Abstract: A foundry flask includes at least three discrete corner sections and at least three discrete side sections wherein the yield strength of the corner sections is greater than the yield strength of the side sections. Each one of the corner sections is connected to a pair of the side sections so as to form a foundry flask section that has at least three sides. The foundry flask further includes a bottom member that is connected to the foundry flask section.

Abstract: A bulk hopper tank assembly which has a bulk hopper tank containing an opening at the top end thereof wherein a lid assembly selectively covers the opening. The lid assembly includes a lid, a generally vertical arm extending along the exterior side of the bulk hopper tank, and a generally horizontal arm connecting the lid and the vertical arm. A lifter connects to the vertical arm and is moveable between a down position in which the lid covers the opening in the bulk hopper tank and an up position in which the lid is vertically above the opening in the bulk hopper tank. A handle connects to the vertical arm and is moveable to a plurality of positions between a first position in which the lid is in the vertical volume of the opening and a second position in which the lid is outside of the vertical volume of the opening.
