    Sextant averager
    From: Gary LaPook
    Date: 2010 Oct 10, 17:43 -0700

      Here is the patent on the Dreimel-Black averager used in the Kollsman
    sextant. The patent used an A-10 sextant to illustrate the invention.

    The following post describes the operation of the averager but has it
    wrong since the ball moves from the center to the edge of the rotating
    disk at a constant rate driven by clockwork and the rotating disk is
    turned by the altitude knob which is exactly the opposite of this
    description.
