Title: Improvements in or relating to moulds for casting of metals
IPC: B22C9/04
Filed: 1945-10-30
Abstract: 622,459. Moulding processes. SHAW, N. Oct. 30, 1945, No. 28792. [Class 83 (i)] In making moulds for casting metals and alloys, the pattern is invested, one part at a time, with a non- refractory liquid material which will set hard without much change of volume, each mould part being allowed to set and having its parting surfaces treated with wax solution &c., to prevent wetting, before the next part is invested. These mould sections are reproduced in refractory mould material for the casting moulds. These reproductions may be made by removing one mould section from the invested pattern, filling the space so left with refractory mould material, allowing this to set, removing another section, waxing the interface, filling the space so left with refractory mould material and so on, repeating for each section. Preferably two mould sections A, B, Fig. 2, are made from an oversize pattern R in dental plaster and holes P and then gate recesses F, Fig. 3, are cut therein. From each section A, B, after closing the holes P with clay, a master section C, D, Fig. 4, with the pattern in relief, is formed in hard dental plaster or cast metal and holes K are cut at the ends of the ribs Fl formed by the recesses F. The master sections C, D are then assembled with plaster walls E, Fig. 6, and a rod L through the holes K and the space G is filled in with a slurry of refractory mix. A number of parts G, so made, are assembled, with end members H, J, Fig. 8, made with one flat face, to form a multiple mould, the holes K being aligned to form the runner. Mould materials. For the first investment, dental plaster sold under the trade name " Kalestone " may be used which expands on setting about 0.04 per cent. For the refractory reproductions a suitable material is sillimanite bonded with partially hydrolysed silicone ester as described in Specification 575,752, [Group IV], and this has a contraction on setting of 0.07 per cent. The inner surface of the refractory moulds may be case-hardened, polished, or coated with graphite or chrome films or with metallic powders or may have tungsten carbide or other inserts attached thereto. The original pattern may be made of wood, metal, or plastic, and should be oversize to correspond to the shrinkage of the metal cast. Specification 575,734 also is referred to.

Patent GB-423262-A (GB)
Title: A process for the recovery of phosphorus from gases
IPC: C01B25/02
Filed: 1933-10-20
Abstract: <PICT:0423262/III/1> Phosphorus is recovered from gases, e.g. blast-furnace gases containing the same in considerable dilution by subjecting the gases to a dust-removing treatment wherein they are cooled to a temperature above the dew point of phosphorus, e.g. 150 to 300 DEG  C. The gases are then subjected to the action of aqueous cooling agents containing an electrolyte, e.g. hydrofluosilicic or phosphoric acid or their salts.  The hydrofluosilicic acid is produced by the action of water on silicotetrafluoride produced during the formation of the phosphorus from calcium fluoride present in the material treated.  As shown, blast furnace gases containing phosphorus vapour are passed through a dust removing chamber 1, then through one or more of three centrifugal coolers and dust separators 2 and thence, at a temperature of 150 to 200 DEG  C., to a condenser 8 where treatment is effected with a spray of water circulated by a pump 14.  Liquid phosphorus 11 collects in the base 10 of the condenser and may be withdrawn by a valve 38. The gases, at about 65 DEG  C., pass by a pipe 17 to a second condenser 18, cooling water being delivered by a pump 26 to spray 19; a vacuum cooler 24 is included in the circulating system to keep the water at about 36 DEG C.  Condensed phosphorus 21 is conveyed to the receiver 10 by a pump 36.  From the condenser 18 the gases pass to a third condenser 28 where they are sprayed with cold water, the gases passing off by a pipe 30 and the phosphorus sludge 32 being conveyed by a pump 35 to the receiver 22 of the second condenser.
