Title: Improvements in and relating to the purification of hydrocarbons
IPC: C07C7/148
Filed: 1933-10-14
Abstract: Benzol, which may have been treated with 77 per cent sulphuric acid, water, and aqueous alkali, is freed from carbon disulphide and other sulphur compounds by vigorously agitating with a mixture of methyl alcohol and at least 1,5 lb. of solid caustic alkali per gallon of alcohol, separating the agent, and washing with water.  2--5 per cent of methyl alcohol is suitable.  Methyl alcohol and carbon disulphide or alkali methyl xanthate are recovered from the used agent by: (a) adding carbon disulphide to react with all remaining alkali and distilling under reduced pressure whereby methanol distils over and xanthate remains as a pale yellow hydroscopic solid; or (b) diluting with water before or after separation of the benzol, separating the benzol, acidifying e.g. with sulphur dioxide or 20--30 per cent sulphuric acid, and separating the disulphide e.g. by collecting the first fractions under water collecting, as described in Specification 416,404; or (c) diluting with 0,5-1,0 vol. of water after separation of the benzol, distilling, and fractioning the mixture obtained.  The disulphide may be refined by washing with 5--10 per cent caustic soda, water, 77--95 per cent sulphuric acid, water, and dilute alkali or soda ash, and fractionally distilling.  In an example, 20 gallons of anhydrous methanol, 50 lb. of flake caustic soda, and 2500 gallons of benzol are agitated together for 3 hrs. In a second example the methanol contained 10 per cent of water.  Specifications 15777/12, [Class 1 (ii)], and 335,952, [Class 91], also are referred to.

Abstract: 865,467. Amplifier characteristics measuring. BUSH & RANK CINTEL Ltd. March 9, 1959 [March 7, 1958], No. 7388/58. Class 37. The input-output transfer characteristic of an amplifier 3 is tested by applying an exponentially time varying voltage cyclically to the input of the amplifier 3 the output voltage of which is applied to the input of a logarithmic amplifier 5 so that deflection plates 9 of a cathode-ray oscilloscope 10 deflect the electron beam according to the logarithm of the output of amplifier 3, whilst deflection plates 11 deflect the beam according to a linear time-base generated by circuit 12 in synchronism with the exponential voltage. Generator 1 which produces the cyclic exponential voltage, and circuit 12 are controlled by signals applied to terminal 2. A linear amplifier 8 may be included between amplifier 5 and oscilloscope 10. In operation, switch 4 is set to select the output of generator 1 and switch 6 is set to connect amplifier 5 directly to amplifier 8. The oscilloscope trace should then be a straight line, preferably sloping at 45 degrees. The output of amplifier 3 is then selected by switch 4, the oscilloscope displaying the transfer characteristic plotted in logarithmic co-ordinates. Assuming the cyclic voltage x = e<SP>-kt</SP>, where k is a constant, and amplifier 3 has an output y = x<SP>γ</SP>, that is y =e<SP>-γkt</SP>, the slope of the above display at any point is y. By including a differentiating circuit 7 between amplifiers 5 and 8, a plot of y versus the logarithm of the input voltage is obtained. Specifications 843,828 and 865,466 are referred to.
