METHOD FOR MEASURING GRAVITATION CONSTANT AND DEVICE WHICH IMPLEMENTS SAID METHOD Russian patent published in 1998 - IPC

FIELD: gravimetric measurements. SUBSTANCE: method involves measurement of interaction gravitation force F1 using pumped torsion balance under condition that shutters of directed gravity generators are closed. Then method involves opening shutters by equal aperture in each directed gravity generators for time t which is greater than 10 minutes, closing shutters, measurement of gravitation force F2 between interacting bodies, subtraction of interaction gravitation force F1 from interaction gravitation force F2, calculation of gravitation constant using this difference, adding it to gravitation constant which is measured for closed shutters in order to achieve more precise value of gravitation constant. Corresponding device has pumped torsion balance with equal weight of bodies m1 and m2 located on balance beam, directed gravity generators which are made from non-magnetic material and have equal weights M1 and M2. They have housing which is made from material, which is not transparent to radioactive rays, and carries radioactive element which emits alpha particles and contains at least one curie of, for example, radon. It is located in perpendicular to interaction lines between mass centers of m1 and M1 and m2 and M2 respectively in each generator. Shutters which are located on opposite sides of radioactive element have remote control mechanism for opening and closing aperture. They are made from material which is not transparent to radioactive radiation in closed position. First blind wall, which is located on side of each shutter which is adjacent radioactive element, is made from material which can emit flow of unbound positrons under exposure to alpha particles. Second blind, wall which is located behind first wall, is made from material which provides interaction of unbound positron flow with its electrons. Stubs which are located behind second blind wall in each directed gravity generator are made from material is not transparent to radiation. EFFECT: increased functional capabilities. 2 cl, 2 dwg
