Title: Method and apparatus for forming blown tubular films
IPC: B29C48/10
Filed: 1962-07-03
Abstract: 1,006,573. Tubular films. NATIONAL DISTILLERS & CHEMICAL CORPORATION. July 3, 1962 [July 5, 1961], No.25508/62. Heading B5B. A die-formed, gas-filled tubular film of molten thermoplastic material is drawn through a Venturi throat, through which, simultaneously and concurrently, a high velocity stream of gaseous heat-exchange medium is passed, so as to cool the film and to maintain the pressure on the space around the film lower than the pressure within the film on its entry to the throat, whereby the film expands and sets on its passage through the throat. As the molten film expands, the pressures inside and outside the film are substantially equalised. Preferably the molten material is discharged from the die into a zone of sub-atmospheric pressure, while the pressure inside the film is at least atmospheric. The heat-exchange medium, e.g. air, may be refrigerated or selfrefrigerating upon expansion in passage through the Venturi. In one embodiment (Fig. 1), extrusion die 11 is spaced by element 19 from a plenum chamber formed by annular walls 12, 13 and cylindrical wall 14, the latter being provided with inlets 15, 16 for tangential introduction of pressurized air. Cylindrical baffles 17, 18 smooth and distribute air flow inside the chamber. Annular plate 21 supports Venturi throat 20, the plate and throat being adjustable, relative to inner periphery of wall 13, by screws 22. The pressure inside the film is induced by feeding gas therein from conduit 11a and is maintained in the film by nip rolls. The action of high velocity gas passing through the Venturi induces a zone of reduced pressure on the Venturi extending from the flared end 20a thereof. As the film expands, the area of the annular space between it and the inner surface of the throat is reduced, and the pressures inside and outside the film are equalized, thus stabilizing the diameter of the tubular film. The final diameter of the tubular film may thus be determined by controlling the flow rate and velocity of gas discharged from the plenum chamber. In further embodiments (not shown), the Venturi throat, instead of projecting into the plenum chamber, is mounted on the upper annular plate of the plenum chamber, or the plenum chamber and the Venturi throat may form an integral structure.

Title: Process for the manufacture of regenerated cellulose structures from viscose
IPC: D01F2/10
Filed: 1953-09-16
Abstract: Regenerated cellulose structures, e.g. artificial threads, bands, films and sponges, are made from viscose which contains such a quantity of a dithiocarbamate substituted on the nitrogen atom by one or more aliphatic or cycloaliphatic radicals, and containing at least 12 carbon atoms per molecule, as is equivalent to 1-5 per cent by weight (calculated on dry cellulose) of the primary or secondary amine from which the dithiocarbamate is derived.  The dithiocarbamate may be added during the manufacture of the viscose, and advantageously it may be formed in situ by adding the primary or secondary aliphatic or cycloaliphatic amines having the necessary number of carbon atoms (from which the dithiocarbamates are prepared by reaction with carbon disulphide, preferably in the presence of caustic alkalies) to the alkali cellulose or to the viscose containing free carbon disulphide and alkali.  Specified amines are n-undecyl-, sec.-undecyl-, dodecyl-, tridecyl-, tetradecyl-, pentadecyl-, hexadecyl-, octadecyl-, di - n - hexyl-, di - n - heptyl-, di - n - octyl-, di-n-dodecyl-, dimiricyl-, di-(sec.-octyl)- and di-cyclohexyl-amines.  The dithiocarbamates improve the spinnability of the viscose, and they or the amines re-formed therefrom in the acid precipitation bath serve to increase the stretch-ability of regenerated cellulose threads formed from the viscose.  They also impart softness, a matt lustre, an increased strength and an increased resistance to hydrolysis and bacterial influences to the regenerated cellulose products.

Title: Improvements in or relating to the manufacture of sulphuric acid esters of leuco derivatives of vat dyestuffs
IPC: C09B9/00
Filed: 1932-09-21
Abstract: Leuco derivatives of vat-dyes, esters of.--A vat-dye is reduced to its leuco compound by means of carbon bisulphide in the presence of a tertiary organic base and of ammonia and/or a primary aliphatic or hydroaromatic amine, and without isolation the reaction product is esterified by adding sulphur trioxide or an agent containing sulphur trioxide or capable of yielding it under the conditions of working, the entire process being performed under substantially anhydrous conditions and in the absence of free oxygen.  Suitable tertiary bases are pyridine or its homologues, quinoline, hexahydrodimethylaniline, and suitable amines are methyl-, ethyl-, and butylamine, hexahydroaniline and tetrahydronaphthylamines.  An inert organic diluent may also be present, such as chlorbenzene or o-dichlorbenzene, and reduction occurs at normal or even lower temperatures; in some cases the addition of sulphur, in others the addition of aliphatic or hydroaromatic secondary amines, is advantageous.  Esterifying agents include chlorsulphonic acid and esters or sodium salt, and fuming sulphuric acid; they are used at temperatures between 10--70 DEG  C. and by subsequently adding an alkali metal salt, a stable water-soluble ester salt is obtained.  In examples: (1) 5.7 : 5<1>.7<1>-tetrabromindigo is reduced in pyridine by carbon disulphide and ammonia in a current of nitrogen and the mixture esterified by chlorsulphonic acid in pyridine, from which the sodium salt of the ester is obtained in the usual manner; instead of ammonia n-butylamine may be employed; by the same process the sulphuric esters of 6.6<1>-diethoxyindigo, 2-(4-chlornaphthalene) -2<1>-(4<1>-methyl-5<1>-chloro-7<1>-methoxyindol) - indigo, 3.4.8.9 - dibenzpyrene - quinone, and the alkali-condensed 1-(Bzl-benzanthronylamino) - anthraquinone dye (Specification 24604/08, [Class 2]); (2) 7.7<1>-dinitrothioindigo is reduced in pyridine with carbon disulphide and anhydrous ammonia and the product esterified by the methyl ester of chlorsulphonic acid in pyridine; by reduction in an alkaline medium the corresponding 7.7<1>-diamino derivative is obtained; (3) 4.4<1>-dimethyl-5.7.6<1>-trichlorothioindigo in presence of some piperidine is reduced by ammonia and carbon disulphide in pyridine, and the leuco sulphuric ester obtained from the product as above; the piperidine accelerates reduction.  Specification 186,057, [Class 2 (iii)], also is referred to.
