IPC: C08F255/02
Filed: 1964-06-07
Abstract: 1,054,062. Vinyl chloride graft polymers. MONTECATINI SOCIETA GENERALE PER L'INDUSTRIA MINERARIA E CHIMICA. June 8, 1964 [June 17, 1963], No. 23594/64. Heading C3G. Graft polymers are made by polymerizing vinyl chloride at between 0‹ and 90‹ C. in the presence of a radical initiator and an amorphous linear polymer having head-to-tail structure and a molecular weight between 1000 and 500,000 which is a homopolymer of an olefin of the formula CH 2  = CHR in which R is an alkyl group, a copolymer of such olefins with each other and/or with ethylene, or a terpolymer of such an olefin with ethylene and a dienic hydrocarbon. The preformed polymer used may be one which has been cross-linked by treatment in aqueous emulsion with a peroxidic cross-linking agent. The graft polymerization may be carried out either by suspending in water a solution of the preformed polymer in vinyl chloride, which is then polymerized, or by making a latex of the preformed polymer in which the vinyl chloride is polymerized. The examples describe the graft polymerization of vinyl chloride and (1) an ethylene-propylene copolymer, (2) an ethylenepropylene-cyclopentadiene terpolymer, (3) an ethylene-butene-1 copolymer, (4) an ethylenepropylene copolymer, (5) across-linked ethylenepropylene copolymer, (6) a cross-linked ethylenepropylene-cyclooctadiene, and (8) a cross-linked ethylene-butene-1 copolymer.

Title: Process for the manufacture of azodyestuffs
IPC: C09B43/11
Filed: 1934-08-16
Abstract: Azo dyes derived from 2 : 2<1>-diaminodiaryl compounds are made by treating mono- or poly-azo dyestuffs containing at least once the grouping <FORM:0442879/IV/1> in presence of a non-caustic alkaline acid-binding agent with copper or with cuprous compounds or with copper in combination with cuprous compounds at elevated temperature. The reaction is accelerated in the presence of nitrogen containing bases.  They are suitable for dyeing wool and silk.  In examples: (1)--(3) the dyestuff 2-chloraniline-4- or 5-sulphonic acid --> b -naphthol is heated in aqueous solution with sodium carbonate and copper powder, or with methylamine or ammonia, copper powder and/or cuprous chloride, or with sodium carbonate, pyridine and copper powder or cuprous chloride; the dyestuff o-chloraniline --> 2-naphthol-6-sulphonic acid and 3 : 3<1>-dichloro-4 : 4<1> - diaminodiphenyl \sQ 2 - naphthol - 5 : 7-disulphonic acid may also be treated; (4) the dyestuff 1 - chloro - 2 - naphthylamine - 7 - sulpho acid --> b -naphthol is heated with pyridine, sodium carbonate and copper powder; (5) the dyestuff 1 -chlor-2-aminoanthraquinone --> 2-naphthol-6-sulphonic acid is treated with pyridine, potassium bicarbonate and copper powder in aqueous solution; the dyestuff obtained yields flavanthrene on reduction; (6) the dyestuff 2-chloraniline-5-sulphonic acid --> p-cresol is treated as in (4). The dyestuffs generally yield the corresponding diamino diarylsulphonic acids on reduction.

Filed: 1960-07-07
Abstract: 989,094. Wrapping-machines. H. HARDY. Sept. 20, 1961 [July 7, 1960], No. 23806/60. Heading B8C. Apparatus for dispensing and wrapping quantities of a flowable material such as salt comprises a main frame supporting a material container, a conduit extending therefrom to a hopper with a valve-controlled release, mechanism to feed a paper strip step by step to a position below the release, means for severing a predetermined length of the strip, means for forming the paper to a cup-like container with the material therein, means to crimp the container neck to enclose it about the material, and a power unit to control the valve, paper strip feed mechanism, severing means, and crimping means. The material passes from a container 11 on a main frame 8 through a tube 12 to a channel shaped hopper 13, which constitutes a plunger type multiple valve carrying tubular plungers 25 arranged in line, and operates in conjunction with a series of valve rods 55 which are each closed against the action of a spring 56 when the hopper moves upwards. A plurality of paper strips 14 from rolls 15 are fed over a crimping mechanism and below the hopper 13 by a pair of rollers 16, 17, the roller 16 being resiliently pressed on to the roller 17 by compression springs and the roller 17 being driven by a sprocket wheel 18 through a free wheel mechanism by a chain 19 which is spring- loaded, so that when the rollers have fed the strips forward a predetermined amount between lateral side guides 28 the free wheel action of roller 17 permits the chain 19 to return. The strips are pushed through holes 26 in a valve plate 27 by the plungers 25 and into position for crimping, together with a quantity of the material, being cut into lengths by a guillotine 29 on the hopper 13 as it descends. Crimping is effected by two pairs of plates 41-44 having pear-shaped apertures 53 which move in opposed directions into the position of Fig. 5 to seal the paper into packets which, when the crimping plates move back under the action of springs, fall down a shoot 54 into a receptacle. Hopper 13 moves up and down with a member 38 operatively connected to bars 34, 35 and rods 32, 33 upon rotation of eccentrics 30, 31 on the shaft 10. The crimping plates 41-44 are moved from side to side by rockers 46, 47 connected to springs 52 and to cam followers 48, 49 respectively.

Title: Production of finely divided titanium dioxide
IPC: C01G23/07
Filed: 1950-09-29
Abstract: Pigmentary titanium dioxide is produced by discharging a uniform pre-mixture of titanium tetrachloride vapours, gases containing free oxygen, and a volatile silicon compound in amount sufficient to yield a product containing 0.01-10 per cent silica, into a combustion zone, suitably at a linear flow rate of 1-50 metres per second, the mixture being at a temperature of 135-500 DEG C, and continuously contacting the premixture with an auxiliary flame sustained by a separate inflow of combustible gas to ignite the premixture and maintain it at a flaming state. Suitable silicon compounds are silicon tetrachloride, -hexachloride, -tetra-bromide, -chloroform, or -tetraethyl ester, chloromethyl silicane, dimethyl silicane, tetraethyl silicane, silicon hydride &c.  The silicon compound may be added to the silicon tetrachloride to be vaporized, e.g. by passing oxygen-containing gas therethrough.  Alternatively, the vapours may be mixed, the silicon tetrachloride, say, being produced by passing chlorine, with or without a diluent, over heated silicon. The premixture should contain at least 50 per cent, up to a surplus, of oxygen, for the decomposition of the titanium tetrachloride.  Inert gas such as carbon dioxide or nitrogen may also be present.  Methane, acetylene, hydrogen &c., or preferably, carbon monoxide, are employed as combustible gases.  Temperatures of 750-1200 DEG  C immediately ambient to the auxiliary flame are specified.  Examples disclose burners consisting of three concentric tubes, the titanium tetrachloride &c., premixture being passed through the central tube, and the combustible gas and oxygen for its combustion being passed through the outer tubes. The product, which is largely anatase with a content of rutile varying with the reaction conditions, may be subjected to evacuation to remove chlorine and hydrogen chloride, and neutralized with a small amount of lime.
