Patent GB-1117327-A (GB)
Title: Poly-(phenylene oxides)
IPC: C08G65/38
Filed: 1965-08-10
Abstract: The invention comprises amorphous poly-(phenylene oxides) containing from 0 to 75 mole per cent para-phenylene oxide units with the remainder being ortho-phenylene oxide units, in which up to 30% of the units may carry the side groups phenyl, carbonylaryl or sulphonylaryl, the polymer having a softening range below 150 DEG C., an inherent viscosity measured as a 1% solution of polymer in sulphuric acid of at least 0.3, complete solubility in benzene at 25 DEG  C., and a temperature of at least 500 DEG  C. for a 10% weight loss in air, as determined by Thermogravimetric Analysis at a rate of temperature rise of 5 DEG  C. per minute.  The polymers are prepared from very pure potassium o- and p-chlorophenolates containing not more than 0.05% of water, in the presence of 0.01 to 0.5 mole per cent of a cuprous or cupric salt and of 2 to 100 weight per cent of pyridine or quinoline, in the absence of oxygen and air, by heating to 160 DEG  to 175 DEG  C. for 2 to 24 hours and then at 200 DEG  to 275 DEG  C. for one or more hours.  The molecular weight of the polymer may be increased by dissolving it in a solvent and oxidizing with sodium hypochlorite or lead tetraacetate, or with oxygen and cuprous chloride or potassium ferricyanide, or with lead dioxide and caustic alkali.  The polymer may be cured by heating with dicumyl peroxide, di-t-butyl peroxide, benzoyl peroxide, lauroyl peroxide or azobisiso-butyronitrile. In examples, the purified potassium salts of p-chlorophenol, o-chlorophenol, 2 - chloro - 4 - phenyl phenol, 2 - chloro - 6-phenyl phenol, 2 - benzenesulphonyl - 4 - chlorophenol and 2 - benzoyl - chlorophenol, are heated in the presence of cuprous chloride and pyridine (in some instances pyridine is present in some of the monomers as pyridine of crystallization); the molecular weight of two polymers is increased by reacting them in solution with sodium hypochlorite and with cuprous chloride and oxygen.ALSO:Polyphenylene oxide polymers containing 0 to 75 mole percent paraphenylene oxide units with the remainder being ortho-phenylene oxide units, in which up to 30 percent of the units may carry the side groups phenyl, carboxyl aryl or sulphonyl aryl, may be coated on metal, ceramic, glass, plastics and laminate surfaces. In an Example a polymer containing 60 percent para- and 40 percent ortho-phenylene oxide units is dissolved in methylene chloride and xylene, t-butyl peroxide is added and the composition is coated on aluminium sheet and heated.

Abstract: 1,145,718. Shutter control mechanisms. FRANKE & HEIDECKE G. m. b. H (trading as ROLLEI-WERKE FRANKE & HEIDECKE). July 31, 1967 [Aug. 27, 1966], No. 34997/67. Heading G2A. The two curtains of a curtain-type shutter are released successively by two cam discs, the second disc having a series of cams which can release the second curtain at different times, the appropriate cam being brought into its operative position by means of an eccentric mounting of the second disc. In Fig. 1, the roller curtains are in their cocked position, with discs 2, 3 being held against rotation by pawls 4, 5. The other ends 6, 7 of the pawls 4, 5 are engaged successively by cam discs 12 and 13 to release the curtains. Disc 13 is connected to disc 12 by a pin-and-slot arrangement 18, 19, but is rotatable on an eccentric 20, itself rotatable on the spindle 21 of disc 12. Disc 13 has a number of cams 14, 15, 16, 17 extending radially by differing amounts, one of which will trip the end 7 of pawl 5 to release the second curtain, so giving a choice of the different corresponding slit widths. The width is set by a lever 22 having at one end a toothed segment 23 which engages in a pinion segment 14 fixed to the eccentric. The other end of lever 22 has a pin 26 which can ride on the edge 27 of a disc 24, or enter into a stepped slot 28 therein, in which latter case eccentric 20 is rotated so as to bring the cams 14, 15, 16, 17 successively into the effective position. Lever 22 is pivoted to a bell crank lever 35 which is spring-urged anti-clockwise so as to urge pin 26 against disc 24. Also pivoted to bell crank lever 35 by a pin 36 is a lever 39, which has a slot 41 in which engages a peg 40 of an escapement. The other arm of bell crank lever 35 has a pin 33 which rides on the rim 32 or stepped part 30 of another disc 29 which is mounted on the same shaft 25 as disc 24. Shaft 25 is turned by a setting knob. The other end 37 of lever 39 is movable into or out of the path of a cam 38 on disc 12. In Fig. 2 (not shown) it is in its inoperative position, i.e. out of the cam path. As disc 29 turns, and pin 33 descends the stepped portion 30, lever 35, and hence lever 39, pivots so that end 37 of lever 39 intercepts the path of cam 38 Fig. 3 (not shown). The running down is hence delayed until the pretimer mechanism acts to disengage lever 37 from cam 38, so permitting the second curtain to be released. On further rotation of shaft 25, and hence discs 27 and 29, pin 33 rides up on to the rim 32 and hence the escapement becomes ineffective Fig. 4. With continued rotation of disc 29, a catch groove 31 therein engages with a peg 42 at the end of a lever 43, so pivoting its other end 44 out of latching engagement with a lever 45. This is now urged by a spring 46 into a position where its other end 47 will intercept the cam 17, so preventing the running down of the second curtain until lever 45 is released ("B" exposure).
