The invention relates to a tensioning mechanism, comprising at least one tensioning element (1) which is surrounded by a protective covering (2). The tensioning (1) element has a rectangular or square cross-section so that it is possible to achieve a high pretensioning force with a small clamping element cross-section. An anchoring wedge (7) is provided for anchoring the inventive tensioning mechanism in an anchoring body. Said anchoring wedge is configured with a plane surface on the surface facing towards the tensioning mechanism (1) or tensioning elements.

The invention relates to an adhesive stick (1) for applying adhesive. Said stick comprises a cylindrical housing (2), which contains a propelling spindle (5), used to axially displace an elongated adhesive body. A twist grip (4), which is connected to the propelling spindle (5), is provided on one end of the housing (2). A casing (7), connected to the exterior of the twist grip (4), is rotatably mounted on the cylindrical housing (2). Said casing is designed to be at least partially transparent or perforated, so that the housing (2), which bears an imprint (14), is visible.

In order to transmit data flows via channels which respectively have several inputs and outputs, said data flows (d[n]) are respectively modulated at the channel inputs in a given manner to form transmission signals (s[n]), and corresponding data flows (d[n]) are derived at the channel outputs from the reception signals (x[n]) by equalization of distortion. A given matrix modulation structure (Mk) is imposed upon the data flows (d[n]) at the channel inputs and the equalization of distortion is carried out for the reception signals (x[n]) at the channel outputs on the basis of said known given matrix modulation.

To be able to utilize the kinetic energy which is due to the travelling speed of or the push-off energy introduced by the skier for a longer period than was possible with known skis, the invention provides for at least one of the lateral surfaces of the ski, notably the cross-country ski (SK), to be convex or parallel in the central area and concave in the front and/or rear area.

The invention relates to an electric installation device with a built-in component (5) which comprises electric components, such as current flow angle control components in the case of a dimmer, and an operating component (1) which is designed to be connected to the built-in component and comprises one or more actuating elements such as keys (8, 9) or setting controllers. The operating component can be connected to the built-in component (5) such that different electric connections (3, 4) are produced in at least two positions rotated in relation to each other, for example about 180 DEG . In the various positions of the operating component (1) the resulting different electrical connections permit different functions to be executed.

The invention relates to a method and a casting mould for producing a cast wheel-rim (1) from a light alloy by a casting process in a casting mould (8). At least one pre-formed foamed metal core piece (2) is introduced into the mould (8), fixed in position therein by means of positioning elements (7), e.g. pins and the light alloy (5) is subsequently cast around said piece. The method is characterized in that whilst the light alloy (5) is being cast around the core piece (2), gas which escapes from the core piece (2) as a result of the expansion associated with the heating of said piece is evacuated from the mould (8) through at least one ventilation passage (11) in said mould and in a positioning element (7).

The invention relates to a coupling for conductor bars. Said coupling (1) has a middle unit (2) which has two pivoting parts (13, 14) that pivot in relation to each other. A fixing device (3, 4) for a conductor bar (5) is provided on each of these pivoting parts (13, 14). Said fixing devices (3, 4) are provided with electrical connectors (15) for connecting to the conductor bars (5) to be placed on the fixing devices (3, 4). The individual connectors (15) belonging to the fixing devices (3, 4) are in the form of electroconductive rods which extend from the fixing devices (3, 4) into the inside of the pivoting parts of the middle unit (2). A conductor of one fixing device (3) rests slidingly on a conductor of the other fixing device (4), respectively. The connectors preferably each have a ring at their inner ends, a ring of one connector resting slidingly on a ring of another conductor respectively.
摘要:
Die Erfindung betrifft eine Texturierdüse zur Behandlung eines fadenförmigen Materials in einem zwischen mindestens zwei aufeinanderliegenden Grundkörpern (1) geformten Behandlungskanal (6) mit mindestens einem Düsenkörper (5) zur Zuführung eines gasförmigen Behandlungsmediums und zumindest einem Entlüftungsteil (8) im Behandlungskanal (6). Zur Erzielung einer leichten Herstellbarkeit, problemlosen Montage und einfachen Wartung sowie möglichst guter und symmetrischer Eigenschaften des herzustellenden Garns ist erfindungsgemäß vorgesehen, dass der Behandlungskanal (6) zumindest in Teilbereichen mit einem widerstandsfähigeren Material, z.B. Werkzeugstahl oder Keramik, als der Grundkörper (1) ausgebildet ist, beispielsweise als Einsatz (10) oder Aufsatz (11) vorgesehen ist. Für besonders gleichmäßigen Pfropfenaufbau und damit gleichmäßige Kräuselung bzw. symmetrische Garneigenschaften weist der Behandlungskanal (6) im Entlüftungsteil (8) quadratischen Querschnitt auf mit durch Lochbleche (12) od. dgl. gebildete Entlüftungsfenster an jeder Seite des Behandlungskanals (6).
