A projection lamp comprises an envelope 2 having a number of lead-in wires sealed into the base, a filament 28 connected to two of the lead-in wires, a reflector 20 mounted within the envelope to reflect light from the filament and a probe 50 mounted on one of the lead-in wires to extend parallel to and close to the filament and connected by way of a high resistance to an external terminal between which and the filament a voltage source is connected in use. The effect of the probe is to reduce blackening of the bulb. The reflector 20 has a central aperture in which is fitted a ceramic plug 22 carrying filament support wires 24, 26 and being secured in places by wedges. A steel spring clip fits over the rear of the plug 22 and carries at the lower part a U-brace 48 to which struts 44, 46 are attached, the other end of the struts being secured to lead-in wires 16, 17. The filament 28 extends between the supports 24, 26 and a ballast filament 30 from the support 26 to a rod 32 connected to the lead-in wire 14 (not shown). A fuse in a glass sleeve connects one lead-in wire to the support 24. The lead-in wire 16 also carries a probe 50 of molybdenum wire parallel to and a few millimetres from the filaments 28, 30 and connected to a resistance formed by a thin line of graphite painted on the header between the lead-in wires 14, 16.

Abstract: 1170929 Antiviral substance GLAXO LABORATORIES Ltd 16 Dec 1966 [28 Dec 1965], 54972/65 Heading C2A [Also in Division A5] The invention relates to an antiviral nucleic acid substance, isolated from the cells of Penicillium ckrysogenum, and being soluble in 2M aqueous sodium chloride containing 9% (v/v) ethanol but insoluble in 2M aqueous sodium chloride containing 20% (v/v) ethanol, possessing an absorption maximum at about 259 mÁ and being active against both DNA and RNA viruses, being unaffected by trypsin and deoxyribonuclease and only slowly inactivated by ribonuclease, i.e. it is a double stranded ribonucleic acid. A pure specimen has a molecular weight of 200, 000 or greater. The substance is obtained by the surface or submerged culture of Penicillium chrysogenum, e.g. Thom strain ATCC 10,002 in a nutrient medium, followed by the separation of the cultured cells from the broth, rupture of the cells and fractionation of the cell contents. The separated cells, preferably in the form of an acetone powder, are ruptured by mechanical means, freezing and thawing or by treatment with an aqueous wetting agent, e.g. sodium lauryl sulphate. Proteins may be removed from the cell contents by the addition of a protein precipitant such as a water-soluble hydroxy-benzene (e.g. phenol) or a long chain anionic wetting agent preferably in the presence of an electrolyte. Polysaccharides may be removed by distribution between a concentrated aqueous solution of an electrolyte and an alkanol immiscible therewith (e.g. phosphate buffer #H 7.7 and 2-methoxyethanol), whereby polysaccharides are retained in the alkanol phase while the desired nucleic acid is retained in the aqueous phase. A final purification may be obtained by (a) precipitation of the active substance by the addition of a watermiscible organic solvent; (b) gel filtration on a cross-linked dextran fractionating material of molecular weight 5000 or greater. The antiviral nucleic acid is incorporated in pharmaceutical compositions (see Division A5).

Title: Improvements in or relating to methods of producing coatings on substrates
IPC: H01B1/00
Filed: 1965-12-28
Abstract: Coatings of metals, metal oxides and metal compounds may be deposited on a substrate by feeding a liquid material, which comprises a metal salt solution or an organo metallic compound, through a capillary tube, the solution or compounds being capable of pyrolysis, dripping the liquid into a heated zone provided in the reaction tube so as to form a gaseous material, and leading the gas to a reaction zone of said tube and pyrolysing the gas so as to deposit a desired product on a substrate present in the reaction zone, the gases being allowed to mix prior to entering the reaction zone when more than one liquid starting material is introduced into the heating zone.  A carrier gas, which may be air so as to achieve a desired oxidation, may be introduced into the tube independently of the liquid material.  The production of layers of tin oxide or mixed tin antimony oxides using SnCl4 solution, a mixed solution of SnCl4 and SbCl3 or [Sn(C4H9)4] and [Sb(C3H7)3] using air as a carrier gas are exemplified.

