  • Patent number: 6733267
    Abstract: A solid imaging apparatus and method produces an integral three-dimensional object from a multiplicity of cross sectional portions of the object by selectively exposing successive layers of a liquid photoformable composition to actinic radiation. The apparatus includes a vessel for containing the composition so as to present a free surface, and a movable platform disposed within the vessel below the free surface. Part of the composition is transferred above the free surface by lowering and raising a dispenser at predetermined positions located away from the platform. A doctor blade contacts the composition transferred above the free surface, and then moves over the platform to form a substantially uniform layer of the composition.

  • Patent number: 4791704
    Abstract: An arrangement for transferring poultry carcasses such as the carcasses of birds being chickens, ducks, turkeys and the like, from one position to another may be used to transfer the poultry carcasses from a killing conveyor to an eviscerating conveyor, for example. The arrangement can, however, be used to transfer poultry carcasses from any one conveyor to another conveyor. The arrangement includes a rotatably mounted plate and associated structure for imparting a rotational moment thereto. A plurality of sector members are pivotally mounted on or connected to the plate at a position offset or spaced apart from the rotational mounting of the plate. The rotational moment of the plate can be imparted to the sector members. Members are provided to limit or control the pivotal movement of the sector members relative to each other and to the pivotal attachment point.
