Patent GB-571415-A (GB)
Title: Improvements relating to the preparation of cation-exchange materials
IPC: B01D15/04
Filed: 1944-02-04
Abstract: A method of improving the cation exchange properties of a granular material substantially insoluble in water and prepared by the action of a concentrated liquid sulphonating agent on an organic carbonisable material such as wood, lignite, peat and bituminous coal, comprises further sulphonating the material, while containing less than 18 per cent moisture, with sulphur trioxide gas.  The liquid sulphonating agents include concentrated or fuming sulphuric acid and chlorsulphonic acid.  In this way the high capacities characteristic of the sulphur trioxide treatment are combined with the hardness characteristic of the liquid sulphonating treatment. The resultant products are useful in the softening of water and in other cation-exchange processes. The products of the invention may be prepared by adding the concentrated liquid sulphonating agent to the raw material which is preferably more or less granular in form, at a temperature in the range of 60 DEG  to 100 DEG  C. with agitation. Generally, from 0.85 parts to 4 parts by weight of sulphonating agent for each part of raw material should be used, the reaction time preferably lasting for several hours.  The sulphonated material is then washed and dried or may first be converted to the sodium-exchanging condition by treatment with sodium carbonate solution.  The gaseous sulphonation may be applied to the relatively dry product in the hydrogen- or sodium-exchanging condition or while the product is charged with calcium or other exchangeable cations. The simplest method is to pass the gas up through a column of the granular product using the gas pressure as a means of agitating the granules.  The gas may be diluted with an inert gas such as air to avoid overheating; ratios of air to sulphur trioxide from 1 : 1 to 4 : 1 are satisfactory.  The second sulphonation is complete when the swelling of the granules ceases.  An example describes the treatment of granular bituminous coal with 20 per cent fuming sulphuric acid, giving a product which after washing and drying is treated with sulphur trioxide gas.

Abstract: 1357693 Cathode materials and processing RCA CORPORATION 18 Jan 1972 [18 Jan 1971] 2300/72 Heading H1D An electron emitter device is prepared by coating the emitting surface of a cathode with a protective material 32, placing the cathode in the device, continuously evacuating the device, baking the device at a first temperature and heating the cathode to a higher temperature to evaporate or decompose the protective layer whilst maintaining the envelope of the device at a temperature below the first temperature. The coating prevents contamination of the cathode by gases released from the envelope. A photomultiplier 10 comprises an opaque photocathode 12, a heater 24, dynodes 16, field electrodes 18, an anode 20 and sources of Ce and O (not shown) within a glass envelope 14. The cathode comprises an epitaxial GaAs layer 28 on a GaAs substrate 26 coated with a protective layer 32 of KCl. Whilst the envelope is continuously evacuated the tube is baked at 350 C., cooled, the cathode heated to 500 C. by the heater 24 to evaporate the KCl and the cathode activated with K, Ce or Na and O or F. With InSb cathodes the protective layer is CsI which is evaporated at 400 C., the tube being baked at 300 C. The protective layer is formed in another evacuated chamber preferably during cathode manufacture in rarified He by heating for 1 minute to 650 C., cooling and evaporating a KCl bead; Se cathodes are first cleaned by electron bombardment. The protective layer may be NaCl and RbCl. Cathodes may be semi-transparent photocathodes or dynodes, may be formed on the envelope and may be of GaP, InGaAs, Si, W or MgO.
