Abstract: A forming tool and a method of operating thereof for producing a hollow component by sheet-metal forming is disclosed having an upper tool and a lower tool, a mandrel that is driven into the hollow component to be formed and an auxiliary mandrel that is repositionable relative to the mandrel are positioned on the upper tool. The mandrel and the auxiliary mandrel are coupled to the upper tool by one spring-elastic actuation element in such a manner that the mandrel, when the upper tool is being lowered, is driven into the hollow component to be formed and comes to bear therein. A further lowering of the upper tool causes a compression of the coupling element, and the auxiliary mandrel carrying out a movement relative to the mandrel and being driven further into the hollow component.

Abstract: A method for processing value documents includes employing a storage device for data which has a storage area of pre-specified storage-area size, wherein value documents are transported in singled form to a sensor device. Respective value document measuring data are captured by means of the sensor device. A storage priority is established for the respective value document as a pre-specified function of at least a portion of the measuring data that is necessary for establishing the storage priority in dependence on the established storage priority processing data for the respective value document stored in a storage block in the storage area. The storage priority influences the duration of the storage of the respective processing data.

Abstract: An apparatus for substrate treatment by means of laser radiation includes a rotating polygonal mirror by which at least one incident laser beam is reflected and is pivotable across an arrangement of converging lenses which lie next to one another and which are arranged at a spacing from the substrate corresponding precisely or approximately to their focal lengths. The rotating polygonal mirror is divided into at least two regions having a different number of facets and is adjustable such that different regions can be introduced into the beam path of the laser radiation and accordingly different sweep angles or fan angles of the laser beam reflected by the rotating polygonal mirror can be set.

Abstract: A method for processing sheet material such as bank notes by collecting measuring data from a plurality of sensor units. From the collected measuring data, deriving measuring results. Then mapping such measuring results on classes, combining individual classes into a property of sheet material with different forms, setting up a freely configurable rule matrix by method of which arbitrary but firmly selected combination of different forms of a quantity of properties can be associated with a sort class, deriving the sort class of the sheet material using the rule matrix, assigning the sort class to the sheet material, transporting the sheet material to a destination unit with the reference to the sort class of the sheet material.

Abstract: In an apparatus for testing sheet material, at least one sensor unit is provided with a memory in which data records of a plurality of sheets can be managed. Each data record is provided with areas in which data from at least one other sensor unit can be stored. The sensor unit preferably has a measuring unit and an evaluation unit, the memory of the sensor unit being provided in the evaluation unit.

Abstract: Apparatus is disclosed for threading tapping holes in workpieces wherein the tapping hole is surrounded by a surface having alternating recesses and arcuate projections which are to be threaded. The apparatus has a hold-down plate one side of which is movable against the exposed side of the workpiece, a carrier which is reciprocable toward and away from the workpiece by a plunger and a spring, a tool holder which has external threads meshing with the internal threads of a nut in the hold-down plate and a helical cam groove receiving a pin of the carrier, and a fluted tap which is coaxially affixed to the holder and extends into the tapping hole when the hold-down plate abuts against the workpiece whereby the externally threaded ribs of the tap which alternate with the flutes extend into the recesses in the surface surrounding the tapping hole.

Abstract: Spherical refining catalysts containing cobalt and/or nickel together with molybdenum on aluminum oxide are prepared in closed mixers provided with mixing elements from spray-dried powders such as catalyst preparations or carriers using peptizing agents. The catalysts thus prepared have a bulk density much higher than that of extrudates of similar composition. Their surface and pore size distribution make them suitable for use in the catalytic refining of hydrocarbon fractions containing metal and asphalt, and particularly for refining vacuum distillates and residues from atmospheric distillation.
