Abstract
A seal construction and rotary processor including the seal construction in which the seal includes nested truncated conical members of thin stiffly-resilient material interposed between relatively rotatable coaxial surfaces with inner edge portions of the members adjacent and in flow resistant relation to one, and outer edge portions adjacent and in flow resistant relation to the other of the surfaces, marginal portions at either the inner or the outer edge portions of the loops being held to enable pressure against the loops to force the outer or inner edges respectively into improved sealing relation to the surface to which they are adjacent.
