DEFINITION

Classification: 315/5.37

(under subclass 5) Subject matter wherein the hollow device is provided with a grid and significant ray reacting details of this grid are claimed.

(1) Note. The grids of this subclass are only those which are associated with the device at its gap, and through which the ray passes. Accelerating or focusing grids disposed along the ray path but not an intimate part of the hollow device, are not within the scope of this subclass.

Subclasses 5.34+ and 5.41, respectively, provide for ray focusing and concentrating and ray accelerating between hollow devices generally within the scope of subclass 5.

(2) Note. A hollow device provided with a mere plurality of grids is not considered to be a significant grid detail for classification here. A particular relationship between the plurality of grids must be claimed or significant details must be claimed for classification in this subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.11+, for a hollow distributed parameter device having a ray passing through or in together with a secondary emission grid.

5.24+, for a hollow distributed parameter device wherein a grid deflects the ray passing through or in. 5.29+, for a hollow distributed parameter device with a ray of a particular transverse shape or electrical dimension passing through or in, the grids of the device having openings shaped to pass a ray of such shape or dimension.

5.34+, for a hollow distributed parameter device wherein grids generally focus or concentrate the ray passing through or in. See also (1) Note above.

5.36, for a hollow distributed parameter device through or in which a ray passes, the device being removable from its grids.

5.41, for hollow distributed parameter devices with a grid for accelerating or decelerating the ray between the devices. See also (1) Note above.
