Filed: 1917-07-25
Abstract: 109,254. Espenhahn, E. V. Aug. 8, 1916, [Convention date]. Sodium ferrocyanide; sodium ferrous ferrocyanide; hydrocyanic acid; ammonium sulphate.- Gases containing cyanogen compounds, with or without ammonia, after removing the tar, are treated at a comparatively high temperature (about the dew-point), with a concentrated solution of alkali, such as sodium carbonate, containing in suspension ferrous sulphide or sodium ferrous ferrocyanide. The washing-liquor, after separating insoluble matter, is cooled to crystallize sodium ferrocyanide, and the gases leaving the washer may be passed into sulphuric acid or into a solution of ferrous sulphate, or part may be treated in each of these ways, ammonium sulphate being obtained and, if desired, ferrous sulphide for use in the principal process. The sodium ferrocyanide may be treated with sulphuric acid to obtain sodium ferrous ferrocyanide for use as described above, and hydrocyanic acid tor conversion into cyanide.

Patent GB-740269-A (GB)
Title: Organic polymeric compounds and materials containing phosphorous and nitrogen
IPC: C08G79/02
Filed: 1953-04-20
Abstract: Condensation polymers in liquid, resin or gell form or polymeric material, are made by reacting tetra-(hydroxymethyl) phosphonium chloride (THPC) or tri-(hydroxymethyl) phosphine oxide (THPO) with (a) urea, melamine, guanidine or any mixture thereof, either alone or in the presence of formaldehyde, or (b) a fibrous cellulose derivative containing primary amino groups, in the presence or absence of urea, melamine, guanidine or any mixture thereof with or without formaldehyde.  The formaldehyde may be added in the form of a water-soluble condensate with melamine, guanidine or urea.  The condensation of THPC may be effected in aqueous media and in the presence of acidic or basic catalysts, e.g. acetic and hydrochloric acids and alkali metal carbonates and bicarbonates, and preferably by reacting 1 part (by weight) of THPC with (a) 1/6 to 1/2 part of melamine &c., or (b) 1/6 to 2/3 part of a water-soluble condensate of melamine &c. with formaldehyde, and 1 to 3 parts of water at 50 DEG to 100 DEG  C.  Liquid polymers can be isolated by adding to the reaction medium a solvent for water, e.g. methyl or ethyl alcohol. The polymers may be used in making moulded articles, e.g. buttons, food containers and electrical insulators, and synthetic coatings and adhesives.  Examples 1 to 6 describe the preparation of the condensation polymers.  Organic fibrous materials, e.g. cotton fibres, slivers, yarns, threads, textiles, ropes, paper and cardboard, may be flame-proofed by impregnation with an aqueous solution of the partially condensed polymers and heat curing.  Where cotton fibres are used, HCl formed during the condensation is preferably neutralized by adding an alkali metal carbonate or bicarbonate, guanidine carbonate or urea to the reaction medium before, during or after the condensation.  The reaction of aminized cellulose, such as spun aminoethylated cotton cellulose fibres or cellulose treated with aqueous caustic soda containing 2-aminoethyl sulphuric acid (see U.S.A. Specification 2,459,222), with the partial condensation polymers is preferably effected by impregnating the aminized fibres with an aqueous solution of the polymer, removing excess liquid and curing at 80 DEG  to 160 DEG  C.  Examples 7-10 describe the flame-proofing of cotton print and examples 11-13 describe the treatment of aminized cellulose.

Title: Chemical heating composition
IPC: C09K5/18
Filed: 1936-04-15
Abstract: 475,411. Heating by chemical action. TATE, F. R. (Kendall Co.) April 15, 1936, No. 10861. [Class 64 (ii)] A composition for producing heat by chemical action comprises a stable metal above iron in the electromotive series, and a substance capable of supplying a metallic ion upon addition of a liquid ionizing medium, the metallic ion being electrolytically replaceable by the said metal. Aluminium, magnesium, manganese and zinc, are suitable metals, and the ionizing medium may be cupric chloride to which water is added, or preferably lead chloride, lead sulphate, antimony oxychloride, cuprous chloride or mercurous chloride. Substances insoluble in water may alternatively be used, such as cupric carbonate, phosphate or oxide, cuprous oxide, copper, tin, nickel, antimony, or antimony oxide. The insolubility of these substances in water necessitates the addition of another substance which, with water, effects their solution. An example of such a composition consists of: aluminium 15 grams, cupric carbonate 15 grams, barium chloride 1 gram, aluminium sulphate 2 grams. Barium chloride may be replaced by the chloride, sulphate or nitrate of ammonium or the alkali or alkaline earth metals. Aluminium sulphate may be replaced by sulphates and other acid-forming compounds of magnesium, manganese and zinc. The combination of barium chloride and aluminium sulphate may be replaced by any substances which are stable when dry, and which produce an acid solution on addition of water. Acids such as oxalic, tartaric, boric or silicic may be used. The proportion of cupric carbonate or other replaceable electrolyte may be reduced by including in the composition some water - soluble electrolyte such as sodium chloride. The aluminium or other metal is used in proportion greater than the chemical equivalent and not more than 140 molecules of metal to 1 molecule of the cupric carbonate or the like.

