  • Patent number: 5791472
    Abstract: A surgical tray for transport of a sharp surgical instrument is formed as a shallow, rectangular tray portion with an integral handle extending therefrom. The tray is made as a molded body of relatively lightweight material, such as plastic, and its dimensions are such that the tray portion is adapted to receive a single sharp surgical instrument. The tray portion has a rounded rim at its top end and the handle merges with the rim. The bottom of the tray portion can be formed with ribs to prevent slippage. The upper surface of the bottom of the tray portion can be formed with ribs to facilitate engagement and removal of the sharp instrument. The end of the handle can be flared to prevent slippage of the handle from the hand of the user.

  • Patent number: 4561592
    Abstract: Apparatus for attachment to an automated robot or other similar type of automatic machinery, for controlling paint spraying nozzles to provide additional degrees of freedom of spray direction and film coating, including a rack and pinion gearing housing attachable to the robot, one or more air cylinders mechanically linked to the rack and pinion gearing, a shaft rotatably coupled to the pinion gear and fixedly attached to one or more spray nozzles. Air activation of the air cylinders causes the pinion gearing mechanism to pivotally rotate about the shaft axis, rotatably positioning the spray nozzles in various preselected angular positions.
