Title: Decoloring or bleaching animal fibres
IPC: D06L4/10
Filed: 1924-03-10
Abstract: Animal fibres such as wool are bleached by subjecting them to the action of sulphuric acid, at ordinary atmospheric pressure at a temperature between 30 DEG  and 70 DEG  C., of such concentration and for such a time that no damage is done to the animal fibre or to vegetable fibre if present.  In the case of wool alone it may be treated with sulphuric acid of a strength of 30 per cent volume at 70 DEG  C. for 30 seconds or if the temperature is reduced to 54 DEG  C. it may be treated for 90 seconds.  If further bleaching is required the wool may be washed to remove all but 5 per cent more or less of the acid and with other bleaching agents while wet. When the wool contains vegetable fibre the acid used is of a strength of about 5 per cent by volume, more or less, at 70 DEG  C. and the treatment lasts for ten minutes.  Other bleaching agents such as hydrosulphide of soda may be added to the bath or the wool may be immersed in such a bath after treatment with sulphuric acid.

A fluid-pressure, tractor-trailer braking system has interconnected tractor and trailer service lines 54, 28, 24 and emergency lines 64, 38, 34, supplied with pressure from a source 44 on the tractor, the tractor and trailer brakes 10, 12, 20 being applied by pressure increase in the service lines and the trailer brakes 20 being applied in an emergency by a decrease in pressure in the emergency lines, and a protection valve 60 comprising axially aligned control chamber 136, service outlet and inlet chambers 112, 76, emergency outlet and inlet chambers 114, 78 and exhaust chamber 98, the chambers 76, 78 communicating with tractor lines 54, 64 and chambers 112, 114 with trailer lines 28, 38 respectively, an emergency valve 74 in chamber 78 being biased by spring 86 to the closed position, the system being characterized by a piston 130 movable in chamber 136 and having an integral projection 126, 120 extending through the service chambers 112, 76 and terminating at 122 in emergency chamber 114 and having an integral service valve 72 in chamber 76, the piston 130 being urged by spring 84 to close valve 72, the piston projection 126, 120 being engageable with the emergency valve 74 to open the same when piston 130 moves in the opening direction. When pressure in tractor reservoir 44, charged by compressor 41, reaches a predetermined value a governor 142 connects chamber 136 to the reservoir, piston 130 being moved to open valve 72, then close the venting passage 116 from the trailer brake system, and then open valve 74, fluid then flowing through emergency lines 64, 38, 36 and trailer relay valve 22 to charge the emergency reservoir 30. Service application of brakes 10, 12, 20 is obtained by pressurizing lines 14, 16 and the service line 54, 28, 24 from the pedal-actuated valve 18. A hand-operated valve 52 may be used to pressurize the trailer service lines only. Should pressure in the main reservoir fall below a predetermined value, then governor 142 vents chamber 136 and springs 84, 86 close valves 72, 74, the emergency line 38, 34 being vented via passage 116, chamber 98 and port 118 to cause valve 22 to apply the trailer brakes from reservoir 30. For an emergency trailer brake application the driver vents chamber 136 through a threeway valve 144. If the trailer breaks away, then venting of lines 38, 34 causes application of the trailer brakes; the pressure in the tractor system decreases until governor 142 vents chamber 136 to cause closure of valves 72, 74, sufficient pressure being retained in reservoir 44 to effect an application of the tractor brakes. U.S.A. Specification 2,850,330 is referred to. Reference has been directed by the Comptroller to Specifcation 683,350.

Title: Improvements relating to the application of bodies for dyeing and other purposes
IPC: D06P3/14
Filed: 1925-03-07
Abstract: The process of Specification 186,057, according to which leuco derivatives of vat dyes are converted into soluble esters by treatment with acids such as chlorosulphonic acid, preferably in the presence of a tertiary base, is extended to the production of similar esters of any other compounds which can be so converted; particularly suitable are compounds which, after reduction, contain groups into which the acid residue may be introduced.  The ester salts are reconverted, by saponification or acid oxidation, to the parent substances, which may thus be obtained in a finely divided state upon substrata.  According to examples (1) wool is dyed a full black by immersing in a bath containing the sodium salt of the sulphamino derivative of p-aminodiphenylamine and oxidizing with bichromate; (2) fibre is treated with the sodium salt of the disulphuric ester of hydrochloranil (made by treating hydrochloranil with chlorsulphonic acid in the presence of dimethylaniline), oxidized with sodium bichromate to regenerate cloranil, and finally a brown shade developed by treatment with aniline hydrochloride.ALSO:The process of Specification 186,057, according to which leuco derivatives of vat dyes are converted into soluble esters by treatment with acids such as chlorosulphonic acid, preferably in the presence of a tertiary base, is extended to the production of similar esters of any other compounds which can be so converted; particularly suitable are compounds which, after reduction, contain groups into which the acid residue may be introduced.
