摘要： Apparatus for separating contaminant particles from liquid suspension stock, e.g. in the de-inking of used news print, is characterized by one or more of a plurality of features which contribute to increasing the capacity and effectiveness of the apparatus, including the provision of a cell comprising inner and outer annular chambers of substantially equal depth with the inlet and outlet connections for the stock being located adjacent the bottoms of the two chambers to force the stock to travel through the full depth of each chamber, and also the provision of a baffle of substantial width on the top of the wall between the two chambers to spread the stock overflowing that wall into a thin film. Other features include the use of an explosion-type flowbox to aerate the stock as it is delivered to froth flotation apparatus, and the provision of a variety of alternative constructions for spreading aerated grey stock into a film and causing that film to flow a substantial distance in a substantially horizontal plane in order to minimize the distance for travel of bubbles in the stock to the top of the film and thereby to expedite the resulting formation of a layer of froth at top of the film.

摘要： In screening apparatus for paper making stock comprising a cylindrical screening member dividing the interior of a pressure housing into a supply chamber and an accepts chamber, and also comprising a rotor mounted for rotation in the supply chamber and including a plurality of vanes mounted thereon in angularly spaced relation with each other and in relatively closely spaced relation with the screening member, each of the vanes is of generally airfoil shape and is oriented with its leading edge closest to the screening member and with the surface portion thereof trailing the leading edge diverging from the screening member to create a positive pressure force along the leading edge followed by a negative pressure force between the trailing portion and the screening member. A cap on each end of each vane extends radially outwardly from each end of the trailing portion of the vane and substantially closes the adjacent axial end of the space between the trailing portion of the vane and the screening member, and a bar is mounted on the trailing ends of each of these caps to define a slot extending along the trailing edge of the vane and leading directly from the space between the vane and the screening member to space on the radially inner side of the vane. This bar is located in more closely spaced relation with the screening member than the trailing portion of the vane to contain the negative pressure force developed by the vane within the space between the trailing portion of the vane and the opposed surface of the screening member.
