Abstract: Electrorheological fluids have been developed which essentially contain an aluminium-free metal silicate hydrate possessing a sheet structure, a dispersant and an inert aprotic dispersion medium. The metal silicate hydrate is preferably of the kenyaite, magadiite and/or kanemite type. The dispersion medium is preferably a silicone oil having a viscosity range from 0.5 to 1,000 mPas or a mineral oil or a paraffin oil having a viscosity range from 0.1 to 1,000 mPas. The metal silicate hydrate is added to the electrorheological fluid in a concentration of from 1 to 50% by weight.

Abstract: A process and an apparatus for the planarizing of rough, structured or heterogeneous surfaces with a leveling layer. A cover layer permeable to energy radiation is laminated by means of a film pressing device, which comprises a sliding shoe and a feed device, on to a substrate base bearing the surface to be planarized. During lamination, the contact zone between the film pressing device and the substrate base forms a tapering laminating nip, which is constantly supplied with the organic coating material forming a film or layer.

Abstract: In process and assembly to separate trioxane from a mixture of liquids also containing water and formaldehyde, the novelty is that the mixture is first distilled at low pressure and the resulting distillate is then distilled again at a higher pressure to produce trioxane as the sump residue. The lower pressure and the higher pressure are in the range 0.1 to 20 bar (absolute), pref. approx. 0.5 bar for the lower pressure and approx. 6 bar for the higher pressure. Further claimed is that the trioxane is subsequently used as a disinfectant or for the production of polyoxymethylenes or polyvalent alcohols. A suitable assembly incorporates two distillation columns linked in series in which the head of the first is linked to the central section of the second, and the head of the second column is linked to the central section of the first.
