Title: Improvements in the manufacture of bulky yarns
Inventor: JEFFREY GEORGE MALCOLM
IPC: D02G1/18
Filed: 1964-05-19
Abstract: Yarn is formed from at least two staple fibre and/or continuous filament components, one having latent (and perhaps some patent) crimp and the other being heat shrinkable, and a hank of such yarn or a fabric made therefrom is heated e.g. by exposure to super-heated steam, to bulk the yarn and render it extensible as a result of the release, or further or complete developments, of random or regular e.g. helical, crimp and shrinkage in the respective components.  The latent crimp exists as a result of previously crimping the fibre and then temporarily removing the crimp, or by virtue of the bicomponent structure of the fibre. The crimped or crimpable and shrinkable fibres may be of one or more forms of polyacrylonitrile or the former may be of cellulose triacetate or the latter of a polyolefin, polyvinyl chloride, or polyester.  These fibres, which may differ in denier and/or staple length are combined in a loose fibre or sliver blend and then spun and twisted into doubled yarns.

Title: Improvements in the manufacture of gas
IPC: C10J1/213
Filed: 1921-08-02
Abstract: 188,073. Young, D. J. Aug. 2, 1921. Producers; producer plant.-In the production of carburetted water gas m apparatus comprising a producer, a carburettor and superheater steam is periodically passed through the apparatus in the reverse direction, raw fuel being at the same time supplied to the fuel bed and water gas taken off from the bottom of the producer. The producer 1 is blown with air from an inlet 50, secondary inlets 53, 54 providing air for combustion of the gas in the carburettor 2 and superheater 3 respectively, the gases escaping by a stack 32. The air supplies are then cut off and steam introduced through a pipe 62, passing through and being highly superheated in the superheater and carburettor and passing downwardly through the producer, the water gas being taken off by a pipe 8. During this period fresh fuel is charged on to the fuel bed 12 and distilled thereon by the superheated steam, the volatile products mixing with the water gas. When the superheater and carburettor have been somewhat cooled the apparatus is operated in a normal manner with the introduction of steam through inlet 6 or 61, oil through pipe 21, and the withdrawal of gases through pipe 31. Valves 40 and 42 and pipe 41 may be dispensed with leaving a permanently free connection between the generator and carburettor.

Title: Improvements in or relating to high boiling esters of unsaturated aliphatic alcoholsand process of preparing same
IPC: C07C69/83
Filed: 1947-08-05
Abstract: High-boiling esters, i.e. esters boiling above 100 DEG  C. at 1 mm and generally at about 250-275 DEG  C. at atmospheric pressure, of unsaturated aliphatic alcohols with polycarboxylic acids are prepared by esterifying the alcohol with the acid or its anhydride in the presence of a substantial quantity of added diether corresponding to said alcohol.  This reduces the conversion of alcohol to ether. Allyl alcohol, phthalic anhydride, and toluene sulphonic acid may be refluxed until the temperature reaches 120 DEG  C. and the acid ester is formed, a feed mixture of the alcohol, diallyl ether, water, and catalyst then being added to maintain reflux.  The vapours, forming a constant boiling ternary mixture, are condensed, stratified, the upper layer being returned as reflux, and the lower, which is mainly water, withdrawn.  The product is neutralized, stripped, centrifuged, and distilled to give pure diallyl phthalate.  Polyesters of allyl or crotonic alcohol, 4-methylpentene-3-ol-1 or pentene-4-ol-2 with oxalic, malonic, succinic, adipic, sebacic, suberic, citric, fumaric, maleic, terephthalic, phthalic, benzene tricarboxylic, cyclohexane dicarboxylic, pyridine or naphthalene polycarboxylic acid may similarly be prepared.  Other aromatic sulphonic acids including halogenated, nitro or hydroxy sulphonic acids or mineral acids may be used as catalysts.  The amount of added ether may be about 30-50 per cent of the alcohol used.  The water may be removed with excess alcohol or by adding an entrainer which may be diallyl ether itself. The unsaturated alcohol may be recovered or the alcohol-ether distillate from the condensed vapours in the preparation of dially phthalate admixed with fresh alcohol to give the feed mixture.

Abstract: 500,211. Condensation products. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Aug. 4, 1937, No. 21498. [Class 2 (iii)] High molecular woight substances are prepared by reacting halogen derivatives of saturated aliphatic hydrocarbons with vinyl compounds containing at least four carbon atoms in the presence of acid-reacting inorganic halides or of large surfaced substances such as kieselguhr or bleaching earths. Suitable halogen derivatives include methyl chloride, carbon tetrachloride, ethylene chloride and halogenated hydrocarbons derived from petroleum, destructive hydrogenation of coals, tars and petroleum, paraffin wax, petroleum jelly, ceresine or ozooerite, or the benzine synthesis from carbon monoxide and hydrogen; suitable vinyl compounds include styrene, vinyl ethyl, isobutyl or oleyl ethers, vinyl esters, vinylcarbazole, mono- and di-vinylacetylene or mixtures thereof. Solvents, which may take part in the reaction, such as benzene, benzine, carbon tetrachloride, chloroform or ethylene chloride may also be used. The products are soluble in oil and may be used to increase the viscosity and decrease the setting point of lubricating oils. In an example, a chlorination product of hard paraffin wax is reacted with styrene in the presence of aluminium chloride and ethylene chloride to yield a product which may be separated into a light lubricating oil and a highly viscous oil. The Provisional Specification refers in general to the interaction of halogenated hydrocarbons and unsaturated compounds containing four carbon atoms.
