Abstract: An improved oil well pump timer including means for detecting periods of power outage and providing a pumping period following the outage of sufficient length to maintain an essentially constant duty cycle. Clock controlled timers determine preselected on and off cycle periods. Power failure detecting circuitry inhibits on timer operation and counts the number of off time cycles occurring during the outage. Upon reestablishment of power, control circuitry inhibits the off timer and provides a number of on time cycles equal to the number of off cycles during the outage.

Abstract: A multi-channeled digital seismic field stacking system is disclosed for obtaining the composite response to a variable source array. A variable source array is synthesized by applying preselected weighting coefficients to the seismic signals produced in response to a selected number of surface energy impulses. The seismic signals produced by these impulses are amplified, multiplexed and digitized to obtain digital samples to which are applied the weighting coefficients. A digital multiplier is used to multiply each digital sample by a weighting coefficient to obtain a weighted digital sample. Each digital sample is multiplied by two weighting coefficients, a partial and a final. The partial weighted samples from each of the impulses are summed together to form a partial stack, while the final weighted samples are summed together to form a final stack. The variable source array which is synthesized covers two station intervals.
