Abstract: A demolding device for use in an imprint machine, in which a foil is intermittently passed in a feed direction over a press region where a stamp is pressed against the foil for imprinting a surface pattern. The demolding device includes a carrier, a pressing roller mounted in the carrier, and a demolding roller mounted parallel to the pressing roller in the carrier, wherein the carrier is configured to slide over the press region against the feed direction while rolling the foil under the pressing roller and over the demolding roller for detaching the foil from the stamp after imprinting of the pattern.
Abstract: A modified kraft pulp fiber with unique properties is provided.

Abstract: A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements. Before heating of the elements, the flanges are gripped by a clamp which applies a resilient force which, during welding, causes the flanges to move toward each other and thereby a good weld joint is formed.
Abstract: Methods for reducing the effects of wetlapping, drying, and hornification of pulp fibers and consequently increasing the pulp drainage and strength properties in the final product (i.e., paper) are provided. The method which has been developed creates a “value-added” product by the wastepaper supplier or at the pulp and/or deinking (recycled paper) mill—a wastepaper load/bale, wet pulp stock or wet lap, or dried pulp treated with or impregnated with enzymes that enhance the quality of the pulp or paper product when it is repulped and processed at the paper mill.

Abstract: A cartomizer assembly of an electronic cigarette which is formed from automated assembly compatible parts comprises a container assembly including a container and a heater coil surrounding a wick in an airflow space of the container. The entire coil of the heater coil is inside the container and the heater coil is configured to heat liquid on the wick to generate an aerosol mist during a vaporization process. A liquid storage space is in liquid communication with the wick and is operable to supply liquid to the wick. The heater, the wick, and the container are shaped such that the heater and wick can be dropped into the container during automated assembly thereof and be directed to and located at a desired location in the container.
Abstract: The present invention relates to plant fiber processes (e.g., washing, drying, and/or grinding) that utilize recycle and/or make-up streams to use water resources efficiently and/or produce intermediate and/or final products with desired properties.
Abstract: The invention relates to a process for producing a dissolving pulp from a cellulosic starting material using the kraft process, comprising the step of cooking the starting material with a cooking liquor. The process according to the invention characterized in that the starting material is exposed to a steam treatment prior to cooking and that the pulp obtained by cooking is subjected to cold caustic extraction (CCE) in the course of further processing.

Abstract: A pharmaceutical composition and administration apparatus includes a portable powered vaporizer with a mouthpiece, smokeless vaporizing element, and a removable chamber. The chamber contains a composition comprising tetrahydrocannabinol (THC), cannabidiol (CBD), FCC grade ethanol, flavoring, pharmaceutical grade nicotine, USP grade aqueous glycerine, USP/EP grade propylene glycol, and USP grade vegetable glycerine. In various formulas the THC may be at concentrations of 1-30%, 30-60% and 60-99%, while CBD concentrations may be 0-15% including other cannabinoids derived from extraction.
Abstract: The disclosed solution relates to recovering thermal energy from the operation of a dissolver of a chemical recovery boiler used in pulp manufacturing. According to the solution, a primary fluid circuit conveys green liquor from the dissolver to an external process such as causticizing and solvent such as weak white liquor back to the dissolver, and from this circuit solvent is diverted into a secondary fluid passageway comprising a heat exchanger which cools the solvent by recovering heat from it and transfers the heat to a heat-consuming process. After heat recovery, solvent may be used for further processes before it is at least partly conveyed back to the dissolver.
Abstract: A manufacturing procedure for ceiling trims for vehicles. The ceiling trims comprise at least one first coating sheet and at least one second coating sheet that extend along one of the sides of the first sheet, joined via a layer of heat-stable polyurethane adhesive, comprising a step of applying a gas-phase catalyst on such sheets through a thermoforming mould that starts before the mould is completely closed and ends before the mould is completely opened. As a result of the application of a gas-phase catalyst we prevent the use of demoulding agents to facilitate extraction of the ceiling trim formed inside the mould.

Abstract: A recycled pulp that is reusable sanitary products is efficiently manufactured by recovering pulp fiber from used sanitary products containing the pulp fiber and a polymer absorbent. The method of the present invention comprises: a step applying a mechanical force to the used sanitary products in an aqueous solution containing a polyvalent metal ion or an acidic aqueous solution with a pH of 2.5 or lower and thus degrading the used sanitary products into the pulp fiber and other materials; a step separating the pulp fiber from the mixture of the pulp fiber and other materials that has been formed in the degradation step; and a step treating the pulp fiber thus separated with an ozone-containing aqueous solution with a pH of 2.5 or lower.
Abstract: Compositions comprising enzyme compositions are provided. Also provided are methods of treating virgin fiber and recycled wastepaper containing mineral oils using the compositions comprising enzyme compositions. The mineral oils generally originate from wastepapers with mineral oil based inks and certain other hydrocarbon-based chemistries used during the manufacturing, paperboard converting, and packaging process. The enzymes break down or modify mineral oils present in the fiber and paper, mobilize and liberate them from the fibers, and increase removal of mineral oils during paper recycling, pulping and papermaking processes. The method results in the break down or modification of mineral oil components in wastepaper, recycled pulp, and paper products by the enzyme compositions so that the mineral oils can be more efficiently detached and removed.
