Abstract: In a process for making paper, paperboard and cardboard, paper pulps containing interfering materials are dehydrated in the presence of polymers which, as characteristic constituents, contain copolymerised units of the formulae … … with R and R = H or C1- to C3-alkyl, and have K values of at least 130, the polymers containing less than 10 mol% of units of formula II.

Abstract: The invention concerns aqueous pigment slurries containing, dispersed in them, up to 80% by wt. of a finely particulate pigment and 0.1 to 5% by wt. of dispersants. Such slurries are obtained by reacting (a) polyalkylene polyamines, polyamidoamines, ethylenimine-grafted polyamidoamines, polyether amines or mixtures of these compounds with (b) momoethylenically unsaturated carboxylic acids, salts, esters, amides or nitriles of monoethylenically unsaturated carboxylic acids, chlorocarboxylic acids and/or glycidyl compounds and optionally with (c) at least bifunctional cross-linking agents containing as the functional group a halohydrin, glycidyl, aziridin or isocyanate unit or a halogen atom to give water-soluable condensation products which have a viscosity, measured at 20.degree.C in 20% by wt. aqueous solution, of at least mPas. The invention also concerns a method of producing such aqueous pigment slurries by grinding or otherwise dispersing the pigments in the presence of the dispersants and water, and the use of the aqueous pigment slurries as additives to paper pulp in the manufacture of paper containing fillers.

Abstract: A flow-through cuvette (1), through which the sample flow (2) - surrounded by an enveloping flow (3) - is passed, is equipped with an optical laser measuring device (4-7). For use in systems under pressure, a pressure and quantity stabiliser (9-11) is connected upstream of the input (8) for the enveloping flow medium of the cuvette, and a controller (13, 14, 16, 17) for the quantity of the sample flow and enveloping flow is connected downstream of the output (12) of the cuvette.
