Title: Production of aromatic halogen substances
Inventor: MCCALL ERNEST BRYSON
IPC: C07C17/26
Filed: 1962-02-28
Abstract: Fluoroaryl groups are introduced into aromatic compounds by treating them with nuclearly fluorinated aromatic compounds substituted in the nucleus with one or more sulphonyl halide groups, sulphonic acid groups or sulphonic acid salt groups which decompose at the reaction temperature. Specified aromatic compounds into which fluoroaryl groups may be introduced are benzene, naphthalene, diphenyl, diphenyl ether, m-diphenoxy-benzene, dibenzothiophene, dibenzofuran, 2-methyl-2-phenyloctane, chlorobenzene, m-difluorobenzene, o-dichlorobenzene, p-dibromobenzene, 1,3,5-trichlorobenzene, 1,2, 4,5-tetrachlorobenzene, 1,2,4,5,6-pentachlorobenzene and tetraphenyl orthosilicate.  Mention is made also of aromatic compounds substituted with an alkyl, cycloalkyl or aralkyl group, an alkoxy group, a carbonyl group or a carboxylic ester group. Heterocyclic compounds containing nuclear nitrogen, e.g. pyridine or quinoline, may also be treated, but in this case side reactions are likely to occur.  Specified fluoroarylating agents are 4-fluorobenzene sulphonyl chloride, 3-fluoro-4-methylbenzene sulphonyl chloride, 3,4-difluorobenzene sulphonyl chloride, 3,4,5-trifluorobenzene sulphonyl chloride, pentafluorobenzene sulphonyl chloride and bromide, pentafluorobenzene sulphonic acid, tetrafluorobenzene 1,3-disulphonyl chloride, heptafluoronaphthalene-1-sulphonyl chloride and ammonium fluorobenzene sulphonate.  Mention is made also of fluoroarylating agents containing also other halogen atoms or an alkyl or a nitro group. The reaction may be effected at 200-400 DEG C. in the liquid or vapour phase under atmospheric or raised pressure, optionally in the presence of a solvent and a catalyst, e.g. a catalyst described in Specification 959,605. An example is given in which 1,3,5-trichlorobenzene is heated at 210 DEG C. with pentafluorobenzene sulphonyl chloride to yield 2,4,6-trichloro-21,31,41,51,61 -pentafluorodiphenyl. Other specified products are 2-bromo-21,31,41-trifluorodiphenyl, 2-chloro-21,31,41,51-tetrafluorodiphenyl, 2,5-dibromo-21,31,41,51,61 -pentafluorodiphenyl, 2,4,6-, 21,31,41,51,61-octafluorodiphenyl, 2,4,6-tribromo-21,31,41,51,61 -pentafluorodiphenyl and 2,3,5,6-tetrachloro-21, 31,41,51,61-pentafluorodiphenyl. The substituted diphenyls in which one phenyl nucleus contains 3, 4 or 5 fluorine atoms and the other contains 1-5 halogen atoms, which may be chlorine or bromine atoms, are claimed as new compounds.

A pneumatic tyre carcase is formed of parallel cord fabric plies 1, 2 disposed to provide a central crown portion C, D wherein the cords of the ply or plies extend geodetically along a single direction which is other than 90 degrees to the circumferential direction, and two lateral portions comprising the beads and side walls of the carcase wherein the cords of the plies are in crossed relation, said central portion extending for not further than the points in the side wall defining the maximum axial width of the tyre, and not less than one-third the axial width a, b of the tread. The carcase may comprise a single ply 1 of bias cut parallel cord fabric anchored at its side edges to each bead 3, and two strips of such fabric anchored one to each bead 3 and laid with their cords crossing those of the ply 1. Alternatively, the strips 2 can be replaced by the extended turnedup edges of an extended width ply 1. Where more than one extended ply, or side strip 2 is used, their edges may terminate in staggered relation. Such a carcase may be provided with a breaker of one or more layers of parallel cords disposed with their cords parallel to, or crossing those of the crown portion of the carcase ply, the breaker being applied to the carcase after shaping thereof in order not to interfere with the geodetic deformation of the carcase cord paths during shaping. Fig. 3 shows in full lines the paths assumed by the carcase cords in the crown portions C, D and sidewall portions A, C and F, D, with the actual cord paths of a shaped conventional cross-ply carcase being shown in broken lines.

[Class 103 (i)] [Also in Group XXIV] The transmission of the operating forces to the parts of a brake device is effected from both ends of a rotatable sleeve which is both driven and oscillatably mounted at substantially the centre of its length whereby the forces are equalized. A brake for accelerating the gearchanging operation in gear-wheel change-speed gears of motor vehicles is shown and comprises a non-rotatable friction ring 5 adapted to engage the interior surface of a gear-wheel 2. A spindle 9 mounted in a cover 10 secured to the gear-casing 1 has a toothed end portion 91 which loosely engages a corresponding portion at the middle of a sleeve 8 provided with cams 7 which when the spindle is turned by the arm 13 act on sliding pins 6 to apply the brake. The sleeve 8 can also rock on a part-spherical bearing 15 to ensure equalization of the pressure applied to the two pins. The spindle is pressed against the packing 12 by a spring 11. Rotation of the ring 5 is prevented by the engagement of tooth-like projections 17 on a fixed ring 16 with stops on the ring 5 or the ring may be secured to the pins 6.

Abstract: 104,979. British Thomson-Hoitston Co., (General Electric Co.), June 8, 1916. Systems for continuous-current motors only. -In systems where the field strength is reduced when a predetermined motor speed is reached, means are provided to prevent the field reduction from taking place until the starting-resistance has been cut out from the circuit. The motors 1, 2 are supplied through the trolly 4, and the controller 5 may be operated to give the usual series-parallel connexions. Switches 14, 15 are arranged to connect resistances 19, 20 across the field coils 21, 22, and their operating-windings are connected across one of the motor armatures when the switch 11 is closed. This switch has two windings 6, 7, and while any of the starting-resistance 10 is in circuit, both of the windings are energized to hold the switch 11 open. When the starting-resistance is cut out from the series or parallel connexion, the coil 7 alone is energized, and as the motor current drops, the switch 11 closes to connect the windings of the switches 14, 15 across the armature 1. As the motor speed rises to a predetermined speed, the switches 14, 15 close to shunt the field coils. The switches may cut out turns of the field coils and may be arranged to operate only when the motors are in parallel.
