Patent GB-190961-A (GB)
Title: Improvements in method of recovering hydrocyanic acid from gases
IPC: C10K1/10
Filed: 1922-04-10
Abstract: Hydrocyanic acid is removed from gases containing ammonia, carbon dioxide and sulphuretted hydrogen, by scrubbing with a copper compound such as cuprous sulphide, cupric sulphate, or cupric oxide in water, the absorption being carried on until the solution contains at least two atoms of copper (as a cuprocyanide, (NH4)2Cu (CN)3 for each molecule of sulphuretted hydrogen in solution.  When starting with cuprous sulphide therefore, no sulphuretted hydrogen is on balance absorbed.  Alternatively less absorption may be effected and the solution boiled to remove sulphuretted hydrogen in excess, with the loss however of some hydrocyanic acid.  In any case, boiling is advantageous to remove carbon dioxide; and to avoid loss of hydrocyanic acid in this step it is preferred to add cuprous cyanide before the boiling, which causes the precipitation of cuprous sulphide (returned to the absorption step) and the formation of another cuprocyanide probably NH4Cu (CN)2.  The solution is then distilled with dilute sulphuric acid to obtain hydrocyanic acid and insoluble cuprous cyanide (and cuprous sulphide if the step of heating with cuprous cyanide has not been employed).  The insoluble matter may be returned to the absorption step.

Title: Improvements relating to the ornamentation of textile materials
IPC: D06P5/00
Filed: 1943-06-24
Abstract: In the fixation on textile materials of basic dyestuffs by means of lake-forming inorganic acids, the basic dyestuff and a water-soluble salt of the acid component are applied together in aqueous alkaline solution and thereafter the insoluble lake is precipitated by acidification.  Advantageously, the dyestuff is dissolved in water containing a water-miscible non-acidic solvent and an alkaline aqueous solution of a salt of the lake-forming component is mixed therewith, preferably after adjustment of the pH to 9-11, and the mixture, with or without suitable thickening, is applied to the textile material which is then dried, if desired steamed, and acidified to precipitate the lake.  The lake-forming acid is preferably one derived from a metallic transitional element, e.g. molybdic acid or tungstic acid, or is a heteropoly acid in which the nuclear acid is phosphoric, arsenic, or silicic acid and the co-ordinated acid is derived from a metallic transitional element as above.  In examples: (1) an aqueous solution containing Victoria Blue R, alcohol and urea, is mixed with Carob bean thickening and an alkaline solution of sodium molybdate adjusted to a pH of 9-11, and the mixture is printed on a viscose rayon cr<\>zepe fabric, which is then dried, steamed for one hour to assist penetration, further treated with steam containing acetic acid vapour, soaped, rinsed and dried; (2) an aqueous solution of Xylene Blue AS containing ethylene glycol monoethyl ether, glycerol, disodium hydrogen phosphate and sodium dihydrogen phosphate is mixed with tragacanth thickening and an aqueous solution of sodium phospho-molybdate at a pH of 9-11 and the mixture is printed on a spun viscose fabric which is then further treated as in (1), the steaming being for 20 minutes; (3) an aqueous solution of Rhodanine 6G extra containing ethylene glycol and disodium hydrogen phosphate is mixed with an aqueous solution of sodium molybdate at a pH of 9-11, the mixture is padded on to viscose taffeta material which is then treated with steam containing acetic acid vapour, washed and dried; (4) an aqueous solution of Brilliant Green crystals YS containing diethylene glycol monoethyl ether is mixed with tragacanth thickening and an aqueous solution of sodium phospho-tungstate at a pH of 9-11 and the resulting paste is printed on a cotton fabric which is then further treated as in (3); (5) an aqueous solution of Methyl Violet containing diethylene glycol and tragacanth thickening is mixed with an aqueous solution of sodium tungstate at a pH of 9-11 and the resulting paste is printed on a fabric of cotton warp and viscose filament weft which is then steamed for 3 minutes, passed through steam containing acetic acid vapour, washed and dried.

Title: Improvements in or relating to sheet feeding mechanism for sheet folding machines
IPC: B65H5/24
Filed: 1934-04-06
Abstract: 437,809. Feeding sheets; folding paper. DIXON, H. E., 26, Holborn Viaduct, London,- (Brehmer. Geb.; Plagwitz, Leipsic, Germany) April 6, 1934, Nos. 10446 and 10447. [Class 100 (i)] Sheets are fed to a folder F of the buckling type in an overlapping stream, the extent of overlap of the successive sheets being so controlled that as a folded sheet S<1>, Fig. 11, is moving out of a folding pocket 1, the succeeding sheet S<2> has already entered the pocket 1, so that the folded sheets leave the rollers B<2>, B<3> without intervals, and thus the rate of producing folded sheets is increased. The sheets are fed from the top of a fanned out pile a, Fig. 1, or from the bottom of a series of overlapping sheets all, Fig. 6, which are formed from a pile a. by the aid of a belt 6, a roller 4, a pressing roller 7, a roller 10 driven at a greater speed than the belt 6, and a guide 11 and pressing roller 12. The final overlapping stream in which the sheets overlap each other to the extent of about half the length of a sheet is produced by the co-operation of feed rollers d, d<1>, Fig. 1, or 17, 18, Fig. 6, with a suction feeder B which is adjustable in position and is set at a distance from the feed rollers equal to the required amount of overlap. The suction feeder is formed of a suction chamber c, Fig. 1, or 16, Fig. 6, and a co-operating apertured belt passing over feed rollers b<1>, b<2>, b<3>. To prevent the feeding of underlying sheets prematurely a braking device k, Fig. 1, or a suction roller 19, Fig. 6, holds back the underlying sheets. The device k is formed as a gravity shoe or claw with separate hooks loosely mounted in arrow formation and so adjusted that when a sheet reaches the rollers d only the foremost hooks are in contact with the rear of this sheet. A curved guide n, Fig. 1, directs the foremost sheet to the rollers d, d<1>, and a feeler m releases a latch for controlling the advancement of the pile a by ratchet mechanism. The pile advance in the modification, Fig. 6, is controlled by electric contacts operated by a feeler 20. From the front feed rollers the overlapped sheets are advanced by a conveyer e, Fig. 1, or by inclined rollers 28, Fig. 6, and means for blowing air under the sheets in the pile a, and between the sheets of the overlapped stream are provided.

