Title: Manufacture of polysulphones
Inventor: JONES MICHAEL EDWARD BENET
IPC: C08G75/20
Filed: 1964-08-06
Abstract: Polyaryl sulphones containing repeating units -Ar-SO2- are obtained by polymerizing a compound of formula H-Ar-SO2.X and/or a mixture of compounds of formulae X.SO2-Ar-SO2X and H-Ar-H, where X is a halogen atom and Ar is a divalent aromatic radical, at a temperature up to 160 DEG  C. in the presence of a Lewis acid catalyst and in solution in a nitrobenzene of formula <FORM:1109842/C3/1> where A1 is a hydrogen or halogen atom or an alkyl, cyano or nitro group and A2 is a hydrogen or halogen atom or an alkyl group.  In at least some of the units of the polymer Ar is derived from a compound of formula <FORM:1109842/C3/2> (where Y is -O-, -S- or the residue of a 4,41-bisphenol) by the loss of a hydrogen atom from each benzene ring, and in any other units Ar is derived from benzene, biphenyl or an aromatic hydrocarbon containing not more than two aromatic nuclei. From 0.75 to 3 parts by weight of the nitrobenzene may be used per part by weight of polymerizable compounds.  In examples polymers are obtained from diphenyl ether 4-sulphonyl chloride, from diphenyl ether and diphenyl ether 4,41-disulphonyl chloride, from 1,2-diphenoxyethane and diphenyl ether 4,41-disulphonyl chloride, from dibenzofuran and diphenyl ether 4,41-disulphonyl chloride, from dibenzofuran and diphenyl 4,41-disulphonyl chloride, and from diphenyl ether and diphenyl 4,41-disulphonyl chloride; the monomers are dissolved in nitrobenzene and the catalysts are ferric chloride and antimony pentachloride.

Abstract: 209,562. Smale, S. R., Ashby, T., and Galley, R. J. Nov. 24, 1922. Race games.-Relates to game apparatus of the type in which a vertical shaft carries a frictiondriven device having a series of radiating arms from which figures are suspended so as to be under the influence of electromagnets which are energized by the competitors with the object of arresting any particular figure and stopping the movement of the radiating arms. The invention consists in the provision of controlling means whereby the magnets are energized in varying degrees by cutting in or cutting out electrical resistances in an electric-supply circuit. The apparatus comprises a spindle i driven from a hand-wheel e by gears g, h, and carrying a spindle k on which weights m are adapted to slide by centrifugal force against the pressure of light springs n. The discs o may be adjusted on the spindle k to vary the pressure of the springs n. Each weight m carries a spring-pressed bush p which contacts with studs t on a porcelain or like insulated base q, on which resistance wires r are wound. Tappings s are taken to the studs t and collectors u are coupled to the lead wires, as shown in Fig. 3. The greatest energization of the magnet v occurs when the weights m are about mid-way of their travel. The apparatus may be employed with other game apparatus, such as apparatus in which the figures to be arrested by the magnets are caused to move along circular or other tracks, as described in the Provisional Specification. The figures may then be arranged to form a race game and may be illuminated when they are arrested.

Disc recording apparatus.-In an instrument in which a temporary record is produced by pressing a marking point on to a record surface and the record is subsequently effaced automatically as described in the parent Specification the record surface, according to the present invention, is constituted by a layer of grease and the groove produced by the marking point is effaced mechanically by a smoothing body. In the form shown in Figs. 1, 2, and 4, an annular disc c is secured to a ring d having teeth engaging a worm (not shown) connected to an operating member of the instrument. The disc c is rotatably supported in a profiled ring a under a covering disc b and is provided on its under surface with a layer f of a plastic substance such as cattle hoof fat with a colouring pigment such as Kremnitz white. The ring a carries a bottom covering disc e to form a closed casing which may be fitted into an instrument by press buttons n. The disc e is provided with a radial slot forming a guide for the resiliently mounted marking member g. The effacing of the record is effected by a roller or rollers h, i adapted to be rotated by gearing h<1>, i<1>, and k from a spindle k<1> connected with the teeth of the ring d. The roller h is pressed against the disc c and smoothes out the record line by causing the mass to pass around the rollers i and h before again being pressed on to the disc c. The rotation of the roller h is preferably contrary to that of the diso c, and it may be given an axial movement so as to distribute the layer uniformly. In a modification shown in Fig. 6, a small trough o with entrance and exit apertures or slits o<1>, o<11>, is arranged below the layer f and a stripper q within the box effaces the record before it is applied at the exit. The trough is held in a yielding manner in a protecting casing l by means of a spring r. The layer may also consist of an organic or artificial substance having soft hairs of such fineness that they are non-elastic throughout and retain the direction given to them by the recording point until removed by a smoothing or brushing device.
