    摘要： A protractor comprising a frame and a lever arm coupled thereto. The frame includes a first substantially straight edge and an elongate track adjacent to the first edge. The lever arm includes a second substantially straight edge and a channel which mateably engages the track of the frame. The channel/track combination couples the lever arm to the frame and permits the lever arm to rotate about an axis substantially orthogonal to the first and second edges. The first and second edges intersect at a point allowing a user to describe an angle between the two edges.

    摘要： A shutter section includes a stack of circular plates independently rotatable in a nest formed as a laminar formation of rings. The plates have central openings defining a light path. Four central plates in the stack are shutter guide plates with radial guide slots slideably holding shutter blades. Two outer pairs of plates are shutter drive plates connected by cams to the shutter blades. Simultaneous rotation of a shutter guide plate and associated shutter drive plate causes rotation of an associated shutter blade around the light path. Rotation of a shutter drive plate while the associated shutter guide plate is stationary causes the cam to move the associated shutter blade radially. The nest is enclosed by end plates. A motor section has motors driving pinions to rotate the circular plates. The circular plates, rings pinions and shutter blades are made of sheet metal. Shutters may be provided as interleaved pairs each driven by a pair of rotatable drive plates.
