摘要:
A filter arrangement, for cleaning gases contaminated with particles, has at least one filter unit with an exterior and an interior filter (3.1, 3.2), wherein the exterior and interior filters can be moved relative to each other, thereby exposing an opening (3.4) in the bottom regions thereof. This allows cleaning of filter units at the site of the filter units without disassembly of the same (cleaning in place—CIP). A method for cleaning is provided in that the region of the filter unit on the clean gas side including introducing a fluid sprayed via a cleaning lance protruding into the clean gas region while exposing a gap (3.4) in the bottom region of the exterior and interior filters.
摘要:
A low-emissivity multilayer system highly resistant to heat treatment for transparent substrates, in particular for window panes comprises, starting from the substrate, at least a lower antireflection coating consisting of several partial layers and including a layer essentially consisting of ZnO which is adjacent with a silver-based functional layer, an essentially metallic blocking layer located on top of the silver-based layer, an upper antireflection coating consisting of several partial layers and a cover coating optionally consisting of several partial layers. The upper antireflection coating has: a partial layer of ZnO or a mixed oxide ZnMeOx that contains ZnO or a succession of layers of mixed oxides of the ZnO:Al/ZnMeOx type; a partial layer of Si3N4 or SixOyNz; and between these two partial layers, a separating layer with a thickness of 0.5 to 5 nm, consisting of a metal oxide or a mixed oxide with a cubic crystal lattice, which prevents direct contact between these two partial layers. According to the invention, the inserted separating layer makes it possible to further improve the mechanical and chemical properties of the multilayer system and to obtain coated window panes that are highly resistant to technical handling operations.

摘要:
A bearing arrangement (4) is provided with a bearing inner bush (10) and an outer bush (5), especially for the central joint (1) of a Watt's linkage. The bearing arrangement (4) is provided with a sealing arrangement (12) surrounding the front-side bearing gap between the inner bush (10) and the outer bush (5). The sealing arrangement (12) comprises an elastic sealing element (14) with static as well as dynamic sealing surfaces. The bearing arrangement (4) has a sealing arrangement (12) designed as a sealing module (12), which can be connected to the bearing inner bush (10), the sealing module (12) also comprising a running surface (15) for the axial bearing of the outer bush (5). The arrangement makes possible the especially economical production of modularly designed, highly loadable bush bearings. Furthermore, undivided, continuous bearing bushes can be used, which improves the ability to be mounted and the precision and the service life of the bearing arrangement. It is also possible, especially in case of highly stressed bush bearings, to dimension the axial rigidity as well as the radial rigidity of the bearing arrangement independently from one another, and especially good sealing is obtained against environmental effects.
摘要:
A layer stack for the surface coating of transparent substrates, in particular panes of glass, has at least one metal oxide composite layer produced by reactive cathodic sputtering and contains Zn oxide and Sn oxide. Relative to the total amount of metal, this metal oxide composite layer contains from 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge, Si, P, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta. In a layer stack which has a silver layer as a functional layer, the metal oxide composite layer may be used as an upper and/or lower antireflection layer, as a diffusion barrier layer, as a sublayer of an antireflection layer and/or as an upper cover layer.
