Abstract: An adjustable power transmitting device comprising a rotary input shaft mounted for rotation about a first axis and an output shaft mounted for rotation about a second axis. The output shaft is also mounted for pivotal movement about at least two non-parallel axes so that the position of the output shaft can be adjusted about both of these axes. The input shaft is drivingly coupled to the output shaft so that the input shaft can rotate the output shaft in all positions of the output shaft about the two non-parallel axes.

Abstract: Wide angle spectacles comprising a spectacle frame and a wide angle lens system attached to the frame. The wide angle lens system includes at least first and second lenses. The lenses are arranged so that light passes in series first through the first lens and then through the second lens in travelling to the eye of the user. The lens system materially increases the peripheral vision of the user.
