DEFINITION

Classification: 333/245

LONG LINE ELEMENTS AND COMPONENTS:

(under the class definition) Components and elements not constituting a complete network which are limited by claimed structure to use in long lines and which are not otherwise classified, and also long line elements.

(1) Note. Included in this subclass are structures and devices for modifying the characteristics of a transmission line at a particular location, for example, line short-circuiting switches, line-shorting plugs, impedance elements, and long line elements which are terminated in other than their characteristic impedance and are nonresonant (e.g., a short-circuited line 1/8 of a wavelength long).

13, for resonator type breakdown discharge device networks for short circuiting a long line.

22, for dissipating terminations for long lines.

101+, for branched circuits having switching means.

219+, for resonators.

236+, for long lines. SEE OR SEARCH CLASS

174, Electricity: Conductors and Insulators, appropriate

subclasses for conductors, housing insulators, conductor joints, and end structure where no significant wave propagation characteristic limiting the structures to use with long lines is claimed.

200, Electricity: Circuit Makers and Breakers, appropriate subclasses for switching structure in general.

285, Pipe Joints or Couplings, appropriate subclasses for couplings for coaxial lines or for waveguides where no significant electrical features are claimed.

329, Demodulators,

322, for a frequency demodulator including distributed parameter structure and subclass 354 for an amplitude demodulator including distributed parameter structure.

330, Amplifiers,

53+, for amplifiers with distributed parameter coupling means including subject matter involving structural details of such means.

343, Communications: Radio Wave,

907+, for antenna components.

439, Electrical Connectors, for transmission line electrical connectors where no significant wave propagation characteristic are claimed which limit the structure to use with long lines.
