Abstract: 1312583 Gas chromatography; determination of gases given off by metal specimen BALZERS PATENT-UND BETEILIGUNGS AG 24 May 1971 [4 June 1970] 16692/71 Headings B1L and B1X [Also in Division G1] Apparatus for investigating a component of a gas mixture for example one obtained by heating a steel specimen under vacuum comprises a gas detector 6 and a sorption trap 4 for the selective and reversible fixing of the other components of the gas mixture, the sorption trap 4 having a support surface for a sorbent, a heatable zone and a coolable zone and being connected to an oscillatory device enabling selective positioning of the sorbent in the heatable or coolable zone of the trap 4. In use, a gas mixture to be investigated is supplied from a conduit 1 via a valve 2 and flexible line 3 to the sorption trap 4 where the sorbent is located in the cool zone for absorbing or adsorbing all but the component of interest which passes to a detector 6. After taking measurements, the supply of the gas mixture is cut-off and a vibrator 8 is actuated to transfer the sorbent from the cool zone of the trap to the hot zone where the sorbent releases those gas components previously fixed. The sorbent is then returned to the cool zone by a vibrator 9 ready for a further gas investigation. The hot zone may be heated by way of electric current and the cool zone may be water cooled. A carrier gas may be used during the investigations and during the regeneration of the sorbent the apparatus may be flushed with a further gas. In an alternative embodiment in which a carrier gas cannot be used and in which an aliquot part of the gas mixture to be investigated is fed to a sorption trap, a detector in the form of a manometer is arranged in the supply line of the gas mixture and the sorption trap comprises a pair of tubes (4a, 4b) (Fig. 2 not shown) which are heatable electrically adjacent their closed ends and coolable adjacent their open ends. The sorbent may comprise zeolite which is able to fix carbon monoxide and hydrogen in a gas mixture which also contains nitrogen and which is given off by a steel sample so that investigations on the nitrogen can be made.

Patent GB-439359-A (GB)
Title: Manufacture of carbocyanine dyestuffs
IPC: C09B23/06
Filed: 1934-06-05
Abstract: Thiocarbocyanine and selenocarbocyanine dyes substituted at the middle carbon atom of the trimethine chain are prepared by condensing a quaternary ammonium salt of a thiazole or selenazole having a reactive methyl group in a -position with an amide of a carboxylic acid having two or more carbon atoms unsubstituted or substituted at the nitrogen atom, preferably in the form of an acetal, in the presence of a condensing agent or solvent. Particularly suitable are the acetalized amides which are formed by fissure of oxazoles substituted in a -position to the nitrogen according to Specification 439,807.  By such means substituted amides of fatty, aromatic, heterocyclic and carbocyclic carboxylic acids can be obtained for use in the process.  In examples:  (1) 2-ethylbenzoxazole dimethylsulphate is treated with alcoholic sodium ethylate and the acetalized acid amide thus obtained condensed with 2-methylbenzthiazole ethiodide and 2-methylbenzselenazole ethiodide to give dyes containing a ms-ethyl substituent on the trimethine chain; (2) 2-propylbenzoxazole dimethylsulphate is heated with sodium ethylate and the acetalized butyric acid amide is condensed with the above ethiodides of (1) to give ms-propyl substituted dyes; (3) o-aminophenol is condensed with palmitic acid to give 2-pentadecylbenzoxazole which is converted to the dimethylsulphate salt and heated with sodium ethylate; the resulting acetalized amide is condensed with the ethiodides of (2) to give ms-pentadecyl substituted dyes; (4) Cyclohexylcarboxylic acid is condensed with o-aminophenol to give 2-cyclohexylbenzoxazole which is converted in the form of its dimethylsulphate salt to an acetalized amide by the action of sodium ethylate; this amide is condensed with the ethiodides of (1) to give ms-cyclohexyl substituted dyes; (5) pyromucic acid is condensed with o-aminophenol and the resulting furylbenzoxazole in the form of the dimethylsulphate salt is converted to an acetalized amide by the action of sodium ethylate; condensation of this amide with the ethiodides of (1) yields dyes containing a ms-furyl substituent.  Samples have been furnished under Sect. 2 (5) of dyes prepared (a) by reaching 2-phenylbenzoxazole dimethylsulphate with alcoholic sodium methylate and the resulting acetalized amide with 2-methylbenzselenazole ethiodide; (b) by reacting N-oxyphenylmethylacetamide with 2-methylbenzthiazole ethiodide in presence of sodium methylate. The dyes containing a higher alkyl substituent in ms-position on the trimethine chain are characterized by high solubility in alcohol and increased solubility in organic diluents.  The Specification as open to inspection under Sect. 91 relates to the condensation of quaternary ammonium salts of heterocyclic nitrogen bases having reactive groups in a -position with unsubstituted or substituted acid amides to give polymethine dyes substituted at the middle carbon atom of the polymethine chain. This subject-matter does not appear in the Specification as accepted.
