Title: Independent electron gun bias control
IPC: H04N9/72
Filed: 1974-02-12
Abstract: 1456439 Cathode-ray tube circuits RCA CORPORATION 12 Feb 1974 [15 Feb 1973] 6315/74 Heading H4T The invention is concerned with independently controlling the bias applied to each of the cathodes of a plural gun colour television cathode-ray tube and is particularly concerned with tubes of the " in-line " gun type which have only a single first control grid and a single screen grid for all of the (three) guns. A " service adjustment " for such a three-gun colour television receiver involves the steps of arresting the vertical deflection system, disabling the luminance signal channel and adjusting the bias on the guns to produce a " dim "  white horizontal line. Referring to the drawing, to effect the " setup " procedure, a switch 30 is operated to the " service " position resulting in; the cut-off of the I.F. amplifier stages by the action of the AGC circuit 12 when " earth " is removed from contact 1; the interruption of the luminance output of transistor amplifier 29 by opening contact 4; the disablement of the vertical deflection by the application of " earth " to contact 3 and the supply of a reference voltage H + via contact 6, from a source 31, to input 48 of the Red drive module 46 (and to the Green and Blue drive modules 66, 67, the operation of which is identical to that of the module 46). In this condition the outputs of the colour demodulator 19 which are supplied to the modules 46, 66, 67 are all at their quiescent levels which correspond to a black level signal (or any grey scale signal) and the cathode 74 (and similarly for the guns 75, 76) is clamped to the voltage at collector of transistor 45 by the action of capacitor 37 and diode 35 on the cathode bias derived from a potentiometer 56. The latter, together with potentiometers 57, 58 for the drive modules 66 and 67, respectively, form a bias control circuit 52 supplied with horizontal flyback pulses + H (400 V peak-to-peak) from the video, synch and deflection circuit 15, a resistor 81, connecting the circuit to a + 200 V supply vi a clamp diode 54. The "set-up " procedure consists in; setting the screen voltage control 70 at minimum voltage, setting the drive controls 60, 62, 64 at maximum and cutting each gun completely off by setting potentiometers 56, 57, 58 to their maximum positive voltage. Screen control 70 is then adjusted to produce a " just discernible " line on the screen which is then " just extinguished " by operation of control 70 after which potentiometers 56, 57, 58 are adjusted to produce a low-brightness white line. Switch 30 is then returned to the " Normal " position and the drive controls are adjusted to produce the desired colour temperature (e.g. 9300 K.) of a white raster. Component values are given.

Title: Process of refining gasoline and other liquid petroleum products
IPC: C10G19/06
Filed: 1949-03-10
Abstract: <PICT:0668089/III/1> Mercaptans are eliminated from gasoline and other liquid petroleum products by washing first with caustic soda solution until all the mercaptans soluble in the aqueous phase have been eliminated, and then with sodium plumbite solution, and finally treating the hydrocarbon phase with air at a raised temperature, for example 120 DEG  to 150 DEG C. but at a sufficient pressure to keep the hydrocarbons in the liquid state, to oxidize the mercaptides to disulphides.  As shown in Fig. 1, caustic soda washed gasoline from pipe 1 is treated in a static mixer 2 with a sodium plumbite solution.  The gasoline layer separated in the decanter 4 is passed through pump P. and with introduction of air at 5, is heated in mixer 6 to 130 DEG C.  The gasoline decants into vessel 7 from which it is removed by pipe 9, and the lead oxide sludge separated in the decanter 7 is passed through line 10 to mixer 11 together with the spent plumbite from decanter 4.  Gasoline is separated in the decanter 12 and removed at 13, and the regenerated plumbite solution removed at 14 is returned to the tank 3.  A modification of the invention in which the gasoline is distilled after the plumbite treatment in the absence of air and the heavy residual fraction only is treated with air, is described with reference to Fig 2 (not shown).
