Patent GB-486866-A (GB)
Title: Manufacture of artificial filaments or similar materials
IPC: D01F2/04
Filed: 1936-12-10
Abstract: Liquid residues obtained in the production of alcohols or conversion products thereof by catalytic methods involving the reaction of oxides of carbon with hydrogen or substances yielding hydrogen, which have undergone a deep seated change by hydrogenation, preferably catalytic hydrogenation, and which boil between 140 and 350 DEG  C., are added to viscose which is then formed into artificial filaments or similar materials having a matt lustre.  By the hydrogenation practically all aldehydes and ketones in the residues are converted into alcohols and double linkages are saturated.  Artificial silk of a lustre similar to that of natural silk may be obtained.  As addition to the viscose, hydrogenation products of the high boiling portions obtained in the synthesis of methanol or in the syntheses described in Specifications 229,714, 238,319, and 254,819, [all in Class 2 (iii)], may be used.  The residues may be fractionated before hydrogenation, the fractions suitable for the process may then be hydrogenated and used as a whole or after a subsequent fractionation. Individual substances such as secondary or branched chain alcohols may be isolated from the residues before or after the hydrogenation, and may subsequently be added to the viscose.  The substance to be added may be treated with alkali lye or may be subjected to steam distillation before or after hydrogenation.  In an example, the fraction boiling at 160-220 DEG  C. of the condensate obtained in the catalytic reduction of carbon monoxide by hydrogen is treated with alkali lye and then hydrogenized catalytically at 200 atmospheres pressure.  The product is subjected to distillation in steam to expel 10 per cent of first runnings.  The product is mixed with viscose from which mat artificial silk is obtained.  In another example, the fraction boiling at 120-220 DEG  C. of the condensate obtained in the catalytic reduction of carbon monoxide is hydrogenized catalytically under pressure, and the portion of the product which boils at 180-200 DEG  C. is added to viscose.  In another example, a mixture of residues from the catalytic reduction of carbon monoxide is subjected to catalytic hydrogenation and the product which boils at 240-300 DEG C. is added to viscose or to the crude material used for making the viscose.

Title: Improvements in or relating to sound-damping and heat-insulating walls
IPC: E04B2/74

Abstract: 733,306. Partition walls. KOLLER, E. Dec. 8, 1953 [Jan. 12, 1953], No. 34154/53. Class 20 (4). A double sound- and heat-insulating partition wall is formed of prefabricated panels, the oppositely situated slabs 8, 9 or 10, 11, Fig. 2, of which are arranged and constructed to have different bending strengths by choice of spacers, the kind, or thickness, of material &c., the natural vibration wavelength of each panel being so selected that air-borne sound passing through the wall is considerably attenuated. Each panel is formed of two slabs 8, 9 or 10, 11 cemented to spacers 12, made e.g. of rubber, and having different thickness and material properties, the slabs 9, 11 being made e.g. of sheet metal and the slabs 8, 10 being made of plastic, fibre board, or eternite. When a slab is made of plastic, or fibre board, a thin sheet of non-porous material, e.g. sheet metal, should be mounted about 1-3 mm. away from it to obtain good sound-deadening effect. The space between the slabs is filled with sound-deadening material, e.g. crumpled paper or glass wool 13. The vertical edges of the panels are cemented to column strips 4 or 5 made e.g. of metal, plastic or eternite, and which, upon erecting the panels side by side, are joined in nesting relation, 180 degrees with respect to each other, to form a rigid hollow column. The columns and the wall panels are secured between the floor and ceiling by clamping or gluing or similar known manner, and are closed off by cover strips 19, Figs. 3, 4. The panel according to Fig. 3 is closed along its lower edge by a strip 14 screwed to wooden strips 17, 17 joined to the slabs 8, 9 by screws 18 which also fasten the cover strip 19, flexible packing strips 20 being arranged between the lower edges of the slabs 8, 9 and the strips 19. The panel according to Fig. 4 has two sheet steel slabs 21, 22 which are bent round and secured to wooden strips 23, 24 respectively, a flexible packing strip 20 being inserted between the lower edge of the slab 22 and the cover strip 19 secured to it. A V- shaped groove 28 is formed in the strip 23 to receive a flexible packing strip 27. A double wall partition is installed by first setting up an auxiliary column, not shown, at a chosen place in the space intended to be occupied by a hollow column 4, 5, the auxiliary column, e.g. a pipe being braced between the floor and ceiling, e.g. by rubber pads, and being provided with lugs, or recesses, to facilitate the joining of the strips 4, 5. The other strips 4, 5 of adjacent panels are arranged together either with, or without, locating auxiliary columns between them, as desired. The auxiliary columns can be so constructed to accommodate window, or door, frame parts.

