摘要： An aqueous dispersion comprising particles of a zeolite having a hydrophobicity of below about 9.0 percent by weight residual butanol as determined by the Residual Butanol Test, which dispersion comprises a stabilizing amount of biogum. Production of the dispersion comprising mixing zeolite particles with a biogum into a dry mixture; and mixing the dry mixture with water under agitation into a homogeneous mixture. Use of the dispersion for binding particles of zeolite to fibers. Production of paper or paperboard by forming and dewatering a suspension of cellulosic fibers wherein dewatering is carried out in the presence of particles of a zeolite, the dispersion being added to the suspension prior to dewatering. Production of dry-laid paper, nonwoven or fluff pulp, in which cellulosic fibers are carried by a gas stream, in which the dispersion is sprayed onto the fibers while they are carried by the gas stream.

摘要： The invention relates to a method of embossing heat exchanger plates in several steps by a pressing tool, in that after a portion of the sheet blank has been embossed a subsequent portion of the blank is embossed, after this has been positioned and fixed in place between the punch and the die of the press. The positioning and clamping takes place in such a manner that a groove with zigzag extension pressed at the preceding embossing step in the sheet is caused to engage between a groove and, respectively, a bead arranged in the punch and the die which prior to the embossing are moved against each other and inside of the plane of the punch and, respectively, die by spring force.

摘要： The gasket grooves of plate elements are disposed in an intermediate plane. The gasket then will abut the distance members of both adjacent plate elements in its own gasket groove and parts of the respective distance members. The plate elements are fixed relative to each other when the plate elements are clamped together. The gaskets act as guide strips.
