Title: Improvements in the manufacture and production of soluble polymerisation products from diolefines
IPC: C08F36/04
Filed: 1929-03-15
Abstract: 333,872. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 15, 1929. Caoutchouc, synthetic.-Readily soluble polymerization products of diolefines are produced by effecting the polymerization in presence of alkali or alkaline earth metals previously dispersed in solvents or dispersion media. The dispersions may be made by comminuting the metals in the liquids while stirring or shaking, preferably while heating, or by atomizing fused sodium into the liquid through a nozzle. The liquid dispersion medium may be a hydrocarbon such as benzene, toluene, xylene, tetrahydronaphthalene, decahydronaphthalene, hexahydrobenxene, paraffins such as benzine, or the liquid polymerization product of the process. The diolefine may be led into the dispersion in the form of vapour ur liquid, and the diolefine or the dispersion may be continuously introduced and the product continuously withdrawn. The process may be effected at ordinary reduced, or increased pressure, and the solvent may be wholly or partly distilled off during or after the process. Cooling may be applied to remove the heat evolved, or the diolefine may be diluted with inert gas such as nitrogen, argon, or hydrogen. The products are viscous to tenacious in character and only slightly elastic. In the examples (1) sodium is comminuted in decahydronaphthalene at 140‹ C. and butadiene vapour is led into the dispersion which has been cooled to from 60‹ to 100‹ C.; when the absorption ceases, the sodium is destroyed by alcohol, and the mixture is treated with steam, leaving a sticky white mass which when dried in vacuo is a transparent viscous liquid soluble in benzene, amyl acetate, pyridine, benzine etc.; (2) potassium and sodium are comminuted in dry xylene at 130‹ C. and butadiene is led in, the temperature being kept at 60-80‹ C. by cooling or adding nitrogen to the butadiene or both; when the absorption ceases, the mixture is diluted with benzene, the alkali metals destroyed by alcohol, and the whole is filtered to remove any insoluble bye-product, after which the solvent may be removed by distillation. Specifications 22137/13 and 320,362 are referred to.

Title: Carbon articles
IPC: C01B31/00
Filed: 1970-02-23
Abstract: 1352141 Fibre reinforced carbon bodies NATIONAL RESEARCH DEVELOPMENT CORP 19 April 1971 [23 Feb 1970 17 Aug 1970] 8532/70 and 39541/70 Heading C1A A carbon article is produced by impregnating with synthetic organic resin an assembly of polyacrylonitrile fibres which fibres have been previously partially converted into carbon fibres, the impregnated body then being carbonized at a temp. of at least 1000‹ C. The polyacrylonitrile fibres used are those capable of conversion to high strength, high modulus carbon fibres. The partial pyrolysis may include heat treatment at a temp. of 200-250‹ C. in an oxidizing atmosphere whilst the fibre is restrained from shrinking. The partial pyrolysis of the polyacrylonitrile may also include heat treating in an inert atmos. at a temp. up to 600‹ C., e.g. in the region of 400‹ C. A rod or fibre shaped body may be produced by impregnating a tow of the fibre, shaping the impregnated tow into a body and carbonizing. The shaping step may be achieved by drawing through the die and rods having diameters of 100-500 microns may be produced. The resin used may be phenol-formaldehyde, polyvinylindene chloride, and polyfurfuryl alcohol. The resin or the fibre may include a finely divided inert filler, the preferred filler being finely divided carbon, e.g. carbon black.

Title: Improvements in and relating to the production of crimped threads or filaments
IPC: D02G1/10
Filed: 1942-06-26
Abstract: 558,297. Crimping filaments and threads. IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 26, 1942 No. 8784. Convention date, June 27, 1941. [Class 120 (iii)] Continuous untwisted filaments or threads are crimped by passing them over a deforming edge while under tension with a substantial charge in the direction of the thread in its passage over the edge and subsequently relaxing the thread ; the crimped thread may be cut into short lengths and may comprise a "nylon" and a slightly twisted yarn e.g. one with no more than two per inch may be used to obtain an intermittent rather than a continuous crimp. As shown an untwisted continuous thread or filament 2 e.g. of nylon, is taken by rollers 5 from a supply bobbin 1, or from the rollers used in cold drawing the initially-formed filament, is passed around a tension device 3 and then around the edge of a member 4 where the thread has a change in direction of 90 degrees ; after passing the rollers 5, the relaxed and crimped thread is cut by a device 6 into staples of any desired length or the thread may be cut before it is relaxed. The relaxed thread may be wound up on a bobbin or other collecting device, the crimped thread may be twisted while still under tension, may be abraded to cause a random breakage of the filaments of the thread, and the crimps may be set by a steaming or other process. The thread may be passed around the edges of a rectangular member to give a change in direction of 170 degrees or a change of 45 degrees may be given by passing it around a right-angled edge.

Title: Improvements in or relating to serines
Filed: 1956-03-26
Abstract: Serines are manufactured by reacting glycocoll with a substantially equimolar quantity of glyoxylic acid or an ester or ester-semiacetal thereof with a C1-4 aliphatic alcohol, condensing the resulting Schiff's base with p-nitrobenzaldehyde or a quinoline aldehyde in the presence of at least one alkali metal hydroxide and/or alkaline-earth metal hydroxide, and decomposing the product with a dilute acid to yield p-nitrophenylserine or a quinolylserine.  The first step is advantageously carried out in a solvent (e.g. water or a mixture thereof with one or more lower aliphatic alcohols) at room temperature or moderately elevated temperature (e.g. 40-70 DEG  C.) and in the presence of a condensing agent (e.g. as for the second step).  The Schiff's base may be used without isolation in the second step, for which a moderately high temperature is desirable.  In examples, in each of which dilute sulphuric acid is used for the final acidification, the following condensations are effected: (1) glycocoll with glyoxylic acid ethyl ester ethyl semiacetal in aqueous caustic potash and the product with p-nitrobenzaldehyde in aqueous methanol in the presence of calcium acetate and calcium hydroxide; (2) glycocoll with glyoxylic acid monohydrate in milk of lime and the product with p-nitrobenzaldehyde in aqueous methanol in the presence of calcium hydroxide; (3) glycocoll with glyoxylic acid ethyl ester and the product with p-nitrobenzaldehyde, both steps as in (1); (4) as in (1) except that the aldehyde used in the second step is quinolyl-aldehyde-(2).
