Title: Process for preventing the evolution of disagreeable smelling gases in the viscose artificial silk manufacture
IPC: D01F2/06
Filed: 1929-07-20
Abstract: 316,971. British Enka Artificial Silk Co., Ltd., (Assignees of Naamlooze Vennootschap Nederlandsche Kuntstzijdefabriek). Aug. 7, 1928, [Convention date]. Cellulose xanthates. - In the manufacture of artificial silk from viscose, an alkali metal nitrite is added to or produced in the viscose or the lye used for dissolving the cellulose xanthate, whereby the evolution of noxious gases is prevented. Since the addition of large amounts of nitrite affects the spinning process adversely, it is preferred to add a relatively small amount of nitrite and to supplement its action by introducing nitrogen oxides from another source into the air-discharge pipes; for instance, nitrogen oxides may be generated in the air-discharge pipes by means of an electric arc.

Patent GB-1304077-A (GB)
IPC: C08J7/043
Filed: 1970-05-11
Abstract: 1304077 Coating BOSTIK Ltd 11 May 1970 [12 May 1969] 22601/70 Heading B2E Substrates having a low critical surface tension of wetting and comprising polymeric material, polymer molecules of which have at least one hydrogen atom on a carbon chain of a repeating unit of the polymer molecule, are treated with ultra-violet radiation whilst photo-sensitizer material is present on the surface and an organic silicon compound applied to the surface to render the surface receptive to coatings. The term "low critical surface tension of wetting" is defined as up to 35 dynes per centimetre as determined by contact angle measurements. Polymeric materials mentioned are polyethylene, polypropylene, copolymers of ethylene and propylene alone or with a low percentage of a non-conjugated diene, e.g. a terpolymer of 64% ethylene, 34% propylene and 2% 1, 4-hexadiene, and fluorinecontaining polymers such as polyvinyl fluoride and polyvinylidene fluoride. Other surfaces which may be treated are moulded bodies of normally wettable resins, e.g. polyamides and polyesters which may contain residual amounts of mould release agents. The photo-sensitizer may be methylene chloride, trichloroethylene, chloroform, benzophenone, acetophenone, benzoin, 2-acetonaphthone, acenaphthene, fluorene. The photo-sensitizer may be applied to the surface of a substrate as a solution in a volatile solvent or as a liquid, or by melting and spraying fusible solid photo-sensitizer or by dusting on a powder of the photo-sensitizer. Alternatively, the photo-sensitizers may be uniformly distributed in the polymeric material of the substrate by milling it into the polymer prior to forming the substrate. When solid photo-sensitizers are used heat sufficient to fuse the photo-sensitizer may be applied. Excess photo-sensitizer may be removed from the surface after radiation, e.g. by wiping the surface with a solvent of the photo-sensitizer. Preferred organic silicon compounds are silanes having one or more alkoxy, aryloxy, acyloxy, amino or vinyl groups, applied as a liquid or as a solution, e.g. by spreading and wiping off the excess. The organic silicon compound may be present on the surface at the time of radiation, e.g. as a solution in a solvent which is itself a photo-sensitizer, e.g. ethylene dichloride. The solvent for the silane may contain water which converts the silane to the silanol. The treated substrates may be coated with epoxy, acrylic, nitrocellulose and oil-based paints, adhesives, e.g. epoxy resin and polyamides.

