Abstract: ABSTRACT OF THE DISCLOSURE:           A process for controlling a distillation column in which feedstock is distilled for separation into a pro-duct from the top of the column having a first predetermined content of an intended component with a high boiling point and a product from the bottom of the column having a second predetermined content of an intended component with a low boiling point by controlling the flow rate of either one of the products and a part of the product from the top of the column is refluxed to the column.  The process comprises the steps of : computing a desired value of the flow rate of the product from the bottom of the column in accordance with a material balance;  controlling the flow rate of said product from the bottom of the column in accordance with a first corrected desired value which is obtained by correcting the desired value of the flow rate of the product from the bottom of the column in response to larger one of a first deviation between the first content of the intended component with a high boiling point and its desired value and a second deviation between the second content of the intended component with a low boiling point and its desired value when the control directions of the flow rate of said product from the bottom of the column by the polarities of the first and second deviations are same;  controlling the flow rate of said product from the bottom of the column in accordance with a second corrected desired value which is obtained by correcting the desired value in response to the second deviation when the control directions of the flow rate of said product from the bottom of the column by the polarities of the first and second deviations are different and controlling the reflux rate in response to a large one of the first and second deviations; and controlling the flow rate of said product from the bottom of the column in accordance with the limited values in a given range when the first and second desired values do not fall in said range and controlling the reflex rate in accordance with said limited values.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the simultaneous de-emulsifica-tion and de-asphalting of heavy oil/water emulsions containing asphaltics enables de-asphalted oil, asphal-tics and emulsion water to be separately recovered.  A heavy oil/water emulsion is mixed with a solvent to cause the emulsion to be broken with consequent dissolution of oil by the solvent and coalescence of emulsion water and asphaltics as fast settling particles, the solvent com-prising a light C4 to C7 paraffinic composition and the weight of solvent being from about 2 to about 5 times the weight of heavy oil.  The water/asphaltic particles are separated from the bulk of the oil/solvent phase and are fed into a water bath to produce relatively large stable asphaltic agglomerates with exclusion of emulsion water.  The asphaltic agglomerates are removed from the hot water bath, and de-asphalted oil is recovered from the oil/solvent phase.  Heavy oil containing asphaltics can also be treated by the process, with the separated asphaltics agglomerating in the hot water bath.

Abstract: DIRECTION-CONSTRAINED TERNARY CODES USING PEAK AND POLARITY DETECTION                Abstract of the Invention A class  of  ternary  square wave  signals  is detectable by peak polarity detection alone without need for amplitude discrimination.  The ternary codes are used to increase data density recording at the same clock rate as binary codes.  This is satisfied by selective direction-constrained run length limited (RLL) signals. The  direction  constraint  is  that  the  half-step transitions can only occur in pairs of the same polarity. Alternate half-step pairs of opposite polarity are forbidden.   This  avoids  the  need  for  amplitude discrimination.  The RLL (d,k) constraint includes "d" number of clock times when a transition is forbidden and "k > d" clock times within which consecutive transitions must occur.  The latter determines a minimum frequency for clocking purposes. This eases peak shift detection.

Abstract: SERIES CONNECTED SERIES MOTORS    FOR INDEPENDENT LOADS                                  ABSTRACT a traction drive system for a vehicle is disclosed which comprises a pair of series wound motors (32,34) which are connected in series with each other and which drive independent traction wheels (22,24), respectively, of the vehicle.  The no-load torque of each traction wheel is correlated with the transient torque characteristic of the motors so that each motor produces a transient driving torque greater than the threshold-load torque of the wheels.  Further, the no-load torque of each wheel is great enough so that the transient driving torque will not fall below the threshold-load torque during a predetermined time interval.  This arrangement permits one traction wheel to move the vehicle at low speed while the other traction wheel spins on ice or otherwise fails to exhibit tractive effort.

Abstract: METHOD FOR MONITORING THE QUALITY OF ZnSO4 ELECTROLYTE   CONTAINING Sb(V) ABSTRACT            Certain continuous methods for monitoring the quality of ZnSO4 electrolyte loose sensitivity when the electrolyte contains Sb (V).   The sensitivity can be increased by electrochemically reducing Sb (V).  A sample of electrolyte which contains impurities including Sb  (V)  and which may also contain polarization affecting agents is passed through a test cell containing an elongated moving cathode having a predetermined area exposed to the electrolyte,  an anode and a reference electrode.  A substantially constant current in the range of 0.01 to 0.20  A/cm2 is applied to the electrodes and the cathode is moved with a speed sufficient to obtain measured values of the cathode polarization potential of zinc deposition on zinc.  The measured values are related to the concentrations of impurities, polarization affecting agents, or both and to the concentration ratio between impurities and polarization affecting agents, and the process for zinc recovery is adjusted in response to these relations to obtain optimum zinc recovery.

Abstract: ABSTRACT:     A television transmitter comprises a video signal input (1) feeding a modulator (2), a pre-corrector (3), an up converter (4) and power amplification stages (5,6).  The stage (6), typically a Klystron amplifier, is operated in a non-linear mode to increase efficiency and the pre-cor-rector (3) is provided to provide a correction for the out-put amplifier stage non-linearity.  A portion of the output signal is coupled to a demodulator (8) whose output is fed to measurement means (9).  The measurement means (8) measures the distortion of the output, for example non-linearity, differential gain, etc., and applies a signal to a computer (11) via an interface circuit (10).  The com-puter then calculates control signals which are applied through the interface circuit (10) to the pre-corrector (3).  The control signals are effective to vary the trans-fer characteristic of the pre-corrector circuit (3) in such a manner as to reduce the output distortion to a min-imum value.