Abstract: 1359677 Condensing metal vapours ISC SMELTING Ltd 10 Nov 1972 [29 Nov 1971] 55291/71 Heading C7D [Also in Division F4] A method and apparatus for condensing, zinc vapour or cadmium vapour, in which the vapour is passed through a spray of molten lead droplets produced by the mutual impingement of at least two continuous streams of molten lead at a temperature between 430 and 650C. As shown the apparatus comprises a vessel 1 divided into upper and lower chambers 1a and 1b. Spray units each consisting of pairs of converging jets in the form of holes or tubes 4, preferably angled at 30 degrees to the horizontal, are provided in the roof of the chamber 1b. The upper chamber 1a is divided into Sections I, II, III by vertical partitions 2, 3. The molten lead in adjacent sections may be arranged to be at different temperatures. Baffles 5 and 6 in the lower chamber 1b constrain the vapour stream to follow a tortuous path. The molten lead, which contains condensed metal, e.g. zinc, and collects on the floor of chamber 1b, is passed into a device wherein the zinc is separated from the lead, the separated lead being pumped back into the chamber 1a for reuse. The condenser apparatus 13 may be located in the cross over duct 10 connecting the upper part of the shaft 11 of a zinc smelting blast furnace with a conventional lead-splash condenser 12 wherein sprays of molten lead droplets are formed by rotation of immersed impellers 15. Zinc vapour present in the offtake gas is thus condensed out.

Abstract: 1,165,548. Jet propulsion nozzles; exhaust silencers. SOC. BERTIN & CIE. Dec.9, 1966 [Dec. 13, 19651, No. 55352/66. Headings F1B and F1J. The invention relates to a gas discharge system which is effective to reduce the noise of the gas discharge, the invention being described with reference to a jet propulsion nozzle although it may also be applied to a silencer device used during ground running of jet engines. The nozzle shown in Fig. 1 is of convergent-divergent form, the convergent portion 2 being formed with longitudinally-extending corrugations 7 by means of pairs of substantially radially-extending walls 6. The corrugated nozzle portion thus provides spaced passages 8 for flow of exhaust gases and spaced passages 7 for inflow of ambient air. The divergent portion of the nozzle comprises a ring member 19 within which are disposed a series of circumferentially spaced members formed by pairs of substantially radial walls 20, the members formed by the walls 20 being disposed in alignment with the air inflow passages 7 of the convergent nozzle portion. The object of the invention is to ensure that the air flowing in through the passages 7 is mixed with the combustion gases flowing through the passages 8. The discharge area of the combustion gas passages 8 may be variable by means of flap members 12 pivotally mounted at 13 to the outer circumferential wall portions of the convergent portion 2, Fig. 9. The members 20 of the divergent portion are in the form of tetrahedrons 22, Fig. 10. and are secured to the outlets of the air inflow passages 7 by means of lugs 23. The members 20 may be formed with a portion 24, Fig. 11 which extends into the air inflow passage 7. In further embodiments for example as shown in Figs. 17 and 18 the members 20 are pivotally mounted at 28 and may be swung forwardly into the air inlet passages 7 of the convergent portion. The member 20 shown in Figs. 17 and 18 is formed with a passage 30 for air flow. In a further embodiment Fig. 20 the member 20 is formed with lateral walls 38 which may be moved about radial axes so as to vary the convergence of the members. In Fig. 24 a thrust reverser device 43, 44 is provided in the jet pipe upstream of the convergent-divergent nozzle portion, the divergent portion of the latter being provided with nozzle members 29 which may be moved between the extended position shown at the upper half of the Figure and the retracted portion shown at the lower part of the Figure. The embodiment of Fig. 26 (not shown) also incorporates a thrust reverser device.
