  • Patent number: 6902897
    Abstract: A biochip deposition system and method. The system comprises a deposit mechanism for depositing organic material in spots on a substrate; and a viewing system for detecting the spots on the substrate during a deposit operation and before the spots have dried, for determining if the spots have been correctly deposited, and if not, for generating a suitable output signal. The viewing system includes an illumination device for illuminating deposited spots at a relatively low angle relative to the substrate.
    Type: Grant

  • Patent number: 4880100
    Abstract: An adjustable workpiece rotating assembly for rotating a workpiece of any of a plurality of configurations at a workstation positioned along a conveyor system. Workpiece carriers attached to the conveyor system allow the workpiece to be positioned thereupon at a desired orientation relative to the work station. A mouth piece and base cup engage opposite ends of the workpiece and cause the workpiece to be rotated about a longitudinal axis thereof. The mouth piece and base cup are supported by a vertical displaceable rack which engage with a rotatably spur gear to allow the mouth piece and base cup to be translated simultaneously in the vertical direction to engage with a workpiece of any one of different elevations.

  • Patent number: 4787505
    Abstract: An adjustable workpiece carrier assembly for carrying workpieces on a conveyor system. Upstanding V-blocks used for supporting workpieces on the assembly, and are changeable so as to allow workpieces of different configurations to be supported thereon. By attaching a plurality of workpiece carrier assemblies to a conveyor system, an automatic conveyor system for conveying a plurality of workpieces in a desired orientation is possible. By simply changing the upstanding V-blocks to conform to the configuration of workpieces, workpieces of different configurations may be conveyed by the same conveyor system.
