Abstract

A stack A of thin round flexible membranes 10 may be mounted with respect to a rotatable drive base 12 by spaced rods 14 fixed to base 12. The base 12 includes longitudinally extending air passages 16 extending through the stack A for the passage of air radially out of stack A, for maintaining membranes 10 in spaced relation with respect to each other.

Mounting Mechanism for a Stack of Thin Flexible Membranes

A stack A of thin round flexible membranes 10 may be mounted with respect to a rotatable drive base 12 by spaced rods 14 fixed to base 12. The base 12 includes longitudinally extending air passages 16 extending through the stack A for the passage of air radially out of stack A, for maintaining membranes 10 in spaced relation with respect to each other.

Membranes 10 have central openings 18 through them, and rods 14 are fixed to base 12 at 90 degrees with respect to each other about the center of rotation of base 12. Rods 14 extend through openings 18 and contact the inner edges of membranes 10 to hold stack A fixed with respect to base 12. Spacers 20 are provided between membranes 10, and each of the spacers 20 has four legs 20a each of which is provided with a slot 20b in its end for receiving one of the rods
14.

A cap 22 is fixed to the upper ends of rods 14 so as to clamp the membranes 10 and spacers 20 between cap 22 and base 12 into stack A. Base 12 is provided with air passageways 16a extending from the outer periphery of base 12 and into alignment with the passageways 16 extending through membranes
10. Cap 22 is also provided with air holes 16b that are in alignment with the passages 16 through membranes 10. The legs 20a of spacers 20 are so narrow that they do not substantially close the air passages 16 through membranes 10.

When base 12 is rotatably driven, membranes 10 are rotated along with base...
