Title: Improvements relating to monoazo dyestuffs
IPC: C09B45/16
Filed: 1951-12-11
Abstract: 3 - Hydrazino - benzenesulphonamides (prepared from the amino-compounds by known methods) are condensed with oxalacetic esters to give 1 - (31 - sulphonamido - phenyl) - 5 - pyrazolone - 3 - carboxylic esters which are then reacted with ammonia or primary aliphatic amines to yield p  1-(31-sulphonamido-phenyl)-5-pyrazolone - 3 - carboxylic amides.  Examples show the production of (1) 3-hydrazino-benzene-sulphonamide, 1 - (31 - sulphonamidophenyl) - 5 - pyrazolone - 3 - carboxylic ethyl ester and the corresponding amide, methylamide and ethanolamide; (2) as in (1) where the sulphonamide group is N-substituted by methyl, ethyl or hydroxyethyl; (3) 4-chloro-3-hydrazino-benzenesulphonamide, 1 - (21 - chloro - 51 - sulphonamidophenyl) - 5 - pyrazolone - 3 - carboxylic ethyl ester and the corresponding amide, methylamide and ethylamide; (4) 2-chloro-5-hydrazino - benzenesulphonamide, 1 - (41 - chloro - 51 - sulphonamidophenyl) - 5 - pyrazolone - 3 - carboxylic ethyl ester and amide, and the corresponding compounds substituted in the sulphonamide group by methyl or ethyl.  The products are dyestuff intermediates.ALSO:The invention comprises monoazo dyestuffs of the formula <FORM:0697517/IV (c)/1> where R is an aliphatic or alicyclic hydrocarbon radical of 4-8 carbon atoms, R1 and R11 are hydrogen or alkyl or hydroxyalkyl of 1-6 carbon atoms and X is chlorine or hydrogen (not both chlorine).  These are made by coupling diazotized 6-nitro-4-alkyl- or cyclo-alkyl-2-aminophenols with 1-(31-sulphonamidophenyl) - 5 - pyrazolone - 3 - carboxylic esters or amides and if necessary converting the ester group to amide by reaction with ammonia or amines.  The products dye wool and other keratin fibres and synthetic fibres bluish-red by the metachrome or afterchrome method.  In wool/cellulose blends the latter is largely reserved.  In the examples the following dyestuffs are prepared: (1) 6-nitro-4-t-amyl-2-aminophenol --> 1 - phenylpyrazolone - 3 - carboxylic amide - 31 - sulphonamide; (2) 6 - nitro 4 - t - amyl - 2 - aminophenol --> 1 - phenylpyrazolone - 3 - carboxylic ethyl ester - 31 - sulphonamide; treatment with ammonia converts the carboxylic ester group into carboxylic amide; (3) as in (2) treating the ester with methylamine; (4) 6 - nitro - 4 - cyclo - hexyl - 2 - aminophenol --> 1 - phenylpyrazolone - 3 - carboxylic amide - 51 - sulphonamide; (6) 6 - nitro - 4 - t - amyl - 2 - amino - phenol --> 1 - (41 - chlorophenyl) - 5 - pyrazolone - 3 - carboxylic amide - 51 - sulphonamide; (7) 6 - nitro - 4 - t - amyl - 2 - aminophenol --> 1 - (41 - chlorophenyl) - 5 - pyrazolone - 3 - carboxylic ethyl ester-51-sulphonamide, and after-treatment with ammonia, methylamine, ethylamine or ethanolamine.

Abstract: 1442489 Clutch-brake combinations; friction clutches; full-face disc brakes GULF & WESTERN MFG CO 1 July 1974 [29 Aug 1973] 29109/74 Headings F2L F2C and F2E A clutch and brake unit for a press comprises an input shaft 56 on which a flywheel 28 is mounted, and an output shaft 46 parallel to and laterally spaced from shaft 56, the output shaft 46 being driven from shaft 56 via gears 66, 68 and a clutch 72 and having a brake 74 for interconnecting a fixed housing 34 and the shaft 46. Due to the sizes of gear 66 and gear 68, which is a ring gear the input shaft rotates faster than the output shaft 46 driven by it. The clutch 72 and brake 74 are actuated by presser members 78, 80 respectively, these being axially moved by an annular piston 76 which actuates the clutch 72 when pressure fluid, such as air, is supplied to an annular chamber 77 from a passage 128 and the brake is actuated by springs 130, 142 (and the clutch disengaged) on release of this pressure. The opposite end of piston 76 may receive fluid pressure to aid the springs. The clutch and brake pressure members 80, 78 are interconnected by a roller bearing since the clutch presser member rotates with the output shaft and the brake presser member and piston 76 are fixed against rotation to the housing by dowel pins 132. The construction of the piston 76 shown and its cylinder is such that no change of the volume in the housing occurs when it moves, and so the housing may be filled with cooling and lubricating fluid such as oil without undesirable pressures occurring due to such a volume change. The oil for cooling and lubrication may be circulated through the housing and externally cooled, ports 154 and 156 in the housing being employed for this.

Abstract: 323,796. Romer, L. R., and Trist & Co., Ltd., R. Oct. 10, 1928. Fluid-actuated valves; dash-pots, applications of.-In a feedwater regulator, for steam boiler and the like, of the type in which the valve controlling the feedwater supply is fluid-pressure operated, the pressure being controlled by a device responsive to changes of water level in the boiler, the feedwater controlling valve d is prevented from closing completely by the action of a dash-pot t of the closed-circuit type. The valve d is urged towards the closed position by a piston k attached to the top end of the valve stem, the piston working in a chamber to which pressure is admitted at j by a controlling device operated by the changes in boiler water level; this device may be of the form described in Specification 323,797. The valve stem f passes through the slotted horizontal lever n, one end of which is pivoted at o whilst the other end is coupled by a rod r to the piston of the dash-pot. The lever n is spring-loaded to oppose the action of the fluid pressure on the piston k, the purpose of the retardation of the water-supply valve as it nears its seat, provided by the dash-pot and spring, being to maintain the valve in a partly open position so that the boiler may receive a continual stream of feedwater, the dash-pot being designed to limit the closing speed of the valve to a value which will ensure the re-adjustment of the boiler water level before the valve can reach its seat.
