Title: Method and apparatus for heating flowing gases or vapours
IPC: F28D7/00
Filed: 1944-02-12
Abstract: 630,184. Gas &c. heating furnaces. INDUSTRIKEMISKA AKTIEBOLAGET, and NAUCLER, J. O. Feb. 12, 1944, No. 2640. Convention date, Nov. 28, 1941. [Class 64(i)] In a gas or vapour heater in which the gas or vapour to be heated flows througt tubes, preferably vertical, arranged in a chamber through which a heating gas flows, the tubes are so distributed and the stream of heating gas is so restricted that the stream does not flow directly on the tubes but heats them substantially only by radiation from or through a gas depth (i.e., the distance between the tube wall and the remotest point of the radiation heat source) of 0.5 metre or more, preferably one metre or more. Every part of the tubes heated by radiation from the gas stream receives heat from all parts of the stream. In the form shown, gas to be heated flows downwardly through a ring of tubes 6 suspended from an annular header 10, and is heated by combustion gases flowing from a gas burner 2 to an outlet 9. The tubes are spaced so that the wall 7 of the chamber 20 is heated, and also heats the tubes, ,by radiation. The top of the furnace has a projection 17 which screens the junction of the tubes 6 and header 10 from direct radiation from the burner. The wall 7 may comprise an inner layer of refractory bricks surrounded by a layer of chamotte grains, a layer of stone wool, and an iron casing. It may have a low heat capacity, e.g., be made of a material of low specific heat, to cool rapidly if the heated and heating gases are cut off. The combustion gases discharged from the heater may be used to preheat the air or gas for combustion or the gas or vapour to be heated. The Specification as open to inspection under Sect. 91 describes an expansion device between the lower header 11 and gas outlet 15, comprising a pipe with its lower edge submerged in a liquid seal composed of molten lead, lead alloy, Babbit metal, &c.. located in an annular pocket. This subject-matter does not appear in the Specification as accepted.

Patent GB-814339-A (GB)
Title: Dextro-rotatory n-ethyl-alpha- methylphenethylamine and acid addition salts thereof
Filed: 1957-01-29
Abstract: The invention comprises dextro-rotatory N-ethyl-a -methylphenethylamine and its acid addition salts, a process for its manufacture by forming a solution of the diastercoisomeric salts of racemic N - ethyl - a  - methylphenethylamine and an optically active N-benzoylthreonine in a solvent comprising a water-soluble lower alkanol and/or water, separating the diastereoisomeric salts by fractional crystallization and recovering the dextro - rotatory - N - ethyl - a  - methylphenethylamine from the optically active N-benzoylthreonine salt thereof, and pharmaceutical compounds containing the product (see Group VI).  In an example, equimolecular amounts of N-benzoyl-D-threonine and racemic N - ethyl - a  - methylphenethylamine are dissolved in water and the (-)-N-ethyl-a -methylphenethylamine - N - benzoyl - D - threonine salt allowed to crystallize.  The base is liberated and converted into its hydrochloride.  The resolution liquors are made alkaline, the (+)-amine is recovered as the free base and converted into its hydrochloride; alternatively the crude (+)-amine is converted into its N-benzoyl-L-threonine salt, purified, liberated as the free base and subsequently converted into the hydrochloride.  In a further example N-benzoyl - L - threonine is employed to yield the (+) - N - ethyl - a  - methylphenethylamine - N - benzoyl - L - threonine salt on the first crystallization, the free (+)-amine base is liberated and converted into its hydrochloride.  The resolution liquors are made alkaline and the (-)-amine base extracted with ether and converted into its hydrochloride.  Acidification of the liquors in both examples after the removal of the amine bases yields N-benzoyl-D or L-threonine according to previous treatment.  The free base may be converted, if desired, to an acid addition salt by treatment with an organic or inorganic acid.ALSO:The invention includes an analgesic composition comprising a major weight proportion of an analgesic drug and a minor proportion of dextro - rotatory N - ethyl - alpha - methylphenethylamine in crystalline and substantially pure form and substantially free from its laevorotatory optical antipode, or an acid addition salt thereof (see Group IV (b)).  Analgesic drugs include acetylsalicylic acid, meperidine acetophenetidine, acetanilide, p-acetylaminophenol, codeine phosphate, mephabarbital and talbutal, the preparations being in the form of tablets, powders, wafers and elixirs.  Examples are given of tablets containing, in addition to the analgesic drug, caffeine or theophylline.  Tablets are also described containing dextrorotatory N-ethyl-alpha-methylphenethylamine hydrochloride as the only medicament, preparations containing the medicament together with B-vitamins or with reserpine, a syrup with sodium L-glutamate, vitamins and minerals, and a nasal decongestant containing menthol.
