limitations of the base claim and any intervening claims
(final rejection,
page 5). After submission of the brief, the examiner
indicated that claim 29 should have been listed with the
latter group of claims (Answer, page 2). Accordingly, claims
1 through 7, 10 through 13, 15 through 17, 19 through 25, 28
and 30 remain before us on appeal.
The disclosed invention relates to an electrodeless low-
pressure discharge lamp that uses a sintered core of
polycrystalline ferrite material so that the losses in the
core, when measured at room temperature in an alternating
magnetic field with a frequency of 3 MHZ and at a magnetic
flux density of 10mT, are at most 150 mW/cm .3
Claims 1 and 10 are illustrative of the claimed
invention, and they read as follows:
1. An illumination unit, comprising:
an electrodeless low-pressure discharge lamp; and
a supply device,
said lamp comprising a discharge vessel enclosing a
discharge space in a gastight manner, an ionizable
filling within said discharge space, and a coil for
inducing a high-frequency magnetic field which
maintains a discharge in the discharge space,
said coil including a sintered core of
