摘要:
A method for lining chambers and galleries, especially mining and tunnelling galleries, employs resilient steel supporting frames which consist of a number of box-like section segments capable of being slid one into another and which thus, at least in the zone of overlap, constitute a closed tube. The ends of the overlapping segments are widened or compressed, as the case may be, and then inserted one into another. Each overlapping outer section segment is then mechanically compressed in the region of the overlap until ears of the so compressed segment grip behind flanges of the overlapped inner section segment. A self-locking wedge system providing means of restraint or braking is inserted between each two overlapping outer and inner section segments, and a leading tie and a deformation tie are fitted at the overlap region to the respective ends of the overlapping outer and inner section segments.

A profile steel of an about U-shaped cross section, which has a profile bottom with webs and flanges slightly inclined toward each other and extending in the direction toward the open profile side. This profile steel, which is particularly well suited as profile steel segment when preparing reinforcing frames in connection with the building of mine shafts and tunnels, has a profile bottom which at its longitudinal sides has steps directed to the open side of the profile. These steps merge with the above mentioned webs which in their turn at the ends remote from the steps end in flanges pointing toward each other.

A tablet for pharmaceutical use has on at least one part of its surface a diffractive microstructure which generates diffraction effects which can be perceived in the visible spectral range and which serve as visual safety feature. The tablet includes a plurality of individual powder particles, where the diffractive microstructures are impressed into the surface of the individual powder particles. A compression tool to produce such tablets has on one pressing surface of the compression tool micro-structures, where the microstructures have dimensions which are smaller than the dimensions of the individual crystallites of the material of the pressing surface of the compression tool. The micro-structures of the compression tool can be produced for example by ion etching or by imprinting.

A solid pharmaceutical dosage form [19] has micro- or nanostructures [10a, 10b, 10c, 10d] impressed on the surface thereof or an interface thereof. The dosage form [19] includes a suitable quantity and distribution of ingredients, such as one or more dyes, so as to enhance the optical contrast effect, C, caused by the micro- or nanostructures so that the micro- or nanostructures are observable by the human eye and thereby able to provide anti-counterfeiting characteristics to the dosage form.
