Abstract: A process for producing paper of high basis weight by draining a paper pulp on a wire in the presence of a combination of at least two polymers as a retention and drainage aid system, forming sheets, and drying the sheets, which comprises forming the sheets in the absence of finely divided inorganic flocculants and using as retention and drainage aids (a) at least one amino-containing polymer and (b) at least one branched cationic polyacrylamide.

Abstract: A container, in particular a container provided for transporting goods, said container being formed by at least two elements (20-1), (20-2) each comprising a base part and side walls, said base parts being formed by a set-up of fingers (21,22) and grooves (23,24) mounted in such a manner that the fingers (21,22) of one base part engage into the grooves (23,24) of another base part, thereby enabling a telescopic engagement of the base parts in order to adapt the container's width, whereby the fingers (21,22) of one of the base parts have at their edges, facing their respective groove, each time an essentially C-shaped profile (27) in which is housed a wheel (28), said wheel (28) being mounted on an axle (31) fixed on a finger of another base part, and wherein each base part is provided with a cover plate (2) extending within a volume delimited by said side walls, one of said cover plates (2) forming a top cover plate and the other cover plates being mounted in such a manner that they shift underneath said top
