Vagner Ribeiro: Saving energy and optimizing yield in metal casting using gravity and speed-controlled centrifugal feed system. Gravcentri, Harness Dickey & Pierce, May 29, 2012: US08186417 (2 worldwide citation)

Molten metal is introduced into the cavity by a combined gravity feed and centrifugal force feed using a rotating turntable under electrical or electronic control. The centrifugal force is controlled to be substantially constant until the metal has solidified. This is accomplished by controlling the ...
