Application No. 08/251,125
output terminals; under a condition of little or no loading of
the L-C circuit, the L-C circuit having a natural resonance at
or near the fundamental frequency of the AC output voltage
and, due to resonant action, being operative to cause the
amplitude of the ballast output voltage to have a first
magnitude; under a condition of substantive loading of the L-C
circuit, the amplitude of the ballast output voltage having a
second magnitude; the second magnitude being distinctly lower
than the first magnitude;
gas discharge lamp means having a pair of lamp terminals
operable to connect with the ballast output terminals and
functional, when indeed so connected, to constitute said
substantive loading of the L-C circuit; and
auxiliary sub-assembly operable to be connected between
the L-C circuit and the inverter circuit; with the auxiliary
sub-assembly indeed so connected, and under said condition of
little or no loading of the L-C circuit, the auxiliary sub-
assembly being functional to cause the amplitude of the
ballast output voltage to be substantially lower than it would
have been in case it were not so connected.
The examiner relies on the following references:
Wallace 3,611,021 Oct. 5, 1971
Pierce 3,889,153 Jun. 10, 1975
Claims 9 and 10 stand rejected under 35 U.S.C. § 112,
first paragraph, as being based on an inadequate written
description.
Claims 1 through 8 stand rejected under 35 U.S.C. § 103
as unpatentable over Wallace in view of Pierce.
Further, the examiner objects to the specification for
failing to provide proper antecedent bases for the claimed
