Title: Gas converters
IPC: F01N13/14
Filed: 1971-06-02
Abstract: 1393247 Treating exhaust gas FOSECO INTERNATIONAL Ltd 18 May 1972 [2 June 1971] 18638/71 Heading F1B [Also in Division F4] A gas converter for treating the exhaust gases of an internal-combustion engine has a reaction chamber lined with a layer of refractory heat insulating material which is formed of a dry composition containing inorganic refactory fibre and a water soluble inorganic binding agent serving to bond the composition firmly throughout. The surface which contacts the hot gases in use may be strengthened after drying by re-impregnating the material of the layer with an aqueous solution of the binder and drying it again using a drying method which causes migration of the binder to the surface e.g. hot air oven drying. The inorganic fibres may be aluminosilicate, calcium silicate, asbestos, alumina, silica, zirconia or carbon fibres. More than one of these may be used in combination. The binding agent may be colloidal silica sol, colloidal alumina sol, sidium silicate, potassium silicate, ethyl silicate, or a metallic phosphate, or borate. The composition may also include up to 10% of finely divided  refractory material e.g. alumina, silica, calcined rice husks, diatomite, kieselguhr, magnesia, silicon carbide, silicon nitride or fireclay. Where a mixture of colloidal silica sol and aluminosilicate fibre is used the dried composition should have silica of 55-90 wt per cent. If it is too low, more silica can be added by dipping in further silica sol and drying, either as before by hot air or by micro-wave drying which does not cause the silica sol to migrate. The lining of the chamber may be in two layers having different densities. The lower density layer may be honeycombed. The surface in contact with the gas stream may be faced with a refractory dressing e.g. an aqueous suspension of alumina, zirconia, zirconium silicate, magnesia, silica or the like, or a flame-spray refractory coating. The outer casing may be of mild steel and the lining may be rivetted to it or stuck using a metal power and aqueous alkali metal silicate as described in Specification 1393246. Alternatively the composition may be applied as a paste to the inner wall of the outer casing and later dried.

Abstract: 655,958. Woven fabrics; threads. RADIO PATENTS CORPORATION. Nov. 27, 1945, Nos. 18709/48 and 18710/48. Convention dates, March 31, 1939 and March 16, 1940. [Classes 120(iii) and 142(iv)] [Also in Group VIII] An open mesh screen material composed of monofils of thermoplastic material is made by weaving the monofils into a screen, heating the latter to a temperature sufficient to cause the monofils to flow and crimp about intersecting monofils without fusing together, and permitting them to acquire a permanent resilient set in complementarily crimped condition. The warp monofils 22, Fig. 1, which may be, for example, of nylon. may be crimped before weaving by passage between rollers 20 having complementary angular recesses 23 and projections 23a, those for treating adjacent strands being staggered. Alternatively, the strands may be led between intermeshing rollers 210, 211, Fig. 10, having continuous corrugations, the crimps in alternate strands being brought into staggered relation with those on the remainder by passing them round a roller 213 giving a difference in path. The crimping rollers may be heated, or pressure alone may be used. Specifications 513,354, [Group VIII], and 655,932 are referred to.

Abstract: 315,831. Hansen, H. C. July 19, 1928, [Convention date]. Testing coins. - Coin detecting mechanism which can distinguish between coins with or without a flange, has a pair of spring actuated feelers 9 pivoted at 10, between which the coins pass. A coin, after falling through the coin passage 2 rests on the pivoted pawl 7 between tbe beaks 12 of the feelers 9. The downward movement of the coin is thus stopped but it moves to the left guided by the beaks. When its centre of gravity is sufficiently to the left of the gap between the beaks 12 it is no longer supported by the pawl 7 and falls vertically to the right of the partition 13. The pawl 7, then returns by gravity to its normal position as shown in Fig. 1. If the coin has no flange it will not be acted upon by the beaks and will fall to the left of the partition 13 to be rejected.

