Complete Specification Left, 6th Apr., 1900-Accepted, 12th May, 1900
PROVISIONAL SPECIFICATION.
Improvements in Means for Use in the Production of Radiation and
Light by Electricity.
We, JAMES SWINBURNE,, of 82, Victoria Street, Engineer, and CHARLES HENRY
STEARN, of 47, Victoria Street, Electrician, both in the City of Westminster,
do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus or means for obtaining radiation and
light by electricity such as the cathode ray lamps described in the Specification of
Letters Patent No. 21218 of the 24th September A.D. 1896 and in the Specifi-
cation of the application for Letters Patent No. 14059 of 25th June A.D. 1898
and especially to the means for regulating the lamps which regulation, in the
Specification of the said Letters Patent No. 21218 of 1896, is described as being
effected by a resistance in the circuit of the sparking tube, or chamber, whilst.
in the Specification of the said application for Letters Patent 14059 of 1898, it
is described as being effected by means of condensers. According to the present
invention the regulation is effected by means of a device, or devices, acting on
the principle, of counter electro-motive force, such as a choking coil, or choking
coils, interposed in the circuit of the sparking tube, or chamber, in place of
using a resistance, or condenser, or resistances, or condensers, as described in
the aforesaid specifications.
