Abstract:
1. A method for rotating a mold comprising: placing the mold in an L-shaped mold rotator having a first section and a second section approximately perpendicular to the first section; rotating the L-shaped mold rotator, along a curved section that joins the first section and the second section of the L-shaped mold rotator, from a first position to a second position; and changing a center of gravity of the L-shaped mold rotator by transferring a fluid, within at least a conduit and during the rotating, between the first section of the L-shaped mold rotator and the second section of the L-shaped mold rotator, wherein a resulting changed center of gravity stabilizes the L-shaped mold rotator in the second position.