Title: Process for the manufacture of a stable, water soluble sulphuric acid ester from 4:6-dichloro-6-methoxy-bis-thionaphtheneindigo
IPC: C09B9/04
Filed: 1930-06-25
Abstract: Sulphuric ester salts of leuco-4 : 6-dichlor-61-methoxythioindigo are made by treating the leuco compound of the dyestuff with sulphur trioxide or an agent yielding sulphur trioxide in the presence of a tertiary base, and converting the acid sulphuric ester thus obtained into stable salts.  In an example, the leuco compound is treated with chlorsulphonic acid in a mixture of dimethylaniline and chlorbenzene; the product, obtained by salting out in the form of the sodium salt, gives deep scarlet red shades when dyed or printed on vegetable or animal fibres and developed with oxidizing agents.  The parent dyestuff is made by condensing a 2-anil of 2 : 3-diketodihydro-6-methoxythionaphthene with 4 : 6-dichlor-3-oxythionaphene (made by treating 3 : 5-dichlorphenylglycollic chloride with aluminium chloride) or by condensing a 2-anil of 4 : 6-dichlor-3-oxythionaphene with 6-methoxy-3-oxythionaphene.

Abstract: 384,350. Gramophones. LARISCH, H., 22, Zahngasse, Dresden, Germany. July 6, 1931, No. 19425. [Class 40 (ii).] An automatic stopping device for gramophones comprises a casing 11 adapted to be swung by the tone-arm about a vertical shaft 17 whereby a gear wheel system 12; 13, 14 in the casing is caused during playing of a record to turn about a spur-wheel 16 on the shaft 17, whilst when the tone-arm receives an accelerated movement due to the terminating groove on the record the gear wheel system cannot immediately run at this increased speed and forms a rigid connection with the shaft 17 so as to effect application of the brake. The gear wheel system includes a nywheel 15. The shaft 17 is provided with a depending sleeve 18 adapted to engage frictionally with a shaft 10 mounted upon a casing 2 and carrying a pawl 8 which normally holds a spring-loaded brake bolt 4 in retracted position. When the shaft 17 is oscillated at the end of playing a record, the pawl 8 is withdrawn and the bolt 4 moves forwardly so that a braking device in the form of a curved leather-covered arm 9 engages the turntable. A lever 20 is adjustably mounted on the casing 11 for engaging the tone-arm. During traverse of the casing by the tone-arm, a spring 21 is wound so that at the end of playing a record the spring effects return movement of the casing.

Title: Apparatus for solving vector triangles

Abstract: 458,274. Electric signalling systems ; calculating - apparatus. BREWERTON, A. E., 39, Higher Drive, Purley, Surrey. July 8, 1935, No. 19428. [Class 40 (i)] [See also Group XIX] In apparatus for obtaining the solution of vector problems, the vectors are represented by electric currents or voltages whose magnitudes are proportional to those of the vectors, and the effects produced by the currents are combined to produce a direct indication of the value of the resultant vector. The direction of the resultant vector is also indicated directly. As shown in the Figure, the apparatus effects the determination of true wind in terms of apparent wind and the velocity of a ship or other moving body. Two potentiometers 5a, 6a supplied from a generator 7, driven by an anemometer, are provided in order to resolve a vector, e.g. the relative velocity of the wind to the ship, into two components at right angles. A wheel 2 which is set in the apparent wind direction operates, through the slides 5, 6, the movable contacts of the potentiometer in order that sine and cosine components of the output of the generator 7 may be derived over the leads 5b, 6b. A potentiometer 8 having a movable contact operated manually or automatically from the ship's log is connected in series with the output of the potentiometer 6a and the two outputs are applied to the two heating elements 10, 11 of the thermo-couples 10a, 11a which operate an instrument 12 to give an indication of the magnitude of the resultant quantity. True wind direction is given by an instrument 13 having stator coils 13a, 13b supplied from the two outputs. Instead of using an instrument operated by thermocouples, an instrument operated by the combined thermal expansions of heated wires may be employed. The system may be operated by hand, instead of automatically in order to perform calculations.
