Abstract: A multiple serving container shaped to incorporate an opening dimensionally sized to fit within the opening of the typical plastic liquid containers used for bottling water, fruit juice and soda. The serving container fitting inside an opening into the liquid container allows transfer of contents without spillage.

Abstract: A modular panel, which in use is laid in a continuous two-dimensional array over a supporting sub-surface to form a hollow floor, wall or ceiling suitable for reticulating electrical, optic-fibre, hydraulic and other conduit. The panel having upper and lower duct zones each partitioned by lateral ribs and longitudinal ribs respectively. The upper duct zone being in communication with the lower duct zone by way of vertical duct sets.

Abstract: Radiant energy reflecting structures are described which are elongate and which have a plurality of reflecting elements on or in their surface. Each reflecting element has a "major axis" of reflection (the term "major axis" is defined in this specification), and a feature of the reflecting structures is that the direction of the "major axis" varies progressively with the transverse position of a reflecting element on the structure. The reflecting surfaces of the reflecting elements may be formed as corrugated, elongate, planar reflectors. Alternatively they may be formed as a known form of retro-reflective surface construction. Preferably, the reflecting surfaces are overlaid with a transparent medium. The structures may be used to construct louvred radiant energy screens.

Abstract: Radiant energy screens are constructed as louvred screens, with the louvre elements each having second-surface retro-reflective elements on or in their outwardly facing surfaces. The inwardly facing surfaces of the louvre elements may be highly reflective to reduce their emissivity. The reflecting surfaces of the retro-reflective elements may be, inter alia, inclined elongate reflectors, cube-corner reflectors, or lens and mirror combinations.
