Abstract: An application of omega-3 and/or omega-6 fatty acid(s) for the therapeutic treatment of the human or animal body in the case of an impaired sphingolipid metabolism, in particular in the case of impaired sphingolipid synthesis and/or excessive sphingolipid degradation. The agent is applied in the case of missing, reduced and/or defective formation of a sphingomyelin synthase enzyme in the body, in particular the enzyme sphingomyelin synthase 1 or the enzyme sphingomyelin synthase 2. The application has proved to be useful in the case of a defect of the sphingomyelin synthase 1 gene or of the sphingomyelin synthase 2 gene. The omega-3 and/or omega-6 fatty acid(s) preferably comprise(s) polyunsaturated omega-3 and/or omega-6 fatty acid(s), preferably EPA, DHA, DPA, ETA, 21:5n3 and/or SDA. A method for determining a cause of a disease in an animal or a human being and a device for carrying out the method are also provided.

Abstract: A manufacturing method for a heavy munition casing is provided, in which steel is rolled as a rough sheet or is forged as a slab depending on the desired casing size. Steel plates (2) produced in this way have a thickness that is somewhat greater than the manufacturing diameter of the munition casing (5). The steel used for this purpose has longitudinally oriented manganese sulfides (3), which are also shaped in the lateral direction, in addition to main shaping in the longitudinal direction, by shaping to form the shaped steel plate (2), and assume a longitudinally extending plate-shape as well. The initial material for the casing (5) is taken from an approximately rectangular steel plate (2), transversely with respect to the deformation direction. The quadrilateral piece obtained in this way is then turned to be round and is mechanically processed to form the shape of the casing (5).

Abstract: It is proposed to make a change to the barrel material and also its constituent proportions and to undertake a production method which is already known from the large caliber barrel but which is specially adapted for medium caliber barrels. A barrel is created which is now made from a NiCrMoV steel blank which as an ingot was remelted in the ESR (electro-slag remelting) process before forging and the forged bars were quenched and tempered in a liquid quenching and tempering process. A barrel for a machine gun is thus disclosed which has the quality/characteristics of a large caliber barrel.

Abstract: The method for producing tubes for heavy guns employs a heat-treatable steel, consisting in wt.-% of 0.20 to 0.50% carbon, max. 1.0% silicon, max. 1.0% manganese, max. 0.03% phosphorus, max. 0.03% sulfur, max. 0.1% aluminum, max. 4% nickel, max. 2% chromium, max. 1% molybdenum, max. 0.5% vanadium, and the remainder of iron and the customary impurities. Forgings of open-smelted cast ingots are pre-worked on a lathe on the outside. The solid blanks obtained in this way are hardened and tempered, only subsequently drilled and then finished.

Abstract: The proposed brake disk consists of steel of a composition of 0.1 to 0.4% of carbon, up to 1.0% of silicon, up to 2.0% of manganese, up to 0.02% of sulfur, 11 to 16% of chromium, up to 1.0% of nickel and 0.5 to 1.5% of molybdenum, the remainder being iron and production-related impurities.

Abstract: A pre-hardened and pre-tempered tool steel is used for producing molds for plastic parts, in particular matrices of large dimensions. In order to make possible high core hardness without qualitative disadvantages even at large diameters, a tool steel is proposed, which has a composition in weight-% of C=0.25 to 0.30, SI=0.04 to 0.20, Mn=1.2 to 2.0, Cr=1.0 to 2.0, Ni=0.9 to 1.5, Mo=0.3 to 0.8, V≦0.2 and Al=0.01 to 0.03, wherein the remainder consists of iron and the unavoidable impurities. The addition of boron for increasing hardness was intentionally omitted since it has been shown that with larger diameters boron results in non-reproducible hardness, in particular in the core area.

Abstract: A one-piece or multi-part connecting rod includes a connecting rod eye, connecting rod shaft and a connecting rod head which is manufactured from at least one sheet metal strip. The sheet metal strip is shaped on both sides with essentially perpendicular fins and is bent normal to its main planed formed cylindrical or semi-cylindrical bearing surfaces about the bearing axes of the connecting rod head and connecting rod eye. The sheet metal pieces are fastenable near the bearing surfaces. The sheet metal connecting rods thus produced can be moved in automobile engines.

Abstract: The equipment is intended for exposing both side of printed circuit plates by means of a contact print. The equipment comprises a master copy and printed circuit plates holder in a rack provided with feeding elements and guided in parallel between two light sources and comprising respectively one portion above and below the exposure plane. The holder is formed of a dual frame (1) the two frame portions 2,2' of which are formed to be moved part and together relative to one another and in parallel to one another and while remaining in a position parallel with respect to one another. Located in the frame portions (2,2') of the dual frame (1) is respectively one transparency (4) framed by a frame (5) provided at least on one side thereof with alignment elements (15), with suction ports (7) being provided in its counterdirected surfaces (6) along the circumferential edges thereof.
