IPC: A44B19/54
Filed: 1955-11-04
Abstract: 826,403. Sliding clasp fasteners. PRYM, H., and PRYM, A. Nov. 4, 1955 [Nov. 4, 1954], No. 31663/55. Class 44 A sliding clasp fastener comprises two stringers each including a tape and a row of interlocking elements, the interlocking elements of at least one of the stringers being formed by portions of the thread or one of the threads from which the tape is plaited, knitted or woven, projecting from the stringer edge in spaced apart relationship. As shown in Fig. 1, the interlocking elements 24 are formed by the weft thread of each tape but in a modification, they can be formed from portions of one of the warp threads. They can also be formed from a weft thread which extends over only part of the width of the stringer. The interlocking elements can be provided with knots or thickenings of any desired shape by stamping, pressing or other hot or cold shaping methods. The marginal warp threads can also be arranged to provide a thread like thickening or other guide means for the slider. In the construction shown in Fig 4, each stringer is made of two woven tapes 50, 51. The tape 50 is of ladder-like construction and is made by omitting the centre warp threads. The tape 50 is folded round the edge of the tape 51 and is fastened to it by sewing or glueing; the centre portions 49 of the weft thread thus form the interlocking elements and the edges 52 of the tape 50 act as guides for the slider.

Title: Improvements in or relating to a method of lowering the tendency towards setting of ammonium sulphate and ammonium sulphate of free-flowing form with a reduced tendency to setting
IPC: C01C1/248
Filed: 1948-12-08
Abstract: The tendency to caking or setting of ammonium sulphate crystals is reduced by distributing over the surfaces of the crystals a deposit of a dyestuff of sulphonated aromatic character such that when the dyestuff is dissolved in a hot saturated aqueous solution of ammonium sulphate and the resulting solution is cooled to incipient crystallization, the ammonium sulphate crystallizes in the form of thin fragile crystals.  The dyestuff, e.g. in amount of 0.001 to 0.1 parts per 100 parts of ammonium sulphate, may be added to a saturated aqueous solution of ammonium sulphate and the latter crystallized by cooling, or ground ammonium sulphate may be mixed with water containing the dyestuff and the water evaporated from the uniformly dye-covered crystals, or ammonium sulphate crystals, the form of which may be modified by crystallizing in the presence of aluminium sulphate, may, in their wet state from crystallization, be sprayed with a solution of the dyestuff and passed to a rotary drier. Dyestuffs specified are: Naphthol Green BNS, Fast Yellow, Naphthalene Fast Orange, Azofuchsine G, Ponceau 6R, Chromazol Yellow, Chlorazol Skye Blue, Fast light Yellow, Lissamine Fast Yellow, Disulphine Blue V, Disulphine Blue AS, Xylene Cyanol FF, Brilliant Cochineal, Bordeaux, Crystal Ponceau, Carmoisine WS and LS, Naphthalene Red EAS, Bismarck Brown, Hydrazine Yellow SO, Eriochrome Red, Acid Green G, M and GG Extra, Erioglaucine Extra, Fast Acid Violet 10B, Acid Violet 4BNS, Edicol Amaranth and Tartrazine, the last two being particularly suitable.

Title: Formation of electorstatic charge patterns
IPC: G03G15/054
Filed: 1973-07-05
Abstract: 1448986 Electrostatic imaging AGFA-GEVAERT 28 Nov 1973 [1 Dec 1972 5 July 1973] 55693/72 and 32007/73 Heading G2H In a method of forming an electrostatic image from a discharge pattern of electrons or positive ions generated in an envelope comprising a target towards which the electrons or ions are directed the surface of a dielectric material constituting or in contact with the target (which surface is outside the envelope) is in an electrostatically charged condition with a charge of appoule sign to the electrons or ions so that an electrostatic image of the pattern striking the target is formed on said surface. As shown, Fig. 6, the discharge pattern is formed by impinging a pattern of electromagnetic radiation 3 on a photocathode 1. The photoelectrons produced are accelerated towards an electron multiplying device 4 by a potential applied between transparent electrode 19 and a conducting layer 8 forming the input layer of the electron multiplying narrow passage device 4. A further potential is applied between the conducting layer 8 and a further conducting layer 10 constituting an outlet layer of said device 4. The intensified electron pattern impinges on a target constituted by two photo-conducting layers 5 and 20 of differing spectral sensitivity. The layer 20 is subjected to corona discharge from wires 21 acting through a conducting grid 24. In an alternative embodiment the grid may be coated with a photo-conductive material. Following the formation of the image on layer 20 the charge on layer 5 may be removed by closing switch 26 and exposing the layer to the type of radiation which will render it conductive. Simultaneously layer 20 may be developed and transferred to a copy sheet. Residual charges on layer 20 may be removed by closing switch 27 and irradiating. In a further form the original pattern may be an x-ray pattern which is impinged on a gas such as xenon which produces photo-electrons and ions. Alternatively x-rays may be impinged on a fluorescent coating incorporating U.V. or visible light emitting substances the light so produced being impinged on a photocathode. The device 4 and the target are enclosed in an evacuated envelope, Fig. 5 (not shown). The discharge pattern may be an information-wire modulated electron beam.

Title: Improvements in or relating to purification of ethanol by distillation
IPC: C07C29/84
Filed: 1949-12-16
Abstract: <PICT:0670229/III/1> Crude ethanol containing n-propanol and other organic contaminants normally boiling between 20 DEG  and 150 DEG C., is purified by feeding it into the side of a fractionating column and introducing water into the column above the feed-point of the crude alcohol, to produce an internal liquid reflux containing 95 to 99 mol per cent of water.  The other operating conditions in the column are maintained so that the n-propanol and all the other contaminants, except methanol and organic acids (if present in the crude) pass overhead, while a dilute aqueous solution of purified ethanol is withdrawn as bottoms.  The dilute aqueous solution of ethanol is concentrated, and if necessary freed from methanol and organic acids, by simple rectification.  Crude ethanol (boiling-range 69-82 DEG C.) containing n-propanol (25 per cent), methanol (0.6 per cent) and other neutral contaminants is fed through line 2 into column 1 which contains sixty plates; and water is introduced into the column through line 4 so as to produce the internal reflux referred to above.  The overhead vapours, which contain the n-propanol and the other contaminants (except methanol) are condensed.  The reflux ratio is 20 : 1 so that 20 parts of the condensate is returned through line 8 to the column, and the remaining part is discharged through line 9. The aqueous bottoms withdrawn from the base of column 1 contain the methanol.  These bottoms are passed to reboiler 13; and that portion not vaporized and returned to column 1 through line 14, is passed through line 15 to column 16.  A side-stream is withdrawn through line 24 from column 16, and is passed to reboiler 25.  Methanol is stripped from the side-stream in reboiler 25, and is returned to column 16 through line 26.  Pure ethanol (96 per cent) is withdrawn from the base of reboiler 25; and is partly withdrawn from the system as product through line 29, and partly returned to column 16 through line 28.  Part of the overhead condensate from column 16 is returned as reflux through line 22, and part is withdrawn from the system through line 23.  Water is withdrawn from the base of column 16, and part thereof is recycled to column 1 via lines 35 and 4.  The water supplied to the upper part of column 1 may contain various salts or acids which do not interfere with recovery of pure ethanol by azeotropic distillation. Specification 647,903 is referred to.