Abstract: 424,340. Printing-machines. QUICK, C. G., BALL, D. A., and WHITEHEAD, W. A., 109, Borough Road, London. Aug. 16, 1933, No. 22909. [Classes 100 (i) and 100 (ii)] A rotary printing-press for producing different kinds of products comprises a number of printing couples, one at least of which is capable of being driven either at half or at full speed, and a kite device associated with this couple to enable a web to be printed on one side at one end of the couple and perfected at the other end, the full speed webs being severed into product lengths and the half speed webs being severed into insert-sheet lengths, the insert sheets having a transverse line of paste applied thereto and being speeded up before insertion in the main products. The main printing couples 1-4, Fig. 1, are arranged in pairs to print on both sides of double-width webs, and each has two plates around and two plates along the cylinder with the matter to be printed in " column along " formation. The couple 5 which can be run at full speed, but normally runs at half speed, perfects a single-width web by printing on one side at one end of the couple, running the web over a triangular kite 13 and then printing the other side at the other end of the couple. From the printing-couples, the full-speed webs pass to slitters 17 and turning-bars 18, and the singlewidth webs formed therefrom are associated at rollers 31, Fig. 2. Product lengths are cut therefrom by cutters on rollers 19, 20, and the roller 20 also carries tumblers coacting with jaws on endless chains passing over the roller 19 to fold the products transversely and carry them to a longitudinal folder 21. The halfspeed web passes over a turner-bar 18 to mechanism 23-28 which cuts it into insert lengths and applies a transverse line of paste to the trailing end of the insert sheet. The insert sheets are then transferred to a speeding- up mechanism 29 as described in Specification 390,814 and are associated on the cylinder 20 with the full-speed products. The position of the insert-sheet within the final product can be varied by running some of the full-speed webs around guiding-rollers 30 instead of through the rollers 31. By using the couples separately or in different combinations, various kinds of products can be produced. Specifications 16607 /93, 15356/01, and 20296 /06, [all in Class 100], also are referred to.

Abstract: 381,282. Vehicle opening tops. PYTCHLEY AUTOCAR CO., Ltd. and MOBBS, R. 0., 201, Great Portland Street, London. Aug. 13, 1931, No. 22917. [Class 108 (i).] The sliding panels of vehicle opening roofs are adapted to be held securely in any desired position by means of a pair of plates or fingers at each side of the panel adapted to grip a fixed rail on its opposite faces. As shown, the fingers 40, 42 pivoted at 48 are mounted on a block 34 carried by a transverse tubular member 22 in such a way that a slight rotary movement of the tube 22 causes the fingers 40, 42 to open and close to release and grip respectively the flange 52 of the panel guides. Rotary movement is given to the tube 22 by means of a screwed stud 26, the end of which is caused to bear on a plate 24 passing through a slot in the tube 22 and bearing against a spring 30 at its other end. The end of the plate 24 may be hooked to engage with a projection 29 on the fixed cross rail to keep the panel closed. In order to ensure that each pair of fingers will grip its related bar 52 the tube 22 may be provided with an axial slot so as to permit a slight further rotation of one end after the other has been stopped by the gripping of the fingers. The block 34 in this case is carried by bars 60 disposed in the said slots, the bars being adjustable to vary the distance between the pairs of fingers on opposite sides.

Title: Production of butadiene
IPC: C07C5/333
Filed: 1947-08-19
Abstract: 2 (iii) Butadiene is produced by catalytically de hydrogenating n-butane to n-butene and buta diene in a first reaction zone, the yield of buta diene being about 10-30 per cent by volume of the n-butane, separating n-butene from the products, catalytically dehydrogenating it to butadiene in a second reaction zone, and recovering butadiene formed in both zones.  Catalysts such as Cr, V or Mo oxide on alumina, desirably with Mg or Zn oxide, are suitable. For the second stage, alumina with minor amounts of Ba and K oxides or magnesia with minor amounts of Fe, Cu, and K oxides are effective, especially when steam is added to the charge.  Temperatures of 565-675 DEG  C., abso lute pressures of 0.05-0.5 atmos., and space velocities of 200-1000 vols./vol./hour in the first stage, or 200-2000 in the second, are suitable.  Products of the first stage pass to a separation zone where light gases, butenes, and butadiene are separated from unconverted butane as by fractionation, solvent extraction and azeotropic distillation.  Butane is re cycled, butenes passed to the second dehydro genation zone, and butadiene, together with that formed in said second zone, collected.  Steam may be added to the second zone to give a total pressure of 0.25-3.5 atmos. above atmospheric.  If the original charge is olefinic, it may be introduced into the separation zone.  Iso-hydrocarbons formed are separated in this zone and removed.  Fluid, fixed or moving catalyst type of operation may be used, and carbon deposits burnt off as necessary. p
