from a combined assessment of the applied teachings, to
provide three of the two piece interfitting housings (frames)
with diametrically opposed permanent magnet structures 60, 62
disclosed by Menold (Fig. 5), clamped about and along the pipe
72. In our opinion, the suggestion for this modification
would have been derived by one having ordinary skill from the
overall teaching of Eggerichs, i.e., it would have been
appreciated by one versed in the art that the alternative
application of additional frames as taught by Eggerichs (Fig.
3) would enhance the application and effect of the magnetic
field. Our view is consistent with the teaching by Eggerichs
of the known alternatives of one (Fig. 1) or more (Fig. 3)
magnetic sources. For the above reasons, claims 4 and 6 are
determined to be unpatentable under 35 U.S.C. § 103. The
conclusion of obviousness is reached relative to the content
of claim 5 in light of the suggestion therefor derived from
the aforementioned two piece housing (frame) configuration of
Menold.
