Patent GB-204078-A (GB)
Title: Improvements relating to the treatment of liquid hydrocarbons
IPC: C10G29/12
Filed: 1922-04-22
Abstract: Liquid hydrocarbons containing unsaturated bodies are purified by treatment in the liquid state with chlorine water or a solution in water of hypochlorous acid, and the product is treated with alkali to convert the chlorinated bodies into ethers and so produce a liquid suitable for use as a motor fuel.  The chlorinated bodies may be isolated by steam distillation, treated with alkali, and the ethers produced added to the hydrocarbon liquid.  Highly-cracked gasoline may be subjected to a preliminary treatment to polymerize the more active unsaturated hydrocarbons, e.g. it may be filtered through bauxite or other mineral adsorbent, or treated with mineral acid or with anhydrous chloride of aluminium or zinc.  In an example, a gasoline containing 0.3 per cent of sulphur is agitated with a solution of hypochlorous acid containing 35.5 gm. of chlorine per litre until absorption ceases.  The product is boiled gently with dry slaked lime until the chlorine is substantially eliminated, and is then distilled.

Abstract: 662,245. Code telegraphy. RADIO CORPORATION OF AMERICA. May 2, 1949 [May 20, 1948], No. 11668/49. Class 40 (iii). [Also in Group XL (c)] In a diversity receiver the strongest carrier corresponding to different versions of a received signal is selected in a carrier selector 18 and applied as exalted carrier to detectors 19, 19<SP>1</SP> of each signal version. The strongest detected signal may then be selected. The carrier and one or both side-bands of each version of a telegraph signal constituted by a frequency shifted tone amplitude or phase modulated on a carrier are separated in filters 12, 10 and each carrier applied to gate valves in a selector 18 comprising carrier strength comparing, detecting and gate locking circuits. The selected carrier is then limited and applied to converterdetectors 19, 19<SP>1</SP> to which the side-bands in each diversity channel are also applied. A carrier phase shifting network PS is switched in when phase-modulated signals are to be detected. Demodulated multiplexed tones from 19, 191 are then separated by filters 36, 38, 36<SP>1</SP>, 381, and each tone version applied to a signal strength selector circuit 40, 40<SP>1</SP> from which the strongest tone is derived and applied after limiting and filtering to remove gate switching components to a tone output line. Common A.G.C. may be used for the diversity channels, as shown. The gate circuits of the selectors 18, 40, 40<SP>1</SP> may be push-pull operated valves, Fig. 2 (not shown), opened or closed by cathode bias applied to them from cathode followers connected to the selector locking circuit. The converter-detectors 19, 19<SP>1</SP> comprise carrier suppressing pushpull valves to the grid circuits of which the sidebands and exalted carrier are applied in pushpull and in phase respectively. In a modification, Fig. 4 (not shown), the detected tones are frequency multiplied to obviate large time constants in the selector, then the selected output tone divided in frequency.
