Patent GB-445805-A (GB)
Title: Improvements in the manufacture and production of organic sulphur compounds
Filed: 1935-02-08
Abstract: Aminoethanethiols and aminoalkylethanethiols are manufactured by causing an alkylene 1 : 2-sulphide to act on a primary or secondary monovalent or polyvalent amine (aliphatic, cycloaliphatic, aliphatic-aromatic, aromatic or heterocyclic) or a secondary heterocyclic base, below about 300 DEG  C.  The reaction may be performed by heating the mixture of reacting materials, if desired in the presence of solvents inert to the alkylene sulphides, e.g. benzine or benzene hydrocarbons or ethers, or by heating the amine, if desired dissolved or suspended in a suitable solvent, and then introducing the vaporous or liquid alkylene sulphide at the rate at which it is absorbed.  In order to reduce the polymerizing action of the amines on the alkylene sulphides it is advantageous to reduce their basic action by the addition of suitable substances, e.g. phenols.  The products are suitable for the preparation of dyestuffs, vulcanization accelerators, or auxiliary agents or assistants for the textile industry.  In examples: (1) aniline and ethylene sulphide are heated under pressure to produce anilidomonoethanethiol; similarly o-toluidine yields o-toluidinomonoethanethiol, b -naphthylamine yields 2-naphthylaminomonoethanethiol and n-dodecylamine yields n-dodecylaminomonoethanethiol; (2) aniline and 1 : 2-propylene sulphide similarly yield anilidomonopropanethiol, whilst benzylamine yields benzylaminomonopropanethiol, n - butylamine yields a mixture of n-butylaminomono- and -dipropanethiols, and cyclohexylamine yields a mixture of cyclohexylaminomono- and -dipropanethiols; (3) piperidine and ethylene sulphide are heated under pressure, producing piperidinomonoethanethiol and piperidinoethanethioethanethiol; (4) propylene sulphide vapour is led into aniline to produce anilidomono- and -polypropanethiols; (5) monomethylaniline and ethylene sulphide are heated under pressure, yielding N-methylanilidomonoethanethiol; N-methyldodecylamine similarly yields N-methyldodecylaminoethanethiol; (6) aniline and ethylene sulphide are heated under pressure to produce anilidomono- and -diethanethiols; for the preparation of the diethanethiol, the monoethanethiol may be used as starting material; dibutylamine similarly yields dibutylaminomonoethanethiol and dibutylaminoethanethioethanethiol.

Title: Filamentary material
IPC: D01F11/12
Filed: 1971-02-09
Abstract: 1379547 Carbon fibres COURTAULDS Ltd 30 March 1972 [9 Feb 1971] 4221/71 Heading C1A The tensile strength of carbon filaments is increased by exposing the filaments to treatment by a gaseous halogen in the presence of water vapour. The preferred halogens are chlorine and bromine. Preferably the treatment is carried out at elevated temperatures. The halogen treatment may be followed by heat treatment in an inert atmosphere, e.g. nitrogen. The carbon filaments thus treated may be embedded in a resin matrix, e.g. an epoxy resin or a polyester resin.

Filed: 1972-02-02
Abstract: 1417550 Epoxides IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Feb 1973 [2 Feb 1972] 4835/72 Heading C2C Epoxides are prepared by passing an olefinic compound in the vapour phase together with oxygen and at a temperature below 300‹ C. over a solid substance comprising a copper compound capable of being oxidized by the oxygen and has a surface area of at least 5 square metres/gram and separating an epoxide derivative of the olefinic compound from the vapour products formed by resultant oxidation of the olefinic compound in the presence of the copper compound. The preferred starting olefines include ethylene, cyclohexene and butenes and, particularly, propylene. The copper compound may be supported, e.g. on alumina, silica, alumina-silica, titania, aluminium phosphate, zinc oxide, zirconia, silicon carbide, magnesium phosphate, calcium phosphate or titanium phosphate. The copper catalyst is preferably prepared by spray-drying a solution of a precursor copper compound, e.g. an aqueous solution of a cupric salt, especially a salt of an inorganic oxy acid, followed by controlled reduction of the solid material so obtained. An example describes the oxidation of propylene to propylene oxide using a catalyst obtained by dissolving cuprous oxide and ammonium molybdate in the presence of air in water containing ammonia, spraydrying the resulting solution and calcining the resulting fine powder.

The backing web and polymeric material are such that the backing web adheres to the polymeric material when hot but not when cold and web is preferably polyethylene terephthalate or polyvinyl chloride when the polymeric material is polyethylene and is also polyethylene when the polymeric material is polyvinyl chloride. Other polymers which may be used include polystyrenes and polyamides.

[Also in Division B2] A fluid control valve comprises a perforated plate 31 disposed in a passageway connecting an inlet 10 and outlet 9 of a valve body, and a resiliently deformable valve member 29 bearing on the plate and adapted to allow fluid to pass to the outlet when the member is deformed away from the plate by the inlet pressure so as to close vent ports 18 which communicate with the outlet. The vent ports are further closed by a teat-shaped valve portion 34 formed round a central aperture 32 of the valve member, this portion having slits 36 and seating on the outlet 9 in the deformed position. The device may be incorporated in a paint or chemical spraying apparatus, Fig. 1, wherein the body part 1 forms a hose connection which is rotatably mounted on the outlet 9 through a ring 44 which carries the ports 18. The hose end bears against a resilient sealing washer 11. Fluid is delivered through the device to a manually rotatable plug valve 7 and thence to a spray nozzle 4, the paint or chemical being thereby drawn through a connection 5 from a container which is closed by a cover 2. This cover carries the parts above described. A number of minor modifications of the valve device are disclosed.

Abstract: 725,700. Separating liquid particles from air and other gases; steam traps. NORGREN CO., C. A. Feb. 25, 1953 [July 17, 1952], No. 5294/53. Classes 64 (2) and 123 (3). [Also in Groups II and XXIX] A device for separating dirt and entrained liquid from a stream of compressed gas, especially compressed air, consists of a cylindrical body 12 into which the contaminated gas flows through an inlet 14, the gas passing through a filter 31, which removes solid matter, into an annular space 33, whence it flows downwardly through a perforated plate 32 and is guided by vanes 36 attached to the plate below each hole therein in a circular path along the wall of a vortex chamber 34 wherein the entrained liquid is separated by centrifugal force. The clean gas passes to the outlet 16 through a passage 22 in a baffle member 17. The separated liquid drains from chamber 34 through holes 44 into a reservoir 46 mounted below the body 12 and is discharged automatically therefrom when it reaches a preset level through a drain valve 67. The drain valve is actuated by a diaphragm 68 mounted in a valve housing 47, the movement of the diaphragm being controlled by a float 92 carrying a valve 89 which, when the float is in the normal or non-floating position, closes the upper end of an axial tube 83. When the float is lifted bv the liquid, compressed gas enters the tube through openings 91 and flows through passage 93 into a chamber 95, the gas pressure lifting the diaphragm and with it the discharge valve 67 against the pressure of a spring 74. After the liquid has discharged through the valve, the tube 83 is closed by the descending float and the spring returns the diaphragm to its normal position, the gas in chamber 95 bleeding off through a passage 97.
