Abstract: The invention relates to a process and a device for the preparation of mixtures of liquids and/or solids, in particular for the preparation of polyol formulations for use in the preparation of polyurethanes.

Abstract: A new process for continuously preparing granules having narrow grain size distribution, comprising a) spraying the product to be granulated in liquid form into a fluidized bed, b) separating the proportions of fine material escaping from the fluidized bed from the off-gas and returning said fine material to the fluidized bed as nuclei for granule formation, c) setting the fluidizing gas flow such that granules are formed which are of a predetermined size, and d) removing the completed granules solely by way of at least one countercurrent gravity classifier inserted into the outflow bottom of the fluidized-bed vessel. A new apparatus for carrying out the process according to the invention and new granules.

Abstract: Impact-resistant sandwich structural elements containing at least one solid thermo-setting polyurethane layer and at least one polyurethane elastomer layer and a process for their preparation are disclosed. The elements are useful in preparing sanitary fittings, swimming pools, domestic refrigerators, wall panels, vehicles or furniture, in the construction industry, in waste-water technology or in coach-building.

Abstract: A multilayer flat molding with a visible side and a supporting layer, for example bathtubs or shower fittings, is described, the visible side consisting of a polyurethane surface coating layer and the supporting layer consisting of a reinforced polyurethane layer.

Abstract: For the production of sandwich structure elements comprising non-cellular polyurethane layers and polyurethane foamed layers which are produced on a substrate by the application of layers to a substrate, it is proposed that at least the non-cellular polyurethane layers contain 15 to 55% by weight of mica. Sandwich structure elements are obtained which are particularly dimensionally accurate and which adhere well. The effect is believed to be based on a non-homogeneous curing reaction of the mixture which reacts to form polyurethane, due to the presence of mica.

Abstract: A known herbicide such as a urea, carboxylic acid ester, aminoacid, benzoic acid derivative, benzonitrile, phenol derivative, diphenyl ether, carbamate, phenoxyalkanecarboxylic acid, triazine, triazinone, triazinedione, heterocycle, dipyridil derivative or benzosulphonamide, is rendered more effective by being combined with a synthetic spreading agent such as a silicone oil, fatty acid ester or fatty alcohol, e.g. isopropyl myristate, metamitron, ametridion or methabenzthiazuran.

Abstract: Novel oil-in-water emulsions, which contain(a) 0.1 to 80% by weight of at least one sparingly water-soluble active compound (as herein defined) selected from agrochemical active compounds, active compounds for combating pests in the domestic field and hygiene field and/or pharmacologically active compounds,(b) 1 to 20% by weight of at least one alkylaryl polyglycol ether of the general formula ##STR1## wherein R.sup.1 represents a hydrogen atom or an alkyl group having 1 to 16 carbon atoms,R.sup.3 represents a hydrogen atom or a methyl group,m is 1, 2 or 3, andn is an integer from 10 to 50,if appropriate in a mixture with an alkylarylsulphonic acid salt of the general formula ##STR2## wherein R.sup.3 represents an alkyl group having 8 to 35 carbon atoms andMe.sup..sym. represents an alkali metal cation, an equivalent of an alkaline earth metal cation or a cation of the general formula ##STR3## wherein R', R", R'" and R.sup.
