Filed: 1937-01-28
Abstract: 466,014. Wireless signalling; valve detecting circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Jan. 28, 1937, No. 2557. Convention date, Jan. 28, 1936. [Class 40 (v)] In a two-way signalling system in which reception is effected by heterodyning the received waves with those transmitted to produce an intermediate frequency, corresponding to decimetre waves are used and a diode detector is used for the frequency changer and constitutes part of the tuned receiving circuit. The Figure shows a transmitting oscillator O which may be modulated from transformer Tr and a diode frequency changer G feeding an intermediate frequency amplifier Z. The oscillator is connected to a Lecher wire system L coupled to a line B serving as feeder to the aerial A. The loop D which with the diode capacity forms the tuned receiving circuit may be replaced by bends in the ends of the feeder wires. The aerial may be inductively coupled to the detector, the loop in parallel with the diode being coupled to a loop at the end of the feeder, a half wave length line being inserted if required. The feeder B may be adjustable in length by the inclusion of a telescopic portion or a trombone slide so that waves reflected from the diode are in the same phase as waves from the oscillator. Alternatively an adjustable branch line may be provided to effect tuning. The frequency of the oscillator may be varied by a member gang controlled with a member adjusting the length of the feeder. The oscillator may be a magnetron and may be modulated by a buzzer to enable tuning to be effected, since only when the station to be received is tuned correctly, will the intermediate frequency be produced.
