Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
58 words
In combination: a vessel for containing a liquid, a cylindrical elastomeric resonator column having only one end thereof with a plate affixed thereto and disposed for acoustically coupling to contents within said vessel, the remaining portion of said resonator disposed outside of said vessel, and an orbiting mass oscillator affixed to the other end of said resonator column.
Claim 2
Dependent Claim
58 words
In combination: a vessel for containing a liquid, a cylindrical elastomeric resonator column having only one end thereof with a plate affixed thereto and disposed for acoustically coupling to contents within said vessel, the remaining portion of said resonator disposed outside of said vessel, and an orbiting mass oscillator affixed to the other end of said resonator column.
Claim 3
Dependent Claim
31 words
The combination of claim 1 wherein said vessel has a bottom surface provided with an opening therein, and wherein said one end of said resonator column is disposed within said opening.
Claim 4
Dependent Claim
18 words
The combination of claim 2 further comprising: a flexible sleeve extending from said vessel and surrounding said resonator.
Claim 5
Dependent Claim
53 words
The combination of claim 2 wherein said opening has a diameter slightly larger than the one end of said resonator so as to provide a small circumferential gap between said bottom surface and said one end, said gap having a width sufficient to cause any liquid therein to have a high acoustic impedance.
