Title: Improvements in and relating to the treatment of acid waste waters and the like
IPC: C02F1/66
Filed: 1952-12-22
Abstract: Acid waste waters and the like are neutralized by ignited magnesite. The magnesite is preferably ignited nearly to the sintering point and has a grain size not materially less than one millimetre, preferably 5 to 12 mms.  The residual carbon dioxide content is preferably some 12 per cent of that before ignition. The ignited magnesite may have a magnesia content of some 60 to p  95 per cent, preferably from 70 to 90 per cent.  In order to reduce heat generation on hydration or to retard hydration of the ignited material, a magnesite containing impurities of a colloidal nature is preferred, having, for example, between 2 and 6 per cent of silica but not less than one per cent. The ignited magnesite should be washed with water for one or two days before actual use but such washing may take place in situ by increasing the flow. The vessel in which the reaction is carried out may be made from a polyvinyl chloride plastic.

Title: Improvements in the reversal development of light-sensitive silver halide emulsions
IPC: G03C5/50
Filed: 1936-11-30
Abstract: 489,845. Photographic reversal processes ; colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Nov. 30, 1936, No. 32745. [Class 98 (ii)] In a photographic reversal process without intermediate exposure, the emulsion layer is treated before the second development in an acid bath containing an odourless sulphur compound which produces developable silver nuclei. Acids specified are acetic, oxalic, citric, sulphuric, and phosphoric acids, and odourless sulphur compounds specified are thiourea, N-allylthiourea, N, N-diethyl-N-allylthiourea, N-phenylthiourea and N, N-diethanol- N-phenylthiourea. The process may be applied to the reversal development of silver halide emulsion layers containing dyestuff components which are fast to diffusion such as are described in Specifications 458,400, 465,823, 479,838, 483,000, 484,698, 489,093, and 489,274. In an example, multilayer material in which the emulsion layers contain dyestuff components fast to diffusion is developed in amidol or metol, treated in a bath containing acetic acid and thiosinamine, developed in a colour developer such as N, N-diethyl-p-phenylene diamine, washed, the silver image removed with Farmer's reducer, and washed.

Title: Improvements relating to effecting combustion and ignition in internal combustion engines
IPC: F02B1/00
Filed: 1932-11-19
Abstract: 410,752. Igniting in oil engines. KENNEDY, H. E., 105, Tunnel Road, Berkeley, California, U.S.A. Nov. 19, 1932, No. 32782. [Classes 7 (iii) and 7 (iv).] Ignition in an oil engine. is effected by causing high-tension sparks to pass continuously across the terminals of a spark plug 14 during the whole of the fuel injection period. The plug 16 is mounted in proximity to the fuel injector 12 ; the air is compressed before the fuel injection. The sparking starts just before injection commences. Igniting systems.-An alternator 15 supplies the current through a transformer and distributer 17, an interrupter 16 controlling the time during which sparking takes place. To ensure efficient working at starting of the engine an extra coil is mounted on the alternator field winding, this coil being in circuit with the starter motor 18.

Title: Process of manufacturing a citrate soluble phosphatic compound, useful as a fertilizer or an ingredient thereof
IPC: C05B11/06
Filed: 1946-11-05
Abstract: Citrate soluble phosphatic compounds are made from acid solutions containing calcium and phosphate or hydrophosphate ions by simultaneously introducing the acid solution, ammonia and sulphur dioxide or a sulphite or bisulphite into a reaction vessel, maintaining the liquid reaction mixture at a pH value 6-8 by continuously regulating the flow of the acid solution and ammonia, and withdrawing a precipitate of the citrate soluble phosphatic compound, if desired mixed with the mother liquor, from the reaction vessel.  The precipitate may be separated from the solution and dried or the whole may be evaporated to a concentrated mixed fertilizer. The process may be started by introducing the acid solution, ammonia and sulphur dioxide, sulphite or bisulphite into a quantity of an already substantial neutral liquid, e.g. the reaction mixture resulting from a preceding run.  The acid phosphate solution may be obtained by dissolving a phosphate in nitric acid.  The proportion of sulphite and ammonia may be adjusted to give a pH value of 6 to 8.ALSO:Citrate soluble phosphatic compounds suitable as fertilizers or ingredients thereof are made from acid solutions containing calcium and phosphate or hydrophosphate ions by simultaneously introducing the acid phosphate solution, ammonia and sulphur dioxide or a sulphite or bisulphite into a reaction vessel, maintaining the liquid reaction mixture at a pH value 6-8 by continuously regulating the flow of the acid solution and ammonia and withdrawing a precipitate of the citrate soluble phosphatic compound, if desired mixed with the mother liquor, from the reaction vessel.

Abstract: 173,944. Adlam, E. G. Nov. 22, 1920. Filling with liquids; stands.-The rocking cock D of a cask-filling apparatus is mounted on a, ball- and-socket joint permitting a movement of the cock transverse to the axis of the cask, which is supported on four ball-bearing castors V, each comprising a large ball V<1>, Fig. 8, carried by a ring V<2> of smaller balls. The apparatus comprises a liquid container A arranged to contain a constant quantity of liquid and connected by liquid and air pipes C, F, respectively, to the racking cock, which is of the type having an annular air chamber a<2>, Fig. 2, surrounding the liquid passage a'. The joint is constituted by a ball on the supporting rod G entering a socket formed on the sliding block h, a pivot pin u being provided. The block h slides on a guide rod J and is connected to a counterbalance weight situated inside the hollow standard A<1>. In operation, the cock is lowered until a pad l, Fig. 2, becomes seated in the filling opening of the cask. The block h is then locked to the rod J by turning forward a lever (not shown) connected to the spindle 0, which operates cam mechanism to effect this; a further forward movement is then given to the lever and causes a cam to press on the upper end of the rod G, so ensuring close contact between the pad l and the filling opening of the cask.

Abstract: 1,237,468. Prestressed concrete bridges. COMPAGNIE INDUSTRIELLE DE TRAVAUX. 30 June, 1969 [17 July, 1968], No. 32965/69. Heading E1G. In a method of constructing and advancing a bridging structure of precast prestressed concrete sections 6, 7..12 resting on piers 1, 2, 3, 4, &c., the sections are successively cast in box form and provisionally prestressed and are successively connected to one another and provisionally prestressed together, the structure being progressively advanced from an abutment pier 1 by sliding on the piers after the addition of each new section, and the provisional prestressing being replaced by final parabolic prestressing when the structure is in its final position. The structure is advanced by means of one or more hydraulic jacks 18 positioned horizontally on either side and supported on the abutment pier 1, the jack rods being connected by screw-threaded or smooth tie-rods 20 to brackets 19 secured to a boxsection. Sliding over the piers is achieved by means of sliding supports having concrete upper plates 33 in contact with the structure, elastomeric intermediate plates 34 and cellular polytetrafluoroethylene lower plates 35, which sliding supports slide with the structure on stainless steel plates 30 secured to the tops of the piers. The structure is advanced by the jacks 18 in increments of about 1 metre, and vertical jacks 31 on the piers then lift the struture to free the sliding supports which are returned to their original positions for the next incremental sliding advance. Temporary lateral jacks may be positioned at the tops of the piers to guide the structure, and temporary guying 37 reduces the sag of the overhanging structure.
