Abstract:

In the patent application light rays are provided in square wave form at uniform intervals. A source of light is provided within three cylinders. The first cylinder being stationary has an aperture extending 120 degrees. The second and third cylinders each have arcs extending 240 degrees, and rotate in opposite directions. In operation the device gives equal light and dark periods with a rise and fall time one-half the period of the full open and full close time. The length of the periods are dependent on the rotational velocity of the cylinders.
