loops;'' Lund (3,176,206) discloses having conductive loops 17, 18, 19, 20,
which have interleaved windings 67, 77, 87 (see figure 2). Moreover,
Lund discloses interleaved windings, which interact with conductive
loops 21 and 22 (see figure 2) to induce a flux, thus conductive loops 21
and 22 and interleaved windings are used for producing and conducting
flux through out the electrical device. There are also other interleaved
windings, which interact with the conductive loops to conduct and produce
flux (column 6, lines 73 - column 7, line 5., column 7, lines 36 - 41; column
8, lines 7 - 11). Also, Lund uses such interleaved windings since it is
desirable to coincide at null a signal generator to the null of a torque
generator (column 2, lines 32-34; column 7, lines 16 - 19, column [sic])
and that achieving such task by the prior art was very difficult to achieve
(column 1, lines 42 - 45).
(c) The Applicant's claim reads, "a space in between the Halbach array
and the stator; the space being radially symmetrical when the axis of
rotation is collinear with the axis of equilibrium and being asymmetrical
when the axis of rotation is displaced from the axis of equilibrium." Post
discloses that is known to have an air gap between the stator and the rotor
(column 1, lines 55, 56). Moreover, figures 1A and 1B show a gap
between the rotor and the stator. The Halbach magnets are used for
creating a strong radial stabilizing action for centering purposes of the
device (column 4, lines 57 - 59; column 5, lines 4 - 7, 52 - 67, column 6,
lines 9 - 12). Also, Post discloses inherently that the space shown in
figure 1A would be radially asymmetrical when the axis of rotation is
displaced from the axis of equilibrium since the rotor 10 and the stator
would be off centering.
(d) Claim 11 finally recites, "rotation of the Halbach array relative to the lap
windings inducing a net current in said conductive loops and in said lap
windings and generating a restorative force acting on the rotor when the
spacing is asymmetrical, tending to restore the axis of rotation to
collinearity with the axis of equilibrium.'' Post discloses that the Halbach
array of magnets induce a current with the windings to generate a
restorative force acting on the rotor when asymmetry exists (column 5,
lines 57 - 67).
