Title: Improvements relating to the preparation of chloride
IPC: A23B7/022
Filed: 1942-03-16
Abstract: 561,936. Chlorides. OCEAN SALTS (PRODUCTS), Ltd., and ADAMS, B. A. March 16, 1942, No. 3427. [Classes 1 (ii) and 1 (iii)] The chlorides of elements, the bases or basic salts of which are soluble in hydrochloric acid, are prepared by the combination of steps comprising contacting a solution containing chlorine ions with a cation exchange material having exchangeable hydrogen ions to form a solution of hydrochloric acid, adsorbing the chlorine ions on an acid adsorbing material and contacting the acid-charged material with a solution or suspension of the base or basic salt to yield a solution of the chloride. The method is employed for recovering chlorides from dilute solutions, e.g. sea water or washes from chemical processes, e.g. weak sodium, ammonium, calcium, magnesium solutions. Example 1.-Sea water from which sulphate ions had been extracted was passed through an organic cation exchange material which had been treated with an acid so as to have hydrogen ions available, the total effluent resulting having a proportion of free hydrochloric acid was passed through an acid-adsorbing material (meta-phenylene diamine resin) which adsorbed the chlorine ions. A hot solution of barium hydroxide containing some suspended carbonate was passed through the hydrochloric acid saturated bed to yield an effluent containing barium chloride. Example 2.-A bed of hydrochloric acidcharged material, prepared according to Example 1, was treated with a suspension of magnesium basic carbonate containing hydroxide to give a solution of magnesium chloride. Further concentration may be effected by adding more basic material to the chloride solution and passing it again through the acid charged bed.

IPC: G03F7/20
Filed: 1972-01-28
Abstract: 1381082 Making patterns with light beams GERBER SCIENTIFIC INSTRUMENT CO 28 Jan 1972 [23 April 1971] 4159/72 Heading G2A [Also in Division B6] A graphic design is produced by selectively exposing a photo-sensitive surface M to a cathode ray tube 12 using a projection lens system 14, the face of the CRT 12 being divided into a central area 59 in which the cathode ray beam is used to draw characters, and an outer annular portion covered by an opaque mask 60 including a plurality of openings 61 (a - e). When the beam is deflected to impinge on one such opening continuously, it may scan the opening by being deflected in a raster fashion, or alternatively it may be defocused to form a spot larger than the opening. After one character has been generated and projected on to the surface M, the CRT 12 and lens system 14 are moved in accordance with control signals from a computer 18, which also controls the beam generated within the CRT 12. The mask 60 may be replaced, at each sub-area of the screen associated with a particular character, by phosphorescent material in the shape of the character. Alternatively a movable mask may be used. The device may also be used to draw lines by means of a spot of light which is moved over the surface M. The beam current control 50 is provided with compensating networks to increase the beam intensity as a function of the rate at which the projected image is moved over the surface, which thus receives the same quantity of light per unit time.
