608.~ Single electrode type discharge device, or including particulate material


DEFINITION

Classification: 313/608

Single electrode type discharge device, or including particulate material:

(under subclass 567) Subject matter which include discharge devices having only one electrode; or which have a space

between two electrodes which is at least partially filled with particulate material.

(1) Note. When the discharge device has but one electrode and the voltage to operate the device is applied between the single electrode and some other object, such as ground, the electrostatic field at the discharge device along with the gas pressure and the device structure is capable of causing ionization of the gas or vapor within the device.
