20100112243 | PAPER AND METHOD FOR MAKING PAPER - The invention relates to a paper that is formed of a fibre-based source material and is applicable as printing paper. According to the invention, the surface of the paper is surface-treated by arranging sufficient density on the surface, such that a mixture is arranged at least on one side of the surface of the paper for forming a surface layer, which mixture comprises pigments in an amount of 75-95% by weight of the dry weight and bonding agent in an amount of 5-25% by weight of the dry weight, and the porosity of the surface layer of the paper is less than 0.07 ml/g as defined by mercury porosimeter process. Furthermore, the invention relates to a method for making paper. | 05-06-2010 |
20100132902 | PAPER AND METHOD FOR MAKING PAPER - The invention relates to a paper that is formed of a fibre-based source material and is applicable as printing paper. According to the invention, the surface of the paper is surface-treated by arranging on the surface sufficient density in such manner that the density of at least one surface layer of the paper is sufficiently high to yield a Gurley-Hill value of over 7000 s/100 ml as measured from the entire paper. Furthermore, the invention relates to a method for making paper. | 06-03-2010 |

20130053457 | METHOD FOR NAPHTHALENE REMOVAL - A method for naphthalene removal from a gas using a solid adsorbent material including benzene for the removal. The removal can be applied to, for example, a crude syngas main stream and/or a carbon dioxide exhaust side stream. The adsorption to the adsorbent material can be reversible so that the material can be reused and naphthalene and possibly benzene can be recovered after regeneration. | 02-28-2013 |

20090283717 | Method for Preparing a Cellulose Carbamate Solution - A method for preparing a cellulose carbamate solution. Dissolving is performed in two steps, first by moistening cellulose carbamate pulp with a dilute alkaline solution and second by admixing a concentrated alkaline solution, as cold as possible, to the pulp under intensive stirring. The technique utilizes the low freezing point of the aqueous NaOH solution at the concentration of 18%, wherein the freezing point is below −20° C., and the intensive stirring function of the dissolve mixer device during the dosage. t is possible to prepare solutions of high quality and having high dry matter content in a mixing time of a few minutes only. | 11-19-2009 |
20130269546 | DISC PRESS - An apparatus for processing and compressing pulp, includes a circular perforated sieve base disc and at least one roll wheel circulating and rotating on the sieve base disc, where the sieve base disc and the at least one roll wheel rotating on the sieve base disc are shaped as bevel gears and make up a bevel gear assembly, by which the rotating force can be introduced in the gears of the bevel gear assembly to be partly converted to a compressive force for compressing the pulp to be processed through perforations in the bevel gear like sieve base disc. | 10-17-2013 |
