(under subclass 1) Subject matter wherein a plurality of tuning units are mechanically and/or electrically built together, each of the tuning units mutually sharing a common tuning element with the tuning units being so constructed that they are operated in sequence one after the other by adjusting the common tuning element.
(1) Note. Subject matter usually found in this subclass consists of a cavity or resonator type tuner mechanically and/or electrically combined with an inductor-capacitor type tuning unit, the plunger or contact used to tune the cavity or resonator also being used to tune the inductor-capacitor type tuning unit. Thus the tuning element is mutually common to both type tuners.
SEE OR SEARCH THIS CLASS, SUBCLASS:
41+, for tuners of the resonant line or distributed parameter type.
65+, for tuners in which both the inductor and capacitor are variable and especially subclasses 66+ for tuners with a mutual inductor and capacitor varying element.
