Title: Improvements in or relating to phenthiazine derivatives
Inventor: JACOB ROBERT MICHEL
IPC: A61K31/00
Filed: 1954-06-21
Abstract: A process for the preparation of compounds of the formula: <FORM:0774882/IV(b)/1> and their salts including quaternary ammonium compounds wherein the -CH2- bridge is directly connected to a ring carbon atom of the piperidine nucleus, preferably in the 3- or 4-position, at least one of the benzene rings of the phenthiazine nucleus may contain a halogen, alkyl, alkoxy, phenyl or phenoxy substituent group, preferably in the 3-position and R represents a hydrogen atom or an alkyl group containing not more than 4 carbon atoms or a benzyl group, comprises reducing a phenthiazine compound of the general formula: <FORM:0774882/IV(b)/2> (wherein Hal represents a halogen atom and the phenthiazine nucleus may be substituted as aforesaid) by the application of known methods for the reduction of pyridine derivatives to the corresponding piperidine derivatives.  The reduction may be effected catalytically, suitably with an Adams platinum catalyst in absolute ethanol (at ordinary or increased temperature and pressure) or in aqueous alcohol (at increased temperature and pressure).  Substituents on the piperidine nitrogen atom may be present in the starting material or be introduced by alkylation processes.  In Example (1): 1-methyl-3-(101-phenthiazinylmethyl)-pyridinium iodide is hydrogenated in absolute ethanol in presence of Adams platinum catalyst to give 1-methyl-3-(101-phenthiazinylmethyl)-piperidine hydriodide from which the free base, hydrochloride and picrate are prepared. Similarly obtained are 3-methyl - 10 - (1 - methyl - 3 - piperidyl) - methylphenthiazine; (3) 3 - chloro - 10 - (1 - methyl-3 - piperidyl) methylphenthiazine; (4) 3-methoxy - 10 - (1 - methyl - 3 - piperidyl) methylphenthiazine; (5) 10 - (1 - benzyl - 3 - piperidyl) methylphenthiazine; (6) 3 - chloro-10 - (1 - methyl - 4 - piperidyl) - methylphenthiazine; (7) 10 - (1 - methyl - 4 - piperidyl) methylphenthiazine.  In Example (8): 10-(31-pyrdylmethyl)-phenthiazine hydrochloride is hydrogenated in an autoclave at 60-90 kg/cm.2 pressure and 60 DEG  C. to give 10-(31-piperidylmethyl)-phenthiazine which is recovered as the methanesulphonate.  Starting materials of the second formula above are obtained by the action of a halogenomethylpyridine, preferably in the presence of a condensing agent, on the appropriate phenthiazine and reaction of the product with a compound R Hal.  In this manner are prepared 10 - (31 - pyridylmethyl) - phenthiazine and corresponding compounds having 3-methyl, chloro and methoxy substituents, 3-chloro-10-41 - pyridylmethyl) - phenthiazine and 10-(41-pyridylmethyl) - phenthiazine and quaternary compounds of these bases, for use in the above examples. Specification 774,883 is referred to.

Title: Improvements in or relating to processes of and apparatus for melting melt-spinnablesubstances
IPC: D01D1/04
Filed: 1952-07-23
Abstract: <PICT:0728233/IV (a)/1> Solid particles of a melt-spinnable substance such as a polyamide are continuously fed to a melting space, within which they are retained until completely melted; a stream of the same substance in the molten state is caused to flow between and over the solid particles retained in the melting space so that they are gradually melted; and the stream of molten substance is collected, together with the freshly molten substance so obtained, in a collecting space from which the stream of molten substance required for melting the solid particles is continously withdrawn.  As shown, solid polymeric melt-spinnable substance in chips, granules or other comminuted form is fed into the melting apparatus from a feed reservoir or measuring device and falls into a basket 14. The polymer may be preheated before entering the melting apparatus.  Molten polymer 11 is collected in the lower part of the melting chamber.  A circulation pump 16 draws liquid polymer from the bottom of the chamber and forces it through conduit 17 and tube 18, from the end of which the liquid flows on to the mass of solid particles held in the basket 14.  The liquid is maintained at a temperature above the melting point of the polymer, e.g. 20 DEG  C. above, so that it melts the solid particles as it passes in contact with them.  The liquid polymer, including that portion obtained from the freshly melted particles, passes through the walls of the basket into the lower part of the melting chamber.  The whole melting chamber may be surrounded by a jacket 20 through which heating fluid may be circulated, and the temperature may be thermostatically controlled.  The conduit 17 may be surrounded by an electric heater 21.  The molten polymer is delivered to a spinneret by way of conduit 23.  At the beginning of the operation, the collecting space or sump is filled with molten polymer, either by introducing polymer that has been melted in some other apparatus or by introducing solid polymer through an opening, normally closed by lid 24, and melting it by specially provided heating devices or by the heating devices used for maintaining the temperature of the melting chamber at a desired value during normal operation.  Specification 728,232 is referred to.

Abstract: 1,102,576. Filaments. COURTAULDS Ltd. 5 May, 1965 [6 May, 1964], No. 18756/64. Heading B5B. Filaments of a copolymer containing at least 25 mole per cent vinylidene chloride are wetspun by extruding an acetone solution of the copolymer into a coagulating bath, decreasing the acetone content of the filaments to 4% wt., and then heating the filaments by contacting with steam and simultaneously stretching them. The decrease in acetone content may be achieved by extensive washing e.g. by soaking in water for several days, or by prolonged storage of the filaments. In examples an acetone solution containing 30% wt. solution of a 50/50 acrylonitrile/vinylidene chloride copolymer is extruded and coagulated in water which may contain 5% wt. acetone; the filaments are then stretched by 100%, washed with water, and then treated to reduce acetone content. They are then stretched 10 x in steam at 30 or 40 p.s.i. and dried. The density of the filaments is about 0À7 g/c.c.
