(under the class definition) Subject matter in which means, such as a detent or electrical braking circuit, is provided to check or arrest the motion of the tuner adjusting shaft or device at a preset position or at a given time.
SEE OR SEARCH THIS CLASS, SUBCLASS:
17+, for tuners driven by an electromagnetic operator and so constructed as to scan a band of frequencies and stop on a given signal within that band of frequencies. A signal seeking tuner is an example of the type of unit found in this group of subclasses.
30+, for circuits which indicate when a tuner is properly adjusted to resonance as, for example, the tuning in of a particular radio signal.
86+, for tuners having an indicator or dial to show the position or degree of movement of the tuner drive means.

74, Machine Element or Mechanism, 10.41, for shaft operated preselected position devices having detent or clicker means, and subclasses 527+ for detents, per se.
192, Clutches and Power-Stop Control,
116.5+, for mechanisms for stopping a machine when a preset condition occurs.
