Abstract: A casting apparatus for manufacturing polymer film includes a die for discharging a molten polymer and having discharge direction oriented at a discharge angle offset from horizontal. The apparatus includes a first chill roll having a first diameter and a second chill roll having a second greater diameter. There is a first gap between the first chill roll and the second chill roll. The discharge angle is of a predetermined magnitude to gravity assist delivery of the molten polymer to the first gap. The second chill roll is positioned to gravity support the film exiting the first gap along a first length of a first side of the film. A first polishing roll is positioned downstream first and second chill rolls. The first polishing roll engages and cools a second length of a second opposite side of the film. The first length is substantially equal to the second length.

Abstract: A film casting apparatus includes a die which has a non-zero angled discharge direction relative to a horizontal plane. A chill roll is positioned downstream of the die. A film displacement device is positioned proximate to the chill roll and is configured to position the molten polymer on the chill roll and establish the thickness of the film. The non-zero discharge angle is of a predetermined magnitude to gravity assist delivery of the molten polymer to the chill roll. The chill roll is positioned to gravity support the polymer film along a first length of a first side of the polymer film. A first polishing roll is positioned downstream of the chill roll and engages and cools a second length of a second side of the polymer film which is opposite the first side. The first length is substantially equal to the second length.

Abstract: The present invention is directed to a method for scouring and increasing the brightness of non-wood fibers. The method comprises forming a mixture of non-wood fibers, exposing the mixture to a scouring liquor and a scouring agent comprising oxygen gas to form a scouring mixture, and scouring the scouring mixture by radially circulating the scouring liquor throughout the scouring mixture to provide scoured fibers.

Abstract: A renewable fuel may be obtained from a bio-oil containing C3-C5 oxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C6+ oxygenates. In a second step, the stream is hydrotreated to produce C6+ hydrocarbons.

Abstract: In a winder assembly, a turret assembly indexes first and second cores between winding and removal positions. A lay-on roll assembly includes a roller and moves between a retracted position and an engaged position wherein the roller and the core, or the work material wound onto the core, cooperate to form a nip. A cutter is provided for cutting a web of sheet-type work material being wound onto the core. An enveloper assembly is provided and includes a nipping pivot roller that can engage a cut edge of the work material and feed the cut edge into the nip formed between the roller forming part of the lay-on roll assembly and a fresh core thereby allowing the work material to wind around the core.
