Title: Process for the polycondensation of terepathalic acid diglycol ester
IPC: C08G63/81
Filed: 1953-12-22
Abstract: The process claimed in the parent Specification for the solvent polycondensation of terephthalic acid diglycol ester is modified by performing the polycondensation in a mixture of (a) one or more of the solvents disclosed in the parent Specification, and (b) one or more swelling agents and/or non-solvents for the terephthalic acid diglycol ester and for the polycondensate formed which are able to distil over as an azeotropic mixture with the glycol that is split off.  Polycondensation is preferably effected at 200-240 DEG  C. Specified non-solvents are paraffin hydrocarbons of b.p. of 140 DEG -240 DEG  C., benzine fractions having a high proportion of paraffin hydrocarbons and naphthenes and a b.p. of 140 DEG -225 DEG  C., and xylol.  In an example a mixture of terephthalic acid diglycol ester, methyl naphthalene, xylol and lead acetate (as catalyst) is heated to 208 DEG -210 DEG  C.  The xylol is removed from the azeotropic mixture of glycol and xylol which distils off and is returned to the reaction.  After completion of the reaction, the polyethylene terephthalate is comminuted and extracted with acetone.

Abstract: 344,048. Rail-or-road vehicles. MONCRIEFF, A. H. D., Windsor House, Victoria Street, and SHEARMAN, J., 93, King Henry's Road, Hampstead, both in London. Nov. 29, 1929, No. 36723. [Classes 103 (vi) and 108 (ii).] Non-self-propelled vehicles, for example trailers, are fitted with rail wheels which are fitted as principal wheels having outside them road wheels which are attached to or disposed on hubs secured to or formed as part of the rail wheels. The road wheels are adapted to be moved into or out of eccentricity relative to the rail wheels. Figs. 1 and 2 show a rail wheel in use, with its co-operating road wheel in the raised inoperative position. The rail wheel 2 is bolted to a sleeve 6 which rotates, through the medium of opposed taper roller bearings 5, on the end 4 of a tubular axle which supports the weight of the vehicle. The axle 3 is connected by splines 4<1> to a dog 10 bolted to the sleeve 6. Mounted on the outside of the sleeve 6 is an eccentric 7 which bears in an eccentric opening 8 in the road wheel. When the two eccentrics are in opposition, the road wheel 13 and the rail wheel 2 are concentric and as the road wheel is of larger diameter the rail wheel is raised clear of the road. The two eccentric members are then coupled rigidly to the rail wheel and to the driving element 10 by long bolts 11, 12 inserted into holes 17, 18 in the dog 10. When the road wheel is out of action the two eccentric members are held in their raised position by means of the bolts 11, 12 which then enter screwed holes in a hinged bracket 22 depending from the vehicle frame. Means, for example a spring plunger, may be provided to assist in locating the eccentrics, additional spring bolts may be used in conjunction with the bolts 11, 12 and the wheels are made interchangeable for the purpose of tyre repair. The rail wheels may be fitted with braking and steering mechanism. In a modification, Figs. 5 and 8, the road wheel 14 is, when in use, keyed to the rail wheel concentrically by means of projecting keys 10 fitting in recesses or abutments 13. A slot is provided in the road wheel, and a loose piece 7 holds it concentric with the rail wheel. When the vehicle is running on rails, as shown in Fig. 8, the road wheel is moved outwards clear of the keys, and the loose piece 7 removed and replaced in the reverse way after lifting the road wheel. Means are provided for holding the road wheel in its raised position and a coarse thread or springs or a cam mechanism may be provided for disengaging the road wheel from the rail wheel. For short journeys on rails the two wheels may be kept concentric, in which case, ramps are provided for lifting one road wheel clear at points, crossings, etc. Specifications 324,859, [Class 100 (iv), Typewriters &c.], and 326,935 [Class 108 (ii), Road vehicles, Undercarriage details &c. for], are referred to.
