Title: Process for the treatment of fabrics containing cellulose fibres with liquid ammonia
IPC: D06M11/00
Filed: 1965-04-13
Abstract: Woven and knitted fabrics containing natural or regenerated cellulosic fibres, e.g. cotton, linen, hemp, jute and viscose rayon, are given a combination of (a) non-ironing quality, (b) shrink-resistance and (c) increased extensibility or stretch by impregnating them with liquid ammonia containing less than 10% by weight of water allowing the fibres to swell and evaporating the ammonia, while the fabric during the swelling and/or the evaporation (A) is kept under a tension or pressure which in order to obtain a fabric requiring no ironing is at least such that the fabric after the treatment is free from mussiness, (B) is kept under a tension which in order to obtain a shrink-resistant fabric is lower than the tension which causes a washing shrinkage of more than 7% and (C) is kept under a tension which, in order to get the highest possible extensibility in the warp and filling direction at the same time is as low as possible in these directions, or in order to get the highest possible extensibility in one direction is as low as possible in said direction and has a value in the other direction which is at least so high that the transverse contraction ceases upon further tension the said three tension conditions being combined during the ammonia treatment, it being possible, if necessary, to omit one or two of them depending on the construction of the untreated fabric and the properties which are desired in the finished material.  The fabric may be impregnated and swelled either by being passed continuously through a liquid ammonia bath and kept immersed in the bath during the whole time the swelling of the fibres proceeds or by applying the liquid ammonia to the extent of at least 50% by weight to the fabric either by immersion in a liquid ammonia bath with or without subsequent compression or by spraying after which the swelling is allowed to proceed in a chamber for at least 15 seconds at pressures between 0.5 and 20 atmospheres abs. giving temperatures of the fabric of between -70 and +50 DEG C., lower partial pressure of the superheated ammonia vapour giving lower temperature of the fabric for one and the same total pressure as long as liquid ammonia is present in the fabric, and the ammonia finally evaporated by means of hot air, superheated ammonia vapour, by pressing the fabric against a hot cylinder with or without felt, by means of hot or cold water or steam.

Title: Improvements in and relating to radio frequency receiving systems
IPC: H03J5/24
Filed: 1937-06-08
Abstract: 494,979. Wireless receiving circuits. STRAFFORD, F. R. W., and BELLING & LEE, Ltd. June 8, 1937, No. 15807. [Class 40 (v)] A superheterodyne receiver is adapted for operation on a shortwave band by causing the incoming frequency to beat with a harmonic of the local oscillator, the circuit of which is modified when switching over to the short-wave band in order to increase the harmonic content of the oscillator output. The local oscillator 1, derives its anode supply through a resistance 8, the back-coupling being such that when 8 is short-circuited by switch 10 on the short wave-band the valve is overdriven and the harmonic content of its output rises. In a modification, Fig. 2 (not shown), the reaction coil of the triode oscillator portion of a triode-hexode frequency changer is coupled to the anode circuit over a condenser the capacity of which is increased on the short-wave band by switching in a further condenser in parallel. The reaction coupling is thus increased and the valve generates harmonies.

Patent GB-919487-A (GB)
Title: Improvements in and relating to the purification of alcohols by distillation
IPC: C07C29/80
Filed: 1959-05-12
Abstract: Synthetic monohydric alcohols, such as C4 to C20 alcohols produced by hydrogenation of carbonyl compounds, are refined by distilling the alcohols from the crude synthetic product so that the vapours are free from high-boiling material, condensing the alcohol vapours, refluxing the condensate for 1/2 to 15 hours in the presence of 0,05 to 5% by weight of phosphoric acid and, simultaneously or subsequently, separating materials boiling below the boiling-point of the alcohols.  In Example 3, 'oxo' decanols were distilled at a pressure of 30 mm. Hg. in a fractionating column.  The distillate was refluxed for 6 hours, at a pressure of 50 mm. and a kettle-temperature of 150 DEG C., with 1% of phosphoric acid.  The alcohols were then neutralized with aqueous sodium hydroxide, and washed with water.  The alcohols were finally distilled under reduced pressure, using a fractionating column, to obtain a final product, which was found to be suitable for use in the preparation of colourless esters (see Group IV(b).  In Example 9, crude 2-ethylhexanol, produced by hydrogenation of the dehydration product from the aldol-condensation of butyraldehyde, was freed from high-boiling impurities by fractionation under a pressure of 50 mm. The alcohol was then fractionated in a system comprising two columns connected in series by an adaptor for taking-off a side-stream, the upper column being provided with an automatic reflux-head connected to a vacuum system.  A portion of the alcohol was added to the kettle together with a small proportion of phosphoric acid. Heat was applied to the kettle and the pressure adjusted at 200 mm. to set up refluxing at a kettle-temperature of 150 DEG C.  The remainder of the alcohol was added continuously, and withdrawal of side-stream and overhead distillate was commenced.  The rate of feed and withdrawal streams was adjusted so that the residence-time of the alcohol in the kettle was 6 hours.  The refined alcohol, obtained as side-stream, satisfied the colour-test.ALSO:Colourless esters, for use as plasticizers, are produced by reacting aliphatic or aromatic acids with synthetic monohydric alcohols, such as C4 to C20 alcohols obtained by hydrogenation of carbonyl compounds, the alcohols being refined, prior to esterification, by a distillation process including refluxing the alcohols with a small proportion of phosphoric acid (see Group III).  In Example 10, didecyl adipate is produced by reacting adipic acid with refined "oxo" decanols, using sulphuric acid as catalyst.  After heating to 180 DEG C., the pressure is reduced to obtain good reflux, and water of reaction is removed as a separate phase.  After the reaction the excess alcohols are removed by distillation under reduced pressure, steam being sparged through the mixture in the last stage of the distillation.
