Abstract: The invention relates to a coil-transporting carriage with adjustable retaining arms and to a method for the reliable handling of metal coils of small external diameter, or of sleeves, on a coiler mandrel. The coil-transporting carriage has a vertically displaceable coil saddle for accommodating a coil or a sleeve, also has two retaining arms for stabilizing the coil or the sleeve, the retaining arms being arranged opposite one another on the coil saddle and being pivotable by means of rotary drives, and additionally has a second drive unit for moving the coil-transporting carriage. For pulling off from a coiler mandrel, the coil saddle is positioned against a coil located on the coiler mandrel and the retaining arms are pivoted onto the coil. For pushing onto a coiler mandrel, first a sleeve is placed on the coil saddle of the coil-transporting carriage and is thereby guided by the retaining arms.

Abstract: According to the invention, a multilayer or insulating window pane (1) having at least two rigid panes (1P) and a spacer frame (1S) which connects these panes so as to form a tightly sealed intermediate space between the panes, and also an electrical component (3; for example motor, valve) which is arranged in the intermediate space between the panes, and also an associated electrical connection device is equipped with a detection device (4) for operating data of the component (3), which detection device cannot be manipulated from the outside but can be at least indirectly read off or read out. As a result, switch-on processes or times, maximum current consumption or operating temperature or the like, for example, can be detected and checked for servicing and/or monitoring purposes by reading out the operating data.

Abstract: A projection screen (1) made of a laminated glass which has at least two glass plates (3, 4) bonded to each other by means of a layer of plastic (2) is described. In order to create advantageous construction conditions, it is proposed that the glass plate (3) facing the projection bears on its outer side (6) a translucent ceramic coating extending at least over the projection area and that the glass plate (4) facing away from the projection preferably has a surface roughness preventing reflections.

Abstract: An attachment device for panes of glass. The attachment device includes retainers arranged between each pane and a support structure. The retainers include structures to compensate for the dimensional differences, deformations and displacements between the pane and the support structure. Degrees of freedom of rotation of the structure include uni-axis pivot joints. Strung together degrees of freedom in translation may be produced within the joints or by installing the joints in such a way that they can move. Panes can be mounted in a statically determinate manner by virtue of an appropriate combination of degrees of freedom.
