    摘要： Improved double-stage air filter of modular construction for attachment been aligned openings of a spaced double wall structure in order to supply filtered air flow to a controlled area. The filter is generally made up of casing means and combined plate and sleeve means. Both the casing means and plate means are provided with a flange means. The sleeve means is provided with a series of perforations and the plate means flange means is provided with a plurality of relatively spaced slots. The casing means flange means is affixed to the outer wall so that the casing means extends between the walls. The plate means includes retainer means that is affixed to the inner wall so that the sleeve means is inserted in the casing means. Inner and outer filter means for cleaning and purifying an air flow are disposed about the sleeve means. Retainer means are connected to the casing means flange means so as to hold the filter means in sealing engagement between the last mentioned retainer means and the plate means. During use of the filter, an airflow to be filtered is directed through the sleeve perforations, the filter means, and the slots of the plate means flange means thereby supplying filtered air to the controlled area. Depending on the filtered air flow requirements of a controlled area, one or more filters of the invention can be arranged in any suitable arrayed configuration in relation to the walled structure. Whenever a filter needs to be serviced the plate means retainer means is temporarily covered thereby preventing the entrance of unfiltered air to the controlled area. One of the advantages of the double-stage air filter is that it not only removes particles from an air flow, but also purifies same from the toxic effects of chemical, biological, radiological agents, or any combination thereof.

    摘要翻译： 改进的双级空气过滤器的模块化结构，用于连接在间隔开的双壁结构的对齐的开口之间，以便将过滤的空气流供应到受控区域。 过滤器通常由套管装置和组合板和套筒装置组成。 壳体装置和板装置均设有凸缘装置。 套筒装置设置有一系列穿孔，并且板装置法兰装置设置有多个相对间隔开的槽。 套管意味着法兰装置固定到外壁上，使得套管装置在壁之间延伸。 板装置包括固定在内壁上的固定装置，使得套筒装置插入壳体装置中。 用于清洁和净化空气流的内部和外部过滤器装置设置在套筒装置周围。 保持器装置连接到套管装置法兰装置，以便将过滤装置保持在最后提到的保持装置和板装置之间的密封接合中。 在使用过滤器期间，要过滤的气流被引导穿过套筒穿孔，过滤装置，并且板的槽意味着法兰装置，从而将过滤的空气供应到受控区域。 根据受控区域的过滤空气流量要求，本发明的一个或多个过滤器可以相对于有围壁的结构以任何合适的排列构造布置。 每当过滤器需要维修时，板件意味着保持器装置被暂时覆盖，从而防止未过滤的空气进入受控区域。 双级空气过滤器的优点之一是它不仅从空气流中除去颗粒，而且还从化学，生物，放射性物质或其任何组合的毒性效应中净化。

    摘要： The tail section of a fin-stabilized, guided projectile having centrifuga deployed fins is disclosed. A fin retainer and release mechanism engages the projectile fins and holds the fins within the projectile diameter during normal stowage, handling and travel of the projectile down the gun tube. The fin retainer and release mechanism is designed to operate from the forces of gun launch to enable centrifugal deployment of the fins due to projectile rotation after the projectile leaves the gun tube.
