Abstract: A device for fastening objects on an exterior surface of a building or an object, the device having a carrying part and a covering part. The carrying part has the function of statically supporting the object to be fastened, and the covering part has the function of sealing the object to be fastened with respect to the exterior surface of the building or object and is arranged for that purpose on the exterior side of the exterior surface of the building or object. Connecting parts for the object to be fastened protrude from the carrying part through openings in the covering part. The covering part is a dimensionally stable body and the relative position of the covering part with respect to the carrying part can be adjusted in the direction perpendicular to the building or object surface.

Abstract: An electric melting furnace arrangement for the continuous melting of spinnable mineral fine-particle or granular materials has a refractorily lined furnace vessel, a plurality of electrodes arranged on a partial circle extending into the furnace vessel from above, conveying devices for the materials to be melted designed as dosing pipes arranged close to the partial circle formed by the electrodes and each provided between two electrodes and a tapping device penetrating a side wall of the furnace vessel. Transporting devices are provided for admitting the dosing pipes, and when the dosing pipes are completely full, the further conveying of the materials to be melted is interruptable.

Abstract: A tilting channel for guiding molten material includes a trough-shaped channel body provided with outlets at opposite ends thereof and a spot of impact for the jet of molten material between said outlets. The channel body is pivotable by means of a pivot drive about a tilting axle from a normal operation position into an emergency operation position, and vice versa. The channel body is formed by two channel parts enclosing an angle O<.phi.<180.degree., and the bottom of the first channel part is arranged at a lower level relative to the bottom of the second channel part. The spot of impact of the jet is located on the first channel part close to where the latter enters into the second channel part, and the vertical middle plane of the first channel part lies in the plane formed by the jet, when the first channel part is in its downwardly inclined normal operating position.

Abstract: Electric furnace arrangement including a furnace vessel with liftable and lowerable lid penetrated by at least one electrode. The electrode is fastened to a liftable and lowerable supporting construction by first clamping devices. For lifting the lid, a further clamping device for the electrode is provided on the lid, at least one coupling element is provided on the supporting construction and at least one counter-coupling element is arranged on the lid, which can be brought into and out of engagement with the coupling element. A connecting element can be provided between coupling element and supporting construction.
