DEFINITION

Classification: 96/75

Plural diverse electric fields:

(under subclass 15) Apparatus in which there are provided separate electric fields for separation or treatment of the gaseous fluid mixture (a) by different voltages, currents, or

electrode arrangements, or (b) by plural electric field separation units to provide effectively different electric fields arranged in the direction of flow of the gaseous fluid mixture.

(1) Note. A mere serial or continuous arrangement of electrodes to produce an elongated or repetitive field of one effective character is classified on some other basis.

54, for electric field separation apparatus using an alternating electrostatic field.

55+, for serially arranged, diverse type separators.

73, for flow regulating means for electric field separation sections in parallel flow arrangement.

83+, for electrodes supported or retained by a casing or duct wall and not including features of voltage regulation or special arrangements for electric fields.
