Title: Methods of and machines for dressing grinding wheels
IPC: B24B53/06
Filed: 1971-09-09
Abstract: 1367488 Trueing grinding wheels SKF (UK) Ltd 10 Oct 1972 [9 Sept 1971] 42161/71 Heading B3D A method of dressing the periphery of a grinding wheel 10 to provide it with a profile comprising two convex circular arcs 37 with a valley therebetween comprises moving a dressing tool 35 across the periphery in a direction parallel to the axis of rotation of the wheel and, at the same time, towards and away from the axis by means of two arms 21, 22 which pivot in succession about fixed abutments 29, 30 as the tool is moved across the periphery. The dressing mechanism has a base 15 which is slidably mounted on the bed of the grinding machine for movement towards and away from the grinding wheel which is arranged for grinding the tracks on the inner ring of a bearing heaving a double row of part-spherical rollers. A primary carriage 16 is movable by an actuator parallel to the axis of the grinding wheel on the base 15 and supports a secondary carriage 18 movable perpendicularly to the axis, the carriages sliding on re-circulating ball slides. A dressing tool 35, which may be a diamond-pointed tool or acutting wheel rotated by a flexible drive shaft 36 is mounted on a holder 19 on the secondary carriage which also mounts a pivot 20 for the lever arms 21, 22 swingable about an axis 26. The secondary carriage is spring-biased towards the grinding wheel and to a position determined by engagement of an abutment with a stop adjustable by a micrometer screw 24. The arms are adjustable in length by screws 33, 34 and are fixed to one another at a set angle. The ends of the arms have part-spherical ends 27, 28 for engagement with respective abutments 29, 30 on the base 15, the abutments being adjustable in a direction parallel to the axis of the grinding wheel by screws 31, 32. During dressing, the arm 22 is initially out of engagement with the abutment 30 and the secondary carriage. During the movement the processing carriage 16 moves in a circular arc under the control of arm 21 and abutment 29 so that the tool 35 forms the first are from point A. At the end of the first arc, the abutment 25 is engaged by the stop 23 so that the dressing tool moves parallel to the axis of the wheel to dress a cylindrical portion until the arm 22 engages the abutment 30 and the secondary carriage, and hence the tool, is moved to dress the second circular arc on the wheel up to the point B. In another embodiment, the arms 21, 22 are telescopic between their ends 27, 28 and the pivot 26 and their length is governed by internal stops.

[Also in Division F2] Two or three speed-ratios in both directions are provided in a locomotive transmission driven by four diesel or gas-turbine engines, and comprising two contra-rotating shafts 21, 22, connected together by meshing gear-wheels 25, 26 meshing further gear-wheels 24, 27 on shafts 20, 23, which, like the shafts 21, 22 carry flanges 12, 13, 14, 15 for connection to the driving engines. For forward or reverse the wheels 25, 26 are alternatively clutched by coupled dog-clutches 31, 41, to stepped gear-wheels 35, 36 and 45, 46 respectively concentric with the shafts 21, 22. Both smaller steps 35, 45 mesh a wheel 61, Fig. 2, whilst both larger steps 36, 46 mesh a wheel 62, the wheels 61, 62 being selectively clutchable to a final output shaft 60 to provide two speed ratios by synchromesh clutches 58, 59 as described in Specification 640, 227. In Fig. 3 (not shown) the two speed ratios are obtained at the input side of the gear and forwardreverse at the output side instead of vice versa as in Figs. 1 and 2. Single meshed wheels (90, 93) free on the contra-rotating shafts (75, 76) mesh respective wheels (95, 96) selectively clutchable to an output shaft for forward-reverse as described in Specification 959, 582. The contrarotating shafts (75, 76) are flange-coupled at (71, 74) to two engines, and at their opposite ends have small pinions (84, 85) meshing larger wheels (80, 81) free on the shafts (75, 76) and equal pinions (77, 78) flange-coupled to the other two engines. By alternatively clutching at (82, 83, 91, 94) the meshed wheels (90, 93) to the contrarotating shafts (75, 76) or to the larger wheels (80, 81) drive to the meshed wheels (90, 93) is either direct or at the reduction ratio of the wheels (77, 80). Fig. 4 (not shown) uses the same output arrangement as Fig. 3 (not shown) but the speed-reduction ratio is now obtained by wheels (122, 126) meshing the output meshed wheels (115, 116) and clutchable at (125, 127) to shafts (105, 108) parallel to the adjacent contra-rotating shafts (106, 107). Fig. 5 (not shown) provides a third ratio by adding to the Fig. 4 (not shown) embodiment meshing wheel pairs (130, 132) on the shafts (108, 107) introduced by an additional dog clutch (131). In the embodiments of Figs. 3 and 4 (not shown) power-sustained gear shifts are possible when the engines drive through torque-converters, so that alternate pairs of engines can be idled to permit shift of the dog clutches relating to that pair whilst the other pair remains under load.
Patent GB-1063439-A (GB)
Title: Process for preparing graft polymers
IPC: C08F279/02
Filed: 1965-10-19
Abstract: Thermoplastic graft polymers are made by preparing a latex of a polydiene or a copolymer of a diene, submitting the latex particles to agglomeration, adding monomeric material to the agglomerated latex and heating the resulting mass in the presence of a free-radical catalyst to polymerize the monomeric material. Specified dienes are butadiene, isoprene, 2,3-dimethylbutadiene, pentadiene, hexadiene and octadiene, which may be polymerized alone or with monomers such as styrene, alpha-methylstyrene, vinyl naphthalene, monochlorostyrenes, acrylic acid, methyl acrylate and methacrylate, acrylonitrile, methacrylonitrile and methacrylamide, these monomers also being suitable as grafting monomers.  The agglomeration of the diene polymer latex may be effected by freezing and thawing it, by adding an agglomerating agent thereto, e.g. a polyvinyl ether, or by forcing the latex through an orifice.  The examples describe making graft polymers by polymerizing mixtures of styrene and acrylonitrile in agglomerated latices of polybutadiene, polyisoprene and butadiene-acrylonitrile, butadiene-styrene and isoprene-acrylonitrile copolymers, and by polymerizing a mixture of styrene and methyl methacrylate in an agglomerated latex of a butadiene-acrylonitrile copolymer.

The temperature of a strip S before passing to the finishing stands 14-19 of a rolling mill is maintained constant by controlling the radiation losses of the strip using shields 22-24. The temperature of the strip is measured by pyrometers 33-35, and if the temperature measured at one location is, for example, below a desired figure set on a corresponding rheostat 37, 38, or 39 then the appropriate shield 22, 23, or 24 is moved to a position above the strip in order to inhibit radiation losses. Similarly, temperatures which are too high at any measuring point will cause the appropriate shield or shields to be raised clear of the strip. A shield can conveniently be heated by the leading end of a strip so that it can subsequently radiate heat to a later section of the strip. Each shield is corrugated at 42 (Fig. 2, not shown) and mounted on two pairs of parallel arms 26 for movement by a pneumatic piston and cylinder 29. The strip S is supported on driven rollers 32.
