Abstract

1,005,351. Tuning resonators. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. April 9, 1962 [April 7, 1961], No. 13513/62. Heading H1W. A UHF coaxial resonator 3 is capacitatively tuned by means of interleaving plates 6, 7 attached to the inner and outer conductors 1, 5, the movable plates 7 being mounted on leaf springs 9 attached to partition walls 2. They are moved by an insulating rod 8. The uppermost movable plate of each set 7 is provided with slits 10 whereby this plate may be shaped by bending to provide a desired change of capacity with movement of the plates. The inner conductors are supported by trimmer condensers 4.