Abstract: A latex composition for the making of rubber roads, sidewalks, floors and other surfacings consists of latex, sulphur or other vulcanising agent, one or more accelerators, one or more fillers other than lime and approximately 1 to 2 per cent by weight of lime or other equivalent flocculating agent, calculated on the dry rubber content of the latex, which will permit the surface to dry out evenly without the formation of contraction cracks.  A suitable composition for a road comprises a dry mix of 60-64 lbs. kaolin; 32-36 lbs. powdered carbon; 1.5-2 lbs. sulphur; 2-2.25 lbs. zinc oxide and 0.25-0.5 lb. slaked lime of which 14 lbs. are stirred into 1 gallon of rubber latex containing 3.5 lbs. dry rubber to which has been added an accelerator known as "Lat. 2" in the proportion of 0.5 to 1.5 per cent of the weight of the dry rubber content of the latex.  Air should preferably be excluded during mixing, which may be done in a colloid mill, preferably of p  the revolving plate type.  When the last portion of dry mix is added, the rubber "mortar" flocculates. The mixture may be preserved by the addition of casein or thymol and put up into drums, and it may be concentrated by removal of water, e.g. by heating or centrifuging.  The concentrated mixture is diluted before use.  Latices of gutta-percha, balata or concentrated latex such as that known under the Registered Trade Mark "Revertex" may also be employed, in the latter case a suitable composition consists of 17 lbs. dry mix to one gallon of "Revertex" containing 4.25 lbs. dry rubber/gallon.  A suitable method of applying the composition to form surfacings, such as roads, and of preparing the under-surface is described in Specification 406,222.

Title: Process for the recovery of lower carboxylic acids from the product of the liquid phase oxidation of paraffinic hydrocarbons
Inventor: NAKAMURA TAKEO
IPC: C07C51/31
Filed: 1964-03-12
Abstract: Fatty acids having 1-4 carbon atoms are made by oxidizing paraffinic, naphthenic or paraffinic-naphthenic hydrocarbons having boiling points below 200 DEG  C. in the liquid phase with molecular oxygen or an oxygen-containing gas to give a product comprising (a) non-acidic materials capable of being distilled out below 99 DEG  C. in the presence of water (light fractions), (b) water, (c) fatty acids having 1-4 carbon atoms, and (d) oxidates having boiling points above 170 DEG  C. (high boiling point residues) and removing the high-boiling point residues from the oxidized product by distillation, feeding the remaining oxidized product into a distilling device and recycling the light fractions separated therein as the entrainer for the water in an amount such that the water in the oxidized product forms an azeotrope with the light fractions and distilling out the light fractions and the water whereby the lower fatty acids are recovered.  If desired, the light fractions can be removed by distillation from the oxidation product before the high boiling-point residues are separated by distillation.  Alternatively, the non-acidic materials boiling below 60 DEG  C. (acetone fractions) may be removed prior to separation of the high boiling-point residues and the purification completed using the middle fractions (light fractions containing no acetone fractions) as the water entrainer. The high boiling-point residues, light fractions and/or middle fractions can be recycled to the oxidation stage.  The examples, which relate to the isolation of formic and acetic acid, are illustrated by reference to drawings (not shown) showing a distillation scheme.

Filed: 1945-04-27
Abstract: 618,229. Valve generating circuits. LYNCH, A. C. April 27, 1945, No. 10577. [Class 40 (vi)] A thermionic valve oscillator comprises a tuned circuit connected to a driving circuit which is so operated as to produce a square potential waveform. The tuned circuit 3, 4 is connected by the resistance 2 to the output terminals of the amplifier 1, whose input is derived from the capacity or resistance potentiometer 5, 6. The amplifier 1 may be of known type, the gain being at least five times that necessary to produce oscillations, so that the output valve is overloaded and produces square waves. This action may be increased by the use of positive grid bias, in which case the oscillator may be arranged to be non-self-starting and used to indicate the arrival of a signal or the interruption of its power supply. Alternatively, diode or other limiters of known type may be employed, or gas-filled valves, or the output stage of the amplifier may comprise a trigger circuit of known type. In a modified arrangement (Fig. 2, not shown), a saw-tooth waveform is produced by the connection of an R.C. circuit across the amplifier output terminals.
