Abstract: The present invention discloses a composition that may be extruded or injection moulded, comprising a chemically modified hardwood lignin and a polyester. The chemically modified hardwood lignin constitutes 10 to 50 weight-% of the total weight of the composition.

Abstract: The present invention discloses a composition that may be extruded and/or injection moulded, comprising a chemically modified softwood lignin and a polyester selected from PBS (PolyButylene Succinate), PBAT (PolyButylene Adipate Terephthalate) and PCL (PolyCaproLactone) or mixtures thereof. The chemically modified softwood lignin constitutes 10 to 25 weight-% of the total weight of the composition.

Abstract: A personal service unit (PSU) includes a housing, a dial, and a flow control ring. The dial is rotatable about the housing. The housing includes a longitudinal axis therethrough and a first end and a second end opposite the first end. The dial includes a helical first portion along an interior wall of the dial. The flow control ring includes a helical second portion along an exterior wall of the flow control ring. The helical second portion rotatably mates with the helical first portion and rotation of the dial in a first direction moves the flow control ring in a first direction along the longitudinal axis to cause a first adjustment in airflow past the flow control ring and rotation of the flow control ring in an opposite direction moves the flow control ring in an opposite direction to cause a second adjustment in airflow past the flow control ring.

Abstract: A passenger seat for an aircraft, including a bottom support configured to be connected to a floor of the aircraft, a seat pan frame, and a support structure interconnecting the seat pan frame to the bottom support, the support structure including a front support member pivotally connected to a front end of the seat pan frame, the front support member including a respective strut on each side of the seat pan frame, each respective strut having a bottom end rigidly connected to the bottom support and an opposed top end located under the seat pan frame, the bottom end being inwardly, downwardly and rearwardly offset with respect to the top end.

Abstract: A polymeric material comprising a first polymer and a second polymer where the first polymer is a natural or a synthetic polymer and the second polymer is modified lignin. The modified lignin is modified with an alkyl containing group via linker wherein the linker is an ether group and wherein the alkyl containing group is derived from fatty acid methyl ester.

Abstract: The present invention relates to a method for the preparation of polymer shells, preferably composed of cellulose or hemicellulose, comprising the steps of dissolving the polymer component in a first solvent, preferably an organic solvent and precipitating the polymer component by contacting the first solution with a second solvent, which second solvent has a polar character, and in which second solvent the polymer component is essentially insoluble, thereby obtaining polymer shells. Moreover, the invention refers to the polymer shells as such, having permeable and responsive properties, as well as various applications comprising such polymer shells within the fields of drug delivery, separation techniques, and inter alia filling material.

Abstract: The invention relates to a process for making a purified lignin composition comprising a carrier liquid suitable for processing in a refinery. It comprises providing an aqueous lignin composition comprising lignin, cooking chemicals and water and adding a carrier liquid to the aqueous lignin to provide an organic phase. Then all or substantially all the water is removed from the composition. The lignin composition is processed to make the lignin more soluble in the carrier liquid in order to transfer more of the lignin to the organic phase. Cooking chemicals are removed, suitably by of washing by liquid/liquid extraction using a washing liquid. Finally washing liquid is removed.

Abstract: The present invention relates to a method of membrane-filtrating a lignin containing composition in order to obtain a lignin fraction more suitable for further treatments. In particular it relates to treating a liquid lignin composition to obtain a lignin fraction having a desired molecular weight distribution by a membrane filtration. It comprises subjecting the liquid lignin composition to a first membrane filtration with a first filter cut-off adapted to remove species having a first molecular weight thereby providing a permeate with a molecular weight distribution defined by said cut-off. Then, the permeate from the first membrane filtration is; subjected to at least one further filtration step with a second filter cut-off, different from said first filter cut-off to provide a retentate (concentrate) with a molecular weight distribution defined by both the cut-off in the first filter the cut-off in said second filter.
