摘要： A support bar for adjustably mounting accessories such a theatrical lamps wherein the bar is preferably formed of extruded aluminum and the bar is hollow with a closed interior electrical raceway for electrical cables extending the length of the bar and is isolated from a quadrilateral opening extending the length of the bar that communicates with the quadrilateral opening and the exterior of the bar. Adjustable mounting means extend from the lamps into the quadrilateral opening to mount the accessory and to allow sliding movement thereof within the bar.

摘要： An apparatus for the collection of volatiles includes a housing that forms an environmental chamber. Dishs of test sample are placed in this chamber which is closed with a transparent cover. A gasket assures an airtight seal between the cover and the housing. The housing is supported on a stand that allows the angular orientation of the housing to be adjusted relative to the path of the sun. A jacket is also formed in the housing about the environmental chamber. A heat exchange fluid is circulated through this jacket to maintain the environmental chamber and, thus, the test sample within a desired temperature range. Volatiles emitted by the test sample are collected by circulating air through the environmental chamber. This air which passes across the test sample dishes serves to sweep up the volatiles which are then delivered to a collection trap for qualitative and quantitative analysis. The collection trap is formed from one or more modules including a vessel or tube that is closed by a vapor collection adapter. An O-ring seal between the tube and vapor collection adapter ensures an airtight seal. The vapor collection adapter is also provided with cooperating ball and socket connectors on an outlet and inlet respectively that allow for connection of two or more modules in series as desired.
摘要翻译： 用于收集挥发物的装置包括形成环境室的壳体。 将样品盘放置在用透明盖封闭的室中。 垫圈确保盖和壳体之间的气密密封。 壳体支撑在支架上，允许相对于太阳的路径调节壳体的角度定向。 外壳也围绕环境室形成在外壳上。 热交换流体通过该夹套循环，以保持环境室，并因此将测试样品保持在所需温度范围内。 通过循环空气通过环境室收集测试样品发射的挥发物。 穿过测试样品盘的空气用于扫除挥发物，然后将其输送到收集阱以进行定性和定量分析。 收集阱由一个或多个模块形成，包括由蒸气收集适配器关闭的容器或管。 管和蒸气收集适配器之间的O形圈密封确保密封。 蒸汽收集适配器还分别在出口和入口上设置有协作的球和插座连接器，其允许根据需要串联连接两个或更多个模块。
