788 371,817 2. cuit in which the charge is oscillating. It is immaterial so far as the protective action of the terminal is concerned whether the charge is at rest or rapidly oscillating. A copy of the 11th edition of Ganot's Physics, referred to in the last Office action, may be seen in the examirer's room, Division 16, of the Patent Office. Figure 669 shows a discharge terminal consisting of a series of cortiguous spheres in alignment and successively smaller in diameter. Figure €71 shows a coil of close turns of insulated wire placed in the discharge circuit of e' Leyden jer end supported. upon an insulating stand. The figure also shows a needle to be magnetized and inserted in the open coil. claims 2, 3, 20, 21 and 22 are rejected upon Figure 671 of Ganot. It is held that there would be no invention in employing such a coil as that here shown in an oscillating or resonant circuit. Claims 7, 8 and 9 are rejected upon Figure 669 of Ganot. The discharge spheres shown in this figure are supported at points of relatively low electrical density. Claim 14 is rejected upon Shoemaker, Lodge or Stone, of record, as per lest Office action, and claims 15, 16, 18 and 19. are rejected upon Shoemaker or Lodge. Applying Shoemaker to claim 14, for instance, the part of the antenna and ground circuit, Figure 1, which contains the spark gap is that pert upon which oscillations are impressed, while the element 1 constitutes a part of the circuit for raising the tension by resonance. It should be noted that the type of capacity area shown in Figure 2 may be used in place of that of 90 371 94
