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.
摘要翻译：用于驱动UHF电视调谐器等的调谐指示盘的小型减速机构包括具有刚性固定花键和可动柔性花键构件的谐波驱动单元。指示盘被机械地联接到柔性花键构件，并且波发生器附接到选择器轴。选择每个花键上的齿数使选择轴和指示盘之间的减速比大约为7：1。在柔性花键上设置比刚性花键更多的齿，以防止在使用小于约20:1的减速比时通常发生的花键之间的结合。

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 70 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. Facilities are provided in such a UHF tuning arrangement for disabling an associated AFC control circuit during periods when the selector shaft is moved between said detent positions and during periods when a fine tuning adjustment is being made.

摘要： A compact dial indicator arrangement is provided for a UHF tuner of the type having a continuously variable main tuning shaft and a station selector shaft provided with detent means for establishing a separate detent position for each of the 70 television stations in the UHF band. An elongated strip of material bearing numbers corresponding to each one of the 70 UHF television stations is moved past a viewing position at which the selected channel numbers may be viewed by means interconnected with the detented selector shaft so that the number on the elongated strip corresponding to each stop position of the continuously variable main tuning shaft is automatically viewable at the viewing position in response to rotation of the selector shaft to each detented position thereof.

摘要： A system is disclosed for controlling the illumination of the channel or station selection indicator of a receiver of the standby type. The receiver includes at least one tube having a cathode filament. During standby operation one half power is supplied to this filament via a diode. During normal operation the diode is shorted out, so that full power is supplied to the filament. The channel or station selection indicator lamp is connected in series with another diode, the series circuit being connected across the cathode filament and the two diodes being connected with reverse polarity so that flow of current through the lamp during standby operation is inhibited but is permitted during normal operation of the receiver.
摘要翻译：公开了一种用于控制待机类型的接收机的信道或站选择指示符的照明的系统。接收器包括至少一个具有阴极细丝的管。在待机状态下，通过二极管向该灯丝提供一半的功率。在正常工作期间，二极管短路，从而向灯丝提供全功率。通道或站选择指示灯与另一个二极管串联连接，串联电路连接在阴极灯丝上，两个二极管以相反的极性连接，使得在待机操作期间通过灯的电流流量被禁止，但允许在接收机正常运行。
