Abstract: The invention provides an aerial lift bucket insert having a raised step. The bucket insert is comprised of a pan, the pan having a raised rim wall that includes a handle and a raised step. The raised step has an area beneath the raised step that is sufficient to accommodate a worker's boot. The bottom of the pan and the top of the step are provided with scuff pads. In other embodiments, there can be a plurality of raised steps one atop the other or in opposing corners. The raised formed step is 9 inches high, has a depth of 5.5 inches and the distance between the bottom of the raised formed step and the pan is 5 inches. A cutout handle in the wall facilitates cleaning of the insert.

Abstract: Scuff pad with step with which resides interiorly of an aerial lift bucket, or bucket liner if provided, at the bottom thereof and which includes a base portion and an upwardly extending portion extending upwardly of the base portion of a predetermined distance, the base portion has a top surface for being engaged by the shoes of said person upon standing in said bucket or liner to prevent scuffing, and the upwardly extending portion has a top surface providing a step which facilitates climbing out of said bucket or liner by the workman.

Abstract: The floatable element or pad including a body of floatable material, such as for example a low density polyethylene, or a high density cross-linked polyethylene, and the like, having a horizontal cross-sectional shape, such as hexagonal, enabling a plurality of such floating elements or pads to engage in flat surface-to-surface contact thereby providing a substantially gapless floating insulating cover. In one embodiment, the floatable element or pad includes top and bottom layers, side walls, and a plurality of thru-posts extending between the top and bottom layers and providing structural rigidity thereto, and wherein the top and bottom layers, side walls and thru-posts cooperatively provided a plurality of dead air spaces providing additional insulation between the liquid, slurry, semi-liquid or the like on which an insulating floatable cover comprised of such floatable elements or pad is comprised.

Abstract: A collar for fitting over the upper end of the cake discharge chute of a rotatable disc filter, or the like. The collar has a plurality of downwardly and inwardly sloping walls which substantially reduce any tendency for cake to stick to the sides of the chute. For use with heavy cake, reinforcing members may be provided for the collar. The collar is configured for use with discharge chutes of diverse design.

Abstract: A disc filter chute liner for being inserted in the passageway formed in a cake discharge chute of a disc filter and for being interposed between the cake discharge chute and cake passing therethrough and for preventing the cake from adhering to the cake discharge filter, the disc filter chute liner being provided with smooth and slick internal surfaces with respect to the cake whereby the cake passing through the liner will not adhere to the smooth and slick surfaces and thereby in turn will not adhere to the cake discharge chute.
