DEFINITION

Classification: 315/5.39

(under subclass 5) Subject matter including a plurality of hollow distributed parameter devices with the ray passing through or in at least two of the devices.

(1) Note. For classification here the ray must pass through or in at least two of the devices. A system of two devices with the ray passing through or in only one device, the other device being merely coupled to the ray as by being connected to the cathode and control grid, without the ray passing through or in the other device is not classified here, but elsewhere under subclasses 5+.

5.14+, for one or more hollow distributed parameter devices with a plurality of rays passing through or in and especially indented subclasses 47+ for a plurality of such devices.

5.27, for plural hollow distributed parameter devices, one of which deflects the ray passing through or in.

5.28, for plural hollow distributed parameter devices, where the ray passing through or in is deflected.

5.33, for plural distributed parameter devices, one of the devices being a ray anode or cathode. 5.51, for a hollow distributed parameter device with the ray passing through or in, the device having a plurality of gaps.
