A spreading anchor (1) including an anchor rod (2) provided at its front end, when viewed in a setting direction, with a head (3, 30) having at least several regions, which taper outwardly in the setting direction, and extending through an axial through-bore of an expansion sleeve(5) axially displaceable along the anchor rod (2, 20) and having a plurality of axial longitudinal slots (7) extending from a front end of the expansion sleeve (2, 20) and forming at least two, located opposite each other expansion tabs (6) provided at their free front ends with cutters (16), the spreading anchor (1) being supported against an upper surface of a ground (G) and further including rotation-transmitting driver elements for transmitting axial rotation, which is generated during setting of the anchor rod (2, 20), to the expansion sleeve (5).
摘要:
A precision vacuum melting and casting furnace with a melting chamber containing a melting device. A casting chamber is positioned below the melting chamber. The casting chamber can be raised, lowered, and swung out to the side. The casting chamber communicates with the melting chamber through a valve chamber, which contains a vacuum valve. The valve chamber accommodates a lift platform for raising the mold up under the melting device. The casting chamber has a lifting mechanism, and the vacuum valve has an activating rod. In order to essentially simplify precise alignment of the different movable parts and to convert an existing conventional casting furnace into a furnace in accordance with the present invention, a hollow vertical shaft is attached to the valve chamber. The rod that activates the vacuum valve extends vacuum-tight through the shaft. A sleeve that guides the casting chamber is positioned at the outer surface of the shaft.

A plastic substrate is disclosed that is provided with a conductive layer wherein an electroluminescent layer is applied to a conductive layer. In order to produce the electroluminescent layer, a printing paste is used that is preferably applied by means of screen printing. The printing paste is based on a transparent, acrylate-based UV printing lacquer that is known per se. The UV printing lacquer is mixed with electroluminophores at a ratio of at least two parts by weight UV printing lacquer and three parts by weight electroluminophores. A phthalic acid emollient is added. The dielectric layer results from the application, preferably the imprinting, of a dielectric paste. Preferably, a composition is selected from the dielectric paste that is similar to that of the printing paste. Here, however, instead of the luminescent pigments, a filler is used, preferably a mixture of barium titanate and titanium dioxide. The back electrode may advantageously be produced by applying (preferably using pressure) a silver conductor paste already used for conventional electroluminescent elements.

The electroluminescent (EL) element comprises a transparent plastic film substrate (1) onto whose rear side a transparent first electrode layer (2) comprised of indium tin oxide (ITO) is vacuum sputtered. A first electroluminescent layer (3) with dispersed electroluminophores (4) is placed on the first electrode layer (2). This first electroluminescent layer consists of a transparent matrix (5) into which the electroluminophores (4) are incorporated (4). The second electrode layer (rear electrode layer) (6) is placed on the first electroluminescent layer (3) or on an insulating intermediate layer (not shown) located thereon. This second electrode layer is insulated toward its side facing away from the first electroluminescent layer (3) by means of the insulating layer (7). On the front side, i.e. the visible face, a third electrode layer (8) comprised of transparent conductive lacquer is applied to the plastic film substrate (1). A second electroluminescent layer (9) with dispersed electroluminophores (4) is placed on the third electrode layer (8). The fourth electrode layer (10) comprised of transparent conductive lacquer is placed on said second electroluminescent layer (9) or on an insulating intermediate layer (not shown) located thereon. This fourth electrode layer (10) is insulated on the visible face by means of an insulating layer (11).

A device is provided which is usable to draw at least one web of material or at least one web strand, that includes several webs of material, into a folding apparatus. The folding apparatus includes at least an upper structure, at least one folding funnel and a cross cutting device for separating the web of material, which has been transported in the upper structure and folded on the folding funnel, into individual products. At least one guide rail is provided. A holding part with a guiding end of at least one web of material fixed thereto, is displaceably guided on a path of web travel of the web through the upper structure. At least one guide rail is provided along the folding funnel.

The invention relates to an electroluminescent film providing a particularly advantageous compromise between the safe functioning and simplified production thereof. The inventive polychromatic electroluminescent element consists of three similar electroluminescent films which contain dispersed electroluminophors and whose colors are not different from each other. The different colors are obtainable by an additional color mixture by means of a separate electric excitation of each electroluminescent film. Each of the films essentially comprises a support made of PET or other plastic material on which an electrode layer is vapour-deposited or cathode-sputtered, a luminous layer on which a rear transparent electrode is placed by serigraphy and laminated by means of an insulating foil.

Lifting mechanism for casting molds in precision founding furnaces with a melting facility disposed in a melting chamber and a transfer chamber disposed below the melting chamber. The lifting mechanism has a mold table centrally disposed below the casting mold with a lifting rod and a vertical guiding mechanism. The driving mechanism for the lifting rod comprises a rapid driving mechanism and a precision driving mechanism which is connected in series with the rapid driving mechanism. At the vertical guiding mechanism, a carriage is guided, which can be moved by the rapid driving mechanism into at least two specifiable positions. The precision driving mechanism is mounted on the carriage and can be raised and lowered together with said carriage and is connected to the lifting rod of the mold table.
摘要:
For the distillation of a stream consisting essentially of alcohols of 6-20 carbon atoms, water and methanol, the methanol is first separated from the homogeneous, aqueous solution as the overhead product by distillation under a head pressure of 500-1,000 mbar. The bottoms discharge is mechanically separated under normal pressure and at a temperature of 5.degree.-95.degree. C. in a phase separator to obtain a discrete water phase preferably containing at least two thirds of the feedstream water. The remaining organic phase is then transferred from the phase separator into a second distillation column and the organic phase is dewatered in the latter at 100-500 mbar. The head product from the second column is conducted to a second phase separator; the aqueous phase is separated therein at a temperature of 5.degree.-95.degree. C. and optionally returned into the first phase separator. The bottom product from the second distillation column is passed into a downstream distillation stage wherein the C.sub.6 to C.sub.20 alcohols are separated into fractions thereof.
