METHOD AND DEVICE MEASURING GRAVITATIONAL FIELD Russian patent published in 2004 - IPC

FIELD: study of gravitational field of the Earth. SUBSTANCE: method measuring gravitational field includes formation of screened electromagnetic field in gravitational field, location of sensor in it and determination of parameters of gravitational field by its readings. Current conducting medium with first pair of point feeding electrodes placed in symmetry is positioned in screened electromagnetic field in the capacity of sensor. Stable current is passed through medium with their aid. Second pair of separable electrodes placed in symmetry measures electric asymmetry voltage emerging across them under action of gravitational field, perpendicular to direction of flow of current in conducting medium. Potential of gravitational field is found from specified ratio. Device measuring gravitational field comprises sensor and recorder. Sensor comes in the form of dielectric tube filled with current conducting gas and housing two pairs of electrodes placed in symmetry and intended to connect one pair of electrodes to pulse generator fed from source of stable voltage. Recorder has amplifier connected to voltage source that sends signal of second pair of separable electrodes and sensor to digital meter. This pair is meant to measure asymmetry voltage emerging under action of gravitational field. Generator and digital meter are enclosed in heat and electric insulation screens, sensor is embedded in heat, electro- and magnetic insulation screens. EFFECT: decreased labor input, raised economic efficiency of gravitational prospecting for oil and gas fields. 3 cl, 3 dwg
