Abstract: A telescopic edge protection post arrangeable between a floor and a ceiling, comprising outer and inner tubes, each comprising a bottom end and a top end, the inner tube extending into the outer tube and being movable with respect thereto between an extended position and a collapsed position. The post further comprises a locking mechanism to lock the inner tube with respect to the outer tube in the extended position, and a tensioning unit arranged at the top end of the inner tube. The tensioning unit comprises a tensioning element having a primary and secondary tensioning portions, wherein tensioning of the secondary tensioning portion requires a lower force than the primary tensioning portion, allowing tensioning of the secondary tensioning portion by extending the telescopic edge protection post by hand into engagement with the floor and the ceiling. Further, the primary and secondary tensioning portions each comprise a compression spring.

Abstract: A telescopic edge protection post arrangeable between a floor and a ceiling, wherein the telescopic edge protection post comprises an outer tube having a floor end and a top end, and an inner tube having a bottom end and a ceiling end. The inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position. The post further has a locking mechanism arranged to lock the inner tube with respect to the outer tube, and a tensioning device. The locking mechanism comprises a fixed element, which is attached to the outer tube at its top end, and a movable element, which is movable with respect to the fixed element between a locking position in which the movable element engages with the inner tube and the fixed element to prevent the inner tube from being retracted into the outer tube.

Abstract: There is provided a process for improving the quality of lignosulfonate at least partly derived form a spent sulfite cooking liquor in at least two steps, comprising: one step in which a lignosulfonate-containing fraction at least partly derived from the spent sulfite cooking liquor is subjected to filtration using a membrane having a cut-off of 40-150 kD (high cut-off) at the pressure, flow rate and temperature of the step and the permeate is recovered; and another step in which a lignosulfonate-containing fraction at least partly derived from the spent sulfite cooking liquor is subjected to filtration using a membrane having a cut-off of 1-20 kD (low cut-off) at the pressure, flow rate and temperature of the step and the retentate is recovered. Products, uses thereof as well as a system are also provided.

Abstract: An opening device for a flexible package having an opening portion defined by two side walls and a width, the opening device intended to be disposed in the opening portion of the package adjacent to an opening, formed upon initial opening of the package, for opening and closing thereof. The opening device comprises a thin-walled first body with a contact surface and a first application surface opposite thereto for allowing application of the first body in the opening portion to a first of the two side walls. The first body is maneuverable, by folding about a first folding axis, between a basic position and a sealing position. In the sealing position, the contact surface has sub portions directly facing each other. A locking member is designed for releasable locking of the body in the sealing position.

Abstract: The preset invention relates to a method, use of the method and a device for making a seal in a portion of a material web. The material web includes a first elongate section with a first number of layers of material and a second elongate section with a second number of layers of material, at least one of the layers of material being included in both the first and the second section, the portion having an extent that intersects a transition from the first section to the second section of the material web, the method including connecting, in the portion, opposite surfaces of the layers of material of the material web to each other. The method including forming ridges and valleys in the portion, and orienting the ridges and valleys in such a manner that they have an extent intersecting the transition.
