Patent GB-492963-A (GB)
Title: Improvements in metal, asbestos-cement and similar sheets and in the method of affixing them in position
IPC: E04D3/36
Filed: 1937-03-24
Abstract: 492,963. Sheet - roofing and like coverings. ROTHWELL, W. E. March 24, 1937, No. 8599. [Classes 20 (ii), 20 (iv), and 87 (i)] The adjacent edges of metal, asbestos-cement or like roofing and wall sheets are inclined to the general plane of the sheets and fitted with a joint-cover strip, and each of the fixing-bolts for the sheets carries a clamping-plate, the sides of which are inclined similarly to the inclination of the edges of the sheets and, when the bolt is in its fixing position, effect a wedging action between the sides of the cover strip and the edges of the sheet. The cover strip may be formed separate from the sheets, or it may be formed integrally with one or both sheets at the joint. The sheet shown in Fig. 7 is provided with inclined flanges f along its side edges, and with two or more intermediate corrugations f<1> having their sides inclined similarly to the flanges f. Each sheet is preferably slightly tapered from end to end, and the corrugations f<1> are correspondingly tapered to allow interfitting of adjacent sheets end to end. The sheets are jointed side by side by the cover strips G having inclined flanges g which fit over the edge flanges f; the strips G are tapered to correspond with the taper of the sheets. The sheet may be modified by forming an integral cover strip G at one edge, as shown in Fig. 8, or at both edges, and in these cases a separate cover strip is unnecessary ; the intermediate corrugations f<1> may be dispensed with, and, if desired, replaced by a single rounded corrugation. The fixing-bolt H is shown in Figs. 12 and 13 with the clamping-plate H<1> having inclined sides h disposed in engagement with the intermediate corrugations f<1> of two overlapping sheets ; this arrangement is additional to the use of the bolts and clamping-plates at the side joint edges. The clamping-plate is shown in Figs. 12 and 13 with the inclined portions h of two different widths so as to engage the corrugations of both sheets at the joint. The bolt H passes through either an angle-iron j, which is fitted to a metal purlin J, or the head of a screw which enters a wooden purlin. The sheets shown in Fig. 18 are of corrugated form, and the cover strip comprises a corrugated under member G4 which fits over the edges of adjacent sheets and is cemented to an upper member G. The bolt H engages in a slot g<4> in the member G<4> and is fitted with the clamping-plate H<1>. The Provisional Specification describes also the formation of an integral cover strip on one or both sheets at the joint with one side only disposed at an acute angle to the sheet, and, instead of using a separate clamping-plate on the bolt, the head of the bolt is provided with inclined sides to effect the desired wedging action at the joint.

Patent GB-828909-A (GB)
Title: Steaming and pulping fibrous material
IPC: D21C3/24
Filed: 1956-03-20
Abstract: <PICT:0828909/IV (a)/1> Wood chips and like fibrous materials are subjected in a pressure vessel to treatment with steam under pressure in the absence of air, whereafter the pressure is reduced, but not completely released, and the material is treated with a cooking liquor and then discharged from the vessel, a superatmospheric pressure being maintained throughout the process.  As shown, during the charging of fibrous material, e.g. wood chips, to the pressure vessel, valves 24, 27 are open and steam under pressure entering via valve 29 causes expulsion of air from the apparatus.  Valves 24, 27 are closed when the charging of fibrous material is complete and steam pressure within the vessel rises rapidly, but preferably does not exceed 300 p.s.i.  After a predetermined interval, e.g. up to five minutes, valve 27 is opened and the pressure in the vessel is rapidly reduced, say to 5-25 p.s.i.g., although a superatmospheric pressure is still maintained.  Cooking liquor is drawn into the vessel by way of reservoir 33, placed under pressure and absorbed by the fibrous material.  Following impregnation, the material can be cooked in the presence of free liquor or the latter may be evacuated and cooking conducted in the "vapour phase."  Discharge of the cooked material is effected by opening valve 26.

Title: Improvements in method and apparatus for ammoniation of phosphoric acid
IPC: C01B25/28
Filed: 1947-04-02
Abstract: Diammonium phosphate is made by continuously introducing phosphoric acid and ammonia gas into a reaction chamber, in which a constant pressure is maintained, withdrawing the ammonium phosphate and collecting in the <PICT:0640361/III/1> upper part of the chamber the mixture of steam and ammonia which is evolved, from which the ammonia is separated by condensation and, if desired, by distillation, and recycled to the chamber after addition of fresh ammonia equal to the amount used in the reaction, the respective quantities of phosphoric acid and ammonia continuously introduced into the chamber being maintained constant, and the partial pressure of ammonia gas in the chamber sufficing to prevent decomposition of the diammonium phosphate formed.  As shown, phosphoric acid from vat 2 is supplied through a measuring device 7 and siphon 12 to a saturator 6 into which hot ammonia gas is passed from pipe 20 and the hot paste which is formed is withdrawn through pipe 13, granulated and dried.  Steam formed during the reaction and ammonia pass through line 14 to a reflux condenser 15 from which cold dry ammonia is discharged into pipe 18 and returned through compressor 19 and heat exchanger 21 to the saturator after addition of fresh ammonia through valve 23; uncondensable gases are continuously purged through pipe 24, ammonia carried over being recovered in the phosphoric acid in vat 2.  The slightly ammoniacal condensate from 15 is passed to a distillation column 28 from which ammoniacal vapour is returned through pipes 32 and 14 to condenser 15 and exhausted liquor is discharged through line 32 and heat-exchanger 21.  The circulation of cooling water in condenser 15 and admission of steam to heating coil 29 of the distillation column are automatically controlled by regulators 26 and 30 respectively in conjunction with respective pyrometers 25 and 31.

Title: Improvements in or relating to moulds for metal casting
Inventor: SHAW CLIFFORD
IPC: B22C9/04
Filed: 1953-04-01
Abstract: 741,381. Moulding processes. SHAW PROCESSES, Ltd. March 18, 1954 [April 1, 1953], No. 9100/53. Class 83 (1). In an investment-moulding process, comprising the use of an investment of comminuted refractory material made into a slurry with an organic or inorganic sol other than a sol produced from an alkyl silicate, the mould (after setting, but before any substantial shrinkage due to evaporation occurs), is subjected to thermal shock by the rapid application of heat evenly and simultaneously to all the surface of the mould, the temperature being substantially in excess of that required merely to remove volatiles, whereby immediate freezing of the external dimensions is effected as well as the formation of a porous structure in the mass of the mould. The mould may be supported on a grid and introduced into an infra-red heating chamber. To promote nucleation of the cast metal at the mould face, the face may be coated with finely powdered metal before firing and while still damp, or after coating with a binder. In one example, 132 grams of comminuted sillimanite is made into a slurry with 110 c.cs. of a solution of potassium silicate and 2 per cent of magnesium sulphate. After investment and stripping the mould is placed in a muffle furnace at 500-600‹ C. In a further example for making moulds for casting high melting-point metals, a thin skin is first formed on the pattern by a slurry made by mixing 132 grams of comminuted sillimanite with 100 c.cs. of colloidal silica sol in aqueous alcohol made by hydrolysing 3437 c.cs. of ethyl silicate of silica (content 40-45 per cent), with 800 c.cs. of industrial methylated spirit and 304 c.cs. of distilled water. While gelling, the thin skin is dusted with coarse sillimanite, and then an aqueous base mix as in the first example is applied as a backing and the mould stripped and fired. The use of calcined magnesia, alumina, powdered silica, zirconia or zircon as refractories is referred to. Specification 716,394 is referred to.
