Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A test chamber including an enclosure structure with a floor having a flexible sealing diaphragm, in combination with a vibrating unit disposed below said diaphragm and adapted to transmit vibrations through said diaphragm to articles within said enclosure structure, wherein the improvement comprises: a frame defining an opening in said floor normally receiving a support portion of said vibrating unit, said diaphragm extending across said opening and being supported at least in part on said support portion, said frame having at least one conduit passage normally receiving sealing means surrounding conduit means traversing said passage.
Claim 2
Dependent Claim
