Abstract
1328152 Signal device MINNESOTA MINING & MFG CO 26 Aug 1970 [27 Aug 1969] 41118/70 Heading G5C Opaque louvre plates 47 form a background for transparent indicia 45 situated in a signal device 10. Because of the angle at which the plates 47 are set, the amount of light from a source 43 which can pass between them to approaching traffic is reduced in direct proportion to the distance between the traffic and the signal device, whilst the amount of light transmitted through the transparent indicia 45 remains constant. Thus, at a point remote from the signal 10 the indicia cannot easily be distinguished from the background, as shown at 32, but the background diminishes in brightness as the traffic moves nearer to the signal until the indicia is seen lit against a virtually unlit background as shown at 34.
