Title: Audible relief valve
Inventor: CRANAGE BIDWELL CHAPMAN
IPC: F16K17/04
Filed: 1969-04-02
Abstract: 1,212,147. Valves. STILE-CRAFT M.F.R.S. Inc. 2 April, 1969, No. 17286/69. Heading F2V. A pressure relief valve for attachment to a humidifier has a piston 24 formed with a conical spigot on its base for closing the inlet passage 35 in a resilient seal 34 and movable against the bias of its own weight under inlet pressure to permit pressure fluid to flow into chamber 21 and thereafter into chamber 22 when the end flange of the piston moves into chamber 22. Pressure fluid is released through slot 44 formed between a flange 28 on a cap 20 and the wall of the base 17 and passes through a slot 45 formed with a whistle lip 47 which communicates with resonant chamber 23. When the end flange of the piston moves into chamber 22 fluid can pass out of chamber 21 faster than it can flow into it so the piston moves down to close the inlet again. Pressure release and the whistling are thus intermittent.

Title: Process for the manufacture of azo dyestuffs
IPC: C09B43/10
Filed: 1927-07-01
Abstract: 297,884. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). July 1, 1927. Azo dyes are produced by reducing to an azoxy or azo group the nitro groups from two molecules of a dyestuff obtained by coupling diazotized 5- nitro-2-aminobenzoic acid with a component. The products give dyeings which are rendered fast to light and to washing by after-treatment with metallic, e.g. copper, salts, and those containing diazotizable amino groups may be diazotized and coupled with components in substance or on the fibre. The following examples are specified :- (1) Diazotized 5-nitro-2-aminobenzoic acid is coupled alkaline with 2-amino-8-naphthol-6-sulphonic acid, and the monoazo product is reduced in alkaline solution with glucose at about 50‹ C. The resulting diamino trisazo or disazoazoxy dyestuff is diazotized and coupled with 2 : 4-diaminoacetanilide. The product gives on cotton black dyeings which are rendered fast to light and washing by treatment with metallic salts. (2) Diazotized 5-nitro-2-aminobenzoic acid is coupled with 2-amino-5-naphthol-7-sulphonic acid, and the monoazo product is reduced as in (1) above. The resulting trisazo or disazoazoxy dyestuff gives on cotton violet dyeings. It may be diazotized on the fibre and coupled with #-naphthol to give a black-blue dyeing which is made fast to light and washing by treatment with copper sulphate. (3) Diazotized 5-nitro-2-aminobenzoic acid is coupled with 2-phenylamino-5-naphthol-7-sulphonic acid, and the monoazo product is reduced in alkaline solution with glucose at about 60‹ C. The resulting trisazo dyestuff gives on cotton violet dyeings which on treatment with copper salts become clear blue, fast to light and washing. (4) Diazotized 5-nitro-2-aminobenzoic acid is coupled in acetic acid solution with 2 - acetylamino-5- naphthol-7-sulphonic acid, and the monoazo product is reduced as in (3) above. The reduction product dyes cotton similarly to that in (2) above. (5) Diazotized 5-nitro-2-aminobenzoic acid is coupled in acetic acid solution with 1-#- naphthyl-3-methyl-5-pyrazolone-6<1>-sulphonic acid, and the monoazo product is reduced by heating with glucose in alkaline solution. The reduction product gives on cotton orange dyeings which become brick red on treatment with copper salts. Specifications 11866/08 and 5736/90 are referred to.
