Abstract

259,005. Pearce, S. C., and Smith, J. S. Sept. 1, 1925. Receiving apparatus; non-thermionic amplifiers. - A crystal d in series with condensers f, f<1> is connected in the aerial circuit and an electromotive force applied across the crystal through an inductannce or choke c. In a modication a connection is taken from the lead between the detector and telehones k to the lead between the battery a and crystal d and in addition the other side of the telenhone is connected to earth. In a further modification an inductance is connected across the condenser f and coupled to inductances g, i.
