(under subclass 434) Apparatus in which the surface means comprises at least two plates between which the gas flows in a tortuous or sinuous path, said plates being bent, deformed or provided with projections, and arranged relatively one to the other so that a bend, deformation or projection of one plate is spaced from the corresponding bend, etc. of the other, so as to provide substantially constant area for the gas flow.
