Abstract: A multi-part support element for spacing carrier elements, includes an upper part and a lower part, wherein the upper part can be detachably axially connected to the lower part by a rotary connection in order to fix a carrier element between the upper part and the lower part, the rotary connection is formed by a stud provided on the lower part and an opening provided on the upper part, into which the stud can be screwed, and the rotary connection is implemented such that the rotary connection is released again after defined screwing of the stud into the opening, such that the stud is locked in the opening with axial play, and wherein the lower part has a disk-shaped attachment, whose layer thickness decreases toward the edge.

Abstract: A roller for a roller furnace with a roller base body and a coating on the surface, wherein the coating has a first layer, containing: 10.0-30.0 wt.-% Si, 10.0-30.0 wt.-% Al(OH)3, 1.0-3.0 wt.-% B4C, 0.5-1.5 wt.-% Y2O3, 0.1-1.0 wt.-% Fe2O3 and the remainder Al2O3 and a second layer, containing 10.0-30.0 wt.-% Si, 10.0-30.0 wt.-% Al(OH)3, 1.0-3.0 wt.-% B4C, 2.0-4.0 wt.-% Y2O3 and the remainder Al2O3.

Abstract: A housing for a solar absorber module for a solar thermal power plant is described. The housing has a first tapered housing section with a first free end to accommodate a ceramic solar absorber element and a second end with a reduced cross-sectional area compared to the first end. The housing also has a second housing section with a cross-section substantially constant over its length. The second housing section is linked to the second end of the first housing section. A wall with a plurality of openings and extending across the entire internal cross-section of the first housing section is arranged in the first tapered housing section. A method for producing such housing is also described, as well as a method for fastening the housing to a support structure.

Abstract: A filter element, a particle filter, a method for marking a filter element, a method for producing a particle filter and the use of a filter element are described. With such methods and filter elements, individual filter elements can be securely adhered in a simple manner to form a filter. An identification means is applied to the end surfaces of each filter element for producing a particle filter, thus enabling the defined orientation of the filter elements for the adhesive process and preventing erroneous adhesion.

Abstract: A high-temperature-stable hollow profile is described. The hollow profile is provided with side walls and transverse walls. Wall thicknesses of the side walls and of the transverse walls increase in cross-section from a central region to a corner region of the hollow profile.

Abstract: A device for aligning and/or assembling filtering elements, in particular of particulate filter, an installation for assembling a filter from filtering elements incorporating the device, and a method for aligning and/or assembling monolithic filtering elements, in particular for making a particulate filter. The device includes a back plate whereon are set the filtering elements, the back plate being for example fixed on a base plate, and walls laterally foldable upwards by a folding mechanism, such that the filtering elements are mutually maintained tightly when the walls are in an upper position.
