Patent GB-982082-A (GB)
Title: Process for dyeing and padding hydrophobic materials
IPC: D06P1/32
Filed: 1962-08-17
Abstract: Hydrophobic materials are dyed or padded by treatment, one after the other in either order, with (a) primary aromatic amines, or salts or azomethines thereof and (b) compounds of formula <FORM:0982082/D1-D2/1> wherein R is an aromatic hydrocarbon residue containing at least one water-solubilising substituent, X is =O or =N-Cl and the nucleus A may be further substituted.  The examples describe dyeing of polyethylene terephthalate, but the process is generally applicable to, e.g., threads, fibres, foils and ribbons of aromatic polyesters, polyamides, polymethanes, polyvinyl chloride, polyacrylonitrile cellulose esters and polyolefins.  German Specification 1,088,461 is referred to.
Patent GB-402143-A (GB)
Title: Improvements in the manufacture of filaments, threads, yarns, ribbons and like materials made of or containing saponified cellulose esters
IPC: D06M11/38
Filed: 1932-02-19
Abstract: Filaments, yarns, and the like, of organic esters of cellulose, are saponified while being drawn in the form of a warp, web, or sheet of yarns through a bath containing the saponifying agent, by rollers or the like extending over the whole warp, web, or sheet. The saponifying agent may comprise any suitable base in aqueous, alcoholic, or aqueous-alcoholic solution.  When high concentrations are employed, it is advantageous to have present a buffer salt such as sodium chloride, sodium acetate, or a soap. When using alcoholic saponifying media, e.g., methyl or ethyl alcohol, glycols, or glycerine, the saponifying agent may be present in quantity less than is theoretically necessary to produce the desired amount of saponification.  The extent of saponification may vary from 5 to 50 per cent up to substantially complete elimination of the ester groups, according to whether the object is to increase the safe ironing point, confer an affinity for cotton colours, or produce a reconstituted cellulose thread. The filaments may comprise cellulose esters of high viscosity characteristics, for example, in the case of cellulose acetate, viscosities of the order of 30 to 200 or more, as measured by comparing the rate of flow of a 6 per cent solution in acetone at 25 DEG C. against a standard of glycerine as 100.  High viscosity esters of this nature may be obtained by the process of Specification 207,562, [Class 2 (ii), Cellulose &c.].  The filaments may also have undergone a stretching treatment continuously with, or subsequently to their manufacture by dry or wet spinning processes, preferably so as to produce an extension of the order of 200 to 500 per cent or more, and a tenacity exceeding 2 gms. per denier. Examples of such processes are those of Specifications 277,089, 323,790, [Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, and 378,858.  If desired, the filaments may be subjected, before or after saponification, to treatments with shrinking agents as is described in Specifications 380,504, 380,505, and 389,823.  In an example, yarns of cellulose acetate which have been stretched to 500 per cent of their original length are led from a creel through a reed so as to constitute a warp, through nip rollers by which a wetting out liquid is applied, and then over a further roller into a saponifying bath containing caustic soda dissolved in an aqueous solution of sodium chloride or sodium acetate.  In a further example, the yarn in the previous example is replaced by yarn obtained by dry-spinning cellulose acetate having a viscosity of 55.  The first Provisional Specification refers also to Specification 371,461.

