Abstract: A forging press includes a die set having a stationary die, a movable die in facing-but-spaced-apart relation to the stationary die along a press axis and defining a workpiece volume therebetween, and an exterior constraint extending circumferentially around the workpiece volume. The movable die has a base level region lying generally in a workpiece plane perpendicular to the press axis, and three rotationally symmetric segments raised above the base level region. Each of the segments forms an angular segment of a disk having an included segment angle and that is angularly separated from the other segments. A press mechanism includes a axial drive operable to move the movable die in a direction parallel to the press axis, and an indexing drive operable to rotate the movable die about the press axis by an indexing rotational angle.

Abstract: A bypass feeder of the type comprising a tank having a closeable rounded top opening, an inlet and outlet opening positioned on the side of the tank, includes a rectangular frame filter bag holder dimensioned to fit inside the tank, the frame having its bottom portion fitted with a plug having a tapered round opening, an L-shaped inlet pipe adapted to be received into the tapered opening of the plug, a filter bag dimensioned to fit over the filter bag holder and having a drawstring adjustable bottom opening for fitting the opening tightly against the plug. The improvement of the invention resides in the filter bag also having an open top and a sealing ring adapted to engage the open inside top of the filter bag and force seal it against the inside of the closeable rounded top opening.
