Title: Process for fixing mechanically produced effects on textile fabrics
IPC: D06Q1/08
Filed: 1949-12-09
Abstract: Patterned mechanical effects, such as calendering, glazing, Schreinering and embossing, are fixed on textile fabrics by locally applying, e.g. by printing, to the fabric, on the areas intended to be left plain, an aqueous solution of a salt which readily loses most or all of its solubility on heating but remains capable of neutralizing an alkaline resin-forming catalyst, drying the fabric to insolubilize the salt, impregnating all the fabric with an aqueous solution of a precondensate of an aldehyde with another aldehyde, a ketone, an aldehyde-alcohol or a ketone-alcohol, together with an alkaline catalyst, drying the fabric, subjecting the fabric to the mechanical ornamenting treatment, heating it to insolubilize the resin in the parts free from said salt, washing to remove soluble residues and to remove the mechanically produced effect from the salt-impregnated parts and finally drying.  Specified salts are those of weakly basic metals such as aluminium, cadmium, chromium, lead, manganese, tin, zinc and zirconium, with weak organic acids, e.g., acetic and formic acids, and those formed from organic acids of moderate or low solubility with volatile bases, e.g. the ammonium salts of salicylic, sebacic, 2 - hydroxy - 3 - naphthoic, benzoic and p-chlorobenzoic acids.  Specified condensation products are those of formaldehyde with acetone, methyl ethyl ketone, cyclohexanone, acetaldehyde, crotonaldehyde, aldol and diacetone alcohol.  Coloured effects are obtained by the addition of dyestuffs or dyestuff components, e.g. vat or acid dyes, to the salt or precondensate solution, and when the salt solution contains a salt of aluminium or chromium the residual hydroxide enables the printed parts to be dyed with a mordant dyestuff.  The printing solutions may also contain matting or optical whitening agents and water-repellant substances. To prevent differential shrinkage the fabric is preferably preshrunk and/or held to width during at least the final drying.  Numerous examples are given wherein the treatment is applied to cotton fabrics.  Specification 538,452 is referred to.

Title: Improvements in or relating to the treatment of tar and the like liquid hydrocarbons
IPC: C10C1/20
Filed: 1922-11-24
Abstract: A liquid hydrocarbon such as tar is heated to a temperature of 190 DEG  F. in a jacketed container to which 5 to 8 per cent of sulphuric acid and 2 to 3 per cent of nitric acid are added.  The mixture is stirred and when the action of the acids is completed paraffin oil is added to reduce the viscosity.  The mixture is allowed to stand, after which it is cooled causing a heavy constituent to sink to the bottom while the lighter oils may be drawn off for fractionation or other treatment.  The heavy binding material is then treated with water or alkali to wash out the acid, and run into moulds to harden. The residual material is suitable for use in making road blocks or artificial paving stones and for making electrical goods such as telephone receivers and fuse boxes.  The light oils may be used as paint for ships bottoms or for fuel oils, and benzenes, toluenes or xylenes may be recovered from them.  Specification 8069/13 is referred to.
