Abstract
Abstract A rotary exchanger in which the thermodynamic characteristics of two gas currents are transferred from one current to the other while they are being passed through the exchanger body in zones separated from one another while it is being rotated within a casing, adjustable sealing means being provided between the exchanger body and the casing to define the separate zones from one another.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
180 words
A wheel-like transferrer of thermodynamic characteristics of a plurality of air streams comprising: a. a rotary transferrer body housed within a casing and composed of a plurality of thin corrugated sheets of fibrous material which engage one another at spaced intervals to form a mass of open-ended axial extending passages, the end portions of which passages form substantially flat faces at each end of said rotary body; b. sealing means in said casing defining separate zones through which the air streams are passed in thermodynamic heat exchange relationship with one another; c. said sealing means comprising a support surface perpendicular to the flat surfaces of the exchanger body, a sealing strip and a resilient clamping means for holding the sealing strip against the support structure while allowing the sealing strip to yield under a force exerted in a direction parallel to said flat surfaces and in the direction of rotation of the transferrer body so as to floatingly adjust themselves in response to irregularities in said flat faces and to the play of the transferrer body during the rotation thereof.
