Abstract
578,876. Wireless receiving apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., and KINMAN, T. H. Jan. 1, 1942, No. 51. [Classes 40 (iii) and 40 (v)] A mixing circuit operating at ultra-high frequencies comprises a hollow resonator 1 including a probe 3 extending into the resonator and having a variable gap for tuning the resonator and carrying a crystal detector 17 connected to the output circuit. The probe is associated with two other electrodes in adjustable relation thereto which are fed with the signal and local oscillations respectively. Fig. 1 shows an arrangement in which the probe 3 is coaxially and insulatingly mounted on the resonator to provide a small capacity thereto. The electrodes 9, 13 are insulated at one end from the resonator and carry segmental and rectangular members 14, 10 respectively, but may, alternatively, carry a loop or a cranked portion which may be a multiple of a quarter wavelength. As shown, the signals are fed through a concentric feeder 6 made with an adjustable bend 17 for matching. Alternatively, the trombone adjustment may be replaced by insulating tubes or slugs 19, Fig. 3, and the local oscillation fed to a probe or loop electrode 23 arranged at right angles to the resonator.
