DEFINITION

Classification: 313/596

Strip electrode:

(under subclass 595) Subject matter wherein the electrode between the two spaced electrodes is an elongated electrical conductor.

(1) Note. The strip electrode may be electrically connected to either of the two spaced electrodes.

(2) Note. The discharge devices here are generally double-ended tubes but the subclass is not restricted to such type tubes.

(3) Note. The two spaced electrodes are heated filaments, but the subclass is not restricted to electrically heated resistance electrodes.
