Title: Improvements relating to the pyrolysis of bituminous shale in a fluidized bed
IPC: C10G1/02
Filed: 1960-04-04
Abstract: 891,200. Distilling oil shale. SVENSKA SKIFFEROLJE A.B. April 4, 1960 (April 13, 1959], No. 11804/60. Class 55 (1). Oil shale ground to a size <1.5 mm. and preferably < 1.0 mm. is distilled in a fluidized bed at between 550 ‹ and 575 C. for a period of time > 10 minutes, e.g. 15-75 minutes, preferably about 45 minutes. The gas and vapour released may be sufficient to fluidize the material being distilled but an additional fluidizing gas, e.g. steam, may be supplied which may be in an amount equal to the volume of gas and vapour released from the shale. Heat may be supplied by combusting the shale coke produced and adding the hot coke or ashes to the distillation zone or by passing molten metal or superheated steam through coils arranged in the distillation zone.

Title: Process for the manufacture of a stable complex fertiliser
IPC: C05B11/06
Filed: 1952-05-09
Abstract: A fertilizer containing dicalcium phosphate and ammonium nitrate is obtained by attacking natural phosphate with nitric acid and treating the resultant mass with ammonia to bring the pH of the liquid to 3, then with ammonia and sulphuric acid simultaneously to increase the pH up to 5, and finally with ammonia alone until the mass contains no more phosphoric acid soluble in water.  The temperature is maintained between 90 and 100 DEG C during the additions.  The paste obtained, if desired with added potassium salts, may be dried and granulated. According to an example, 4180 kilos of Moroccan phosphate (34 per cent P2O5) is treated with 7,500 kilos of 52 per cent nitric acid and the product is passed successively through seven tanks with stirrers. Gaseous ammonia is introduced into the first and last tanks and mixture of gaseous ammonia and sulphuric acid introduced into tanks 2 to 6.  The product contains 8.25 per cent each of nitrate and ammoniacal nitrogen and 14 per cent of phosphoric acid of which none is water soluble.ALSO:A fertilizer containing dicalcium phosphate and ammonium nitrate is obtained by attacking natural phosphate with nitric acid and treating the resultant mass with ammonia to bring the pH of the liquid to 3, then with ammonia and sulphuric acid simultaneously to increase the pH up to 5 and finally with ammonia alone until the mass contains no more phosphoric acid soluble in water.

Title: Improvements in or relating to moulds for casting of metals or metal alloys
IPC: B22C1/20
Filed: 1943-07-26
Abstract: In making moulds or cores for casting magnesium or other metal, sand &c. is mixed to the usual consistency, moulding with a binder liquid consisting of a hardenable organic silicon compound, e.g. hydrolysed silicon ester with between one and four molecular proportions of water, as described in Specification 575,752, and a gelling accelerator.  This may consist of hydrochloric acid, lime, or magnesia, but preferably an accelerator, such as piperidine, is used which also condenses the binder to form a polymerized resinous body. The accelerator and water may be mixed with the binder or with the material bound.  The mixture may be used for making cores, one-piece moulds, about an easily fusible pattern, or two-part moulds, by tamping and vibrating or by high pressure, e.g. 200-1000 lbs. per square inch, or for lining a metal mould or one made from sand, slip or other cheap materials. Reinforcing material, such as wire, woven cloth, or asbestos p  cloth wetted with a slurry of fine aggregate and bonding liquid, may be inserted in the mass while filling a mould box.  The pattern and, if desired, the sides of the box are removed when gelling has taken place, say within half an hour, and the mould is then dried at room temperature for, say, eight hours and heated to 700-1000 DEG  C. in an hour or more.  Semi-permanent moulds may be made thus, using refractory powders bonded as described.  For low temperature castings the refractory is replaced by plaster of Paris, magnesium oxychloride or cement fondu, the mould preferably lined with fine aggregate also bonded as described.

