Abstract: A sealing mechanism for sealing an entrance aperture includes a flange with an interface defining an entrance aperture. A first drive shaft and a second drive shaft are coupled to a first drive element. A first linear rail is positioned on a first side of the entrance aperture. A first door linkage is pivotally coupled to a door, and coupled to the first linear rail and to the first drive element. A first pivoting cam is coupled to the first door linkage. A first cam latch is positioned on the first side of the entrance aperture and sized to receive the first pivoting cam. Contact between the first cam latch and the first cam urges the door inwardly at an angle relative to a direction of movement of the door to urge the door to contact an outer edge of the interface defining the entrance aperture.

Abstract: An inspection system includes a housing having a cavity which defines an inspection zone, and a positioning device within the inspection zone which provides positioning of a specimen within the inspection zone. The inspection system includes a sensor system for inspecting the specimen, and an entrance aperture formed in the housing. The entrance aperture may be sized to permit the specimen to pass through the entrance aperture. The inspection system also includes a sealing mechanism, such as a door, which cooperates with the positioning device. The sealing mechanism is operatively coupled to the housing and selectively positionable between open and closed positions. The open position permits the specimen to pass through the entrance aperture, and the closed position seals the entrance aperture to effectively isolate the inspection system.
