Patent GB-740584-A (GB)
Title: Improvements in or relating to the production of filamentary material by melt spinning
IPC: D01D1/04
Filed: 1953-08-18
Abstract: <PICT:0740584/IV(a)/1> <PICT:0740584/IV(a)/2> A moving band of a thermoplastic filament-forming material having two opposing faces wider than the other two is melted in a passageway of cross-section similar in size and shape to that of the band, all or nearly all the heat needed for melting being supplied through the wider faces of the band.  The molten material may be fed to a spinning jet so that filaments, yarns, ribbons or the like may be obtained in a continuous operation.  The molten material may be forced through the spinning orifices by the pressure applied to the incoming band, this pressure being transmitted through the band to the molten material.  The band thus acts as a continuously renewed piston, pushing the molten material before it.  The filament-forming material may be a polyamide, polysulphonamide, polyurethane or polytriazole.  The wider walls of the passageway may be heated to a temperature which, preferably over substantially the whole length of the passageway, is above the melting-point of the filament-forming material, and the narrower walls may be maintained at about the same temperature as the narrower faces of the band at the same point, as by means of a cooling fluid, so that little or no heat transfer occurs between the narrower walls of the passageway and the narrower faces of the band in contact with them.  This method of melting removes the tendency for the band to jam in the passageway.  The band preferably is of rectangular cross-section and has a width at least twice its thickness.  As shown in Figs. 1 and 2, feed rollers 2, 3 grip a band of filamentforming material emerging from guide 1 and feed it through guide 4 into a passage 5 in a melting tube 6.  The surface of one or both of the feed rollers may be serrated, knurled or toothed so as to prevent slippage of the band, and the rollers may be spring-pressed towards each other.  The passage 5 has a cross-section of substantially the same size and shape as that of the band. Electric heating coils 7 are provided adjacent to and along the length of the wider walls 8 of the passage 5.  The coils may be individually controlled.  Adjacent to the narrower walls 9 of the passage 5 are cooling tubes 10 having inlets 11 and outlets 12 for cooling fluid such as oil.  The material of the band melts as it passes through tube 6 and the molten material collects in a well 15.  It is forced through the well by the pressure exerted by the band, then through a sand pack 17 and filter screen 18, and finally through the orifices in the spinning jet 20 which form it into filaments.  The outer surface of the spinning jet may be given a high polish to reduce the amount of heat radiated to the filaments from the surface of the jet and to conserve the heat in the mass of molten material in the well 15.  Thermocouples 24 are provided along the length of the melting tube to measure the temperature.

Title: Azo dye pattern sheet
IPC: G03F1/54
Filed: 1975-05-23
Abstract: 1484080 Azo dye pattern sheets for making masters W H BRADY CO 23 May 1975 [28 May 1974] 22902/75 Headings G2C and G2X A flexible pattern sheet for making printed circuit board masters comprises (i) a flexible, transparent base sheet, (ii) a visibly coloured azo dye layer in which the dye is in an imagewise or overall distribution and (iii) a transparent adhesive layer bonded to either the base sheet or the azo dye layer. The pattern sheet is prepared by coating a base e.g. of polyethylene terephthalate with a transparent colourless resin containing a diazonium compound and an azo coupler, exposing and developing the sheet to produce the azo dye, and coating a layer of adhesive e.g. a pressure sensitive adhesive on the resin layer or on the rear surface of the base. The pattern sheets are adhered to transparent sheets to make master transparencies, which are then photographically reduced to form photomasks for printed circuits. Two circuits for opposite sides of a printed circuit board can be mounted on a single master transparency by using two sets of pattern sheets, each set having an azo dye which absorbs and transmits light in wavelength regions completely distinct from those of the other set. The circuits are then photographed separately using different filters.

Title: Improvements in process for the production of aminocarboxylic acids and their n-substituted derivatives
IPC: C07C237/00
Filed: 1952-09-15
Abstract: Amino carboxylic acids and their N-substituted derivatives in which a hydrogen of the amino group is substituted by an acyl group are produced by reacting lactones of the formula <FORM:0728970/IV (b)/1> (in which R1 is a substituted or unsubstituted carbon chain and X is hydrogen or an alkyl radical) with carboxylic acid amides at elevated temperatures, advantageously with the exclusion of moisture, to give N-substituted aminocarboxylic acids which may be saponified with mineral acids or alkali solutions to give amino carboxylic acids. Lactones containing acylatable groups may be used as starting materials, the acylatable groups being unaffected by the reaction. Alternatively when amino carboxylic acids are required as end products lactones which are substituted by groups which can react with ammonia may be used, e.g. if a lactone substituted by halogen is used an aminocarboxylic acid which still contains halogen is obtained.  The lactones may be reacted with aliphatic, aromatic, alicyclic or heterocyclic acid amides, e.g. formamide, acetamide, propionamide, benzoylamide and the amides of palmitic, stearic and salicylic acids.  In the examples (a) a -amino-g -butyrolactone is reacted with formamide to give the compound of formula H.OC.NH.CH2CH2CHNH2COOH, which is hydrolysed with hydrochloric acid to give the hydrochloride of a -g -diamino butyric acid; and (b) a -bromo-g -butyrolactone is heated with formamide to give <FORM:0728970/IV (b)/2> which is hydrolysed with hydrochloric acid to give the hydrochloride of a -bromo-g -aminobutyric acid.

Title: Process for preparing hard resinous products and hardenable compositions and the resulting hard resinous products
IPC: C08L63/02
Filed: 1952-09-19
Abstract: Mixture of convertible urea-formaldehyde condensation products and of glycidyl ethers of dihydric phenols are hardened by an organic mono-, di- or tri-sulphonic acid, as claimed in the parent Specification, in the form of an amine salt.  The proportion of glycidyl ether to urea-formaldehyde condensate preferably ranges between 9 : 1 and 3 : 7.  The preferred proportion of hardening agent is 0.1-10 per cent. based on the weight of the resins.  The preferred hardening temperature is between 100 DEG C. and 250 DEG C.  The urea-formaldehyde condensate is preferably alkylated, e.g. with n-butanol.  The preferred glycidyl ether is prepared from 2, 2-di(4-hydroxyphenyl)propane.  The amines used for making the salts may be primary, secondary or tertiary, aliphatic or aromatic. Solvents, pigments, fillers and dyes may be present in the compositions.  If desired small amounts of water may be added to assist solution of the amine salt.  In the examples solutions of glycidyl ethers of bisphenol and of butylated urea-formaldelyde condensates are employed.  The solvents employed were generally mixtures of xylene, ethylene glycol monoethyl ether acetate and n-butanol.  Example II employs a mixture of methyl isobutyl ketone, toluene, ethylene glycol monoethyl ether acetate, xylene and n-butanol.  Hardening agents employed are the morpholinium, diethylamine, triethylamine or di-isopropyl amine salt of p-toluene sulphonic acid; the neutral triethylamine salt of m-benzene disulphonic acid; the pyridine salt of p-toluene sulphonic acid; the aniline salt of p-toluene sulphonic acid; the morpholine salt of m-benzene disulphonic acid; the neutral salt of cetyldimethylamine and a mixture of C1-C3 alkane sulphonic acids.  The results of various tests made on films formed from the compositions on steel panels are given.  One example illustrates the use of titanium dioxide to yield an enamel.
