Abstract: A method of producing a printing plate on a cylindrical printing-plate carrier includes subdividing the printing-plate carrier by computation in terms of its width and axial length into at least two circumferential subareas. Then an actual transfer characteristic curve for each subarea is determined and compared by computation with a predetermined desired printing characteristic curve for each subarea to find a deviation. The method further includes calculating a correction to compensate for each deviation; receiving a digital image data in a first data format using a raster image processor; converting the digital image data into machine-specific image data including the position and the tonal value in the form of a bitmap; applying the correction for a predetermined desired printing characteristic curve for the edition print to the machine-specific image data using the raster image processor; and supplying the corrected machine-specific image data to an imagesetting unit.

Abstract: The present invention relates to a method and apparatus for the formation of three-dimensional features in fabric. The fabric may be fed into a set of pin chains or rollers, wherein the fabric may be vertically disposed. The pin chains or rollers may contain feature forming pins that when applied to the fabric form three-dimensional features in the fabric surface. The feature forming pins may be removable and arranged to form a variety of patterns and images.

Abstract: In a method of charging fine-grained metals, in particular directly reduced iron (DRI), into an electric-arc furnace (1), the metal is supplied via a downpipe (12) to an opening (10) provided in the furnace roof (4), is introduced into the furnace (1) through this opening (10) as bulk material stream (11), and falls onto the melt (13) merely by gravity. Further, an electric-arc furnace (1) suited for this purpose is described. A rather loss-free introduction even of fine-grained material having a mean grain size of less than 1 mm is achieved by passing the bulk material stream (11) through a dosing orifice (8) after the downpipe (12) and before entering the furnace (1). The bulk material stream (11) then enters the furnace essentially undisturbed.

Abstract: A floatable smoke pot which floats in a stable position with a casing can water-tightly closed by a cover through a closure device. Smoke-generating bodies of a pyrotechnic material, which can be ignited by an igniting device, are arranged in the casing can. A stable floating position is achieve through a ballast weight in the casing can at the can bottom (14). A number of column elements forming the smoke-generating bodies are arranged in the casing can in a uniformly distributed relationship, standing on the ballast weight. The space which remains free of the column elements in the casing can is filled with a buoyancy material. The cover has holes which in the unused original condition of the smoke pot are water-tightly closed with closure elements which can be torn open so that the smoke pot can also be submerged in water for a limited time without extinguishing of the smoke-generating bodies.