Patent GB-125121-A (GB)
IPC: F41G5/08
Abstract: 125,121. Barr & Stroud, Barr, A., and Stroud, W. May 29, 1916. Calculating-apparatus.-Relates to sighting-apparatus for anti-aircraft guns, of the kind embodying corrections either of fuse-timing or of tangent angle of elevation, for height or range of target, angle nf sight and velocity towards or away from gun. The invention comprises an arrangement embodying two surface cams designed to impart or indicate corrected angles of tangent elevation for an approaching or receding target respectively at selected maximum speed. The cams actuate vertical plungers, the movements of which may be compounded in any desired ratio to indicate the correction for speeds under the maximum. In the arrangement shown, the vertical plungers P<1>, P<2> rest upon surface cams 2, 3 which are designed respectively for an approaching or receding target travelling at the rate of 100 miles per hour. The cams are rotated according to the angle of sight, and the plungers are adjusted longitudinally in relation to the cams according to height (or range) of the target. Longitudinal adjustment of the plungers is affected by means of an handle 12, operating a screwed spindle 7 carrying a non- rotatable nut 6 in which the plungers are mounted. The adjustment is controlled by means of a height (or range) indicator 13, 14, The movements of the plungers P', P<2> are transmitted through the medium of a link 19 to a third plunger 20 operating the indicator 22, 23 by means of rack teeth thereon engaging an elongated pinion 21. The plunger 20 is adjusted longitudinally in relation to the link 19 by rotation of a handle 15 which operates a splined shaft 10, carrying a screwed sleeve 11 rotatable within a nut member 18 which carries the plunger 20. The sleeve 11 is connected by arms 8, 9 to the nut member 6 so as to move therewith. By means of the link 19 the adjustments of the plungers P', P<2> may be compounded, before being transmitted to the plunger 20. When situated immediately over either of the plungers P<1>, P<2>, the plunger 20 is adjusted for maximum speed of target, the mid position corresponds to a stationary target, and intermediate positions to various speeds of target less than the maximum selected speed. The speed adjustment effected by means of the handle 15 is indicated by a dial and pointer 16, 17. The indicator 22, 23 may show tangent elevation angles, or fuse times, or two indicators may be simultaneously operated. The device may be associated with the gun by which the angle of sight adjustment may be effected automatically. The cam surfaces may be designed according to tangent elevation instead of angles of sight. The indicator 22, 23 may be arranged in direct conjunction with the tangent elevation gear of the gun, so that the tangent elevation may be indicated by the coincidence of the two pointers. Reference has been directed by the Comptroller to Specification 16013/15, [Class 92 (ii), Ordnance &c.].

[Class 143.] In apparatus for weighing and filling basic slag, cyanide of calcium, cement, lime, gypsum, &c., into sacks, the points of the filling and weighing mechanism at which dust is generated are enclosed in a casing connected to an air exhauster. A blade wheel 2 charges the material from a hopper 1 through an outlet 3 into a nozzle 4 on which the sack is held. The nozzle is connected to the scale beam and is adapted to move downwardly when the predetermined weight has been reached. A closing valve, comprising an oscillable segment 6 with an aperture 7 is adapted to be moved to close the outlet 3 at the same time. The actuation of the segment 6 may be effected by a weighted arm, locked by a pawl in the open position until the descent of the filled bag is caused to close the circuit of an electromagnet, and to withdraw the pawl. The segment may be replaced by a rotary disc valve with several openings, and the aperture or apertures may be oval and with their greater diameters disposed radially in respect of the spindle 8. The air casing 16 surrounds the joints at both sides of the valve 6, and also the casing 9 in which the spindle 8 is mounted. A felt joint 18 assists to protect the ball bearings 17 and prevents the drawing in of too much air from the outside. The casing is extended as a hood 19 to cover the nozzle 4, being provided with an air slot 20, which widens towards the end, for collecting dust escaping from the upper end of the sack.
