DEFINITION

Classification: 315/5.14

(under subclass 5) Subject matter wherein each of a plurality of distinct rays pass through or in a single hollow device.

(1) Note. A plurality of rays exit as when projected from separate or distinguishable cathodes. When a single cathode projects a ray which is broken into a plurality of pencil rays as by an apertured mask or other dividing structure, these pencil rays are not considered plural for purposes of classification in this subclass. When two distinct cathodes produce each a ray which merges over at least a part of the ray path, classification is not barred from this subclass. See especially indented subclass 5.15. A mere plurality of structures each having a hollow distributed parameter device with a ray passing therethrough is not classified here, but elsewhere under subclass 5.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.12, for a hollow distributed parameter device with a ray passing through or in, and a second ray also passing through or in and produced by the first ray through secondary emission.

5.13, for magnetrons having a ray passing through or in the hollow distributed parameter portion.

5.18+, for a hollow distributed parameter device, where the

ray, after passing through or in, returns to the hollow device, and especially indented subclass 5.23 where the device is thermally tuned as by a cathode-ray. 13.1, for plural ray cathode-ray tube circuits generally.
