Claim 4
Dependent Claim
41 words
A cover assembly according to claim 2 in which the wall-sealing gasket comprises resilient sponge-like material adapted to fit and seal the space between the chamber wall and adapter frame despite possible irregularities in the surfaces of such wall and frame.
Claim 5
Dependent Claim
44 words
A cover assembly according to claim 1 having a cover-sealing gasket dimensioned to fit around such air conditioning unit in sealing engagement between the cover supporting flange and intermediate adapter frame when the cover is secured to the frame by said cooperating fastening means.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
42 words
A cover assembly according to claim 4 having a wall-sealing gasket dimensioned to fit around such chamber wall opening in sealing engagement between the chamber wall and intermediate adapter frame when the frame is secured in position by the first fastening means.
Claim 8
Dependent Claim
39 words
A cover assembly according to claim 6 in which the cooperating fastening means includes threaded members having manually operable grasping portions readily accessible along the cover-supporting flange when the cover and cover-sealing gasket are assembled with the adapter frame.
Claim 9
Dependent Claim
115 words
A cover assembly according to claim 6 in which the first fastening means comprises aligned openings around the periphery of the respective adapter frame and wall-sealing gasket, through which fastening screws may be inserted from the outer surface of the adapter frame into the chamber wall around such a chamber wall opening, and in which the cooperating fastening means includes outwardly-projecting threaded studs fixed around the periphery of the adapter frame, aligned openings in the cover-sealing gasket and cover flange to fit over the projecting studs, and retaining nuts for threaded engagement on the projecting studs, with the cover-sealing gasket and cover flange thereby adapted for clamped engagement between the retaining nuts and adapter frame.
Claim 10
Dependent Claim
