DEFINITION

Classification: 455/899

MISCELLANEOUS:

(under the class definition) Subject matter relating to systems, instruments, or elements specific to modulated carrier wave communication and not provided for in any of the preceding subclasses of this class.

(1) Note. Communication by protons, muons, or neutrinos is included here.

SEE OR SEARCH CLASS

174, Electricity: Conductors and Insulators,

32+, for anti-inductive structure with shields or screens; subclass 46 for apparatus wherein an extension power cord forms the handle of a portable radio cabinet; subclass 50 for boxes and housings including radio cabinets which are limited to electrical use, see indented subclass 52.1 for such boxes and housings where the box or housing has an electrical device such as radio apparatus cited by name only, or mounting a broadly recited electrical device therein. Wherein the claims specify that the box contains two different apparatus, even though recited by name only, such as a power supply and a tuning stage, the patent will be found in Class 361, Electricity: Electrical Systems and Devices, subclass 814 where no circuit connections between the apparatus is claimed which significantly limit the apparatus to use as a radio apparatus.

178, Telegraphy, appropriate subclasses for telegraph apparatus.

181, Acoustics, 148+, for diaphragm mounted in a cabinet.

200, Electricity: Circuit Makers and Breakers,

51+, for electric connectors, including vacuum tube sockets, which have an electric switch structurally combined therewith.

250, Radiant Energy,

250, for radio wavemeters; subclass 305 for electron energy analysis; subclasses 336.1+ for invisible radiant energy responsive electric signalling; subclass 423 for ion generation; subclass 489 for ion collectors; and subclasses 200+ for photocell circuits and apparatus.

312, Supports: Cabinet Structure,

7.1, for cabinets designed to house radio apparatus. See (1) Note to subclass 7.1 of Class 312 for a statement of the subject matter provided for in Class 312.

313, Electric Lamp and Discharge Devices, appropriate subclasses for electric space discharge devices (e.g., radio tubes), per se.

323, Electricity: Power Supply or Regulation Systems,

370, for structural combinations of condensers and grid leak-resistances.

327, Miscellaneous Active Electrical Nonlinear Devices, Circuits, and Systems, appropriate subclasses for miscellaneous circuits which may form components of or be used with the systems of this class.

329, Demodulators, appropriate subclasses for demodulators and detectors wherein the useful information which has been modulated onto a carrier wave is derived and utilized. 330, Amplifiers, particularly

65, for amplifiers including structural details.

331, Oscillators,

187, for miscellaneous oscillator structures.

334, Tuners, appropriate subclasses for tuner mechanism, per se.

338, Electrical Resistors,

70+, for mechanically variable electrical resistors mounted in or on a lamp socket which may be a vacuum tube socket; subclass 219 for fixed electrical resistors mounted in or on a lamp or tube socket or base; and subclasses 68+ for rheostats and potentiometers.

340, Communications: Electrical, appropriate subclasses, particularly

850+, for underwater apparatus and subclasses 870.01+ for telemetering systems.

343, Communications: Radio Wave Antennas,

702, for antennas combined with a radio cabinet. See also (3) Note, subsection D, under subclass 700. 361, Electricity: Electrical Systems and Devices,

600+, for miscellaneous arrangements of apparatus mounted on a panel, within a box; or other mounting on a panel, within a box or other mounting, including a radio chassis. See the reference to Class 174 above for a statement of the type of apparatus found in Class 361. See subclasses 306.1+ for the structural combination of an electrical condenser, including vacuum tube sockets and an electric condenser. The condenser may be connected to only one or less than all of the socket terminals. Also included in subclasses 306+ are condenser connector combinations where the connector is for the purpose of mounting another electrical device to the condenser, such as condensers with means for mounting and connecting a grid leak in circuit with the condenser. See the reference to Class 323, Electricity: Power Supply or Regulation Systems, for condenser-grid leak resistance combinations.

367, Communications, Electrical: Acoustic Wave Systems and Devices,

95+, and 133 for compressional wave control systems.

379, Telephonic Communications, appropriate subclasses for telephone apparatus.

439, Electrical Connectors, appropriate subclasses for electrical connectors arranged on a panel with preformed circuit conductors and for devices in which a panel or chassis has connectors such as vacuum tube sockets mounted thereon.
