Abstract: Self-adhesive reinforcing material comprisinga) a UV-transparent plastic film to whichb) a woven fabric impregnated with a partially acrylate-modified epoxy resin is applied which, on the side facing away from the film a), is coated withc) a layer of an epoxy resin which again is partially acrylate-modified, the resins of b) and c) being converted by UV irradiation to a gelled state which can be further cured by heat, and containing a heat-activatable hardener component, andd) a release paper applied to the side opposite the film a), is very suitable for reinforcing sheet metal.

Abstract: Sizing agents, some of which are known compounds and some of which are novel aromatic compounds which contain in the aromatic nucleus a single hydrophobic substituent containing at least 5 carbon atoms and at least one anionic group, said hydrophobic substituent being linked to the aromatic nucleus through an ester, amide, urethane or urea bridge, with the CO group of ester and amide bridges being attached to the hydrophobic radical and a methylene group being optionally present between said bridges and the aromatic nucleus, are particularly suitable, together with commercially available retention aids, for use in a process for the mass sizing of paper or cardboard or for the surface sizing of paper.

Abstract: An apparatus is described, particularly suitable for skiers, for propelling a skier by the force of wind. The apparatus includes a parachute-like sail with the shroud lines of the sail connected to a harness worn by the skier. Control lines extend along the sides of the sail towards the harness to provide directional control. The shroud lines are attached to a special holding device between the sail and harness, which device is connected to the harness by a quick release lock.
