Title: Improvements relating to glassy phosphate powder compositions and process of making the same
IPC: C02F5/08
Filed: 1947-02-28
Abstract: <PICT:0642944/III/1> <PICT:0642944/III/2> Phosphate glasses for domestic water softening, produced for example by heating dihydrogen mono-sodium orthophosphate and chilling to form a glass, having an alkali metal oxide to phosphorus pentoxide ratio of at least nine to ten, are rendered more easily soluble in water by forming as a coating on the surface of the finely-ground glass particles, the acid reversion product, viz. dihydrogen disodium pyrophosphate, by humidifying and heating, and incorporating in the coating, or mixing with the coated particles, a salt which in water will react with the acid reversion product to generate a gas, thereby dissociating the particles and speeding solution.  Such salts are sodium carbonate, bicarbonate, sulphite or bisulphite.  In a preferred embodiment the glass particles, ground to pass an 80-mesh sieve, mixed with about 5 parts of sodium carbonate and 5 of sodium bicarbonate, per 100 parts of phosphate, are fed into a rotating drum, the inner surface of which forms a frustrum of a cone.  The walls are formed by a series of louvres 9 (Fig. 2) through which at the inlet end of the drum through flue 25 air at a temperature of about 60 DEG  C. with a humidity of 90 per cent, hydrates and renders sticky the surface of the phosphate particles, which then pass to a drying zone where air at a temperature of 150 DEG  C. enters via flue 26, thereby partially removing the added moisture and reacting the remaining moisture with the glass to form the acid reversion product as a coating which also contains the adhering sodium carbonate and bicarbonate, on the surface of the particles. Alternatively the surface hydration may be effected by means of a hydrated salt or a 10 per cent solution of water in acetone, followed by heating to effect reversion. Specification 642,945 is referred to.ALSO:Phosphate glasses for domestic water softening are rendered more easily soluble by forming a coating on the surface of the finely ground particles of the acid reversion product of the glass, viz. dihydrogen disodium pyrophosphate, by humidifying and heating, and incorporating in the coating, or mixing with the coated particles, a substance which in water will react with the acid reversion product to generate a gas, thereby dissociating the particles and speeding solution.  The added substance may be sodium carbonate, bicarbonate sulphite or bisulphite.  The final product may be formed into flakes or agglomerates.  Specification 642,945 is referred to.

Abstract: 511,706. Weft-inserting and beat-up mechanism for narrow ware looms &c. SHIMWELL, O., and SHIMWELL, D. W. Feb. 26, 1938, Nos. 6149 and 9019. [Classes 142 (ii) and 142 (iii)] The shuttle a is moved in an arcuate path by levers j, k pivoted on a bracket m on a lever n, which is rocked about a pivot o by a link p and vertical slide q engaged by a block r on a crank pin s on a crank disc t on a shaft n. The link p is carried by a strut v. The levers j, k enter and leave slots b, c in the shuttle under the concrol of a cam groove y, the shuttle being always under positive control. The shuttle of the curved shape shown with tapered ends, an opening, and a cover is held in the shuttle boxes d, g by tops e<1>, f<1> which can be swung out of the way. The reed h may be stationary or be carried by a lever 12 operated by cam-controlled lever mechanism 10, 11 the lever 12 being pivoted to an arm 2 which carries the shuttle track and is rocked about a rod 13 by an eccentric 9. The reed and shuttle operating mechanism are thus moved back and forth. The weft is beaten up by a comb 14, Fig. 10, carried in slides in arms 15 oscillated by cam-controlled lever mechanism, the slides being vertically reciprocated by bell crank levers 20 a rod 22 and an eccentric 21. The reed carrying arms 12 may be connected to the arms 15 by springs 29 and links 28, so that the arms 12 may move back relatively to the arms 15 in case of a shuttle trap. The reed is stationary whilst the shuttle is passing through the shed. The comb carrying levers then go backwards to meet the advancing reed halfway, the comb rises to engage the weft and then moves forwards to beat it up. The warp threads pass under a rod 26 on brackets 25 attached to the arms 15, the rod 26 being thereby depressed to tension the warp threads when the comb is being raised, its correct entry between them being thus facilitated. The reed may comprise two rows h, h<1>, Fig. 12, of dents, staggered as shown, the teeth of the comb being of different lengths, so that the larger teeth may get behind any broken weft end lying against the front row of dents. According to the second Provisional Specification, the comb teeth may have a notch or groove near their ends. The warp threads may be tightened when shedding is occurring and when the comb enters the warp threads by rods in advance of one another and situated above and below the warp threads, both or the upper rod being moved forward and back. When a shuttle race is used, the comb may have a part of swan neck shape and the shuttle race and reed may have a downward movement as they move forwards. Specification 430,593 is referred to.
