摘要： An operator-controllable detent mechanism is provided for a combination VHF-UHF television tuner. Separate torsionally-loaded detent springs are provided for two detent wheels which are mounted on the common station selector shaft of the tuner. A manually-operable control member concentric with the selector shaft is employed selectively to remove the torsional load on one detent member or the other so that the common selector shaft may be detented for combined VHF-UHF reception, VHF only reception or UHF only reception.

摘要： A compact speed reduction mechanism for driving a tuning indicator dial of a UHF television tuner or the like includes a harmonic drive unit having a rigid fixed spline and a movable flexible spline member. The indicator dial is mechanically coupled to the flexible spline member and a wave generator is attached to the selector shaft. The number of teeth on each spline is selected to give approximately a 7:1 reduction ratio between the selector shaft and the indicator dial. More teeth are provided on the flexible spline than the rigid spline to prevent binding between the splines which normally occurs when reduction ratios of less than approximately 20:1 are used.

摘要： A pair of stator contacts, which are positioned inside the tuner housing and are internally connected to the AFT circuit within the tuner housing, are positioned so that unused tuning coils carried by the station selector shaft of the tuner are momentarily connected to this pair of stator contacts as the station selector shaft is moved from one detented channel position to the next. Each time a tuning coil is connected to the AFT circuit it defeats the AFT operation thereof and prevents the AFT circuit from controlling the local oscillator until the next detented channel position is reached. When the station selector shaft reaches a detented channel position at least one of the pair of stator contacts is not connected to any of the tuning coils of the tuner so that the AFT circuit is free to control the local oscillator in a conventional manner.

摘要： A highly accurate UHF television tuner utilizes an improved housing and an improved mounting system for securing the tuning rotor and stator within the housing. The housing is fabricated from sheet metal that is welded at the corners to provide mechanical rigidity, and soldered at the corners to provide a good electrical contact. A cover is placed over an open end of the housing and soldered at the corners further to increase the mechanical rigidity of the housing. The depth of the housing is increased to reduce the effects of the housing on the tuner elements. An eyelet is mounted in one end of the housing for supporting the rotor shaft, and the stator is mounted by insulating posts that are inserted through sleeves integrally formed in the housing. An improved contact for more effectively grounding the rotor shaft to the housing is provided, and an improved detenting system is provided for the selector shaft to reduce the effects of inertial creep. An improved method is provided for mounting the rotor plates to the rotor shaft and for mounting the stator plates to the housing to improve the accuracy of alignment between the rotor and stator plates.

摘要： A continuously variable UHF tuner arrangement is provided wherein a single channel selector shaft is provided with a detent position for each of the seventy UHF television stations and a highly accurate detent mechanism is employed to return the channel selector shaft to any one of said detent positions with extreme accuracy. As a result, the tuning elements of the UHF tuner may be accurately aligned to different UHF stations corresponding to said detent positions and a nonambiguous digital dial arrangement is employed to indicate to the operator exactly which UHF station is being received. A masking member concentric with the selector shaft is provided with a viewing area in which only one member from cooperating tens and units dial members is simultaneously visible.

摘要： A combination VHF and UHF tuner is provided in which a common station selector shaft may be rotated a number of revolutions to cover the seventy stations in the UHF band. The common selector shaft is provided with twenty-four detent positions per revolution and in alternate positions of the shaft the twelve VHF stations in the VHF band are received. As the common selector shaft is rotated through several revolutions the VHF stations are repeatedly received but are interspersed with different individual stations in the UHF band. Accordingly, no matter what UHF station is being received, all of the VHF stations are always within one turn of the common selector shaft. In many mixed UHF-VHF reception areas a single turn of the common selector shaft is sufficient to select all of the UHF stations as well as all of the VHF stations which are broadcasting in that area. Also, any UHF station anywhere in the UHF band is selected with the same ease of selection as the interspersed VHF stations so that true comparability between VHF and UHF reception is achieved.A single readout window is provided which displays alternately and sequentially each individual channel number, whether UHF or VHF, in numerals of identical size and legibility. A common fine tuning shaft for both UHF and VHF is provided concentric with the common station selector shaft. VHF fine tuning may be either of the memory or nonmemory type.
摘要翻译：提供了一种组合的VHF和UHF调谐器，其中公共站选择器轴可以旋转数圈以覆盖UHF频带中的七十个站。公共选择轴每转提供二十四个制动位置，在轴的交替位置接收VHF频带中的十二个VHF站。当公共选择轴旋转几圈时，VHF站被重复接收，但是在UHF频带中散布有不同的个别站。因此，无论什么UHF站正在接收，所有VHF站总是在公共选择轴的一圈之内。在许多混合的UHF-VHF接收区域中，普通选择轴的单圈足以选择所有UHF站以及在该区域正在广播的所有VHF站。此外，UHF频带中任何地方的任何超高频站均选择与散置的甚高频台相同的选择，从而实现VHF和UHF接收之间的真实可比性。提供单个读出窗口，其以相同尺寸和可读性的数字交替地和顺序地显示每个单独的通道号，无论是UHF还是VHF。 UHF和VHF的普通微调轴与公共站选择轴同心地提供。 VHF微调可能是存储器或非存储器类型。
