Title: Improvements in and relating to means for dispensing ink from ink containers such as ink wells and the like
IPC: B43L25/00
Filed: 1932-02-09
Abstract: 394,748. Inkwells. WHITE, E. G., 10, Hazlitt Road, West Kensington, London. Feb. 9, 1932, No. 3838. [Class 146 (iii).] An inkwell comprises a container closed with the exception of a narrow flattened opening of such a size and/or profile as to obstruct the introduction of the nib portion of a selffilling fountain pen into the ink sufficiently to prevent the abstraction of any substantial quantity of ink from the container when the self-filling apparatus of the pen is operated, but to admit a nib profiled transversely to pass through the opening easily to abstract sufficient ink for writing purposes. The conical part c of the safety inkwell a, Fig. 1, is flattened towards its lower end to prevent the sealing of the end of a fountain pen which might be inserted and terminates in a flattened tube d of such width and breadth that only a particular form of nib can be inserted therein. The nib employed may be shown as in Fig. 10, having a flat portion g with narrow wings h and a shank n which may be curved or flat for introduction into a holder o, the point k being split at l and cut at m, and if desired provided with ink-retaining corrugations r. In a modified form of inkwell provided with a tubular extension to receive a stopper, the container is formed with a flat top having a narrow slit which may be straight, curved, or V-shaped to correspond to the nib used, and to prevent the sealing of the end of a fountain pen, the container is made shallow by raising the bottom below the filling slit, or by forming this slit in a nipple or depression in a convex or concave top. Alternatively, the tube d may be replaced by a narrow slit, or it may be curved or bent in transverse section to correspond to the shape of the nib.

Title: Improvements relating to apparatus for generating colour television signals, or for receiving such signals
Inventor: STILLWELL PETER FREDERIC THOMA
IPC: H04N11/00
Filed: 1950-02-16
Abstract: 689,785. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 16, 1951 [Feb. 16, 1950], No. 3938/50. Class 40 (iii). In a colour television system, colour separation is effected by means of a colour mosaic, the mosaic being maintained stationary and the optical path being displaced with reference to the mosaic so that light from each element of the image is passed successively through differently coloured elements of the mosaic. Thus in Fig. 1, object 15 is projected on to target 4 of signal-generating tube 1 by way of optical system 13, rotating disc 14 and colour mosaic 18. Disc 14 is formed with reflecting surfaces 20 (see Fig. 2) mounted in groups of three with surfaces 20a, 20b, 20c stepped along the axis of the disc so as to provide displaced light paths 21a, 21b, 21c. The disc is driven by synchronous motor 17 powered from a supply 11 which also synchronizes the frame scanning generator 10. The motor rotates the disc so that the reflecting surfaces scan the colour mosaic at the frame rate and the angular extent of each surface corresponds to the height of the scanned patch. As the disc rotates, succeeding images are subjected to a displacement in the horizontal (line) direction equal to the separation between successive columns (see Fig. 2) of colour mosaic 18, the cycle of displacement repeating every three images. A step-waveform generator 22 which is likewise synchronized from supply 11 generates a periodic waveform 23, its period being three times the frame period. The step-wave is superimposed on the line scan waveform fed from generator 9 and displaces the scan patch horizontally by the same amount as the displacement produced by disc 14. In receiving apparatus, tube 2 is replaced by an image-reproducing cathode-ray tube and the step-wave is utilized to displace the scanned patch on the tube screen whilst disc 14 effects similar compensatory displacements to maintain the projected image stationary on a suitably placed screen. A modified image displacer, Fig. 5 (riot shown), comprises a wheel made up of transparent sections having parallel faces inclined at different angles. The sections may alternatively be replaced by prisms. A mirror carried by a piezo-electric crystal or apparatus in which the refractive index of a medium is varied by an - electric field may also be employed to displace the image. A modified colour mosaic, Fig. 4 (not shown), is assembled with the elements in succeeding rows displaced by one-third of an element and the colours arranged so that any two contiguous elements are of different colour. With this mosaic, a complete cycle of operation involves nine displacements of the image. The displacement to produce colour analysis may occur in the frame direction instead of the line direction. Specification 442,666 is referred to.
