Abstract: Use of aqueous dispersions comprising at least one at least partially neutralized ethylene copolymer wax selected from among ethylene copolymer waxes which comprise, as comonomers in copolymerized form, (A) from 26.1 to 39% by weight of at least one ethylenically unsaturated carboxylic acid and (B) from 61 to 73.9% by weight of ethylene, and ethylene copolymer waxes which comprise, in copolymerized form, (A') from 20.5 to 38.9% by weight of at least one ethylenically unsaturated carboxylic acid, (B') from 60 to 79.4% by weight of ethylene and (C') from 0.1 to 15% by weight of at least one ethylenically unsaturated carboxylic ester, as auxiliaries for wastewater treatment.

Abstract: At least one magnetic-tape reel (2) can be moved by means of a conveying device (3) through a long cylindrical coil (1) (air-cored coil) which can be connected to a power source. In this case, the axis of the cylindrical coil is arranged transversely with respect to the plane of the reel, so that the magnetic lines of flux run transversely with respect to the tape reel.

Abstract: Acicular gamma-iron(III) oxide is manufactured by reacting an iron(II) salt solution with an aqueous solution of an alkali metal hydroxide and oxidizing the resulting suspension of iron(II) hydroxide in three stages. In a first stage, at most from 0.1 to 4% by weight of the amount of iron(II) hydroxide originally present is oxidized in the course of from 0.1 to 4 hours, in a second stage from 10 to 25% by weight of the said original amount are oxidized in the course of from 1.5 to 6 hours and in a third stage the remaining amount is oxidized. After the oxidation, the goethite formed is reduced to magnetite and the latter is then oxidized to acicular gamma-iron(III) oxide.
