Patent GB-742261-A (GB)
Title: Improvements in or relating to a method for insolubilising artificial filaments obtained by the spinning of solutions of proteins
Inventor: MCGILLIVRAY ROY
IPC: D01F4/00
Filed: 1952-12-31
Abstract: A bundle of protein filaments which has been treated with a hardening agent is insolubilized by impregnation with an acidified aqueous formaldehyde solution, drying at below 100 DEG C. and finally heating at 140-180 DEG C.  After impregnation, which is preferably effected by padding, the filaments are preferably stretched and dried in the stretched condition.  The bundle may also be dyed prior to impregnation.  In examples, the bundle of hardened filaments is obtained by extruding a peanut globulin solution into an aqueous sulphuric acid-sodium sulphate bath at 30 DEG C., the bundle of filaments then being stretched in a similar bath, relaxed in an aqueous sodium sulphate-sodium chloride bath of pH 8-9 at 25 DEG C. and finally hardened in an aqueous formaldehyde bath containing sodium sulphate and sodium chloride of pH 5 at 50 DEG C. Insolubilization of the hardened filaments is then effected by treatment with an aqueous formaldehyde solution acidified with hydrochloric acid to pH 2, with gluconic acid to pH 3 or with boric acid to pH 3-5, followed by drying at 80 DEG C., and heating at 160 DEG C.  In one example, the hardened filaments are washed and dried prior to impregnation and the impregnated filaments are stretched in air prior to drying.  In another example, the hardened filaments are dyed at 40 DEG C. with Solway Blue prior to impregnation. Specifications 513,910, 533,952, 597,497, 605,830, 623,460 and 642,359 are referred to.

[Also in Division F2] A pressure vessel, Fig. 1 (not shown), comprises a closed container (12) having reinforcing rings (20) and an inner surface (32) brazed to the complementarily contoured outer surface (108) of a helically coiled reinforcing tube (28) closed at one end (30) to provide a subsidiary chamber for fluid at a pressure higher than that stored in the container (12). In Fig. 5 (not shown) the tube (28) is circular in cross-section and nests in a helical groove (136) formed in the inner surface (32d) of the container (12). The contacting surfaces (118) of the coiled tube are brazed together and reinforcing wires (138, 140) are provided. The container has ends (16, 18) provided respectively with an outlet fitting (22) and an inlet valve assembly (40). The assembly (40) comprises a housing (42) containing a valve body (48) in which is disposed an inlet valve (62) and a slidable valve member (52). During filling pressure fluid is supplied through the inlet valve (62) and passes into a chamber (60) to flow therefrom through a passage (70) to the tube (28) and passages (80, 82, 84) in the member (52) to the container (12). The valve member (52) is subjected on its large end (75) to the pressure in the container (12), and on its small end (76) to the pressure in the tube (28) whereby the valve is displaced to the right to thereby always maintain a higher pressure in the tube (28) than in the container (12).

Title: Improved manufacture of esters including thio esters substituted in the acid residue
IPC: C07C69/22
Filed: 1932-11-25
Abstract: Esters, including thioesters, which are stated to have emulsifying properties are obtained by esterifying hydroxy or mercapto fatty acids which are alkylated, cycloalkylated, aralkylated or arylated at the oxygen or sulphur atoms with aliphatic compounds which contain either one or two hydroxyl or mercapto groups and at least eight carbon atoms, or with naphthenic or resin alcohols.  Instead of the acids, their functional derivatives may be used or derivatives such as those containing basic residues or halogen atoms or oxy, sulphonic or carboxy groups.  Similarly the aliphatic compounds may be replaced by their mineral acid esters, alcoholates or ester salts or substitution derivatives, e.g. ether derivatives.  In examples: (1) phenoxyacetic acid or chloride is used to esterify octanol, dodecanol, tetradecanol, hexadecanol, octodecanol, oleic alcohol, paraffin alcohols and the alcohols derived from coco nut fatty acids; (2) thiodiglycollic acid is esterified with octanol-1, dodecanol, and oleic alcohol; (3) the lactone of hydroxyethoxyacetic acid is esterified with octanol, dodecanol, octodecanol and coco nut alcohols; (4) phenoxyacetyl chloride is esterified in pyridine with dodecylmercaptan to obtain the dodecyl thioester.  The samples relate to the esterification of the following pairs of components: benzylmercaptoacetic acid and oleyl alcohol, cyclohexylacetic acid and oleyl alcohol, phenoxystearic acid and octanol and phenoxyacetic chloride and tri (12-oxystearic) glycerol ester.ALSO:Hydroxy or mercapto fatty acids which are alkylated, cycloalkylated, aralkylated or arylated at the oxygen or sulphur atoms are esterified with aliphatic compounds which contain either one or two hydroxyl or mercapto groups and at least eight carbon atoms, or with naphthenic or resin alcohols.
