(under subclass 326) Electrodes and shields which are composed of a plurality of parts or sections, one of the parts or sections being composed of a different material from the material of which another part or section is composed.
(1) Note. This and the indented subclasses includes the structure of electrodes and shields which are formed of one material and which are coated with another material.
(2) Note. This and the indented subclasses do not include electrodes or shields which are composed of a plurality of materials which are mere constituents of a single composition or alloy.

337+, where the electrode is an indirectly heated cathode.
343, for this subject matter where the electrode is a filament or resistance heated electrode which has a wire or strand wound upon another filament or rod which is of a different composition from the composition of the filament or rod. 346, for this subject matter where the electrode is made of a material containing or is coated with electron emissive material or includes a body or mass of electron emissive material which is at least partly enclosed by a support or carrier which is permeable to electrons or to the electron emissive material.
