    摘要: A honeycomb body includes leading and trailing end surfaces being mutually spaced apart in a given flow direction. Subsections are disposed in succession in the given flow direction between the end surfaces. At least some sheet-metal layers have structures forming channels therebetween extending approximately in the given flow direction through which a fluid can flow. The channels have dimensions determined by the structures of the sheet-metal layers. Each of the subsections has a different number of channels per unit of cross-sectional area and the channels have cross-sectional areas differing in each of the subsections. The sheet-metal layers include some layers being smooth or slightly structured in proportion to the dimensions of the channels, having spacings therebetween and extending from the leading to the trailing end surfaces giving the honeycomb body a monolithic form, and the sheet-metal layers include different numbers of other sheet-metal layers filling the spacings in each of the subsections.

    摘要: A process for allowing the attachment of drive or coupling elements, such as cams, gears, crank webs or bearing elements, such as friction bearing bushes, or complete roller bearings on tubes or tubular portions by hydraulic expansion, for the purpose of producing assembled cam shafts, transmission shafts, crank shafts or the like, with the expansion of the tubes taking place exclusively in the region of the respective elements beyond the limit of elasticity of the tubes, against a permanent elastic prestress in the elements. To relieve the load on the seals limiting the regions to be expanded, a counter pressure which is higher than the ambient pressure is applied to the intermediate or end regions.

    摘要: A honeycomb body, especially a catalyst carrier body with a preferably round, oval or elliptical cross section, includes a jacket tube and a stack of at least partly structured sheet-metal layers being intertwined in different directions in the jacket tube. The stack has a given length dimension and a given width dimension. At least one of the sheet-metal layers has a greater thickness over at least part of at least one of the given dimensions than others of the layers. The at least one sheet-metal layer having a greater thickness is formed of thicker sheet metal than the others of the layers or it is formed of a plurality of identically structured metal sheets resting closely against one another.

    摘要: A U-tube heat exchanger for the heat transfer from a primary gas circuit to a secondary gas circuit in a high temperature reactor. At the high temperatures of approximately 950.degree. C., the additionally permissible stresses on the used materials are low. The cold gas collector is therefore flexibly attached at the housing. The arrangement permits complete and also remote-controlled testing from the secondary gas-side of all parts of the primary gas circuit which are stressed by pressure. The flexible elements are neither stressed by the weight of the heat exchanger nor endangered by high temperatures.

    摘要: A catalyzer, in particular for internal combustion engines, has a different that widens in the direction of flow upstream of a honeycombed catalyst body (23), a converger (25) that narrows in the direction of flow downstream of the catalyst body (23) and at least one flow guiding body locating within the diffusor and/or converger. In order to achieve a uniform inflow at the front side of the catalyst body (23) without excessively throttling the flow exhaust gases, a flow guiding body (24) composed of a plurality of adjacent and/or imbricated channels having at least partially an increasing cross-section in the direction of flow is arranged at least in the diffusor. The individual channels preferably have an opening angle that prevents burbling at the walls of the individual channels. In addition, the flow guiding body can be coated with a catalytically active material, thus allowing the volume of the diffusor, if necessary of the converger as well, to be also used for housing catalytically active surfaces. This can improve in particular, besides the inflow at the main catalyst body (23), the cold start properties of the catalyzer.

    摘要: For weight saving purposes and to make optimum use of the material there is provided a hollow shaft, to which drive elements such cams or end flanges are attached preferably by expanding the shaft in portions, made up of at least two layers including an outer layer, preferably produced of a material of a higher strength such as steel and an inner layer produced of a material of a lower strength, such as aluminum or titanium. If there are problems in achieving sufficiently secure fixing of the drive elements by expanding the hollow shaft in the regions to be expanded, it is possible to provide supporting rings which are deformed only plastically whereas the materials of the hollow shaft, as well as the drive elements themselves are deformed only elastically. The regions to be expanded are limited by seals on a pressure probe which is supplied with a pressurized fluid via a channel.
