Title: Improvements in or relating to electric discharge tubes
IPC: H01J61/28
Filed: 1937-05-18
Abstract: 472,307. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 18, 1937, Nos. 13882 and 13883. Convention dates, May 18, 1936 and June 6, 1936. [Class 39 (i)] A metallic-vapour discharge tube, e.g. a high-pressure tube 1, comprises an auxiliary chamber 2 filled with gas and a liquid which is in contact with the coldest part of the wall of the discharge chamber wherein the auxiliary chamber is formed in such manner that vapour condenses on a portion of the wall thereof which does not form part of the wall of the discharge chamber and the condensate can flow back to the liquid. A highpressure lamp has a cylindrical quartz vessel and a filling of mercury, some of which is not evaporated during operation. Argon at 5 mms. is added. Electrodes 7, 8 heated by the discharge or by independent means are supported on conductors housed in insulating tubes. The cap 13 is mounted on an extension 12 of the vessel. The auxiliary chamber 2 is filled with mercury 5 and argon at 20 cms. and is provided with a tube 6 projecting into the mercury or stones or pieces of tungsten to facilitate boiling. A quartz screen 15 protects the partition from the discharge and condensate is retained above the screen by a collar 17 formed about an aperture in the screen. Thin metal wires preferably in the form of a clew may be provided between the partition 3 and the screen 15 to retain the mercury. The temperature at which the liquid boils in the vessel 2, and hence the vapour pressure in the discharge chamber, may be adjusted by regulating the gas pressure in the chamber 2. The electrode 7 may be further supported by helical tungsten wires 18. Thermal radiation from the upper end is minimized by a platinum layer 19. The liquid in the chamber 2 may be mercury, benzyl benzoate or cethylic - alcohol. The cylindrical or conical vessel 2 is preferably inclined at an angle of 25 to 65 to the produced axis of the discharge chamber so that the liquid in the chamber 2 covers the partition 3 when the lamp is in both the horizontal and the vertical positions. The lamp may be used for the production of ultra-violet rays and is then surrounded by a filter 20 from which the chamber 2 projects wholly or partly. An external screen at right-angles to the axis of the lamp may be provided to prevent the external conduction of heat from the discharge chamber to the chamber 2. In a further form, the partition is formed by a cylindrical hollow tungsten body 22, Fig. 4, provided with an aperture 23. A thermal radiator comprising metal straps 27 and adjustable fins 28 is provided on the chamber 2 in such manner that the capacity of that part of the chamber between the straps and the liquid is less than that of the rest of the chamber. In other forms a bowl-shaped tungsten screen 29, Fig. 6, is secured to a tungsten rod which is sealed into the partition and projects into the liquid 5, or a rim 31, Fig. 7, may be provided on the partition to impede the flow of condensed mercury.

Patent GB-639855-A (GB)
Title: Improvements relating to processes for the manufacture of alkali metal hydroxides, sulphur dioxide and sulphuric acid
IPC: C01B17/52
Filed: 1947-05-23
Abstract: Alkali metal hydroxides, e.g. NaOH, KOH and LiOH, and sulphur dioxide are made by reacting a metallate (i.e. the chemical combination derived from the hydroxide of a polyvalent metal, which forms an insoluble sulphide in alkaline solution, in which one or more hydrogen atoms are replaced by an alkali metal) with an alkali metal sulphide, to form an alkali metal hydroxide and a sulphide of the metal of the metallate, and separating and roasting the metal sulphide to form sulphur dioxide and the metal oxide, which may be used together with alkali metal hydroxide thus produced to form the metallate.  Metals specified are zinc, copper, lead, nickel, tin, iron and manganese.  The alkali sulphide may be made by reducing with coal or coke an alkali sulphate which may contain the metal of the metallate as impurity or may be purified by crystallization prior to the reduction.  The metallate may be formed by dissolving the metal oxide or hydroxide in aqueous caustic alkali solution.  In the case of the zincate, purification may be effected by adding alkali sulphide in stoichiometrical amount to precipitate impurities as sulphides, and after removal of impurities further alkali sulphide may be added to precipitate zinc sulphide.  The caustic alkali formed may contain some alkali sulphide by adding excess of the latter to the metallate.  In a modification, alkali sulphide is reacted with a metal capable of forming a metallate or an oxide or hydroxide thereof and water.
