  • Patent number: 7934535
    Abstract: A centrifugal casting method and apparatus for casting molten metal into a mold. The casting apparatus includes a housing provided with a bottom surface and a retaining wall for minimizing a number of projectiles that escape the housing during casting operations. A prime mover is provided for imparting a centrifugal force on the molten metal, and an arm is coupled to the prime mover adjacent to a proximate end to be rotated about a rotational axis and to support a cradle for receiving the mold adjacent to a distal end. A crucible is to be coupled to the arm for supporting the molten metal to be cast into the mold, while a catch surface is disposed between the arm and the bottom surface of the housing to collect molten metal that is cast but not received within the mold.

  • Patent number: 5388989
    Abstract: An occlusal sculpting tool (10) includes a grip portion (11) having a generally central axis and supporting an occlusal sculpting portion (12) at one end thereof. The occlusal sculpting portion (12) has an extension bar (30) affixed at one end thereof to the grip portion (11) and an occlusal tip (31 ) affixed to the other end of the extension bar (30). The extension bar (30) has a plurality of angles therein such that the occlusal tip (31) is spaced from the grip portion (11 ) and generally aligned with the generally central axis of the grip portion (11 ).
