Abstract: The invention relates to a vane pump (1), in particular a regulatable oil pump for a lubricating system, with a pump housing (2) with at least one housing tank (6) and with a vane rotor (11) disposed in the housing tank (6) mounted so that it can be rotated by means of a drive shaft (10) in the pump housing (2) constituting an axis of rotation (23) which provides a mount for vanes (15) in approximately radially extending fitting slots (14). An adjusting ring (27) is provided enclosing the vane rotor (11) and circumferentially bounding pump cells (26) which, by means of a cylindrical internal wall surface (31), can be displaced between a concentric position with respect to the vane rotor (11) and an eccentric position relative thereto, to which pressured is applied by positioning torques caused by the medium pressure and a positioning mechanism (47) in order to regulate a pressure level.

Abstract: In order to be able to carry out a multiplicity of continuosly recurring activities at a continuous casting plant having at least one multifunction robot for implementing a plurality of different process-controlled or automated interventions at the continuous casting plant, at least one working region at the continuous casting plant and at least one multifunction robot assigned to each working region. The multifunction robot is arranged on a pivotable arm at a rotary column fastened to the pouring platform of the continuous casting plant and the robot can be pivoted with the pivot arm between a retraction position and a working position. The robot is also movable with respect to its arm.

Abstract: In the case of a strand guiding roller with at least one roller shell and with hat least two supporting shafts, two supporting shafts being respectively connected in a rotationally fixed manner to a roller shell and each supporting shaft being rotatably supported in a supporting bearing, to achieve a type of construction that is simple and can withstand the high thermal and mechanical loading that occurs, it is proposed that the roller shell is connected in a rotationally fixed manner to the supporting shafts carrying it on both sides by shrink-fit connections or by press-fit connections.

Abstract: A continuous casting installation is equipped with at least one robot for carrying out process-controlled or automated interventions on the continuous casting installation and accessing the assigned auxiliary devices.

Abstract: An internally cooled strand-guiding roll for a continuous casting installation, having a central rotatable shaft and at least one roll shell supported fixed against rotation on the shaft. To make the strand-guiding roll better able to withstand the mechanical and thermal stresses, to ensure that it is suitable for large strand widths and to enable maintenance work to be carried out, the roll shell has coolant passages passing through it, and the coolant passages are arranged in the roll shell at a constant distance from the cylindrical roll shell outer surface of the roll shell and preferably at the area between the shaft and the roll shell. It is preferable for at least one water guide ring to be arranged between the roll shell and the central shaft.

Abstract: Oil-in-water emulsions which contain (i) 100 parts by weight of a polydimethylsiloxane (P) having aminoalkyl groups and having an amine number of at least 0.1 meq/g of polydimethylsiloxane (P), composed of units of the general formula I R1aR2bSiO(4-a-b/2)??(I), in which R2 are aminoalkyl radials of the formula II —R3—NR4R5,??(II), (ii) protonating agent, (iii) water and (iv) not more than 5 parts by weight of emulsifier, are stable and provide for improved water repellency of porous and nonporous, absorptive and non-absorptive substrates treated therewith.

Abstract: An open-ended mold for casting metal strands with a thin slab cross section, the mold having broad-side walls which form a central widening region which extends from the mold inlet edge to the mold outlet edge and at the outlet edge opens out in a rectangular outlet cross section. To prevent to a great extent the strand from coming away from the broad-side walls, the contour of the mold cavity in the widening region is formed, as seen in sectional planes taken at right angles to the longitudinal axis of the mold, by curves which at least in partial regions form clothoids or clothoidal curves, within which sudden changes in curvature (&Dgr;k) are minimized or reduced to zero. The curvature reduces to flat at the mold outlet edge. Other cavity surface features are disclosed.

Abstract: A continuous casting mold for continuous casting of a steel billet. Opposite spaced apart wide side walls and opposite spaced apart narrow side walls between the wide side walls and clampable at the wide side walls and also displacable along the wide side walls transversely to the casting direction, the narrow side walls being narrow wedged-shaped in the casting direction. A funnel-shaped pouring-in region defined in the wide side walls. The wide side walls converge in the casting direction. The distance between the wide side walls at the mold end is constant over the entire width of the side walls allowing at least one of the wide side walls is supported to be displaceable and tiltable with respect to the other wide side wall by an adjusting device.

Abstract: In a continuous-casting apparatus with a mold-supporting device (4) and a mold (1) mounted to oscillate relative to the supporting device, the mold (1) is supported via guide elements (7, 10) extending approximately transversely to the direction of oscillation arranged approximately parallel to one another and, relative to the direction of oscillation (III), at a distance (12) one above the other. At least one first guide element (7) extends from the mold-supporting device (4) towards the mold (1) in a first direction (I) and at least one second guide element (10) extends from the mold-supporting device (4) towards the mold (I) in a direction (II) opposite to the first direction (I).

Abstract: The present invention provides polishes for surfaces, comprising aminoorganopolysiloxanes (A) which are solid at room temperature, contain fluoro groups and are able to change their aggregate state reversibly as a result of changes in temperature.

Abstract: In order to effectively stop noises in the interior of a vehicle occurring to relative movements between individual components or a component and associated support part, it is proposed to coat them with a lacquer at the contact points.

Abstract: A continuous casting mold for casting a strand has side walls defining an open-ended mold cavity. In order to increase the casting speed while maintaining a simple mode of construction of the continuous casting mold, the latter has the following characteristic features: at least two oppositely arranged side walls are rigidly fixed relative to each other about a pour-in section of the mold cavity and have a conicity decreasing in the running direction of the strand and, in a run-out section of the mold cavity arranged to follow the pour-in section in the running direction of the strand, include side wall sections movable relative to the strand and pressable at the strand by pressing devices, which side wall sections are arranged at a slighter conicity than the slightest conicity of the side walls of the pour-in section of the mold cavity.
