Page 5 runs from subclass 250 through subclass 300, all within the woven fabric layers family indented under subclass 246. The entries classify woven fabric layers by the material they are impregnated with: natural or synthetic rubber under subclass 250; a thermosetting resin, hardening when subjected to heating conditions, under subclass 251, with phenolic resin — produced by condensing an aldehyde or ketone with a phenol or phenolate — under subclass 252 and epoxy resin — produced by reacting an epoxide, such as epichlorohydrin, with a polyol, such as bisphenol, or an alcoholate of one — under subclass 253; and a thermoplastic resin, rendered soft and moldable under heating conditions, such as vinyl polymer, under subclass 254.
Later entries cover three or more distinct layers under subclass 255 and the association of woven fabric with an additional layer formed by the deposition of animal, vegetable, mineral or synthetic fibers from a fluid suspension or dispersion, including paper layers — a mica paper layer under subclass 296 and plural paper or wood pulp layers under subclass 297. Links to all seven classification pages and back to the Government Resources directory let readers continue the series in either direction.
