648 23,847, 2. Nor is it seen how the arrival of such with respect to each other. impulses at the receiving station will necessitate the adjustment of the relays as stated. Applicant is required to

652 گر گیا اور ان کا : Evidently there are a great many ways of generating impulses or disturbances of any wave length, wave form, nunber or order of succession, or of any special character, such as

JLJ T Sub. Spec. ressure developed therein coincide with the elevated terminals D1 D2. The two systems may have electrical oscillations impressed upon them in any desired manner, converiently by

658 Sub. Afhen, X F each other that they are practically simultaneous, so far as the operation of such relays as R1 and R2 is concerned. Evidently, however, it is not necessary to employ two or more

J Bieli 92 9. In a receiving apparatus, the combination of a plurality of sensitive circuits, each tuned to respond to different waves or impulses of a given)kind or class, a receiving circuit

662 to Wilson is believed to be for a purely theoretical and inpracticable plan at best, but in any event it differs essentially from the Tesla plan in that the circuits of the receiver are both alike
