Abstract

684,949. Electric remote control. STANDARD TELEPHONES & CABLES, Ltd. April 12, 1946 [April 18, 1945] No. 11328/46. Class 40 (i) [Also in Group XL(c)] In a radio system suitable for the remote control of a glider, a transmitted carrier wave is modulated by a selected one of a number of pulse-modulated sub-carrier waves. By using pulses, more power is available and detection is more difficult. When one of the glider controls is to be operated or its controls restored to normal by one of the relays 5 ... 9, a control lever 3 energizes relays to produce one or more pulses at 10 and to insert one of five inductances in the circuit of an oscillator 12. Sub-carrier and principal oscillators 12, 18 are keyed by the pulse generator 10 and the oscillator 18 is plate-modulated by the output from 12. The modulated principal carrier wave is radiated from a broad band aerial 20 received by the glider aerial 21, amplified in a broad band amplifier 22, and fed to a detector 23. The output from 23 is fed through a high pass filter 24 and amplifier 25 to five separate channels 26 . . . 30, each comprising a selector filter 31 designed to pass one of the five sub-carrier frequencies. The output from a selector filter is fed through a threshold clipper 32 and an integrator 33 to the required relay. The Specification suggests 200-microsecond pulses, subcarrier frequencies within the 1-2 or 2-3 megacycle band and a principal carrier frequency of several hundred megacycles.
