Title: Arylation of silicon containing aromatic compounds
Inventor: MILLWARD BRIAN BEARD
IPC: C07F7/02
Filed: 1961-10-17
Abstract: Silicon containing aromatic compounds are arylated in the aromatic group by heating with an aromatic compound having linked to a nuclear carbon atom a sulphonyl halide group, a sulphonic acid group, or a sulphonic acid salt group which decomposes at the reaction temperature. The process is carried out at temperature above 125 DEG C. and a perhalogenated compound, e.g. hexachlorobenzene, may be used as solvent.  In addition, a catalyst as disclosed in Specification 959,605 may be used.  The molar ratio of starting material to arylating agent is preferably 25:1 to 2:1 but an excess of arylating agent may be used to arylate in more than one position.  Silicon containing aromatic compounds used are, silanes; polysilanes; substituted silanes, e.g. halogenosilanes, silicates and siloxanes; and include compounds containing phenyl, naphthyl, furyl, thienyl pyridyl or aryloxy groups which may have as substituents alkyl, cycloalkyl, aralkyl, alkoxy halogen or carboxylic ester groups.  The silicon compounds may also contain a non-aromatic group directly attached to the silicon atom. Specified examples are tetraphenyl orthosilicate; tetra-o-tolyl orthosilicate, tetra-(p-chlorophenyl) orthosilicate; tetra-(3-phenoxyphenyl) orthosilicate, triphenylsilane, diphenyl di(3-phenoxyphenyl) silane, phenyl-2-thienyl di (2-phenoxyphenyl) silane, m-di (triphenylsiloxy) benzene, triphenylchlorosilane; triphenylbromosilane; phenyl-2-thienyldichlorosilane, tri (p-tolyl) chlorosilane; hexaphenylcyclotrisiloxane, phenylsilicone, tolyl silicone xylyl silicone and naphthyl silicone.  The arylating agent may contain one or more sulphonyl halide, sulphonic acid or sulphonic acid salt groups attached to an aromatic radical e.g. phenyl, alkylphenyl chlorophenyl nitrophenyl, pyridyl, naphthyl, benzothienyl, dibenzothienyl, quinolinyl or an aromatic radical containing a furyl thienyl or pyridyl radical.  Such radicals may have as substituents an alkyl, cycloalkyl, aryl, halogen, nitro, carboxylic ester alkoxy or aryloxy group.  Examples of arylating agents given are benzene sulphonyl chloride, toluenesulphonyl chloride, isopropylbenzenesulphonyl chloride, t-butylbenzenesulphonyl chloride, p-nitrobenzene sulphonyl chloride, pyridine 3-sulphonyl chloride, p-phenylbenzene sulphonyl chloride; benzenesulphonyl bromide; m-benzenedisulphonyl chloride, 4,41-diphenyldisulphonyl chloride, benzenesulphonic acid, naphthalenesulphonic acid and ammonium benzene sulphonates.  The examples describe the preparation of mixtures of (1) diphenylyl phenyl silicates from tetraphenyl orthosilicate, (2) diphenylylphenylchlorosilanes from triphenylchlorosilane, (3) diphenylylphenyldichlorosilanes from diphenyldichlorosilane and (4) diphenylyltrichlorosilanes from phenyltrichlorosilane, using benzene sulphonyl chloride as arylating agent.

Abstract: 990,589. Tunnel kilns. SHELLEY ELECTRIC FURNACES Ltd., and D. P. SHELLEY. Oct. 8, 1963 [Oct. 9, 1962], No. 38117/62. Heading F4B. [Also in Division B8] A kiln for firing ceramic and glazed-ware in which two streams of goods are passed therethrough in opposite directions supported on cushions of heated air, is formed by a number of identical units defining a common tunnel 11, each comprising two perforated hearths 17a, 17b sloping in opposite directions through which air, previously drawn over gas, oil or electric heating elements 16, is upwardly-flowed by a water-cooled, recirculating fan 31 to provide supporting aircushions beneath the throughput goods-carrying batts 22. The propulsion of the two contraflowing streams of goods through the kiln is initiated by the input conveyers 32 and maintained by the opposed down gradients of the respective hearths as illustrated in Fig. 4 (not shown). The incoming goods of each stream are heated progressively to a maximum by the circulating air, which absorbs heat both from said elements and the contra-flowing other stream of heated outgoing goods, and are subsequently progressively cooled by said air transferring heat to the contra-flowing incoming goods of the other stream. Each unit, which is mounted at 14 on a common rail track to permit ready replacement of a faulty unit, is provided with perforated side panels to allow air to circulate above the goods and with downwardly-dependant baffles 50 to restrict air flow between adjacent units. Upstanding guide members cemented along the edges of the hearths prevent lateral movement of the batts, or alternatively, as in Fig. 9 (not shown), the batts and hearths may be correspondingly formed with mating, self-centring shallow V- shaped or convex-concave profiles. In a further modification when the goods are not mounted on batts, being in the form of tiles or the like, deflector members inwardly direct jets of air to control lateral movement of the goods as illustrated in Figs. 7 and 8 (not shown). More than two streams of goods in more than one layer may be provided.

