[Class 2 (iii)] Trialkyl-p-hydroxybenzenes are prepared by oxidizing a trialkylphenol containing a free p-position by means of a persulphate in alkaline solution, and' hydrolysing the resulting alkali salt of trialkylhydroquinone sulphate with a mineral acid. On further oxidation in acid solution, e.g. with ferric chloride, the corresponding p-quinones are obtained;. which may be reconverted into the hydroquinones by treatment with a reducing agent such as sodium hydrosulphite. The hydroquinones are useful as intermediates, in the preparation of tocopherols.. Examples are given of the oxidation of pseudo-cumenol-6 to pseudo-cumohydroquinone, and of 2-ethyl-3:5-xylene to 2-ethyl- 3:5-dimethylhydroquinone, using potassium or sodium persulphate in sodium hydroxide solution ; the oxidation of the products with ferric chloride to the corresponding quinones is also described.

Abstract: 594,774. Superheterodyne circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd.July 17, 1944. No. 13658. Convention date, Oct. 10, 1942. [Class 40 (v)] In a superheterodyne receiver, adapted to receive carrier having undesired frequency modulation, " local " oscillations are obtained by mixing the received carrier with a fixed frequency and passing the resulting frequency through an amplitude limiter to remove amplitude modulations. Amplitude modulated current obtained by mixing the received carrier with another fixed frequency, is mixed with the " local " oscillations to produce an I.F. independent of frequency variations of the received carrier. 20 Mc. from master oscillator 16, Fig. 1, is multiplied at 13, 14, 15 to produce 1600 Mc. which is combined with the 2000 Me. received carrier in mixer 18, to produce 400 Mc. local oscillations which are filtered at 19 and have their amplitude modulation removed by the limiter 20. 1500 Mc. obtained from multipliers 13, 12, 11, mixed at 2 with the received carrier produce amplitude modulated 500 Mc. which is filtered at 3 and mixed at 4 with the 400 Mc. " local " oscillations to produce 100 Mc. I.F. which beaten with 80 Mc. oscillations obtained from multiplier 17 produce a second I.F. of 20 Mc. which is filtered at 7 and rectified. at 8. In Fig. 2 (not shown), the 1500 Mc. and 1600 Mc. are obtained from the upper and lower side bands obtained by mixing fixed oscillations of 1550 Mc. and 50 Me. In Fig. 3 (not shown), the 1500 Mc. and 1600 Mc. are combined in the same mixer with the 2000 Mc. to produce an output containing both 400 Mc. and 500 Mc. which are then filtered and combined as above. In Fig. 4 (not shown), a 100 Me. oscillator is multiplied to produce 200 Mc., 400 Mc. and 1200 Mc.which latter mixed with the 2000 Mc. received carrier produces 800 Mc. which is mixed with both 200 Mc. and 100 Mc. in separate mixers to produce 700 Mc. and 600 Me., which latter is used as the local " oscillator and mixed with the 700 Mc.
