1, 3, 4, and 10-13. The other claims remaining in the
application, claims 5, 7-9, and 14-27, have been indicated as
being directed to patentable subject matter.
Claim 1 reads as follows:
1. A remote ballasting apparatus for starting
and operating a gaseous discharge lamp which allows operation
of the lamp at frequencies in excess of 10 kilohertz and at a
predetermined distance from the power supply comprising a high
frequency power supply and suitable current limiting means
connected to the primary winding of an isolation transformer
comprising at least a primary winding and first and second
secondary windings arranged in a center tapped secondary
configuration and wound to minimize interwinding capacitance,
a low capacitance power transmission cable having an input end
and an output end comprising a first and second conductor with
insulation means and an outer sheathing conductor surrounding
said first and second conductor and insulated from both said
conductors connected with the input end of said first and
second conductors connected to the first and second secondary
windings respectively of said isolation transformer and the
sheathing conductor connected to the center tap of said
isolation transformer, the output end of said power
transmission cable is connected with the first conductor
connected to one end of a gaseous discharge lamp and the
second conductor connected to the other end of said gaseous
discharge lamp.
