A submerged intake filter assembly comprising a cylindrical screen, a first end plate, a second end plate, a primary flow modifier pipe, and a plurality of secondary flow modifier pipes. The primary flow modifier pipe is eccentric with the cylindrical screen at the first end plate. The secondary flow modifier pipes are positioned to lie in an annular space between the primary flow modifier pipe and the cylindrical screen.

The apparatus of claim 12 wherein the at least one additional feed chute comprises a pair of additional feed chutes to respectively provide metal chips to both of the molds, each of the additional feed chutes including an adjustable chute moveable to a plurality of positions over the respective mold for improved mixing of the metal chips in the respective mold melting cavity. 14. The apparatus of claim 13 wherein each of the feed chutes is moveable laterally side to side. 15. The apparatus of claim 14 wherein the lateral side to side movement extends respectively over substantially all of the main hearth or molds. 16. The apparatus of claim 15 wherein each of the feed chutes is a vibratory feed chute. 17. The apparatus of claim 12 further including first and second refining hearths each defining a melting cavity, the first refining hearth positioned in between the main hearth and the first mold and the second refining hearth positioned in between the main hearth and the second mold. 18. The apparatus of claim 17 further comprising an additional pair of additional feed chutes respectively to provide metal chips to both of the refining hearths, each of the refining hearth additional feed chutes including an adjustable chute moveable to a plurality of positions over the respectively refining hearths for improved mixing of the metal chips in the respective refining hearth melting cavity. sonance Imagining: Diagnostic and Interventional Applications, Pediatric Cardiology vol. 21, 2000, at 80-98.
