Abstract
Abstract A resonator comprising a plurality of rigid pivotable members are interconnected by a flexible member which is arranged to induce counterrotary movement of the rigid members upon driving of one of the members. In order to provide a resonator having a relatively low resonant frequency, the flexible member is relatively long and is connected to the rigid members on opposite sides of the nodal axes thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A resonator comprising first and second parts unflexing at a resonant frequency of the resonator; means supporting the first and second parts in a first plane to enable the parts to rotate about the nodal axes thereof, the nodal axes substantially intersecting the respective centers of gravity of the parts and defining a second plane perpendicular to the first plane; a third part outside the first plane, flexible at a resonant frequency, connected tO the first and second parts at first and second locations to induce counterrotary movement of the first and second parts upon driving of one of the parts, the first and second locations being substantially in the second plane with both nodal axes being between the first and second locations; and means for driving one of the parts.
Claim 2
Dependent Claim
131 words
A resonator comprising first and second parts unflexing at a resonant frequency of the resonator; means supporting the first and second parts in a first plane to enable the parts to rotate about the nodal axes thereof, the nodal axes substantially intersecting the respective centers of gravity of the parts and defining a second plane perpendicular to the first plane; a third part outside the first plane, flexible at a resonant frequency, connected tO the first and second parts at first and second locations to induce counterrotary movement of the first and second parts upon driving of one of the parts, the first and second locations being substantially in the second plane with both nodal axes being between the first and second locations; and means for driving one of the parts.
Claim 3
Dependent Claim
24 words
The resonator of claim 1 wherein the first and second locations are disposed on the other edges of the first and second parts respectively.
Claim 4
Dependent Claim
18 words
The resonator of claim 1 wherein the first and second parts have substantially equal mass moments of inertia.
Claim 5
Dependent Claim
17 words
The resonator of claim 1 wherein the first and second locations are equidistant from the nodal axes.
