Definitions

• the present invention relates to a means of increasing the brightness of an object without having to provide it with additional light energy. It relates to the uses, adapted for this purpose, of the phenomenon of successive contrast.
• the phenomenon is all the more intense as the colored areas are brighter and nothing is removed or added to the invention by brightly illuminating these areas which then undergo an increase in brightness without additional light energy.
• the invention consists in making a succession of two complementary colors on the object to make it brighter in order to realize the following idea which is that of the invention: if we make sure that when a color disappears the complementary color which disappears takes its place, as in any case the eye already sees in this same place a fictitious color complementary to that which disappears, the superposition on the real color, of the fictitious color of the same shade, will give a range whose luminosity will beinstalld compared to what it would be under the only vision of the real range and that without having provided an additional light energy.
• the invention also consists simultaneously in the use of this method for producing visual alarm systems or advertising images that are attractive and attractive to the eye.
• the dimensions recommended here can vary in important proportions in particular to take account of the persistence of the luminous impressions on the retina of the eye.
• the axis of a cylinder twenty centimeters in diameter and twenty centimeters in height is materialized so that we can rotate the cylinder.
• the arrangement of the pads on the lateral surface is made on three parts delimited by the edges of the cylinder and by two circumferences parallel to these edges so as to form a median zone of fifteen centimeters in width and two lateral zones adjacent to the median zone, of widths each equal to two and a half centimeters.
• the middle zone is divided into four parts by sections of straight lines parallel to the axis of the cylinder. These four parts are alternately colored in the direction of rotation around the cylinder axis, one in pink the other in green.
• the lateral zones are colored one only in pink the other only in green.
• the advertising image is drawn on a rectangular and transparent planar support. We make sure that there is as much blank printing space as possible on the transparent support. Behind this transparent support and very close to it, that is to say almost adjacent, we tapssed a strip of endless stretched paper or canvas between two narrow cylinders on which it passes. These two cylinders are movable around their axes which are each placed parallel to one of the opposite edges of the transparent support. The strip is thus stretched and forms a flat part which moves parallel to the transparent support when the cylinders drive it by turning.
• the endless band is wider and longer than the frame of the image so as to frame it visibly through the support over a width of five to ten centimeters depending on the size of the drawing to be framed. It is divided on its visible face into parallel strips of five to ten centimeters in width by segments of straight lines parallel to the axes of the cylinders.
• the pink and green areas (constituted by the parallel bands of five to ten centimeters in width which one alternately colored in pink and in green) scroll under the image and under its edges.
• the physiological effect obtained thanks to the use according to the invention of the phenomenon of successive contrast draws the eye to the parts with enhanced brightness and thereby to the image which they dot and frame.
• the invention relates to colored areas, independently of the manner in which they are obtained and that the general inventive concept consists, once the colored areas are obtained, of increasing their luminosity by adequate use of the phenomenon of successive contrast, it is obvious that , without departing from this inventive concept, it is possible to color the areas of the rotating cylinder, in the case of the first example, or of the moving strip in the case of the second, either superficially or in the mass, and only if this mass is transparent or translucent you can use the remark made on page 1 lines 14 to 18 by placing a light source inside the cylinder or the strip.
