Abstract: Conversion of organic educts, in particular biomass feedstock, into useful organic compounds via pyrolysis and bio-catalysts.

Abstract: An electric high-voltage insulator made from plastic comprises at least one glass fiber rod (1), at least one shield covering (2) made from silicone rubber which surrounds the glass fiber rod (1) and has concentric bulges (3) arranged along the longitudinal axis and bent in the shape of sheds in such a way that they form a convex top side and a concave or flat underside, as well as metal fittings (5) on both insulator ends. In this case, the bulges bent in the shape of sheds have at least one groove (4) on the underside preferably with a minimum depth of 1 mm.

Abstract: The invention relates to an electrical isolator having at least one fitting cemented onto an insulating body, in which the insulating body is bonded to the fitting via a cement shell, wherein a laminated layer which contains at least two layers of different materials is applied on the fitting between the cement shell and the fitting, wherein at least one of the layers protects the fitting from corrosion and wherein at least one other layer permits movement between the cement shell and the fitting.

Abstract: The invention relates to a high voltage insulator of ceramic material, which includes a longitudinal shank having molded sheds and to whose ends of the shank metal caps are shrink-fitted. The ends of the longitudinal shank are enlarged so that the diameter of the enlarged ends is at least 1.05 times the diameter of the longitudinal shank. The cylindrical surface, and the end face of the enlarged ends of the longitudinal shank are machined.

Abstract: An effective seal between the suspension mounting and the glass fiber rod of a compound high voltage insulator is obtained by filling the gap with a mixture of cross-linkable monomers or polymers formed from two or more reactive components, the mixture having a viscosity prior to cross-linking of less than 100,000 mPa.s and a penetration value between 1-500 mm/10 after cross linking. Particularly suitable are polymers based on polyorganodimethylsiloxanes.

Abstract: A process for continuous production of shaped bodies of synthetic resin reinforced with axially parallel fibers wherein a plurality of continuous fibers are drawn through spaced apertures in a perforated guide plate and then through an alternating series of impregnating baths and shaping nozzles and finally through a hardening zone. The impregnating baths, shaping nozzles, and drying zone are disposed in a vertical arrangement, the shaped body withdrawn from one shaping nozzle is passed with a further group of fibers through the next resin impregnating bath and shaping nozzle, the impregnating resin on the surface of the shaped body is still liquid as it enters the next impregnating bath and all of the impregnating baths and the drying zone are maintained at the same temperature. The resulting fiber-reinforced shaped synthetic resin bodies are particularly suitable as electrical insulators which also exhibit good mechanical strength and which are especially useful in high voltage installations.

Abstract: Open-air compound insulators are made treating a prefabricated glass-filter rod with silane, extruding a rubber layer on the rod, strengthening the rubber layer and bonding prefabricated screens to the rubber layer by vulcanization.

Abstract: An elongated electrical insulator has a supporting rod and barriers or screens spaced along the rod; an intermediate layer of material between the rod and the barriers or screens serves to exclude atmospheric moisture and other materials enhancing the electrical insulating characteristics of the insulator. The rod comprises a non-saponifiable resin reinforced with fiber glass of low alkali content. The barriers or screens comprise a non-saponifiable moisture-repellent polymer containing a filler. The intermediate layer comprises a moisture-repellent non-saponifiable polymer.
