Title: New heterocyclic compounds and their production
IPC: C07D285/13
Filed: 1955-10-13
Abstract: The invention comprises substituted 1,2,4-triazoline-5-thiones of the general formula <FORM:0776118/IV(b)/1> wherein R1 and R2 represent hydrogen atoms or methyl radicals, the triazoline-5-thiones may be in the tautomeric form indicated by the following general formul <FORM:0776118/IV(b)/2> and salts thereof derived from acids and bases, and the preparation thereof by heating an isonicotinic acid thiosemicarbazide of the general formula <FORM:0776118/IV(b)/3> wherein R1 and R2 have the above significance, or by reacting isonicotinic acid hydrazide with a thiocyanate to form an isonicotinic acid thiosemicarbazide of the above general formula which is then heated.  The heating step may be carried out in the absence of or in the presence of a high-boiling solvent such as tetrahydronaphthalene or cumene.  The ring closure may also be brought about by means of an alkaline condensing agent such as an alkali metal alcoholate in an alcohol.  Bases which may be used for salt formation with the thionones of the above general formula are alkalis such as sodium carbonate and bicarbonate, and organic bases such as isonicotinic acid hydrazide, p-aminosalicylic acid, ethanolamine and diethanolamine.  The isonicotinic acid thiosemicarbazide intermediate of the above general formula may also be isolated in the form of salts with acids or bases-suitable acids being hydrochloric, hydrobromic and thiocyanic acid.  In the examples, 3-g -pyridyl-D 2-1,2,4-triazoline-5-thione is prepared by heating isonicotinic acid thiosemicarbazide which is obtainable by heating isonicotinic acid and ammonium thiocyanate, and 3-(21-methyl-pyridyl-4)-D 2-1,2,4-triazoline-5-thione is prepared by heating 2-methyl-isonicotinic acid thiosemicarbazide.

Title: A method of manufacturing bronze colours
IPC: B22F9/04
Filed: 1930-09-30
Abstract: 360,142. Ball or tube mills for making bronze colours. HARTSTOFF-METALL AKT.-GES., 39, Kaiser Wilhelm Strasse, C÷penick, Berlin. Sept. 30, 1930, No. 29232. Convention date, Sept. 30, 1929. [Class 59.] Bronze colours in the form of relatively small foils are flattened in ball mills, a gaseous current being passed through the drum of the mill of such a strength that it removes the finished foils and also materially larger unfinished particles, the foils and particles being conveyed by the current to a sifter in which the foils are separated from the particles, the latter being conveyed back to the drum and re-lubricated before, during, or immediately after their re-introduction to the drum. The re-lubrication may be effected by adding the lubricant directly to the returning particles,. or by their contact, with the freshly supplied particles which are lubricated in excess of their normal requirements, or by adding the lubricant to the balls or particles at the inlet end of the drum. As shown, the metal particles are fed from a hopper 1 by a worm 2 and are lubricated by oilers 4, 6 on the way to the ball mill 12, the ends of which are conical and are provided with screens 13, 14 to retain the balls 15. A strong current of gas, e.g. nitrogen, carbonic acid, helium or combustion gases, is passed by the fan 16 through the passages 17, 30, 29, 10 into and through the mill, through the pipe 18 and into a separator 19 having stepped baffles 21 over the edges of which the material passes, the flattened grains being carried upward between the baffles to a cyclone separator 26 from which the foils are deposited in a receptacle 27 whilst the gas is returned by a pipe 28 to the fan 16. The unfinished grains are returned by a rotating blade-valve 31 to the mill, being re-lubricated in the pipe 29 by an oiler 8. The passages 36, 37 in the separator 19 are closable by flaps 32, 33 to regulate the effective sectional area of the sifter and consequently the fineness of the product, this being effected without altering the velocity of the gas through the drum. A filter or filters may be fitted in the return pipe 28. Relubricating oil may be added to the balls by the pipe 11. Specification 204,055, [Class 59, Grinding, crushing, &c.], is referred to.

Abstract: 1385428 Polyalkenamer-polybutadiene copolymers; vulcanizable rubber compositions CHEMISCHE WERKE HULS AG 22 June 1972 [24 June 1971] 29240/72 Headings C3P and C3Q Copolyalkenamers are prepared by reacting a rubbery butadiene polymer in which at least 80% of the butadiene units are in the 1,4- configuration with polyoctenamer and/or polydodecenamer in the presence of a catalyst comprising a compound of a transition metal of Group Va, VIa or VIIa and a non-transition metal of Group Ia, IIa, IIIb or IVb or a compound thereof, optionally with an activator. The process may be effected in the presence of a vinyl halide. The butadiene polymer may be a cis-1,4-polybutadiene or a butadiene/styrene copolymer. The process may be effected by adding the butadiene polymer to a polyalkenamer prepared with the above catalyst without deactivation of the catalyst, or by mixing preformed polymers and treating with the catalyst. Side reactions are suppressed by adding vinyl chloride or vinyl bromide before the butadiene polymer. The copolyalkenamers may be blended with vulcanizable elastomers to improve the thermoplasticity thereof. In Examples (1-5) cyclododecene is polymerized and cis-1,4-polybutadiene is added and (7) cyclododecene is polymerized in the presence of octene-1 and cis-1,4-polybutadiene is added, all in the presence of a catalyst comprising tungsten hexachloride, ethyl aluminium dichloride and ethanol; and the products are compounded with (8 and 9) natural rubber, SBR, cis-1,4-polybutadiene, carbon black, plasticizer oil, zinc oxide, stearic acid and vulcanizing ingredients.