Abstract: 1,271,277. Bank note counter. GOVERNOR & CO. OF BANK OF ENGLAND. 4 Aug., 1970 [4 Aug., 1969], No. 38963/69. Heading G4D. A banknote counter as described in Specification 1,048,411 is modified as indicated below. The machine counts banknotes or other valuable documents which should be in bundles of 100, sends the bundles having the correct number of notes to another department or to an incinerator, returns the bundles having the incorrect number to the operator, and records the number of bundles in each category. Operation.-An operator enters a personal aluminium template, and a personal number on knob 13, and enters a first bundle of notes (held inside a paper band) between plates 14, 15 of a loading device 23 which inserts the bundle between one (18) of three sets of jaws of a rotatable clamp unit 17. When the jaws have gripped the bundle, device 23 withdraws, and a pneumatically operated guillotine 22 cuts off the ends of the notes thus leaving a clean edge for counting. The operator's personal number is printed on the band and the clamp is rotated by 120 degrees to present the clean edge to a counter 16 (as described in Specification 887,703) where the notes are counted. Simultaneously a second bundle may be loaded into jaws 19, guillotined, printed and fed to the counter when the clamp is rotated a further 120 degrees. The first bundle actuates switch 25 (if it is correct) to record on a paper roll, and in either case the jaws release the bundle into box 139 whence it is passed to the appropriate destination, respective counters recording the respective numbers. A visual display 167 monitors progress and double locks prevent a correct bundle being retrieved by an unauthorized person. Modifications.-Each set of jaws is arranged so that it can be rotated pneumatically so that the bundles can be dropped vertically (i.e. short edge first) into the box 139 which is provided with a movable lid (Fig. 9, not shown). The box itself is rotatable. The counter can be replaced (Fig. 17, not shown) by a modified counter.

Abstract: 1,000,261. Embossing. DUNBEE-ELM Ltd. Oct. 31, 1961 [Oct. 31, 1960], No. 38988/61. Heading B5A. [Also in Division B6] A thermoplastic material is embossed to give a suede-like finish by pressing it against a hard embossing surface, the surface to be embossed and the other surface being wetted with liquid which is respectively relatively hot and relatively cold. As shown, vinyl plastic film or sheet 12 is fed between a heated, engraved embossing roller 10 and an unheated, rubber-surfaced impression roller 11. Troughs 14, 15 are mounted adjacent to the nip of the rollers and water is fed into the troughs through pipes 19, 20 respectively so that the water overflows from the troughs and wets both sides of the film 12 as it enters the nip of the rollers. The embossing roller is maintained at 325‹ F., the water in the trough 14 is heated to 85‹ F. and the water in the trough 15 has a temperature of 35‹ to 40‹ F. The temperature of the heated water may range from 70‹ to 150‹ F. and the difference in temperature between the two lots of water may range from 10‹ to 110‹ F. The liquid may be any, preferably volatile, liquid which is substantially inert with respect to and a non-solvent of the material being embossed, e.g. water, aqueous solutions containing surface-active organic materials which serve as " wetting agents," kerosene, the relatively high-boiling, non-viscous light lubricating oil fractions, alcohols, esters and fusel oils. A hydrophobic, surface-active material, e.g. silicon, may be coated on the embossing surface before use. The liquid may be applied to selected portions only of the material to be embossed with the result that the improved embossing effect is obtained at these areas only. Two embossing operations may be effected on the material to be embossed, the first embossing being so effected as to have a layer or film of the liquid in certain depressed portions of the design and the second embossing being particularly directed towards these depressed portions. Alternatively, the first embossing may be " dry," the liquid being applied between the two operations. In a modification the machine may be of the platen-type.
