Title: Improvements in the preparation of crystallized alkali metal metasilicate hydrates
IPC: C01B33/32
Filed: 1952-12-09
Abstract: Crystallized alkali metal metasilicate hydrate is prepared by allowing an unboiled melt thereof to solidify in the presence of not more than 5 per cent and preferably not less than 1 per cent of a water-insoluble silicate, preferably of a divalent metal. The alkali metal metasilicate may be prepared by melting soda and silicic acid in the desired ratio or by melting technical sodium silicate, dissolving it in a quantity of water equal to the water of crystallization of the desired hydrate and adjusting the alkali metal oxide to silicon dioxide ratio to 1 by addition solution which may be regarded as a melt of the hydrate, is added the water-insoluble silicate, preferably that of magnesium or aluminium, in the form of a paste or dry powder, or alternatively they may be formed in situ by the addition of a soluble salt of the metal to the alkali metal metasilicate melt whilst stirring. The resulting melts cool to form a grindable solid mass. According to examples (i) water glass is stirred and gently heated with caustic soda in the presence of a magnesium silicate paste. After cooling to 36 DEG  C. the melt solidifies and may be ground after storage for 1 to 2 days to form a dry sodium metasilicate-9-hydrate powder.  The pentahydrate may be similarly prepared.  (iii) Sodium silicate of a Na2O : SiO2 ratio of 1 : 2.05 is treated with soda lye and moist aluminium silicate is stirred in.  After cooling and storing for 2 1/2 days the sodium metasilicate-5-hydrate may be ground.

Abstract: 735,894. Automatic mixing control systems. PERMUTIT CO., Ltd. Dec. 2, 1953 [Dec. 9, 1962], No. 31192/52. Class 38 (4). Water from a main 1 is passed through a container 5 containing hydrogen-ion-exchange material and blended with water from the same main which has been passed through sodiumion-exchange material in a container 4. The proportion of the components of the blend is controlled by a valve or valves 6 so as to produce a water supply through a conduit 10 which is slightly acid or alkaline. To maintain constant alkalinity or acidity of the blend, conductivity cells 12 and 14, associated with the blended water and the acidified component respectively, are arranged in a bridge-controlled relay circuit 15 controlling a reversible motor 9 which operates valve 6 to maintain a constant ratio between the two conductivities. The sense of motor operation is chosen to suit an alkaline or acid blend and to guard against incorrect operation if the state of the blend should change accidentally, change in colour of an indicator added from a vessel 24 to blended water is detected by a photo-cell 22 which operates a relay 25 to reverse motor 9 until the initial state is restored. A further container 26 of hydrogen-ion-exchange material prevents errors when container 5 is nearing exhaustion. Conductivity cells 28 and 30 are associated with the acidified component and arranged in a bridge circuit to detect exhaustion of and/or initiate regeneration of container 5 as in Specification 624,884, [Group I].
