Title: Method of manufacturing a laminated material based on glass-like transparent plastics material
IPC: B29D11/00
Filed: 1975-10-28
Abstract: 1528774 Laminates G S VESNITSKAYA E M GERASIMOVA E F MARKINA J I KNYAZEVA M M GUDIMOV G N PLATONOVA and A V KORJUKIN 28 Oct 1975 44436/75 Heading B5N A laminate is produced by applying on to the surface of a glass-like transparent plastics material, e.g. of polycarbonate or polyacrylate, a semi-transparent first coating of an inorganic substance by thermal evaporation under vacuum, applying a second coating of a colourless inorganic substance semitransparent to visible light over the first coating also by thermal evaporation under vacuum, and by means of an adhesive applying to the glass-like transparent plastics material provided with the two coatings a layer of glass-like transparent plastics material having no such coatings, the second coating being of a material different from that of the first coating and protecting the first coating from the adhesive. Bonding may be effected by applying an adhesive layer of polyvinyl ethylol on to the entire surface of the glass-like transparent plastics material having such coatings and only on to those areas of the glass-like transparent plastics material having such coatings where the inorganic coating is absent, assembling the two sheets of glass with a polyvinylbutyral film therebetween and pressing the assembly in an autoclave at a temperature of 98‹-150‹ C. and pressure of 3-18 atm. The first coating which may be 5-500 nm thick may have light, heat and radio reflecting and electrical conductivity properties and may comprise a metal, metal oxide or metal salt of a mineral acid. The coat obtained by using sulphides or selenides may be subsequently processed in vapours of sulphur or selenium. The second coating which may have a thickness of 50-1000 nm may comprise non- metals, oxides of metals or non-metals or salts of metals and mineral acids. The assembly may be placed into a rubber bag, evacuated and pressed to obtain bonding. In examples polycarbonate glass-like material is coated first with cuprous sulphide and then with lithium fluoride, optionally after treatment with sulphur vapour, and polymethyl methacrylate glass-like material is coated first with aluminium and then with magnesium fluoride or germanium or first with gold and then with silicon dioxide or titanium oxide.

As shown in Fig. 1, frames 2 are set on longitudinal guide members A on a fixed frame 1 within which two longitudinal L-section rails 5 are provided. Nuts 6, Figs. 1 and 6, are secured to the undersides of the horizontal webs of the rails 5 in aligned pairs in threaded engagement with shafts 7, each having two threads of opposite hand to one another, one on each side of a smooth central section to which are secured spaced confronting bevel wheels 8 meshing with a bevel wheel 9 on a longitudinal shaft 10. Rotation of the shaft 10 from an electric motor 14 causes concomitant movement of the rails 5 toward or away from one another. Within the frame 1, above the shaft 10, is a platform 15, Fig. 2, having depending therefrom supports 16 secured to nuts 27 each threaded on a shaft 17 journalled, at the upper end, on a batten 28 and having, at the lower end, a bevel wheel 18 meshing with a bevel wheel 19 fixed on a rotatable shaft 20. Rotation of the shaft 20 from an electric motor 26, Fig. 7, raises or lowers the platform 15. In use, the multiple framing, having its upper edges smeared with glue, is positioned on the frames 2 and a screen cloth has one end thereof fastened to a transverse series of pins at the end of the machine remote from a roller 3 and the other end of the cloth is rolled on the roller 3 which is rotated by a motor 4 until the desired longitudinal cloth tension is reached. The lateral edges of the cloth are impaled on pins on the rails 5 which are moved apart until the desired widthwise tension is reached. The platform 15 is raised so that the framing is brought into contact with, stretches and adheres to the cloth. The individual frames of the framing are separated from one another by the frames 2 and, after the glue has set, the cloth is cut transversely between successive pairs of frames.

[Also in Division C3] The invention comprises organic sulphonic acid metal salts of general formula wherein R 1  is hydrogen or an alkyl group having 1-6 carbon atoms, n has a value from 1-3, r has a value from 0-3 and X is hydrogen or Z, the sulphonated unit or radical of formula wherein R is hydrogen or an alkyl group having 1-6 carbon atoms, and M is an alkali metal, there being at least one X which is a Z unit. The above compounds and other organic sulphonic acid salts may be prepared by heating an alcohol, e.g. of formula (IV) or other appropriate alcohol such as glycerine, phenol, trimethylol ethane, or pentaerythritol, with a sultone of formula wherein R is hydrogen or an alkyl group having 1-6 carbon atoms, e.g. 1,3-propane sultone, 1,3-butane sultone, 1,3-isohexane sultone, 1,3- hexane sultone in the presence of an alkali metal hydroxide, e.g. NaOH, KOH, LiOH, at a temperature of 50-120‹ C. and atmospheric, superatmospheric or sub-atmospheric pressure. The hydroxides may be employed in a large volume of organic medium such as PhH, PhMe, Xylenes to permit azeotropic distillation of the water in the reaction and thus prevent reversing of the reaction. In the compounds containing only one Z unit, e.g. A-Z, A is a monovalent organic radical such as an aliphatic, aromatic, araliphatic hydrocarbon radical or a substituted derivative thereof in which the substituents may be hydroxy, alkyl or alkoxy groups. In the compounds containing more than one Z unit, e.g. B(-Z)m, where m is greater 1; B is an appropriate polyvalent radical and may be an alkylene, arylene or aralkylene radical. The product is used in improving the dyeability of organic filament-forming polymers (see Division C3).
