The production of suitable ion-exchange substances is described in Specification 450,574, [Group I].  The substances are regenerated by treatment with acid or salt solutions.  The method of obtaining a solution of sodium chloride from one of sodium sulphate is described by way of example. The sulphate solution is passed through the exchange material, sodium ions being retained. On regeneration of the material with hydrochloric acid, the effluent liquid is a solution of sodium chloride.ALSO:Ion-exchange substances obtained by treating wood or naturally-occurring decomposition products of vegetable matter with sulphuric acid, sulphur trioxide or chlor-sulphonic acid are used for treating water or converting aqueous salt solutions into solutions of acids, or obtaining a solution of the salt of one acid from a solution of the corresponding salt of another acid. The production of suitable ion-exchange substances is described in Specification 450,574.  The substances are regenerated by treatment with acid or salt solutions.  Water which has been treated with one of these substances having an acid reaction may be further treated with a base-exchange material having an alkaline reaction after carbonic acid has been driven off by heating or it may be treated with baryta or other reagent to remove the sulphuric and hydrochloric acids.  A water containing sulphate may be obtained by bringing the water into contact with one of the carbonaceous substances having an acid reaction removing carbonic acid by heat treatment, precipitating hydrochloric acid as insoluble chloride and adding alkali or alkaline salt to react with the sulphuric acid to form a soluble sulphate.  Or the water after treatment with the carbonaceous substance may be caused to flow quickly over marble or other alkaline earth carbonate, such as dolomite or magnesite.  Neutral water may be obtained by mixing water which has been passed through carbonaceous material having an acid reaction with water containing carbonates, produced by passage through ordinary zeolites or otherwise.  The method of obtaining a solution of sodium chloride from one of sodium sulphate is described by way of example of the use of the materials.

Abstract: 1,125,731. Photographic cameras. AGFA-GEVAERT A. G. March 16, 1966 [March 27, 1965], No. 11534/66. Headings G2A and G2E. A cine or photographic camera receives a cassette 6 whereon the presence or absence of an aperture 7 is indicative of two different type of film such as daylight film and artificial light colour film of the same sensitivity, the aperture being sensed by feeler 12 of a spring-loaded slider 9 which may adopt three stable positions and may actuate mechanism which moves a conversion filter 19 into or out of the path of objective 1, whereby the artificial light film may be used as a daylight film of lower sensitivity. Slider 9 has control cams 9b, 9c which may respectively displace the filter 19 into its operative position, and raise a catch 15 to engage and retain spring 33 on spring-loaded pivoting lever 21. Lever 21 engages slider 9 through pin and slot 30. 9e, and may occupy two positions T, K for daylight or artificial light respectively in which vanes 29 or 37 are swung into sight of the viewer 2, 5. When a cassette containing artificial light film and having an aperture 7 is pushed into the direction 32 into the camera, slider 9 is able to move to the right a distance "a" and filter 19 is moved in front of lens 1 and honeycomb lens 3 of the photo-cell 4. Cam 9a is "a/2" in width and is therefore not displaced and the film may be exposed as daylight film of reduced sensitivity. For artificial light use, lever 21 is set to the K position when pin 30 displaces slider 9 by amount "a/2" into a third position; the filter is thus retracted, and catch 15 is raised to retain lever 21 in the artificial light position against spring 22.
