Abstract
203,716. Waite, H. G., (Assignee of Boursin, A. C.). Sept. 11, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic amplifiers and detectors; receiving sets, constructon of.-A receiving set comprises an inductance L, Fig. 1, the slider c of which moves opposite a scale R which is adjustable for calibration. Further flat inductance coils L<1> - - L<5> may be switched in by the switch m<3> and any one of the condensers 1, 2, 4, 1, or any pair of adjacent ones may be cut in by the switch m<2>. The terminals E<1>, E<2> are for the substitution of a frame for the antenna A. The terminals S<1>, S<2> are connected to the terminals S<1>, S<2>, Fig. 2,. and a switch M is arranged to connect them to a telephone E direct or through a four-valve amplifier. A further switch N is arranged to cut out the last two valves. The first grid may be capacity-coupled to the second plate for self-heterodyning.
