744 371,817 - 2. Claims 13, 14, 28 to 34, inclusive, and 36 to 45, inclusive, are rejected on the ground that each is functional; said claims should be amended to include positively the essential elements necessary to produce the result recited in said claims. Claim 1 is rejected upon the device shown in Figure 721 of Genot's Elementary Physics, 15th Edition, Longmans, Green & Co., 1902. The pear-shaped surface which is shown here serves to collect a charge of high potential, and is supported by an insulator at a point of low electrical density. This device may be found in the earlier editions of Ganot's Treatise. Claim 1 fails to define from the Faraday spherical condenser as illustrated in Thompson's Elem. Lessons in Electricity and Magnitude, MacMillan Co., 1905, page 230. The sphere A is supported at a point of low electrical density. Claims 4, 5, 6, 7, 8,9 are rejected upon each of the references cited against claim 1. Claim 10 is rejected for the reason that it is incomplete and fragmentary. Claim 10 is further rejected upon the Farraday condenser, since there would be no invention in connecting Farraday's condenser in substitution of any condenser in the well known oscillating circuit. Claims 11, 12, 13, 14 to 45, inclusive, are each rejected on the ground recited in the rejection of claim 10, to wit, that it would not involve invention to substitute the Faraday condenser in the sell known oscillating circuit, which circuit may include the secondary of a transformer in the well known way. Claims 2 and 3 appear to be allorable. Lucke 3712/6 Acting Examiner, Division XVI. 48
