摘要： A tuner for use in a telecommunication receiver having a rotary drum carrying a plurality of oscillation coils and a fine tuning member for each coil supported for movement inside of the coil for fine tuning and having a geared head, and a main shaft on which the rotary drum is rigidly mounted, and a fine tuning mechanism which has a hollow shaft coaxially mounted on the main shaft for movement between projected and retracted positions and having a drive gear mounted thereon and a transmission gear assembly for transmitting the rotational force of the hollow shaft to the geared head of any one of the fine tuning members. The transmission gear assembly is supported by a support plate assembly.

摘要： The base portion of the wiper contact is deformable to assure continuous electrical connection between a lead screw and the aligned resistive strip located on the surface of the turret, as the contact is inserted therebetween. The strip engaging portion is located on the resilient base portion approximately midway between the guide portion and thread engaging portion such that the deformation causes the contact to exert substantially balanced forces on the lead screw. The structure of the guide portion of the contact is designed to enhance mechanical stability by preventing dislodgement of the contact without the necessity for cooperation with other external parts which obstruct visibility of the position indicating member, which is mounted on the contact and extends over the entire width thereof. In addition, means are provided to prevent the relative lateral movement between the contact and the lead screw during lead screw "runoff".

摘要： A flexible fabric sling-type wiping member is described for application against longitudinally-extending sets of electrical contact points of tuner strips in a rotary drum tuner for wipe cleaning the points as the tuner is rotated during use while changing from channel to channel. A flexible woven fabric is supported in embracing, sling-like fashion over a substantial portion of the periphery of the rotary drum tuner and supported thereat by the tuner drum housing.

摘要： Included in a step-by-step VHF tuner are three small rotor assemblies, such as turrets, mechanically intercoupled in sideby-side relationship and each having a series of tuning elements selected ones of which are rendered effective in different angular positions of the rotor assembly to achieve tuning to different VHF television channels. To effect rotatable mounting, each rotor assembly has an open-center hub journaled in apertures of a pair of parallel support plates, such as opposite walls of the tuner housing. A channel selector shaft may be inserted into and keyed to the hub of any one of the rotor assemblies to effect simultaneous rotation of all three. One of the hubs, other than that receiving the tuning shaft, may be open along its entire axis to provide an access opening through the tuner to permit control of other functions in the receiver, such as control of a UHF tuner.
