摘要： A chip pretreatment process which comprises conveying the feed material through a compression screw device having an atmosphere of saturated steam at a pressure above about 5 psig, decompressing and discharging the compressed material from the screw device into a decompression region, feeding the decompressed material from the decompression region into a fiberizing device, such as a low intensity disc refiner, where at least about 30 percent of the fiber bundles and fibers are axially separated, without substantial fibrillation of the fibers. In a more specific form the invention is directed to a process for producing mechanical pulp, including the steps of fiberizing wood chip feed material in a low intensity disc refiner until at least about 30 percent of the fibers are axially separated with less than about 5 percent fibrillation, and subsequently refining the fiberized material in a high intensity disc refiner until at least about 90 percent of the fibers are fibrillated. In another form the invention combines chip fiberizing with chemical treatments, for improving the pulp property versus energy relationships.

摘要： A system for thermomechanical refining of wood chips comprises preparing the chips for refining by exposing the chips to an environment of steam to soften the chips, compressively destructuring and dewatering the softened chips to a solids consistency above 55 percent, and diluting the destructured and dewatered chips to a consistency in the range of about 30 to 55 percent. The destructuring partially defibrates the material. This diluted material is fed to a rotating disc primary refiner wherein each of the opposed discs has an inner ring pattern of bars and grooves and an outer ring pattern of bars and grooves. The destructured and partially defibrated chips are substantially completely defibrated in the inner ring and the resulting fibers are fibrillated in the outer ring. The compressive destructuring, dewatering, and dilution can all be implemented in one integrated piece of equipment immediately upstream of the primary refiner, and the fiberizing and fibrillating are both achieved between only one set of relatively rotating discs in the primary refiner.

摘要： In an otherwise conventional star feeder, equipment longevity is greatly enhanced by providing a readily replaceable shear edge at the downstreammost (in the direction of rotor rotation) portion of the feeder housing inlet, adjacent the clearance between the rotating pocketed rotor and the housing. Preferably one or more plates defining the shear edge are mounted by fasteners, such as screw threaded fasteners, to the housing. Where the feeder is retrofit, with the replaceable shear edge, a recess may be formed in the housing to accept and position the one or more shear plates. A shear plate may have a number of openings elongated in a dimension intersecting the clearance adjacent the inlet, and by loosening or tightening fasteners the position of the plate shear edge may be adjusted with respect to the clearance to provide an effectively new shear edge when it becomes worn. At least the shear edge portion of the shear plate may be of a hard wear resistant material, e.g. having a Brinnell Hardness at least 10% greater than that of the housing, and between about 350-450. A removable protective baffle is preferably disposed in the inlet in a position above and protecting the shear edge.

摘要： A transportable floral holder in the nature of a wettable floral foam mass received within a water impervious shell, or sheath. The floral foam mass serves as a reservoir as well as a coupling device. The shell not only circumscribes the floral foam reservoir but also has oppositely disposed, open first and second ends. The open first end serves primarily to permit the cut stem bearing buds, blossoms and/or leaves to be inserted into a first implanting area of the floral foam mass so that the cut stem is provided with access to moisture that will extend the life of the attached buds, blossoms and/or leaves. The oppositely directed second open end of the shell primarily permits a bare cut stem to be inserted into a second implanting area of the floral foam mass, thereby allowing the shell encased floral foam mass to serve as a coupler that camouflages the fact that the stems have been cut so that the overall appearance of the floral presentation simulates an uncut, long stemmed bouquet in the nature of a sheaf that one can carry, or support, across the crook of an arm.

摘要： A method for refining lignocellulose-containing material into pulp in a disc refiner comprises preheating the material to a temperature greater than the glass transition temperature of lignin in the material, and holding this temperature for under one minute. The heated material is then subject to high speed refining in a disc refiner to produce pulp. The resulting pulp may then be subject to secondary refining steps to produce paper quality pulp. The preheat retention time is preferably in the range of 5-30 seconds, and can be controlled as a process variable to optimize energy savings, pulp strength, and optical qualities. High quality pulp can be obtained with preheat at high temperature and low retention time, followed by primary refining at disc speed of at least 2300 rpm.
