Title: Control panels and traffic signals and the like incorporating such control panels
IPC: G08G1/095
Filed: 1970-08-26
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.

Patent GB-436608-A (GB)
Abstract: 436,608. Copying images on lenticular films. OPTICOLOR AKT.-GES., Glarus, Switzerland. July 5, 1934, Nos. 19827 and 19828. Convention dates, July 6, 1933 and Nov. 10, 1933. [Classes 97 (i), 98 (i), and 98 (ii)] In a process of copying images from lenticular films onto lenticular blank films, two or more objectives co-operating with plane reflecting surfaces are used to produce registering images from one film upon the other film. Preferably, the objectives are seen from the films at positions corresponding to those which are occupied by the zones of the multicolour filter during the taking or projecting of the films. In one form, two objectives 3, 4, Fig. 1 are used in conjunction with parallel plane mirrors 5, 6, 7, 8, on opposite sides. The objective 3 copies the images corresponding to the central and one lateral filter zone of the film 1 onto the film 2, the other lateral zone being copied by the objective 4. A screen 11 is provided to cut off direct light from the objective 4. In a modified form, a second objective may be arranged on the opposite side of the objective 3 to the objective 4. The mirrors may also be spaced further apart so that the centres of the lateral objectives do not coincide with the centres of the filter zones. The arrangements may be used for copying with change of scale. An arrangement with two objectives and pairs of mirrors arranged symmetrically to the line joining the centres of the original and copy films may be used for copying stereoscopic images. In a further modification, the mirrors are arranged on one side only of the objective and are not parallel to the optical axis. In one form, three objectives 33, Fig. 11, are arranged at the corners of a triangle and each is combined with a pair of mirrors 35, 36, the whole being mounted in a single casing. Alternatively the objectives may be arranged between parallel mirrors. If the lenticular elements on one film are at right angles to those on the other film, the objectives may be arranged as shown in Fig. 17, in which the chain lines represent the separating edges of the filter zones of the original and copy films. The Specification as open to inspection under Sect. 91 describes also the application of the process to copying to and from films not bearing lenticular elements. A construction of diaphragm for use with each objective in the system of Fig. 11 is also described. This comprises a number of blades forming an elliptical opening and provided on the outer periphery with noses bearing on an operating ring, the plates being moved towards one another in a straight line by turning the ring. This subject-matter does not appear in the Specification as accepted.
