Abstract: 722,841. Agglutinated fibrous materials. VIBRADAMP CORPORATION. June 4, 1952 [Jan. 24, 1952], No. 14088/52. Class 140. [Also in Group XXXII] Agglutinated fibrous material suitable for use as a shock-absorber or spring consists of glass fibres most of which are substantially parallel to a given plane whilst those extending at right angles to the plane or nearly so are broken, e.g. by single or repeated compression. The agglutinant for the fibres may be a phenolformaldehyde resin, nylon, polythene, an organo-silicon or polyvinyl resin. Glass fibres, formed by attenuating streams of molten glass emerging from openings 52, Fig. 1, in a container 50 by means of gas-jets 53, are sprayed with adhesive from nozzles 56 as they fall through a chamber 54, and are collected as a mat 57 on a travelling belt 55. A length cut from this mat or as many superposed lengths as are necessary to obtain the thickness required are hot-pressed to give a chosen compression. The bonded glass fibrous material is compressed without heating once or repeatedly to an extent exceeding the compression to which it is to be subjected in use. A spring element, Fig. 6, may be formed from the material.

Title: Process for the manufacture of new disazo dyestuffs
IPC: C09B31/08
Filed: 1947-05-28
Abstract: Disazo dyestuffs are manufactured by diazotizing aminoazo dyestuffs of the general formula <FORM:0623913/IV (c)/1> (wherein x represents an alkyl, alkoxy or acylamino group and Y a hydrogen atom or an alkyl or alkoxy group, and wherein the benzene nuclei A and B may contain further substituents) and coupling with 2-(41-aminobenzoylamino) - 5 - naphthol - 7 - sulphonic acid.  The starting materials may be prepared by diazotizing 4-(41-aminobenzoylamino)-1-hydroxybenzene-2-carboxylic acid or a substitution product thereof and coupling with amines of the benzene series having a free p-position to the amino group and an alkyl, alkoxy or acylamino group as a substituent in m-position to the amino group, and optionally bearing, as a second substituent, an alkyl or alkoxy group in p-position to the first substituent. In some cases it is advantageous to use the o -methanesulphonic acids of these amines, in which case the sulphomethyl group is eliminated after coupling by heating the monoazo dyestuffs with an alkali or a dilute acid.  The diazo dyestuffs dye cotton and regenerated cellulose fibres in red, bordeaux, violet or blue tints, and may be diazotized on the fibre and developed, e.g. with b -naphthol.  The direct and developed dyeings are improved in fastness to light by treatment with anti-crease agents.  Examples describe the use, as diazo components, of the dyestuffs 4-(41-aminobenzoylamino) - 1 - hydroxybenzene - 2-carboxylic acid --> m-toluidine (or its o -methanesulphonic acid, subsequently hydrolysed), 1 - amino - 2 : 5 - dimethylbenzene, 1 - amino - 3 - acetylaminobenzene, m - anisidine, 1 - amino - 2 - methyl - 5 - methoxybenzene or 1-amino-2 : 5-dimethoxybenzene.
