Title: Improvements in and relating to the production of oxygen-containing organic compounds from alkenes
Inventor: GODDARD REGINALD EDWIN
IPC: C07C29/141
Filed: 1955-08-22
Abstract: C8 oxygen-containing compounds are prepared by the carbonylation with CO and H2 at elevated temperature and pressure of a mixed heptene cut produced by the polymerization of lower alkenes, from which cut heptenes containing a terminal tertiary carbon atom have been substantially removed and whose content of 2,3-dimethyl-pentene-2 does not exceed 17% by weight. The aldehydes produced may be hydrogenated to alcohols, which may be esterified, e.g. with phthalic acid.  The content of heptenes containing a terminal tertiary carbon atom in the feed preferably does not exceed 3% by weight.  The mixed heptene cut may be obtained by fractional crystallization or fractional absorption and desorption with, e.g. diatomaceous earth and dinonyl phthalate, but the preferred method is precision batch distillation through an efficient tower, e.g. with 25 or more theoretical plates, at a high reflux ratio, to give a cut of boiling range 81.5-95 DEG  C.  The fractionation may be controlled chromatographically.  The preparation of the heptenes by polymerization of lower alkenes, and the carbonylation reaction, may be carried out by known methods.  Specifications 651,250, 663,240, 679,788 and 721,540 are referred to.

Filed: 1947-09-04
Abstract: 640,470. Printing-surfaces. COATES BROS. & CO., Ltd., and COATES, L. Sept. 4, 1947, No. 24434. [Class 100 (ii)] A bi-metallic planographic printing-plate is formed with a non-printing water-receptive surface of a metal such as chromium having its surface in slight relief relatively to the printing- surface of smooth copper. The plate is formed by coating a copper, or a copper-coated zinc, iron or aluminium plate with chromium by electrolytic or other means. A design is then transferred to the chromium by printing or photography. In the first case the plate is treated with a 2 per cent solution of nitric acid to make the chromium surface receptive to transfer ink, and the plate with a positive transfer image is flooded with an etch-resisting lacquer, and when dry the transfer ink is washed out by turpentine or white spirit leaving the etch resist on the uninked parts. The plate is etched with a solution of equal parts glycerine and hydrochloric acid. The resist is dissolved out in alcoholic caustic soda, and degreased with an abrasive powder moistened in 10 per cent caustic soda, and finally passivated by a 2 per cent solution of sulphuric acid, or a solution of phosphoric, or lactic acid. The etch-resisting lacquer may be composed of shellac 10 parts; methylated spirit 40 parts; ammonia 9 parts; water 39.7 parts; ammonium dichromate 1.0 parts; urea 0.3 parts. An alternative composition contains phenol formaldehyde resin, cellulose nitrate, alcohol, amyl acetate, ethyl lactate, butyl alcohol, methyl violet. To prepare the design photographically the chromium is coated with a solution of glue and ammonium bichromate and exposed through a line or screen photo-positive. The developed negative is dried and dyed with methyl violet, and the etching is carried out until the copper image is seen. After the negative is dried and hardened it is etched and finished as in the prior process.

Title: Continuous treatment of wool fabrics
IPC: D06M11/30
Filed: 1961-07-11
Abstract: Fabrics made from wool or other keratinous fibres e.g. hair or fur fabrics, are shrink proofed and sensitized by a continuous process comprising passing them through a bath containing an aqueous solution of an acid, e.g. sulphuric acid, to deposit on or in the fabrics, either in combination or physcially, 2.5-15% of acid based on the weight of the fabrics, passing them through an aqueous solution of an alkali metal bromate and alkali metal bromide or chloride, neutralizing excess acid and passing the fabrics through an aqueous solution of an alkali metal sulphite or bisulphite in sufficient amount to neutralize the free bromine plus an amount sufficient to reduce the disulphide linkages in the fibres, at a temperature not over 175 DEG F. to sensitize the fabric.  A sensitized fabric is one which upon being subjected to steaming and/or heating in a fixed position will tend to remain in that fixed position.  A wetting agent inert to halogen may be used to facilitate the treatment with acid and bromate solutions, e.g. condensation products of ethylene oxide and octyl- or nonyl phenols.  The acid treatment may be carried out at 100 DEG -120 DEG F. and the treatment with the bromate solution at a temperature of 120 DEG -140 DEG F. and the acid may be neutralized with an aqueous solution of sodium bicarbonate.  Sensitized fabrics may subsequently be dried at a temperature below 175 DEG -180 DEG F. to retain their sensitiveness, made into garments, formed into creases or pleats and then heated e.g. by steaming, to a temperature above 175 DEG -180 DEG F. to set the fabric or the fabric may be dried at a temperature below 180 DEG F. in a rapid current of air, subjected to a shearing, cropping, napping, lustering, polishing and/or other dry finishing process at a temperature not above 175 DEG -180 DEG F. and wound on to a decatising device and decatised or heated on a polishing roll or iron to set the fabric.  Alternatively the sensitized fabric may be held in a flat, smooth, creaseless state and dried at a temperature above 175 DEG -180 DEG F. to stabilize it.
