Title: Improvements in or relating to electrodeposition of manganese
IPC: C25C1/10
Filed: 1944-11-29
Abstract: A solution of manganese sulphate and ammonium sulphate for use as electrolyte in the electrodeposition of manganese is treated at pH about 5.5-7.5 with aluminium sulphate in the proportion of not less than 0.4 lbs., calculated as anhydrous aluminium sulphate to each 100,000 lbs. of the solution in order to precipitate silica, which is then removed from the solution.  A preferable range of proportions is 10-160 parts by weight of anhydrous aluminium sulphate to 100,000 parts by weight of solution.  The aluminium sulphate may be added to pH 5.5-6.5, the pH then being raised to 7.2-7.5; or part of the aluminium sulphate may be added at pH 5.5-6.5, the remainder being added at pH 6.5-7.5.  In an example anolyte containing 10-18 gms. per litre of manganese as sulphate and 120-180 gms. per litre of ammonium sulphate, pH 1-2, withdrawn from a diaphragm cell and digested with manganese ore to a manganese concentration of 20-50 gms. per litre. The pH is adjusted to 5.5-6.5 and iron, arsenic and antimony precipitated by air or other oxidizing agent.  Aluminium sulphate is then added, the precipitate formed being allowed to remain in suspension.  The pH is then raised to 7.2-7.5 and further aluminium sulphate added.  Ammonium sulphate is then added, precipitating cobalt, nickel, &c., together with aluminium hydroxide.  The purified liquid which should contain not more than 0.001 gms. per litre silica is returned for use as catholyte.

Abstract: 599,350. Intercommunication systems. BIAL, W. Sept. 17, 1945, Nos. 23894 and 26045. Drawings to Specification. [Class 40 (iv)] In a system in which a number of substations may be connected up for one-to-one inter-communication, for telephony or signalling, over a number of conductors less than the number of stations, a common return conductor is employed for all connections, and the other leg of each circuit comprises a number of conductors in parallel. In one embodiment having provision for 100 substations, 41 conductors are used, of which one is the common return conductor. The remainder are divided into two groups of 20 one of which is used for completing the selecting circuits and the other for the talking or signalling circuits. Each group is sub-divided into two sub-groups of 10, each numbered 1, 2 ... 9, 0. Connection to a wanted station is made over a circuit comprising one conductor of each sub-group in parallel, and the common return, the station being designated by the numbers of the conductors so employed. The substations are connected to the parallelled conductors over inductively coupled impedances designed to afford low impedance to currents flowing in the same directions in the parallel conductors, i.e. substation to line currents, but high impedance to currents flowing from conductor to conductor, thus reducing cross-talk between connections which employ the same conductor simultaneously as part of their circuits.

Filed: 1964-06-10
Abstract: 1,045,463. Colour television tubes. RADIO CORPORATION OF AMERICA. June 10, 1964 [July 9, 1963; Aug. 26, 1963], No. 24146/64. Heading H1D. The luminescent screen of a colour cathoderay tube includes, for generating an indexing signal, a continuous layer disposed on the screen of material which is radiation emissive when bombarded by electrons, and an array of deposits of material disposed on either or both sides of the continuous layer to intercept and either absorb or reflect radiations from the continuous layer. Aluminium layer 22 covers the layer 20 of repetitive groups of phosphor colour strips mounted on the inner face of envelope 12, and itself carries strips 26-e.g. of powdered carbon or aluminium-which are opaque to the U.V. or visible emission radiation of a superposed phosphor layer 24. Layer 24 carries a second array of spaced opaque strips 28, which are narrower than, and positioned centrally opposite to, strips 26, and may be of the same optically absorptive material as the latter, or of reflective material such as aluminium flakes. When the screen is scanned, the radiation emitted from layer 24 is rearwardly directed by reason of reflecting layer 22, and is of maximum, intermediate, and zero amplitude for incidence of the scanning beam on portions a, b and c respectively, providing a 3-level indexing signal (Fig. 2a, not shown) which is received by a photo tube positioned outside a window in the rear of the tube envelope. A 4-level signal may be produced by the arrangement of Fig. 3, in which the aluminium layer 22 and phosphor layer 24 are overlaid by spaced strips 32, 33 and 34, of decreasing degrees of opacity e.g. composed, respectively, of carbon, carbon/boron nitride, and boron nitride. A 4-level signal may alternatively be produced by an arrangement similar to that of Fig. 2, but in which strips 26 and 28 are only partially absorbing, and centrally disposed on each strip 28 is a narrower strip of fully opaque material. A 2-level signal may be produced by an arrangement similar to that of Fig. 3, in which each composite strip 32, 33, 34 is replaced by a single opaque strip.

Title: Electrical system for generating energy pulses
IPC: H03K3/57
Filed: 1963-06-18
Abstract: 1,037,698. Ignition systems. BENDIX CORPORATION. June 18, 1963 [June 29, 1962], No. 24254/63. Heading FIB. [Also in Division H3] A pulse generator, e.g. for the ignition system of an internal-combustion engine, comprises a capacitor 21 which is charged resonantly from a D.C. voltage supply through the primary winding of a transformer 17 and periodically discharged resonantly through the series combination of an inductor 25 and a silicon controlled rectifier 26 to whose gate electrode there are applied regularly recurring triggering pulses derived from a relaxation oscillator 54. In the circuit described the pulses developed at the secondary of the transformer 17 are applied through rectifiers 32 to build up incrementally the charge on a capacitor 35 until a discharge gap 37 breaks down whereupon current flowing in the primary winding 42a of step-up transformer 43 induces a sufficient voltage in the secondary 46 to cause spark-gap 50 to break down. The capacitor 35 is then discharged through the gap and the cycle recommences. Triggering pulses for the SCR 26 are derived from a relaxation oscillation 54 comprising timing circuit 56, 57 and unijunction transistor 61, the output pulses therefrom being applied to the gate electrode of the SCR 26 via transformer 74 and D.C. restoring diode 79. Commencing with capacitor 21 initially discharged, the capacitor charges resonantly to rather less than twice the D.C. voltage via the transformer 17. The SCR is then switched on and the capacitor discharges through the inductor 25 to a negative voltage of smaller value. When current in the inductor 25 attempts to change sign the SCR turns off, and a capacitor again charges through the transformer 17 but to a greater voltage than previously as it commenced from a negative voltage. Hence the amplitude of the voltage swing across the capacitor, and likewise across the primary winding of transformer 17, increases until limited by IR losses in the circuit, these being provided in the charging circuit by resistor 15. Where the voltage supply is of low value (e.g. less than 30 volts) so that there is little danger of overloading SCR 26, limiting resistor 15 may be omitted.
