Patent GB-285017-A (GB)
Abstract: 285,017. Selden Co., (Assignees of Jaeger, A. 0.). Feb. 8, 1927, [Convention date]. Phthalic anhydride obtained by the vapour phase oxidation of naphthalene by air or oxygencontaining gases in presence of catalysts is purified by subjecting it to conditions favouring the condensation and polymerization of unsaturated components whereby substances of much higher boiling point than phthalic anhydride are formed from the impurities and then distilling or subliming. Methods specified are :-(1) Heating at atmospheric, reduced, or raised pressure, preferably with continuous agitation and at about the boiling point of the anhydride; at very high pressure distillation alone may be sufficient. (2) Boiling and condensing the vapours in a condenser having a relatively large condensation surface: preferably a reflux condenser containing a large number of tubes 1-1.5 metres high is used. The large surface may be obtained by packing the condenser with fragments of quartz, pumice. metals or aliovs, coke, silica gel, activated carbon, kieselguhr, diatomaceous stones, unglazed porcelain, or zeolites. (3). Contacting the vapours, preferably in a reflux condenser, with fragments of condensation or polymerization catalysts having little effect on the anhydride, e.g. aluminium oxide, chromium salts, oxides of manganese, zinc oxide, or ferric oxide, alone or mixed. (4). Introducing gaseous condensation catalysts or finely divided liquid or solid condensation catalysts into hot molten anhydride; catalysts specified are superheated steam, concentrated sulphuric acid, aluminium chloride, zinc chloride, aluminium oxide, and manganese dioxide. In an example phthalic anhydride obtained by oxidizing naphthalene vapour by air at 370-420‹ C. in presence of vanadium cata'ysts, is heated gradually and uniformly to 284.5‹ C. and maintained boiling under a reflux condenser for about 6 hours. It is then fractioned the anhydride being condensed on cooling drums or by blowing air or indifferent gases into the liquid or vaporous anhydride. If a pressure of 1-3 atmospheres is maintained during the heating a lower temperature maintained for 4 hours is sufficient. Other examples are given. The Specification as open to inspection under Sect. 91 (3) (a) states that the impurities may be removed by halogenizing with or without halogen carriers. e.g. chlorine may be passed into molten phthalic anhydride, in the presence of manganese dioxide, which acts as a chlorine carrier, and neutralizes any hydrochloric acid formed, or the impurities may be oxidized, e.g. by ozonized air or sulphur trioxide. This subject-matter does not appear in the Specification as accepted.

Filed: 1961-08-11
Abstract: 969, 917. Measuring temperature electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 19, 1962 [Aug. 11, 1961], No. 29158/61. Heading G1N. A temperature measuring device, particularly for nuclear reactor fuel elements, comprises a probe with a magnetic core, electrically heated to its Curie point and an integrator to measure the additional energy required by the probe to reach this temperature. The probe 11 (Fig. 1) comprises two coaxial conductors shorted at one end, the inner conductor adjacent the short circuit being of comparatively high resistance, coated with a material of high magnetic permability, and in thermal contact with a fuel element. An A.C. supply to the probe has a constant current characteristic due to a series high resistance 12. As the probe temperature rises, its permeability falls causing a reduction in the voltage across it, this voltage remaining substantially constant when the Curie point is reached. The initially changing voltage is differentiated at 15, (Fig. 2) and amplified at 16 to energize a relay coil 13. When the Curie point of the probe is reached, the differentiator output is zero and relay 13 is de-energized, whereupon the probe heating current is interrupted at 13a. Signals proportional to the probe resistance and to the square of probe current respectively from devices 17, 18, are multiplied at 19 and integrated at 21. A normally closed contact 13b is open when probe heating takes place and the integrator output is combined in a unit 22 with signals dependent upon auxilliary probe parameters such as self heating, to obtain a corrected integral and hence element temperature. The probe may alternatively comprise a resistor with two temperature dependent solid phases, and the apperatus is sensitive to the constant temperature at which the material changes from the one state to the other. A number of probes may be connected in series to the integrating circuit which thus determines the temperature at the hottest probe.
