Abstract: A landfill for the permanent disposal of wastewater sludge. The landfill includes an impoundment having a base that is substantially liquid impervious. Dikes supported by the base surround the perimeter of the base where needed. A liquid collection and conveying system is embedded in a liquid pervious layer which overlies the base; this system operates to dewater wastewater sludge deposited within the impoundment. The impoundment is adapted to be closed after the sludge is dewatered by spreading a liquid impervious layer over the dewatered sludge.

Abstract: A box spring assembly which includes a generally rectangular frame, a plurality of upwardly extending wire springs mounted on the frame, and a wire grid supported on the upper ends of the springs so that the grid and springs cooperate to yieldably resist downwardly directed bedding loads. Each of the springs has a body comprised of two side-by-side arcuate portions formed integral at their upper ends with torsion bars that are connected by a connecting bar located between the arcuate portions. The arcuate body portions thus resist bedding loads with bending stresses and without any areas of stress concentration that would cause early spring failure. The torsion bars in each spring divide the spring load and resist bedding loads principally with torsional stresses, the combination of both bending and torsional stresses in the springs enabling increased load-resisting capabilities in the springs with a resulting efficient use of spring wire material.
