Title: Improvements in or relating to processes of producing a dicarboxylic acid derivativeof a sulphathiazole
IPC: C07D277/52
Filed: 1945-08-30
Abstract: 2 - (N4 - Carboxyacylamino - benzenesulphon - amido) thiazoles are prepared by reacting maleic or succinic or phthalic anhydride with sulphathiazole, or 4-alkyl-sulphathiazole or 2-sulphanilamido-4-5-6-7-tetrahydrobenzothiazole in the presence of a ketone or a mixture of ketones as a solvent.  It is preferred that the reaction should take place at a temperature below 60 DEG  C., and also that the ketone acid is one which is liquid at 30 DEG  C. Ketones mentioned as suitable include acetone, methyl ethyl ketone, methyl propyl ketone, methyl isopropyl ketone, other isomeric pentanones, and the isomeric hexanones and heptanones. Before isolating the reaction product it is preferred to add a small amount of water.  In the case of the succinyl derivative, this results in the product being obtained in the form of the monohydrate.  In examples: (1) equimolecular amounts of sulphathiazole and succinic anhydride are refluxed in acetone, after which water is added and the acetone distilled off.  The product is N4-succinyl-sulphathiazole monohydrate; (2) as in example (1) but omitting the addition of water; (3) equimolecular amounts of sulphathiazole and phthalic anhydride are refluxed and water added as in example (1) to form anhydrous N4-phthalylsulphathiazole.  This is purified with charcoal in aqueous alkaline solution.

Filed: 1925-09-16
Abstract: 262,858. Beardmore & Co., Ltd., W., and Webster, T. H. Sept. 16, 1925. Loading-appliances.-A ramming device comprises two rammers, one for the projectile and one for the charge, which are moved forward simultaneously during the ramming operation but are retracted successively, the charge rammer being held in the forward position by the ramming device until the projectile rammer has been retracted, and being then retracted in its turn by the rammer-actuating means. As shown, the main or projectile rammer 8 is a hollow cylinder carried by a telescopic ram 3, 3<1> moving in a cylinder 1. The secondary or charge rammer 9 is situated within the projectile rammer 8 and is attached to a telescopic ram 6, 6<1> moving within a cylinder 4. The cylinders 1, 4 are carried together by a block 12 pivoted on a bracket 13. This ramming device is swung out to receive the charge 14 and is then swung back into line with the gun barrel and with the projectile 16 in a pivotal loading tray 17. A valve 18 is set to admit compressed fluid behind the pistons 3, 3<1> and ram the charge and projectile home, the charge rammer 9 being carried forward by the projectile rammer 8, and compressed fluid entering behind the rams 6, 6<1> by a non- return valve 19. The valve 18 is then set to exhaust the cylinder 1 and retract the rams 3, 3<1> and projectile rammer 8; meanwhile, the charge rammer 9 and the rams 6, 6<1> are held in their forward position by the pressure fluid trapped behind the rams 6, 6<1> until a projection 21 on the projectile rammer 8 strikes a tappet 22 and sets a valve 20 to exhaust the cylinder 4 and retract the rams 6, 6<1> with the charge rammer 9. The pressure fluid devices may be replaced by a spring motor device associated with a detent and ratchet for controlling the retraction of the charge rammer.

In the hot extrusion of composite metal billets composed of at least two thicknesses of different metals 29, 30, a layer of glass-like lubricating material 31, 33 which remains viscous during extrusion, is provided respectively between the billet and the container 22 and between the billet and the extrusion die 24. The layer 31 is preferably formed by wrapping a sheet of glass fibre around the billet after the latter has been heated in a non-oxidizing furnace, or preferably in a molten salt bath such as of barium chloride or barium chloride and sodium chloride. The end piece 33 may cornprise one or more glass plates, glass wool or cellular glass. Certain oxides and salts, such as boron trioxide, phosphorus pentoxide or sodium metaphosphate, or certain natural or synthetic slags may be used instead of glass. The billet comprises an inner cylinder 30 of mild steel and an outer cylinder 30 of 18-8 type stainless steel, the two cylinders being welded together at 34. In the extrusion of a composite tube, a layer of lubricating material 32 is also provided between the billet and the mandrel 27. The latter is mounted in a support 28 which is slidable within the ram 25. In another embodiment a bar is extruded from a composite billet composed of three different metals. Billets with cylindrical and conical inner portions are described together with the extruded bars produced therefrom. Comparison is made between the use of grease and graphite and the glass-like lubricants for extruding various forms of billet. A specific example is given of the billet dimensions and pressure used in the extrusion of a composite tube. Specifications 607,285, 661,555, 663,357 and 684,013 are referred to.
