Abstract: A folded blank for forming a display case and a display case formed from the folded blank. The folded blank comprises a one-piece blank including a first panel, a second panel, a third panel and a fourth panel connected in series at respective first, second and third vertical fold lines. The first panel is folded about the first vertical fold line and is engaged on a first portion of the second panel at a first manufacturer's joint strip. The fourth panel is folded about the third fold line and is engaged on the first panel at a second manufacturer's joint strip. The first portion forms a tear-away section defined by at least one separation line on the second panel. The first manufacturer's joint strip retains the tear-away section in engagement with the first panel during erection of the folded blank to form the display case having a display window.

Abstract: A foldable display comprising: a sleeve, two inserts spaced apart in an interior of the sleeve, and an elastic member comprising a first end coupled to one insert and a second end coupled to the other insert such that the elastic member extends between the two inserts. Each insert is coupled to an interior surface of the sleeve. When the display is in a collapsed position, the sleeve is in a flattened state and each insert is in a folded position that increases a distance between the two inserts. When the display is in a deployed position, each insert is in an unfolded position that decreases the distance between the two inserts. One or more sections of an outer perimeter of each insert contact one or more adjacent sections of the interior surface of the sleeve and bias the sleeve outward such that the sleeve forms a three-dimensional figure.

Abstract: A method for controlling a fiber fractionation system for fractionating an input material into a long fraction (LF) stream comprising LF fibers and a short fraction (SF) stream comprising SF fibers includes measuring an average LF fiber length at one or more locations post-fractionation, and maintaining the average LF fiber length within a target variability range by automatically altering a rotational speed of a rotor of the fiber fractionation system.

Abstract: Methods of forming crosslinked cellulose include mixing a crosslinking agent with cellulose mat fiber fragments composed of hydrogen-bonded cellulose fibers and having a solids content of about 45-95% to form a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers, drying the resulting mixture to 85-100% solids, then curing the dried mixture under conditions effective to crosslink the cellulose fibers. Some of such methods may include fragmenting a cellulose fiber mat to form the mat fragments. Systems include a mixing unit (such as a high-consistency mixer) configured to form, from the mat fragments and a crosslinking agent, a substantially homogenous mixture of non-crosslinked, individualized cellulose fibers and crosslinking agent, at ambient conditions, a drying unit to dry the substantially homogenous mixture to a consistency of 85-100%, and a curing unit and to cure the crosslinking agent to form dried and cured crosslinked cellulose fibers.

Abstract: A pallet-free bulk bin container comprises an open-ended bulk bin having a frame base at one end. A pair of channel inserts is configured to be engaged with the frame base to form pallet runners. A pair of center-filler supports is configured to enclose one end of the open-ended bulk bin. The bulk bin container may be shipped in a collapsed or knocked-down state and easily assembled into a larger container for use and being disassembled for re-use.

Abstract: Methods of producing clean (e.g., low sulfur and metal ion content, and free of fermentation inhibitors) sugar and lignin-rich streams, and downstream conversion products, from lignocellulosic biomass, may include obtaining non-chemically pretreated, milled lignocellulosic biomass, reacting the milled lignocellulosic biomass with an enzymatic agent to produce a slurry that includes converted monomeric lignocellulosic sugars and lignin-rich residuals, and separating the slurry into a sugar stream that includes the converted monomeric lignocellulosic sugars and a lignin-rich stream that includes the lignin-rich residuals. The sugar stream, not including water, includes at least 75% monomeric lignocellulosic sugar, less than 0.20% sulfur, and less than 3.0% metal ion content, and the lignin-rich stream includes at least 35% lignin and less than 0.50% sulfur. Some methods include producing fermentation products such as alcohols and/or organic acids from the sugar stream, and/or use of the lignin residuals in fuels.

Abstract: A pulp in accordance with a particular embodiment includes crosslinked cellulose fibers. The pulp can have high brightness, reactivity, and intrinsic viscosity. The pulp, therefore, can be well suited for use as a precursor in the production of low-color, high-viscosity cellulose derivatives. A method in accordance with a particular embodiment of the present technology includes forming a pulp from a cellulosic feedstock, bleaching the pulp, crosslinking cellulose fibers within the pulp while the pulp has a high consistency, and drying the pulp. The bleaching process can reduce a lignin content of the pulp to less than or equal to 0.09% by oven-dried weight of the crosslinked cellulose fibers. Crosslinking the cellulose fibers can include exposing the cellulose fibers to a glycidyl ether crosslinker having two or more glycidyl groups and a molecular weight per epoxide within a range from 140 to 175.
