amount is consequently dependent on the energy conveyed to the receiver by one single impulse, it is evidently necessary to employ either a very large and costly, and, therefore, objectionable transmitter, or else to resort to the equally objectionable use of a receiving device too delicate and too easily deranged. Furthermore, the energy obtained through the co-operation of the impulses is in the form of extremely rapid vibrations and, because of this, unsuitable for the operation of ordinary receivers, the more so as this form of energy imposes narrow restrictions in regard to the mode and time of its application to such devices. To overcome these and other limitations and disadvantages that have heretofore existed in such systems of transmission of signals or intelligence, and to render. possible an investigation of impulses or disturbances propagated through the natural media from any kind of source, and their practical utilization for any purpose to which they are applicable, I have devised a novel method, which I have described in a pending application filed June 24, 1899, Serial No. 721,790, and which, broadly stated, consists in effecting, during any desired time interval, a storage of energy derived from such impulses, and utilizing the potential energy so obtained for operating a receiving device. My present invention is intended for the same general purposes, and it comprises another apparatus by means of which similar results may be obtained. Po The chief feature, which distinguishes the method of my present from that of my former invention just referred to is, that the energy stored is not, as in the former -5[This page retyped from microfilm for better readability - Ed.] 465
