Abstract: 1,141,777. Cobalt and nickel extraction. ELDORADO MINING & REFINING Ltd. 17 June, 1966 [21 June, 1965], No. 27243/66. Heading C1A. Cobalt and nickel values are recovered from an acid lead solution by liquid-liquid separation using a salt of an organo-phosphoric acid compound of formula where R is H, substituted or unsubstituted alkyl, aryl or aralkyl, not more than one R being H and each R group other than H containing at least 8 C-atoms and the molecule containing at least 12 C-atoms, dissolved in a water-immiscible solvent. The leach solution is prepared by treating ore with nitric or sulphuric acid and removing elements such as Fe, As and particularly Cu by pH adjustment. The organo-phosphoric acid composed may be an alkali-metal or ammonium salt of di - (2 - ethylhexyl) phosphoric acid, heptadecylphosphoric acid, dodecylphosphoric acid, di- (1-methylheptyl) phosphoric acid, diisocytylphosphoric acid di - (2 - ethyl - 4 - methyl - pentyl) phosphoric acid, di - (2 - propyl - 4 - methyl - pentyl) phosphoric acid, octylphenylphosphoric acid, or the isooctyl or stearyl derivatives of alkyl acid phosphates. The compound is dissolved in toluene, carbon tetrachloride, benzene, chloroform, methylene chloride, 2- ethyl-hexanol, kerosene or naphtha to which either tributyl phosphate or isodecanol is added as an emulsion inhibitor. The cobaltloaded organic phase is separated from the aqueous phase and scrubbed with cobalt sulphate or nitrate, or dilute sulphuric or nitric acid to remove nickel before being stripped with sulphuric, nitric or hydrochloric acid to produce a cobalt salt. The nickel is recovered from the original raffinate by crystallization.

IPC: B05B3/04
Filed: 1926-11-06
Abstract: 261,037. Siemens - Schuckertwerke Ges. Nov. 7, 1925, [Convention date]. Rotary apparatus.-In apparatus for distributing water for irrigating by spraying in which one or more jets are projected in a radial direction from a nozzle head rotated by means of a vane wheel placed in front of the nozzle, the nature of the impact of the water upon the vane wheel is periodically varied by means of a curved member so as to obtain an irrigated area differing from a circle, for example a rectangle. Fig. 1 shows a form in which the nature of the impact of liquid from a rotating nozzle 1 upon the vane wheel 3 is varied by varying the admission of air through a pipe 6 by means of a cock 7 operated by a lever 8 engaged by a cam 10 on a fixed pipe 2. The nozzle is rotated by gearing 5 driven by a vane wheel 3 mounted in the path of the jet. In a modification, the height of the vane wheel is altered relatively to the jet by means of the cam mechanism. The air supply may be under pressure, or the nozzle may be so formed as to draw air into it, as by narrowing the throat of the nozzle and introducing air at the narrowed part. In the form shown in Fig. 5, an ejector body 13 opens into the rotating nozzle 1 and the fixed pipe 2 is provided with openings 15 through which air is drawn, the amount being varied during rotation by the lower edge of the nozzle being recessed at 16. An annular valve 17 controls the air inlets. In the form shown in Fig. 6, a second mouth piece 18 is mounted concentrically with the nozzle 1, the space between them forming an auxiliary water jet which may be regulated as in the other modifications. The Specification as open to inspection under Sect. 91 (3) (a) states that the range of the water jets may be regulated by other means such as baffles or needle valves. This subject-matter does not appear in the Specification as accepted.

Abstract: 408,601. Spray carburetters. SEARLS, E. C., Seyssel Street, Cubitt Town, London. Oct. 7, 1932, No. 28026. [Class 7 (iii).] To heat the mixing chamber, exhaust gases are led through a pipe or conduit 2a to an annular space 6 disposed between a Venturi tube 4 and its housing 3, and the gases enter the mixing chamber through apertures 7 in the tube, arranged at the point of emission of fuel from the jet 5. The apertures may be arranged radially, or as arcuatelyshaped passages to impart a spinning motion to the gases in the mixing- chamber. At starting, petrol is supplied from a float chamber 14 through a valve 11 and a tube a to a starting-jet 10, and the supply of exhaust gases may be cut off. During normal running, the valve 11 is turned to supply heavy fuel from a float chamber 13 to the jets 10, 5. The valve 11 may be arranged so that the petrol flows at starting, both to the jet 10 and to the float chamber 13. The inlet manifold may be heated either by casting it integral with the exhaust manifold, or by arranging it alongside the exhaust manifold and surrounding the manifolds with an asbestos wrapping.

Title: Television receiver

Abstract: 1,215,024. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 June, 1968 [16 June, 1967], No. 28157/68. Heading H4F. In a television receiver the brightness is stabilized by a reference signal level occuring during the blanking interval by mesuring the CRT beam current during this interval by means of a circuit connected to the CRT gun and generating a corresponding control signal which is used to stabilize the beam current, the measuring circuit being by-passed during the picture content line interval by closing an electronic bidirectionally conductive switch. As shown, Fig. 1, a colour television receiver comprises circuits 1 which separate the luminance, chrominance and synchronization signals (Y, Chr, S) a beam indexing CRT 17 and a matrix 15 which combines the luminance and chrominance signals Y, Chr and an index signal I from photo-multiplier 19 to produce a writing signal W which is applied to the grid of the CRT via amplifier 27. The writing signal W contains a reference level R during the blanking interval and the beam current of the CRT is measured during the occurence of this level by applying the voltage developed across resistor 37 to amplifier 67 and storing a proportional voltage on capacitor 77. During the picture line interval resistor 37 is by-passed by a bidirectionally conducting switch 39 comprising a diode bridge driven by signals produced by time base circuits 45 which also provide the horizontal and vertical deflection signals for the CRT 17. A second bidirectional switch 79 is connected between the storage capacitor 77 and the grid of amplifier 27 and this switch is also closed only during the picture line interval to apply the stored voltage as bias to the amplifier. In a second embodiment, Fig. 2 (not shown), the beam indexing tube is replaced by a three gun tube the grids being fed with the red, green and blue signals via separate amplifiers (129, 131, 133). The cathodes are connected to separate beam-current stabilization circuits (157, 159, 161) each comprising a transistor (191) forming a current amplifier which measures the beam current during the occurrence of the reference level and a network to apply a corresponding bias voltage to the grid of amplifier (201). During the picture line interval the measuring circuit is by-passed by a bidirectional switch (183) comprising a transistor (187) which is bottomed by a base current provided by time base circuit (177).
