Title: Process of dyeing polyurethane shaped article with water-soluble dyestuffs
IPC: D06P3/24
Filed: 1962-04-25
Abstract: Shaped articles of polyurethanes, e.g. fibres and foams, are dyed in a bath containing an anionic water-soluble dyestuff and either a cationic surfactant or a mixture of amphoteric surfactant and an acid substance.  Suitable dyes are direct, acid and reactive dyes.  When reactive dyes of the formula <FORM:0989547/D1-D2/1> are used, where R, R1 and R11 are H, lower alkyl or halogen, Z is a poly-basic acid group and D a dye molecule, the dye is dissolved in water, a caustic alkali, sodium carbonate or sodium triphosphate is added to form the sulphone and the resulting solution is neutralized with an acidic material before being used to dye the article.  Suitable cationic surfactants are ammonium salts, alkyl pyridinium halides and alkyl amines. Suitable amphoteric surfactants are those of the betaine type which are used in conjunction with acid substances, e.g. formic, acetic, phosphoric, hydrochloric and sulphuric acids.  The dyebath may further contain a non-ionic surfactant.  Examples are given.

Title: Automatic phasing control for facsimile recorders and the like
Inventor: COOLEY AUSTIN GEORGE
IPC: H04N1/36
Filed: 1959-05-11
Abstract: 859,265. Electric synchronous movements. TIMES FACSIMILE CORPORATION. May 11, 1959, No. 16077/59 Class 40(3). In an automatic apparatus in which a rotatable member is brought into phase correspondence with a remote mechanism under the control of a received phasing impulse, the rotatable member is driven by a synchronous motor which has a rotatable stator. By means of a phasing device which is coupled and uncoupled to the member under control of the impulse, a second motor rotates the stator of the synchronous motor, together with the phasing device, to bring the member to the correct phase. As applied to a facsimile system, a removable drum 11 carries the recording medium and is rotated by a synchronous motor 19. The phasing device comprises plate 25 and pin 26 carried by a sleeve 30 which turns freely on the motor shaft. Under the action of spring 31 pin 26-engages a projection in an annular slot in the end of drum 11 so that the phasing device rotates with the drum. When a phasing impulse is received an electromagnet 33 is energized and withdraws the phasing device from movement with the drum. The position of the device therefore indicates the amount by which the drum 11 is out of phase at that instant. At the same time a motor 23 starts to rotate the stator of motor 19, and with it the electromagnet and the phasing device; the speed of rotation of drum 11 is therefore increased. In the withdrawn position a lug 39 on the phasing device can operate a switch 38, and it does so when the drum is in phase with the remote mechanism. This stops motor 23, and the drum 11 now again rotates at synchronous speed. On the completion of scanning, motor 23 is reversed and the stator of motor 19 returned to a preset position.

Title: Process for the production of nitriles
Filed: 1953-06-11
Abstract: Nitriles are produced from alcohols and ammonia, by contacting the alcohol in vapour phase, in admixture with more than an equimolecular amount of ammonia, with a catalyst which consists substantially of iron and/or iron oxides, at a temperature within the range 300-470 DEG  C.  The catalyst (see Group III) may be supported and its activity is promoted by alkali metal compounds, silicic acid and copper.  The preferred temperature range is 360-420 DEG  C.  The catalyst load varies with the temperature employed, but in general is 25-50 litres of liquip alcohol per 100 litres of catalyst per hour. The process is generally carried out at atmospheric pressure but higher or lower pressures may be used.  The catalyst is preferably reduced with hydrogen, or with the reactants employed for the production of the nitriles, before use.  The catalyst may be packed in vertical tubes with external temperature control, and the preheated reaction mixture passed downward through the catalyst layer.  In examples hexanol gives a C6 nitrile, butanol gives butyronitrile, and a C10 alcohol obtained by hydrogenation of aldehydes obtained in an Oxo synthesis gives a C10 nitrile.ALSO:Catalysts, consisting substantially of iron and/or iron oxides, are used in the production of nitriles from alcohols and ammonia. by contacting the alcohol in vapour phase in admixture with more than an equimolecular amount of ammonia, at a temperature within the range 300-470 DEG  C. (see Group IV (b)).  The catalyst may contain supporting materials such, for example, as kieselguhr, bleaching earths, clays, ceramic masses, pumice and aluminium oxide. The catalyst may be prepared by precipitation from an iron salt solution, or by fusing together or sintering together the components. The unsupported catalysts are preferred.  The catalysts are preferably reduced before use either with hydrogen, or with the reactants employed in the process.  Catalyst promoters used are, 1-5 per cent. of an alkali metal compound, particularly the oxide, up to 30 per cent. of copper and up to 30 per cent. SiO2 (silicic acid). In examples the iron and/or iron oxide catalysts are used admixed with varying proportions of potassium oxide, copper and silicic acid.

Title: Method and apparatus for felting glass fibres
IPC: D04H17/12
Filed: 1941-12-17
Abstract: 554,104. Felting glass fibres. EDWARDS, A. E. Dec. 17, 1941, No. 16285. [Class 42 (ii)] A felt of glass fibres is formed by depositing long glass fibres upon a surface as a mat wherein the fibres are criss-crossed and predominantly parallel with the said surface and then applying a number of short successive relative movements between the outer surfaces to interfelt the fibres with one another throughout the mat. A mat or lap of glass fibres 31, Fig. 1, is formed on a conveyer 30 by allowing molten glass to flow through feeders 22 under the influence of a blast e.g. of steam from nozzles 23 and of a suction chamber 35. Coating materials such as oils or soaps may be supplied through nozzles 40. During formation of the mat the fibres lie substantially parallel to the conveyer 30 and in order to interfelt the fibres to the desired degree binder solution is sprayed thereon through nozzles 43 and the mat passed between coacting belts 45, 46 the upper belt running over drums 50 mounted on a rectangular frame 51 to which is given a limited circular motion in a horizontal plane by means of eccentrics 53. The belt 45 is driven through a chain 63 from the belt 30 and the belt 46 is driven from a motor 65 mounted on the frame 51 which latter is actuated from a motor 61 through gearing 58 and vertical shafts 54a. The space between the belts 45, 46 decreases according to circumstances e.g. from four inches at the feed end to one inch at the discharge end. A number of superposed mats or laps such as 31 may be fed together between endless conveyer members and drenched with binder solution in order to form a composite lap for subsequent treatment. In a modification the mat 31 is treated between a lower conveyer 80, Fig. 5, and an upper series of rollers 83 carried on endless chains 84 the rollers 83 being advanced over the mat at a speed greater than that of the conveyer 80 thus imparting to the mat a progressive wavelike or rolling movement. In a further modification the lap is treated between pairs of co-operating rollers 100, 102, Fig. 8, the lower roller of each pair being ribbed and mounted in stationary bearings while the upper rollers are reciprocated relatively thereto. Adjacent pairs of upper rollers are mounted in end frames or bearing blocks 114 pivoted on central vertical shafts 116 the inner ends of the frames 114 projecting into recesses in a block 124 which is reciprocated by an eccentric.
