Abstract: A quick action firing assembly for charging and sudden release of gas under pressure in a seismic energy generator for offshore subsurface exploration, for example, comprising a hollow, elongated valve having equal and opposite surfaces and means for charging the generator through the valve with high pressure gas and simultaneously applying equal forces in opposite directions to the valve whereby a minimum of force is required to open the valve.

Abstract: Methods for cleaning and manufacturing straight spring and filters for use at the petroliferous unconsolidated sand strata of an oil well, and a self-cleaning straight spring filter are disclosed. The filter comprises one or more sets of contiguous straight parallel closely spaced apart springs mounted around a perforated tube. With the spring upper ends fixedly secured around the periphery of the tube and the lower ends fixed to a ring encircling the tube and slideable in a longitudinal slot in the tube, the contiguous springs are closely spaced apart at a precise distance for filtering sand from sandbearing oil. A sleeve is slideable over one or more sets of springs to contact the ringed ends of the next adjacent spring set for scraping the calcification from the exterior surface of the springs, then the sleeves are moveable further to buckle and spread the springs apart for flushing and cleaning therebetween.
