Abstract: A sealing member for a louvre mounting assembly is described. The louvre mounting assembly is of the type to allow co-rotation of at least first and second louvre panes between open and closed positions. The sealing member located in an end clip for the first louvre pane of the louvre mounting assembly, wherein the sealing member includes a first sealing region for sealing against a portion of the second louvre pane to seal against movement of liquid into the end clip when the louvre mounting assembly is in a closed position.

Abstract: A retention assembly for securing an edge portion of a screen to a surround arrangement is disclosed where the surround arrangement includes a receiving channel to receive the edge portion of the screen and the receiving channel is formed by first and second opposed wall portions.

Abstract: A support trolley comprises a central leg pillar and at least three legs radiating therefrom, each supported at its outer end by a respective castor wheel assembly. The inner end of each leg joins the lower end of the leg pillar by a sliding engagement of complementary splined surfaces, so that assembly or disassembly is easily effected. The outer end of each leg has a downwardly facing recess which receives the upwardly directed pintle of a respective castor wheel assembly, that pintle being tubular and of resilient material.

Abstract: Evaporative coolers, in the past, have used blowers or fans with horizontal axes of rotation, and pumps with vertical axes of rotation, since the pumps were immersed in base tanks and were thereby always primed. Consequently there has been a need for two separate motors, or alternatively, for drive means between the fan motor and the pump drive shaft. This invention relates to a water distribution means which primes a pump, even though it is above the base tank, by providing a suction conduit with an upwardly directed elbow between the pump and the base tank which will drain when the pump stops, but the spreader above the pump contains a well which slowly empties into the pump housing and conduit, the elbow inhibiting any further syphoning of the water from the pump housing into the base tank. Accordingly, the pump may be coupled to the fan for coaxial rotation therewith.
