Title: Dyeing of furs, pelts and hair and new dyestuffs therefor
IPC: D06P3/30
Filed: 1936-05-27
Abstract: Monoazo dyes; acid wool and mordant dyes, dyeing with.--Furs, pelts and hair are dyed in level shades, fast to light and rubbing, with monoazo dyes obtained by coupling diazotized picramic acid with an aminonaphthol free from sulphonic or carboxylic groups or an N-substituted derivative thereof.  The manufacture of the dyestuffs having as coupling component an N - hydroxyalkylaminonaphthol is also claimed.  The materials are, preferably, subjected to a preliminary degreasing and purification treatment with alkaline agents, such as soda ash, ammonia, lime or caustic soda and, after removing residual alkali, to a chrome tanning treatment, e.g. with chrome alum, an alkali bichromate or basic chromium sulphate.  Any resulting acidity is then neutralized with sodium bicarbonate to a pH of 6 to 7 before the dyeing.  The materials may be further pre-treated with hypochlorites or phosphates to increase the dyeing capacity of the hairy portions and promote even dyeing.  Examples are given of the manufacture of the dyestuffs having as coupling component (coupled alkaline) 1-(b -hydroxyethyl)amino-5-naphthol (cf. Specification 436,805), 1-dimethylamino-5-naphthol and 1-acetylamino-5-naphthol and (coupled acid) 1-b -hydroxyethyl)amino-5-naphthol.  In examples of the dyeing process: (1) chrometanned long haired white rabbit fur is entered into an aqueous bath at 40 DEG  C. containing the dyestuff, picramic acid --> (alkaline) 1 : 5-aminonaphthol, and the temperature is raised during 20 minutes to 75 DEG  C. and so maintained for 30 minutes, acetic acid is added, dyeing is continued for 30 minutes, formic acid is added and the dyeing continued for 40 minutes, whereupon the fur is dried and drummed in sawdust to obtain a nigger brown dyeing; (2) chrome-tanned shorn white rabbit fur is entered into an aqueous bath at 40 DEG  C. containing the dyestuff, picramic acid ---> (alkaline) 1-(b -hydroxyethyl)amino-5-naphthol, and the temperature is raised during 20 minutes to 55--60 DEG  C. and so maintained with addition as in (1) of acetic and formic acids, whereupon the fur is dried and drummed as in (1) to obtain a reddish nigger brown dyeing, fast to rubbing.  A table is also given showing the shades obtainable with the dyestuffs from the following additional coupling components, viz.: (coupled alkaline) 1 : 7-, 2 : 5- and 2 : 7-aminonaphthols, 1 - acetylamino - 7 - naphthol, 1-(b hydroxyethyl)amino-7-naphthol and 2-phenylamino-7-naphthol and (coupled acid) 1 : 5-, 1 : 6-, 1 : 7- and 2 : 7-aminonaphthols, and 1-(b -hydroxyethyl)amino - 6- and -7 - naphthols.  Specification 10716/15, [Class 2 (iii)], also is referred to.  1-(b -Hydroxyethyl)amino-6- and -7-naphthols are obtained by condensing 1 : 6- and 1 : 7-aminonaphthols respectively with ethylene chlorhydrin in presence of an acid binding agent, e.g. chalk or sodium acetate.

Title: Manually adjustable valve for modulating hydraulic pressure
IPC: F16K31/44
Filed: 1973-03-30
Abstract: 1358820 Valves; clutch control DEERE & CO 30 March 1973 [30 March 1972] 15486/73 Headings F2V and F2L A manually adjustable valve, e.g. for controlling the hydraulic actuator of a normallydisengaged power take-off clutch of a vehicle, comprises a body 10 having parallel bores 12, 14 respectively containing a spool valve 38 and a piston 58 both associated with a common actuating lever 68 manually adjustable by means (not shown). The spool valve is shown in its closed position wherein a pressure fluid inlet port 28 is isolated from an outlet port 30 leading to the actuator, wherein a pressure chamber 56 is closed save for a connection to port 30 via a passage 36, and wherein the port 30 and a pressure chamber 60 are communicated with a sump (not shown) via recesses 48, 52 and channels 20, 22. Anticlockwise rotation of lever 68 moves the valve 38 downwardly via a link 84 and modulating spring 90 to establish communication between the ports 28, 30 via recess 44 whereby pressure builds up in the actuator and in the chamber 56, the pressure increase in the latter eventually returning the valve 38 to its closed position against the action of spring 90. Similarly, further anti-clockwise rotation of lever 68 temporarily opens the valve causing a further pressure build up in the actuator and chamber 56. After the lever has been rotated sufficiently for the top end of a lost-motion slot 92 in link 84 to engage a pin 94 carried by the valve, further rotation causes positive opening of the valve, eventually causing pressurization of chamber 60 via chamber 56, slot 54 and passage 32 and thereby raising of piston 58 to lock the valve in its fully open position. Subsequent clockwise rotation of the lever causes the valve to return to its closed position where it is retained by the action of a light spring 80. A pressure failure would also cause the valve to return to its closed position.
