Filed: 1972-02-15
Abstract: 1415512 Gas detectors ELECTRICAL REMOTE CONTROL CO Ltd 8 Feb 1973 [15 Feb 1972 26 July 1972] 7035/72 Heading G1N In a catalytic detector means are provided to continuously supply a mixture of air and combustible gas or vapour of known composition to the vicinity of the catalyst whereby, in use, the combustible gas or vapour is detected to provide a constant positive background indication, malfunction of the detector, e.g. caused by the catalyst becoming inactive, being observed as a reduction in the positive indication. As described, the detector includes a temperature dependent resistance made of platinum which also acts as the catalyst. The mixture of known composition may be provided by a substance which emits gas or vapour by evaporation or chemical decomposition. Alternatively, such mixture is supplied from a gas cylinder. When the gas is emitted by evaporation, the composition is known from the ambient temperature and the vapour pressure of the substance at that temperature. Suitable examples of substances are given. Temperature compensation may be provided or the detector may be mounted on a thermostat. Temperature compensation may be achieved by adjusting the alarm level of a bridge in which the catalytic resistor is arranged. Alternatively a calibration chart may be used to reset the zero. Also, pressure variations detected by a transducer in the wall of a vessel containing a liquid having substantially the same coefficient of vapour pressure as the emitting substance may be used to compensate for temperature variations. The substance may be contained in a vessel and is supplied to the catalyst via a wick. In a preferred embodiment, the mixture is provided by evaporation of a solvent containing an excess amount of solute. Suitable examples are given. Liquid solvent and solid solute, two partially miscible liquids or two solids may be used. The solvent or solute may be multicomponent. Where liquid is used, it may be contained in an inert porous support, e.g. a bed of porous granules. The detector may be used to detect methane in mines, petrol vapour on car ferries, flammable gases on oil tankers or in chemical plants, or to test for town or natural gas leaks.

Abstract: 731,107. Electrolysis of potassium and sodium chlorides solution. NIAGARA ALKALI CO. March 16, 1953 [April 8, 1952], No. 7196/53. Class 41. A process of preparing caustic alkali, chlorine, hydrogen, and potassium chloride comprises electrolysing an aqueous solution of sodium chloride and potassium chloride to obtain a catholyte containing water and Na+, K+, OH - and Cl - ions, and concentrating said catholyte to precipitate potassium chloride. The solution may be prepared from an ore such as Sylvenite comprising sodium and potassium chlorides. After electrolysis the catholyte may be evaporated in stages, the K+ and Cl - ions combining and precipitating as potassium chloride to leave a solution comprising mainly sodium hydroxide. The proportions of NaCl and KCl may be such that all the chloride is separated as KCI; when the proportion of NaCl in the original solution is increased the chloride first precipitated is KCl, but further concentration precipitates a mixture of KCl and NaCl; when the proportion of KCl in the solution is increased, all the recoverable chloride is precipitated as KCl, and excess potassium remains as caustic potash.