Title: Improvements in and relating to conveyer mechanism more particularly adapted for use in furnaces
IPC: F27B9/20
Filed: 1922-11-24
Abstract: 211,583. Alexander, A. E., (Surface Combustion Co., Inc.). Nov. 24, 1922. Charges, conveying. - A conveyer mechanism for feeding articles through furnaces, comprises two reciprocating rails or sets of rails 12, 12<1> formed with teeth, the forwardly-facing surfaces 32 of which are steeply inclined to the length of the rail, while their rearwardly sloping surfaces 41 are more gently inclined. In the furnace shown in which the conveyer mechanism is more particularly adapted for dealing with crank shafts two pairs of rails are provided, one pair being fixed, while the other is slowly reciprocated from a motor through an eccentric and the rocking-lever 25. The fixed rails are preferably anchored at one end only so that they are free to expand and contract with changes of temperature. The crank shafts are placed transversely on the rails at the left hand end and during the conveying- operation the steeply-inclined surfaces of the teeth prevent rearward movement of the articles with respect to the rails, while the more gently inclined surfaces slide under the articles during the relative rearward movement of the rails. The rails are spaced to engage, the crank pins. and when the shaft has two sets of pins A<2>, A<21> out of alignment with one another, the fixed rails engage one set and the moving rails the other. In a modified form the rails have inclines on their lower faces which slide on corresponding inclines on the bearers so that the direction of the reciprocating movement is substantially parallel to the more gently inclined surfaces of the teeth. In the first form the points of the teeth of both sets of rails, and in the second form of the teeth of the fixed rails, may be cut off horizontally as shown at 41<a>.

Title: Processing of oxidation products
IPC: C07C47/04
Filed: 1963-08-14
Abstract: Oxygen-containing compounds comprising an aldehyde containing not more than 4 carbon atoms in the molecule and a carboxylic acid are recovered from an aqueous solution by distilling the solution at substantially atmospheric pressure to separate a fraction up to an overhead temperature in the range 90-97 DEG  C., adding to the residue of the aqueous solution a C1-C4 aliphati alcohol in an amount in excess of that required to form acetate and esters, and subjecting the mixture so obtained to distillation. The process may be used, for example, in the treatment of the mixture obtained by the catalytic oxidation of propylene, butylene or of a higher hydrocarbon or the mixture obtained by the catalytic oxidation of acrolein or methacrolein. Examples are given of (a) the treatment with methanol of the mixture obtained by the catalytic oxidation of propylene after the separation of the acrolein fraction to give a mixture which on distillation yields formaldehyde dimethylacetal, methyl acetate and methyl acrylate; and (b) the treatment with methanol of the mixture obtained by the catalytic oxidation of acrolein, after removal of the acrolein fraction, to give on distillation methyl acetate, methyl acrylate and methylol.

Title: Improvements in the production of methane dithiol and polythiomethylene dimercaptans
IPC: C08G71/00
Filed: 1962-08-23
Abstract: Methane dithiol and mercapto-terminated polythiomethylenes are made by (a) the reaction of 1.75-10 moles of hydrogen sulphide as a liquid with 1 mole of formaldehyde at super-atmospheric pressure and at temperatures of 40-150 DEG C. to give a normally liquid intermediate whose IR spectrum indicates the presence of mercapto and hydroxyl groups, (b) treating this intermediate with an aqueous non-oxidizing mineral acid at a temperature of 25-175 DEG C. at least until the IR absorption characteristics of the hydroxyl group disappear and (c) recovering the bis mercaptan formed of the structure <FORM:0976820/C1/1> where n is 1 or more, corresponding to an average molecular weight of up to about 160. The formaldehyde employed may be in the form of an aqueous solution or paraformaldehyde. The molecular weight of the product tends to increase as the proportion of hydrogen sulphide to formaldehyde increases and as the reaction time lengthens. The intermediate, of which part at least is believed to be of the structure <FORM:0976820/C1/2> is preferably contacted with 4-6N sulphuric or hydrochloric acid. The molecular weight of the resulting dimercaptan can be increased by heating the product in water at neutral pH. The three stages can be combined into a continuous process. In examples stage (a) is carried out in a nitrogen-purged stainless steel bomb at 60 degrees so that an autogenous pressure of at least 25 atmospheres is maintained and stage (b) is effected by stirring for 6 hours under a nitrogen atmosphere at 100 DEG C.  In Example 3 methane dithiol is obtained using a H2S:HCHO ratio of 10:1 and in Examples 1-4 a variety of polythiomethylenes are prepared using varying proportions of reactants in stage (a) and aqueous phases of differing pH in stage (b). In Example 5 the product from Example 1 is heated with distilled water, increasing the average molecular weight from 155 to 258.
