Abstract: 417,243. Flexible abrasive articles. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Minnesota Mining & Manufacturing Co. ; 791, Forest Street, St. Paul, Minnesota, U.S.A.) Dec. 22, 1932, No. 26011/34. Divided out of 417,177. Drawings to Specification. [Class 60.] In a flexible abrasive article comprising a layer of abrasive particles on one side of a flexible base or sheet, such as sandpaper, the base or sheet is saturated, impregnated, or coated on at least one side (with or without saturation or impregnation) with a composition including a protein and a sulphonated oil, with or without a flexibility augmenting agent. The same composition may be used as an adhesive for the abrasive particles. The protein may consist of glue, casein, or albumen, and the sulphonated oil of B.T. oil (chinawood oil treated with sulphur to render it non-drying), sulphonated cottonseed or castor oil, and the like. The flexibility augmenting agents may be hygroscopic materials such as calcium chloride, or organic hygroscopic materials such as glycerine, ethylene glycol, or diethylene glycol. Rubber or pigments, or both, may be added to the composition. To render the protein resistant to liquids employed with the abrasive article when in use, it is preferably insolubilized, the methods described for this purpose being the same as those described in Specification 417,177. A number of alternative arrangements on the flexible base of coatings of the protein and sulphonated oil composition, with or without coatings of varnishes formed of resins or cellulose derivatives, are described, these being the same as those described in Specification 417,177.

Patent GB-389156-A (GB)
Title: Improvements in dyeing wool by means of vat-dyestuffs
IPC: D06P1/28
Filed: 1931-09-22
Abstract: In oxidizing wool dyeings of water-soluble ester-like derivatives of leuco vat dyes by means of potassium bichromate or a similar oxidizing agent, there is added to the developing bath thiodiglycol, thiourea, or an aromatic aminosulphonic acid such as dimethylaniline-p-sulphonic acid.  These water-soluble compounds are more resistant to oxidation than the ester salts but are more easily oxidized than the vat dyes themselves, and thus prevent over-oxidation.  In an example wool dyed with the ester salt of leuco-5.7 : 5<1>.7<1>-tetrabromindigo is developed in a bath of acidified bichromate containing thiodiglycol. Specification 344,964 is referred to.  The Specification as open to inspection under Sect. 91 refers to the addition to the developing bath of a substance the oxidation potential of which is greater than that of the ester salt but smaller than that of the corresponding dyestuff.  This subject-matter does not appear in the Specification as accepted.
