Rotatable Window for Vacuum System

Improved efficiency in the use of mass spectrometer systems is achieved by employing a rotatable translucent viewing disc in place of the stationary viewing windows employed in the usual systems.

The rotatable window has the advantage that, when a particular exposed portion becomes coated through usage, it can be rotated to a new viewing position. In the single viewing window of the usual systems, a considerable amount of down time is experienced due to the necessity of cleaning it.

Rotatable disc 1 is rotatably supported on shield 2 having viewing port 3. this is in line with external viewing port 4 located in outer wall 5 of the vacuum system. Window 1 is manually rotated by ratchet 6, drive pawl 7, connected by linkage to thumb screw 8 disposed on the outside of the vacuum system.
