摘要： Described is a mixing bin for mixing bulk goods, particularly by pure gravity flow, comprising a mixing pipe disposed at a substantially central location in an outer container and provided with a plurality of intake ports disposed at different levels for withdrawing bulk goods at different levels from a bulk goods column enclosed by the outer container. All intake ports open into a common interior space of the mixing pipe. A respective deflector baffle projecting into the interior space so as to obturate a part of the cross-sectional area thereof is disposed above each intake port to be passed by the bulk goods flow in the interior space. For improving the result of the mixing operation in a structurally simple manner the invention proposes to vary the size of the part of the cross-sectional area obturated by the deflector baffles disposed at the different levels, the selected size of the obturated part of the cross-sectional area being determined by the amount of the bulk goods to be withdrawn through the associated intake port.

摘要： A process and a device for metal spinning a blank into a formed part, especially into a vessel bottom, are described, which can be used for forming materials including materials which are difficult to deform, with high dimensional accuracy and/or high degrees of deformation. For attaining this object, the blank is clamped on its circumference and forced freely, i.e. without using a spinning chuck, into a clearance by means of a motion-controlled spinning tool until its finished dimension is reached.

摘要： A method and an apparatus for cold-forming a sheet blank (2') made of a material with an exponential stress-strain behavior to become a thin-walled, hollow shell (2). The sheet blank (2') is clamped in a clamping means (3) with its circumference and rotatingly rotated around its center line (6). The shaping takes place by a first and a second path-controlled press roll (16, 17) engaging at opposite sides of the sheet blank (2') only by local pressure forces, wherein the relative speed between the workpiece (2', 2) and the press rolls and the force exerted by the press rolls to the workpiece are modulated in a manner that the tensile forces applied to the workpiece are below the yield point of the material.
摘要翻译：一种用于冷成型由具有指数应力 - 应变特性的材料制成的板坯（2'）的方法和装置，以成为薄壁的中空壳体（2）。片材坯料（2'）被夹紧在其周边的夹紧装置（3）中并围绕其中心线（6）旋转旋转。第一和第二路径控制的压榨辊（16,17）仅通过局部压力作用而啮合在板坯（2'）的相对侧上进行成型，其中工件（2'，2）），并且压辊和由压辊施加到工件的力被调制成使得施加到工件的拉伸力低于材料的屈服点。

摘要： An electromagnetically shielded cabin is disclosed which utilizes a novel sealing system enabling reduced maintenance expenditures for maintaining necessary electrical contract, and thus the necessary shield attenuation values, when cabin parts are made of aluminum. The contact surfaces forming part of the novel sealing system are coated with tin which enable the reduced maintenance expenditures and achieve excellent shield attenuation values.
