Abstract: A valved cover device prevents pump cavitation of a swimming pool pump by allowing air to be released through an open valve of a strainer cover. The device includes a strainer cover configured for positioning over a strainer housing for a swimming pool pump. An air-bleed valve extends into the strainer cover. The air-bleed valve is selectively manipulated wherein the air bleed valve is configured to vent an interior of the housing when the strainer cover is positioned over and closes an access opening into the interior of the housing. The air-bleed valve is configured for environmentally communicating with the interior of the housing wherein a gas is permitted to bleed outwardly through the strainer cover when the strainer cover closes the access opening and the air-bleed valve is actuated.

Abstract: An article moving attachment, and the like, including a grapple member adapted for engaging, for example, base runners of skids or pallets, or other articles, and being selectively connectable to power actuated means such as a line, through which a skid or an article can be moved from an initial position of perhaps difficult access to a subsequent position providing ready access to facilitate removal from a carrier, or unloading by a lift fork truck, and the like. The attachment includes mechanism coactable with the grapple member whereby a grappling force is directly proportional to the weight of an article being moved.
