Title: Improvements in and relating to stable dispersions of secondary aromatic amines
IPC: C09K23/00
Filed: 1946-02-01
Abstract: In the process of preparing aqueous dispersions of secondary aromatic amines containing at least one -NH- group attached to two aromatic rings, wherein the amine is dispersed in water by means of a dispersing agent, the invention resides in the step which comprises incorporating from 0.1 per cent to 10 per cent, based on the weight of amine of a primary straight-chain aliphatic alcohol containing 8-18 carbon atoms or mixtures thereof, before dispersion is complete. Derivatives of alcohols which decompose readily to give free alcohols may be used.  Examples of secondary amines dispersed are diphenylamine, dinaphthylamine, diphenyl-p-phenylene diamine, dinaphthyl-p-penylene diamine, p-benzyl diphenylamine, p-phenyl diphenylamine, o-methyl diphenylamine, p-p1-dichloro diphenylamine, p-methoxy diphenylamine, ditolylamine, and p-isopropoxy diphenylamine, while the aromatic rings may contain non-functional substituents such as phenyl, benzyl, methyl, methoxy, phenoxy, and chlorine. The preferred dispersing agent is the sodium salts of the reaction product of naphthalene, formaldehyde and sulphuric acid but others such as sodium salts of sulphonated alcohols, or mixtures thereof, purified sulpholignins, and the sodium salts of aliphatic sulphonates of petroleum hydrocarbons and the like may be used.  The alcohol is preferably added during the manufacture or flaking process, but may be added during preparation of the dispersions with subsequent milling.  In the preferred process the amine is melted and 1 per cent of alcohol added and the melt is flaked on a drum flaker. The flaked material is made into an aqueous dispersion with the preferred dispersing agent and this mixture is ground in a Colloid mill for 20 minutes.

Title: Hydraulically operated clutch mechanisms
IPC: F16D48/02
Filed: 1952-02-12
Abstract: 727,144. Controlling clutches. AUSTIN MOTOR CO., Ltd., and STUART, D. J. K. Feb. 11, 1953 [Feb. 12, 1952], No. 3662/52. Class 80 (2) [Also in Groups XXVI and XXIX]. A friction clutch for a vehicle or other power transmission is spring engaged and is disengaged by a fluid pressure servo motor, a speedresponsive valve allowing clutch engagement when the engine speed exceeds a predetermined value. As shown in Fig. 1, the space 9 behind a hydraulic clutch disengaging piston 11 is supplied with fluid under pressure from an engine driven pump 1 via lines 2, 4, 8 and a valve 17. This valve is axially movable against a spring 31 by a centrifugal device 27 responsive to engine speed. Tapered portions of the valve 17 co-operate with ports 15, 16 to control communication between the line 8 and, respectively, the supply line 4 and an exhaust line 14. An additional centrifugal device 28 responsive to the speed of the clutch output shaft assists the device 27 in moving the valve 17. A relief valve 3 is provided. At a predetermined speed, above the idling speed, of the engine the device 27 will move the valve 17 to gradually cut off the supply line 4 and open the line 8 to exhaust allowing the clutch to engage. As the output shaft begins to rotate, the device 28 will become effective to move the valve 17 more rapidly and increase the rate of clutch engagement. The device 28 will also prevent clutch disengagement until the engine speed is below that for engagement. In a modification, Fig. 2, the valve is controlled by fluid pressure means. The valve stem 31 is cylindrical and has tapered grooves 43, 44 instead of conical portions control. ling communication between lines 40, 41, 42 corresponding to lines 4, 8 and 14 respectively of Fig. t. A slot 64 allows very rapid clutch disengagement, e.g. during an emergency stop. The stem 31 is movable axially against a spring 58 by differential pressures applied to diaphragms 52, 60. The differential pressures are derived from restrictions 45 in the supply lines of pumps driven by the engine and gear box output shafts. Valve 46 lifts against a spring 48 to limit the pressure drop at high speed. The function is similar to that of the first embodiment and, in addition, when the second speed-responsive device 63 is functioning alone (e.g. with engine stopped and vehicle in motion) the valve will be closed to allow the clutch to engage. An alternative means of obtaining the differential pressures dependent upon input speed of the clutch and output speed of the gear box is shown in Fig. 3 for use with the valve arrangement of Fig 2. A venturi 67 is disposed in each pump supply line and is tapped at 66, 68 for connection to each side of a diaphragm 52 or 60. A relief valve 74 by-passes the venturi at high rates of flow.
