    Abstract: A method of increasing the useful seismic energy in a generated primary pulse and at least one article for carrying out the method is disclosed. The article comprises a pneumatic sound generator, as an air gun for generating a primary seismic pulse and an openended elongated cylinder surrounding the air gun and having an end opening are nearest the air gun exhaust ports greater than the area of said ports for shaping the primary pulse so that its dominate frequency will be lowered, placing more of the energy in the useful seismic frequency range, resulting in greater penetration of the seismic signal within the sedimentary section.

    Abstract: A method and at least one steam aspirating gas flare for carrying out the method are disclosed for smokeless burning of undesired gas. The flare includes a steam control valve responsive to a new very low gas flow detector utilizing a knockout drum water seal, a by-pass line with an orifice run, and a water level switch for supplying an empirically set fixed flow of steam to the flare for ensuring a smokeless flame prior to the gas flow rate reaching a measurable rate. A full range flare including all other gas flows includes also several steam flow valves, each valve being empirically set to provide the proper steam-to-gas ratios throughout its respective range responsive to several corresponding gas flow detectors for ensuring a smokeless flare as the flare gas flow varies from the immeasurable ranges through the measurable ranges of the detectors.

    Abstract: Disclosed is a system for minimizing distortion in the continuity of the input energy of a seismic energy generator. In a hydraulically operated oscillatory seismic generator, the continuity of the seismic energy input to the ground is affected by the valve operation. The present system employs a differential pumping system to control the pressure input to the hydraulic seismic generator without requiring valves thereby eliminating distortion due to valves.

    Abstract: A METHOD OF DISPOSING OF CERTAIN PROCESS EFFLUENT WASTE STREAMS BY INJECTING THEM INTO SUBSTERRANEAN FORMATIONS WHICH ENTAILS INHIBITING THE FORMATION OF SOLID PRECIPITATES WHICH PLUG THE SUBTERRANEAN FORMATION. THE METHOD OF INHIBITING THE FORMATION OF PRECIPITATES INVOLVES LOWERING THE PH OF THE MIXED STREAMS AND OPTIONALLY REMOVING ANY ORGANIC PHASE CREATED THEREBY BEFORE INJECTION.
