Die Erfindung betrifft eine Biegevorrichtung für Vier- oder Mehrwalzengerüste mit Arbeitswalzen, Stützwalzen und gegebenenfalls zwischen Arbeitswalzen und Stützwalzen angeordneten Zwischenwalzen, bei denen beidseitig an jedem Lagereinbaustück der Walzen Biegeblöcke angreifen, die in den Fenstern des Walzgerüstes vertikal geführt sind, wobei die sich jeweils vertikal gegenüberliegenden Biegeblöcke eines Walzenpaares über Kolben-Zylindereinheiten aufeinander zu- und voneinander weg bewegbar sind. Dabei greift an jedem Lagereinbaustück (5,6) beidseitig je ein zweiter vertikal verschiebbar geführter Biegeblock (16,17) an, der unabhängig von dem ersten Biegeblock (8,9) über eine sich am Walzenständer (7) abstützende Kolben-Zylinder-Einheit (18) bewegbar ist.

The invention relates to a conveyor system for sorting articles, specially parcels, packages or containers, composed of a conveying surface (1) with two longitudinal sides, defined by an array of conveying surface members (13) moving in the direction of conveyance (F1) having two diverting elements (14) on the sides mounted on the conveying surface members (13), which move transversely to the direction of conveyance (F1) across the conveying surface members (13) from one side of the conveying surface (1) to the other side; a guiding element (21) positioned on the diverting elements (14) and extending from the conveying surface (1), which is adapted to move the diverting element (14) along the conveying surface members (13) on a guide track (12a, b) and a diverting track (11, 15, 16, 20); a first diverting gate (25b) and a second diverting gate (25a) following the first one in the direction of conveyance (F1), which are positioned along the guide track (12a, b) and interrupt said guide track (12a, b), and which can adopt either a non-diverting position, in which the guiding element (21) moves along the guide track (12a, b) uninterrupted, or a diverting position, in which the guiding element (21) is diverted from the guide track (12a, b); a first diverting track (11, 16) meeting the first diverting gate (25b) and a second diverting track (15, 20) meeting the second diverting gate (25a), the first diverting track (11, 16) and the second diverting track (15, 20) being configured with respect to each other in such a way that the articles (3a-e) are diverted initially in an orientation parallel to the direction of conveyance (F1) and, subsequently, rotationally in the direction of diversion (F2).

A supporting arrangement for the conveyor belt in thin strip casting plants is disclosed. Liquid steel is cast on a revolving conveyor belt. The conveyor belt has at its bottom side arrangements for generating a negative pressure, for supporting and for cooling the belt. Rollers were hitherto used for supporting the belt. It could happen that the belt became curved between its supporting points on the roller. This is avoided by using supports whose mutual distance across the transport direction is larger than the length of the supports in that direction.

The invention relates to a pipe coupling with a cylindrical pipe, the smooth end portion of which can be introduced into a fitting having at least a sleeve-like area extending longitudinally and wherein a seal ring is mounted between the outer wall of the pipe and the inner wall of the fitting. The fitting and the pipe are firmly interconnected by means of a plastic deformable pressing tool acting externally at least on one radial plane of the sleeve-like area of the fitting and of the underlying pipe section. According to the invention, a metal bushing (31) that can be slid on to the fitting (1) by exerting force is mounted between the outer wall of the pipe and the inner wall of the fitting. The predetermined axial extension of the metal bushing (31) surrounds the pipe (2) from both front ends, the length of the metal bushing (31) being selected in such a way that it corresponds to the necessary overlap between the pipe (2.1, 2.2) and the fitting (1). This occurs when, after sliding the end portion of the pipe into the metal bushing (31) or inserting the fitting together with the metal bushing (31) previously slid into the end portion of the pipe, the front end (9, 10) of the end portion of the pipe facing the fitting (1) fits exactly on the marking made on the metal bushing (31) or on the stop, and the seal ring (32, 33) is diametrically traversed by the metal bushing (31).

A device for providing a seal between two contact parts (1, 2) movable in relation to each other, in particular between two valve flaps or a valve flap and a stop in a flue gas fitting, has an elastic sealing element (5) designed as a spring steel strip with two parallel and adjacent, flat clamping edges (6, 7) that face towards the same side and may be secured on one side by clamping means (9) to one contact part (1 or 2), as well as an arc-shaped sealing region (10). The sealing element (5) lies flat with a supporting surface located away from the clamping edges (6, 7) on the flat supporting surface (15) of a supporting element (8) that may also be secured by the clamping means (9) to one contact part (1 or 2). The other contact part (2 or 1) contacts the sealing element (5) at the apex of the curved sealing zone (10) and both contact parts (1, 2) move relatively to each other approximately tangentially to this apex. The supporting element (8) is arranged in the space enclosed by the curved sealing element (5).

Die Erfindung betrifft Seitenleisten einer verstellbaren Plattenkokille zum Stranggießen von Brammen, insbesondere für Stahl, die zwischen den Breitseiten der Kokille einklemmbar und mit einer dem Formraum abgekehrten Seite angeordneten Verstelleinrichtung verbunden und die an eine Kühlmittelzu- und -abfuhr angeschlossen sind. Dabei bestehen die Seitenleisten (21, 22) aus einem Wechsel- (23) und einem Halteteil (27), wobei jedes Wechselteil (23) aus Kupfer aufgebaut ist und eine U-förmige Gestalt besitzt, deren Schenkel (24) vom Formhohlraum 13 wegweisen, und wobei das Halteteil (27) in den Freiraum des U-förmigen Wechselteils (23) hineinragt und mit den Schenkeln (24) lösbar verbindbar ist.

Die Erfindung betrifft eine Vorrichtung zur Abdichtung von zwei Räumen unterschiedlichen Druckes über eine die Axialkräfte aufnehmende Schulter zwischen einem ersten warmgehenden metallischen Bauteil und mit einem radialen Spalt dazu angeordneten zweiten warmgehenden metallischen Bauteil, insbesondere Stator oder Gehäusedeckel und Gehäuse einer Turbomaschine, mit einer an der Schulter zur Anlage kommenden den radialen Spalt überdeckenden Dichtung. Erfindungsgemäß wird vorgeschlagen, daß die Dichtung aus einem einen etwa rechteckigen Querschnitt aufweisenden und axial verschiebbaren Tragelement (5) besteht, das ein im Tragelement (5) angeordnetes die der Schulter (7) zugewandte Seite (6) des Tragelementes (5) zur Anlage an der Schulter (7) bringendes Mittel (12) und ein den radialen Spalt (8) zwischen Tragelement (5) und einem Bauteil (2) überdeckendes Dichtelement (9) aufweist und die der Schulter (7) gegenüberliegende Seite (15) des Tragelementes (5) von dem einen höheren Druck p2 aufweisenden Raum (3) beaufschlagbar ist.
摘要:
A bottom electrode for an arc furnace operated with direct current consists of two parts made of different materials that may be joined to each other. One wearing part made of a material that is comparable to the molten mass is arranged in the area of the refractory lining of the furnace vessel bottom and one cooling part through which a cooling medium flows projects out of the furnace vessel. The invention is characterised in that the wearing part (22) is inserted in a cylindrical hole (15) arranged in the refractory lining (13) of the furnace vessel bottom (14). The face (23) of the wearing part (22) towards the inside (11) of the furnace vessel is spaced from the inner surface (16) of the furnace bottom (14) by a distance (a). A body (30) made of a refractory material is arranged in the free space (F) formed by face (23), inner surface (16) and the wall of the hole (15). The body (30) has a shape that brakes the movement of the molten mass (S) that flows around it during operation of the furnace.
