Abstract: An idler roller (4, 5, 6) for supporting an endless belt (2) in a roller conveyor (1) that includes a frame (7) for mounting the idler roller (4, 5, 6) to the conveyor (1), a support shaft (8) mountable to the frame (7) for supporting the idler roller (4, 5, 6) and a roller casing (9) rotatably mountable to the shaft (8) by a bearing assembly (10). The bearing assembly is substantially enclosed within the roller casing. The idler roller (4, 5, 6) is cantilevered to the conveyor (1) such that the bending moment of a load exerted on the roller casing (9) is displaced onto the bearing assembly (10).

Abstract: The present invention provides an idler roller (4, 5, 6) for supporting an endless belt (2) in a roller conveyor (1), said idler roller (4, 5, 6) including a frame (7) for mounting the idler roller (4, 5, 6) to the conveyor (1); a support shaft (8) mountable to the frame (7) for supporting the idler roller (4, 5, 6); and a roller casing (9) rotatably mountable to the shaft (8) by a bearing assembly (10), the bearing assembly being substantially enclosed within the roller casing, wherein the idler roller (4, 5, 6) is cantilevered to the conveyor (1) such that the bending moment of a load exerted on the roller casing (9) is displaced onto the bearing assembly (10). A roller conveyor (1) is also provided, which includes an endless belt (2) for transporting a bulk material (3) and a plurality of idler rollers for supporting the endless belt (2), wherein one or more of the idler rollers (4, 5, 6) are in accordance with the invention.

Abstract: The present invention relates generally to a fluid level control system comprising a level sensor (10), and a valve in the form of a shut-off valve (12). The level sensor (10) is mounted to a vessel (not shown) and designed to sense the level of fluid, such as fuel, in the vessel. The shut-off valve (12) is designed to be actuated by a dry-break refuelling nozzle (not illustrated). The shut-off valve (12) is operatively coupled to the level sensor (10) via a sampling flow line (14) together with first and second hydraulic return lines (16) and (18), respectively. The shut-off valve (12) is of a normally-open configuration wherein it permits the flow of fuel from the refuelling nozzle to the vessel whilst the fluid or fuel level is below a predetermined level. The level sensor (10) is configured to effect closure of the shut-off valve (12) when the fuel level is at the predetermined level.
