Title: Preparation of catalysts for NOx reduction, preferably downstream of fossil-fuel power stations, by ceramicising the composition with the exclusion of air
Inventor: HOELTER HEINZ DIPL ING
IPC: B01J37/08
Filed: 1985-06-29
Abstract: The invention relates to a process for the preparation of catalysts for NOx reduction, preferably downstream of fossil-fuel power stations. The main application P 3440808.8 proposes that the catalyst support compositions from flotation tailings, which have an inherently high "C" proportion, be additionally enriched with coal, sawdust or other organic materials and to carry out ceramication only to such a degree that part of the carbon present is preserved in the ceramication material as a partly carbonised composition. Surprisingly it was found that the mixed support compositions, which have been ceramicised with the exclusion of air, have a higher reactivity and that the predominant fraction of carbon is retained in the catalyst composition if ceramication is carried out with the exclusion of air. This ensures that the conversion of NOx via this catalyst composition can be carried out without ammonia or another additive to give free nitrogen, carbon dioxide and water.

Title: High-voltage-resistant optocoupler
Inventor: KARNBACH PETER DIPL PHYS
IPC: H04B10/80
Filed: 1985-07-20
Abstract: The object of the invention consists in the creation of an economical manufacturing technology and this object has been achieved in such a way that the discretely encapsulated transmitter and receiver components are located opposite one another in a radially spring-loaded sleeve made of glass, plastic, ceramics or preferably metal, the latter having the shape of a wound spiral spring with no space between the coils with its ends overlapping. The inside of the sleeve is a reflective metal surface. The disposition of the radially spring-loaded sleeve around the discrete components guarantees a substantial increase in the coupling factor and reduces the overall assembly cost to the insertion of the discrete components into the sleeve and the subsequent enclosure.

Filed: 1985-08-28
Abstract: The invention relates to a flat pallet having compartments for receiving indexable inserts (T, C, S, R) of different basic geometrical shape having the same incircle diameter (I) with the same position of their incentres (M) and a particular orientation in the compartments. The compartments comprise bearing elements (12), which are designed as pins (19a, 19b, 19c, 19d, 19e, 19f). The pins rise up from the bottom of the flat pallet and, seen in plan view of the flat pallet, are located in the region of those intersections (14, 15, 16, 17, 18) of the side faces of the indexable inserts (T, C, S, R) which lie in the vicinity of the common incircle (I) of the indexable inserts. Indexable inserts of triangular, square, rhomboidal and round shape can be inserted into the compartments formed by the pins. This makes it possible to arrange respectively in a compartment of the flat pallet indexable inserts of different basic geometrical shapes with a particular spatial arrangement. Indexable inserts stored in this way can be fed to an automatic handling operation. Furthermore, only one type of flat pallet is required in order to store indexable inserts of different basic geometrical shapes in a particular spatial arrangement. <IMAGE>

Patent DE-3719957-A1 (DE)
Inventor: TANAKA ISAO
IPC: D06Q1/00
Filed: 1987-06-15
Abstract: An exothermic-sensitive-substance such as graphite and carbon black is placed in the interior or on the surface or near the surface of a synthetic fiber or high molecular substance which is forming a fabric or sheet, such as a seat top layer, seat covering, wall covering, carpet, curtain or clothing. Subsequently the synthetic fiber or high molecular substance is near infrared irradiated until the exothermic-sensitive- substance grows hotter and generates heat, thereby heating up the synthetic fiber or high molecular substance to soften, shrink, melt, weld, or melt-break it. Thus, the fabric or sheet is heated indirectly and the part of the fabric or sheet, in which the exothermic-sensitive-substance does not occur, is not heated and thus neither shrinks nor melts. By this partial shrinking, melting or melt-breaking, it becomes possible to draw crimping-patterns, embossing-patterns and see-through-patterns or very thin fabrics and sheets.