Photographic images are prepared by imagewise exposing a substantially unhardened (as defined) light-sensitive silver halide-hydrophilic colloid emulsion layer containing a sulphur dioxide adduct (as defined) of a tanning developing agent, developing the image formed with an aqueous alkaline solution and contacting the developed layer with a receiving sheet in the presence of moisture to transfer a stratum of colloid from the less exposed areas of the emulsion layer to the receiving sheet to produce a visible image thereon. The sulphur dioxide adducts, which are dissolved by the aqueous alkaline solution during development, may be in the light-sensitive emulsion layer or a hydrophilic colloid layer thereunder; the adduct may be derived from catechol, catechol carbonate, toluhydroquinone, a mixture of N-methyl-p-aminophenol sulphate and hydroquinone, a mixture of 1-phenyl-4, 4-dimethyl-3-pyrazolidone and hydroquinone, chlorohydroquinone, pyragallol monocarbonate, nordihydroguairetic acid or gentisic acid.

Title: Production of alkoxymethyl acetates
Inventor: YEOMANS BERTRAM
Filed: 1957-11-07
Abstract: Alkoxymethyl acetates are prepared by heating acetic anhydride with dialkoxy-methanes having at least 4 carbon atoms in the molecule under substantially anhydrous conditions in the presence of an acidic catalyst in a proportion of 0.1 to 1.0% by weight based on the total weight of the acetic anhydride and dialkoxymethane, and recovering the alkoxymethyl acetates by fractional distillation.  Alkyl acetates are formed simultaneously.  Specified dialkoxymethanes are diethoxy- and di-n-butoxymethane.  Reaction is conveniently effected at the boiling-point of the mixture under reflux.  The reaction mixture may be freed from the catalyst by flash distillation prior to the fractional distillation.  It is preferred to use an excess of whichever reactant is most easily separated from the product by distillation.

Abstract: 301,392. Heberlein & Co. Akt.-Ges. Nov. 28, 1927, [Convention date]. Fibre, treating. - Vegetable fibrous material and loose vegetable fibres are treated successively with two or more different swelling-agents, the swelling operation not being interrupted by means causing intermediate coagulation between the treatments. The material may be treated with alternate baths of different concentrated inorganic acids, with alkaline lyes alternating with ammoniacal copper oxide solution, or with salt solutions such as zinc chloride or calcium sulphocyanide combined with each other or with acid or alkaline swelling agents. The excess of swelling-agent is removed between treatments by pressing, wringing or centrifuging. Where the reagent, such as an alkaline swelling-agent, applied during one treatment would react with the next reagent such as an acid, the first reagent is removed by washing with an indifferent solvent which does not cause coagulation before the application of the next swelling-agent. The treatment renders the material woolly and soft, stiff and transparent, or in some case linen-like with or without lustre, while further effects may be produced by treating one, side only of the material. Pattern effects may be produced by applying the treatment to parts only of the material by printing, spraying, or painting with or without the use of thickeners, or by reserve printing. The process may be combined with the process described in Specification 268,389. Specifications 13129/14, 100,483, [both in Class 42 (i), Fabrics, Finishing &c.], and 108,671 also are referred to.
