Abstract: A universal T.V. channel knob has a channel indicator skirt slidably receivable on a cylindrical, molded synthetic plastic knob shaft and relatively attachable thereto in an infinite number of rotative positions to provide for universal replacement usage. A metal, radially depressable slide pin is provided for securing the dial skirt in adjusted rotative position with respect to the knob shank with only minimal projection inwardly along its mounting shank, thereby minimizing any possibility of interference with fine tuner knob assemblies and the like that may be coaxially arranged in close proximity behind the T.V. channel knob assembly.

Abstract: An indicator bar assembly for an automobile radio in which a reflector surface of the slidable indicator bar reflects light through one of a plurality of separately colored plastic fixed indicators to indicate the radio station to which the radio is tuned.

Abstract: 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.

Abstract: A channel indicator device for a television receiver set or the like, more particularly a channel indicator device for a click stop type UHF tuner such as one having 70 detents is disclosed, in which a knurled surface is formed on an inner surface of a tube of a channel digit indicator plate and a plurality of resilient members are mounted on a tubular shaft attached to an indicator shaft, the resilient members being formed such that the knurls are adapted to gear with said knurled surface, whereby the positional offset between the channel digit and a pointer may be readily adjusted.
