Title: Improvements in light modulating devices

Filed: 1939-01-24
Abstract: 526,875. Light modulating. I.M.K. SYNDICATE, Ltd., NAGY, P., and GODDARD, M. J. Jan. 4, 1939, Nos. 2465 and 2587. [Classes 39 (i) and 40 (iii)] A light modulating device intended especially for television receivers comprises a transparent medium capable of bearing mechanical oscillations therein, means for producing a plurality of independent oscillations in said medium, and an electron beam for successively exciting said oscillation producing means. As shown in Fig. 1, the transparent medium is constituted by a fluid in a container 17 in the base of which a line of piezo-electric crystals 18a is arranged having a common metal layer 19 on one side against the fluid medium and separate metal strips 20 on the other side connected to separate metal strips 21 in a cathoderay tube 10 provided with means for oscillating the electron beam along the line of strips 21 and for modulating the intensity of the beam or the deflection of the beam laterally of the line of strips 21. The electron beam charges the strips 21 directly or preferably by secondary emission, in which case a grid system of wires 22 at anode potential is provided along and adjacent the line of strips 21. The tube is arranged to provide a flat beam and to control this beam in a generally well-known manner, being provided for these purposes with a cathode 11, a control grid 12, an anode 13, a lining 14 connected to the anode, a focusing coil 15, and deflecting plates 16. To improve the efficiency of the light modulating device, the transparent medium is divided by horizontal surfaces 24 designed to produce reflection and resonance, and the electron beam may be made to apply a succession of impulses to the piezo-crystals at a frequency corresponding to the resonance frequency of the piezo-electric crystal. Various other details of the light modulating cell are also described. In use in a television receiver, the electron beam is modulated according to the received image signals, and is oscillated at line frequency ; the separate oscillations produced by the separate piezo-electric crystals correspond to the intensities of the image points of a line and are made to persist for the duration of scanning of a line. This image line is reproduced on a screen VS, Fig. 3, by light from a source X modulated by passage through the transparent material in the container 17. Successive lines of the image signals produce successive modulations of the line of light ; and the modulated lines of light are successively displaced by a mechanically rotated mirror drum SS to reproduce the image frame on the screen VS.

Title: Process for the manufacture of halogen-methane sulphonic acids and their salts
IPC: C07C309/06
Filed: 1935-01-28
Abstract: Halogen-methane sulphonic acids and their salts are prepared by reacting a mercuri compound of a methane sulphonic or halogen-methane sulphonic acid with a halogenating agent; preferably in the presence of a solvent or diluent.  The mercury halide obtained can be removed and the mercury and halogen recovered.  In examples: (1) iodine is added to an aqueous solution of the sodium salt of mercury-bis-diiodomethane sulphonic acid at 60 DEG  C.  Mercuric iodide precipitates and the sodium salt of triiodomethane sulphonic acid is crystallized from the solution.  The sodium salt of diiodomethane disulphonic acid is obtained similarly from sodium hydroxy-mercury-monoidomethionate. The sodium salt of mercury-bis-diiodomethane sulphonic acid is obtained by boiling the sodium salt of diiodomethane sulphonic acid with freshly precipitated mercuric oxide in dilute caustic soda, sodium hydroxy-mercuric-diiodomethane sulphonate being first formed and the bis salt on continued boiling; (2) sodium triiodomethane sulphonate is obtained from sodium-hydroxy-mercury-diiodomethane sulphonate and iodine as in (1); (3) mercuric oxide is boiled with a solution of sodium diiodomethane sulphonate and caustic soda.  After neutralization, iodine is added and the mixture treated as in (1) to yield sodium triiodomethane sulphonate; (4) alcoholic bromine solution is added to a hot aqueous solution of sodium hydroxy-mercury-diiodomethane sulphonate.  The solution is concentrated in a current of nitrogen in vacuo to remove mercuric bromide and yield sodium bromo-diiodomethane sulphonate; (5) a solution containing sodium hydroxy-mercury-dibromomethane sulphonate, prepared from sodium dibromomethane sulphonate, mercuric iodide and dilute caustic soda, is treated with iodine to yield sodium dibromo-iodomethane sulphonate; (6) the sodium salt of mercury-bis(methane-trisulphonic acid) is heated with iodine and water to 120 DEG  C. in a bomb tube.  Mercuric iodide is removed, the solution concentrated, and methanol added to precipitate sodium iodomethane trisulphonate.  The initial mercury compound is prepared from sodium methane trisulphonate, mercuric iodide, and dilute caustic soda; (7) sodium hydroxy-mercury-dibromomethane sulphonate in water is treated with chlorine, the solution evaporated in vacuo, the residue taken up in water, treated with H2S to precipitate the mercury, and sodium chloro-dibromomethane sulphonate obtained by crystallization.

Title: Improvements in or relating to telephone or like systems
IPC: H04Q1/444
Filed: 1944-02-19
Abstract: 571,908. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., GILLINGS, C., and BEALE, C. E. Feb. 19, 1944, No. 3129. [Class 40 (iv)] In a system in which voice-frequency impulses arriving at the incoming end of a junction are repeated forward as direct current impulses, the first impulse of each train is not repeated, but serves only to disable the transmission path between the junction and the incoming selector in order to guard against backward surges which might affect the echo-suppressors, an additional direct current impulse being generated at the end of the train and the disablement being maintained throughout the train and for a further period sufficient to cover a hunting operation. A VF seizing signal energizes relays L, NR, AR (not shown), of which L introduces the combined loss pad and termination YA ... YE, while NR connects - up the line relay A of the incoming selector. Relay AR releases in response to each numerical impulse, and relays EB, EM are so arranged that EB is energized at each break of AR and short-circuited at each make, whereas EM is energized at each make and short-circuited at each break. At the first break, EB connects up SG which opens the transmission path and at the subsequent make EM connects up C which completes the usual loop circuit for relay A, the succeeding impulses being repeated by AR. At the end of the incoming train, EB, EM relapse in turn and generate an additional impulse in the outgoing loop circuit. The relapse of C, SG follows and the transmission path is restored. The release lag of EB is such that the make period preceding the locally generated impulse is not long enough to release the C relay of the selector, while the lag of EM is such that it terminates an outgoing impulse ahead of AR if the break period imposed by that relay is unduly long.

Abstract: 628,843. Hydraulic machines. ANDERSON, J. Feb. 3, 1947, No. 3173. [Class 69 (ii)] In a machine tool or other machine having an hydraulic feed operated by oil circulated under pressure by a pump, a thermosensitive device, sensitive to the temperature of the oil being circulated, operates as the temperature rises to pass part of the oil to a body of oil which supplies make-up oil to that being circulated, the amount of make-up being such that the temperature of the circulated oil, and therefore its viscosity, is kept substantially constant. As shown, part of the oil circulated by a pump b through a relief-valve e, pipe l, chamber h and pipes m o, back to a sump i, is passed as the 'oil temperature rises by a valve g operated by a thermosensitive device f, to a part of the sump which communicates through a restriction j with the part from which the pump draws. A jack a forms part of the hydraulic feed of a machine tool and to operate the jack a control-valve c is opened to connect the relief valve e through a metering valve to the righthand end of the jack. To reverse the jack the control valve is operated to connect the righthand side of the jack piston to a pipe n<SP>1</SP> leading to the sump.
