724 Per D 11 . D D D D Inzeil D12 Ver D sions, a self-inductor joined in series with an energizing circuit and having its outer boundaries arranged in a manner to prevent, on any of them, an excessive rise of the electrical surface density, as above described. set forthe In apparatus for the production of powerful electrical oscillations, a self-inductor joined in series of the kind described, with an energizing circuit and a free terminal and having the elements of its outer surface disposed in space in a manner to prevent, on any of them, an undue rise of the electric density, as set forth. In 42.43. an slement of a high potential transmitter or other apparatus for the production of high tensions, a a self-inductor supported on a place of relatively low potential to permit the accumulation of a great charge, and arranged in space so as to prevent the breaking out of A its surface charge, as set forth. 43. 44. As an element of high potential transmitter In hining relatively or other apparatus for the production of high tensions, a resonating circuit of relatively small linear dimensions and large outer surface/ the latter being of a configuration/ such as to minimize the effect of small curvatures in the distribution of the free charge, as described. 44.45 In apparatus for the production of high potentials, a self-induction coil supported on a place of relativethe ly low potential and extending to an elevated terminal, and having its turns sufficiently close to minimize the effect of the small curvature of the conductor, as set forth.
