DEFINITION

Classification: 96/78

Adjacent parallel collector electrodes are differently charged:

(under subclass 77) Apparatus in which alternating collecting electrodes are charged to one potential (voltage) and the remaining plates to a second potential.

(1) Note. For example, if a positive potential is applied to the first alternating set, then either a negative potential or ground would be applied to the remaining electrodes, so that adjacent electrodes would be maintained at differing or opposite voltages.
