Title: Improvements in or relating to the stabilisation of aromatic amines
Filed: 1946-11-19
Abstract: A motor fuel, particularly a hydrocarbon motor fuel, contains an aromatic amine, e.g. xylidine, stabilised against discoloration by a small proportion of an aromatic biguanide.ALSO:Aromatic amines and particularly those having 0-6 alkyl carbon atoms, more especially alkarylamines having 1-3 alkyl carbon atoms, are stabilized against discolouration by the addition of an aromatic biguanide.  Aromatic amines which may be stabilized according to the invention include xylidine, the toluidines, the ethyl anilines, cumidine, N-methyl and N-dimethyl aniline and N-monoethyl aniline.  Suitable biguanides include xylyl, tolyl, phenyl, mesityl, ethyl phenyl, naphthyl and anthracyl biguanide, which are obtainable by reaction of the corresponding aromatic amines with a dicyandiamide.  In general from 0.01 per cent to 1.0 per cent of biguanide is sufficient for stabilization.  The stabilized amines may be used with a diluent, e.g. in a motor fuel.  In examples, xylidine is stabilized by the addition of xylyl biguanide and by the addition of ortho-tolyl biguanide.

Abstract: 1,092,251. Disc brakes. DUNLOP RUBBER CO. Ltd. Aug. 24, 1964 [Aug. 31, 1963], No. 34451/64. Heading FE. In a disc brake a non-rotatable caliper-type housing 2 having a pair of limbs 3, 4 straddling a portion of a periphery of a rotatable brake disc 1 and mounted on a pin 8 supported by a non- rotatable member 5 of the brake so that the housing can move in a direction parallel to the axis of the disc, one of the limbs 4 of the housing has a friction element 13 fixed thereto and the other limb 3 is associated with a friction element 14 which is movable axially into engagement with the disc, the friction element 14 being mounted on the pin 8 by means of a bush 17 provided on a backing plate 16 so that it can move in a direction parallel to the braking surfaces of the disc, the backing plate 16 having a corrugated surface on the side remote from the disc and slidably engageable with a complementary corrugated surface provided on a member 20 fixed to the housing to form a wedge device. When a tiltable thrust member (not shown) is actuated by an hydraulic piston-andcylinder device 15, movement of the axially movable friction element 14 in a forward direction parallel to the normal direction of forward rotation of the disc causes relative movement of the corrugated surfaces which generates an axial thrust tending to increase the pressure between the friction elements and the disc. The member 20 has moulded thereto a block 23 of heat-resistant plastic material and the member 20 is fixed to the housing by pegs 21 which fit into sockets in the link 3 of the caliper housing, the plugs 21 engaging recesses 22 in the member 20. The caliper housing 2 is prevented from rotation in a circumferential direction by the engagement of feet 9 and 10 formed on the housing with shoulders 11 and 12 respectively formed on the non-rotatable member 5. The invention may also be applied to a disc brake of the opposed cylinder type where both the housing and the disc are axially fixed and both friction elements are movable relative to the housing, it is necessary to provide two wedge devices, one for the friction element on each side of the disc, in order to balance the reaction forces set up on the housing by each wedge device.

Abstract: 1,107,675. Grinding. TREFIMETAUX. 3 Aug., 1966 [16 Feb., 1966], No. 34714/66. Heading B3D. A method of grinding dies of reducing rolling machines, each die having at least one groove or pass on its periphery, comprises simultaneously grinding two dies which are intended to operate together and are mounted on their shafts in their relative working positions. Each die consists of a cylinder 2, Fig. 1, formed with a groove 3 whose section decreases from point a to point b. The groove of each die has a part-circular portion 4, Fig. 3, and relieved portions 5 of slightly greater radius. As described, two shafts 21, 22, Fig. 5, carrying respectively dies 23, 24, 25 and dies 26, 27, 28 are supported by journals 19, 20 in carriages 13, 14 and 15, 16. The carriages are slidable on ways 11, 12 and are urged towards each other by springs 47 so that rollers 45 carried by the carriages engage cams 43 mounted on a rod 44. The end of the rod has a follower 42 engaging a cam 41 driven by a motor 34 which also rotates the shafts 21, 22 through gearing 35, 36 and shafts 37. The gearing is also connected by a splined coupling 51, 52 to a cam 53 engaged by a follower 54 on a lever 55 connected at its end to a grinding unit 29 to vary the eccentricity of a grinding wheel carried at its lower end, the wheel, which rotates about a vertical axis, moving with a planetary movement. The unit can be adjusted along a beam 10 and can be locked in position by pneumatic jacks 31. In operation, the shafts 21, 22 are mounted in the carriages and have their grooves previously rough formed, as on a lathe. The spindle of the grinding wheel is disposed in the grooves of a pair of dies and the motor 34 started so that the dies are rotated and moved transversely under the control of the cams 41, 43 at the same time as the eccentricity of the planetary movement of the grinding wheel is varied by the cam 53 to form the grooves of increasing depth. After each rotation or pass of the dies, the grinding wheel is lowered by a hand wheel 30 so that the wear occurring at the lower end of the tool is compensated and finally the cylindrical part of the grinding wheel engages the grooves. The relieved portions of the dies are then ground by replacing the cams 41, 43.

Title: Improvements in separating into its constituents the reaction mixture derived from the cyclo-octatetraene synthesis
IPC: B01D1/00
Filed: 1957-11-12
Abstract: <PICT:0815961/III/1> The components of a reaction mixture from the cyclo-octatetraene synthesis which contains solid and liquid substances are separated by steam distillation by leading steam into a column of water at a short distance below the surface so that a steam-water zone is formed above the water and introducing the mixture into this zone so that liquid constituents are vaporized while the solids fall downwardly through the non-turbulent water below the point of entry of steam and can be sluiced out.  Steam, for example at 1-10 atmospheres, is introduced by pipe 5 and annular pipe 9 provided with holes round the top and positioned just below the surface of water in a vessel 4 having a conical bottom contained in a vessel 1, the water level being fixed by overflow pipe 2. The reaction mixture is introduced from above by pipe 10.  Solids fall downwardly through the non-turbulent water into vessel 1 and thence into sluice 3.  Due to the freedom from turbulence the solids are not deposited on the wall and no incrustations are formed.  Vapours pass by pipe 6 to condenser 7 and are separated in separator 8 into an upper organic layer containing cyclo-octatetraene drawn off into storage tank 16 and a lower aqueous layer which, since it may contain organic constituents is preferably returned to the steam distillation.  Reduced pressure, e.g. 300-760 tons, may be used but atmospheric pressure is preferred.
