Prior art main mirrors of this type have a poor capacity for transmitting ponint images and for modulation and are unsuitable for use in the infrared region, because the positioning and adjustment elements, in particular the measurement sensors arranged in the region of the separating lignes between the individual polygonal reflecting elements (1 to 11) emit interfering thermal radiation. Furthermore, the polygonal reflecting elements (1 to 11) of prior art main mirrors (20) are expensive to manufacture.

Abstract: Improved conductors and superconducting magnets are described utilizing superconducting materials exhibiting critical field anisotropy. This anisotropy is one in which the ability of the superconductor to stay in a superconducting state depends on the orientation of a magnetic field applied to the superconductor with respect to the direction of current flow in the superconductor. This anisotropy is utilized in the design of conductors and magnet windings comprising the superconductive material and specifically is directed to magnetic windings (14) in which the direction of high critical current through the superconductor is parallel to the magnetic field (H) produced by current in these windings (14) in order to obtain high critical fields. Particularly favorable examples of a superconducting material are the so-called high - Tc superconductors in which the primary supercurrent flow is confined to two-dimensional Cu-O planes. By arranging the superconductive windings (14) so that the Cu-O planes are substantially parallel to the magnetic field produced by current in these windings (14), the windings (14) will be able to withstand high fields without being driven normal. This maximizes the magnetic field amplitudes that can be produced by the magnet.

Abstract: An absorbent pad such as an incontinence pad comprises a liquid-impervious back sheet with spaced islands of absorbent material thereon. A liquid-pervious cover sheet has pockets formed therein, in which the islands of absorbent material are disposed. The cover sheet is secured, either adhesively or by heat sealing, directly to the impervious sheet along lines that separate the islands of absorbent material and the pockets that contain them. The pad is formed by applying a strip of cover sheet material to a rotating multi-perforate drum and forming the pockets in the cover sheet material either mechanically, or by drawing hot air inwardly through the holes in the drum in the case of a heat-deformable material such as polypropylene fibers. The drum then rotates past a pocket-filling station, where absorbent material such as cellulose fluff is drawn into the pockets by vacuum applied internally of the drum. The cover sheet is then applied to the composite of cover sheet and absorbent material, and is firmly bonded to lines of cover sheet material that are free from absorbent material between the pockets, overlying the bridges that separate the holes through the drum. The composite is then removed from the drum and cut to size.
