Abstract: ABSTRACT OF THE DISCLOSURE     A composite sync signal is applied to an integrating circuit connected across the input of a normally conducting transistor.          The transistor is driven nonconductive by the serrated vertical sync pulse to develop the leading edge of a square wave timing pulse for initiating counting of horizontal lines in the vertical interval.  As the integrating circuit discharges, the transistor is driven conductive again to define the trailing edge of the timing pulse for initiating blanking of data on selected horizontal lines in the vertical interval.  Blanking of post equalizing pulses is avoided by having the trailing edge of the timing pulse occur after the post equalizing pulses.

Abstract: CYCLICAL STEAM FLOODING METHOD    FOR VISCOUS OIL RECOVERY                            ASTRACT          Viscous oil is recovered from a subterranean, viscous oil containing, permeable formation, penetrated by at least one injection well and at least one spaced-apart production well in which a fluid communication path exists or in which a fluid communicaton path is first established between the wells.  The method involves a cyclical pressurization-drawdown program in which initially steam is injected into the injection well at a predetermined rate and fluids including oil are produced from the production well at a restricted flow rate equal to a value 50 percent or less than the flow rate of the steam being injected into the injection well.  Steam injection and restricted production is continued until the wellhead temperature of the fluids is within the range of 175 to 250°F.  Thereafter, the drawdown phase begins by increasing production to a maximum value and simultaneously reducing the injection rate of steam to a value about 20 percent of the original injection rate until the oil content in the produced fluids decreases to an unfavorable level.  This sequence is repeated for a plurality of cycles until the desired oil recovery has been attained.

Abstract: ABSTRACT OF THE DISCLOSURE       Two or more sets of liquid substance feed means are provided each which consists of a supply device, a transport pipe and a delivery pump.  These feed means are connected through a valve to a single transport pipe and back pressure devices are provided in all but one of the liquid-substance feed means.  While a liquid substance is being fed by one of feeding means, another liquid substance having different properties is passing in the other feed means and using the back pressure device provided in the latter means, the flow rate and the pressure of the latter liquid substance are controlled as same as those of the former being fed by former feed means.  Being switched over, in this condition, from the former feed means to the latter to feed the latter liquid substance, two or more kinds of liquid substance having different properties can be fed sequentially at pre-determined pressure and flow rate.
