1929 T. T. Brown in Sci. & Invention Aug. 375/1 Every material body possesses..distinct energy levels corresponding to the gravitational influences of every other body. These levels are readily revealed as the electro-gravic impulse dies and as the total gravic content of the body is slowly released.]

1956 Interavia 11 373 An electro-gravitic field acting on all parts simultaneously.

1960 B. S. DeWitt & R. W. Brehme in Ann. Physics 9 222 A plane or spherical sharp pulse of light, when propagating in a curved 4-dimensional hyperbolic Riemannian manifold, does not, in general, remain a sharp pulse, but gradually develops a ‘tail’. It is this phenomenon which is responsible for the electro-gravitic bremsstrahlung.

1989 Proc. Royal Soc. A. 423 455 The general electrogravitic differential is the sum of an electric differential and a pure gravitic one.

1998 UFO Mag. Jan.–Feb. 21/2 The new Lockheed-Martin space shuttle (National Space Plane) and the B-2 (Stealth bomber) both have electro-gravitic systems on board.
