Abstract

27,468. Soc. Lipmann FrÞres. March 1, [Convention date]. Dials.-The figures or other indicating-marks on dials for watches and clocks are formed by piercing in the dial small holes, Fig. 3, or continuous slots, Fig. 4, in the dial, which is then superposed on a backing provided in the required places with luminous material. The holes may be edged with dark paint, to render the numerals more plainly visible in daylight; or two sets of figures may be provided, as shown in Fig. 4, one for use in the day-time, the other for the dark. The arrangement is applicable to chronoscopes, the holes in the moving dials in this case passing successively over the luminous parts fixed in the rear. The Specification as open to inspection under Section 91 (3) (a) states that the invention is applicable to dials of all kinds, and also that the luminous material may be disposed in recesses forming the numerals or other indicating-marks on the dial. This subject-matter does not appear in the Specification as accepted.