Title: High voltage power supplies
IPC: H02M7/10
Filed: 1973-03-07
Abstract: 1408822 Voltage multiplying rectifiers RADIATION DYNAMICS Inc 7 March 1973 [15  March 1972] 11200/73 Heading H2F [Also in Division H1] A capacitor structure for power supply comprises a plurality of conductive cylinders 13, 14, 16, 17 and associated with each cylinder a group of sleeves such as 18, 19, 20 coaxial with the cylinder and axially spaced along it, the spacing being such as to prevent voltage breakdown between adjacent sleeves. As shown, in a power supply for use with high voltage accelerators (see Division H3) the cylinders which may be hollow, are disposed symmetrically within vessel 1, 2, 3, which also contains step-up transformer 4 and, in the central space, circuit board 21 supporting solid state rectifiers. Diametrically opposite cylinders are electrically connected in pairs to provide a series parallel assembly (Fig. 4), the pairs being connected to opposite ends of the transformer secondary winding. The rectifiers, which are located remote from the spaces between sleeves, join sleeves having opposite polarity of the alternating voltage applied thereto, and since they are solid state there is room for several rectifier junctions in each rectifier stage to overcome the peak inverse voltage limitations of each rectifier stage. In a modification (Fig. 5, also Fig. 6, not shown) the interconnection is such as to provide a half-wave voltage doubler, all capacitors and associated rectifiers being connected in series and individual capacitors being charged through a different rectifier stage. In further modifications, a single phase, full wave voltage doubler, constituted by two half-wave circuits in parallel, is provided (Fig. 7, not shown), or a three-phase half-wave voltage doubler (Figs. 8, 9, not shown) or a three-phase full-wave voltage doubler (Fig. 10, not shown). The latter two embodiments differ from the Fig. 1 arrangement in using those inner cylinders and associated groups of sleeves, and arrangements using two inner cylinders are envisaged. The vessel may be filled with insulating gas, e.g. sulphur hexafluoride under pressure, or, less desirably a solid dielectric may separate the capacitor plates.

Title: Improvements in or relating to compressed air brakes for railway vehicles
IPC: B60T15/48
Filed: 1956-04-13
Abstract: 789,114. Fluid-pressure brakes. KNORRBREMSE GES. April 13, 1956 [April 14, 1955], No. 11357/56. Class 103 (1). A compressed-air brake system comprises first and second air storage reservoirs 1 and 2 arranged to be charged off the brake pipe 3 through a control valve 4, a timing delay valve 6 being inserted in the pipe between the reservoirs so as to shut off such communication after a certain time interval, the further charging of reservoir 2 then taking place by way of a restriction or nozzle 7. This arrangement is intended to avoid the condition in a relatively long train wherein release of the brakes takes place sluggishly owing to the fact that the pressure in the main air pipe at the end of the train increases very slowly owing to the absorption capacity of the storage reservoir. In one of a number of further embodiments, Fig. 4, the reservoir 2 may be changed unrestrictedly from the brake pipe 3 so long as brake cylinder pressure maintains valve 9 open, shutting of the valve requiring further charge of reservoir 2 from reservoir 1 by way of restriction nozzle 7.

Abstract: 739,981. Automatic control systems. GENERAL ELECTRIC CO. April 20, 1954 [April 20, 1953], No. 11368/54. Class 38 (4). The anode-cathode current of a thermionic discharge device such as an X-ray tube 11 is stabilized by applying the potential across an impedance 18, in the anode-cathode circuit, to a valve 19, while a valve 20 is fed with a reference potential from potentiometer 22, there being a diode 24 connecting the inputs to the valves 19, 20, and the potential developed in the load circuit 25, 26 being applied to a variable impedance, e.g. a saturable reactor 28, to vary the heating current to the filament of the device 11. The X-ray tube 11 is fed with A.C., so that pulses are supplied to valve 19; the diode 24 maintains the grid of valve 19 at least at the same potential as the grid of valve 20, but allows the grid of valve 19 to rise to a higher potential when the tube 11 passes a higher current, thus developing an output current in the reactor winding 27.
