摘要： A structural strut having at least one surface of generally U-shaped cross section and being formed with a pair of upstanding side walls having opposed tapers. The side wall tapers of the strut shift or skew the neutral axis of the member in proportion to the relative side wall dimensions. In this manner, the strut may be used to comprise a load bearing member having a neutral axis selectively slanted to a position maximizing structural loading efficiency and interconnection. The ends of the strut are further formed of substantially planar construction for flat abutment and welded attachment to cross members of a truss thereby eliminating conventional gusset plates. The structural strut may also be constructed from a pair of such U-shaped channel sections secured back-to-back with the tapering flanges complementally positioned opposite one another for selectively shifting the neutral axis of the resulting I-beam. In this manner, the strut beams of the invention present their respective neutral axes in the most advantageous configuration for maximum structural integrity and efficient interconnection.

摘要： A distribution duct for a reactor which can be easily fabricated. The duct has an elongated back plate and an elongated perforated front plate made up of flat segments separated by elongated angular breaks, and two flat marginal edge portions on the opposite sides thereof, the marginal edge portions being in flush engagement with, and secured to the back plate adjacent to the sides thereof, the flat segments defining with the back plate a flow chamber.

摘要： The device of the present invention utilizes a unitized scheme to erect a sulphur dioxide scrubber tower wherein a set of factory built constituent subunits are joined at location to produce a single functional unit. The functional units themselves preferably are adaptable for parallel grouping as necessary to insure the treatment capacity required for the emission rate of any given application or where otherwise appropriate for other process reasons.The temporary strength and rigidity necessary to maintain a subunit's critical geometric integrity throughout construction, transportation and erection processes is provided by a reusable exoskeletal support cradle. Preferably each subunit is initially constructed upon such a cradle. Alternatively, subunits are constructed in jigs at the factory and transferred to the support cradles before shipping to the construction site. Each subunit is transported to location, rotated for erection, lifted into place and attached into assembly while still affixed to its cradle. Thereafter the cradle, having served its purpose, is removed and returned to the factory for reuse. The assembled functional unit has a minimal amount of internal members and relies upon cooperation between subunits to support the tower.
摘要翻译： 本发明的装置利用一体化方案来竖立一个二氧化硫洗涤器塔，其中一组工厂构建的组成子单元在位置连接以产生单个功能单元。 功能单元本身优选适于根据需要并行分组，以确保任何给定应用的排放速率所需的处理能力，或者其他适用于其它处理原因的情况。 在建筑，运输和架设过程中保持亚单位关键几何完整性所需的临时强度和刚度由可重复使用的外骨骼支架提供。 优选地，每个子单元最初构造在这样的支架上。 或者，子单元在出厂时在夹具中构建，并在运送到施工现场之前转移到支撑架上。 每个子单元被运送到位置，旋转以安装，提升到位并附接到组件中，同时仍然固定在其支架上。 此后，已经服务于其目的的摇篮被移除并返回工厂进行再利用。 组装的功能单元具有最小量的内部构件，并且依赖于子单元之间的协作来支撑塔架。

摘要： Novel quick opening removable tray sections or deck plates for trays of fluid contact vessels having foldable closures or covers adapted to rest upon frame members which coact to form perimeters of one or more polygonal, preferably quadrangular, complementary openings in each tray. Each cover has at least a pair of closure panels hingedly connected at their adjacent inner margins. Opposed outer lateral or side margins of closure panels, which overlie complementary lateral or side frame members in spaced relationship, extend in the same general direction as their adjacent inner margins. At least one of opposed outer lateral margins is slidably confined whereby cover is removable upon elevating closure panels at their hinged inner margins and simultaneously sliding said outer lateral panel margins toward each other and out of confinement so as to permit folding of said cover. If desired, one of opposed outer lateral margins of closure panels may be hingedly connected to adjacent edge portion of tray instead of being slidably confined. Frictional fasteners detachably secure end margins of closure panels adjacent their hinged connection to underlying portions of end frame members at opposed ends of tray opening. Any of the deck plates of a tray may be removably mounted in this manner.
摘要翻译： 新颖的快速打开可移动托盘部分或用于流体接触容器托盘的甲板，其具有适于搁置在框架构件上的可折叠闭合件或盖，其共同形成在每个托盘中的一个或多个多边形，优选四边形互补开口的周边。 每个盖具有至少一对在其相邻的内边缘处铰接连接的封闭面板。 封闭面板的相对的外侧或侧边缘以相互间隔的关系覆盖互补的侧框架构件或侧框架构件，其延伸方向与其相邻的内边缘相同。 相对的外侧边缘中的至少一个被可滑动地限制，由此当在其铰接的内边缘处提升封闭面板时可以移除盖，并且同时将所述外侧边缘边缘朝向彼此滑动并且不受限制，以允许所述盖的折叠。 如果需要，闭合面板的相对的外侧边缘之一可以铰接地连接到托盘的相邻边缘部分，而不是可滑动地限制。 摩擦紧固件将封闭板的端部边缘可拆卸地固定在它们的铰接连接件的端部框架构件的下部，在托盘开口的相对端处。 托盘的任何甲板可以以这种方式可拆卸地安装。
