Abstract: A process for improving the barrier properties of a barrier layer in a pulp-based substrate layer having a barrier layer, comprising the steps of providing a pulp-based substrate layer having a layer of an aqueous barrier composition applied to it, and then drying the pulp-based substrate layer having a layer of aqueous barrier composition applied to it to form a pulp-based substrate layer having a barrier layer, such that the moisture content of the pulp-based substrate layer having a barrier layer is below 2.5% by weight, preferably below 2% by weight, based on the weight of the pulp-based substrate layer having a barrier layer.

Abstract: The present invention provides for a dispersion containing cellulose particles dispersed in a continuous liquid phase comprising a first and a second continuous liquid phase, wherein the first continuous liquid phase consists of a liquid swelling agent or an aqueous solution of said liquid swelling agent, and the second continuous liquid phase comprises, preferably consists of, one or more organic solvents, with the proviso that the one or more organic solvents of the second continuous liquid phase are not capable of dissolving cellulose, have a boiling point higher than the boiling point of the first continuous liquid phase, and are miscible with the constituents of the swelling composition.

Abstract: A breathable absorbent article has at least one of a topsheet, an absorbent core, an optional distribution layer or a backsheet that comprises at least one to layer of a resilient, three dimensional liquid impervious polymeric film having apertures. The apertures form capillaries which are disposed at multiple directions, and/or have different diameters and lengths to create a response surface that is proportional to the pressure applied by the user's body, volume distribution of bodily fluid discharged by the user, the location of the discharge with respect to the position of the article, or a combination thereof, while the article is in use. The polymeric film can be formed by various processes, for example, vacuum forming or hydroforming methods.

Abstract: The reducing power of gases liberated at the top of the charge of an industrial furnace is determined by a method wherein the energy radiated from the charge in the range, for example between 1 and 6 microns, covering the radiant energy emitted by the compounds CO.sub.2, CO, H.sub.2, and CH.sub.4 is continuously measured in a multiplicity of detection points distributed over the entire upper surface of the charge and outputs are formed corresponding to the energy radiated at each of the points. An energy image of the energy radiated at the points in the range is formed from the outputs. This energy image is converted into respective specific images for the compounds by isolating from the energy image for each detection point the radiant energy emitted by the compounds. The concentration of each of the compounds at each of the points is calculated from the intensity of the respective specific image.

Abstract: Metallic sheets, wires, bars or other products are descaled by sweeping their surfaces with one or more laser beams to detach an adhering oxide film along lines traced by the beam sweep. The film fragments, still loosely adhering at locations between the sweep lines, are then removed mechanically, chemically or electrolytically.
