Abstract
Abstract A connection band configuration having a minimum spring constant for a suspended body capable of rotating back and forth is disclosed. The connection band configuration comprises at least a pair of circular bands which are positioned in a horizontal plane transverse to the vertical plane which contains an axis of rotation about which the suspended body rotates. At least one pair of connection bands are employed with both bands of the pair having their centers substantially coaxial with the vertical rotational axis. One end of one band of the pair is mounted at a predetermined point on the suspended body and the other end of that band is mounted at a second point which is fixed relative to a rotational movement of the body. The other band and its mountings are a mirror image of the first band. The mountings are arranged in such a manner that when the suspended body is at its rest position, both bands of the pair are in an initial circular configuration. As the body rotates about the vertical axis, each band of the pair moves in opposition to the movement of the other band. The movement of each band takes the form of expanded and contracted circular arcs, respectively.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
A connection band assembly for a suspended body having a vertical axis about which it rotates back and forth, said assembly comprising: means suspending said body for rotational movements about said vertical axis; a pair of circular electrically conductive connection bands of an electrically conductive material lying in two parallel planes that are both traNsverse to said vertical axis, with each band comprising a circular segment with a portion of a full circle removed so as each band comprises less than a full circle and more than a semi-circle; means connecting one end of each band of said pair to said body with the circle of the pair of bands concentric with the vertical axis and the missing portions of said pair of bands defining circular arcs at opposed vertical angles drawn through said center when said body is in an initial rest position; and means connecting the other end of each band of said pair of bands to a position located other than on said body whereby the bands move in opposition to each other as the body rotates.
Claim 2
Dependent Claim
180 words
A connection band assembly for a suspended body having a vertical axis about which it rotates back and forth, said assembly comprising: means suspending said body for rotational movements about said vertical axis; a pair of circular electrically conductive connection bands of an electrically conductive material lying in two parallel planes that are both traNsverse to said vertical axis, with each band comprising a circular segment with a portion of a full circle removed so as each band comprises less than a full circle and more than a semi-circle; means connecting one end of each band of said pair to said body with the circle of the pair of bands concentric with the vertical axis and the missing portions of said pair of bands defining circular arcs at opposed vertical angles drawn through said center when said body is in an initial rest position; and means connecting the other end of each band of said pair of bands to a position located other than on said body whereby the bands move in opposition to each other as the body rotates.
Claim 3
Dependent Claim
22 words
A connection band assembly in accordance with claim 1 and further comprising for each band, circular segments, substantially between 270* to 360*.
Claim 4
Dependent Claim
45 words
A connection band assembly in accordance with claim 1 and further characterized in that as said body rotates one of said bands assumes the shape of an expanded circular arc and the other band of said pair assumes the shape of a contracted circular arc.
Claim 5
Dependent Claim
37 words
A connection band assembly in accordance with claim 4 wherein said expanded circular arc has a slightly larger diameter than said concentric circle and said contracted circular arc has a slightly smaller diameter than said concentric circle.
Claim 6
Dependent Claim
177 words
A connection band assembly for a suspended body having a vertical axis through its center of gravity about which it may rotate back and forth relative to fixed positions, said assembly comprising: means suspending said body for rotational movements about said vertical axis; at least a pair of circular connection bands (of an electrically conductive material) concentrically mounted one above the other in planes transverse to the vertical axis and having a common center point located substantially at the vertical axis of the suspended body; means for mounting one end of each band of the pair to the body and mounting the other end to a relative fixed point with the mounting positions being at spaced points on a circle in one plane and mounting one end of the other band to the body and mounting the other end of the other band to a relative fixed position, with these mountings also being at spaced points on a concentric circle in the other plane, whereby the bands move in opposition to each other as the body rotates.
Claim 7
Dependent Claim
177 words
A connection band assembly for a suspended body having a vertical axis through its center of gravity about which it may rotate back and forth relative to fixed positions, said assembly comprising: means suspending said body for rotational movements about said vertical axis; at least a pair of circular connection bands (of an electrically conductive material) concentrically mounted one above the other in planes transverse to the vertical axis and having a common center point located substantially at the vertical axis of the suspended body; means for mounting one end of each band of the pair to the body and mounting the other end to a relative fixed point with the mounting positions being at spaced points on a circle in one plane and mounting one end of the other band to the body and mounting the other end of the other band to a relative fixed position, with these mountings also being at spaced points on a concentric circle in the other plane, whereby the bands move in opposition to each other as the body rotates.
Claim 8
Dependent Claim
41 words
A connection band assembly in accordance with claim 5 and further comprising means for suspending said body including a suspension band fastened above the body at one end and fastened at its other end to the body at said center point.
Claim 9
Dependent Claim
22 words
A connection band assembly in accordance with claim 5 and further comprising circular segments for each band of substantially 270* to 360*.
Claim 10
Dependent Claim
45 words
A connection band assembly in accordance with claim 5 and further characterized in that as said body rotates one of said bands assumes the shape of an expanded circular arc and the other band of said pair assumes the shape of a contracted circular arc.
Claim 11
Dependent Claim
37 words
A connection band assembly in accordance with claim 5 wherein said expanded circular arc has a slightly larger diameter than said concentric circle and said contracted circular arc has a slightly smaller diameter than said concentric circle.
