Title: Improvements in or relating to processes for the purification of boron halides
IPC: C01B35/06
Filed: 1963-02-06
Abstract: A boron halide is purified by passing the gaseous halide, if necessary mixed with a reducing gas, through a zone of high energy produced thermally or by an electric discharge wherein gaseous silicon-and/or carbon-containing impurities are at least in part converted into radicals while the boron halide is unaffected, and then through a zone of lower energy wherein the radicals so formed recombine to form compounds having a molecular weight substantially higher and a volatility substantially lower than those of the original impurities, and condensing said higher molecular weight compounds from the gaseous boron halide.  The reducing gas may be hydrogen. In the apparatus of Fig. 1 (not shown) an A.C. voltage source produces a gas discharge across an annular space between two coaxial electrolyte-filled glass vessels, and the discharge produced radicals from the impurities in the gas-stream flowing in the annular space.  In the apparatus of Fig. 2 (not shown) a glow discharge is produced between two boron electrodes over which the gas stream is flowing at atmospheric pressure.  The boron halide may be mixed with a carrier gas e.g. hydrogen or a rare gas or, when the energy gradient is produced by a dark electric discharge, a hydrogen halide.

Abstract: 706,173. Television pick-up tubes. CATHODEON, Ltd. April 24, 1951 [March 2, 1950], No. 5378/50. Class 39(1) [Also in Groups XXXVI and XL(b)] A television signal-generating device comprises a first photo con ductive layer 3 of selenium or cad mium sulphide upon which the image is projected to cause the conductivity to vary from point-to point over the surface, a seconc photo conductive layer 5 which is rendered conducting point-by-point by means of a source of radiatior scanning the surface, and a pair of transparent aluminium electrodes 2, 4 connected to a circuit 12, 13 so that the process of scanning sets up a current in the circuit modulated in accordance with the point-by-point variation in the light intensity of the image. In the embodiment shown, the scanning is effected by means of an electron beam which impinges on a fluorescent screen 15 to produce a light spot which renders the photo conductive layer 5 conducting. An opaque layer 4 having high conductivity at right angles to the major surfaces but low conductivity parallel to the major surfaces, and made for example of soda-lime glass incorporating a suitable pigment, separates the two photo-conductive layers to prevent interference between the light of the image and scanning spot. By arranging the photo conductive layers to have different spectral response curves, the layer 4 may be omitted. In a further embodiment, Fig. 5 (not shown), the photo conductive layer 5 is replaced by a layer of material such as silica or magnesium fluoride which is rendered conducting by electron bombardment. The opaque layer is not necessary in this modification and may be omitted or replaced by a mosaic of mutually insulated conducting particles, e.g. silver globules.

[Also in Group XL (c)] In a narrow band telephony system the modulation 1 is transposed to a higher frequency band by a single sideband modulator 2, with carrier suppression, followed by a limiter 4. The constant amplitude frequency-modulated output may then be doubled in frequency at 5 to remove phase discontinuities of #, then divided in frequency in one or more successive stages, say by 2n and n<SP>1</SP>, by retroactive loops 6, 61 employing synchronized oscillators 14, 141 and frequency multipliers 17, 17<SP>1</SP> between the outputs of the oscillators and frequency reducing mixers 8, 8<SP>1</SP> to which the stage inputs are applied. The final constant amplitude signal, of bandwidth only, say, 30 c/s., may then be Class C amplified and radiated. At the receiver the frequency w/nn<SP>1</SP> may then be frequency multiplied by n and n<SP>1</SP> and transposed down again to the original audio frequency range. Absence of any amplitude variation in the receiver output does not wholly remove the intelligence. The single sideband amplitude modulator may be one employing phase-shifting networks for the audio modulation, so that two audio outputs in relative phase quadrature are applied to two R.F. amplifiers to which a carrier is supplied in phase quadrature, the R.F. outputs then being additively combined. The phase shift networks may each employ a phasesplitting triode with series and shunt R.C. circuits connected to their anode and cathode and to a common output having a further shunt R.C. circuit.
