Abstract: 1,127,135. Diene graft polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 1 Dec., 1965 [2 Dec., 1964], No. 50911/65. Heading C3G. 1,3-Dienes are polymerized in aqueous emulsion using a polymerization catalyst and in the presence of a diene polymer which has a crystallinity of more than 30% and a molecular weight of 15,000 to 1,500,000. The reaction is carried out at - 10‹ to 100‹ C. at a pressure of 1 to 20 atmospheres absolute. The catalysts may be inorganic or organic peroxides, redox systems or metal chelate complexes such as those described in Specification 1,065,406 and may be supplied to the polymerization vessel as an emulsion in a portion of the aqueous reaction medium. The partly crystalline diene polymers are generally derived from linear or branched aliphatic 1,3-dienes having 4 to 6 carbon atoms and are exemplified by 1,4-trans polyisoprene, 1,4-trans-butadiene and a polyisoprene having a 1,2-vinyl fraction of less than 10%; they are preferably supplied to the graft reaction in solution in hydrocarbons or emulsified, and may be supplied either continuously or intermittently during the polymerization. Suitable 1,3-dienes having 4-10 carbon atoms are butadiene, isoprene, 2,3-dimethylbutadiene, 2-phenylbutadiene, and 2-chlorobutadiene. In Examples 1 and 3, the 1,3-dienes are partially polymerized before the partially crystalline diene polymer is added. Monoethylenically unsaturated compounds, such as (a) α,#- ethylenically unsaturated aliphatic monocarboxylic acids having 3 or 4 carbon atoms and their esters particularly with alkanols having 1-8 carbon atoms, (b) esters of fumaric acid and maleic acid particularly with alkanols having 1-4 carbon atoms, (c) acrylic and/or methacrylic compounds such as their amides, nitriles and N-methylol derivatives thereof, (d) vinylaromatic compounds having one benzene nucleus, (e) vinyl ethers particularly of alkanols having 1-4 carbon atoms, and (f) vinyl ketones having 4 or 5 carbon atoms, may be copolymerized with the 1,3-dienes provided that these 1,3-dienes comprise at least 50% by weight of the total monomers.

Filed: 1974-11-29
Abstract: 1485029 Hydrodynamic transmission A BEZIMENSKY 29 Nov 1974 51893/74 Heading F2W In a fluid coupling or torque converter for a motor vehicle wherein the blades 2, 14 of pump and turbine elements 1, 11 have leading edges inclined to corresponding radial planes, the blades are shaped to reduce the difference in path length of streams of fluid adjacent a core ring 5, 12 and adjacent the outer shell 4, 13 and thus reduced internal friction losses within the coupling or converter. The inclination of the leading edges of the blades relative to the radial plane is between 40 and 75 degrees and the leading edges of the pump are inclined in the direction of rotation whilst the leading edges of the turbine are inclined in the opposite direction to the direction of rotation. In the case of a torque converter the leading edges 20a of blades 20 of a reaction wheel are inclined in the direction of free wheeling at an angle to the radial plane which is between 40 and 60 degrees. In Figs. 6-8 (not shown) a second turbine (17) is interposed between the pump and turbine elements (1, 18). In Figs. 11 and 12 (not shown) an intermediate shell (27) is provided between the inner core (25) and outer shell (26) of the turbine wheel and the shell (27) is moved axially to throttle the flow passages in the turbine. The shell (27) is automatically positioned by the pressure within the coupling which acts in opposition to a spring (30). In Figs. 13 and 14 (not shown) a torque converter has an intermediate shell (35) which throttles the flow passages through the turbine. The shell (35) is moved in opposition to a spring (43) by the pressure within the working circuit. A linkage (38) is provided to prevent tilting of the shell (35). Figs. 16 and 17 (not shown) are similar to Figs. 13 and 14 but the spring is replaced by a fluid filled bellows (56). In Fig. 18 (not shown) a torque converter has a second turbine (59) positioned between pump and turbine elements (58), (60) and the second turbine has variable incidence blades (62) which are controlled by pressure wthin the converter acting against a fluid filled bellows (68) which acts between a fixed abutment plate (69) and a plate (70). Expansion of the bellows (68) causes inclined arms (73) to rotate about their pivot (72). The other ends of the arms (73) are connected by a pin (74) to a ring (75) which is thus rotated. Rotation of the ring (75) acts through pins (77) and an arm (79) to rotate the blades (62).

A method of moulding a plastics container or other article having a sculptured surface portion of a different colour or composition from a base structure, comprises injection moulding a shell 78 in a mould 24 by means of an injection unit 32, opening the mould, removing the shell, placing it in a mould 26, and injection moulding the sculptured portion thereon with an injection unit 34. A platen 4, runner 52 and mould plate 30 are stationary, the moulds 24, 26 being opened when a platen 8 is retracted hydraulically. An ejector bar 81 carrying pins 82 is retracted with the platen 8 until stubs 88 abut the machine frame 2, whereon side mould parts continue to retract but members 84, 86 encircling the respective mould cores are pushed therefrom and towards the plate 30.

The mould 26 is similar to mould 24 and also has a sculptured portion-forming part (80) in three arcuate members (86) surrounding the core and provided with sprue runners, Figs. 5, 9 (not shown). Injection in mould 26 is prevented if no shell is present therein by a safety switch including a rod (134) mounted in a bore (136) of a part (116), Fig. 9 (not shown), the rod (134) being spring-biased towards the plate 30. When a shell 78 is present, the plunger retracts, but when no shell is present it is urged outwardly by the spring to close switches in a housing (138) and connected to the injection apparatus 34.
