  • Patent number: 4128820
    Abstract: In a VHF tuner a stator bar switching arrangement is provided which is particularly suitable for use in combination VHF-UHF tuners. A movable switching member positioned on the main stator bar of a turret type VHF tuner is moved between fixed contacts on the stator bar by engagement with a projection on each of the tuning sticks of the turret in each VHF channel receiving position of the main selector shaft. Various switching arrangements are provided for VHF-UHF operation.

  • Patent number: 4054853
    Abstract: An electrical fine tuning system for a UHF television tuner utilizes a voltage variable capacitor for adjusting the operating frequency of the oscillator. The capacity of the voltage variable capacitor is determined by a potentiometer that is mounted concentrically with the selector shaft and serves as a fine tuning control. An automatic frequency control voltage may be applied to the voltage variable capacitor used for fine tuning or to a second voltage variable capacitor. Circuitry is provided for extending the tuning range of the voltage variable capacitor when a single voltage variable capacitor is used both for fine tuning and automatic frequency control, and an improved mechanical construction is used to couple the voltage variable capacitors to the oscillator.
