Class Information
Number: 429/129
Name: Chemistry: electrical current producing apparatus, product, and process > Current producing cell, elements, subcombinations and compositions for use therewith and adjuncts > Separator, retainer or spacer insulating structure (other than a single porous flat sheet, or either an impregnated or coated sheet not having distinct layers)
Description: Apparatus comprising a structure positioned between or for use between cell electrodes to physically or functionally separate the electrodes. Included in this subclass are separator, retainer, or spaced structures such as rods, buttons, frames, etc., which merely space the electrodes; separators which physically and functionally separate the electrodes and which enclose or envelop the electrodes or a portion thereof in any manner; structures having plural components; and sheet materials which have projection thereon.

Sub-classes under this class:

Class Number Class Name Patents
429/131 Having electrode enclosing feature 131
429/146 Having electrode spacing projections 53
429/142 Having plural distinct components 186
429/130 Insulator structure is only spacer of the rod, button, strip, or frame type 124
