Abstract
359,921. Theatrical appliances. WHITING, W. J., Potmae Park Apartments, Washington, U.S.A. April 26, 1930, No, 12937. [Class 132 (i).] Various optical effects are produced by utilizing lights differing partly or wholly as to their spectral compositions but having the same spectral centre of gravity, this centre being defined as the centre of gravity of the area enclosed between the luminosity curve and its wavelength axis. For example, the composition represented by Fig. 8 has a bright band II in the blue-green and a bright band IV in the red, while the wholly differing composition of Fig. 10 has a bright band I in the violet and a bright band III in the yellow. It is stated that these two compositions have the same centre of gravity C.G. and appear alike to the eye, both being substantially white. If a scene is illuminated by these two compositions successively changes will appear therein, depending on the colours of objects in the scene and the colour of the background, although there is no apparent change in the nature of the illumination.
