    • A pipe filter and closure assembly comprises a support member in the form of an annular collar or sleeve. In use the collar is positioned wholly within the pipe at some distance from an open (upper) end of the pipe. A filter element in the form of a strainer is releasably mountable to the collar so as to inhibit the passage of solid material through the pipe, whilst allowing the passage of fluids (liquids and gases) therethrough. A closure member in the form of a plug in use is mountable inside the collar to be seated at the strainer. In use when the plug is in place, the flow of material through the pipe is blocked. The location of the assembly or part thereof arrangeable wholly within the pipe reduces the ease of access to and presents significant difficulties for an operator seeking to tamper with the assembly.
    • 管道过滤器和封闭组件包括环形套环或套筒形式的支撑构件。 在使用中,套管完全位于管道内,距离管道的开放(上)端有一定距离。 过滤器形式的过滤元件可释放地安装到套环上,以便阻止固体材料通过管道,同时允许流体(液体和气体)通过其中。 使用插头形式的封闭构件可安装在套环内,以便安置在过滤器上。 在使用插头就位时,通过管道的材料流被堵塞。 组件或其整体在管内布置的部分的位置减少了访问的容易性,并且对于寻求篡改组件的操作者而言显示出显着的困难。

    • A performance shell (1) for outdoor music performance including a platform (2) providing a performance area for receiving at least one sound source, the platform combining unitarily with a rear wall reflectors (5), side wall reflector (6) and a canopy reflector (7) to define an enclosure having a front opening (11) for communicating acoustically with an open air audience area. The canopy reflector includes a main portion (8) extending above the performance area and a projecting portion (9) projecting forwardly of a front edge of the performance area, the canopy reflector further including sound diffusion formations (13) on an underside of the main portion and the projecting portion and adapted to provide non-specular reflection of sound from the at least one sound source for enhancing sound received both in the performance area and the audience area.
