Convention date, April 26, 1934. [Class 40 (v)] A radio beam for use in air-navigation is simultaneously modulated in different ways by interposing in its path ionized gas tubes of the kind described in Specification 425,671. As shown in Fig. 3, two sets of ionized gas tubes 43, 45 are interposed in the path of the beam from a parabolic projector 5, and are modulated (a) by " interlocked A-N signals from generators 77, 61 in series with keying-devices A, N when the switches 57, 73 are in the position shown, or (b) by constant-frequency oscillations from the generators N1, N2 when the switches 57, 73 are thrown over. In addition a second pair of ionized tubes 85, 87, set at right-angles to the first, impose further signal frequencies M1, M2. In this way the beam may be variously modulated in the different sectors as shown in Figs. 4 and 5. In reception, Fig. 7, the rectified signals are fed through vibrating-reed filters N1, N2, M1, M2 to opposed coils which deflect indicating-needles 135, 137 when the craft leaves the centre of the beam. For landing, the beam is inclined at the proper angle, and the filters, Fig. 8 (not shown) control through a solenoid the position of a disc so that it moves away from a centre mark when the craft deviates from the proper landing angle. The horizontal course is meanwhile followed by listening to the A-N signals in a pair of headphones 2 whilst the wings are kept level by observing the position of an indicator relative to an artificial horizon.

The phase changer 8 is inserted to ensure that a tone passing via 8, 9, 12 is in phase with a tone via 1, 11, 12 if their frequencies are equal or octavely related.
Patent GB-542704-A (GB)
Title: Improvements relating to photographic emulsions
IPC: G03C1/04
Filed: 1940-07-19
Abstract: 542,704. Photographic emulsion. KODAK, Ltd. (Eastman Kodak Co.). July 19, 1940, No. 11909. [Class 98 (ii)] A photographic emulsion is prepared by forming silver halide or a mixture of silver halides in an aqueous solution of a silver halide dispersing agent other than gelatine, such as a watersoluble hydrolysed starch acetate, a water-soluble co-polymer of maleic anhydride and vinyl acetate, a water-soluble condensation product of such a polymer with aniline, a water-soluble cellulose ether such as methyl or ethyl cellulose or gum arabic, and a polyvinyl protective colloid is added to the dispersion so formed. The protective colloid may be polyvinyl alcohol or a polyvinyl ester such as polyvinyl acetate. A watersoluble polyvinyl compound may be used and a gelling agent incorporated in the emulsion. Polyvinyl acetate of acetate content (calculated as vinyl acetate) from 0.5 to 5 per cent may be added in aqueous solution, while polyvinyl acetate of acetate content from 59 to 71 per cent may be added in solution in a mixture of water and an organic solvent. Part of the polyvinyl compound may be present in the solution of the silver halide dispersing agent, and the remainder added subsequently, or in a modification all the polyvinyl compound may be present in the dispersing agent solution. Gelling agents such as # naphthyl-salicylamide, gallic acid, resorcinol, or #- naphthol may be added to the emulsion at a raised temperature (40-90‹ C.) and the emulsion gelled by cooling. An increase in the amount of dispersing agent used gives greater contrast in the resulting emulsion. The emulsions may be prepared by running aqueous solutions of silver nitrate and alkali metal halide into an agitated dilute aqueous solution of the dispersing agent, and then adding an aqueous solution of the polyvinyl compound and thoroughly mixing. The emulsion may be digested. An organic solvent may be added to the developing and fixing baths. With a paper support, the amount of sensitizing used should be insufficient to cause staining. The emulsions may be used in black-and-white or in colour processes. In an example (1), an aqueous solution of starch acetate is rapidly stirred together with an aqueous solution of silver nitrate and an aqueous solution of potassium bromide, potassium chloride, and potassium iodide at 80‹ F. An aqueous solution of polyvinyl acetate of acetate content less than 5 per cent is added and stirring continued. The resulting emulsion is sensitized with 2:3<SP>1</SP>-diethyl-4<SP>1</SP>-methyloxathiazolocarbocyanine. The procedure in examples (2), (3), (4), (5) and (6) is similar, with the use as dispersing agents of ethyl cellulose, methyl cellulose, gum arabic,' the co-polymer of maleic anhydride and vinyl acetate, and the condensation product of the co-polymer of maleic anhydride and vinyl acetate with aniline respectively. A plasticizer such as monoacetin may be added. Specifications 525,085, [Group IV], and 527,283 are referred to.

Filed: 1946-04-17
Abstract: 610,969. Velocity-modulated tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 17, 1946, No. 11909. Convention date, Dec. 26, 1940. [Class 39 (i)] An amplifier for use at frequencies of about 300 mcs./sec. comprises a velocity modulator, a repeller electrode and an electron multiplier. In the Figure, the electrons pass from the cathode F and control grid G to the electrodes D1, D2, M which form a velocity modulation system. Electrode A1 is near cathode potential and thus passes the fast electrons, but repels the slow ones back to D2. The electrons then impinge on the secondary emitting electrode C2 and the secondary electrons are focused by the ring electrode B2 which is near cathode potential; the process is repeated and the output taken from A3. The electrode spacing may be such that the transit time of the electrons between two cathodes C2 is half a period. The repeller electrode A1 may itself be a secondary-emitting grid. In another form, Fig. 2 (not shown), the electron multiplier is of the zig-zag type and the electrodes C2 are parallel plates.
