Title: Heat treatment for hardened steel
Filed: 1929-05-27
Abstract: 314,056. Vereinigte Stahlwerke Akt.- Ges. June 22, 1928, [Convention date]. Drawings to Specification. Modifying physical characters of metals.-In a process for rendering hardened steel shape-retaining under extreme temperature changes the steel is first cooled to a temperature below 0‹ and then reheated to the lowest possible temperature above that at which the first shortening due to internal changes would occur if the steel were progressively heated to a high temperature, the reheating temperature being maintained for a period sufficient to effect the suppression of the shortening and being selected with regard to the hardness desired; carbon steel being reheated to about 100-150‹ C. for a period ranging from 6-8 hours to 1 hour. In another example, a steel containing 1 per cent of carbon and 1 per cent of chromium was cooled in liquid air and then aged for 100 hours in boiling water. In order to test the suitability of the treatment according to the invention when applied to a given steel two samples of the heated steel are respectively cooled to a very low temperature, as by immersion in liquid air, and heated to a temperature of 200-300‹ C. for a period of 10-20 minutes, and the variations in dimensions in both cases ascertained after the room temperature has been regained. The correct treatment for a given steel is that after which the variation and dimensions is practically zero.

Patent GB-810552-A (GB)
Title: The treatment of aqueous solutions containing alkali-metal salts of terephthalic acid
IPC: C07C51/41
Filed: 1956-05-29
Abstract: Mono-alkali-metal terephthalate is precitated from an aqueous solution of di-alkali-metal terephthalate at a temperature not above 50 DEG  C. by passing in carbon dioxide.  The corresponding alkali-metal bicarbonate is also formed.  The mono-alkali-metal terephthalate obtained may then be disproportionated to give terephthalic acid and di-alkali-metal terephthalate by treatment with water at elevated temperature.  The term "alkali-metal" includes ammonium.  Alkali-metals specified are sodium, potassium, and ammonium.  The di-alkali-metal terephthalate used may be that obtained by heating alkali-metal salts of o-phthalic or benzoic acids, by the alkali washing of terephthalic acid-containing oxidation products, or from the alkaline hydrolysis of wastes from synthetic or plastic material containing terephthalic acid.  The di-alkali-metal salt solution which may contain undissolved di-alkali-metal terephthalate may be treated with carbon dioxide at ordinary or elevated pressure. The precipitation may be conducted fractionally for the purposes of purification.  After removal of the mono-alkali-metal salt precipitate, the filtrate may be successively concentrated and treated with carbon dioxide to obtain further product. Disproportionation of the mono-alkali-metal salt may be effected by boiling it with water or by heating it with water under elevated pressure and separating the precipitated terephthalic acid. Examples illustrate the conversion of di-potassium, di-sodium and di-ammonium terephthalates to the corresponding acid terephthalates, and the hydrolysis of mono-potassium terephthalate to terephthalic acid and di-potassium terephthalate.
