DEFINITION

Classification: 315/5.29

(under subclass 5) Subject matter wherein the ray has a cross sectional dimension which is significantly related to and an appreciable part of the wavelength of signal energy in the cathode-ray tube, and/or wherein the ray has a significant shape; the dimension and/or shape usually persisting over the entire path of the ray, and at least during passage through the device.

(1) Note. The patents in this main subclass (5.29) usually have a flat weblike ray.

(2) Note. The particular shape and/or dimension is usually produced by a cathode of particular shape and/or dimension; e.g. elongated, annular, or cylindrical cathode.

(3) Note. Subject matter including grids of distributed parameter devices which have openings peculiarly adapted to pass rays of a particular transverse shape or dimension are classified in this subclass, the ray or the means producing the ray being recited in the claim.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.14+, for a hollow distributed parameter device with plural rays passing through or in, the rays having a particular transverse dimension and/or shape.

5.24+, for a hollow distributed parameter device with a ray passing through or in, wherein the deflection of the ray provides a ray path having a particular shape or dimension, such as a particular bent or spiral ray. 5.37, for a distributed parameter device with a ray passing through or in, wherein the grids have a particular shape or dimension not related to the transverse shape or dimension of the ray. See (2) Note above.
