Patent GB-1082227-A (GB)
Title: Process for preparation of polyester
IPC: F25J1/00
Filed: 1965-06-21
Abstract: Polyesters are made by reacting (a) an organic dicarboxylic acid or anhydride with (b) a vicinal alkylene oxide containing three or four carbon atoms and having attached to a carbon atom of the oxirane ring a methyl or ethyl group substituted by two or more fluorine, chlorine or bromine atoms, in the presence of a catalyst which is a reaction product of aluminium isopropoxide and a carboxylic acid.  The catalyst may be added as such or formed in situ.  Up to 50% by weight of the alkylene oxide may be replaced by a second vicinal alkylene oxide which is saturated and which on either or both of the carbon atoms of the oxirane ring, is unsubstituted or is substituted by one or two alkyl and/or alkoxy groups having 1 or 2 carbon atoms and in which one of the alkyl or alkoxy groups may be substituted by one halogen atom. The dicarboxylic acid may be malonic, succinic, perfluorosuccinic, glutaric, perfluoroglutaric, adipic, perfluoroadipic, pimelic, suberic, azeloic, sebacic, tetrahydrophthalic, hexahydrophthalic, chlorendic, phthalic, isophthalic, terephthalic, maleic, fumaric, chloromaleic, itaconic, citraconic or mesaconic.  Monocarboxylic acids may also be included in the reaction mixture.  The polyesters derived from unsaturated dicarboxylic acids may be copolymerized with unsaturated monomers, e.g. styrene, butyl methacrylate, triallyl isocyanurate or diallyl phthalate.  A suitable polymerization catalyst is benzoyl peroxide, with or without dimethyl phosphite.

In the embodiment of Fig. 8 a third weft yarn is drawn from one of packages 152 mounted on the far side of support pillar 90 from the laying station 10 and passed via hollow shaft 82 and yarn guide arm 155. A yarn guide arm 154 is provided for yarn 30. Net forming. The two (or three) weft yarns 28, 30 pass through rotating hollow shaft 22 and hollow guide arms 20, 21. (In the embodiment of Figs. 9-11, not shown, the arms 20, 21 are solid and guides 162 having ceramic eyelets 163 through which the yarns pass are mounted at intervals along each arm). Selvedge yarns 73 pass through the truncated cone 40 and helix 38 of the rotating yarn guides 36. Rolls 48, 50 press warp arrays 52, 54 onto the weft reaches. Binder is applied from bath 62 and the net is then passed around heated drying rollers 68. Shafts 22 and 82 and their associated guide arms are rotated at the same speed by motor 24, the drive being transmitted to shaft 82 via sprocket 74, 78, 79 and drive shafts 75, 80. Shaft 75 has universal joints (Fig. 4, not shown) at each end. The universal joints allow the axis of creel 18 to be at an angle to the axis of shaft 22 (Figs. 2, 3, not shown). Beams (56, 58) carrying warp arrays 52, 54 may thus be positioned closer to the winding station 10 thereby decreasing the length of the apparatus. Hollow shaft 82 is journalled in bearing housing 124, Fig. 6. Mounted on housing 124 is bearing housing 130 to which package supporting arms 136 are rigidly connected. Packages 108 are connected to one another through the use of a transfer tail, as are packages 32. Arm 127 connected to housing 124 carries a reflector 138. Should a bearing seize and housing 124 begin to rotate the reflector moves into the path of photoelectric eye 139 thereby opening switch (141, Fig. 7, not shown) and stopping motor 24.

Abstract: 859,014. Extruding; forging. LOEWY ENGINEERING CO. Ltd. Aug. 29, 1957, No. 27204/57. Class 83 (4). A locking-device for securing a press-tool 15 in its socket-shaped holder 11 comprises a number of plungers 22 movable in the holder by pressure means towards and away from the tool in a substantially radial direction and adapted to engage the tool and secure it in the holder. The device is described for use in an extrusion press wherein the main press ram 10 has bolted thereto a cylindrical holder 11 for receiving the pressing stem 15 which has an enlarged head 14 with splines 14A, a groove 19 and an end flange 18. Within the holder a resiliently mounted bearing 31, biased to the right by Belville washers 32, has splines complementary to those on the stem head which is first passed through the bearing splines into the holder and then rotated. The plungers 22 are advanced by pressure fluid supplied by a pump 68 from a reservoir 69 through valve 70 and duct 28 to the front of a fixed piston 23 disposed within a bore in each plunger. An indentation 30 in each plunger thus engages over the flange 18 of the pressing stem, Fig. 2 (not shown), and presses the latter firmly against a thrust-block 13. The plungers are retracted by pressure fluid admitted through valve 71 and duct 27 to the top side of piston 23 and thereafter the fluid is admitted through valve 74 to at least one chamber 35 containing piston 36 which moves bearing 31 to the left against the Belville washers to release pressure on the splines and allow the stem to be rotated and then removed. The valves 70, 71, 74 &c. may be operated manually or by an automatic servomotor control means. In an alternative embodiment, Fig. 4 (not shown), the bearing 39 is rotatable instead of the stem. In other embodiments, the splines are omitted and the bearing 31 has a plain bore, Figs. 5, 6 (not shown), or the enlarged head of the stem is detachable therefrom, Figs. 7, 8 (not shown). In a further embodiment, Fig. 9, the plungers 22 are pressed inwardly by springs 60 and are retracted by pressure fluid admitted through a conduit 63. Upon retraction a port 65 is opened and the pressure fluid passes through pipe 66 to act on the piston 36. The plungers 22 may alternatively be operated by eccentrics or toggles. A detachable lifting-gear 57, Fig. 7 (not shown), may be provided for the pressing stem. The invention may also be used in a forging, piercing or drawing press.
