Nikola Tesla Patents
534 112, 034.--2. it is not seen how these vibration can be reflected in such manner as to produce the phase relation necessary to stationary waves. Applicant is required to give some reasonable theory as to how irregularly distributed or incomplete reflections which alone. appear to be possible in the Earth can produce stationary waves, or else to prove conclusively by actual experiment that there are stationary waves. Proving merely that there are zones of elèctrical activity and intermediate zones of no activity does not prove the existence of stationary waves because such zones might be the result of some other cause such as irregular reflection or refraction. It is well known that there are sometimes zones of silence around a fog horn at sea but it is not known that this fact was ever taken as proof of the existence of stationary sound waves. In any event it is not seen why if stationary waves are produced in the Earth in this case similar waves would not be produced by the devices described in applicant's patents, 645,576, March 20, 1900, 649,621, May 15, 1900, 685,953 and 685,955, Nov 5, 1901, Telegraphy, Wireless. Whether this be so or not, it would seem that the transmitter in this case differs from that of the other merely in a matter of unsubstantiated theory and that the grant of a patent in the present application would amount to an illegal extension of the monopoly already granted. The claims are rejected as being inoperative except in such particulars as are anticipated by said patents and also by the British patent to Braun, 1,863 of 1899, Telegraphy, Wireless. GRu, G.C. Mean Examiner, Div. 16.
