Title: Improvements in television in natural colours
IPC: H04N3/04
Filed: 1931-11-02
Abstract: 391,781. Television. BAKER, T. T., The Hut, Hatch End, Middlesex. Nov. 2, 1931, No. 30321. [Class 40 (iii).] A colour television system employs at the transmitting and receiving ends a rotating scanning disc with a set of apertures or the like arranged to scan'the field once per revolution of the disc and in front of or behind the disc a second rotating disc formed with a number of transparent coloured portions and arranged so that during the rotations of the discs, each of the apertures co-operates in turn with each of the coloured portions. The scanning disc 1 has a single spiral 2 of apertures 5, 6 .. and a disc 4 with three transparent sectors of different colours is rotated at a speed about two and a quarter times that of the scanning disc so that during the rotations of the two discs, each aperture is associated with each of the coloured portions in turn. The light reflected from the object scanned may pass to a panchromatic cell or to a bank of cells with individual cells sensitive to the colours employed in the transparent disc. At the receiving end similar discs are rotated in an identical manner and cooperate with a source which emits light con. taining the various colours of the second disc. The transparent portions may be equal in number to the scanning apertures, with successive portions differently coloured according to a two-colour or three-colour system.

Abstract: 646,392. Directing, indicating, and locating faults ; capacitance and resistance measurements. GREENE, T. Nov. 29, 1947, No. 31624. [Class 37] Relates particularly to a system for locating faults in twin cables by connecting one cable 12 to a potentiometer 16 and forming a bridge by connecting the other cable 11 to a variable tapping 20, on the potentiometer 16 so that the location of a short circuit 10, or a break is indicated by the position of the tapping 20 at balance. According to the invention, the potentiometer 16 is associated with a scale holder 23 marked with a plurality of linear scales, and the length of the potentiometer is variable by adjusting contact 18 so that, e.g. the scale appropriate to the length of cable can be selected, e.g. by rotation of the holder, and the tapping 18 adjusted so that its indicator 21 lies on the selected scale at a marking corresponding to the length of the cable. As shown in Fig. 3, the scales 24, 25, 26, &c have the same zero, and the markings on each scale corresponding to the maximum of the preceding scale lie on a straight line 27. Where one cable is broken, the bridge indicates the ratio of the total capacities between the two broken lengths and the unbroken cable, Fig. 2 (not shown). The invention is applicable generally to measuring resistance or capacitance.

Title: Process for the preparation of monocyclic ketones, having more than nine ring members, and of their alkyl derivatives
IPC: C07C45/48
Filed: 1926-12-14
Abstract: 263,153. Naef, M., and Firmenich, F., (trading as Naef et Cie, M.). Dec. 15, 1925, [Convention date]. Addition to 235,540. Ketones; dicarboxylic acids.-The carbocyclic ketones of the parent Specification, having more than nine ring members, and their alkyl derivatives are prepared from the acids or anhydrides of the corresponding polymethylene dicarboxylic acids or their alkyl derivatives, in the presence of metals or metallic combinations of earths or . rare earth metals or their derivatives, including metals of the aluminium and titanium groups and those metals having atomic numbers 59-72 and compounds of uranyl but excluding cerium and thorium. Mixtures of dicarboxylic acids may be used to give mixtures of the ketones. In examples, (1) 3-methylcyelopentadecanone is prepared by heating the aluminium salt of 3-methyltetradecane-1 : 14-dicarboxylic acid or the free acid and aluminium to about 300-500‹ C., preferably in a vacuum, and the distillate after fractionation is treated with semicarbazide or other reagent for isolating ketones; or the acid may be heated with the addition towards the end of the reaction of erbium hydroxide in quantity not sufficient to convert all the acid into normal salt; (2) 4-methylcyclopentadecanone is obtained by heating a mixture of the didymium and lanthanum salts of 4-methyltetradecane- 1 : 14-dicarboxylic acid; or the acid is heated with the addition towards the end of the reaction of a mixture of the oxides of yttrium and erbium; (3) the erbium or uranyl salt of tetradecane-1 : 14-dicarboxylic acid is treated as in example (1) giving the corresponding ketone; or the acid is heated with the addition towards the end of the reaction of yttrium hydroxide; or the anhydride of the acid is heated with lanthanum hydroxide; or the didymium salt of this acid, prepared by adding to the solution of the sodium salt of the acid a quantity of didymium nitrate which is not sufficient to convert completely the acid into the normal salt, may be used; (4) the didymium salt of octadecane-1 : :18-dicarboxylic acid is heated, giving cyclononadecanone which has an odour corresponding to that of civetone; (5) a mixture of cyclopentadecanone and cyclohexadecanone is obtained from a mixture of the didvmium and lanthanum salts of the corresponding acids. These ketones on oxidation with chromic acid give each a dicarboxylic acid, e.g. cyclononadecanone gives heptadecane-1 : 17-dicarboxylic acid, The Specification as open to inspection under Sect. 91 (3) (a) gives two examples in which tetradecane-1 : 14-dicarboxylic acid or its anhydride is heated alone. This subject-matter does not appear in the Specification as accepted.
