the waste liquor.
