Abstract: 403,831. Displaying ; time - tables. RAPID PUNKTPLAN AKT.-GES., 30, Centralstrasse, Lucerne, Switzerland. Feb. 16, 1933, Nos. 4808 and 4809. Convention dates, Feb. 17, 1932 and Feb. 26, 1932. [Classes 3 (i) and 3 (ii).] A method of and apparatus for emphasising a mark or a series of marks on an original graphical representation consists in superposing the original representation on a secondary member or members exhibiting several series of inter-related data such that by turning, sliding, or adjusting a secondary member in accordance with certain marks for such adjustment only one of the series of inter-related data appears through openings (either complete or transparent) in the principal member, one of the said secondary members carrying a multiplicity of dots, lines, contacts or the like complementary to the graphic representation for the purpose of emphasising certain details thereof. In the map arrangement shown in Fig. 10, the air route from Munich as a centre to any town marked on the map is so indicated ; the position of the towns are marked by circular holes on a stationary map sheet A <1>, while upon a movable part C<1> dots are marked which correspond with their respective holes on the map. To find any desired route the movable part C<1>, which carries an alphabetical list of the places at its top edge, is adjusted longitudinally until the desired name registers with an opening O<1> in the map A', when the holes and dots of the corresponding route will register and the dots which are preferably coloured show through the holes to indicate clearly from all other routes on the map the particular route desired. Through an aperture in the back sheet D<1> which is attached to the sheet A<1>, there appear simultaneously indications as to times of departure and arrival and other information relating to the journey. The textual sections may be changeable, and carried by separate sheets, one or more of which may be attached to the member C<1> and which may be visible at front or back spaces. Alternatively the cover sheet D<1> may be extended as shown beyond the map sheet A<1> and carry on its front position a number of parallel strips such that the strip immediately to the right of the sheet C<1> bears information appropriate to the place indicated at the opening O<1>. This extended portion of the sheet D <1> may also be folded over to serve as a cover. Advertisements are printed on the available places of the members A<1>, C<1>, D<1>, and the slider C<1> may be held in adjusted position by a catch and notch or like device. The materials of the sheets A<1> C<1> may be transparent in which case the marks on the movable member may be made opaque to register with and show through transparent parts left in the fixed member ; alternatively the two sheets may be similarly printed but the adjustable member is more heavily drawn and an opaque shutter may be interposed having an aperture which is caused to register with the notch desired. If both sheets are opaque and provided with transparent marks, these, when brought into register, may reveal a different coloured backing or a source of illumination provided at the back ; in the latter case the device may be enlarged by optical projection. The two members may be in the form of discs either fixed and with a rotatable shutter member, or one may be rotatable relatively to the other. In a modification lamps situated beneath apertures at the points to be emphasised are illuminated by adjusting a sliding member relatively to a fixed member. Each member carries contacts corresponding to the points to be emphasised such that when the slider is appropriately adjusted the particular contacts are closed and upon depressing a switch the lamp behind any desired point is illuminated. Alternatively, hydraulic means may be employed. In a further modification applied to a cigarette or like carton, the sliding member of the carton is provided with information concerning horse-racing, while the relatively fixed outer casing is formed with window apertures and holes adjacent which are printed the names of the race-courses. Adjustment of the two members causes a horse's name to appear at one window, while coloured dots show through the holes to indicate the courses at which the horse has raced, and at a large central aperture the results of such races are shown. The device may also be applied to indicate the places on a map, represented on the outer cover of the box, at which tobacco is grown, and the proportions used, in the contents of the box.
