[Class 39 (i).] A metallic-vapour arc lamp, working on alternating current, is provided with electrodes 4, 5 of substantial mass and of refractory metal, e.g. tungsten, tantalum, molybdenum or niobium, between which the discharge passes when the. lamp is working under high pressure. For starting, when the lamp is in the lowpressure condition, incandescent electrodes, which may be in the form of spirals 2, 3, 3a of tungsten wire, are provided. The construction shown on the left side of the Figure is suitable for the employment of difficultly vaporizable metals solid at ordinary temperatures, e.g. cadmium or zinc, and comprises a metal case 12, with a condensed deposit 23 of the vaporizable metal, surrounding a pair of spirals 2, 3, which at starting can be raised to incandescence by current from the mains 24, 25. The part of the lamp surrounding the incandescent electrodes is provided with a heat-insulating layer 15 surrounded by a metallic shell 16. The construction shown on the right side of the Figure is suitable for the employment of mercury as the vaporizable metal, and comprises an annular shoulder 18 for the reception of the mercury. To start the lamp, the switch 27 is first closed in order to supply heating current to the spirals at each end of the tube ; the switch is then opened, whereupon an arc passes between the incandescent electrodes and subsequently jumps over to the main electrodes 4, 5, whereupon the incandescent electrodes become part of the heating resistance of the lamp, the two spirals 2, 3 in the left-hand construction being placed in parallel by closing the switch 32.

Abstract: 358,984. Electric signalling systems. ASSOCIATED TELEPHONE & TELEGRAPH CO., 1033, West Van Buren Street, Chicago, U.S.A. July 9, 1930, No. 22632/31. Convention date, July 15, 1929. Divided on 358,889. Drawings to Specification. [Class 40 (i).] Relates to an electric signalling system for transmitting information regarding the selling price of various stocks so that such prices may be indicated at a plurality of receiving points. The system is identical with that described in Specification 358,889, wherein the stocks are listed by means of one, two or three letters under the control of letter keys which when operated in accordance with a particular stock operate registers and a translator comprising a cross-connecting frame to effect the translation of the stock letters into a three-digit code. The price and nature of the quotation are recorded on further registers and impulsing equipment is successively associated with all the registers to effect the transmission of impulses indicative of the registered quotation. Each digit transmitted to the receivers constitutes four impulses of alternate polarity, the strength of the impulses depending upon the setting of the registers. The claims however relate more particularly to the display arrangements at the receiver. The transmitted impulses operate registers at the receiver in accordance with the stock, price and nature of quotation, the stock registers effecting selection of the appropriate set the indicators which are operated in accordance with the setting of the price register. Specifications 15072/12, [Class 40 (iii), Telegraphs, Electric], and 358,924, also are referred to.

Abstract: 1,144,345. Radio position finding. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 16 May, 1966 [28 May, 1965], No. 22713/65. Heading H4D. The position of a material interface, e.g. that between the atmosphere and a column of water, is determined by immersing a transmission line 4 in the material, of such a type that the material becomes the dielectric of the line, and an impedance discontinuity appears at the interface. As shown the line is an airspaced coaxial cable, holes allowing the material to pass into its interior. Thus by passing a pulse down the line, the interface reveals itself by a reflection, the depth of the interface being given by the time lapse between the transmission of the pulse and its echo. The echo is displayed on an A-type C.R.T. The transmission line may, alternatively, comprise two parallel wires, or the outer conductor of the line, when coaxial, may be the metal container of the material.

Patent GB-728504-A (GB)
Title: Improvements in or relating to the production of surface active agents
Filed: 1951-10-04
Abstract: Surface-active salts of aryl-substituted alkyl hydrogen sulphates are prepared by reacting an aryl-substituted alkyl hydroperoxide, wherein the alkyl group contains at least 4 carbon atoms and in which the hydroperoxide group is attached to a carbon atom not directly attached to the aromatic nucleus, with sulphur dioxide or a salt of sulphurous acid whereby a product containing an aryl-substituted alkyl hydrogen sulphate is formed and converting this sulphate to a salt by reaction with an inorganic or organic base.  In a modification, the hydroperoxide is reacted with sulphur dioxide or a salt of sulphurous acid in the presence of the base and an aqueous and/or alcoholic medium whereby the desired salt is obtained directly.  Reaction with sulphur dioxide may be effected at temperatures up to about 100 DEG  C.; the sulphur dioxide may be used in gaseous or liquid phase and at normal, reduced or elevated pressure.  Specified salts of sulphurous acid are sodium bisulphite and ketone-bisulphite addition compounds, e.g. solid acetone-sodium bisulphite.  Suitable bases are alkali-metal hydroxides, ammonia, pyridine, morpholine and alkanolamines, e.g. the ethanolamines and butanolamines.  The hydroperoxides may be prepared by oxidation of aromatic-substituted aliphatic hydrocarbons having a quaternary carbon atom adjacent the ring and at least 4 carbon atoms in the alkyl group.  Metal-containing oxidation catalysts, organic peroxides, e.g. tert.-butyl hydroperoxide or a portion of a previous oxidation batch may be added to aid oxidation. Preferably less than 25 per cent of the hydrocarbon is oxidized. The product may be refined prior to the sulphation.  Thus, unreacted hydrocarbon may be distilled off or the oxidate may be extracted with a polar solvent to extract the hydroperoxides, the solvent thereafter being removed, if desired.  In another method, the oxidate is treated with alkali; a small amount serves to remove carboxylic acid impurities and larger amounts may be used to extract also the hydroperoxides, simultaneously or subsequently.  The hydrocarbon feed-stock may be prepared by alkylation of aromatic hydrocarbons such as benzene, toluene, xylenes, naphthalene, diphenyl and anthracene with olefines such as cracked wax olefines, copolymers or polymers of propylene, butylenes and amylenes and olefines obtained by Fischer-Tropsch type syntheses.  If detergent products are desired, the alkyl substituent should contain 8-16 carbon atoms.  In an example, nonyl-toluene is air-blown at 140-150 DEG  C. yielding an oxidate containing 4.55 per cent hydroperoxides which is mixed with water, treated with gaseous sulphur dioxide and then neutralised with alkali.  Specifications 685,621 and 695,547 are referred to.
